Description

Technical Field

[0001] The invention relates to the technical field of medal processing, and in particular to laser cutting equipment and a cutting process for medal processing. Background Art

[0002] Laser cutting is an advanced processing technology that uses a high-power, high-density laser beam to directly irradiate the material to be cut. When the laser beam contacts the material to be cut, the surface of the material quickly absorbs the laser energy and converts it into heat energy, causing the material temperature to quickly rise to the vaporization temperature. After reaching this temperature, the material begins to evaporate and form holes. By continuously moving the laser beam, the holes expand along the predetermined cutting path, ultimately achieving complete cutting of the material. This technology is widely used in various industrial fields due to its high precision, high efficiency and applicability to a variety of materials.

[0003] Medals, as a symbol of recognition and respect for winners of various competitions, are usually carefully made of metal or other solid materials. In the production process of medals, laser cutting is a key step. It accurately cuts the material according to the size requirements of the medal design. However, due to the size of the medal and the physical properties of the material, continuous laser cutting will cause the material used to make the medal to quickly increase in temperature during cutting. In this process, a heat-affected zone is often formed, which will cause the edge of the medal to deform and generate thermal stress inside. These deformations and thermal stresses not only affect the appearance of the medal, but may also reduce its structural strength and durability, thereby having a negative impact on the overall quality of the medal. Therefore, after laser cutting is completed, the medal usually needs to be subsequently reprocessed to eliminate or reduce the deformation and thermal stress caused by the heat-affected zone to ensure that the medal can maintain its flatness and aesthetics. This process will increase the cumbersomeness of the medal production process and the production cost. Therefore, it is necessary to provide a laser cutting device and cutting process for medal processing to solve the above technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide a laser cutting device and a cutting process for medal processing to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A laser cutting device for medal processing comprises a bottom frame, a rotating assembly, a rotary cutting assembly and a regulating and cooling assembly, wherein a mounting frame is fixedly installed on the top of the bottom frame, a placing frame is fixedly installed inside the mounting frame, two Y-axis servo modules are symmetrically fixedly installed on both sides of the bottom frame, two sliders are respectively installed on the output ends of the two Y-axis servo modules, a mounting frame is fixedly installed on one side of the two sliders, a Z-axis servo module is installed inside the top of the two mounting frames, a mounting plate is provided between the two Z-axis servo modules, and the two ends of the mounting plate are respectively installed and matched with the two Z-axis servo modules; the rotating assembly is used to adjust the positions of the rotary cutting assembly and the regulating and cooling assembly; the rotary cutting assembly comprises a mounting box installed on one of the output ends at the bottom end of the rotating assembly, a base is fixedly installed on the bottom end of the mounting box, a connecting column is rotatably connected to the center of the base, a rotary module is installed on the bottom end of the connecting column, and a laser cutting device is fixedly installed on one side of the rotary module; the regulating and cooling assembly is arranged below the rotating assembly, and the regulating and cooling assembly is installed on the other output end at the bottom end of the rotating assembly.

[0007] A further improvement of the technical solution of the present invention is that due to the size of the medal and the physical properties of the material, continuous laser cutting will cause the material used to make the medal to quickly increase in temperature during cutting. During this process, a heat-affected zone is often formed, which may cause the edge of the medal to deform and generate thermal stress inside. These deformations and thermal stresses not only affect the appearance of the medal, but may also reduce its structural strength and durability, thereby having a negative impact on the overall quality of the medal. Therefore, after the laser cutting is completed, the medal usually needs to be subsequently reprocessed to eliminate or reduce the deformation and thermal stress caused by the heat-affected zone to ensure that the medal can remain flat. degree and aesthetics, and this process will increase the complexity and production cost of the medal production process. In this solution, when starting the medal cutting process, the operator first places the material plate securely on the placement frame, and then the operator starts the equipment. At this time, the Z-axis servo module starts to work and accurately adjusts the working part of the device to the preset appropriate height. Once the working height is determined, the rotary cutting component starts to execute the laser cutting process and accurately laser cuts the material according to the set size. After completing the cutting of the first quarter of the circumference, the rotating component starts, which drives the rotary cutting component and the regulating and cooling component to rotate 180° clockwise, thereby exchanging their positions. At this time, the regulating and cooling component will perform air cooling on the previously cut position, which can quickly lower the temperature of the material, reduce the heat-affected area, and thereby prevent the edge of the medal from deforming due to high temperature. When the rotary cutting component moves to the original position of the regulating and cooling component, it will immediately start cutting again. After completing the cutting of the second quarter of a circle, the rotating component will start again, driving the rotary cutting component and the regulating and cooling component to rotate 180° counterclockwise and return to the initial position. At the same time, the cutting end of the rotary cutting component will also rotate counterclockwise by a quarter of a circle to ensure precise connection with the position where the knife stopped for the initial cutting, thereby continuing the cutting of the medal. This alternating cutting and cooling method not only improves the cutting efficiency, but also ensures the accuracy and quality of the medal cutting.

[0008] The above technical solution is adopted, and the rotating component includes a connecting ring, which is rotatably connected to the lower surface of the mounting plate, and the bottom end of the connecting ring is fixedly connected to the center of the upper surface of the horizontal plate, and a first motor is fixedly installed in the center of the upper surface of the mounting plate, and the output end of the first motor passes through the side wall of the mounting plate and is fixedly connected to the center of the upper surface of the horizontal plate, and two mounting blocks are symmetrically fixedly installed on the lower surface of the horizontal plate, and a bidirectional screw rod is rotatably connected between the two mounting blocks, and a second motor is fixedly installed on one side of one of the mounting blocks, and the output end of the second motor is fixedly connected to one end of the bidirectional screw rod, and two sliding seats are symmetrically threaded at both ends of the bidirectional screw rod, and the lower surface of the horizontal plate is slidably connected to the top of the two sliding seats; the mounting box is installed at the bottom end of a sliding seat.

[0009] The above-mentioned technical scheme is adopted, and the rotating assembly in the scheme also includes a fixed seat, which is fixedly installed in the center of the mounting plate, and a fixing frame is fixedly installed in the center of the upper surface of the fixed seat, and two working cylinders are symmetrically fixedly installed on the upper surface of the fixing frame, and the output ends of the two working cylinders pass through the side walls of the fixing frame and are fixedly connected to the upper surface of the lifting plate, and a plug-in rod is symmetrically fixedly installed on the lower surface of the lifting plate, and a matching hole for plugging and matching with the plug-in rod is opened on the upper surface of the cross plate.

[0010] A further improvement of the technical solution of the present invention is that: the working cylinder is started to push the lifting plate up. As the lifting plate rises, the connecting rod is pulled out of the matching hole on the upper surface of the horizontal plate, releasing the restriction on the horizontal plate. Then, the first motor starts working, driving the horizontal plate to rotate 180° clockwise, so that the regulating and cooling component moves to the cutting point and changes the position of the rotary cutting component. After that, the working cylinder is started again, so that the connecting rod is inserted into the matching hole on the upper surface of the horizontal plate. The second motor will drive the bidirectional screw to rotate as needed, and then adjust the position of the slide seat, so that the distance between the rotary cutting component and the regulating and cooling component can be adjusted in time.

[0011] The above technical solution is adopted, in which the placement frame is set at 45°.

[0012] A further improvement of the technical solution of the present invention is that the placement frame arranged at a 45° inclination can conveniently guide the gas ejected by the cooling component, thereby guiding the air leaking from the medal material into the bottom frame in an orderly manner, thereby increasing the flow rate of the air in the bottom frame.

[0013] The above-mentioned technical scheme is adopted, and the rotary cutting assembly in this scheme also includes a third motor, and the third motor is fixedly installed on one end of the upper surface of the base, and the base is internally rotatably connected with a rotating seat, and a groove wheel is fixedly installed on the lower surface of the rotating seat. A limiting rod is provided on one side of the groove wheel, and the limiting rod is fixedly connected to the rotating seat, and the base is internally rotatably connected with a pushing frame, and the pushing frame and the groove wheel are squeezed together, and one end of the connecting column extends through the side wall of the base to the interior of the base and is fixedly connected to the lower surface of the pushing frame.

[0014] A further improvement of the technical solution of the present invention is that: the laser cutting device performs precise circular cutting movement under the drive of the rotating module. When cutting to one-quarter of the circumference, the laser cutting device temporarily stops working. Subsequently, the rotary cutting component changes its position under the drive of the rotating component. Subsequently, the laser cutting device again performs precise cutting of one-quarter of the circumference under the drive of the rotating module. After completing this cutting work, the laser cutting device temporarily stops working again, and the rotating component drives the rotary cutting component back to the initial cutting position again. At this time, the third motor starts, and through the cooperation of the rotating seat, the groove wheel and the limiting rod, drives the pushing frame and the connecting column to rotate counterclockwise one-quarter of the circumference, and accurately brings the laser cutting device back to the stopping point of the initial cutting, ensuring a seamless connection of the cutting process.

[0015] The above-mentioned technical scheme is adopted, in which a limiting structure is installed on one side of the bottom end of the connecting column, and the limiting structure includes an electromagnet, a pressure ring and a matching ring. The electromagnet is fixedly installed on one side of the bottom end of the connecting column, and the bottom end of the connecting column is slidably sleeved with a pressure ring. The top end of the laser cutting device is fixedly installed with a matching ring, and the pressure ring and the matching ring are plugged into each other.

[0016] A further improvement of the technical solution of the present invention is that after the laser cutting device completes cutting of a quarter of a circle, the electromagnet starts to work, driving the pressure ring to press down, so that the pressure ring and the matching ring are plugged and matched with each other, thereby limiting the position of the laser cutting device.

[0017] The above-mentioned technical scheme is adopted, and the cooling component in the scheme includes a connecting frame, which is fixedly installed on the bottom end of another sliding seat, and a fourth motor is installed inside the connecting frame, and a connecting block is fixedly installed in the center of the bottom end of the connecting frame. The bottom end of the connecting frame is rotatably connected to a linear motor through the connecting block, and the output end of the fourth motor is fixedly connected to the upper surface of the linear motor through the side wall of the connecting frame, and a sliding seat is installed on the output end of the linear motor, and a mounting seat is fixedly installed on the bottom end of the sliding seat, and a bracket is rotatably connected to the outside of the mounting seat, and a blowing device is fixedly installed on the bottom end of the bracket.

[0018] The above-mentioned technical solution is adopted, and the cooling component in the solution also includes a fifth motor, which is fixedly mounted on one side of the mounting seat, and one end of the mounting seat is rotatably connected to a rotating gear, and a mating gear is provided on one side of the rotating gear, and the mating gear is rotatably connected to the inside of the mounting seat, and the rotating gear and the mating gear are meshed and connected, and the output end of the fifth motor passes through the side wall of the mounting seat and is fixedly connected to the rotating gear.

[0019] A further improvement of the technical solution of the present invention is that the air blowing device blows air to cool the cutting point. However, due to the uneven surface of the medal material, the cooling wind will be hindered to a certain extent. At this time, the sensor will capture these changes and transmit the information to the controller. Based on this information, the controller drives the linear motor to rotate through the fourth motor to adjust the blowing direction of the air blowing device. At the same time, the fifth motor drives the rotating gear and the matching gear to adjust the angle of the bracket and the air blowing device to ensure the maximum cooling effect. In addition, the linear motor controls the movement of the sliding seat. Through the drive of the linear motor, the sliding seat can move smoothly, thereby realizing the rapid change of the position of the air blowing device installed at the bottom of the sliding seat, so that the air blowing device can be flexibly adjusted to the optimal position to more effectively blow air to cool the material surface and ensure the stability and quality of the material during the processing.

[0020] The present invention also provides a laser cutting process for medal processing, comprising:

[0021] S1. Clean the surface of the placement frame and adjust its levelness to ensure the levelness and neatness of the cutting platform;

[0022] S2, after cleaning the material to be processed, place it on the placement frame and fix it with a positioning die holder, then rotate the cutting assembly and perform a tool alignment operation with the material to be processed;

[0023] S3, inputting the preset cutting program and cutting parameters into the laser cutting device, wherein the cutting parameters include the diameter of the medal, the spacing between the medals, and the arrangement of the medals;

[0024] S4, start the laser cutting device to cut the material to be processed, and at the moment of switching between the rotary cutting component and the cooling component, measure the temperature of the surface of the material to be processed, determine the relationship between the temperature and the set temperature, and adjust the distance between the rotary cutting component and the cooling component;

[0025] S5, the rotary cutting component then performs a quarter-circle cutting action, and upon completion, the cutting action stops immediately, and at the same time, the relative positions of the rotary cutting component and the cooling component are swapped by the rotating component.

[0026] Then, the rotary cutting component will start cutting again. At the same time, the cooling component will cool down the first position where the cutting has been completed. During the process, the blowing angle of the blowing device will be dynamically adjusted so that the temperature of the cutting edge is reduced to the set temperature range. When the cutting of a quarter of the circumference is completed at the second cutting position, the above steps are repeated until a circular cutting is completed.

[0027] S6. After the first cutting position completes a circular cutting operation, the Z-axis servo module will move the positions of the rotary cutting component and the cooling component according to the set medal arrangement parameters, thereby cutting the medal material again.

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0029] 1. The present invention provides a laser cutting device for medal processing. Through the setting of a rotary cutting component and according to the characteristics of the medal itself, the production material is accurately cut in sections. The cutting is stopped at each quarter of the circumference according to a preset program, and then the next cutting position is changed to perform the same quarter of the circumference cutting. This segmented cutting method is to ensure that the material will not heat up rapidly due to long-term laser irradiation during the cutting process, thereby avoiding deformation of the edge of the medal caused by the heat-affected area. Whenever a quarter of the circumference is cut, the component will pause, and the previous cutting position will be cooled to reduce the influence of thermal stress on the material. When the next cutting position completes a quarter of the circumference, the component will stop and the previous cutting position will be cooled to reduce the influence of thermal stress on the material. After cutting a circle, the rotary cutting assembly will return to the previous cutting position. During the return process, the laser cutting device is driven to rotate 90° counterclockwise through the precise coordination of the rotating seat, groove wheel, limiting rod and pushing frame. This step ensures that when the assembly returns to the previous cutting position, the laser cutting device can seamlessly connect with the trajectory of the previous cutting. This design greatly increases the cutting continuity of the rotary cutting assembly, making the entire laser cutting process smoother and more efficient. Through precise control and flexible adjustment, the rotary cutting assembly can better complete the laser cutting of the medal, ensuring that the edge of the medal is flat and the shape is precise, while reducing deformation problems caused by heat.

[0030] 2. The present invention provides a laser cutting device for medal processing. By adjusting the setting of a cooling component, the adverse effects of thermal stress on medal materials can be effectively reduced, and the edge smoothness and shape of the medal can be ensured. The cooling component can be adjusted to quickly and accurately reduce the heat generated by the rotary cutting component during the cutting process. The cooling component is equipped with an intelligent sensor and a controller, which can monitor the surface smoothness of the medal material in real time based on the feedback of the cooling air. Based on these real-time data, the sensor and the controller can quickly adjust the direction and blowing angle of the blowing device. This precise adjustment ensures that the cooling air can cover the material surface with the largest base area, thereby maximizing the cooling effect. It can not only effectively reduce the temperature of the cutting area, but also further reduce the risk of material deformation or damage due to thermal stress.

[0031] 3. The present invention provides a laser cutting device for medal processing. The rotating component can rotate the positions of the rotary cutting component and the regulating and cooling component 180° counterclockwise, ensuring high efficiency and accuracy during the processing. The rotating component maintains its own stability through the limiting structure when the rotary cutting component and the regulating and cooling component are working, which can ensure accurate cutting and cooling operations. Through the stable rotation of the rotating component and the precise control of the limiting structure, the rotary cutting component can accurately cut the medal, and the regulating and cooling component can cool the cutting point in real time during the cutting process to reduce the impact of thermal stress on the material. Such a design makes the medal processing process smoother and the quality of the finished product higher. The setting of the rotating component not only improves the efficiency of medal processing, but also ensures stability and accuracy during the processing, so that the medal can be better processed.

[0050] In this embodiment, when starting the medal cutting process, the operator first places the material plate securely on the placement frame 3, and then the operator starts the equipment. At this time, the Z-axis servo module 7 starts to work, and accurately adjusts the working part of the device to a preset appropriate height. Once the working height is determined, the rotary cutting component starts to execute the laser cutting process, and accurately laser cuts the material according to the set size. After completing the cutting of the first quarter of the circumference, the rotating component starts, which drives the rotary cutting component and the cooling component to rotate 180° clockwise, thereby exchanging their positions.

When the rotary cutting component moves to the original position of the regulating and cooling component, it will immediately start cutting again. After completing the cutting of the second quarter of a circle, the rotating component will start again, driving the rotary cutting component and the regulating and cooling component to rotate 180° counterclockwise and return to the initial position. At the same time, the cutting end of the rotary cutting component will also rotate counterclockwise by a quarter of a circle to ensure precise connection with the position where the knife stopped for the initial cutting, thereby continuing the cutting of the medal.

[0055] In this embodiment, the working cylinder 11 is started to push the lifting plate 12 up. As the lifting plate 12 rises, the connecting rod 13 is pulled out from the matching hole 14 on the upper surface of the horizontal plate 17, releasing the restriction on the horizontal plate 17. Then, the first motor 15 starts to work, driving the horizontal plate 17 to rotate 180° clockwise, so that the regulating and cooling component moves to the cutting point and changes the position of the rotary cutting component.

[0061] like Figure 7 and Fig.12 As shown, preferably, a limiting structure is installed on one side of the bottom end of the connecting column 29, and the limiting structure includes an electromagnet 43, a pressure ring 44 and a matching ring 45. The electromagnet 43 is fixedly installed on one side of the bottom end of the connecting column 29, and the bottom end of the connecting column 29 is slidably sleeved with a pressure ring 44. The top end of the laser cutting device 31 is fixedly installed with a matching ring 45, and the pressure ring 44 and the matching ring 45 are plugged in and matched with each other.

[0062] In this embodiment, after the laser cutting device 31 completes cutting of a quarter of a circle, the electromagnet 43 starts to work, driving the pressure ring 44 to press down, so that the pressure ring 44 and the matching ring 45 are plugged into and matched with each other, thereby limiting the position of the laser cutting device 31 and preventing the laser cutting device 31 from rotating randomly when the rotary cutting assembly is adjusting its position.

[0063] It should be noted that: the regulating and cooling component is equipped with a sensor and a controller. The sensor is used to collect feedback information when the wind is obstructed, and the controller can adjust the regulating and cooling component according to the actual feedback information, so that the regulating and cooling component can better cool the material.

[0064] Example 4

[0065] like Fig.10 and Fig.11 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the cooling component includes a connecting frame 32, the connecting frame 32 is fixedly mounted on the bottom end of another slide 21, a fourth motor 33 is installed inside the connecting frame 32, a connecting block 34 is fixedly mounted at the center of the bottom end of the connecting frame 32, the bottom end of the connecting frame 32 is rotatably connected to a linear motor 35 through the connecting block 34, the output end of the fourth motor 33 is fixedly connected to the upper surface of the linear motor 35 through the side wall of the connecting frame 32, a sliding seat 36 is installed at the output end of the linear motor 35, a mounting seat 37 is fixedly mounted at the bottom end of the sliding seat 36, a bracket 41 is rotatably connected to the outside of the mounting seat 37, and a blowing device 42 is fixedly mounted at the bottom end of the bracket 41;

[0066] The cooling component also includes a fifth motor 38, which is fixedly mounted on one side of the mounting seat 37. A rotating gear 39 is rotatably connected to one end of the mounting seat 37. A mating gear 40 is provided on one side of the rotating gear 39, and the mating gear 40 is rotatably connected to the inside of the mounting seat 37. The rotating gear 39 and the mating gear 40 are meshedly connected. The output end of the fifth motor 38 passes through the side wall of the mounting seat 37 and is fixedly connected to the rotating gear 39.

[0067] In this embodiment, the blowing device 42 blows air to cool the cutting point. However, due to the uneven surface of the medal material, the cooling air will be hindered to a certain extent. At this time, the sensor will capture these changes and transmit the information to the controller. Based on this information, the controller drives the linear motor 35 to rotate through the fourth motor 33 to adjust the blowing direction of the blowing device 42. At the same time, the fifth motor 38 drives the rotating gear 39 and the matching gear 40 to adjust the angle of the bracket 41 and the blowing device 42 to ensure that the cooling effect is maximized. In addition, the linear motor 35 controls the movement of the sliding seat 36. Through the drive of the linear motor 35, the sliding seat 36 can move smoothly, thereby realizing the rapid change of the position of the blowing device 42 installed at the bottom of the sliding seat 36, so that the blowing device 42 can be flexibly adjusted to the optimal position to more effectively blow air to cool the surface of the material and ensure the stability and quality of the material during the processing.

[0068] It should be noted that: the regulating and cooling component is equipped with a sensor and a controller. The sensor is used to collect feedback information when the wind is obstructed, and the controller can adjust the regulating and cooling component according to the actual feedback information, so that the regulating and cooling component can better cool the material.

[0069] The present invention also provides a laser cutting process for medal processing, comprising the following steps:

[0070] S1. Clean the surface of the placement frame and adjust its levelness to ensure the levelness and neatness of the cutting platform;

[0071] S2, after cleaning the material to be processed, place it on the placement frame and fix it with a positioning die holder, then rotate the cutting assembly and perform a tool alignment operation with the material to be processed;

[0072] S3, inputting the preset cutting program and cutting parameters into the laser cutting device, wherein the cutting parameters include the diameter of the medal, the spacing between the medals, and the arrangement of the medals;

[0073] S4, start the laser cutting device to cut the material to be processed, and at the moment of switching between the rotary cutting component and the cooling component, measure the temperature of the surface of the material to be processed, determine the relationship between the temperature and the set temperature, and adjust the distance between the rotary cutting component and the cooling component;

[0074] The spacing refers to the distance between the cutting position and the cooling position, to avoid the distance between the two being too small, which will cause temperature accumulation and affect the cooling effect;

[0075] S5, the rotary cutting component then performs a quarter-circle cutting action, and upon completion, the cutting action stops immediately, and at the same time, the relative positions of the rotary cutting component and the cooling component are swapped by the rotating component.

[0076] Then, the rotary cutting component will start cutting again. At the same time, the cooling component will cool down the first position where the cutting has been completed. During the process, the blowing angle of the blowing device will be dynamically adjusted so that the temperature of the cutting edge is reduced to the set temperature range. When the cutting of a quarter of the circumference is completed at the second cutting position, the above steps are repeated until a circular cutting is completed.

[0077] S6. After the first cutting position completes a circular cutting operation, the Z-axis servo module will move the positions of the rotary cutting component and the cooling component according to the set medal arrangement parameters, thereby cutting the medal material again.

[0078] The following is a detailed description of the working principle of the laser cutting equipment used for medal processing.

[0079] like Figure 1-13As shown, before starting the cutting work, the operator first places the material plate securely on the placement frame 3, then the machine is activated, and the Z-axis servo module 7 starts to automatically adjust the height of the working part of the device to ensure that it is in the best working position. Once the working height is determined, the rotary cutting assembly starts the laser cutting process. The laser cutting device 31 is driven by the rotating module 30 to perform precise circular cutting movement. When cutting to a quarter of the circumference, the laser cutting device 31 temporarily stops working. At the same time, the electromagnet 43 starts to work, driving the pressure ring 44 to The pressure ring 44 and the matching ring 45 are pressed down, so that the pressure ring 44 and the matching ring 45 are plugged and matched with each other, so as to limit the position of the laser cutting device 31 and prevent the laser cutting device 31 from rotating randomly when the rotary cutting assembly is adjusting its position. At this time, the working cylinder 11 is started to push the lifting plate 12 up. As the lifting plate 12 rises, the plug-in rod 13 is pulled out of the matching hole 14 on the upper surface of the horizontal plate 17, releasing the restriction on the horizontal plate 17. Then, the first motor 15 starts to work, driving the horizontal plate 17 to rotate 180° clockwise, so that the cooling assembly moves to the cutting point.

[0080] Subsequently, the cooling component is quickly put into operation, and the air blowing device 42 blows air to cool the cutting point. However, due to the uneven surface of the medal material, the cooling air will be hindered to a certain extent. At this time, the sensor will capture these changes and transmit the information to the controller. According to this information, the controller drives the linear motor 35 to rotate through the fourth motor 33 to adjust the blowing direction of the air blowing device 42. At the same time, the fifth motor 38 drives the rotating gear 39 and the matching gear 40 to adjust the angle of the bracket 41 and the air blowing device 42 to ensure the maximum cooling effect.

[0081] While the cooling component is adjusted to cool the material, the rotary cutting component continues its cutting work. When the rotary cutting component completes cutting of a quarter of a circle again, the rotating component drives the entire system to rotate 180° counterclockwise, so that the rotary cutting component returns to the initial cutting position. At this time, the third motor 24 is started, and through the cooperation of the rotating seat 25, the groove wheel 26 and the limiting rod 27, the driving frame 28 and the connecting column 29 are driven to rotate a quarter of a circle counterclockwise, and the laser cutting device 31 is accurately brought back to the stopping point of the initial cutting, ensuring a seamless connection of the cutting process;

[0082] In addition, since different materials have different thermal conductivity coefficients, the second motor 20 will drive the bidirectional screw 19 to rotate as needed, and then adjust the position of the slide 21, so that the distance between the rotary cutting component and the cooling component can be adjusted in time to meet the processing requirements of different materials. This flexible adjustment mechanism ensures that the device can perform cutting processing in segments, greatly improving processing efficiency and material utilization.

[0083] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
