Spark erosion drilling machine

Abstract

The invention discloses a spark erosion drilling machine. The spark erosion drilling machine comprises a base. A first sliding rail is mounted on one side of the base. A second sliding rail is mountedon one side, close to the first sliding rail, of the base. A controller is mounted at the inner bottom of the base. A workbench is mounted at the top of the base. A fixing plate is mounted on one side of the workbench. A lifting platform is mounted on one side of the fixing plate. A metal hose is fixedly connected to one side of the fixing plate through bolts. A universal ball seat is mounted atone end of the metal hose. The spark erosion drilling machine has the advantages that through the arrangement of the first sliding rail, the second sliding rail, a straight tube, a high-pressure fan and an air exhaust plate, the surface of a to-be-processed workpiece is kept undamaged, heat dissipation of the workbench is accelerated, and a user can mount and demount the workpiece conveniently; through the arrangement of the metal hose, a universal ball, the universal ball seat and an eye-protecting plate, movement of the eye-protecting plate is facilitated, and accordingly, the user can adjust the placement position of the eye-protecting plate conveniently.

Description

technical field [0001] The invention belongs to the technical field of electric spark piercing machines, and in particular relates to an electric spark piercing machine. Background technique [0002] EDM punching machine refers to the EDM machine tool that uses the principle of EDM to process holes with a size less than 5mm. It is used to process small and medium-sized dies. Its processing feature is not limited by the hardness of metal materials. The template can be quenched first and then used This machine processes the required hole pattern to ensure the quality and improve the service life. The tool electrode materials are steel, cast iron and copper. [0003] In the Chinese patent No. 201721105800.5, the patent name is a new type of electric spark piercer. It is mentioned that the position of the glass plate is firmly restricted by the upper limit block to protect the safety of the user. Turning the upper body can rotate freely at 360 degrees, but the above-mentioned n...
