A sheet metal stamping die based on flat demoulding

Abstract

The invention discloses a sheet metal stamping die based on flat demoulding. Its structure includes an upper die, a die column, and a lower die. structure, the stamping structure is composed of top plate, middle plate, bottom plate and plate column, the top plate, middle plate and plate column are welded, the middle plate and the bottom plate are matched, and the bottom plate is equipped with a stripping device. The size is transmitted through the outer structure or the inner circle structure, and the inner square structure can be adjusted. The outer square frame can be adjusted to move on the outer square cone to realize the size reduction of the adjustable outer square frame. The inner square cone can be adjusted. Moving on the circle realizes the reduction of the diameter of the telescopic ring; then, when the mold is demoulded, the mold and the plate will not fit closely, and the local upward movement of the plate will not occur when the mold is demoulded, and the micro deformation of the plate will not occur.

Description

technical field [0001] The invention relates to the field of molds, in particular to a sheet metal stamping mold based on flat demoulding. Background technique [0002] Metal stamping is the manufacturing process of using a metal stamping die or series of metal stamping dies to form sheet metal into workpieces with three-dimensional dimensional shapes; metal stamping can form sheet metal very efficiently. Metal stamping dies are mounted on a press, and each stroke of the press forms a workpiece. [0003] Prior Art The traditional sheet metal stamping die uses the upper and lower dies under the action of the press to realize the punching process using the upper and lower dies to realize the cutting of the sheet. How to improve the quality of the sheet during this process is an issue that needs to be improved in the prior art Places, such as: when the plate is demoulded after cutting and stamping, because the mold exerts pressure on the plate during stamping, the mold and the...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, to provide a sheet metal stamping die based on flat demoulding, to solve the problem that the traditional sheet metal stamping die uses the upper and lower dies under the action of the press to realize the stamping of the upper and lower dies. The cutting process realizes the cutting of the plate. How to improve the quality of the plate in this process is a place that needs to be improved in the existing technology. Due to the tight fit between the mold and the plate, the partial upward movement of the plate is caused when the mold is demoulded, resulting in the problem of slight deformation of the plate
