[0003] Currently, the existing dual-head CNC silicon rod cutting machine is cumbersome and time-consuming to change the cutting blade when cutting different materials. It requires the use of various disassembly and assembly tools, which reduces processing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the replacement steps of the cutting blades in the existing dual-head CNC silicon rod cutting machine are cumbersome and time-consuming when changing the cutting blades to cut different materials.

[0005] To solve the above problems, this utility model provides a double-head CNC silicon rod cutting machine, including a cutting machine body. A processing box is fixedly connected inside the cutting machine body. A pair of rectangular plates are fixedly connected to the inner top wall of the processing box. The pair of rectangular plates are rotatably connected to the same connecting shaft. A pair of sleeve rings are fixedly sleeved on the outer end of the connecting shaft. Multiple cutting blades are fixedly connected to the outer end of the sleeve rings. Semicircular blocks are fixedly connected to the ends of the pair of rectangular plates that are close to each other. Vertical tubes are threadedly connected to the interior of the semicircular blocks. Multiple insertion slots are opened on the outer end of the connecting shaft to be movably inserted into the vertical tubes.

[0006] In the aforementioned dual-head CNC silicon rod cutting machine, the replacement of the cutting blade is simple and time-saving, thereby improving processing efficiency.

[0007] As a further improvement of this application, in the initial state, the lower end of the vertical tube is movably inserted into the insertion slot, and the outer end of the cutting blade is fitted with a protective cover.

[0008] As a further improvement to this application, the protective cover is magnetically connected to the cutting blade through a magnetic coating, and the side end of the protective cover contacts the outer end of the sleeve ring.

[0009] As a further improvement of this application, a rotating head is fixedly connected to the upper end of the vertical tube, and the outer end of the rotating head is engraved with anti-slip texture.

[0010] As another improvement of this application, a pair of rectangular plates are provided with transverse grooves at their close ends. An electric push rod is fixedly connected to the inner wall of the transverse groove. A connecting ring is fixedly connected to the telescopic end of the electric push rod. The connecting ring is rotatably sleeved on the connecting shaft. A pair of cooling boxes are fixedly connected to the inner top wall of the processing box. A cooling groove is provided at the end of the cooling box near the connecting ring, which is movably inserted into the cutting blade.

[0011] As a further improvement to this application, a water pipe is fixedly connected to the outer end of the cooling box, and a sealing cap is fitted onto the outer end of the water pipe. In the initial state, there is a gap between the protective cover and the cooling box.

[0012] As a further improvement to this application, the inner wall of the connecting shaft is provided with multiple sliding grooves, and the inside of the sliding grooves is rotatably connected with balls, and the side end of the connecting shaft is rotatably inserted into the inside of the transverse groove.

[0013] 1. When changing the cutting blade and using it to cut different materials, the rotating head needs to be manually rotated to remove the lower end of the vertical tube from the insertion slot, thereby releasing the limiting position on the connecting shaft. Then, the connecting shaft is rotated to make it rotate together with the cutting blade to select the required cutting blade. After rotating the required cutting blade to be directly below the sleeve ring, the vertical tube is reset so that one end enters the corresponding insertion slot to fix the connecting shaft and thus the cutting blade. This completes the cutting blade replacement operation. Therefore, the cutting blade replacement process of this cutting machine is simple and time-saving, thereby improving processing efficiency.

[0014] 2. After cutting, when cooling down the heated cutting blade, the lower end of the vertical pipe should be removed from the insertion slot. Then, rotate the connecting shaft to rotate the used cutting blade directly above the connecting ring. At the same time, both ends of the connecting shaft will rotate inside the connecting ring. Then, start the electric push rod to pull the connecting ring and the connecting shaft together towards the cooling box, thereby moving the cutting blade towards the cooling box until it is inserted into the cooling tank. Then, use the cooling box to cool down the cutting blade to prevent damage due to excessive temperature. Attached Figure Description

Detailed Implementation

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figure 1-5 A dual-head CNC silicon rod cutting machine is shown, including a cutting machine body 1. A processing box 2 is fixedly connected inside the cutting machine body 1. A pair of rectangular plates 3 are fixedly connected to the inner top wall of the processing box 2. The pair of rectangular plates 3 are rotatably connected to the same connecting shaft 4. A pair of sleeve rings 5 ​​are fixedly sleeved on the outer end of the connecting shaft 4. Multiple cutting blades 6 are fixedly connected to the outer end of the sleeve rings 5. Semicircular blocks 7 are fixedly connected to the ends of the pair of rectangular plates 3 that are close to each other. Vertical tubes 8 are threadedly connected inside the semicircular blocks 7. Multiple insertion slots 9 are opened on the outer end of the connecting shaft 4 to be movably inserted into the vertical tubes 8.

[0025] In the initial state, the lower end of the vertical tube 8 is movably inserted into the insertion slot 9, and the outer end of the cutting blade 6 is fitted with a protective cover 10. When replacing the cutting blade 6, the protective cover 10 needs to be removed from the cutting blade 6. The protective cover 10 can protect the operator and the cutting blade 6, thereby preventing the cutting blade 6 from scratching the operator. The protective cover 10 is magnetically connected to the cutting blade 6 through the magnetic coating 11. The side end of the protective cover 10 is in contact with the outer end of the sleeve ring 5. The upper end of the vertical tube 8 is fixedly connected to a rotating head, and the outer end of the rotating head is engraved with anti-slip texture.

[0026] When changing the cutting blade 6 and using it to cut different materials, the rotating head needs to be manually rotated to remove the lower end of the vertical tube 8 from the insertion slot 9 to release the restriction on the connecting shaft 4. Then, the connecting shaft 4 is rotated to make it rotate together with the cutting blade 6 to select the required cutting blade 6.

[0027] After rotating the required cutting blade 6 to directly below the sleeve ring 5, reset the vertical tube 8 so that one end enters the corresponding insertion slot 9 to fix the connecting shaft 4, thereby fixing the cutting blade 6 and completing the operation of replacing the cutting blade 6. Therefore, when replacing the cutting blade 6, the replacement steps of this cutting machine are simple and time-saving, thereby improving processing efficiency.

[0028] Second implementation method:

[0029] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0030] Figure 2 and Figure 5 A pair of rectangular plates 3 are shown with horizontal grooves 12 at their close ends. An electric push rod 13 is fixedly connected to the inner wall of the horizontal groove 12. A connecting ring 14 is fixedly connected to the telescopic end of the electric push rod 13. The connecting ring 14 is rotatably sleeved on the connecting shaft 4. A pair of cooling boxes 15 are fixedly connected to the inner top wall of the processing box 2. The cooling boxes 15 are filled with coolant. Through temperature conduction, the overall temperature of the cooling boxes 15 is reduced. A cooling groove 16 is opened at the end of the cooling box 15 near the connecting ring 5, which is movably inserted into the cutting blade 6.

[0031] A water pipe 17 is fixedly connected to the outer end of the cooling box 15. A sealing cap is fitted on the outer end of the water pipe 17. In the initial state, there is a gap between the protective cover 10 and the cooling box 15. Multiple sliding grooves are opened on the inner wall of the connecting shaft 4. A ball bearing 18 is rotatably connected inside the sliding groove. The ball bearing 18 can reduce the friction force on the connecting shaft 4 when it rotates in the connecting ring 14. The side end of the connecting shaft 4 is rotatably inserted into the transverse groove 12.

[0032] After cutting is completed, when cooling down the heated cutting blade 6, the lower end of the vertical tube 8 needs to be removed from the insertion slot 9. Then, rotate the connecting shaft 4 to rotate the used cutting blade 6 directly above the sleeve ring 5. At the same time, both ends of the connecting shaft 4 will rotate within the connecting ring 14.

[0033] Then, the electric push rod 13 is activated, causing its telescopic end to pull the connecting ring 14 and the connecting shaft 4 together to move towards the cooling box 15, thereby moving the cutting blade 6 towards the cooling box 15 until the cutting blade 6 is inserted into the cooling tank 16. Then, the cooling box 15 is used to cool down the cutting blade 6, thereby preventing damage due to excessive temperature of the cutting blade 6.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
