, it is provided with guide cutting edge passage on the cavity plate；
Correcting plate, the correcting plate installation is simultaneously spacing on die shoe, and positioned at the upside of the cavity plate, the correcting plate
On be provided with punch-pin correcting passage, the axis of the punch-pin correcting passage, the axis of the guide cutting edge passage and the hole
Axis coaxle is set；
Impact block；
Punch-pin, the punch-pin are placed in the punch-pin correcting passage, and the punch-pin under the strike of impact block with
Cavity plate coordinates the blank that shearing is positioned on blank placement position, then passes sequentially through described lead together with the shearing material shear off
Expect cutting edge passage and the hole.
Positioned on die shoe further for convenient and change cavity plate and correcting plate, the cavity plate and the correcting plate are equal
For cross-shaped configuration, be provided with the die shoe match with cavity plate and correcting plate merges be in cross-shaped configuration groove, it is described
In cavity plate insertion groove, the correcting plate is also embedded in groove.
Further for blank is positioned on cavity plate, it is to be arranged on cavity plate and can be embedded in blank that the blank, which places position,
Bar-shaped trough.
Further for the blank that bar-shaped trough can be made to adapt to different length, material blocking block is connected with the cavity plate, it is described
Material blocking block is located at the end of bar-shaped trough.
Further for facilitating punch-pin to pass through guide passage, the bottom of the punch-pin is cylindrical structural, described convex
The top of mould is truncated cone structure.
After employing above-mentioned technical proposal, blank is placed on cavity plate, is positioned by cavity plate and material blocking block, when punch press carries out punching press
When, sliding block is descending with impact block, impact block strike punch-pin, under the correcting of punch-pin correcting passage of the punch-pin on correcting plate with it is recessed
Mould is sheared to blank together, goes out hole, and after punching, punch-pin is fallen into together with waste material in the pallet under working plate, punching press
Work is pressed from both sides out with pliers, then is put into the punch-pin correcting passage of correcting plate, carries out punching press next time, the punching die punching press
Action is safe and reliable, and product size precision high energy meets production requirement, and the punching die is easily manufactured, quick and cost is low, punching
Punch die uses general upper bolster, and cavity plate, the semi-finished product blank of correcting plate are also general, are drilled out as long as the used time is matched somebody with somebody with drilling machine
Cavity plate and punch-pin correcting passage can (cavity plate will be also heat-treated), punch-pin and material blocking block etc. make serial finished product in advance.So both
Shorten the mould production cycle, reduce number of molds again, while and can meets the quality requirement of part, substantially reduces mould production
Cost and raising manufacturing schedule；The punching die can Fast Installation, punching die is in use, the die shoe of punching die is not required to use
Pressing plate is pushed down, and to be fixed on working plate, is placed directly on working plate, and impact block (band die shank) is arranged on punch press and slided
On block, slide block down hits punch-pin with impact block, and punch-pin is under the accurate guiding of punch-pin correcting passage and cavity plate collective effect
Hole is gone out on billot.
