Medium-speed wire cutting machine capable of fast threading

Abstract

The invention provides a medium-speed wire cutting machine capable of fast threading, and relates to the field of wire cutting machines. The machine comprises a machine body and a cutting wire; a first winding device is arranged on the rear side of the machine body; a second winding device is arranged on the front side of the machine body; one end of the cutting wire is connected with the first winding device, and the other end of the cutting wire is connected with the second winding device; and the machine body is further provided with a winding assembly used for transmission of the cutting wire. The first winding device is arranged on the rear side of the medium-speed wire cutting machine, the second winding device is arranged on the front side of the cutting piece, one end of the electrode wire is wound around the first winding device, the other end of the electrode wire is wound around the second winding device, and an operator enables the cutting wire to penetrate through a workpiece and then can directly wind around the second winding device, so that the winding time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of wire-cutting machines, in particular to a middle-feeding wire-cutting machine with fast threading. Background technique [0002] The wire cutting machine uses electrode wire (molybdenum wire, tungsten molybdenum wire, etc.) as the tool electrode. Under the action of pulse power supply, spark discharge is formed between the tool electrode and the workpiece, and the spark channel instantly generates a large amount of heat, which melts the surface of the workpiece. Even vaporization, so as to achieve the purpose of processing the workpiece. [0003] The wire cutting machine in the prior art has only one wire drum for retracting the electrode wire, and the wire drum is usually located behind the wire cutting machine. When the wire electrode needs to pass through the workpiece and be tied to the wire drum again, the operator must return to the wire cutting machine. At the rear of the machine, it will take a certain amo...

Problems solved by technology

[0003] The wire cutting machine in the prior art has only one wire drum for retracting the electrode wire, and the wire drum is usually located behind the wire cutting machine. When the wire electrode needs to pass through the workpiece and be tied to the wire drum again, the operator must return to the wire cutting machine. At the rear of the machine, it will take a certain amount of time for the operator to re-fix the electrode wire every time, resulting in low production efficiency
