Description

A guide device for an electric spark punching machine

technical field

The utility model relates to the technical field of electric spark perforators, in particular to a guide device for an electric spark perforator.

Background technique

EDM punching machine is a kind of machine tool used to process precise small holes. Its working principle is to use a thin metal copper tube that continuously moves up and down vertically as an electrode to perform pulse spark discharge erosion and metal forming on the workpiece. Since the electrodes used are hollow copper rods, the small holes in the copper rods can be used for chip evacuation. In the prior art, since the electric spark perforator generally needs continuous operation, only relying on the small holes on the copper rod to discharge chips will inevitably cause the accumulation of chips and slag. Therefore, it is often necessary to remove the guide device for cleaning during continuous operation. Reinstalling it again wastes time and affects work efficiency. To this end, we propose a guide device for EDM punching machine.
