Wire guiding device for electric spark linear cutting machine tool

Abstract

The invention discloses a wire guiding device for an electric spark linear cutting machine tool. The wire guiding device comprises a fixed base, a left sliding block, a right sliding block, a middle sliding block, an upper right fixed sliding block, an upper left fixed sliding block and sliding block fixing nuts. The fixed base is provided with a left sliding groove, a right sliding groove, a middle sliding groove, an upper right hole and an upper left hole. The left sliding block is in sliding connection with the left sliding groove and fixed to the appropriate position of the left sliding groove through the corresponding sliding block fixing nut, the right sliding block is in sliding connection with the right sliding groove and fixed to the appropriate position of the right sliding groove through the corresponding sliding block fixing nut, and the middle sliding block is in sliding connection with the middle sliding groove and fixed to the appropriate position of the middle sliding groove through the corresponding sliding block fixing nut. The upper right fixed sliding block and the upper left fixed sliding block are in clearance fit with the upper right hole and the upper left hole correspondingly, and fixed to the fixed base through the corresponding sliding block fixing nuts. The wire guiding device can be adjusted in different directions to tension an electrode wire, andis simple in structure, low in cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of a wire electric discharge machine tool, in particular to a wire guide device of a wire electric discharge machine tool. Background technique [0002] Wire-cut electric discharge machining technology is a processing method developed in the 1950s. It has been widely used in mold manufacturing, row tool processing, difficult-to-machine materials and precision and complex parts processing. The wire-cutting machine tool uses the electric erosion effect generated by the electric spark pulse discharge in the working fluid between the electrode wire and the workpiece to carry out wire-cutting processing. Due to the limited length of the electrode wire, reciprocating wire cutting is used for cutting, which requires frequent normalization of the wire drum. , Reciprocate and alternate directions in the opposite direction. In order to obtain higher processing efficiency and processing quality, the electrode wire need...

AI Technical Summary

Problems solved by technology

When the workpiece is processed by the wire cutting machine tool, because the electrode wire is generally molybdenum wire, which has ductility, it will be stretched and loosen after working for a period of time, and the electrode wire will vibrate greatly, resulting in a significantly larger surface roughness and quality defects.
