[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a slow-feeding wire processing machine with cooling and dustproof functions, comprising a machine body 1 and a connecting rod 11, a hollow frame 3 is fixedly connected to the top front side of the machine body 1, and hollow plates 4 are fixedly connected to the left and right ends of the bottom inner side of the hollow frame 3, and a bidirectional screw rod 5 is rotatably connected to the front side of the hollow plate 4, and the rear end of the bidirectional screw rod 5 passes through the hollow plate 4, and the front and rear sides of the outer walls of the two bidirectional screw rods 5 are threadedly connected to movable blocks 6, and one side of the movable block 6 is rotatably connected to a first rotating shaft 7, and a clamping plate 8 is provided on the adjacent sides of the two hollow plates 4, and the front and rear ends of the two clamping plates 8 that are away from each other are fixedly connected to a U-shaped plate 9, and the inside of the U-shaped plate 9 is rotatably connected to a second rotating shaft 10, and multiple second rotating shafts 10 are respectively connected to the corresponding first rotating shaft 7 through the connecting rod 11, and the left and right sides of the inner wall of the hollow frame 3 are connected to the second rotating shaft 10, and the second rotating shafts 10 are respectively connected to the corresponding first rotating shaft 7 through the connecting rod 11. A servo motor 12 is fixedly connected to the side, and a rotating rod 13 is fixedly connected to the output end of the servo motor 12. The bottom end of the rotating rod 13 passes through the hollow plate 4 and is fixedly connected to a driving bevel gear 14. A driven bevel gear 15 is fixedly connected to the middle of the outer wall of the left bidirectional screw rod 5. The driven bevel gear 15 is meshed and connected with the driving bevel gear 14. A transmission assembly is arranged on the front side of the outer wall of the bidirectional screw rod 5. A cooling mechanism 2 is arranged on the right side of the hollow frame 3. A groove 19 is opened on the front side of the body 1. A processing head 20 is slidably connected inside the groove 19. A plurality of movable blocks 6 are respectively slidably connected to the corresponding inside of the hollow plate 4. The transmission assembly includes a pulley 16 and a transmission belt 22. The two pulleys 16 are respectively fixedly connected to the front sides of the outer walls of the corresponding bidirectional screw rod 5. The two pulleys 16 are connected by a transmission belt 22.

[0030] Specifically, the servo motor 12 can drive the rotating rod 13 to perform precise rotational motion, and the active bevel gear 14 installed on the rotating rod 13 will rotate together, and the driven bevel gear 15 will also rotate to drive the left bidirectional screw 5 to start rotating. When the left bidirectional screw 5 rotates, the right bidirectional screw 5 will also rotate in a synchronous manner through the drive belt 22, thereby ensuring the high consistency of the two bidirectional screws 5 during operation. As the two bidirectional screws 5 rotate, the movable blocks 6 on them will move toward the middle, and this action will drive the first rotating shaft 7 to start rotating, which is closely connected to the second rotating shaft 10 through the connecting rod 11. Therefore, when the first rotating shaft 7 rotates, the second rotating shaft 10 will also rotate with it. This design cleverly realizes the linkage between the two rotating shafts, making the movement of the entire mechanical device more coordinated and smooth. As the second rotating shaft 10 rotates, it will drive the clamps 8 on both sides to move toward the middle. These two clamps 8 are specially designed to clamp the workpiece to be processed. When they move toward the middle, they will clamp the workpiece tightly, thus effectively preventing the workpiece from shaking or deflecting due to interference from external factors during processing. This stable clamping method not only ensures the processing quality of the workpiece, but also greatly improves the processing efficiency and meets the needs of users.

[0031] Reference Figure 1 and Figure 2 The cooling mechanism 2 includes a refrigeration unit 201, which is fixedly connected to the right side of the hollow frame 3. The top of the refrigeration unit 201 is connected to a connecting hose 202. A T-shaped slot 203 is provided at the rear side of the hollow frame 3. A T-shaped aeration pipe 204 is fixedly connected to the inside of the T-shaped slot 203. A plurality of aeration holes 205 are equidistantly provided at the front side of the T-shaped aeration pipe 204. The left end of the connecting hose 202 is connected to the top of the T-shaped aeration pipe 204.

[0032] Specifically, during the wire-cutting process, the friction between the tool and the workpiece will generate a large amount of heat. In order to avoid the adverse effects of this heat on the workpiece, such as thermal deformation or thermal stress, we need to continuously inject cooling water into the hollow frame 3 during the processing. These cooling waters circulate and quickly take away the heat generated during the processing, thereby effectively reducing the temperature of the workpiece and ensuring the stability and accuracy of the processing. During the long processing, the temperature of the cooling water will gradually increase, thereby reducing its cooling effect. At this time, the generated cold air is transported to the hollow frame 3 through the refrigeration unit 201, and the aeration holes 205 are the channels for the cold air to enter the hollow frame 3. Through them, the cold air can be evenly distributed in the cooling water, thereby quickly and effectively reducing the temperature of the cooling water.

[0033] Reference Figure 1A control cabinet 17 is fixedly connected to the right side of the machine body 1, and a control panel 18 is arranged on the front side of the control cabinet 17. The control panel 18 is electrically connected to the refrigeration unit 201, the servo motor 12 and the processing head 20 respectively;

[0034] Specifically, the operation of the refrigeration unit 201 , the servo motor 12 and the processing head 20 can be controlled through the control panel 18 .

[0035] Reference Figure 1 , an observation window 21 is provided on the front side of the hollow frame 3;

[0036] Specifically, the observation window 21 can facilitate the staff to check the internal conditions of the hollow frame 3 at any time, and can respond in time when encountering special situations.

[0037] Working principle: When using the device, the size of the workpiece to be processed can be observed, and then it can be placed in the hollow frame 3. Subsequently, the servo motor 12 can drive the rotating rod 13 to rotate, and the active bevel gear 14 on the rotating rod 13 will rotate accordingly. The driven bevel gear 15 will also rotate due to the engagement with the active bevel gear 14, thereby driving the left-side bidirectional screw rod 5 to rotate. The pulley 16 on the bidirectional screw rod 5 will drive the right-side bidirectional screw rod 5 to rotate through the transmission belt 22. At this time, the movable blocks 6 on the two bidirectional screw rods 5 will move toward the middle, the first rotating shaft 7 will rotate accordingly, and the second rotating shaft 10 will also rotate through the connecting rod 11, thereby driving the clamping plates 8 on both sides to move toward the middle to limit the clamping of the workpiece to be processed. It is not easily affected by external factors and causes shaking and deviation during processing, thereby ensuring the processing quality of the workpiece and meeting the needs of users. After the workpiece clamping work is completed, cooling water is first injected into the hollow frame 3. The function of the cooling water is to cool down the heat generated by the slow wire cutting processing, and at the same time, it can prevent the impurities generated by the processing from affecting the health of the workers. The temperature of the cooling water tends to become high after long-term use. At this time, cold air can be input into the T-type aeration pipe 204 through the refrigeration unit 201, and the cold air will then enter the hollow frame 3 through the aeration hole 205. The cooling water in the hollow frame 3 can be cooled, thereby ensuring the processing stability and accuracy of the workpiece, thereby improving the practicality of the device.
