Wire cut electrical discharge machining device with convex tooth structure and wire electrode

Abstract

The invention relates to the technical field of wire electrodes, in particular to a wire cut electrical discharge machining device with a convex tooth structure and a wire electrode. The wire cut electrical discharge machining device comprises a shell, a fastening mechanism is mounted on the shell, the fastening mechanism is in threaded connection with the shell, a wire tightening mechanism is arranged in the shell, and the wire tightening mechanism is abutted against the fastening mechanism; and a telescopic mechanism is fixed to the bottom of the shell. A fifth gear rotates to drive a second bearing to rotate, the second bearing drives a conductive block to rotate, a conductive seat on the second bearing rotates synchronously, and a wire electrode body on the conductive seat rotates. According to the wire cut electrical discharge machining device with the convex tooth structure and the wire electrode, working liquid can be promoted to be brought into an interelectrode, meanwhile, the discharging of interelectrode corrosion removal products is accelerated, the interelectrode discharging condition is improved, the discharging rule is easier to control through regular protruding point crests on the surface of the wire electrode body with the convex tooth structure, and therefore the machining efficiency can be improved, and the surface quality can be improved; and the volume and the pitch of the chip containing space of the wire electrode body with the convex tooth structure can be controlled according to the rolling tooth shape size and the thread pitch.

Description

technical field [0001] The invention relates to the technical field of electrode wires, in particular to a wire electric discharge cutting device with a convex tooth structure and an electrode wire. Background technique [0002] Wire-cut EDM is a form of cutting workpieces with linear electrodes developed in the late 1950s on the basis of EDM, so it is called wire-cut EDM, or wire-cut for short. Wire EDM uses a long and thin metal wire as an electrode, and moves along the axis of the electrode wire at a certain speed, continuously entering and leaving the EDM area in the kerf. During processing, the positive electrode of the pulse power supply is connected to the workpiece, and the negative electrode is connected to the wire electrode, and liquid medium is injected between the wire electrode and the slit of the workpiece; at the same time, the workbench where the workpiece is installed is driven by the servo motor controlled by the control device according to the predetermin...

AI Technical Summary

Problems solved by technology

The use of glued electrode wire cannot clean the cutting groove of the workpiece during cutting, so that there are many burrs in the workpiece during the cutting process, making the surface of the cutting groove rough after cutting. For workpieces with high precision requirements, gluing The electrode wire cannot meet the precision cutting requirements
