Metal plate two-sided punching device

Abstract

The invention relates to a metal plate two-sided punching device which comprises an upper punching drive device, an upper die plate and an upper punching head. The metal plate two-sided punching device further comprises a lower punching drive device located below the upper punching head, a lower die plate and a lower punching head. A clamping device is arranged between the upper punching head and the lower punching head. The clamping device comprises clamping blocks symmetrically arranged. The inner side of each clamping block is provided with a clamping groove. The outer side of one clamping block is fixedly connected with an air cylinder. The lower surface of the upper die plate and the upper surface of the lower die plate are respectively provided with one proximity switch. According to the metal plate two-sided punching device, hole machining is achieved by punching the two sides at the same time, thicker plates can be punched, the punching resistance is small and the punching efficiency is high; burrs on the hole edges are avoided in the two-sided punching process, a machined work-piece does not deform, and the quality is high; automatic control is achieved by adopting a controller, the motion is accurate, and the labor intensity is low.

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...
