Floating side hole punch die

Abstract

The invention belongs to a punch die and particularly relates to a floating side hole punch die. The floating side hole punch die comprises an upper die base, a lower die base, a first elastomer and a guide post, wherein the lower surface of the upper die base is connected with the first elastomer; the first elastomer is positioned in the guide post; the lower end of the guide post is arranged in the lower die base; a male die is fixed to the lower end of the upper die base; a workpiece groove is formed in the male die; the upper end of a workpiece is arranged in the workpiece groove; the workpiece can move up and down with an upper die and punch work is finished; the lower end of the workpiece is positioned in a gap between a female die and a discharging plate; the lower surface of the female die is arranged on the lower die base; the discharging plate is fixed to the upper surface of the female die, so that the machined position is convenient to position. The bottom of a shell part is relatively slightly punched, so that the machining efficiency is high, and the floating side hole punch die is safe and convenient to use.

Description

technical field [0001] The invention belongs to a stamping die, in particular to a floating side punching die. Background technique [0002] With the continuous development of society and the rapid advancement of science and technology, human beings have an increasing demand for various products, and all products need to be produced and processed through molds. In recent years, some shell parts have been widely used. In the traditional production process of these parts, due to the low accuracy of the shell parts, the center of the cavity is used as the reference when machining holes. The operation process is very cumbersome, and the efficiency of using drilling jigs is low and It is not easy to guarantee the precision of the part, and the traditional design method cannot meet the process requirements of the part. [0003] Chinese document CN103978244A discloses a drilling tool for automatic centering of shell parts. In this document, the longitudinal positioning plate and t...
