A reciprocating wire cut electrical discharge machining tool

Abstract

The invention discloses a reciprocating wire cut electrical discharge machining tool. The tool comprises a wire storage mechanism (400) and a wire conveying mechanism (500), the wire conveying mechanism (500) comprises a first main guide wheel (505), a second main guide wheel (506) and a first guide wheel (525), in a space rectangular coordinate system taking X, Y, and Z axes as the coordinate axes; a wire electrode (600) can sequentially bypass the first guide wheel (525), the first main guide wheel (505) and the second main guide wheel (506) from the wire storage barrel (402), and the wireelectrode (600) located between the first main guide wheel (505) and the second main guide wheel (506) inclines relative to the horizontal plane or is parallel to the horizontal plane. According to the reciprocating wire cut electrical discharge machining tool, transverse cutting of the high-speed wire cut electrical discharge machining tool can be achieved, and therefore the situation that beforecutting is finished, a workpiece is broken along a kerf, and an electrode wire is pinched off can be avoided.

Description

technical field [0001] The invention relates to a reciprocating wire electric discharge wire cutting machine tool. Background technique [0002] At present, the application of wire electric discharge machine tools in manufacturing industry is becoming more and more extensive. As an important branch of electric discharge machine tool, fast wire cutting machine tool has the advantages of high processing efficiency and low processing cost. figure 1 Shown is a reciprocating wire feeding mechanism that is currently widely used in fast wire cutting machine tools. In this mechanism, the electrode wire wound on the wire storage barrel 10 passes through the guide wheel 43, the guide wheel 45, the capstan wheel 41, the capstan wheel 21, and then the guide wheel 25, the guide wheel 23, and finally returns to the wire storage barrel. A cycle loop in which the electrode wire reciprocates is formed. A tension mechanism that applies tension to the electrode wire is set in the circuit. ...
