Punching die with safety protection function

Abstract

The invention relates to a stamping die with a safety protection function. The stamping die comprises an upper die holder and a lower die holder which are opposite, wherein a convex die is arranged on the upper die holder, a concave die is arranged on the lower die holder, and a concave die hole matched with the convex die is formed in the concave die. The stamping die is characterized in that an I-shaped upright guide pillar is fixed on the lower die holder; a square guide sleeve in sliding fit with the upright guide pillar is arranged on the upper die holder; the side surface of a wing plate of the upright guide pillar is in sliding fit with a pair of opposite inner sides of the square guide sleeve; a lining brake connected with an external braking line is arranged on a web plate at the lower end of the upright guide pillar; when the square guide sleeve is positioned at the lining brake at the lower end of the upright guide pillar, the lining brake extends out to be attached and locked with another one pair of opposite inner sides of the square guide sleeve. A detection device for detecting foreign matters in a down stamping stroke of the convex die is arranged on the convex die; the output end of the detection device is connected with the input end of a control device; the output end of the control device is connected with the control end of the braking line.

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...
