Structure of novel piercing punch

Abstract

The invention relates to a novel structure of a piercing punch, which is composed of a handle, a punching head and a ball socket. The piercing punch is provided with the handle and the punching head; the ball socket is formed on the low plane of the punching head; and the maximum diameter of the ball socket is equal to the top circle diameter of the punching head. In the structure of the novel piercing punch, by using the scheme, the blade becomes quite sharp; and a large press machine is not needed for piercing a large hole or a thick plate; therefore, the novel piercing punch has the advantages of low investment in punching production and low production cost.

Description

technical field [0001] The invention relates to a structure of a punching punch, in particular to a structure of a novel punching punch, and belongs to the technical field of punching dies. Background technique [0002] At present, in the structure of the punching die, the punching die is generally composed of a die handle and a punch. The working surface of the punch, that is, the shearing surface, is a plane type. Although this type of plane type has a simple structure, the process However, due to the plane type, the blade is not sharp enough. In order to punch larger holes or thicker sheets, a larger press must be used. It requires a larger investment in stamping production, and the production cost is higher. Contents of the invention [0003] The purpose of the present invention is to provide a new structure of the punching punch, which overcomes the reason that the existing punching punch must use a larger press when punching larger holes or thicker sheets due to the...
