Punching machine with function of automatically picking up

Abstract

The invention discloses a punching machine with a function of automatically picking up. The punching machine comprises a sliding block and a lower die, wherein the sliding block is connected with a crankshaft through a connecting rod; the lower die is arranged on a work tabletop; an upper die is arranged at the punch die part of the sliding block; a pull rod is vertically arranged at the rear end of the punching machine with the function of automatically picking up; one end of the pull rod is connected with the rear wall of the punching machine with the function of automatically picking up through a tension spring and is simultaneously connected with the upper end of the sliding block through a steel wire rope; an electromagnet is arranged at the other end of the pull rod; a stop lever for preventing the pull rod from translating towards the pull rod is arranged perpendicular to the pull rod; and a travel switch for controlling the electromagnet to be electrified is arranged on a sliding guide rail of the sliding block. The punching machine disclosed by the invention has the function of automatically picking up workpieces and wastes and improved production efficiency.

Description

technical field [0001] The invention belongs to mechanical processing devices, in particular to stamping machine tools. Background technique [0002] The design principle of the punching machine is to drive the slider through the crankshaft and the connecting rod, so that the slider makes a linear reciprocating motion, and then punches the workpiece. Generally, the slider die part of the punch press is provided with an upper die, and the working platform of the punch press is provided with a lower die, and the processing of the workpiece is completed through the cooperation of the upper die and the lower die. Since the inner cavity of the mold needs to be filled with fine oil during the stamping process, when the workpiece is stamped, it will be sucked on the inner cavity of the upper mold. In the prior art, tools are usually used to take out piece by piece, or the waste is blown away by air blowing. And the product is blown out, so the production efficiency is low, and the...

Since the inner cavity of the mold needs to be filled with fine oil during the stamping process, when the workpiece is stamped, it will be sucked on the inner cavity of the upper mold. In the prior art, tools are usually used to take out piece by piece, or the waste is blown away by air blowing. And the product is blown out, so the production efficiency is low, and the newly added air blowing equipment increases the equipment cost
