The gap of profile is 0.5mm-1.0mm.
The blank holder is made of resin material.
The pedestal is equipped with pin hole, and punch-pin is positioned by pin hole and pedestal.
1.73-1.75g/cm3 of density of the resin material of the cavity plate, punch-pin and blank holder, shore hardness be greater than 83,
Bending strength is greater than 80MPa, compression yield strength is greater than 85MPa, and heat distortion temperature is not less than 50 DEG C.
The utility model has the advantages that compared with prior art, the resin die manufacturing cycle of the utility model is short, non-environmental-pollution；Convex,
Cavity plate connect simply quick detachable replacement with pedestal；Pedestal has versatility.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure: 1, cavity plate, 2, punch-pin, 3, pedestal, 4, counter sink, 5, thread bush, 6, blank holder, 7, pin hole.
Specific embodiment
In conjunction with the preferred embodiment, to according to specific embodiment provided by the utility model, details are as follows:
It is detailed in attached drawing 1, present embodiment discloses a kind of automobile metal plate punching press resin dies, including cavity plate 1, punch-pin 2
With pedestal 3, the cavity plate and punch-pin are made of resin material, and punch-pin is connected by screw to pedestal, and it is heavy to be equipped on pedestal
Head bore 4, punch-pin are equipped with thread bush 5, and screw is connect by counter sink with thread bush, and cavity plate is connected by screw to pedestal,
Pedestal is equipped with counter sink, and cavity plate is equipped with thread bush, and screw is connect by counter sink with thread bush.
The preferred embodiment of the utility model is that the blank holder bottom surface is equipped with the pneumatic jack bar backing plate (figure using 45# steel plate
In do not show), punch-pin is placed in blank holder center, and the gap of blank holder and punch-pin die parting line profile is 0.5mm-1.0mm.The flanging
Circle is made of resin material.The effect control plate of blank holder inhibits material to flow during drawing and forming, and plate is made to exist
Uniform feeding in flow process avoids the problem that corrugation cracking occurs in forming process in plate, causes part rejection.
The preferred embodiment of the utility model is that the pedestal is equipped with pin hole 7, and punch-pin is fixed by pin hole and pedestal
Position.
