Description

technical field [0001] The invention relates to the technical field of intermediate wire cutting, in particular to a high-precision intermediate wire cutting device. Background technique [0002] Wire cutting machine tool is a kind of CNC machine tool that processes electrical conductors by electric discharge through reciprocating molybdenum wire. During the processing, molybdenum wire reciprocates. The wire-feeding mechanism of the wire-cutting machine has a direct impact on the surface roughness and size of the processed workpiece. It discharges on the molybdenum wire, and the molybdenum wire is affected by its own tension during the wire-feeding process, so the molybdenum wire will relax, which directly affects the molybdenum wire. The tension and tensile strength of the molybdenum wire, and because the molybdenum wire becomes loose and the tension becomes smaller, the tension is uneven, most equipment monitors the tension of the molybdenum wire through non-contact, so th...

The wire-feeding mechanism of the wire-cutting machine has a direct impact on the surface roughness and size of the processed workpiece. It discharges on the molybdenum wire, and the molybdenum wire is affected by its own tension during the wire-feeding process, so the molybdenum wire will relax, which directly affects the molybdenum wire. The tension and tensile strength of the molybdenum wire, and because the molybdenum wire becomes loose and the tension becomes smaller, the tension is uneven, most equipment monitors the tension of the molybdenum wire through non-contact, so the processing will reduce the The perception ability of molybdenum wire, and there is no way to make rapid adjustments according to the tension of molybdenum wire, which reduces the precision of processed products

[0003] In addition, when the wire drum is running clockwise and counterclockwise, due to the uneven tension distribution of the molybdenum wire, the molybdenum wire and the workpiece to be processed will interact to generate discharge repulsion during the discharge process, and the repulsion will cause molybdenum The amount of deformation produced by the wire is related to the repulsion force and the tension of the molybdenum wire. Therefore, whether the design of the wire feeding mechanism is reasonable or not will directly affect the surface roughness of the processed workpiece and affect the cutting accuracy.
