Mould capable of protecting personnel safety and working method of mould

Abstract

The invention relates to a mould capable of protecting personnel safety and a working method of the mould, and belongs to the technical field of metal stamping. The punching mould comprises an upper mould base, a lower mould base, a male mould, a female mould, a vertical guide post and a square guide sleeve, a female mould hole is formed in the female mould, the side face of a wing plate of the vertical guide post is in sliding fit with a pair of opposite inner side faces of the square guide sleeve, a brake connected with an external brake pipeline is arranged at the lower end of the vertical guide post and comprises a pair of opposite brake shoes, one end of each brake shoe is hinged onto a web plate of the vertical guide post, the other ends of the brake shoes are in rolling connection with driving cams, an inclined surface and a friction plate are arranged on each brake shoe, each inclined surface is inclined to the other end of the corresponding brake shoe, each friction plate is arranged on the corresponding inclined surface, the driving cams drive the brake shoes to rotate and enable the friction plates to be fitted and locked with another pair of opposite inner side faces of the square guide sleeve when the square guide sleeve is positioned at the brake at the lower end of the vertical guide post. The punching mould has the advantages that a miniature gouging machine is emergently braked under dangerous conditions, and further personnel safety is protected.

Description

[0001] This application is a divisional application. The invention-creation name of the original application: punching die with braking function, application number: 201310266209.8, 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] The blanking process 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 punching dies. The blanking process 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 blanking method to process and produce, that is, to directly load and take...
