Reciprocating wire-electric discharge machining tool

Abstract

The invention discloses a reciprocating wire-electric discharge machining tool. The reciprocating wire-electric discharge machining tool comprises a working solution box, a body, a lower slide plate, an upper slide plate, a support frame, an overturning table, a rotating table, a working table, a wire conveying device, a power supply and a control cabinet, wherein the working solution box is connected with the body through a solution inlet tube and a solution outlet tube; the lower slide plate is arranged at the upper end of the body; the upper slide plate is arranged at the upper end of the lower slide plate; the overturning table, the rotating table and the working table are successively arranged at the upper end of the upper slide plate; the wire conveying device comprises a wire slide carriage, a protecting cover, a wire storage barrel, a guide wheel, a wire electrode and a wire rack; the overturning table drives the working table to swing; and the rotating table drives the working table to rotate. Requirements of processing of a workpiece at different angles and in different directions are met, and when a stamp die with a blanking oblique angle and certain tapered inner and outer surfaces, particularly large-thickness workpieces, are cut, the circumstance of insufficient supply of working solution due to inclining of the wire electrode is avoided. The reciprocating wire-electric discharge machining tool is simple in structure and reasonable in design; labor intensity of workers can be reduced; and machining precision and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a reciprocating wire electric discharge machine tool. Background technique [0002] Since its birth, WEDM has developed rapidly and has gradually become a high-precision and highly automated processing method. It has been widely used in mold manufacturing, forming tool processing, difficult-to-machine materials and precision and complex parts processing. . In order to cut dies with blanking angles and certain tapered (inclined) inner and outer surfaces, some wire cutting machines have a tapered cutting function. There are mainly two methods: offset wire frame and double coordinate linkage device. These two methods realize the oblique cutting of the workpiece by adjusting the inclination of the electrode wire, but the inclination angle of the electrode wire has certain restrictions, and the inclination of the electrode wire leads to insufficient supply of working fluid, es...

Problems solved by technology

These two methods realize the oblique cutting of the workpiece by adjusting the inclination of the electrode wire, but the inclination angle of the electrode wire has certain restrictions, and the inclination of the electrode wire leads to insufficient supply of working fluid, especially for cutting large thickness. workpiece

If the operator manually adjusts the inclination angle and orientation of the workpiece, it will not only consume time and effort, but also reduce the machining accuracy due to multiple clamping
