Separate structure connects on lower module, and punch-pin front and rear sides are equipped with cast-in screw hole set, is connected with pressure by guide plate on the outside of punch-pin
Flange, blank holder upside are equipped with multiple pressure regulation pads, are equipped with multiple pneumatic jack pads on the downside of blank holder, pressure regulation pad and pneumatic jack pad are all along flanging
Avris distribution setting is enclosed, air cushion block is equipped on the outside of upper module, pier is equipped at left and right sides of lower module and extremely pads.
Further improvement lies in that: lower module front and rear sides are symmetrically arranged with material returned screw, and material returned screw, which is worn, to be connect in blank holder two
Side.
Further improvement lies in that: four side of blank holder is equipped with striker plate.
Further improvement lies in that: upper module front and rear sides are equipped with backplate.
Beneficial effects of the present invention: upper module, which pushes, drives blank holder flanging decline, and punch-pin and cavity plate carry out drawing and forming,
Make workpiece rapid shaping, effectively raises shaping efficiency；Punch-pin and lower module adopt a split structure, and punch-pin two sides are equipped with casting
Enter the placement of taking that formula screw hole inserting connects Lift crowbar for punch-pin, lower module is equipped with positioning key and fixes convenient for punch-pin positioning, subtracts
Lack materials'use, improves assembly efficiency and assembly accuracy, it is easy to repair, it improves service life；Air cushion block and pier are set
Dead pad reduces pressure, is buffered, prevents punching press is too fast from workpiece being caused to rupture；Setting material returned screw can quickly carry out the material returned,
Improve production efficiency；Striker plate is set, backgauge is carried out to workpiece, prevents workpiece variation from influencing production；It is anti-that backplate progress safety is set
Shield improves secure ram.
