Slow wire feeding electric spark processor

Abstract

The invention relates to the technical field of electric spark processing, in particular to a slow wire feeding electric spark processor. The slow wire feeding electric spark processor comprises a fixed shell, a lifting mechanism, a first moving mechanism, a second moving mechanism, a rotating mechanism, an impurity removing mechanism and an electric spark mechanism. A workpiece can be driven by the lifting mechanism, the first moving mechanism and the second moving mechanism to move freely on X-axis, Y-axis and Z-axis directions, and the workpiece is cut conveniently from multiple directionsby means of wire electrode spark discharge, so that the demand on the workpiece is reduced. The workpiece is finally mounted and fixed on a mounting head of the rotating mechanism, and the workpiece can rotate by means of the rotating mechanism to be cut rotatably, so that the cutting efficiency is improved and different demands on the workpiece are met. A filter screen is arranged in a working fluid groove of the fixed shell and at the bottom of a wire electrode, and a third hydraulic cylinder and a lifting plate are arranged at the bottom of the filter screen, so that electric corrosion waste residues generated in a working fluid as a result of cutting are cleaned timely.

Description

technical field [0001] The invention relates to the technical field of electrical discharge machining, in particular to a slow-moving wire electrical discharge machining machine. Background technique [0002] Slow-moving wire is a kind of CNC machining that uses continuously moving thin metal wires (called electrode wires, generally copper wires) as electrodes to perform pulse spark discharge on workpieces, generate high temperatures above 6000 degrees, etch away metals and cut into workpieces machine tool. The principle of slow wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. EDM refers to the method of processing the workpiece through the electric erosion effect of the pulse discharge between the tool electrode and the workpiece electrode in a certain medium. EDM is a method of processing using electricity and heat energy that was studied in the 1940s and gradually applie...

AI Technical Summary

Problems solved by technology

[0003] In the process of slow wire EDM, the movement and cutting of the workpiece is inconvenient, and the direction of the movement and cutting of the workpiece cannot be adjusted, so the requirements for cutting the workpiece are relatively high

Then, because spark discharge cutting is caused by electric corrosion, electric corrosion residue will be generated in the working fluid during cutting. If it is not treated in time, it will affect the use of the working fluid.
