Description
Technical field
The present invention relates to the drawing die in technology of die manufacturing field, specifically one utilizes the time relay to make drawing die realize double blank, and can solve a kind of mould structure of de-material distortion.
Background technology
General double blank drawing mold structure is all adopt blank holder and the first binder of molding concave die, and when continuing to move downward, punch contacts with plate, drives plate to flow into concave die cavity.Arrive after bottom dead center press ram up, counterdie air cushion pressure is by de-for blank holder jack-up material simultaneously.But this structure is for some small-sized non-enclosed binders and profile irregular stamping parts molding effect is bad, easily occur that forming surface central plane degree is bad, and the situation that there will be drawing and moulding profile instability because air cushion pressure size is unstable.In order to reach the requirement of part flatness, material pressing device must be increased in Central of the parts plane, just there is upper and lower double blank in such mould, when die sinking, blank holder upwards jack-up puts on the de-material power of forming part one, in patrix, de-plate puts on the downward pressure-plate-force of forming part one, and such part can cause two ends tilting, umbilicate defective mode under two groups of counter force.
Summary of the invention
For overcoming traditional shaping limitation of double blank drawing die, goal of the invention of the present invention is to provide a kind of time relay to solve de-material deformation device for double blank drawing die, to solve the drawn component de-material problem on deformation of non-enclosed binder.
For achieving the above object, mounting plate of the present invention, upper bolster, upper padding plate and molding concave die link together, and interior de-plate is slidably matched with molding concave die on upper bolster by patrix safety screw and spring fitting; Bottom plate, bottom seat pad, die shoe, lower plate link together, and forming convax mould is fixed in lower plate, and blank holder is arranged on die shoe by pneumatic jack bar and counterdie safety screw, and is slidably matched with forming convax mould.
Described pneumatic jack bar is connected with cylinder, the intake valve of cylinder connect hours relay, one end of the time relay connects air feed interface, the other end connects the counterdie switch module on die shoe, patrix switch module on upper bolster is relative with counterdie switch module, is realized that blank holder and interior de-plate are de-expects time irreversibility by the delay function of the time relay.
The time relay and cylinder link together by the present invention, control by the delay switch of the time relay time reaching control cylinder turnover gas.When mould moves downward matched moulds, molding concave die and blank holder move downward after plate compact, and interior de-plate starts compressing component, meanwhile, touch relay switch when upper bolster is descending, and during arrival bottom dead centre, cylinder loses heart, and forming parts is complete; During die sinking, the up disengaging relay switch of upper bolster, meanwhile, interior de-plate also departs from part gradually, and after plate de-in patrix departs from part completely, cylinder intake, by blank holder jack-up, part departs from from forming convax mould.Most critical of the present invention is in die sinking process, must wait for that interior de-plate departs from part completely to after part applying pressure, the air inlet of cylinder ability, otherwise the dual-pressure of counterdie blank holder and the interior de-plate of patrix can cause part gross distortion, and the time difference of centre realizes by the delay function of the time relay.
The present invention is compared with existing single-action drawing die, and forming parts profile is stablized, and can meet the requirement of part flatness, can the difficult problem of efficient solution closed binder drawing and moulding rear profile facial disfigurement and wrinkling injustice by no means.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, mounting plate 15, upper bolster 13, upper padding plate 14, molding concave die 11, interior de-plate 3, spring 1, patrix safety screw 2 form part of the upper die; Bottom plate 19, bottom seat pad 18, die shoe 17, lower plate 16, forming convax mould 4, blank holder 9, counterdie safety screw 5, pneumatic jack bar 7 and cylinder 6(cylinder number as required pressure size are determined) form part of the lower die.Mounting plate 15, upper bolster 13, upper padding plate 14 and molding concave die 11 link together, and interior de-plate 3 to be arranged on upper bolster 13 by patrix safety screw 2 and spring 1 and to be slidably matched with molding concave die 11; Bottom plate 19, bottom seat pad 18, die shoe 17, lower plate 16 link together, and forming convax mould 4 is fixed in lower plate 16, and blank holder 9 is arranged on die shoe 17 by pneumatic jack bar 7 and counterdie safety screw 5, and is slidably matched with forming convax mould 4.Pneumatic jack bar 7 is connected with cylinder 6, the intake valve of cylinder 6 connect hours relay 20, one end of the time relay 20 connects air feed interface, and the other end connects the counterdie switch module 8 on die shoe 17, and the patrix switch module 12 on upper bolster 13 is relative with counterdie switch module 8.In mould closing course, move downward arrival together after bottom dead center when interior de-plate 3, molding concave die 11 and blank holder 9 compress plate, patrix switch module 12 touches counterdie switch module 8, and time relay air outlet valve is opened, cylinder 6 loses heart, blank holder 9 pressure dump.In die sinking process, part of the upper die is up, and molding concave die 11 departs from plate at first, meanwhile, patrix switch module 12 departs from counterdie switch module 8, but due to the delay function of the time relay 20, now cylinder 6 can not at once air inlet, therefore blank holder 9 can not jack-up immediately; Part of the upper die is continued up, treats that interior de-plate 3 departs from plate, and after part of the upper die applies the complete removal of pressure to plate, the now time relay 20 INO, cylinder 6 is inflated, and pneumatic jack bar 7 is by blank holder 9 jack-up, and part blank 10 spins off from forming convax mould 4.
The course of work of the present invention is as follows:
1, the descending binder in part of the upper die process (as shown in Figure 1): interior de-plate 3, molding concave die 11 compress plate with blank holder 9;
2, matched moulds forming process (as shown in Figure 2): part of the upper die continues to move downward, forming convax mould 4 drives plate 10 to flow into molding concave die 11 die cavity, arrive after bottom dead center, patrix switch module 12 touches counterdie switch module 8, the air outlet valve of the time relay 20 is opened, cylinder 6 loses heart, blank holder 9 pressure dump, and forming parts is complete;
3, during die sinking, patrix takes off material process (as shown in Figure 3): part of the upper die is up, part of the lower die assembly transfixion, shaping recessed 11 depart from plate 10 at first, meanwhile, patrix switch module 12 departs from counterdie switch module 8, but due to the delay function of the time relay 20, now cylinder 6 can not at once air inlet, therefore blank holder 9 can not jack-up immediately.Part of the upper die is continued up, and interior de-plate 3 departs from plate 10, and part of the upper die applies the complete removal of pressure to plate 10;
4, blank holder takes off material process (as shown in Figure 4): the time relay 20 delay time arrives, the time relay 20 INO, and cylinder 6 is inflated, and pneumatic jack bar 7 is by blank holder 9 jack-up, and part blank 10 spins off from forming convax mould 4, and the whole course of work completes.Until the time relay 20 INO from patrix switch module 12 and counterdie switch module 8 depart from, the time difference therebetween can according to actual open time demand sets itself on the time relay 20.
