Technical Field

[0001] This utility model relates to the field of fire door production technology, specifically a laser cutting machine for steel fire door production lines. Background Technology

[0002] Fire doors are fire-resistant partitions with a certain degree of fire resistance installed in fire-resistant compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. They can stop the spread of fire for a certain period of time and ensure the evacuation of personnel. In the production line of fire doors, laser cutting machines are used to cut the steel plates used to produce fire doors. The specific model of the laser cutting machine is MF-3015C.

[0003] In response, Chinese patent application number CN202020729500.X discloses a cutting machine for manufacturing fire doors, comprising a cutting machine tool, a moving arm, a laser cutter, and a control display. The cutting machine tool has a support platform on top for placing steel plates. The support platform includes multiple support plates, with gaps between adjacent support plates. An L-shaped fixing plate for limiting the position of the steel plate is provided on one side of the support platform along its length. The cutting machine tool has a cavity containing a clamping member for holding the steel plate and a driving member for driving the clamping member to reciprocate along a direction parallel to the length of the moving arm. The top of the clamping member is located within the gap. This invention effectively and stably fixes the steel plate on the support platform.

[0004] The device uses movable clamps on the top surface of the support platform to fix the steel plate on the support platform. However, the clamps make the top surface of the support platform uneven and have protrusions. When the steel plate is placed on the support platform, the clamps will obstruct the placement of the steel plate. The steel plate needs to be moved to avoid the clamps in order to place the steel plate between the clamps and the L-shaped fixing plate. This is time-consuming and labor-intensive, affects the processing efficiency of the steel plate, and makes the use of the device quite limited.

[0005] Therefore, in order to solve the above problems, a special laser cutting machine for steel fire door production lines is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a laser cutting machine specifically for steel fire door production lines, in order to solve the problem mentioned in the background art where the prior art uses movable clamping parts on the top surface of the support platform to fix the steel plate on the support platform. However, the clamping parts make the top surface of the support platform uneven and have protrusions. When the steel plate is placed on the support platform, the clamping parts will obstruct the placement of the steel plate. It is necessary to move the steel plate to avoid the clamping parts in order to place the steel plate between the clamping parts and the L-shaped fixing plate. This is time-consuming and labor-intensive, affects the processing efficiency of the steel plate, and makes the use of the device quite limited.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a special laser cutting machine for steel fire door production line, comprising: a support platform, a controller installed on the right side of the support platform, a laser cutter installed on the support platform, material placed on the top surface of the support platform, and an L-shaped positioning plate provided on the top surface of the support platform; A positioning structure is installed on the L-shaped positioning plate. The positioning structure includes a guide rail, which is fixedly installed on the top surface of the L-shaped positioning plate. A threaded rod is movably installed on the top surface of the L-shaped positioning plate via a bearing. A motor is installed on one side of the guide rail. A moving block is movably installed on the top surface of the L-shaped positioning plate. A guide groove is opened on the bottom surface of the moving block. An abutment plate is movably installed on the side wall of the moving block via a hinge. A rubber protective pad is adhered to the surface of the abutment plate.

[0008] Preferably, the material is located inside the L-shaped positioning plate, and the material is attached to the inner wall of the L-shaped positioning plate.

[0009] Preferably, the positioning structure is provided in two sets, and the two sets of positioning structures are respectively located on the two right-angled surfaces at the top of the L-shaped positioning plate.

[0010] Preferably, the threaded rod passes through the movable block and is threadedly connected to the movable block.

[0011] Preferably, the guide rail is slidably mounted on the inner side of the guide groove, the motor is fixedly mounted on the top surface of the L-shaped positioning plate, and the output end of the motor is fixedly connected to the threaded rod.

[0012] Preferably, the abutment plate is located inside the L-shaped positioning plate, and there is a gap between the bottom surface of the abutment plate and the top surface of the support platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The abutment plate of this utility model is movably installed on the moving block by a hinge. Before placing the steel plate, the abutment plate can be flipped to the upper side of the moving block to reduce the space occupied by the abutment plate and the moving block on the top surface of the support platform. Moreover, the moving block is located on the top surface of the L-shaped positioning plate, which further reduces the space occupied by the positioning structure on the top surface of the support platform, so that there is enough space on the top surface of the support platform to place and adjust the steel plate, thus ensuring the practicality of the device.

[0014] This utility model features a positioning structure. Pulling the abutment plate causes it to flip on the moving block via a hinge, allowing it to be moved away from the inside of the L-shaped positioning plate. The abutment plate can also rotate to the top of the moving block, ensuring that only the L-shaped positioning plate occupies a portion of the top surface of the support platform. When materials are placed inside the L-shaped positioning plate, they are not obstructed by the abutment plate, allowing workers to easily place or move materials, ensuring convenient material placement. Starting the motor rotates the threaded rod, which is threadedly connected to the moving block, which is guided by a guide groove. The sliding plate is mounted on the outside of the guide rail. When the threaded rod rotates, it drives the moving block to slide on the guide rail. The position of the moving block on the L-shaped positioning plate can be adjusted so that the abutment plate can be moved to the outside of the material. Then, the abutment plate is pulled down from the moving block. When the motor is started again, the moving block drives the abutment plate closer to the material. The abutment plate abuts against the material, which can fix the material on the inside of the L-shaped positioning plate. A rubber protective pad is attached to the abutment plate between the abutment plate and the material, which can effectively prevent the abutment plate from abrading the material and improve the practicality of the device.

A positioning structure 2 is installed on the L-shaped positioning plate 21. The positioning structure 2 includes a guide rail 22, which is fixedly installed on the top surface of the L-shaped positioning plate 21. A threaded rod 23 is movably installed on the top surface of the L-shaped positioning plate 21 via a bearing. A motor 24 is installed on one side of the guide rail 22. A moving block 25 is movably installed on the top surface of the L-shaped positioning plate 21. A guide groove 26 is opened on the bottom surface of the moving block 25. An abutment plate 28 is movably installed on the side wall of the moving block 25 via a hinge 27. The surface of the abutment plate 28 is adhered to... With a rubber protective pad 29 attached, the abutment plate 28 is movably mounted on the movable block 25 via a hinge 27. Before placing the steel plate, the abutment plate 28 can be flipped to the upper side of the movable block 25 to reduce the space occupied by the abutment plate 28 and the movable block 25 on the top surface of the support platform 1. Furthermore, the movable block 25 is located on the top surface of the L-shaped positioning plate 21, further reducing the space occupied by the positioning structure 2 on the top surface of the support platform 1. This allows for ample space on the top surface of the support platform 1 to place and adjust the steel plate, ensuring the practicality of the device.

[0020] Furthermore, material 3 is located inside the L-shaped positioning plate 21, and material 3 is attached to the inner wall of the L-shaped positioning plate 21. The L-shaped positioning plate 21 provides a limit for the placement of material 3 on the top surface of the support platform 1.

[0021] Furthermore, the positioning structure 2 is provided in two sets, which are located on the two right-angled surfaces at the top of the L-shaped positioning plate 21. The two sets of positioning structures 2 can push the material 3 so that the outer wall of the material 3 fits against the inner wall of the L-shaped positioning plate 21, thereby limiting the position of the material 3.

[0022] Furthermore, the threaded rod 23 passes through the movable block 25 and is threadedly connected to the movable block 25. The rotation of the threaded rod 23 can drive the movable block 25 to move on the guide rail 22.

[0023] Furthermore, the guide rail 22 is slidably installed on the inner side of the guide groove 26, the motor 24 is fixedly installed on the top surface of the L-shaped positioning plate 21, the output end of the motor 24 is fixedly connected to the threaded rod 23, the guide groove 26 cooperates with the guide rail 22 to provide a limit for the movement of the moving block 25 on the L-shaped positioning plate 21, and the motor 24 provides power for the rotation of the threaded rod 23.

[0024] Furthermore, the abutment plate 28 is located inside the L-shaped positioning plate 21, and there is a gap between the bottom surface of the abutment plate 28 and the top surface of the support platform 1. The abutment plate 28 provides a pushing force for the material 3 to adhere to the inner wall of the L-shaped positioning plate 21.

[0025] Working principle: Before processing material 3, pull the abutment plate 28 so that the abutment plate 28 can be flipped on the moving block 25 through the hinge 27. The abutment plate 28 can be moved away from the inside of the L-shaped positioning plate 21 and rotated to the top of the moving block 25 so that only the L-shaped positioning plate 21 occupies part of the space on the top surface of the support platform 1. When material 3 is placed inside the L-shaped positioning plate 21, material 3 will not be blocked by the abutment plate 28. The staff can easily place material 3 inside the L-shaped positioning plate 21 or move material 3, ensuring the convenience of placing material 3. The motor 24 is started, driving the threaded rod 23 to rotate. The threaded rod 23 is threadedly connected to the moving block 25, and the moving block 25 is slidably mounted on the outside of the guide rail 22 through the guide groove 26. When the threaded rod 23 rotates, it drives the moving block 25 to slide on the guide rail 22. The position of the moving block 25 on the L-shaped positioning plate 21 can be adjusted so that the abutment plate 28 can be moved to the outside of the material 3 through the moving block 25. Then, the abutment plate 28 is pulled down from the moving block 25. The motor 24 is started again, and the moving block 25 drives the abutment plate 28 to approach the material 3. The abutment plate 28 abuts against the material 3, which can fix the material 3 on the inside of the L-shaped positioning plate 21. A rubber protective pad 29 is attached to the abutment plate 28. The rubber protective pad 29 is placed between the abutment plate 28 and the material 3, which can effectively prevent the abutment plate 28 from causing wear to the material 3 and improve the practicality of the device.
