Description

A kind of high accuracy wire feeder

Technical field

The utility model relates to Wire EDM apparatus field, particularly relates to a kind of high accuracy wire feeder.

Background technology

WEDM (Wire cut Electrical Discharge Machining is called for short WEDM), belong to electric machining category, when studying switch contact by the phenomenon of spark discharge corrosion and damage and reason by former Soviet Union La Zhalinke Mr. and Mrs, find that the TRANSIENT HIGH TEMPERATURE of electric spark can make the metal molten of local, oxidation and being corroded, thus started and invented electric discharge machining method.Operation principle is that free cation and electronics accumulate in field, forms a conductive channel be ionized very soon.In this stage, between two plates, form electric current.Cause occurring between particle to collide many times, form an ion plasma, and be elevated to the high temperature of 8000 to 12000 degree very soon, at two some materials of conductive surface instant melting, meanwhile, due to the vaporization of electrode and electrolyte, form a bubble, and its pressure rule rises until very high.Then current interruptions, temperature reduces suddenly, causes bubble implosion, and the power of generation is dished out the material dissolved crater, and the material be then corroded regelation in electrolyte becomes little spheroid, and is drained by electrolyte.Then the monitoring controlled by NC and management and control, servo control mechanism performs, and make this electric discharge phenomena uniformity, thus it is processed to reach machining object, makes it the product becoming size and the form accuracy meeted the requirements.

China produces and the overwhelming majority of use is High-speed Wire Electro-Discharge Machine, High-speed Wire Electro-Discharge Machine is as the original creation technology of China, become one of machine that in China NC Machine, output is maximum, most widely used, along with the develop rapidly of China's die industry, WEDM is had higher requirement, thus also further promotes the development of Electric Discharge Wire-cutting Technology.

High speed travelling wire can cause the wearing and tearing of guide wheel and the vibration of system, and add that the tension force of wire electrode is not easy to control, it will bring to processing stability, machining accuracy and surface quality and have a strong impact on.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of high accuracy wire feeder, can tensioning wire electrode, avoids system vibration to produce wire electrode jitter phenomenon, wire is stablized, effectively improves machining accuracy.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of high accuracy wire feeder, comprise: wire storage tube, capstan, auxiliary guide wheel, wire reeling rack, inserting rack and strainer, described strainer is positioned at described wire storage tube and described wire reeling rack, between inserting rack, described capstan has four, wherein two are fixed on the two ends up and down of described strainer, another two are fixed on described wire reeling rack, the two ends of inserting rack, described auxiliary guide wheel has two, be positioned at described strainer and described wire reeling rack, between inserting rack, wire electrode is through capstan, auxiliary guide wheel is back and forth alternately mobile by the action of wire storage tube band.

In the utility model preferred embodiment, described wire reeling rack is identical with inserting rack structure, all in cuboid column, and it is parallel to each other.

In the utility model preferred embodiment, described four capstans are positioned in same level.

In the utility model preferred embodiment, outside the side of described two auxiliary guide wheels, the outer tangent line of tangent line and described wire storage tube is a horizontal linear.

The beneficial effects of the utility model are: a kind of high accuracy wire feeder of the utility model, be made up of wire storage tube, capstan, auxiliary guide wheel, wire reeling rack, inserting rack and strainer, can tensioning wire electrode, system vibration is avoided to produce wire electrode jitter phenomenon, wire is stablized, thus effectively improves machining accuracy.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of high accuracy wire feeder one of the utility model preferred embodiment;

In accompanying drawing, the mark of each parts is as follows: 1, wire storage tube, and 2, capstan, 3, auxiliary guide wheel, 4, wire reeling rack, 5, inserting rack, 6, strainer.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of high accuracy wire feeder, comprising: wire storage tube 1, capstan 2, auxiliary guide wheel 3, wire reeling rack 4, inserting rack 5 and strainer 6; Described strainer 6 between described wire storage tube 1 and described wire reeling rack 3, inserting rack 4, for tensioning wire electrode; Described capstan 2 has four, wherein two are fixed on the two ends up and down of described strainer 6, another two two ends being fixed on described wire reeling rack 4, inserting rack 5, and described auxiliary guide wheel 3 has two, between described strainer 6 and described wire reeling rack 4, inserting rack 5, for support electrode silk; Wire electrode is with action back and forth alternately mobile through capstan 2, auxiliary guide wheel 3 by wire storage tube 1.

Wherein, described wire reeling rack 4 is identical with inserting rack 5 structure, all in cuboid column, and it is parallel to each other.For support electrode silk, make wire electrode can stablize movement in the course of the work.

Described four capstans 2 are positioned in same level, and four capstans 2 are symmetrically set, can ensure wire electrode forward and reverse mobile time produce frictional resistance close, make the tension force of wire electrode constant in whole process.

Outside the side of described two auxiliary guide wheels 3, the outer tangent line of tangent line and described wire storage tube 1 is a horizontal linear, described capstan 2, teach wheel 3 together with strainer 6 for tensioning wire electrode, avoid system vibration to produce wire electrode jitter phenomenon, wire is stablized, thus improves cutting accuracy.
