Linear cutting machine

Abstract

The invention relates to a linear cutting machine, comprising a base, a wire storage barrel, a coil holder, and a wire electrode, wherein the wire electrode achieves wire-driving and tensioning of the wire electrode in coordination of the wire storage barrel and a guide wheel; wire electrode tension measurement devices are arranged on an upper bracket arm and a lower bracket arm of the coil holder; the tension measurement device comprises two guide wheels, a regulating wheel, a regulating rod and a sensing element; the two guide wheels are arranged at two sides of the regulating rod, and symmetrical relative to the center shaft of the regulating rod; the regulating rod is a hydraulic rod; the position of the regulating rod is controlled by the sensing element; the positions of the upper bracket arm and the lower bracket arm of the coil holder can be adjusted.

Description

technical field [0001] The invention relates to a wire cutting machine tool. Background technique [0002] Wire cutting machine tools are widely used in the mechanical parts processing industry. The principle is that the workpiece moves relative to the electrode wire according to a predetermined control trajectory. One pole of the pulse power supply is connected to the workpiece, and the other pole is connected to the electrode wire. Always maintain a certain discharge gap between the workpiece and the electrode wire and spray the working fluid, the spark discharge between the electrodes will corrode a certain gap, and the continuous pulse discharge will cut out the required shape and size of the workpiece. [0003] During the working process, the electrode wire is in a tensioned state to ensure that the surface texture and roughness of the processed workpiece meet the requirements. However, if the electrode wire is too tight, it will break the wire. In the process of ope...

However, if the electrode wire is too tight, it will break the wire

In the process of operation, there is also a phenomenon that the tension force of the electrode wire changes suddenly, which has a great impact on the surface roughness and texture of the processed workpiece.
