Magnetic control type metal plate two-surface punching machining device

Abstract

The invention relates to a magnetically controlled double-sided punching device for sheet metal, which includes an upper punching driving device, an upper template and an upper punching head, and a lower punching driving device located below the upper punching head. The template and the lower punching head; a clamping device is provided between the upper punching head and the lower punching head, and the clamping device includes a symmetrically arranged clamping block. The inner side of the clamping block is provided with a clamping groove, one of which clamps The outer side of the holding block is fixed to the cylinder; the lower surface of the upper template and the upper surface of the lower template are respectively equipped with magnetic switches, and the lower template is equipped with a magnetic head, and the magnetic switch detects the distance between the upper template and the lower template through the induction of the magnetic head. The invention adopts double-sided simultaneous punching to realize the processing of holes, realizes punching of thicker plates, and has small punching resistance and high punching efficiency; a magnetic control induction detection structure is set to detect the safety distance in real time and improve processing security.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a sheet metal punching machine. Background technique [0002] Existing punching devices or punching machines all include a frame, a bottom mold fixed on the frame, an upper template that moves up and down relative to the frame, and a punch corresponding to the bottom mold is fixed on the upper template. , the upper template is connected with the oil cylinder or cylinder that drives it to move up and down. Driven by the oil cylinder or air cylinder, the upper template drives the punch to move up and down relative to the bottom die, so as to punch out the required holes on the workpiece between the punch and the bottom die. The disadvantages of the above-mentioned punching device or punching machine are: only the thin plate can be punched, and there are many burrs on the edge of the hole after punching, and the hole processing quality is not high; after punching, th...
