Wire-electrode cutting machine

Abstract

The wire electrode cutting machine includes upright column, upper wire holder, lower wire holder, wire storing disc, guide wheels on the upper wire holder and the lower wire holder separately, molybdenum wire tensed between the wire storing disc and the guide wheels, one height adjusting mechanism between the upper wire holder and the upright column and one other height adjusting mechanism between the lower wire holder and the upright column. Owing to the two height adjusting mechanisms, both the upper wire holder and the lower wire holder may be adjusted properly, so that the upper wire holder and the lower wire holder may be inserted into mold cavities, even of different shapes in height direction and different vertical cutting paths, to cutting.

Description

technical field [0001] The invention relates to a wire electric discharge machine tool. Background technique [0002] In the prior art, the wire cutting machine tool includes a column, an upper wire rack, a lower wire rack, a wire storage tray, guide wheels respectively arranged on the upper wire rack and the lower wire rack, and tensioned on the wire storage tray and the guide wheel. Molybdenum wire between the wheels, a height adjustment mechanism is provided between the upper wire frame and the column, and the height adjustment mechanism enables the upper wire frame to be adjusted and positioned in the height direction relative to the column. And the lower wire frame is fixed on the column, and the height of the lower wire frame cannot be adjusted. When cutting the workpiece, since the worktable with the workpiece cannot move up and down, the front ends of the upper and lower wire racks cannot extend into the cavity of the workpiece with different heights, especially the...

AI Technical Summary

Problems solved by technology

The lower wire rack is fixed on the column, and the height of the lower wire rack cannot be adjusted.

When cutting the workpiece, since the worktable with the workpiece cannot move up and down, the front ends of the upper and lower wire racks cannot extend into the cavity of the workpiece with different heights, especially the cavity of some workpieces. When there are more than one in the vertical direction (such as a shoe mold), the wire cutting machine with a fixed lower wire frame cannot perform processing operations that extend into the cavity
