Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, specifically a multi-functional machine tool for laser cladding remanufacturing. Background Technology

[0002] Laser cladding technology refers to a process in which a selected coating material is placed on the surface of a substrate using different filler methods. The material is then irradiated with a laser to melt the coating material and a thin layer on the substrate surface simultaneously. After rapid solidification, a surface coating with extremely low dilution and metallurgical bonding with the substrate material is formed, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material surface.

[0003] Laser cladding remanufacturing machine tools generally only have laser cladding function. When performing laser cladding on rolls, in order to reduce the thermal stress between the roll substrate and the cladding layer and reduce the risk of cracking, it is often necessary to preheat the roll with external heating. In order to accelerate the cooling speed of the cladding layer, it is necessary to cool the cladding layer with external cooling equipment. External heating and cooling equipment increases the footprint of the overall processing equipment and will affect the overall processing smoothness and work efficiency. Therefore, it is urgent to improve this. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional machine tool for laser cladding remanufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional machine tool for laser cladding remanufacturing, comprising a machine tool body, a high-energy laser mounted on the top of the machine tool body, a support frame provided on the surface of the machine tool body, and a processor mounted inside the support frame via a rotating shaft, a second stepper motor mounted on the inner wall of one side of the support frame, and the output end of the second stepper motor fixedly connected to the rotating shaft, a heating cavity provided on the top of the processor, and infrared heaters with equal spacing mounted on the inner wall of the heating cavity, and a cooling cavity provided at the bottom of the processor, and a cooling fan mounted on the inner wall of the cooling cavity.

[0006] Preferably, clamping cylinders are installed on both sides of the surface of the machine tool body, and a clamping seat is installed at the output end of the clamping cylinder. A three-jaw chuck is installed on one side of the clamping seat through a bearing. The clamping cylinder drives the clamping seat to move the three-jaw chuck horizontally. The three-jaw chuck clamps both ends of the roll and then clamps and fixes both ends of the roll.

[0007] Preferably, a first stepper motor is installed inside the clamp, and the output end of the first stepper motor is fixedly connected to the three-grip chuck to facilitate driving the roller to rotate.

[0008] Preferably, a lead screw is mounted on the top of the machine tool body, and a servo motor is mounted on one side of the top of the machine tool body. The output end of the servo motor is fixedly connected to the lead screw, which passes through the top of the high-energy laser and engages with its thread. This facilitates driving the high-energy laser to translate.

[0009] Preferably, a lifting cylinder is installed inside the machine tool body below the support frame, and the output end of the lifting cylinder is fixedly connected to the support frame to facilitate driving the processor to lift it up and down.

[0010] Preferably, a powder preheating cylinder is installed on the outer wall of one side of the high-energy laser, and equally spaced heating wires are installed on the inner wall of the powder preheating cylinder. A powder inner cylinder is installed inside the powder preheating cylinder. The alloy powder passes through the powder inner cylinder inside the powder preheating cylinder and is heated by the heating wires to improve the flowability of the high-viscosity powder and improve the powder coverage effect.

[0011] Preferably, the processor has an X-shaped cross-section, and the inner surface of the heating cavity is a semi-circular arc surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A lifting cylinder drives the support frame to move upwards, causing the processor to move below the roll. The heating chamber on top of the processor faces upwards, and the roll is heated by an infrared heater, facilitating preheating of the roll, reducing thermal stress between the roll substrate and the cladding layer, and minimizing the risk of cracking. A servo motor drives the lead screw to rotate, causing the high-energy laser to slowly move along the roll. The high-energy laser beam generated by the high-energy laser heats the roll surface, rapidly heating and melting the roll substrate surface and the added alloy powder under thermal action. Upon cooling, a surface cladding layer with a very low dilution rate and a metallurgical structure with the substrate material is formed, extending the roll's service life and enabling reuse. This reduces roll consumption. Because a powder preheating cylinder is installed on one side of the high-energy laser, the alloy powder passes through the inner powder cylinder inside the preheating cylinder and is heated by heating wires, improving the flowability of the high-viscosity powder and enhancing the powder's coverage. After all the rolls have undergone laser cladding, the second stepper motor drives the rotating shaft to rotate the processor, causing the cooling chamber at the bottom of the processor to face upwards. The cooling fan then blows air onto the rolls to cool them, accelerating the cooling rate of the cladding layer. This machine tool has built-in roll preheating and cladding layer cooling functions, making it multifunctional. It requires no external equipment, improving overall processing smoothness and increasing work efficiency. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 One embodiment of this utility model is a multi-functional machine tool for laser cladding remanufacturing, comprising a machine tool body 1, wherein a high-energy laser 6 is mounted on the top of the machine tool body 1.

[0023] Specifically, the servo motor 7 drives the lead screw 5 to rotate, causing the high-energy laser 6 to slowly move along the roll. The high-energy laser beam generated by the high-energy laser 6 heats the surface of the roll. Under the action of heat, the surface of the roll substrate and the added alloy powder are rapidly heated and melted. After cooling, a surface cladding layer with a metallurgical structure with a very low dilution rate is formed, which extends the service life of the roll, enables reuse, and reduces roll consumption.

[0024] A support frame 9 is provided on the surface of the machine tool body 1, and a processor 12 is installed inside the support frame 9 via a rotating shaft 11. A second stepper motor 10 is installed on the inner wall of one side of the support frame 9, and the output end of the second stepper motor 10 is fixedly connected to the rotating shaft 11. A heating chamber 17 is provided on the top of the processor 12, and infrared heaters 18 with equal spacing are installed on the inner wall of the heating chamber 17. A cooling chamber 19 is provided on the bottom of the processor 12, and a cooling fan 20 is installed on the inner wall of the cooling chamber 19.

[0025] Specifically, after all the rolls have undergone laser cladding, the second stepper motor 10 drives the rotating shaft 11 to rotate the processor 12 so that the cooling chamber 19 at the bottom of the processor 12 faces upward. The cooling fan 20 runs to blow air onto the rolls to cool them down and accelerate the cooling rate of the cladding layer. This machine tool has built-in functions for preheating the rolls and cooling the cladding layer. It has multiple functions, requires no external equipment, improves the overall processing smoothness, and increases work efficiency.

[0026] Clamping cylinders 2 are installed on both sides of the surface of the machine tool body 1, and clamping seats 3 are installed at the output end of the clamping cylinders 2, and a three-grip chuck 4 is installed on one side of the clamping seat 3 via a bearing.

[0027] Specifically, the roll is placed between the three-grip chucks 4. The clamping cylinder 2 drives the clamping seat 3 to move the three-grip chucks 4 horizontally. The three-grip chucks 4 clamp the two ends of the roll and fix them. The first step motor 8 drives the three-grip chucks 4 to rotate, so that the roll rotates slowly. Next, the lifting cylinder 13 drives the support frame 9 to move upward, so that the processor 12 moves upward to below the roll. The heating chamber 17 on the top of the processor 12 faces upward, and the roll is heated by the infrared heater 18, which facilitates the preheating of the roll, reduces the thermal stress between the roll base and the cladding layer, and reduces the risk of cracking.

[0028] The first stepper motor 8 is installed inside the clamp 3, and the output end of the first stepper motor 8 is fixedly connected to the three-grip chuck 4;

[0029] A lead screw 5 is installed on the top of the machine tool body 1, and a servo motor 7 is installed on one side of the top of the machine tool body 1, and the output end of the servo motor 7 is fixedly connected to the lead screw 5.

[0030] A lifting cylinder 13 is installed inside the machine tool body 1 below the support frame 9, and the output end of the lifting cylinder 13 is fixedly connected to the support frame 9.

[0031] A powder preheating cylinder 14 is installed on the outer wall of one side of the high-energy laser 6, and equally spaced heating wires 15 are installed on the inner wall of the powder preheating cylinder 14, and a powder inner cylinder 16 is installed inside the powder preheating cylinder 14.

[0032] Furthermore, since a powder preheating cylinder 14 is installed on one side of the high-energy laser 6, the alloy powder passes through the powder inner cylinder 16 inside the powder preheating cylinder 14 and is heated by the heating wire 15, which improves the fluidity of the high-viscosity powder and improves the powder coverage effect.

[0033] The processor 12 has an X-shaped cross-section, and the inner surface of the heating cavity 17 is a semi-circular arc surface.

[0034] In this embodiment, the roll is first placed between three-grip chucks 4. The clamping cylinder 2 drives the clamping seat 3 to move the three-grip chucks 4 horizontally, clamping both ends of the roll. The roll is then fixed in place by the three-grip chucks 4. The first stepper motor 8 drives the three-grip chucks 4 to rotate, causing the roll to rotate slowly. Next, the lifting cylinder 13 drives the support frame 9 to move upwards, causing the processor 12 to move below the roll. The heating chamber 17 on top of the processor 12 faces upwards, and the roll is heated by the infrared heater 18, facilitating preheating of the roll, reducing thermal stress between the roll substrate and the cladding layer, and minimizing the risk of cracking. Then, the servo motor 7 drives the lead screw 5 to rotate, causing the high-energy laser 6 to move slowly along the roll. The high-energy laser beam generated by the high-energy laser 6 heats the surface of the roll, and under the effect of heat, heats the surface of the roll substrate and the added cladding layer. The gold powder is rapidly heated and melted, then cooled to form a surface cladding layer with a metallurgical structure and extremely low dilution rate, extending the service life of the rolls, enabling reuse, and reducing roll consumption. Because a powder preheating cylinder 14 is installed on one side of the high-energy laser 6, the alloy powder passes through the powder inner cylinder 16 inside the preheating cylinder 14 and is heated by the heating wire 15, improving the fluidity of the high-viscosity powder and enhancing the powder coverage. Finally, after all the rolls have undergone laser cladding, the second stepper motor 10 drives the rotating shaft 11 to rotate the processor 12, causing the cooling chamber 19 at the bottom of the processor 12 to face upwards. The cooling fan 20 then blows air onto the rolls to cool them, accelerating the cooling rate of the cladding layer. This machine tool has built-in roll preheating and cladding layer cooling functions, possessing multi-functional characteristics, requiring no external equipment, improving overall processing smoothness, and increasing work efficiency.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
