The requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. A steel cutting machine is a device that can automatically transport, cut, and discharge steel. The use of a steel cutting machine can greatly improve the cutting efficiency of steel.

[0003] For example, CN 222221473 U discloses a steel cutting machine, including a first base plate and a cutting assembly. The cutting assembly includes a first mounting ring, a second mounting ring, and a laser emitter. The first mounting ring is mounted on the first base plate, and the axis of the first mounting ring is parallel to the steel transport direction. The second mounting ring is coaxially rotatably connected to the first mounting ring. The laser emitter is mounted on the second mounting ring, and the laser emitted by the laser emitter is perpendicular to the axis of the second mounting ring. The steel cutting machine is designed such that while the steel passes through the second mounting ring, the laser emitted by the laser emitter cuts the steel. At the same time, the second mounting ring rotates on the first mounting ring, increasing the degree of change in the cutting angle, thereby cutting irregular kerfs.

[0004] In the actual use of the above case, when limiting the cutting steel, it is necessary to make constant manual adjustments to ensure stable limiting of the steel. This operation method is relatively troublesome and cannot meet the current needs. Therefore, this utility model provides a laser cutting machine for steel. Utility Model Content

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a laser cutting machine for steel, including a base 1 and a steel body 5. A support frame 2 is provided at the center of the top of the base 1. A laser cutting assembly 3 for cutting steel is provided inside the support frame 2. The laser cutting assembly 3 includes a rotary motor 301 fixedly connected to the top of the support frame 2. A fixed ring 302 is fixedly connected to the output shaft of the rotary motor 301. An inner ring 303 is rotatably connected inside the fixed ring 302. A laser generator 304 is fixedly connected to one side of the inner cavity of the inner ring 303. A laser receiver 305 is fixedly connected to the other side of the inner cavity of the inner ring 303. A drive motor is fixedly connected to one side of the fixed ring 302. A drive gear 306 is fixedly connected to the output shaft of the drive motor. A drive tooth that meshes with the tooth pattern of the drive gear 306 is opened on the outer surface of the inner ring 303.

[0023] Power on the entire laser cutting machine, including the laser cutting assembly 3, rotary motor 301, and drive motor. Based on the material, thickness, and cutting requirements of the steel body 5, set the corresponding cutting parameters on the control panel, such as laser power and cutting speed. Upon receiving the start signal, the laser generator 304 begins emitting a laser beam. The laser beam passes through the channel inside the inner ring 303 and is focused on the cutting surface of the steel body 5. The rotary motor 301 starts, causing the fixed ring 302 and its internal inner ring 303, laser generator 304, and laser receiver 305 to rotate together. According to the preset cutting path and angle, adjust the speed and direction of the rotary motor 301 via the control panel to change the direction and angle of the laser beam. The drive motor then starts. The drive gear 306 on its output shaft meshes with the drive teeth on the outer surface of the inner ring 303. The rotation of the drive gear 306 drives the inner ring 303 and its internal laser generator 304 and laser receiver 305 to make minute angle adjustments to achieve finer cutting. Under the irradiation of the laser beam, the cutting surface of the steel body 5 begins to melt and be blown away, forming a cutting gap. At the same time, the laser receiver 305 monitors the intensity and position of the laser beam in real time to ensure the stability and accuracy of the cutting process. When the steel body 5 is cut according to the preset path and shape, the laser beam stops emitting, the rotary motor 301 and the drive motor also stop working, the power of the laser cutting machine is turned off, and after the equipment cools down, the cut steel body 5 is taken out.

[0024] In this embodiment, guide limiting components 4 are provided on both sides of the top of the base 1. Each guide limiting component 4 includes a connecting frame 401 fixedly connected to the base 1. A limiting frame 402 is provided on the top of the connecting frame 401. Two symmetrically arranged sliding plates 404 are slidably connected inside the limiting frame 402. Limiting rollers 406 are provided on the opposite surfaces of the two sliding plates 404. The two sets of limiting rollers 406 are respectively attached to the top and bottom of the steel body 5. Guide protrusions 403 are fixedly connected on both sides of the inner cavity of the limiting frame 402. The two sliding plates 404 are slidably connected to the outside of the guide protrusions 403. Each sliding plate 404 faces the limiting frame. One side of each 402 is fixedly connected to the inner wall of the limiting frame 402 by an "S"-shaped elastic element 405. Each limiting frame 402 has an arc-shaped guide 407 fixedly connected to the side facing the input end of the steel body 5. The guides 407 on each pair of guide limiting components 4 in the same direction are symmetrically distributed on the top and bottom of the steel body 5. Each guide 407 has a sliding column 408 with the same path shape fixedly connected inside. The sliding column 408 is slidably connected to the outside of the sliding frame 409. The sliding frame 409 is rotatably connected to the guide roller 4010 on the side facing the steel body 5. The sliding column 408 is sleeved with a reset spring.

[0025] When no steel body 5 enters, the two sliding plates 404 are held in a relative position inside the limiting frame 402 by the tension of the "S"-shaped elastic element 405. Simultaneously, the guide roller 4010 is held near the exit of the guide 407 by the return spring. When the steel body 5 begins to enter the cutting area, it first contacts the guide roller 4010. Because the guide roller 4010 can rotate, it reduces friction between the steel and the equipment, making it easier for the steel to enter. As the steel body 5 continues to enter, it pushes the guide roller 4010 and the sliding frame 409 along the sliding column 408 into the limiting frame 402. During this process, the return spring is compressed, storing energy. At the same time, the top and bottom of the steel body 5... The guide roller 4010 will contact the limiting roller 406, pushing the sliding plate 404 to slide along the guide protrusion 403 and compress the "S"-shaped elastic element 405. When the steel body 5 is completely inside the limiting frame 402, the limiting roller 406, under the elastic force of the "S"-shaped elastic element 405, will tightly adhere to the top and bottom of the steel, achieving stable limiting of the steel. At the same time, the guide roller 4010, under the action of the return spring, will maintain slight contact with the steel, ensuring the smooth movement of the steel during the cutting process. After the steel body 5 is cut, it will continue to move forward and leave the limiting frame 402. At this time, the sliding plate 404 and the guide roller 4010 will return to their initial positions under the action of their respective elastic elements, ready to welcome the entry of the next piece of steel.

[0026] With the adaptive adjustment of the sliding plate 404 and the guide roller 4010, the guide limiting assembly 4 can automatically adapt to steel of different widths and heights without manual adjustment, improving cutting efficiency. Stable limiting and guiding ensure smooth movement of the steel during the cutting process, reducing swaying and deviation, and improving cutting accuracy. The guide limiting assembly 4 has a simple structure, with tight and stable connections between components, making it easy to maintain and replace. At the same time, the setting of the "S"-shaped elastic element 405 and the return spring increases the durability and reliability of the equipment. No additional operators are required to manually adjust the limiting device, reducing labor intensity and improving ease of operation.

[0027] The working principle and usage process of this utility model are as follows: Firstly, when no steel body 5 enters, the two sliding plates 404 are held in a relative position inside the limiting frame 402 by the pulling force of the "S"-shaped elastic element 405. Simultaneously, the guide roller 4010 is held near the exit of the guide element 407 by the action of the return spring. When the steel body 5 begins to enter the cutting area, it first contacts the guide roller 4010. Because the guide roller 4010 can rotate, it reduces friction between the steel and the equipment, making it easier for the steel to enter. As the steel body 5 continues to enter, it pushes the guide roller 4010 and the sliding frame 409 along the sliding column 408 into the limiting frame 402. During this process, the return spring is... Compression stores energy. Simultaneously, the top and bottom of the steel body 5 contact the limiting roller 406, pushing the sliding plate 404 to slide along the guide protrusion 403 and compressing the "S"-shaped elastic element 405. When the steel body 5 is fully inside the limiting frame 402, the limiting roller 406, under the elastic force of the "S"-shaped elastic element 405, tightly adheres to the top and bottom of the steel, achieving stable limiting of the steel. At the same time, the guide roller 4010, under the action of the return spring, maintains slight contact with the steel, ensuring smooth movement of the steel during the cutting process. The power supply of the entire laser cutting machine is started, including the laser cutting assembly 3, rotary motor 301, and drive motor, etc. According to the material, thickness, and cutting requirements of the steel body 5, the control... The control panel is set with appropriate cutting parameters, such as laser power and cutting speed. After receiving the start signal, the laser generator 304 begins to emit a laser beam. The laser beam passes through the channel inside the inner ring 303 and is focused on the cutting surface of the steel body 5. The rotary motor 301 starts, driving the fixed ring 302 and its internal inner ring 303, laser generator 304, and laser receiver 305 to rotate together. According to the preset cutting path and angle, the speed and direction of the rotary motor 301 are adjusted through the control panel, thereby changing the irradiation direction and angle of the laser beam. The drive motor starts, and the drive gear 306 on its output shaft meshes with the drive teeth on the outer surface of the inner ring 303. Through the rotation of the drive gear 306, the inner ring 303 and its internal components are driven to rotate. The laser generator 304 and laser receiver 305 are adjusted at minute angles to achieve finer cutting. Under the irradiation of the laser beam, the cutting surface of the steel body 5 begins to melt and be blown away, forming a cutting gap. At the same time, the laser receiver 305 monitors the intensity and position of the laser beam in real time to ensure the stability and accuracy of the cutting process. When the steel body 5 completes the cutting according to the preset path and shape, the laser beam stops emitting, and the rotary motor 301 and drive motor also stop working. After the steel body 5 completes the cutting, it will continue to move forward and leave the limiting frame 402. At this time, the sliding plate 404 and the guide roller 4010 will return to their initial positions under the action of their respective elastic elements, ready to welcome the next piece of steel.
