Fusing device for medium-speed wire cut electrical discharge machining tool

Abstract

The invention discloses a fusing device for a medium-speed wire cut electrical discharge machining tool. The fuse device comprises a metal plate box, a fusing bar, a fusing bar fixing shaft, a fusing electricity feed wire, a fusing electricity feed wire fixing bolt, a ceramic insulating bar and a ceramic insulating bar fixing seat. By means of the fusing device for the medium-speed wire cut electrical discharge machining tool, an electrode wire is fused through the fusing bar, the fusing point of the electrode wire is melted under the high-temperature condition, a fracture becomes conical under the effect of tension, the diameter of an end becomes smaller, the fusing point of the electrode wire is cooled in air, and heat treatment of the electrode wire is completed, so that the fusing point of the electrode wire can be more straight and harder and can penetrate an eye film more easily, operation is simple, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to a fusing device for a wire cutting machine tool in an electric spark. Background technique [0002] In order to better ensure the processing accuracy and surface roughness of the existing wire-cutting wire-cutting machine tools, an eye mask (diameter of the eye film hole is 0.192mm) is set on the water spray plate of the upper and lower wire racks to ensure that the wire electrode is in the process of processing. It is not easy to shake in the center, and the electrode wire (diameter 0.18mm) needs to pass through the upper and lower eye membranes. [0003] The traditional method is to cut the electrode wire with scissors, the fracture is easy to deform and the diameter becomes larger, because the diameter of the eye membrane hole is 0.012mm different from the diameter of the electrode wire, it is difficult for the deformed electrode wire to pass through the eye membrane, and it is very difficult to operate. trouble.

[0003] The traditional method is to cut the electrode wire with scissors. The fracture is easy to deform and the diameter becomes larger. Since the diameter of the eye membrane hole is 0.012mm different from the diameter of the electrode wire, it is difficult for the deformed electrode wire to pass through the eye membrane, which is very difficult to operate. trouble
