Abstract
The invention discloses a wire guide for a wire cut electrical discharge machine, which comprises a wire guide body, wherein the wire guide body consists of two semicylinders in the same shape and structure; one end of one semicylinder is connected with one end of the other semicylinder by a pin; magnets attracting mutually are arranged at the other ends of the two semicylinders; V-shaped grooves in the same shape and structure are formed on the inner sides of parallel surfaces of the two semicylinders; and an electrode wire penetrates through the two V-shaped grooves and is contacted with walls of the two V-shaped grooves. With the adoption of the mode, the guide is simple in structure, facilitates wire penetration, and ensures that the electrode wire is vertical and stable between an upper guide wheel and a lower guide wheel, thereby improving machining precision.
Description
Technical field
The present invention relates to Wire EDM apparatus field, particularly relate to a kind of WEDM filar guide.
Background technology
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.
In cutting on line process; because wire electrode is driven by wire storage tube; transmission is carried out through guide frame guide wheel etc.; wire electrode jitter phenomenon is often there will be apart from a middle segment electrode silk at upper lower tumbler; the quality of impact processing, causes the fineness of cutting poor, and cutting accuracy is unstable; after cutting, the uniformity of workpiece can not ensure, completely also to problems such as the life-span of guide wheel have an impact.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of WEDM filar guide, and structure is simple, it is convenient to wear silk, ensures that wire electrode is vertical between upper lower tumbler, stable, thus improves machining accuracy.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of WEDM filar guide, comprise: filar guide body, described filar guide body is made up of two shapes, semicylinder that structure is identical, one end of described two semicylinders is connected by pin, the other end is provided with the magnet of attracting each other, a shape, V-type groove that size is all identical is all offered inside the parallel surface of described two semicylinders, wire electrode through described two V-type grooves, and all contacts with the cell wall of described two V-type grooves.
In a preferred embodiment of the present invention, described filar guide body is made up of polycrystalline diamond.
In a preferred embodiment of the present invention, after described two V-type grooves fasten, form square groove.
In a preferred embodiment of the present invention, the cross section of described square groove is in square, and described square is the circumscribed quadrilateral of wire electrode circular cross section.
The invention has the beneficial effects as follows: a kind of WEDM filar guide of the present invention, structure is simple, wear silk convenient, wire electrode contacts with the cell wall of the V-type groove of two on filar guide body, can be within it spacing preferably by wire electrode, ensure that wire electrode is vertical between upper lower tumbler, stable, thus improve machining accuracy.
