Description

A kind of pneumatic diel switching device shifter

Technical field

The utility model relates to the diel field, relates to a kind of pneumatic diel switching device shifter that uses in the diel specifically.

Background technology

Along with the personalized development of automobile, identical automobile has different configurations, will produce a lot of different versions on the corresponding Auto-body Panel, as the few hole of porous, fenestrate windowless, special little moulding is arranged or does not have or the like situation.If increase mould in addition for the product of these different editions; Not only improved the development cost of car load; And can't on production line, switch fast; In order to save development cost and switching time, will try every possible means on same group of mould, to stamp out the product of different editions, this is a problem of mould development personnel research always.Design the earliest is to assign to satisfy the demands through the operate portions of using different length, but because can't mistake proofing on the mould, working position wearing and tearing especially severe, and can't automatically switch on line, no longer be used gradually.In recent years mould manufacturing company begins to design various pneumatic switching device shifter and is installed on the mould in order to satisfy this respect requirement of client, makes mould can realize the switching of online different editions stamping parts.But these devices have a lot of different defects, such as for heavy switching mechanism is switched, have used the cylinder of high thrust; For cylinder and switching device shifter are installed; The strength structure of mould is destroyed or is strengthened, and causes the mould development cost high, reliability, maintainable poor; The switching device shifter guide effect is poor, the security set imperfection.

Summary of the invention

In order to overcome the problem that above-mentioned technology exists, the technical problem that the utility model will solve provides a kind of pneumatic diel switching device shifter.This switching device shifter can on-line automaticly switch, and switches between body and the last mould body accurately to lead, and safe error prevention device is arranged.

The utility model is achieved through adopting following technical scheme:

A kind of pneumatic diel switching device shifter comprises horizontally disposed pull bar, and an end of said pull bar is driven by external force; The other end and the static connection of push-and-pull piece, said push-and-pull piece are positioned at the lower surface of clamping cap and are fastenedly connected with it, and the lower surface of said pressing plate also is provided with two groups of wedges; The cross section of said every group of wedge is two unfilled corner rectangles that are oppositely arranged, and the hypotenuse of said two unfilled corner rectangles is complementary, and one group of said wedge is installed on the switching body; Another group is installed in the push pedal, also comprises the guiding mechanism that at least two groups are made up of the guide pillars and bushes that matches each other, and guide pillar cooperates with the guide pin bushing glade plane space; Said guide pillar is installed on the mould body; Said guide pin bushing is installed on the said switching body, and the compression spring is installed on the binder core, and pressing plate and last mould body are fastenedly connected.

One end of said pull bar passes through air cylinder driven.

Said pressing plate is pressed on said going up on the mould body with said push pedal.

Said switching body hangs over said going up on the mould body.

The beneficial effect of the utility model is:

The pneumatic diel switching device shifter of the utility model can not increase die size, does not destroy under the situation of mould strength, and on-line automatic switching is switched between body and the last mould body and can accurately be led, and safe error prevention device is arranged.

Description of drawings

But Fig. 1 is the structural representation side view of the utility model under the punching press state.

The structural representation side view that Fig. 2 is the utility model under can not the punching press state.

Fig. 3 is the structural representation side view of the utility model under changeable state.

Fig. 4 is the structural upright sketch map of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.

A kind of pneumatic diel switching device shifter comprises horizontally disposed pull bar 2, and an end of said pull bar 2 is driven by external force; The other end and 3 static connections of push-and-pull piece, said push-and-pull piece 3 are positioned at the lower surface of clamping cap 7 and are fastenedly connected with it, and the lower surface of said pressing plate 7 also is provided with two groups of wedges 4; The cross section of said every group of wedge 4 is two unfilled corner rectangles that are oppositely arranged, and the hypotenuse of said two unfilled corner rectangles is complementary, and one group of said wedge 4 is installed on the switching body; Another group is installed in the push pedal, also comprises the guiding mechanism that at least two groups are made up of guide pillar that matches each other 10 and guide pin bushing 9, and guide pillar 10 cooperates with guide pin bushing 9 glade plane spaces; Said guide pillar 10 is installed on the mould body; Said guide pin bushing 9 is installed on the said switching body 5, and compression spring 6 is installed on the binder core, and pressing plate 7 is fastenedly connected with last mould body.

One end of said pull bar passes through air cylinder driven.

Said pressing plate is pressed on said going up on the mould body with said push pedal.

Said switching body hangs over said going up on the mould body through safety screw 11.

The operation principle of the utility model is following:

According to the situation of three state shown in the accompanying drawing be: but the side view punching press state in Fig. 1, and cylinder 1 and pull bar 2 are after push-and-pull piece 3 is connected; Promote push pedal 8 motions, make wedge overlapping about in the of 4, at this moment can carry out press work; Last mould body moves down, and after the binder core puts in place, switches body 5 and moves down; Compressed nitrogen spring 6, press work is accomplished in final workpiece 12 work; Side view in Fig. 2 can not the punching press state: wedge 4 is staggered up and down; Last mould body moves down, and after the binder core puts in place, switches body 5 and moves down; Compressed nitrogen spring 6; Because wedge 4 staggers, final workpiece 12 can not reach the operating position, and diel this moment is in non-punching press state.Side view switching state in Fig. 3: during switching device shifter, need be at the moulds open state, at this moment through manual intake valve; Air inlet drives cylinder and pushes away or spur push pedal 8, reaches the position that wedge 4 overlaps or staggers; At this moment 8 of push pedals receive cylinder force, in the slide guide motion of pressing plate 7.Switch body 5 when up and down, used 4 groups of guide pillars 9 and guide pin bushing 10, can be up and down flexibly when having guaranteed 5 punching presses of switching body.4 groups of safety screws 11 are installed to be avoided when nitrogen spring 6 inefficacies or the disengaging of binder core, switching body 5 and deviating to go up the production risk that mould body causes.
