Improvement process for punch die

Abstract

The invention discloses an improvement process for a punch die. A punch tool is movably mounted in a mounting groove in the bottom of a substrate through a layer of the substrate with the mounting groove, the position of the punch tool is limited through fastening bolts, the surfaces, located between a top plate and a die holder, of guide columns and surfaces, located between the die holder and apressing plate, of the guide columns are sleeved with damping springs correspondingly, the guiding function on the punch die is achieved only through the four guide columns, and the damping effect isimproved; and condensation coils are embedded in the pressing plate, the punch tool is cooled by cold water circulation through the condensation coils, meanwhile, damping rubber pads are pasted to thebottom of the pressing plate, and sponge pads attached to the punch tool are pasted to the inner sides of the damping rubber pads. The punch die is simple and reasonable in structural design, convenient to dismount and mount and good in damping effect, achieves the radiating effect effectively, is capable of cleaning chips conveniently, safe, stable, diversified in function, good in punching effect, wide in application range and capable of being applied and popularized easily.

Description

Technical field [0001] The invention belongs to the technical field of punching dies, and specifically relates to an improved process for punching dies. Background technique [0002] Punching die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. However, the existing punching die is inconvenient to disassemble and assemble. When used continuously for a long time, the punching tool will generate high temperature, which accelerates the wear of the tool, and the punching tool is easy to be stained with waste chips, which causes burrs or cut wear in material processing. , Affecting the processing quality, the existing punchi...

AI Technical Summary

Problems solved by technology

However, the existing punching dies are inconvenient to disassemble and assemble. When used continuously for a long time, the punching tool will generate high temperature, which will accelerate the wear of the tool, and the punching tool is easy to be stained with waste, which leads to burrs or incision wear in material processing. , affecting the processing quality, the existing punching dies are prone to shaking between the parts after a long time of use, and the shock absorption capacity is weak, which is not conducive to extensive promotion and popularization
