Abstract

The invention discloses a contact wire electrode stop comprising a base, a wire electrode and a stop bar. The base is in the rectangular structure. A recessed V-shaped groove is formed in the middle of a long side of the rectangular base. The wire electrode penetrates the V-shaped groove to be contacted with the bottom of the same. The stop bar is in the long and thin cylinder structure and arranged at an opening of the V-shaped groove. One side wall of the stop bar contacts with the wire electrode and limits the same in the V-shaped groove. According to the arrangement, the contact wire electrode stop is simple in structure and convenient to penetrate the wire, the wire electrode is effectively limited, thereby being protected from shaking in operating, and accordingly production accuracy is improved and quality of the surfaces of the workpieces is increased.

Description

A kind of contact electrode silk stop

Technical field

The present invention relates to Wire EDM apparatus field, particularly relate to a kind of contact electrode silk stop.

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 HS WEDM, wire electrode is subject to Discharge Force, rushes the effect of some power such as fluid power, tension force, when these power can not balance, wire electrode can change in the position of processing district, workpiece causes geometric error, thus reduction machining accuracy, have a strong impact on surface of the work crudy.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of contact electrode silk stop, and structure is simple, wears silk convenient, effectively can limit the position of wire electrode, prevent the shake in its work process, thus improves machining accuracy, raising surface of the work crudy.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of contact electrode silk stop, comprise: pedestal, wire electrode and limit stick, described pedestal is rectangular structure, a V-type groove be inwardly recessed is offered in the centre of described cuboid pedestal one long side, described wire electrode is through described V-type groove, and contact with the bottom land of described V-type groove, described limit stick is elongate cylinder body structure, described limit stick is positioned at the notch place of described V-type groove, one sidewall of described limit stick contacts with described wire electrode, and described wire electrode is limited in described V-type groove.

In a preferred embodiment of the present invention, the sidewall of described limit stick length direction offers an arc groove be inwardly recessed.

In a preferred embodiment of the present invention, described arc groove and described V-type groove are parallel to each other, and described wire electrode is between described arc groove and described V-type groove.

In a preferred embodiment of the present invention, described pedestal is the pedestal be made up of polycrystalline diamond.

In a preferred embodiment of the present invention, described limit stick is the limit stick be made up of Hardmetal materials.

The invention has the beneficial effects as follows: a kind of contact electrode silk of the present invention stop, comprise: pedestal, wire electrode and limit stick, structure is simple, wear silk convenient, effectively can limit the position of wire electrode, prevent the shake in its work process, thus improve machining accuracy, raising surface of the work crudy.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of contact electrode silk of the present invention stop one preferred embodiment;

In accompanying drawing, the mark of each parts is as follows: 1, pedestal, and 2, limit stick, 3, wire electrode, 11, V-type groove, 21, arc groove.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

Refer to Fig. 1, the embodiment of the present invention comprises:

A kind of contact electrode silk stop, comprise: pedestal 1, wire electrode 3 and limit stick 2, described pedestal 1 is in rectangular structure, be made up of polycrystalline diamond, have wear-resisting, the feature of long service life, a V-type groove 11 be inwardly recessed is offered in the centre of described cuboid pedestal 1 one long side, described wire electrode is through described V-type groove 11, and contact with the bottom land of described V-type groove 11, described limit stick 2 is in elongate cylinder body structure, be made up of Hardmetal materials, there is location reliable, the feature of low cost of manufacture, described limit stick 2 is positioned at the notch place of described V-type groove 11, one sidewall of described limit stick 2 contacts with described wire electrode 3, and described wire electrode 3 is limited in described V-type groove 11.

Preferably, the sidewall of described limit stick 2 length direction offers an arc groove be inwardly recessed 21, described arc groove 21 is parallel to each other with described V-type groove 11, and described wire electrode 3 is between described arc groove 21 and described V-type groove 11.Due to wire electrode 3 high-speed friction on limit stick 2, and the hardness of wire electrode 3 is larger, therefore be easy to grind one groove on limit stick 2 surface, limit effect is deteriorated, described limit stick 2 is offered an arc groove 21, wear silk convenient, and this arc groove 21 can limit to wire electrode 3 is multi-faceted, limit effect is better.

Present invention is disclosed a kind of contact electrode silk stop, comprise: pedestal, wire electrode and limit stick, structure is simple, wear silk convenient, can the position of comprehensive restriction wire electrode by the arc groove on limit stick and the V-type groove on pedestal, prevent the shake in its work process, thus improve machining accuracy, raising surface of the work crudy.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
