Electric spark wire cutting machine

Abstract

The invention discloses an electric spark wire cutting machine. According to the technical scheme, the electric spark wire cutting machine is characterized by comprising a workpiece installing base for installing a workpiece, a base, a sliding base which is in horizontal sliding connection with the base, and a cutting wire arranged on the sliding base and used for cutting the workpiece. The sliding base is provided with a drive mechanism for driving a cutting wire to move and achieving cutting of the workpiece, and a bevel cutting mechanism for enabling the cutting wire to be in the inclined state and achieving bevel cutting. The purpose that the cutting wire is inclined within the space range and the workpeice is cut obliquely is achieved. Meanwhile, the problem that equipment is abradeddue to the fact that the cutting wire is pulled hard is effectively avoided.

Description

technical field [0001] The invention relates to the field of electric discharge cutting, in particular to a wire electric discharge cutting machine. Background technique [0002] Wire EDM (Wire Elect1rical Discharge Machining referred to as WEDM), which belongs to the category of electrical processing, was discovered by the former Soviet Union Lazalianke couple when they studied the phenomenon and causes of the damage of switch contacts by spark discharge corrosion, and found that the instantaneous high temperature of EDM can The local metal is melted, oxidized and corroded, thus creating and inventing the electric discharge machining method. [0003] Existing EDM cutting machines generally cut the workpiece with the cutting line in a vertical state. Generally, they can only cut the vertical surface and cannot cut the inclined plane normally, or cut the cutting line in an inclined state by strongly pulling the cutting line. However, when the cutting line When pulling strong...

AI Technical Summary

Problems solved by technology

[0003] Existing electric spark cutting machines generally cut the workpiece through the vertical state of the cutting line, generally can only cut the vertical surface, and cannot cut the inclined surface normally, or cut the cutting line in an inclined state by strongly pulling the cutting line, but when the cutting line When pulling strongly, it is easy to cause the cutting line and the guide wheel to separate, or the cutting line and the guide wheel move eccentrically, the friction force increases, and it is easy to cause equipment failure
