[0003] The existing multi-wire cutting machine has a simple cylindrical drum structure, which is connected to the shaft through a bearing structure at the end. There is a certain space between the shaft and the drum. During high-speed rotation, the drum will vibrate relative to the shaft, affecting the accuracy. Summary of the Invention
[0004] This invention provides a single-crystal multi-wire cutting machine roller, which has the advantages of high strength, even distribution of torque, and cylindrical arc design to reduce the occurrence of torque-guided resonance in forward and reverse rotation. This solves the problem that the existing multi-wire cutting machine rollers have a simple cylindrical structure, and the roller vibrates relative to the rotating shaft during high-speed rotation, affecting accuracy.
[0005] To achieve high strength and evenly distribute torque, the cylindrical arc design can mitigate the occurrence of torque-guided resonance during forward and reverse rotation. The present invention provides the following technical solution: a single crystal multi-wire cutting machine roller, including a cylindrical body, a support cylinder is provided inside the cylindrical body, the support cylinder is coaxial with the cylindrical body and has the same length, and a plurality of connecting plates are uniformly fixedly arrayed on the outer side wall of the support cylinder, and the side of each connecting plate away from the support cylinder is fixedly connected to the inner side wall of the cylindrical body;

[0010] As a preferred embodiment of the present invention, a central tube is fixedly connected to the center of the connecting plate.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1 The present invention discloses a single crystal multi-wire cutting machine roller, including a cylinder body 1, a support cylinder 2 is provided inside the cylinder body 1, the support cylinder 2 is coaxial with the cylinder body 1 and has the same length, and a plurality of connecting plates 3 are uniformly fixedly arrayed on the outer side wall of the support cylinder 2, and the side of each connecting plate 3 away from the support cylinder 2 is fixedly connected to the inner side wall of the cylinder body 1.
[0020] Connecting components are also inserted into both ends of the cylinder 1. These connecting components are used to connect with the rotating mechanism of the single crystal multi-wire cutting machine.
[0021] The roller includes a cylinder body 1, a support cylinder 2 inside the cylinder body 1, and a connecting plate 3 connecting the support cylinder 2 and the cylinder body 1. Multiple connecting plates 3 are arranged in a uniform ring array. Through the above structure, it has the characteristics of compact structure, and it is not easy to vibrate during cutting, thereby improving the cutting accuracy and work efficiency.
[0022] Specifically, the connecting plate 3 extends along the axial direction of the cylinder 1 to the edge of the cylinder 1, and the cutting surface of the connecting plate 3 along the radial direction of the cylinder 1 is arc-shaped.
[0023] In this embodiment, the length of the connecting plate 3 is the same as the length of the cylinder 1, such as... Figure 1 and Figure 3 As shown, the connecting plate 3 is arc-shaped along the radial cut surface of the cylinder 1, forming a turbine-like structure. Compared with the traditional cylindrical structure, the structure is more compact and has higher reliability.
[0024] During the cutting process, the cylinder 1 needs to withstand the forces from the workpiece and the cutting force. The main stress is bending stress, that is, the cylinder 1 bends inward under force. The cylinder 1 is connected to the support cylinder 2 by the arc-shaped connecting plate 3 to form a turbine-like structure, which effectively disperses and buffers the bending stress, thereby improving the bending strength of the cylinder 1 and making it less prone to deformation, thus preventing it from shaking easily when rotating at high speed.
[0025] Specifically, the cylinder 1, the support cylinder 2, and the connecting plate 3 are integrally formed, and all three are made of carbon fiber.
[0026] In this embodiment, carbon fiber is used for manufacturing, which has high strength and lightweight characteristics. It can effectively reduce the weight of the roller and improve working efficiency. The roller made of carbon fiber is lightweight, has low inertia, and is not easily affected by external interference, thus reducing roller vibration.
[0027] During the cutting process, the cylinder 1 will also be subjected to shearing force from the workpiece. The cylinder is made of carbon fiber material, which has high strength and rigidity and can effectively withstand shear stress.
[0028] In addition, during the cutting process, the cylinder 1 will also be subjected to compressive force from the workpiece, which will generate compressive stress. Since carbon fiber material has high compressive strength and rigidity, it can effectively withstand compressive stress. At the same time, due to the compact structure of the roller, the impact of compressive stress on the roller can also be reduced, preventing vibration during high-speed rotation.
[0029] Specifically, such as Figure 2 As shown, the connecting component includes a connecting plate 4 and several insertion tubes 5. The insertion tubes 5 are arranged in a uniform ring array on one side of the connecting plate 4. A receiving cavity 6 is formed between every two connecting plates 3, the inner wall of the cylinder 1 and the outer wall of the support cylinder 2. The cross-section of the insertion tube 5 along the radial direction of the cylinder 1 and the cross-section of the receiving cavity 6 along the radial direction of the cylinder 1 are the same, and the number of insertion tubes 5 is the same as the number of receiving cavities 6.
[0030] In this embodiment, the insertion tube 5 can be inserted into the cavity 6. The cavity 6 is a through cavity formed by two adjacent connecting plates 3, the outer wall of the support cylinder 2, and the inner wall of the cylinder 1. The insertion tube 5 can be inserted into it and fit against the inner wall of the cavity 6. It is connected to the rotating shaft of the single crystal multi-wire cutting machine through the connecting plate 4, which facilitates columnar and disassembly effects. The rotating shaft will not directly contact the cylinder 1, which can reduce wear to a certain extent. At the same time, the insertion tube 5 can support the edge of the cylinder 1, which can prevent the edge of the cylinder 1 from sinking inward and causing vibration when the cylinder 1 rotates.
[0031] Specifically, a central tube 7 is fixedly connected to the center of the connecting plate 4. The connecting plate 4 is hollow, and the central tube 7 and the insertion tube 5 are located on the same side. The central tube 7 can be inserted into the interior of the support cylinder 2.
[0032] In this embodiment, the central tube 7 is inserted into the interior of the support cylinder 2 to support the edge of the support cylinder 2. Together with the insertion tube 5, it can enhance the connection strength with the roller structure, thereby reducing the vibration of the roller structure when rotating at high speed and improving accuracy.
[0033] Specifically, such as Figure 1 As shown, the connecting plate 4 has several insertion holes 8 on the side away from the insertion tube 5, and the insertion holes 8 are arranged in a circular array with the center of the connecting plate 4 as the center.
[0034] In this embodiment, the socket 8 facilitates the connection between the rotating shaft of the single crystal multi-wire cutting machine and the connecting plate 4, enhancing the connection strength and preventing vibration.
[0035] In summary, the single-crystal multi-wire cutting machine drum, by setting up a drum body 1, a connecting plate 3 and a support cylinder 2, with the connecting plate 3 having an arc along the radial direction of the drum body 1, has an overall turbine-like structure. This not only makes the drum structure more compact and stable, but also maximizes the cutting plane and can effectively withstand the effects of various stresses during cutting, thereby effectively reducing vibration and deformation during cutting and improving cutting accuracy and work efficiency.
