Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a square cutting machine and a wire passing wheel thereof. Background Art

[0002] In the monocrystalline silicon industry, traditional single crystal round bars are processed into square bars through truncation, squaring, and grinding. During the squaring process, diamond wire cutting needs to form a wire mesh to cut the round bar. During the wiring mesh process, the diamond wire needs to pass through the wire wheel. The wire wheel mainly plays a process support role between the cutting wheels. At the same time, the wire wheel cooperates to change the threading direction of the diamond wire and finally forms a wire mesh. During the production process, the wire wheel will rotate at high speed driven by the diamond wire, wear quickly, and need to be replaced frequently.

[0003] like Figures 1 to 9 As shown, the conventional wire-passing wheel comprises a wheel frame 01 and a cover 02 detachably connected to the wheel frame 01, wherein the cover 02 is a rubber ring. The wheel frame 01 is an aluminum disc structure diagram. Since the rubber ring is made of polyurethane material, the service life is short, resulting in the rubber ring needing to be replaced frequently manually, which shortens the service life of the wire-passing wheel.

[0004] Therefore, how to extend the service life of the wire wheel is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0038] Please refer to Figure 10-12 .

[0039] In a specific embodiment, the wire passing wheel of the square cutting machine provided by the specific embodiment of the utility model comprises a wheel frame 1 and an outer sleeve 2, the outer sleeve 2 is located at the periphery of the wheel frame 1 and is arranged in an annular shape, the wheel frame 1 is fixedly connected to the outer sleeve 2, and the outer sleeve 2 is provided with a groove body for winding the wire around the outer periphery, and the surface of the groove body is a wear-resistant layer, and specifically, the wear-resistant layer can be processed from a polymer polyethylene material. The wire passing wheel provided in this application can be used in a single crystal square rod square cutting machine.

[0040] The wheel body frame 1 is provided with a mounting hole 14, which is a straight bar-shaped through-hole structure. During installation, there is no need to distinguish the installation position of the wire wheel, thereby improving installation convenience.

[0041] In order to facilitate the installation of the protective cover, the wheel body frame 1 is provided with a protective cover installation hole 15 for installing the protective cover.

[0042] When using the wire wheel, install the wire wheel in place and wind the wire around the groove.

[0043] From the above description, it can be seen that in the wire passing wheel provided in the specific embodiment of the present application, since the surface of the groove body is provided with a wear-resistant layer, when the wire rubs against the groove body, the wear of the groove body position is reduced, thereby extending the service life of the wire passing wheel.

[0044] In order to improve assembly efficiency, preferably, the material of the outer jacket 2 is a wear-resistant material. Specifically, the outer jacket 2 can be made of a traditional composite polymer material. The material of the outer jacket 2 is a wear-resistant material as a whole, and there is no need to set a wear-resistant layer separately. In a specific embodiment, the material of the outer jacket 2 is a polymer polyethylene material.

[0045] Specifically, the wheel frame 1 is a nylon frame, that is, the wheel frame 1 is made of nylon material.

[0046] Specifically, during assembly, the outer sleeve 2 is bonded to the outer periphery of the wheel frame 1 .

[0047] The wire-passing wheel provided in the present application uses a high-molecular polyethylene with good wear resistance as the outer shell 2, and the wheel body frame 1 uses nylon material, which can extend the service life, reduce the cost of using auxiliary materials, and also reduce the labor cost of frequently replacing the wire-passing wheel.

[0048] like Fig.10As shown, in a specific embodiment, a center hole is set in the middle of the wheel frame 1, and the wheel frame 1 includes a mounting portion 13, a weight-reducing portion 11, and a jacket connection portion 16 which are sequentially arranged from the center hole outward, and the thickness of the mounting portion 13 and the thickness of the jacket connection portion 16 are both greater than the thickness of the weight-reducing portion 11, wherein the thickness direction is the axial direction of the center hole, and the mounting portion 13 is provided with a mounting hole 14 for mounting the wire wheel. The mounting portion 13, the weight-reducing portion 11, and the jacket connection portion 16 are all in an annular structure which is sequentially sleeved.

[0049] The protective cover mounting hole 15 is arranged on the mounting portion 13. A plurality of protective cover mounting holes 15 are provided, and the plurality of protective cover mounting holes 15 are arranged circumferentially with the center of the central hole as the center of the circle.

[0050] In order to reduce the weight of the wheel frame 1, preferably, the weight-reducing portion 11 is provided with weight-reducing holes 12 arranged circumferentially with the central hole as the center. Specifically, the weight-reducing holes 12 are preferably waist-shaped holes with smooth transitions at the corner positions to reduce stress concentration and extend the service life of the wire wheel.

[0051] Specifically, the thickness of the mounting portion 13 is greater than the thickness of the outer sleeve connecting portion 16. Since the outer sleeve connecting portion 16 does not involve a connecting piece, the thickness of the outer sleeve connecting portion 16 is thinned, which further reduces the weight of the wheel frame 1, saves materials, and reduces manufacturing costs.

[0052] In a specific embodiment, the mounting hole 14 is a stepped hole. There are multiple mounting holes 14. Specifically, the number of mounting holes 14 is the same as the number of protective cover mounting holes 15. A protective cover mounting hole 15 is provided between two adjacent stepped holes.

[0053] A plurality of mounting holes 14 are arranged circumferentially with the center of the central hole as the center of the circle.

[0054] like Fig.11 As shown, specifically, the stepped hole includes a through hole 143 and a locking hole 142, the through hole 143 connects two opposite sides of the mounting portion 13 in the thickness direction, and the locking hole 142 and the through hole 143 are connected at the edge with a step surface 141 supporting the fastener, when the fastener is located in the through hole 143, the fastener can pass through the through hole 143 and be detachably arranged with the wire wheel, when the fastener is located in the locking hole 142, the fastener is installed in a position to abut against the step surface 141 to lock the wire wheel. With such a configuration, when the wire wheel needs to be disassembled, it is not necessary to disassemble all the fasteners before disassembling the wire wheel, thereby improving the efficiency of disassembling and assembling the wire wheel.

[0055] Specifically, the fastener may be a threaded fastener, and the through hole 143 is a circular hole having a size larger than the nut of the threaded fastener. The locking hole 142 is a bar-shaped hole having a size larger than the screw of the threaded fastener and smaller than the nut of the threaded fastener.

[0056] The present application provides a square cutting machine, including a wire passing wheel, wherein the wire passing wheel is any of the above-mentioned wire passing wheels. The above-mentioned specific structure of the wire passing wheel is described, and the present application includes the above-mentioned wire passing wheel, and also has the above-mentioned technical effects.
