The specific embodiment
A kind of forcing press swing arm safety is fastened, and with reference to Figure of description 1 and 2, it comprises:
Support 7 as the mounting base of described rotating shaft, and is provided with the installation portion that is used for this support is installed to forcing press column one side;
Adjusting device, be arranged in the described swing arm and with described support bar axial series, have the structure of axially adjusting length at support bar.
As shown in Figure 1, in the use, described support is installed in a side of forcing press column 13, is to form a revolute pair about rotating shaft with the purpose that cooperates of support, thereby forms the swing arm of swing arm, compact conformation, and be easy to realize that known revolute pair can be applied in this programme in form, wherein be typically the axle sleeve fit form, simple in structure, low cost of manufacture; Further, can be analogous to the axle sleeve fit form that has lubricating arrangement of sliding bearing instead.Preferably, on the basis that axle sleeve cooperates pair of bearings 11 is set, corresponding rotating shaft sky is enclosed within the inner chamber of support, but cooperates with two bearings, and the rotation of realization axle can also be born the weight of whole swing arm simultaneously.More preferably, top bearing is a taper roll bearing, mainly bears the weight of swing arm and finishes certain rotation, and lower bearing is a deep groove ball bearing, mainly finishes rotating function.
Belong to process aspect about the design of the support force of rotating shaft and pendulum arm length and intensity and consider, no longer analyse in depth at this, based on this programme, these designs all are to realize very easily based on prior art.
For adjusting device, be mainly used to adjust the axial length of support bar, in conjunction with swing mechanism, the design feature of above-mentioned swing arm in other words, and forcing press disposes the space, mould district of mould correspondence, the adjustment of adjusting device is a kind of adjustment of straight length, perhaps those skilled in the art can expect adopting other adjustment mode, change straight-line guiding mechanism or device such as rotation, but the device that preferred here straight line is adjusted, the popular feature that this type of device is had is simple in structure, low cost of manufacture, and easy to adjust, as hydraulic cylinder, screw thread pair, slider-crank mechanisms etc. are the simplest with screw thread pair especially.
The introducing of adjusting device relates to a plurality of safety that are used and fastens the conforming adjustment of bearing height, and it is good to adjust convenience.
Further, fasten also and comprise in order to improve this forcing press swing arm safety of safety coefficient:
Flip flop equipment is arranged at and follows the rotating shaft rotation in the described rotating shaft; And
Thereby this programme has constituted the safety of electromechanical and has fastened structure, provides under the situation that machine security fastens again, and the locking automatically controlled to forcing press is provided, and prevents the error starting of forcing press.
Wherein, limit switch is sent a switching value or a controlled quentity controlled variable, and its driving belongs to simple triggering, thereby has determined the less demanding characteristics of flip flop equipment, has reduced the manufacturing cost of fastening based on the safety of this programme on the whole.Further, structural requirement for flip flop equipment is also just lower, just when swinging to space, mould district, swing arm provides a driving force, preferably, described flip flop equipment is a cam 9, and the push rod of limit switch has constituted the push rod of nominal cam mechanism herein, can be direct-connected to rotating shaft, because cam can be realized the motion of compound movement form, especially can the design transition district, be the preferable selection of flip flop equipment.
Described as previously mentioned, the simplest structure is a screw thread pair in the adjusting device, therefore, as a kind of preferable selection, adjusting device is the adjusting screw(rod) 1 on the support end that axially is arranged at described support bar, and screw thread pair is not only adjusted its axial length easily, and adjust the precision height, easy to adjust.
For simplified structure, be hollow-core construction with reference to Figure of description 2 described support bars, described adjusting bolt partly probes into described support bar, and is provided with adjusting nut 6 corresponding to described adjusting screw(rod) at the support end of adjusting lever.
Further, in order to improve support strength, and other annex is set easily, described support bar cooperates with described swing arm axis hole, and correspondingly, the axle during this axis hole cooperates is described support bar, and this support bar outer surface is provided with limited portion; And the hole is the corresponding hole that is arranged in the swing arm, and the upper and lower of the inherent described limited portion in this hole is provided with this limited spacing limiting section.About the selection of limited position, can be arranged on the upper end of support bar, also can be arranged on the middle part, perhaps the middle part.
As shown in Figure 2, it is a kind of form that is provided with of limited portion, just be arranged on the upper end of support bar, and preferably, for ease of processing, described limited is the axle collar, described limiting section is the interior ring to intrajugular process, distance between two limiting sections preferably, and is provided with the elastomeric element that supports described limited portion greater than the length of the described axle collar on the limiting section below the limiting section, thereby, when the slide block on the forcing press 14 met accident and falls, elastomeric element at first was compressed, and all safety that are used are fastened and all can be played a supporting role, the matching requirements that a plurality of safety are fastened have been greatly diminished, simultaneously, elastomeric element can also play good cushioning effect, prevents that support bar is subjected to bigger rigid shock.
Preferably, described elastomeric element is a spring 3, is a kind of standardized part, and design and installation is convenient.
Owing to may rotate between the hole of support bar that axis hole cooperates and correspondence, therefore,, be provided with the key 4 of restriction support bar axial rotation between support bar that described axis hole cooperates and corresponding aperture, the free degree of restriction support bar rotation for the ease of the location.
In addition, mention here that axis hole cooperates and the axle sleeve mentioned before cooperates, mechanically can think a kind ofly, the hole is not an entity, processes on entity, and cover then is a kind of entity.
Further, also comprise a pair of spring clip assembly 12, be used for the locking under swing arm user mode and the non-working condition; A connecting portion of each spring clip assembly is preset in the described swing arm, another connecting portion is arranged on the column of forcing press under installment state accordingly, with reference to Figure of description 1, spring clip can well be finished locking, prevents the swing that swing arm takes place because of external factor such as vibrations.Spring clip is a kind of preferable selection, and those skilled in the art can use the alternative that is equal to of other class, such as modes such as hook, absorption, colligations based on the consideration of the swing under non-artificial will that prevents swing arm.
