Description
Technical field
The present invention relates to the diel field, the punching parts that switches to two states in the especially same secondary mould fast provides a kind of stamping die to use switching mechanism.
Background technology
In recent years, along with the automobile industry develop rapidly, increasing car manufactures is in order to satisfy the different levels consumer demand; Usually adopt the part of certain vehicle is adjusted; Produce the vehicle of different styles with this; Like the top cover in the automobile is exactly very typical part; There is the top cover in band skylight also to have and is not with the skylight; On the other hand in order to practice thrift cost; The mould that producer all requires mould supplier to provide can satisfy simultaneously two states part production and do not increase die sinking cost and other any expense; Die industry is competed also more and more fierce simultaneously, and is increasing shorter and shorter with the friendship mould cycle in view of cost pressure, changes traditional Sheet Metal Forming Technology, simplifies and the innovation mould structure; Shorten and hand over the mould cycle; Become the necessary Consideration of mould design; Also become the effective way that improves enterprise's Tool and Die Technology level and competitiveness.
Summary of the invention
The object of the present invention is to provide a kind of stamping die to use switching mechanism, this mould structure can address the above problem not increasing the mould operation, not increasing under the situation of jig frequency.
A kind of stamping die is used switching mechanism, comprising: movable punch; Drive guide plate, the inclined-plane is arranged on this guide plate, and it can make horizontal applied force be converted into vertical under the effect of power; Planker; Planker drives; Guide plate; The pressure source of holding pad; The spring that can raise planker and movable punch; Upper bolster is provided with guide pillar, and movable punch is provided with guide pin bushing to guarantee the operating accuracy of movable punch; Upper bolster and movable punch are provided with guide plate respectively, and make spigot surface near the movable punch working face; Lead with guide plate between planker and the upper bolster; The stroke limit of movable punch is by gripper shoe and the acting in conjunction of stop screw assembly; The descending stroke of stop screw control movable punch also plays the effect of fixing spring; The clamp of guide pillar front end is the safe limiting plate that prevents that movable punch from coming off; Be provided with between planker and the movable punch and force to retract piece; It is when spring failure, can mandatoryly up to promote movable punch that pressure retracts its effect of piece.
Further, but to drive be the double-acting cylinder of back and forth movement to employed planker.
Further, employed holding pad pressure source is a nitrogen spring.
Further, the restoring force of movable punch is provided by spring; The power of spring or nitrogen spring is enough lifted movable punch and planker simultaneously; Movable punch and planker bottom surface in working order the time is bumped extremely.
Further, movable punch holding pad before work provides enough pressure to compress tablet.
The invention has the beneficial effects as follows: utilize above-mentioned frame mode, can accomplish the switching of two states, when punching press, do not need form removal directly just can switch through the driving force that cylinder provides at same preface mould; The few assembling of the number of parts of this mechanism is simple in addition.

The specific embodiment
Specify principle of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the movable punch in this mechanism carries out punching press to part a working state figure: its duty is to be changed by duty shown in Figure 2; Through cylinder 11 afterbodys are inflated; The thrust promotion planker 5 that lets cylinder produce left slides left; When the driving guide plate A contact on being installed in planker is installed in the driving guide plate B on the movable punch; Because two contact-making surfaces are inclined-planes, under the effect of thrust left, movable punch can progressively move downward; Inclined-plane stroke until two driving guide plates finishes; At this moment movable punch just moves to bottom dead centre, and gripper shoe 16 and stop screw 17 tighten together by screw; Lower dead point position to movable punch plays restriction jointly; The spring that be contained in the movable punch this moment is in pressured state; Planker continues under cylinder thrust to left movement; The wedging amount of the horizontal slide guide face of driving guide plate A and B is increasing; Cover stroke up to cylinder; Planker stops to slide; Pressure retracts piece and at this moment is in the leftmost side; Keep this state just can production A condition part 13, part 13 comprises following characteristic: the punching deburring of switching mechanism region, hole flanging, shaping, otch, flange etc.; Movable punch 8 holding pad 1 before work has made punching parts A be in impaction state, and pressure-plate-force is enough.
Fig. 2 is the movable punch in this mechanism does not carry out punching press to part a working state figure: its duty is to be changed by duty shown in Figure 1; Through double-acting cylinder 11 tops are inflated; The pulling force pulling planker 5 that lets cylinder produce to the right slides to the right; When the inclined-plane contact that drives guide plate A drives the inclined-plane of guide plate B; Because two contact-making surfaces are inclined-planes, make progress under the effect of pulling force to the right of restoring force and cylinder receiving spring, movable punch can progressively move upward; Restoring force until spring is zero; At this moment movable punch just contacts with the bottom surface of planker; Planker finishes the back stop motion in the cylinder backhaul; Pressure retracts piece and tangles movable punch at this moment.Keep this state just can produce B state part 14; 14 do not have any operation content in the switching mechanism region, and part can not be pressed onto by movable punch.
