Sloping shoulder type male die

Abstract

The invention relates to the field of stamping dies, in particular to a male die structure locked by a steel ball. The male die structure comprises a male die and a fixing block used for fixing the male die, the male die is fixed to a die plate through a positioning pin, a concave hole is formed in the side wall, matched with the fixing block, of the male die and is internally provided with the steel ball used for locking the male die, and a spring used for butting and pressing the steel ball and a bolt used for limiting the spring are arranged in the fixing block. In the process of installing the male die structure, the male die is installed in an installing hole of the fixing block and then positioned through the positioning pin, the steel ball is put in the concave hole from the installing hole of the fixing block and then butted and pressed through the spring, and at last the spring is limited through the bolt. When disassembled, the male die can be disassembled conveniently just by disassembling the bolt and the spring. The male die is simple in structure and convenient and fast to assemble and disassemble, the efficiency of stamping is greatly improved, and the maintenance cost of the male die is saved.

Description

technical field [0001] The invention relates to the field of punching dies, in particular to a slanted shoulder punch. Background technique [0002] In the prior art, when punching a thick plate, the head of the punch will be damaged due to stress concentration and tensile impact force on the head of the punch at the moment of punching. Generally, in order to increase the strength of punch head and punch rod for thick plate punching and prevent damage to the punch head, it is necessary to increase the radius of the transition arc at the transition connection between the punch head and the punch rod, but If the radius is too large, the size of the punch head will be too large, the installation space of the punch will be increased, and the cost of the mold will be increased. Therefore, it is impossible to excessively expand the filter radius. Contents of the invention [0003] The invention aims at the problems existing in the prior art, and provides a simple and compact st...
