Abstract
The wire electrode moving method is that the rotating wire electrode storing drum drives the wire electrode to move linearly via the idler pulley so as to cut workpiece by means of electrospark. The present invention features that the wire electrode is welded into an integral with connected ends. When the wire electrode storing drum rotates in some direction, one wire arranger winds the wire electrode onto the drum tidily while making the wire electrode shift axially to the outlet end so that the wire electrode can shift in one way circularly.
Description
The present invention relates to a kind of wire-walking method of electric spark linear cutting machine.
In the prior art, electric spark linear cutting machine is divided into be careful silk and fast wire two classes, what present Chinese domestic manufacturer produced mainly is quick-wire-moving linear cutting machine, the wire-moving system of fast wire lathe mainly is to be used for driving wire electrode to move by certain linear velocity, and wire electrode fitly arranged on wire storage tube, concrete grammar is that the rotation by wire storage tube drives wire electrode on the wire storage tube and moves as straight line by guide wheel workpiece is carried out the spark discharge cutting processing.When wire storage tube rotates, also to move axially accordingly, to guarantee wire electrode dead cast on wire storage tube, during near the wire electrode end (the wire electrode two ends are screwed on wire storage tube), the wire storage tube backward rotation oppositely moves axially simultaneously, and it is mobile that wire electrode is commutated repeatedly.Because the at a high speed wire storage tube reciprocating reversing of rotation motion produces impact shock when commutation, make the process instability, thereby influence the surface quality and the precision of work piece, because can not cutting processing in the dead time of commutating, influence cutting rate.
Come and go the problem that is produced that moves for solving wire electrode, common way is the linear velocity of wire electrode of slowing down, increase wire electrode length, the disposable one-way that makes wire electrode do to circulate when work moves, this is the main method that the thread feed electric spark wire-electrode cutting machine wire-moving system adopts of being careful now, this is difficult to adopt on quick-wire-moving linear cutting machine, Chinese patent 95211384.8 proposes a wire drive device that unidirectional rotation of wire electrode high speed and unidirectional at a slow speed straight line are moved, though this device can be applied to quick-wire-moving linear cutting machine, wire electrode still can only be done to circulate unidirectionally moves at a slow speed.
The objective of the invention is to provide a kind of wire-walking method of the electric spark linear cutting machine that need not commutate, it can make unidirectional circularly the moving of wire electrode carry out Wire-cut Electrical Discharge Machining.
The object of the present invention is achieved like this, wire electrode makes it be welded into integral body from beginning to end by welder, when the wire storage tube one-directional rotation, use thread arranging device to make wire electrode (going into end) fitly on wire storage tube, and making the wire electrode on the wire storage tube constantly move axially to out end at wire storage tube upper edge wire storage tube, wire electrode is unidirectional circularly to be moved thereby make.
Because wire electrode head and the tail of the present invention are welded into an integral body by welder, wire storage tube does not commutate, does not move, one-directional rotation only, so no matter wire storage tube is with which kind of speed rotation, can realize that all wire electrode is unidirectional mobile, vibration, cutting technique instability, the work piece cut face that can avoid the wire storage tube commutation to be brought like this has problems such as cutting striped.And the length wire electrode all can use, and lathe operating cost is reduced.The present invention has saved commutation idle hours owing to do not commutate in the cutting process, and lathe production efficiency is improved greatly.
The following describes implementation detail of the present invention.Wire electrode welder, thread arranging device that the present invention proposes are installed on the lathe as the parts of lathe.Because wire electrode welding back joint is rough, need tentatively use the smoothing of opposite wire drawing die again after the finishing to welding point with an opposite cutting tool, makes the diameter of joint identical with the diameter dimension of wire electrode integral body.When the wire storage tube one-directional rotation, use thread arranging device to make wire electrode (going into end) fitly on wire storage tube, and make the wire electrode on the wire storage tube constantly move axially to out end at wire storage tube upper edge wire storage tube, when on the wire storage tube around wire electrode when too many, wire electrode moves axially at wire storage tube upper edge wire storage tube may be not smooth, for this reason the diameter of wire storage tube go out end can be slightly little, i.e. each section of wire storage tube diameter difference.
Claims (3)
1, the wire-walking method of electric spark linear cutting machine.This method is to move as straight line by guide wheel by the wire electrode on the rotation drive wire storage tube of wire storage tube workpiece is carried out the spark discharge cutting processing, it is characterized in that wire electrode makes it be welded into integral body from beginning to end by welder, when the wire storage tube one-directional rotation, use thread arranging device to make wire electrode (going into end) fitly on wire storage tube, and making the wire electrode on the wire storage tube constantly move axially to out end at wire storage tube upper edge wire storage tube, wire electrode is unidirectional circularly to be moved thereby make.
