[0025] In the following description, numerous specific details are given to provide a more thorough understanding of the present utility model. However, it will be apparent to one of ordinary skill in the art that the present utility model may be practiced without one or more of these details. In other instances, well-known features have not been described to avoid obscuring the present utility model.
[0026] The present application discloses a wire cutting guide wire eye mold core, which is installed on the upper and lower machine heads of a wire cutting machine tool. By arranging the guiding member made of wear-resistant material between the housing and the stopper, the volume of the wear-resistant material is reduced, and the processing cost of the wear-resistant material is reduced, solving the problem of high cost of the eye mold core in the prior art.
[0027] As Figure 1The wire-cutting guide wire eye die core shown includes: a housing 1 with a cylindrical structure, a guiding member 2, and a stopping member 3, and its shape can be adjusted according to actual needs.
[0028] The housing 1 is connected to the stopping member 3, and the guiding member 2 is arranged between the housing 1 and the stopping member 3.
[0029] The housing 1 is provided with a first hole 11, the guiding member 2 is provided with a second hole 21, and the stopping member 3 is provided with a third hole 31. The aperture of the second hole 21 is smaller than the apertures of the first hole 11 and the third hole 31.
[0030] The guiding member 2 is made of wear-resistant material. Among them, the guiding member 2 is made of diamond material, the housing 1 is made of stainless steel, copper, aluminum or ceramic material, and the stopping member 3 is made of stainless steel, copper or aluminum material.
[0031] In this embodiment, the housing 1 and the stopping member 3 are of an integral structure.
[0032] Or the housing 1 and the stopping member 3 are in interference fit. As Figure 1 shown, the stopping member 3 is press-fitted into the housing 1 to make the housing 1 and the stopping member 3 in interference fit.
[0033] Regarding the guiding member 2, as Figure 1 and 2 shown, a second guiding portion 22 is provided at the top end of the second hole 21. The top end size of the second guiding portion 22 is larger than the aperture of the first hole 11. Among them, the second guiding portion 22 is a frustum-shaped structure or a prism-shaped structure. As Figure 1 shown, the second guiding portion 22 is a frustum-shaped hole.
[0034] By setting the top end size of the second guiding portion 22, the electrode wire coming out of the first hole 11 can be guided into the second hole 21.
[0035] In this embodiment, a chamfer structure is provided between the second hole 21 and the second guiding portion 22. The chamfer structure can be a rounded chamfer or an inclined chamfer. As Figure 1 and 2 shown, the chamfer structure is a rounded chamfer.
[0036] In this embodiment, a chamfer structure is provided between the second hole 21 and the bottom wall of the guiding member 2. The chamfer structure can be a rounded chamfer or an inclined chamfer. As Figure 1 and 2 shown, the chamfer structure is a rounded chamfer.
[0037] Regarding the housing 1, a first guiding portion 12 is provided at the top end of the first hole 11. Among them, the first guiding portion 12 is a frustum-shaped structure or a prism-shaped structure. As Figure 1 shown, the first guiding portion 12 is a frustum-shaped hole.
[0038] As Figure 1At least one groove portion 13 is provided at the top end of the shown housing 1. One end of the groove portion 13 extends to the first hole 11, and the other end extends to the outer wall of the housing 1.
[0039] Working method: The wire-cutting guide wire eye die core is arranged in the upper and lower machine heads of the wire-cutting machine tool. In the wire threading process, the electrode wire sequentially passes through the first hole 11, the second hole 21, and the third hole 31.
[0040] During the wire-cutting process, when the electrode wire is deflected, since the aperture of the second hole 21 is smaller than the apertures of the first hole 11 and the third hole 31, the electrode wire only contacts the guide member 2. And because the guide member 2 is made of wear-resistant material, it can ensure the normal operation of the eye die core while reducing the volume of the wear-resistant material and the processing cost of the eye die core.
[0041] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
