A sheet metal stamping die with a replaceable punch

Abstract

The invention discloses a metal plate stamping die with a punch capable of being replaced. An installing frame is included, and a cylinder is connected to the top end of the installing frame; a piston rod is of the cylinder is connected with a push rod; the push rod penetrates through the top end of the installing frame, and extends into the installing frame to be connected with a push plate; the middle position of the bottom end of the push plate is connected with an upper mold; the middle position of the bottom end of the upper mold is provided with a cylindrical groove; the top end inner wall of the groove is connected with first springs of the same structure in the diameter direction of the groove, and the inner wall of the groove is connected with four baffles arranged in an annular array manner; the baffles are provided with through holes; and the punch is arranged in the groove, and the top end of the punch is in contact with the first springs. The metal plate stamping die with the punch capable of being replaced is novel in structure, the punch can be fast replaced and installed according to the machining requirement, it can be guaranteed that the situation that a metal plate component is attached to the punch and cannot be taken down easily is avoided, the metal plate machining time is effectively saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a sheet metal stamping die with replaceable punches. Background technique [0002] Stamping 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. The materials for making stamping dies include steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low melting point alloy, aluminum bronze, polymer material and so on. Most of the materials for manufacturing stamping dies are mainly steel. The types of commonly used die working parts materials are: carbon tool steel, low alloy tool steel, high carbon high chrom...

AI Technical Summary

Problems solved by technology

[0003] During the use of sheet metal stamping dies, because the required sheet metal shapes are different, it is often necessary to replace the punches of the stamping dies, but the replacement of the punches is complicated, so a lot of time will be wasted, and the stamping dies will be used after stamping. , the punch of the upper die will cause the required sheet metal to adhere to the punch due to the excessive impact force, and it is not easy to remove. Therefore, in order to solve such problems, we propose a sheet metal stamping that can replace the punch mold
