Background technology

General dual binder drawing mold structure is all to adopt blank holder and the first binder of molding concave die, and while continuing to move downward, punch contacts with plate, drives plate to flow into concave die cavity.Arrive that after bottom dead center press ram is up, counterdie air cushion pressure is by de-blank holder jack-up material simultaneously.But this structure is bad for some small-sized non-enclosed binders and the irregular stamping parts molding effect of profile, easily occur that forming surface central plane degree is bad, and because of the unstable unsettled situation of drawing and moulding profile that there will be of air cushion pressure size.In order to reach the requirement of part flatness, must increase material pressing device in Central of the parts plane, just there is upper and lower dual binder in mould like this, in the time of die sinking, blank holder upwards jack-up puts on de-material power of forming part, in patrix, de-plate puts on downward pressure-plate-force of forming part, and part can cause two ends perk, umbilicate defective mode under two groups of adverse effect power like this.

Summary of the invention

For overcoming traditional dual binder drawing die moulding limitation, goal of the invention of the present utility model is to provide a kind of time relay to solve de-material deformation device for dual binder drawing die, to solve the de-material of the drawn component problem on deformation of non-enclosed binder.

For achieving the above object, mounting plate of the present utility model, upper bolster, upper padding plate and molding concave die link together, and interior de-plate is slidably matched on upper bolster and with molding concave die 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, realizes blank holder and the de-material of interior de-plate asynchronism(-nization) step by the delay function of the time relay.

The utility model links together the time relay and cylinder, reaches the time of control cylinder turnover gas by the delay switch control of the time relay.In the time that mould moves downward matched moulds, molding concave die and blank holder will move downward after plate compact, and interior de-plate starts compressing component, meanwhile, touch relay switch when upper bolster is descending, and while arriving bottom dead centre, cylinder loses heart, and forming parts is complete; When die sinking, the up disengaging relay switch of upper bolster, meanwhile, interior de-plate also departs from part gradually, depart from completely after part until de-plate in patrix, cylinder intake, by blank holder jack-up, part departs from from forming convax mould.The utility model most critical is in die sinking process, in must waiting for, de-plate departs from after part do not exert pressure to part completely, the air inlet of cylinder ability, otherwise the dual-pressure of de-plate can cause part gross distortion in counterdie blank holder and patrix, and the middle time difference realizes by the delay function of the time relay.

The utility model is compared with existing single-action drawing die, and forming parts profile is stable, can meet the requirement of part flatness, can efficient solution a difficult problem for profile distortion and wrinkling injustice after closed binder drawing and moulding by no means.
