Three-plate high-speed progressive stamping die

Abstract

The present invention disclosed a three -board high -speed stamping mold, including: upper board, middle board, lower board, multiple other high structures, multiple spring pre -pressure structures, and multiple balls. There is a compressive plate, the lower template and the lower pad, and the upper plate and the middle plate are set with a fixed plate and upper pad. Due to the use of the mid -to -board and ball -beaded columns, the present invention can improve the accuracy of the stamped workpiece.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a three-plate high-speed progressive stamping die. Background technique [0002] In products in the fields of electronics, automobiles, motors, electrical appliances, instruments, meters, home appliances, and communications, most parts must be formed by molds, so molds have become important equipment for industrial production. In the metal cold stamping industry, high-speed progressive stamping dies have high production efficiency, high product precision, easy automation and mechanization, and are suitable for mass production needs, so they are widely used. [0003] However, the traditional high-speed progressive stamping die generally adopts a two-plate structure of the lower mold base and the upper mold base. This two-plate mold is suitable for workpieces that do not require high machining accuracy and have low mechanical strength. For workpieces with high precision requirements ...

AI Technical Summary

Problems solved by technology

For workpieces with high precision requirements and high mechanical strength, when using a two-plate mold, due to the insufficient mechanical strength of the mold itself, the mold will be slightly deformed during the stamping process, resulting in the precision of the processed workpieces not meeting the requirements
