Detailed Description of the Embodiment

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0030] This application discloses a wire threading wire guide tube for wire cutting, as Figure 5 The wire guide tube is installed on the driving member, the driving member is installed on the lower head of the wire cutting machine tool, and is arranged on one side of the wire winding cylinder. A reinforcing member made of wear-resistant material is installed at one end of the wire guide tube close to the wire winding cylinder, solving the problem that the inner hole at one end of the wire guide tube close to the wire winding cylinder in the prior art is prone to wear.

[0031] As Figure 1 shown, the wire threading wire guide tube 1 for wire cutting includes: a wire guide tube 1 and a reinforcing member.

[0032] The guide wire tube 1 is provided with a guide wire hole, and the reinforcing member is arranged at one end of the guide wire hole close to the wire winding cylinder 4.

[0033] One end of the reinforcing member away from the wire winding cylinder 4 is provided with a guiding structure. One end of the reinforcing member close to the wire winding cylinder 4 is flush with the end of the guide wire tube 1 or extends a predetermined distance through the guide wire tube 1 towards the wire winding cylinder 4. For example, Figure 1 as shown, one end of the reinforcing member close to the wire winding cylinder 4 is flush with the end of the guide wire tube 1.

[0034] The reinforcing member is made of wear-resistant material.

[0035] Regarding the reinforcing member, the reinforcing member is made of ceramic material, diamond or cemented carbide material.

[0036] The reinforcing member can be a sheet body arranged on the inner wall of the guide wire tube 1, or the reinforcing member includes: the reinforcing member 201 arranged in the guide wire hole. One end of the reinforcing member 201 close to the wire winding cylinder 4 is flush with the end of the guide wire tube 1 or extends a predetermined distance through the guide wire tube 1 towards the wire winding cylinder 4. For example, Figure 1 as shown, one end of the reinforcing member 201 close to the wire winding cylinder 4 is a sharp-cornered structure flush with the end of the guide wire tube 1.

[0037] In Figure 2 the shown embodiment, the reinforcing member further includes: an upper guiding member 202 and a lower guiding member 203. A first guiding portion 2022 is provided at the bottom end of the upper guiding member 202, and a second guiding portion 2032 is provided at the top end of the lower guiding member 203. The first guiding portion 2022 and the second guiding portion 2032 cooperate to form a guiding structure, wherein the first guiding portion 2022 and the second guiding portion 2032 are mutually cooperating arc surface structures or inclined surface structures. For example, Figure 3 as shown, the first guiding portion 2022 and the second guiding portion 2032 are two semi-truncated cone-shaped arc surface structures, or the first guiding portion 2022 and the second guiding portion 2032 can be two semi-prism-shaped inclined surface structures.

[0038] The length of the upper half of the reinforcing member 201 is less than the length of the lower half. The upper guiding member 202 is connected to the upper half of the reinforcing member 201, and the lower guiding member 203 is connected to the lower half of the reinforcing member 201.

[0039] During the wire threading operation, the electrode wire sequentially passes through the lower guiding member 203, the lower half of the reinforcing member 201, the upper guiding member 202, and one end of the reinforcing member 201 close to the wire winding cylinder 4 and extends towards the wire winding cylinder 4.

[0040] It can guide the electrode wire to extend upward first and then downward. Multiple guidances on the electrode wire can improve the passing rate of the electrode wire. Especially when the electrode wire is molybdenum wire, the passing rate of the electrode wire is greatly improved. During wire cutting work, it can provide multi-point support for the electrode wire and reduce the contact area between the electrode wire and the reinforcement 201.

[0041] In this embodiment, as Figure 3 shown, a first groove portion 2021 is provided at the bottom end of the upper guide member 202.

[0042] A second groove portion 2031 is provided at the top end of the lower guide member 203.

[0043] As Figure 4 shown, the first groove portion 2021 and the second groove portion 2031 are semi-hole-shaped structures.

[0044] The radial dimension of the hole surrounded by the first groove portion 2021 and the second groove portion 2031 is smaller than the diameter of the reinforcement 201.

[0045] The first groove portion 2021 and the second groove portion 2031 can be provided between the first guide portion 2022 and the second guide portion 2032 and the reinforcement 201, or the first groove portion 2021 and the second groove portion 2031 can be not provided, so that the first guide portion 2022 and the second guide portion 2032 directly extend to the position where they are connected to the reinforcement 201.

[0046] Regarding the wire guide tube 1, as Figure 1 shown, one end of the wire guide tube 1 and the reinforcement close to the wire winding cylinder 4 is a "V"-shaped structure 101 or a "U"-shaped structure.

[0047] In this embodiment, platform structures 102 are provided above and below the side wall of the wire guide tube 1, and the platform structures 102 are connected to the "V"-shaped structure 101 or the "U"-shaped structure.

[0048] The wire guide tube 1 can cooperate with the wire clamping device. The "V"-shaped structure 101 or the "U"-shaped structure can open the wire clamping device, and the platform structures 102 can improve the stability of the cooperation between the wire guide tube 1 and the wire clamping device.

[0049] Working method: First, the wire feeding device of the wire cutting machine tool transports the electrode wire into the wire guide tube 1.

[0050] Then the driving member 3 drives the wire guide tube 1 to insert into the wire clamping device installed on the wire winding cylinder 4. During this process, the electrode wire extends a sufficient distance in the wire guide tube 1 so that the end of the electrode wire always remains in the wire guide tube 1.

[0051] Then the wire feeding device continues to transport the electrode wire so that the electrode wire in the wire guide tube 1 extends into the wire clamping device.

[0052] Finally, the driving member 3 drives the wire guide tube 1 to withdraw from the wire clamping device, so that the wire clamping device clamps the electrode wire.

[0053] 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 in form and detail may be made thereto without departing from the spirit and scope of the present invention as defined by the appended claims.
