The cleaning device is arranged to keep the cutting table clean, and the collecting device is arranged to facilitate the subsequent resource recovery and reuse to save costs.

[0007] According to the above technical solution, the contacting surfaces of the push rod 1 and the inclined plane block 1 are both set as inclined planes, the support column is in contact with the workbench, and a collecting groove is provided on the top of the workbench. The inclined plane is provided to ensure that the push rod 1 can smoothly push the inclined plane block 1 when moving, and the collecting groove is provided to ensure that the welding slag can be cleaned.

[0008] According to the above technical scheme, the cleaning device includes an elastic telescopic rod 2, a scraper rod, a sloped block 2, an elastic telescopic rod 3, a pressure plate and a pressure rod.

[0014] The present invention provides an adjustable laser cutting machine for metal processing, which has the following beneficial effects: (1) This invention prevents the plate from shifting due to thermal deformation or vibration during the cutting process by moving the clamp to contact and clamp the metal, thereby ensuring a more accurate cutting process and avoiding cutting errors caused by changes in the workpiece position. At the same time, it ensures that there is no risk of the workpiece loosening or slipping during the cutting process, thus avoiding safety hazards that may be caused by the unstable position of the workpiece.

[0015] (2) This invention can separate the metal workpiece from the cutting table by moving the lifting plate to move the metal upward, thereby creating more space and ensuring smooth airflow in the cutting area, which is conducive to the rapid discharge of slag and prevents the slag from re-contacting the cutting surface, resulting in an uneven surface or incomplete cutting.

[0016] (3) This invention uses a scraper to clean the welding slag that falls on the workbench during welding, thereby avoiding problems caused by interference from welding slag in subsequent steps, reducing the difficulty and cost of secondary processing, and improving overall processing efficiency. At the same time, it keeps the cutting table clean, avoids the accumulation of welding slag that affects the cutting process, and reduces equipment failures or other safety hazards caused by welding slag.

[0017] (4) The invention, by moving the contact plate to contact the roller, cleans the welding slag that may remain on the roller when the roller rotates, thereby preventing the roller surface from being dirty or blocked, and the metal plate from being offset or stuck, resulting in uneven cutting or reduced precision, thereby extending the service life of the roller and other related parts and reducing the cost of equipment maintenance and replacement.

[0018] (5) The invention, by dumping the collected welding slag at a designated location for centralized treatment, is conducive to the subsequent resource recovery and reuse to save costs, prevent welding slag from scattering into the work area, reduce safety hazards, help reduce environmental pollution, keep the workshop clean, and at the same time help extend the service life of equipment and reduce maintenance costs. By moving the clamping rod to contact the clamping block and restricting the collection box, the collection box is prevented from being displaced due to vibration or improper operation, resulting in welding slag overflow or incomplete collection, ensuring that welding slag and metal chips can be safely collected, while avoiding the need for frequent adjustments due to its instability, thereby improving work efficiency and production continuity.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 7 , one embodiment of the present invention is: an adjustable laser cutting machine for metal processing, comprising a workbench 1, a support leg 2 is fixedly installed at the bottom of the workbench 1, a motor 3 is fixedly installed at the front of the workbench 1, a threaded rod 4 is fixedly installed at the output end of the motor 3, a support column 5 is slidably installed on the circumference of the threaded rod 4, a cutting device 6 is slidably installed between the two support columns 5, and a clamping device is arranged on the top of the workbench 1; Among them, the clamping device includes a roller 7, an electric push rod 8, a clamping plate 9, a push rod 10, an elastic telescopic rod 11, a lifting plate 12 and a bevel block 13. The roller 7 is rotatably installed inside the workbench 1, the electric push rod 8 is fixedly installed inside the workbench 1, the clamping plate 9 is fixedly installed at the output end of the electric push rod 8, the push rod 10 is fixedly installed at the bottom of the clamping plate 9, the elastic telescopic rod 11 is fixedly installed on the top of the workbench 1, the lifting plate 12 is fixedly installed at the movable end of the elastic telescopic rod 11, and the bevel block 13 is fixedly installed at the bottom of the lifting plate 12. The clamping plate 9 moves to contact and clamp the metal to prevent the plate from being offset due to thermal deformation or vibration during the cutting process, thereby ensuring that the cutting process is more accurate and avoiding cutting errors caused by changes in the workpiece position. At the same time, it ensures that there is no risk of loosening or slipping of the workpiece during the cutting process, thereby avoiding safety hazards caused by unstable workpiece position.

[0023] The sides of the push rod 10 and the inclined block 13 that contact each other are both set as inclined surfaces, the support column 5 is in contact with the workbench 1, and a collecting groove is provided on the top of the workbench 1. The inclined surface is provided to ensure that the push rod 10 can smoothly push the inclined block 13 when moving, and the collection groove is provided to ensure that the welding slag can be cleaned.

[0024] When this embodiment is working: first, the staff checks the working state of the cutting machine before working. After confirming that it is correct, the staff pushes the metal to be cut to the middle position of the workbench 1 through the transmission of the roller 7. When the metal moves to the specified position, the motor 3 is started to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the support column 5 to move. The movement of the support column 5 drives the cutting device 6 to start moving. After the cutting device 6 moves to the specified position, the staff starts the cutting device 6 to cut the metal. Before starting cutting, the staff starts the electric push rod 8 to push the clamping plate 9 to start moving. The clamping plate 9 moves to contact and clamp the metal to prevent the plate from being deformed or deformed due to heat during the cutting process. The deviation caused by vibration ensures that the cutting process is more precise and avoids cutting errors caused by changes in the position of the workpiece. At the same time, it ensures that there is no risk of the workpiece loosening or slipping during the cutting process, avoiding the safety hazards caused by the unstable position of the workpiece. When the clamp 9 moves, it drives the push rod 10 to start moving. The push rod 10 moves to contact and push the inclined block 13 to start moving upward. The movement of the inclined block 13 drives the lifting plate 12 to start moving upward. The lifting plate 12 moves the metal upward, which can separate the metal workpiece from the cutting table and create more space. This ensures smooth airflow in the cutting area, which is conducive to the rapid discharge of slag and avoids the slag from re-contacting the cutting surface, resulting in an uneven surface or incomplete cutting.
