Reusable Die Punch and Reuse Method

Abstract

The invention discloses a reusable die punch and a reuse method, aiming to solve the problem that the existing die punch cannot be reused, and when the front part of the punch is worn or broken, it can only be scrapped, resulting in waste. Insufficient stamping cost has been increased. The invention comprises a punch body, the rear end of the punch body is fixedly connected to the punch base, a number of gasket installation holes are arranged on the punch base, a quantitative groove is arranged on the rear side of the punch base, and a quantitative plate is installed in the quantitative groove. A push sleeve is movable sleeved on the punch body, several push rods are uniformly connected between the rear end of the push sleeve and the quantitative plate, and a return spring is arranged between the rear end of the push sleeve and the punch base, and the push sleeve An adjustment sleeve is sleeved between the front end of the pipe and the punch body, and a positioning mechanism is provided on the outer wall of the adjustment sleeve, and several positioning holes matching the positioning mechanism are arranged on the pushing sleeve axially, and the positioning mechanism is connected and positioned at the most When adjusting the positioning hole at the front end, the front end of the sleeve is flush with the front end of the punch body.

Description

technical field [0001] The present invention relates to a die punch, more particularly, it relates to a reusable die punch. Background technique [0002] The punch is a part used on the cold stamping die, which is used to stamp and punch the workpiece. Its material is very hard, its strength is high, and its workmanship must be fine, so it is expensive. The use of die punches in the machinery industry is very common, but the front of the punch is easy to wear or even break after being used for a period of time, resulting in the scrapping of the punch and waste, and these punches are relatively expensive, and the direct scrapping has greatly increased Stamping costs. [0003] Chinese Patent Publication No. CN103464575A discloses a wear-resistant die punch, which includes a punch, a die, a cone and a guide sleeve. The bit sleeve is installed in the die. The friction of the punch is reduced through the use of the guide sleeve, thereby reducing the wear of the punch and prolo...

Problems solved by technology

[0004] The present invention overcomes the problem that the existing die punch cannot be reused. When the front part of the punch is worn or broken, it can only be scrapped, which causes waste and increases the stamping cost, and provides a reusable die punch. Head and reuse method, the mold punch can be reused, and it can be used 2-3 times after the front part of the punch is worn or broken, which will not cause waste, greatly reduce the stamping cost, and bring more benefits to the enterprise. economic benefits
