Stamping die capable of efficiently stamping workpieces and automatically popping up

Abstract

The invention relates to the field of stamping dies, and discloses a stamping die capable of efficiently stamping workpieces and automatically popping up. The lower end of a vertical rod is rotationally connected with a swing rod, the lower end of the back face of the swing rod is rotationally connected with a cylinder, and the outer side of the cylinder is movably connected with a clamping rod; a rotating rod is rotationally connected to the side, away from the cylinder, of the front face of the clamping rod, a push rod is in sliding connection to the middle of the opposite end on the side face of the rotating rod, the other end of the push rod is movably connected with a first spring, and the lower end of the opposite side of the rotating rod is fixedly connected with the first spring. A lifting shaft is started and drives an upper die to lift, when the upper die descends to the surface of a workpiece, the workpiece is stamped, an elastic air bag at the lower end of an air guide frame extrudes the top of a bearing rod, air in the elastic air bag enters a connecting frame to enable a piston plate and a vertical rod to descend, the vertical rod descends to push the swing rod to rotate to drive the cylinder to extrude the clamping rod, and the clamping rod horizontally moves to drive the rotating rod to rotate; and the push rod extrudes a rectangular base to enable the rectangular base to drive the upper die to descend for the second time, secondary stamping is conducted on the workpiece, and the purpose of avoiding blind holes when the thick workpiece is machined is achieved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for automatic ejection of high-efficiency stamping workpieces. Background technique [0002] Stamping die is a special process equipment in cold stamping processing, which is used to process material workpieces into target shape parts. Usually, during processing, the mold is used to apply pressure to the workpiece to make it plastically deform or separate, but sometimes it will be deformed during processing. There are cases where the part does not come free from the material, and the part that comes out sometimes gets stuck in the mold. [0003] When stamping a thicker mold, sometimes the strength is not enough so that the parts that need to be separated cannot be separated from the raw material, resulting in blind holes, and sometimes the finished parts will be stuck inside the mold due to high friction after they are separated from the raw material , it is...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency stamping die that automatically ejects the workpiece, which has the advantages of avoiding blind holes when processing thicker workpieces and automatically ejecting the workpiece after processing, and solves the problem of blind holes that are prone to occur when processing thicker workpieces. hole, the problem that the workpiece is easily stuck in the mold after stamping
