Description

The drawing that the present invention relates to sheet material can be used as the structural material in the building or the web-shaped product of ornament materials or other purposes with production.

Many relevant schemes that draw the production technology of Web materials had been proposed so far.Existing this class scheme is normally made the sheet material of flat earlier, sheet material is cut into certain style, so that next step becomes desirable shape of a mesh with its lateral pulling again.Cutting and/or the employed operation of lateral pulling can cause forming significant stress in the scope of material plate, and various technological parameters also play restrictive effect to existing product at shape, size, style and other aspect of performance, thereby have limited the application facet that may accomplish by this series products.Have any problem in the relevant production of many existing schemes owing to final products or defective fails to reach the realization commercialization.

In the existing scheme, there are some to draw, to make web-shaped product to each parts of material plate.What other existing scheme had need carry out bending or twist and warping to the material plate each several part.Also have some existing schemes to carry out some multi-form comprehensive deformation processing to material plate.Those schemes that need carry out bending or twist and warping are usually than those scheme less energy consumptions that need draw material plate, thereby in the commercial attraction that has more.

US Patent specification 895,923 has been introduced a kind of equipment that draws the slotted eye metallic plate, during drawing a seam orifice plate material is sent in the pair of interacting stationary mold.The shape of mould should be made and make it be enough to produce desired drawing effect, and should work good with the seam hole that forms on the sheet material.Pulling process promptly is pressed in the mold process at sheet material and carries out continuously.

A kind of like this technology of narration in US Patent specification 890,126, each joint between in a row respectively hold in the seam hole on the metallic plate is twisted and warped, and it is not on the same plane with plate plane, draws sheet material then, makes the formed expansion of pores of twist and warping.

US Patent specification 1,321,089 discloses a kind of equipment slotted eye sheet material in this equipment is drawn through opposed drawing dish.As the sheet material that institute's continuous drawing forms, its adjacent mesh is reverse each other, and the lath that does not draw the part longitudinal extension by sheet material between each mesh is separated, thereby has improved the intensity of watt ridge type final products.

US Patent specification 843,728 discloses a kind of equipment of continuous drawing slotted eye sheet material, and in this equipment, sheet material is drawn on the processing edge face of band tooth or watt ridge shape by the rotary drum that tooth is arranged.There is not to illustrate the frictional force of how controlling between sheet material and the processing edge face to make the method for even matter product.

US Patent specification 780,173 discloses a kind of equipment, and the pivotally supported crooked hook of this equipment utilization draws slotted eye sheet material.When this sheet material is that this bending hook acts on the core of the slice between the end that extends in seam hole vertically arranged in a straight line when being supported on each end in these seam holes.

An object of the present invention is to provide the technology that a kind of improved manufacturing draws Web materials, go out product miscellaneous, and in manufacture course of products, can not resemble and in material, produce stress many prior aries with this explained hereafter.Some other purpose of the present invention also has: product with the performance that product had of coming out with this improved explained hereafter and a kind of equipment that can be used for producing this product are provided.

Material plate shape flat used in the present invention, and available such as rolling or extrusion process manufacturing.Though preferably adopt the simple original plate of rectangular cross section, the present invention also is applicable to the sheet material of different shape cross section, comprise the sheet material that outstanding fin is arranged from the total plate face of sheet material substantially.The present invention also is applicable to the sheet material made from such method: with the vertical or horizontal bending of sheet material, make initial feed, though make it keep smooth shape basically, but have a series of folding or watt ridge shape parts, and the degree of depth of material plate is greater than the degree of depth of the plate of being made by material plate.

The present invention is applicable to the sheet material of various different lengths, width and thickness, but be specially adapted to draw the production technology of product, and can adapt to the continuous production processes that draws Web materials from continuous coiled strip sheet material manufacturing from the length sheet material manufacturing more much bigger than width.

The present invention preferably is applied to sheet metal, but any other substantially rigidity but material such as thermoplastic with ductility, also available method of the present invention is made the drawing Web materials.

During Web materials constructed in accordance, on material plate, remove or cutting out section sheet material earlier, form the slotted eye or the seam hole of predetermined pattern at plate surface.On raw material, form the method in slotted eye or seam hole, not key issue for purposes of the invention, and " slotted eye " speech typically refers to by formed aperture of cut-out material plate or weak part on material plate, and " seam hole " speech refers to that then those do not have the real position that removes any material from relevant position on the material plate through cutting off or attenuating.At the remainder of this specification, " slotted eye " speech is in order to represent the position of any formation like this.Some schemes that draw Web materials with aforementioned manufacturing are different, and technology of the present invention does not cause the sheet material near each slotted eye end to bear any sizable stress, thereby need not careful especially the processing in the formation or the shape of each slotted eye.

The slotted eye style that forms according to the present invention should be got the parallel ranks that comprise a plurality of slotted eyes, and these ranks preferably extend on the direction parallel with each edge of sheet material.The alignment direction of the ranks of slotted eye is preferably with respect to sheet material axis longitudinal extension, but also can horizontal expansion.Below for ease of saying something, be parallel to sheet edge with the ranks of slotted eye by longitudinal extension and narrate.

In the style of slotted eye formed according to the present invention, each slotted eye of arbitrary ranks is overlapping with the different slots bore portion of the ranks that laterally adjoin in its each end.This slotted eye promptly repeats to form on whole sheet material with this style regularly.

The regular style that is repeating like this forms a configuration, has an overlapping region between the opposed end of second slotted eye in the end of first slotted eye and the next row that adjoins in this configuration in delegation; Equally, the other end of second slotted eye is overlapping with the opposed end that the next one adjoins the 3rd capable slotted eye, and so the vertical direction of this slotted eye of crosscut is extended in a plurality of overlapping regions that form on diagonal.For the purpose of explanation, these overlapping regions are referred to as " slice " here, therefore can be considered as the ranks that almost parallel extends across slotted eye to a series of slice diagonal.

Technology of the present invention comprises the slice diagonal of each arranged spaced crooked and draw sheet material.For example, in a form of the present invention, the flexible one-tenth of each slice diagonal makes itself and sheet material not on same plane, for example makes it be higher or lower than the sheet bending horizontal plane at place before.As another kind of selection scheme, can this slice diagonal is crooked in plate plane in another form of the present invention; At this moment this slice preferably winds the axis bending perpendicular to plate plane.

The preferably bending in turn of the slice diagonal of each arranged spaced, the whole slices on any diagonal are crooked simultaneously.Each second slice diagonal can divide two or more sets to carry out bending, will be very complicated by the plant equipment of organizing the required usefulness of crooked slice diagonal.

Each independent slice in treating crooked slice diagonal is to define at least two enterprising line bend in position between the slotted eye on limit of slice.Slice in crooked each slice diagonal of crossing carries out bending by same mode, and bends to same degree, makes slice diagonal in the bending, its each slice still be in substantially parallel plane in BENDING PROCESS and after crooked.In case of necessity, the degree of crook between each diagonal can be different.

The bending of the in check and meticulous qualification of each slice is a main feature of the present invention, and it can put into practice in any suitable manner.We preferably clamp two opposed faces of sheet material, and the both ends for the treatment of each crooked slice are clamped between the machined surface of opposed flector in the place of adjoining the crooked line of about needs.

In order to realize bending each slice in each diagonal required the time, flector preferably is contained on the carrier bar, and every carrier bar carrying flector acts on the similar position of corresponding slice.The a pair of carrier bar that is preferably carrying opposed flector maintains static in bending operation, and another then moves through on the pairing circular arc of angle of bend of the end for the treatment of crooked slice carrier bar simultaneously.In addition, by making one of corresponding carrier bar centering on this plane and another motion on perpendicular to this plane obtains a relative circular arc bending motion.

Each slice preferably bend to sheet material not in one plane, and perpendicular to crooked on the direction longitudinally of plate plane.Like this, sheet material just can continue the extension of moving towards towards same longitudinal extension with crooked preceding the same after bending.But it is not requisite carrying out bending in vertical direction, and if with slice when carrying out bending with its a certain angle that vertically forms, the sheet material after the bending then, its trend can depart from introduce sheet material vertically.Under a kind of form in back, material plate reaches in its plane and draws on the vertical direction on its plane, and effect is fine.

In an embodiment of the present invention, slice be bent to sheet material not on same plane, the slice diagonal that has been bent is that the crooked group bar diagonal that the not sweep of diagonal extension adjoins with it separates, and the plane of this unbent part then still is parallel to the plane of material plate.The not sweep that the slice diagonal that will adjoin in the diagonal extension separates also is a slice diagonal of former sheet material, but the slice that is begun by slotted eye opposed end in the ranks that adjoin is formed.When the plane of material plate was horizontal, so the drawing sheet material that forms extended in above or below the material plate plane.

Each slice diagonal is bent in plate plane in an embodiment of the present invention, each diagonal of crooked back for the not bend branch that on diagonal, extends separately, this not sweep between slotted eye that vertically adjoin, parallel to each other, comprise unbent slice and substrate.Self-evident, this structure and slice diagonal are bent to sheet material not similar at conplane embodiment.Substrate and not crooked slice also are parallel to slice in the sheet material that does not draw.

The shape of the mesh that forms except that be subjected to plate plane curve inwardly or bandy the influence, also the angle of passing through with the bending of the repeat pattern of the horizontal spacing of the relative length of slotted eye, each slotted eye, slotted eye and slice is relevant.Mesh after the drawing is the quadrangle aperture usually, and tetragonal opposed edge is to parallel to each other separately.

Above-mentioned bending process can be finished with any suitable machinery.Carrying out the crooked comparatively ideal practice at present is that each slice was bent required radian, so that produce required angle in formed mesh.The resilience of material can make the angle in the finished product reduce to some extent than the radian of the curved mistake of slice usually.If slice was not bent a radian, then can carry out punching press so that required flexibility to be provided at the slice diagonal.No matter adopt any method to carry out bending, the stress that material plate is subjected to is quite little, therefore can before bending the slotted eye material plate be carried out finishing.This performance has an important benefit in practicality, promptly can under the more smooth situation of the slotted eye shape of sheet material, apply or finishing, this more apply under the complicated situation than mesh shape after drawing certainly or finishing much easier.

Can expect to get from the style of slotted eye the trend on the limit that is parallel to material plate with the above, and when the line of the end of slotted eye is got material plate perpendicular to the limit of material plate in ranks at interval, the drawing sheet material of making, it respectively draws each limit of slotted eye and still is parallel to each limit of drawing sheet material.But find that always in this drawing sheet material, the form of mesh is crooked with respect to each limit of sheet material.Therefore if Web materials will be installed on the corner, one or more right angle the time, each limit should be repaired.

The present patent application people finds, in order to need not to repair each limit of this netted sheet material, can make the limit that is parallel to material plate by the style that makes slotted eye but be not orthogonal to slotted eye and the slotted eye style on the material plate is inclined to a certain degree is configured to offset the mesh style with respect to the inclination that draws each limit of sheet material to be connected at interval the end of the slotted eye of ranks.The slotted eye style is directly proportional with the cornerwise angle of bend of this slice for avoiding the mesh style needed inclination angle that tilts.

Can also optionally further process according to a further aspect in the invention with the product that said method is made.Through the product after further processing, its shape was relevant with original product processed, but difference is arranged.For simplicity, rework process is called " phase I " and second stage here " manufacturing procedure.

The second stage operation series of parallel slice diagonal that intersects with the crooked slice diagonal of crossing of phase I that comprises crooked original unwarped optionally.The bending direction of second stage bending operation is opposite with the phase I preferably.The bending of second stage can be undertaken by similar mode of phase I, but flexibility can be different.In case of necessity, the bending of phase I can be carried out in the material plate plane, and the bending of second stage can be carried out outside the material plate plane, or adopts opposite mode.For ease of producing, each crooked best both of stage carries out in the material plate plane, or the both carries out outside the material plate plane.

After the bending of first and second stages outside plate plane, the nonoverlapping substrate portion in end of adjoining slotted eye still is on each plane that is parallel to the material plate plane.After the bending of first and second stages in plate plane, substrate portion still with unbent sheet material in line.As long as the bending in first and second stages of each slice is not to carry out on perpendicular to the direction on original plate plane, the shape of each mesh after the second stage bending is the hexagon aperture usually.

What speak of above is the forming process of the Web materials medium dip style made the phase I.But this phenomenon is can be not problematic, as long as the phase I product is through the second stage operation, and the used angle of bend of back one operation and phase I is identical.The acting in opposition effect of second stage has been offset the effect that is formed slopely of phase I.Self-evident, can utilize this effect further to change the scope that adopts the obtainable product material of the present invention in case of necessity.

Best form of the product that the first and second stage bending operations are made is to draw web-shaped product, this drawing web-shaped product is to be made by flat sheets, this flat board cuts into predetermined well-regulated repeat pattern in advance, this style comprises the parallel ranks that comprise a plurality of slotted eyes, the slotted eye of any delegation, overlapping in its end with the different slotted eyes of its one or more ranks that laterally adjoin, thereby form a plurality of slices, constitute the overlay region between the ranks of the slotted eye that these slices adjoin in each end of corresponding each slotted eye, it is characterized in that, between the opposite end of the slotted eye that in the given side of a slotted eye of first row and second row that adjoins, adjoins, between slotted eye that the other end of the described slotted eye that adjoins and the third line of adjoining adjoin opposed, and each interval slice diagonal that the slice in turn between the slotted eye opposite end of adjoining like the same item of extending on the leap sheet material diagonal is formed is to be bent processing in turn, when crooked, be to carry out on two positions between each slotted eye on limit of each slice that all slices defined on the diagonal in office, each slice on each slice diagonal carries out bending by same mode and same amount of bow, and the cornerwise slice of slice after feasible being bent is still in substantially parallel plane.The product that is formed by the phase I can make it to stand the bending of second stage, thereby forms second kind of preferential recommendation form of product, wherein with the crossing slice diagonal bending in a similar manner of described interval slice diagonal, to form the another kind of web-shaped product that draws; Wherein, between the slotted eye that adjoins on the sheet material nonoverlapping zone before the bending still in the plane at described sheet material or be parallel to this plane.

The present invention also provides a kind of equipment that can bend slotted eye sheet material by the preferential recommendation form of method of the present invention.Particularly, this equipment can outwards bending original plate on its plane in second stage in phase I and selection.

Therefore, equipment of the present invention comprises a conveyer, bends platform in order to raw material tank orifice plate material is guided and sends into the phase I.Phase I bends platform two groups of opposed carrier bars, and sheet material can be sent into respectively by conveyer and organize between the carrier bar.Each carrier bar carrying is the flector of configuration at a certain distance, and is configured in along diagonal on the path of the sheet material that collapsed, and aims at the slice diagonal that extends along first direction on the sheet material that collapsed.Each flector is configured on each carrier bar, treats crooked slice in line with corresponding.

Each is organized carrier bar when work and one and sends to backing mechanism and interrelate, thus make respectively organize carrier bar at least one carrier bar can towards or the sheet material of its opposed carrier bar and intervention dorsad and moving, thereby sheet material can be clipped between the carrier bar in case of necessity.Also interrelate during at least one group of carrier bar work, can make sheet material make limited bending motion, thereby make the selectivity of sheet material be bent to the phase I product that may and form a drawing by flector with a mechanism.Best one group of carrier bar is motionless in bending step, and other group of carrier bar and a rotating mechanism interrelate, make the common crosscut plate plane of the limited motion of passing through circular arc that two carrier bars are done in this carrier bar group, and that other group of carrier bar is maintained fixed is motionless, thereby makes sheet material pass through the selectively crooked drawing product that forms the phase I.

Equipment of the present invention can also comprise that second stage bends platform, and second stage bends platform after the phase I bends platform, bends platform with the phase I and separates.Second stage bends platform to be had with the phase I and bends the corresponding some critical pieces of platform, is configured in the phase I and bends on the opposite diagonal of each carrier bar of platform but second stage bends each carrier bar (with the conveyer of preferential recommendation) of two groups of opposed carrier bars of platform.So second stage carrier bar and the opposite slice diagonal of the suitable crooked original unbent direction of relevant flector thereof.

Accompanying drawing is the concrete form of the product can be successively made according to first and second stage procedures of the present invention.One of them accompanying drawing is to draw for the working condition of assisting to understand the preferential equipment of recommending of the present invention.Self-evident, these accompanying drawings only are for example, are intended to assist to understand content of the present invention.In the accompanying drawing:

Fig. 1 to Fig. 4 is the schematic diagram that sheet material bends outside its plane;

Fig. 1 is that part adds operation plate plane figure afterwards through the phase I;

Fig. 2 is the side view of Fig. 1 sheet material;

Fig. 3 is that the sheet material of Fig. 1 partly passes through second stage manufacturing procedure plane afterwards;

Fig. 4 is the side view of Fig. 3 sheet material;

Fig. 5 to Fig. 8 is the situation that sheet material bends in its plane, and the situation with Fig. 1 to Fig. 4 is similar respectively.

Fig. 9 is to the schematic diagram that is the present invention's operation sequence scheme of each part of equipment of preferably recommending.

From Fig. 1 left side can know see sheet material do not bend before the style of each slotted eye 10 be to line up parallel ranks along sheet material.Among Fig. 1, each dash area is represented slice 20, and they extend in and stride across on all parallel diagonal shown in the broken broken line on the sheet material.Slice diagonal (not with dash area) was opened the diagonal of slice in 1 to 5 minute at interval, and was parallel to them.

Each slice 20 on the diagonal 1 to 5 x along the line in turn and y make sheet material along the expansion of below, material plate plane, as shown in Figure 2 around radian 30 bendings.As we can see from the figure, spread angle alpha is about 45 degree, but also can get 0 degree to the number of degrees near 180 degree angles.

Should be noted that slice 20 BENDING PROCESS and crooked after keeping parallelism each other.As can be seen from Figure 2, the interval slice diagonal between the diagonal 1,2,3,4 and 5 after the bending is because their plane is parallel to the material plate plane after bending, so look like some straight lines.It can also be seen that the situation of change that output presents that has a down dip from the court that the input of the level of arrow A is fed to arrow B from Fig. 2, it is relevant that the inclined degree that output is presented and spread angle alpha and slotted eye dispose style.

As shown in Figure 3 and Figure 4, crosscut contains slice diagonal A, B, C and D bar p along the line in turn that the slice diagonal of slice 20 extends and q around radian 40 bendings in second stage.The angle beta of second stage manufacturing procedure is identical with angle [alpha], forms a symmetrical mesh, as shown in Figure 4.

Substrate regions 50 between each end of each slice that bends in first and second manufacturing procedures still is in the plane that is parallel to the material plate plane after the first and second stage process operations.The angle of bend that each embodiment adopted makes the input of second stage present angle (arrow C) and presents the angle corresponding to the output of phase I, but the output to second stage when the β angle equals the α angle is presented (arrow B) and is played corrective action, makes output present the input that is parallel to the phase I.

Can see that from Fig. 1 to Fig. 4 slice becomes 90 degree around the bending of x, y line and p, q line to slotted eye.This angle of bend is not main, but adopts this angle of bend just can make the trend of sheet material in parallel lines.The width of sheet material on plane that phase I or second stage manufacturing procedure and unlikely change are introduced, this is because whole pulling process of sheet material are to carry out in perpendicular to the plane on material plate plane.

Can see BENDING PROCESS in the material plate plane from Fig. 5 to embodiment shown in Figure 8.From Fig. 5 and 6, and can be clear that respectively the bending of slice is all carried out among Fig. 7 and 8 in plate plane.Corresponding with Fig. 1 to Fig. 4 of the numbering of Fig. 5 to Fig. 8 and letter, the similar operations of being narrated with Fig. 1 to Fig. 4 is applicable to Fig. 5 to Fig. 8.

In the embodiment of Fig. 5 to Fig. 8, pulling process carries out in the material plate plane, and substrate 50 and slice 20 still are in the plate plane in whole two phase process.In this embodiment, bend angles alpha is about 30 degree.

In Fig. 1 to Fig. 4 and Fig. 5 to Fig. 8 embodiment shown in respectively,, all be equal length and be that longitudinal pitch or horizontal spacing all are equally spaced at each slotted eye that material plate forms.In above-mentioned limit range, can carry out a series of changes to the slotted eye style and the model type of formation like this.For example, not only can change the relative length and the spacing of Fig. 1 each slotted eye to the material plate shown in Figure 5, and the slotted eye length on each spaced rows can be different, the longitudinal pitch of each slotted eye can be different on spaced rows, the horizontal spacing of each slotted eye can be different on spaced rows, the width of slotted eye can be different on spaced rows, and substrate regions can also depart from the center of the slotted eye that defines them.The multiple combination of above-mentioned change also is feasible.

Therefore technology versatility provided by the invention is extremely strong, can be in order to make various forms of products.The stress that produces in the final products is less, thereby the stamping press of the required usefulness of production and power consumption are all little than existing many known technologies.In key diagram 9 before the illustrated operation sequence, further specify characteristics earlier as the made equipment that comes out of a part of the present invention.In the apparatus-form that above-mentioned simple the present invention who introduced preferably recommends, be provided with two and bend platform.Though following explanation continues to speak of two individual equipments that bend platform, and is self-evident, this bends the station is to operate respectively, and in fact can separately be arranged on different positions.

Respectively bend platform and comprise two groups of opposed flector carrier bars, at least one bends platform and is provided with conveyer.This conveyer or each conveyer have a driven rod with relevant transmission hook.

Respectively bending platform has one group of carrier bar (hereinafter referred to as movable carrier bar) can put in order group to move in limited radian, usually the plate plane that forms on equipment of crosscut.As mentioned above, each carrier bar in respectively bending two groups of carrier bars of platform all is loaded with the flector of spacing configuration, and each flector is placed on each carrier bar, with the slice for the treatment of crooked sheet material in line.Flector on the position of each carrier bar and/or each carrier bar is preferably adjustable or be easy to change, and equipment can be adapted to treat the different slots cellular type sample that forms on sheet material.

Send to backing mechanism and interrelate at least one carrier bar and in the carrier bar respectively organized that respectively bends platform, this send to backing mechanism in the sheet material forming process, relevant carrier bar can be driven to expel its opposed carrier bar and intervenient sheet material.Each carrier bar group preferably has only a carrier bar (to call clamping beam in the following text) to move like this.Self-evident, in bending the operation process, can not make the carrier bar group (to call fixedly carrier bar in the following text) of arcuate movement, in any case a movable carrier bar at least also should be arranged, in order to clamping on demand or release sheet material.

Operation sequence shown in Figure 9 is meant the forming process of having opened the initial flat panel material of slotted eye in advance, during shaping, as stated above in more detail referring to figs. 1 through Fig. 4, sheet material is bent on the plane different with sheet material.Equipment has adopted that of above-mentioned introduction a kind of, bends in its first and second stage conveyer all is housed on the platform.

Among Fig. 9, the action of each assembly shown in the left hurdle is that sequenced step procedure is carried out, shown in the remainder among the figure.When certain specific components is not moved, represent that the thick line of this assembly actuating wire just keeps horizontal level in certain particular step.The lifting of thick line represents that action changes another state over to from a state.The fine rule of band arrow is represented the next procedure that each step at the end should change over to.Like this, as we can see from the figure, after step 11 finishes, repeating step 1, new circulation begins again.By tape character " with " fine rule of interface point represents to comprise release mechanism is installed, this release mechanism guarantees to have only after all previous and associated actions of this interface point finish, next step action could begin.

In step 1, two driven rods that bend platform engage with sheet material, and sheet material is measured reach in accordance with regulations, make each end and the flector lateral alignment of selected slice.Each transmits hook is for the sheet material of engaged at end forward at relevant slotted eye designs, but part draws because each slotted eye bends on the sheet material at station in trend second, therefore respectively bends the desirable different shape of transmission hook of platform.Transmit hook and can load onto spring,, or utilize the elasticity that sheet material had in the forming process to enter in the slotted eye so that can drive in the slotted eye.

In step 2, the movable carrier bar group that second stage bends platform moves on to one, and " the " center " position, in this position, each flector on carrier bar sheet material carrying out next step position upper support that bends.

In step 3, two bend the movable of platform and fixedly the clamping beam of carrier bar group all shift to their opposed clamping beams separately, and sheet material is clipped between the opposed flector of each bending position.Four holding actions just carry out steps 4 after finishing.

In illustrated program, step 4 comprises two actions.In these actions, the flexure operation that bends platform with second stage is even more important.In this course of action, movable carrier bar is made arcuate movement with respect to fixing carrier bar, and this radian promptly forms desirable angle of bend in original end of the slice of crooked mistake.

Another action of step 4 is not too important, because it need not to carry out in this step in program.This action that makes conveyer move on to home position can step 2 to any one step of 5 be carried out in diagram.

After step 4 action was finished, step 5 just discharged clamping beam 3, and clamping beam 3 is to form the fixedly part of carrier bar group of second stage.Step 6 with second stage become the system platform still the movable carrier bar of clamping sheet material turn back on this transmission hook that bends platform and the position that sheet material engages.

Step 7 is to unclamp the clamping beam 4 that forms the movable carrier bar group part of second stage.Step 8 has two actions, and these two actions can be independently.An action of step 8 shown in the figure is movable carrier bar bends sheet material on crooked this platform of platform in the phase I actions.Another action of illustrated steps 8 is the delivering position that the movable carrier bar of second stage is turned back to they.This action can be in diagram program after the step 7 and any time before the repeating step 1 carry out.

Step 9 is to unclasp the clamping beam 2 that the phase I bends the movable carrier bar group part in station.Be step 10 after this action, step 10 will bend each movable carrier bar of station the phase I and turn back to their delivering position.At last, in step 11, will bend the phase I platform fixedly the clamping beam of carrier bar unclamp, at this moment can begin each operation program again.

The details that is noted that the said equipment and this equipment operation program only is for example, should not be considered as limitation of the present invention.Particularly, can also design other energy and the above-mentioned mechanism that on each position of slotted eye flat board, produces flexure operation like that.

At last, self-evident, on the basis that does not break away from the scope of the invention, can carry out other various modifications and/or change to the present invention.
