Stamping die with safety protection function

Abstract

The invention relates to a stamping die with a safety protection function and belongs to the technical field of metal stamping. The stamping die with the safety protection function comprises an upper die holder and a lower die holder arranged oppositely, the upper die holder is provided with a convex die, the lower die holder is provided with a concave die, a concave die groove matched with the convex die is formed in the concave die, the concave die is provided with a press plate used for stamping a press edge of a forming part, a transverse H-shaped upright guide post is fixed on the lower die holder, a square guide sleeve having sliding fit with the upright guide post is arranged on the upper die holder, the lateral surface of a wing plate of the upright guide post is in sliding fit with one pair of opposite internal lateral surfaces of the square guide sleeve, a lining brake connected with an external braking pipeline is arranged on a web at the lower end of the upright guide post, when the square guide sleeve is located at the lining brake at the lower end of the upright guide post, the lining brake extends out to fit with the other pair of opposite lateral surfaces of the square guide sleeve and lock the same. The stamping die with the safety protection function is capable of urgently braking a micro-stamping machine under a dangerous situation so as to protect the personnel security.

Description

[0001] This application is a divisional application. The invention-creation name of the original application: stamping die with safety protection function, application number: 201310266387.0, application date: 2013-06-28. technical field [0002] The invention relates to a die, which belongs to the technical field of metal stamping. Background technique [0003] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The application fields of sheet metal parts are extremely wide, and they penetrate into all aspects of the manufacturing industry. Sheet metal forming is mainly realized by stamping dies. Using the stamping process, it has a series of advantages such as high precision, high efficiency, good quality, cost saving, material and energy saving. [0004] At present, many enterprises still use the simple manual operation method when using the stamping method to process and produce, that is, to dir...
