Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire cutting technology, specifically a traction system for a diamond wire cutting machine. Background Technology
[0002] Diamond wire cutting equipment utilizes diamond wire saws as cutting consumables to cut materials such as marble, jade, monocrystalline silicon, and semiconductors. In actual use, diamond wire is tightly wound onto take-up and unwinding reels. A servo motor drives the take-up and unwinding reels and traction wheel to reciprocate at high speed, forming a diamond wire mesh together with the wire laying system and tension system. This achieves the reciprocating cutting of the material. Typically, the cutting machine's traction system is driven by a servo motor to balance the load on the diamond wire mesh and synchronously control its movement with the take-up and unwinding system, enabling the diamond wire mesh to reciprocate at high speed and achieve high-speed cutting of the material.
[0003] A search revealed a Chinese utility model patent with publication number CN118527733A, which discloses a multi-wire cutting machine, including diamond wire, a first cutting wheel group, a cutting rotary wheel group, a second cutting wheel group, and a cutting drive mechanism. This patent uses a servo motor traction shaft to balance the load during the cutting process. However, when performing large-size or heavy-load cutting, the traction shaft is prone to slippage, significantly reducing the lifespan of the cutting wheels. The traction system and the wire take-up and unwinding system cannot operate synchronously, greatly reducing the stability of the wire mesh, exacerbating the vibration of the traction arm, and significantly increasing the wire breakage rate. The application of multiple servo systems in the cutting system also indirectly increases the overall system cost and results in a large footprint, failing to meet current requirements. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a traction system for a diamond wire cutting machine. The main solution is to address the issues that, during large-size or heavy-load cutting, the traction shaft easily slips, significantly reducing the lifespan of the cutting wheel. Furthermore, the traction system and the wire take-up / delivery system cannot operate synchronously, greatly reducing the stability of the wire mesh, exacerbating the vibration of the traction arm, and significantly increasing the wire breakage rate. The application of multiple servo systems in the cutting system also indirectly increases the overall system cost and contributes to its large footprint.

[0008] A traction system for a diamond wire cutting machine includes a base, diamond wire, and a placement frame. A support frame is fixedly connected to the top of the base. An inlet wheel and an outlet wheel are rotatably connected to the top two sides of the support frame, and an encoder is provided on one side of the outlet wheel. A first tension adjustment component and a second tension adjustment component are provided on both sides of one end of the support frame. Both the first tension adjustment component and the second tension adjustment component include a fixed bracket.

A first cutting wheel and a conversion wheel are rotatably connected to both sides of the first sliding frame, and a second cutting wheel is rotatably connected to both sides of the second sliding frame.
[0010] Based on the aforementioned scheme, the diamond wire is led out by the first take-up and unwinding system, passes through the first tension adjusting component, is introduced by the inlet wheel, winds around the second cutting wheel and extends to the first cutting wheel, then changes direction by the changeover wheel, and winds around the first cutting wheel and extends to the second cutting wheel. After winding, the diamond wire is led out by the outlet wheel, passes through the second tension adjusting component, and is taken in by the second take-up and unwinding system.
[0011] As a further embodiment of this utility model, both sides of the support frame are rotatably connected to lead screws, and the outer surfaces of the lead screws are threadedly connected to the first sliding frame and the second sliding frame. Both sides of the support frame are fixedly connected to a first servo motor, and the output shaft of the first servo motor is keyed to one end of the lead screw.
[0012] Furthermore, in the first tension adjustment assembly, the diamond wire is wound sequentially along the fixed wheel, the second tension wheel, and the first tension wheel.
[0013] Based on the aforementioned scheme, in the second tension adjustment assembly, the diamond wire is wound sequentially along the first tension wheel, the second tension wheel, and the fixed wheel.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a traction system for a diamond wire cutting machine, which has the following advantages:
[0019] 1. This utility model eliminates the traditional traction servo motor and adds a high-precision encoder to the output wheel as a constant speed wheel to control the smooth operation of the entire wire network. This prevents the traction shaft from slipping during the overall operation of the equipment, thereby greatly extending the life of the traction shaft. Furthermore, the use of a high-precision encoder to replace the traction servo motor also reduces the overall system cost.
[0020] 2. This utility model, through the setting of tension servo motor and tension swing arm, controls the first tension wheel and the second tension wheel respectively, changing the traditional active tension control system to a tension control system that combines active and passive control. Due to the adoption of the tension control method that combines active and passive control, the defect of tension smooth control that cannot be achieved in the original system is avoided, effectively reducing the shaking of the wire mesh and tension arm, thereby effectively reducing the wire mesh breakage rate and improving product quality.
[0021] 3. By changing the original horizontal placement of the first and second wire take-up and take-up systems to a vertical placement, this utility model can greatly reduce the space occupied and improve the stable output and input of diamond wire. Attached Figure Description
