Molybdenum wire guide for electric spark wire cutting machine

Abstract

The invention relates to the guider regulating the movement track of the molybdenum wire. It is a electrical spark wire cutting machine's guider. It features in the hollow cylindrical support base with notch at one side, surrounded by a limit structure with the shape like the Chinese character 'pin' connected by diamond, spring and micro tune bolt sequentially. It can increase the surface machining gross degree from 3.2 mu m to 2.5 mu m.

Description

Technical field [0001] The invention relates to a guide for a molybdenum wire movement track of a wire-cut electric discharge machine tool, and belongs to the technical field of the design of the wire-cut electric discharge machine tool. Background technique [0002] The molybdenum wire of the wire EDM machine has a certain degree of deflection. Because the electrode wire is not fully flexible and has a certain degree of rigidity, there are certain defects in positioning with the guide wheel, that is, the positioning area of ​​the guide wheel is "parabolic", and the molybdenum wire When moving at a high speed of 10.5m / s along the guide wheel, the movement trajectory is irregular, and the molybdenum wire of the cutting workpiece will inevitably shake, which will cause the processing surface to be rough and reduce the accuracy. In the past, a variety of structures were used to improve. Such as: reducing the running speed of the molybdenum wire, increasing the rigidity of the whole ...
