[0002] At present, wire saws are often used to cut large silicon rods, stones and other hard and brittle materials. Wire saw cutting technology has the advantages of narrow cutting slits, high efficiency, good slicing quality, and the ability to perform curved cutting. In the prior art, wire cutting equipment includes single-wire cutting equipment and wire mesh cutting equipment. Wire mesh cutting equipment, such as the existing patent number: CN115635600A, name: a new type of vertical diamond wire stone cutting equipment, adopts a wire mesh diamond wire cutting method, and the production efficiency and automation degree are improved. However, such wire mesh cutting equipment has the following problems: 1. For long wire cutting, there will be a difference in winding diameter between the two reel drums. In order to keep the tension unchanged, the rotation speeds of the two reel drums will also be inconsistent, causing the cutting wire to break; 2. Once the wire mesh diamond wire breaks, it will take a lot of time to repair, and the wire changing operation is troublesome; 3. The equipment can only cut one specification (thickness) of plate at a time, which cannot meet customer needs; 4. Since the hardness may be different inside the material to be processed, the existing wire mesh cutting cannot adjust the cutting speed and pressure of the diamond wire at that location according to the local hardness; 5. The wire mesh can only be cut by overall parallel movement, and the inclination angle between the diamond wire and the material cannot be adjusted. Utility Model Content

[0028] Example

[0029] Reference Figure 1 As shown, the utility model discloses a cutting device, including a base 10, a frame 20 is installed on the base 10, and a plurality of wheel groups 21 capable of retracting and releasing wires are respectively arranged on both sides of the frame. The frame 20 is in the shape of a door, and a mounting platform is horizontally extended outward on both sides of the frame 20. A plurality of support frames 201 are installed on the mounting platform, and the wheel groups 21 are installed on the support frames 201. A plurality of wheel groups 21 can be arranged vertically and horizontally on the support frames 201. The support frames 201 on both sides have the same structure, and the wheel groups 21 on the support frames 201 are symmetrical one by one. The material to be processed is not limited to large-volume stone and silicon materials, which are placed in the middle of the frame 20 and between the wheel groups 21 on both sides. In another embodiment, a fixing device is installed at the position where the material to be processed is placed in the middle of the frame 20, and the fixing device is a clamp for fixing the material to be processed.

[0030] Reference Figure 1-6As shown, the wheel set 21 includes a reel 211 and a torque motor 212. The torque motor 212 drives the reel 211 to reel or unreel. When the torque motor 212 on one side controls the reel 211 to reel, the torque motor 212 on the other side controls the reel 211 to unreel, so that the diamond wire is in constant tension to cut the material. The voltages of the two torque motors 212 are set, and the working voltage of one torque motor 212 is greater than the working voltage of the other torque motor 212. A larger torque is generated on the torque motor 212 with a larger voltage to drive the reel 211 to reel, while the other torque motor 212 with a smaller voltage provides a torque in the opposite direction to maintain a constant tension. The reel 211 is fixed with bolts. When a wire break occurs, the entire reel 211 is directly removed and replaced with a new one. The wire change speed is fast and the processing efficiency is high. The corresponding wire reel 211 on both sides of the frame 20 controls a diamond wire. There are multiple wire reel 211 on both sides of the frame 20. Each wire reel 211 has a separate torque motor 212 to control the wire reel. Multiple diamond wires form a mesh wire type, and at the same time, a single diamond wire can be controlled separately to cut the material to be processed. Compared with the existing control, it is more flexible. When the local hardness of the material to be cut is different, the software controls the separate torque motor 212 to increase the rotation speed to cut the local harder position, thereby improving the practicability of cutting.

[0031] Reference Figure 1-6 As shown, the wheel assembly 21 further includes a wire arrangement wheel 213 and a wire arrangement motor 214, and the wire arrangement motor 214 drives the wire arrangement wheel 213 to move through a first screw mechanism 215. Specifically, the diamond wire coming out of the wire reel 211 passes through the wire arrangement wheel 213, and when the wire reel 211 reels the wire, the wire arrangement motor 214 drives the wire arrangement wheel 213 to move back and forth along the wire reel 211, and evenly arranges the diamond wire on the wire reel 211, so as to prevent the diamond wire on the wire reel 211 from being disordered and unable to be discharged.

[0032] Reference Figure 1-6As shown, a pressing mechanism 22 which can move up and down is arranged in the middle of the frame 20, and the pressing mechanism 22 includes two guide rollers 221 which are arranged in parallel on the frame 20 and a pressure roller 222 which can move up and down, and a plurality of guide rings 223 are movably sleeved on the guide rollers 221 and the pressure rollers 222, and the diamond wire passes through the guide rollers 221, the pressure rollers 222 from the wheel set 21 at one end, and then to the pressure rollers 222, the guide rollers 221 and the wheel set 21 on the other side in sequence. Specifically, the guide roller 221 is fixed on the frame 20 above the pressure roller 222, and a guide ring 223 is set on the guide roller 221 and the pressure roller 222. The diamond wire passes through the guide ring 223. The second screw mechanism 225 and the mobile drive motor 224 are respectively arranged on both sides of the middle of the frame 20. The diamond wire goes from the guide roller 221 and the pressure roller 222 on one side to the pressure roller 222 and the guide roller 221 on the other side. The mobile drive motor 224 drives the pressure roller 222 to move up and down through the second screw mechanism 225, and drives the diamond wire to move up and down to cut the material. When the diamond wire needs to be horizontal When pressing down, the mobile drive motors 224 on both sides are controlled to drive the second screws on both sides and drive the pressure rollers 222 to press down at the same time. When it is necessary to adjust the angle between the diamond wire and the material to be processed, the second screw on one side is controlled to drive the mobile drive motor 224 to drive the pressure roller 222 on that side to be higher or lower than the pressure roller 222 on the other side, so that the diamond wire is in an inclined state to cut the material. Compared with the existing cutting equipment using an overall mesh type, the utility model can achieve the adjustment of multiple angles to adapt to materials of different fashions and adjust the cutting angle to improve the efficiency of cutting materials.

[0033] Furthermore, the pressing rollers 222 include four, with two pressing rollers 222 arranged on each side of the frame 20. Since the pressing rollers 222 drive the diamond wire to press down on the material, when the force on each pressing roller 222 is large, two pressing rollers 222 are used to drive the diamond wire to press down to increase the force area, thereby preventing the pressing rollers 222 from being damaged due to excessive force.

[0034] Reference Figure 1-6 As shown, each diamond wire passes through the guide ring 223 on the guide roller 221 and the pressure roller 222 on both sides respectively, and a partition is installed between the guide roller 221 and the guide ring 223 on the pressure roller 222. The distance between the two diamond wires is achieved by adjusting the thickness of the partition so as to be used for cutting and forming plates of different thicknesses. Compared with the traditional method of using a fixed guide wheel 2011: the same piece of material can only be processed into plates of the same specification (thickness), the utility model can cut a variety of plates of different specifications from the same piece of material according to customer needs, and is highly practical.

[0035] Reference Figure 1-6As shown, guide wheels 2011 are arranged above the wheel group 21 on both sides of the frame 20, and a plurality of guide grooves are provided on the guide wheels 2011. Specifically, a plurality of rows of take-up and pay-off drums 211 are arranged vertically on the support frame 201, and the guide wheels 2011 are installed on the upper end of the support frame 201. The diamond wires on the plurality of take-up and pay-off drums 211 in the same row in the vertical direction are guided from the guide wheels 2011 to the guide rings 223 on the guide rollers 221. The guide wheels 2011 further guide the diamond wires to avoid the equipment from being unable to work due to the entanglement of multiple diamond wires in the same vertical row on the support frame 201, thereby further improving the working stability of the equipment.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
