Blanking die capable of achieving emergency braking and safety protection and operating method thereof

Abstract

The invention relates to a blanking die with the safety protection function. The blanking die with the safety protection function comprises an upper die base and a lower die base, wherein the upper die base and the lower die base are oppositely arranged, a male die is arranged on the upper die base, a female die is arranged on the lower die base, and a female die hole which is matched with the male die is formed in the female die. The blanking die with the safety protection function is characterized in that an I-shaped vertical guide column is fixed to the lower die base, a square guide sleeve which is in sliding fit with the vertical guide column is arranged on the upper die base, the side faces of a wing plate of the vertical guide column are in sliding fit with a pair of opposite inner side faces of the square guide sleeve, a lining valve which is connected with an external braking pipeline is arranged on a web at the lower end of the vertical guide column, and when the square guide sleeve is located at the position of the lining valve at the lower end of the vertical guide column, the lining valve stretches out and is attached and locked to the other pair of opposite inner side faces of the square guide sleeve. A detection device used for detecting foreign matter in downward blanking traveling distance of the male die is arranged on the male die, the output end of the detection device is connected with the input end of the control device, and the output end of the control device is connected with the control end of the braking pipeline.

Description

[0001] This application is a divisional application. The invention-creation name of the original application: punching die with safety protection function, application number: 201310266388.5, 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 loa...
