Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically a laser cutting device suitable for corrosion-resistant color-coated steel sheets. Background Technology

[0002] Corrosion-resistant color-coated steel sheets, as a high-performance metal material that combines aesthetics and protection, are made by precisely pre-coating a corrosion-resistant polymer coating such as polyester, silicon-modified polyester, or fluorocarbon onto a galvanized or aluminized zinc steel sheet substrate, followed by a rigorous baking and curing process. Thanks to its excellent corrosion resistance, this material has demonstrated wide and significant application value in various industries, including building exterior walls, roof panels, household appliance housings, and automotive and rail transportation, effectively extending product lifespan and improving overall quality.

[0003] In the processing of corrosion-resistant color-coated steel sheets, cutting is one of the key steps to achieve diversified applications. Considering the high hardness of the surface coating and the tight adhesion between it and the metal substrate, selecting appropriate cutting equipment is crucial to ensure processing accuracy and preserve the original protective properties of the color-coated steel sheet to the greatest extent. Currently, the mainstream cutting equipment is the laser cutting machine, which uses a high-energy focused laser beam to achieve precise melting or vaporization of the material. It not only has extremely high cutting accuracy and a small heat-affected zone, but can also smoothly cut complex shapes and minimize damage to the color coating. This ensures that the dimensional accuracy, structural integrity, and excellent corrosion resistance of the final product are fully utilized, thus forming a solid foundation for high-quality and aesthetically pleasing products.

[0004] Corrosion-resistant color-coated steel sheets require different widths for cutting during various applications. However, existing laser cutting equipment has a fixed structure and can only adjust the cutting width by moving the sheet material. Furthermore, existing laser cutting equipment cannot perform multiple cutting operations simultaneously, thus reducing processing efficiency. In addition, existing laser cutting equipment cannot easily and quickly replace the laser cutting head, resulting in performance deficiencies. Therefore, improvements are needed to address these issues. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device suitable for corrosion-resistant color-coated steel sheets, comprising an n-shaped plate frame, wherein a horizontal through groove is formed in the upper part of the n-shaped plate frame, and a vertical through groove communicating with the horizontal through groove is formed in the bottom of the upper part of the n-shaped plate frame.

The main H-beam slider is positioned between the auxiliary H-beam sliders, between two adjacent auxiliary H-beam sliders, and between one of the auxiliary H-beam sliders. The distance between each auxiliary I-beam slider and one end of the vertical through slot is the same.

The several long adjustment rods are rotatably mounted on the top of several auxiliary I-beam sliders. One end of the connecting rod is rotatably connected to the top of the main I-beam slider, and the other end of the connecting rod is connected to one end of an adjacent long adjustment rod via a movable shaft. The ends of any two adjacent long adjustment rods are connected via a movable shaft, and the adjustment rod is connected to one end of the long adjustment rod closest to the motor via a movable shaft.

[0007] Preferably, an adjusting shaft is rotatably mounted at one end of the transverse groove, one end of an adjusting rod is fixedly connected to the middle of the adjusting shaft, a worm gear is fixedly mounted at the top of the adjusting shaft, and a worm gear meshing with the worm gear is connected to the output end of the motor.

[0008] Preferably, the mounting groove includes a slot, a sliding inner groove, and a buffer groove, with the sliding inner groove located between the slot and the buffer groove, and the slot located at the bottom of the sliding inner groove and the buffer groove located at the top of the sliding inner groove.

[0009] Preferably, the self-locking opening component includes a slider slidably installed inside the sliding inner groove, an isosceles trapezoidal pressure block fixedly installed at the bottom of the slider, metal elastic sheets fixedly installed on both sides of the isosceles trapezoidal pressure block, and hook blocks symmetrically fixedly installed at one end of the two metal elastic sheets.

[0010] Preferably, the plug-in block includes an extension block and an isosceles trapezoidal extrusion block. The isosceles trapezoidal extrusion block is fixedly installed on the top of the extension block, which is installed on the top of the laser cutting head. The isosceles trapezoidal extrusion block is located inside the sliding inner groove and is clamped by two hook blocks. A spring layer is fixedly installed between the top of the slider and the top of the buffer groove.

[0011] Preferably, an mounting plate is fixedly installed on one side of the top of the slider, a connecting shaft is rotatably installed on one side of the mounting plate, a rotating plate is fixedly installed on one end of the connecting shaft, a torsion spring is sleeved on the surface of the connecting shaft, the two ends of the torsion spring are fixedly connected to the rotating plate and the mounting plate respectively, a limit rod is fixedly installed on one end of one side of the rotating plate, and a limit block for limiting and fixing the limit rod is fixedly installed in the middle of one side of the buffer groove.

[0012] Preferably, the limiting block has a pressing inclined surface and a removing inclined surface, the pressing inclined surface is located above the connecting shaft, and the top of the limiting block has a fixing groove, and the limiting rod is movably engaged inside the fixing groove.

[0013] Preferably, a stop block located directly above the limiting block is fixedly installed on the top of one side of the buffer groove. A sliding inclined surface is provided at one end of the bottom of the stop block, an extending groove is provided in the middle of the bottom of the stop block, and a reset inclined surface is provided at the other end of the bottom of the stop block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) This laser cutting device has a multi-station cutting and equal spacing adjustment structure and a laser cutting head disassembly and assembly structure. The multi-station cutting and equal spacing adjustment structure can cut multiple plates at the same time and can simultaneously adjust the equal spacing of multiple laser cutting heads, thereby effectively improving the cutting efficiency. The laser cutting head disassembly and assembly structure effectively improves the convenience and speed of laser cutting head replacement and disassembly, thereby effectively improving the performance of the laser cutting device.

[0016] (2) By starting the motor, the worm gear is rotated. The rotation of the worm gear will drive the worm wheel to rotate counterclockwise. The counterclockwise rotation of the adjustment shaft will drive the adjustment rod to rotate. The rotation of the adjustment rod will push the adjacent long adjustment rod to move and rotate. The movement of the long adjustment rod will drive the auxiliary I-beam slider connected to it to move. At the same time, the rotation of the long adjustment rod will drive the other long adjustment rod connected to it to rotate. Similarly, the other long adjustment rod will move and rotate synchronously. Similarly, other long adjustment rods and connecting rods will also move and rotate synchronously, so that several auxiliary I-beam sliders and the main I-beam slider can be adjusted at equal intervals synchronously.

[0017] (3) When installing the laser cutting head, position the isosceles trapezoidal extrusion block directly below the slot, then move the laser cutting head upwards, causing the laser cutting head to move the extension block and the isosceles trapezoidal extrusion block upwards, so that the extension block and the isosceles trapezoidal extrusion block are inserted into the slot and squeeze the isosceles trapezoidal pressure block. The isosceles trapezoidal pressure block drives the two hook blocks to move through the two metal elastic sheets, so that the two hook blocks move into the slot and are squeezed by the slot to lock the isosceles trapezoidal extrusion block; while the two hook blocks are squeezed and rotated, which will cause the two metal elastic sheets to bend and compress, and the movement of the isosceles trapezoidal pressure block will cause the slider to slide inside the sliding inner groove.

[0018] When the slider slides inside the sliding groove, it compresses the spring layer. At the same time, the movement of the slider will drive the mounting plate, connecting shaft, rotating plate and limit rod to move. The movement of the limit rod will contact the extrusion inclined surface and be squeezed and oscillated. The movement and oscillation of the limit rod will drive the rotating plate and connecting shaft to rotate and tighten the torsion spring.

[0019] When the limiting rod moves down between the limiting block and the stop block, the elastic restoring force of the torsion spring and the sliding inclined plane cause the connecting shaft and the rotating plate to rotate and reset, thus locking the limiting rod inside the fixed groove. At this time, the elastic restoring force of the spring layer will squeeze the slider, causing the slider to pull the limiting rod tight through the mounting plate, connecting shaft and rotating plate, making the limiting rod firmly locked inside the fixed groove. Therefore, the isosceles trapezoidal extrusion block can be stably and firmly installed inside the sliding inner groove through the two hook blocks, thus enabling the laser cutting head to be stably installed vertically.

[0020] When the laser cutting head needs to be disassembled, continue moving the laser cutting head upwards, causing the isosceles trapezoidal extrusion block to continue pushing the isosceles trapezoidal pressure block upwards. The movement of the isosceles trapezoidal pressure block will drive the slider, mounting plate, connecting shaft, rotating plate, and limit lever to move, causing the limit lever to move from inside the fixed groove to extend into the groove. At this point, the elastic restoring force of the torsion spring will move the limit lever to the reset slope. Then, move the laser cutting head downwards. Simultaneously, the elastic restoring force of the spring layer will cause the laser cutting head to move downwards through the isosceles trapezoidal extrusion block, driving the two hook blocks, the isosceles trapezoidal pressure block, the slider, mounting plate, connecting shaft, rotating plate, and limit lever. This allows the isosceles trapezoidal extrusion block to withdraw from the slot and sliding inner groove, completing the disassembly of the laser cutting head. At the same time, the two hook blocks will also move out of the slot and unfold and reset through the elastic restoring force of the two metal elastic sheets. The limit lever will also reset and move to below the extrusion slope.

[0021] (4) The multi-station cutting and equal spacing adjustment structure and the laser cutting head disassembly and assembly structure are simple in design, convenient and easy to use, and the cutting, adjustment and disassembly operations are stable and reliable. Its practicality can meet the use requirements of laser cutting of corrosion-resistant color-coated plates. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1, by Figures 1 to 8 The present invention includes an n-shaped plate frame 1, which is mounted on a placement platform. A corrosion-resistant color-coated plate is placed on top of the placement platform and inside the n-shaped plate frame 1. A ball bearing is installed on the top of the placement platform to facilitate movement of the corrosion-resistant color-coated plate. The placement platform and the ball bearing are not shown in the accompanying drawings. A horizontal through groove 2 is formed in the upper part of the n-shaped plate frame 1, and a vertical through groove 3 communicating with the horizontal through groove 2 is formed at the bottom of the upper part of the n-shaped plate frame 1. A main I-beam is installed between the interior of the horizontal through groove 2 and the vertical through groove 3. The main I-beam slider 4 and several secondary I-beam sliders 5 are installed at equal intervals between the interior of the transverse through groove 2 and the vertical through groove 3. The distances between the main I-beam slider 4 and the secondary I-beam sliders 5, between two adjacent secondary I-beam sliders 5, and between one of the secondary I-beam sliders 5 and one end of the vertical through groove 3 are all the same. An equally spaced adjustment frame 6 is installed at one end of the transverse through groove 2, between the main I-beam slider 4 and the several secondary I-beam sliders 5, and a motor 7 for adjusting the equally spaced adjustment frame 6 is installed at one end of the transverse through groove 2.

[0035] The bottom of the main I-beam slider 4 and several auxiliary I-beam sliders 5 are all equipped with mounting blocks 8. The bottom of the mounting block 8 is provided with a mounting groove 9. A self-locking opening component 10 is installed inside the mounting groove 9, and a plug-in block 11 is installed at the bottom of the mounting groove 9 through the self-locking opening component 10. A laser cutting head 12 is installed at the bottom of the plug-in block 11.

[0036] This laser cutting device features a multi-station cutting and equal-space adjustment structure, as well as a laser cutting head disassembly and assembly structure. The multi-station cutting and equal-space adjustment structure can cut multiple plates simultaneously and can synchronously adjust the equal spacing of multiple laser cutting heads, thereby effectively improving cutting efficiency. The convenient laser cutting head disassembly and assembly structure effectively improves the convenience and speed of laser cutting head replacement and disassembly, thus effectively improving the performance of the laser cutting device.

[0037] Meanwhile, the multi-station cutting and equal-spacing adjustment structure and the laser cutting head disassembly and assembly structure are simple in design, convenient and easy to use, and the cutting, adjustment and disassembly operations are stable and reliable. Its practicality can meet the application requirements of laser cutting of corrosion-resistant color-coated steel sheets.

[0038] In Embodiment 2, based on Embodiment 1, the equidistant adjustment frame 6 includes several long adjustment rods 13, connecting rods 14, and adjustment rods 15. The several long adjustment rods 13 are rotatably mounted on the top of several auxiliary I-beam sliders 5. One end of the connecting rod 14 is rotatably connected to the top of the main I-beam slider 4, and the other end of the connecting rod 14 is connected to one end of an adjacent long adjustment rod 13 via a movable shaft. The ends of any two adjacent long adjustment rods 13 are connected via a movable shaft. The adjustment rod 15 is connected to one end of the long adjustment rod 13 near the motor 7 via a movable shaft.

[0039] An adjusting shaft 16 is rotatably mounted at one end of the transverse through groove 2. One end of the adjusting rod 15 is fixedly connected to the middle of the adjusting shaft 16. A worm gear 17 is fixedly mounted on the top of the adjusting shaft 16. The output end of the motor 7 is connected to a worm 18 that meshes with the worm gear 17, thereby enabling effective equal-interval adjustment.

[0040] Specifically, by starting the motor 7, the worm gear 18 is rotated. The rotation of the worm gear 18 drives the worm wheel 17 to rotate the adjusting shaft 16 counterclockwise. The counterclockwise rotation of the adjusting shaft 16 drives the adjusting rod 15 to rotate. The rotation of the adjusting rod 15 pushes the adjacent long adjusting rod 13 to move and rotate. The movement of the long adjusting rod 13 drives the connected auxiliary I-beam slider 5 to move. At the same time, the rotation of the long adjusting rod 13 drives another connected long adjusting rod 13 to rotate. Similarly, the other long adjusting rods 13 and the connecting rod 14 will also move and rotate synchronously, so that several auxiliary I-beam sliders 5 and the main I-beam slider 4 can be adjusted synchronously at equal intervals.

[0041] At this time, the distances between the main I-beam slider 4 and the secondary I-beam slider 5, between two adjacent secondary I-beam sliders 5, and between one of the secondary I-beam sliders 5 and one end of the vertical through groove 3 are all the same; then, the corrosion-resistant color-coated plate is placed on the top of the placement table, and the corrosion-resistant color-coated plate is moved by rolling, so that one side of the corrosion-resistant color-coated plate is connected to one side of the inside of the n-shaped plate frame 1 and aligned with one end of the vertical through groove 3; then, all the laser cutting heads 12 are started and the corrosion-resistant color-coated plate is moved, so that the corrosion-resistant color-coated plate can be cut simultaneously in multiple pieces.

[0042] In Example 3, based on Example 1, the mounting groove 9 includes a slot 19, a sliding inner groove 20, and a buffer groove 21. The sliding inner groove 20 is located between the slot 19 and the buffer groove 21, with the slot 19 located at the bottom of the sliding inner groove 20 and the buffer groove 21 located at the top of the sliding inner groove 20. The self-locking opening component 10 includes a slider 22 slidably installed inside the sliding inner groove 20. An isosceles trapezoidal pressure block 23 is fixedly installed at the bottom of the slider 22. Metal elastic sheets 24 are fixedly installed on both sides of the isosceles trapezoidal pressure block 23, and hook blocks 25 are symmetrically fixedly installed at one end of the two metal elastic sheets 24.

[0043] The plug-in block 11 includes an extension block 26 and an isosceles trapezoidal extrusion block 27. The isosceles trapezoidal extrusion block 27 is fixedly installed on the top of the extension block 26. The extension block 26 is installed on the top of the laser cutting head 12. The isosceles trapezoidal extrusion block 27 is located inside the sliding inner groove 20 and is clamped by two hook blocks 25.

[0044] Specifically, when installing the laser cutting head 12, the isosceles trapezoidal extrusion block 27 is positioned directly below the slot 19. Then, the laser cutting head 12 is moved upward, causing the extension block 26 and the isosceles trapezoidal extrusion block 27 to move upward, so that the extension block 26 and the isosceles trapezoidal extrusion block 27 are inserted into the slot 19 and extruded and moved by the isosceles trapezoidal pressure block 23. The isosceles trapezoidal pressure block 23 moves by two metal elastic sheets 24, causing two hook blocks 25 to move into the slot 19 and be squeezed by the slot 19 to lock the isosceles trapezoidal extrusion block 27. The two hook blocks 25 are squeezed and rotated, which causes the two metal elastic sheets 24 to bend and compress. The movement of the isosceles trapezoidal pressure block 23 causes the slider 22 to slide inside the sliding inner groove 20.

[0045] In Example 4, based on Example 3, a spring layer 28 is fixedly installed between the top of the slider 22 and the top of the buffer groove 21. When the slider 22 slides inside the sliding inner groove 20, it will compress the spring layer 28. A mounting plate 29 is fixedly installed on one side of the top of the slider 22. A connecting shaft 30 is rotatably installed on one side of the mounting plate 29. A rotating plate 31 is fixedly installed on one end of the connecting shaft 30. A torsion spring 32 is sleeved on the surface of the connecting shaft 30. The two ends of the torsion spring 32 are fixedly connected to the rotating plate 31 and the mounting plate 29, respectively. A limit rod 33 is fixedly installed on one end of one side of the rotating plate 31. A limit block 34 is fixedly installed in the middle of one side of the buffer groove 21 to limit and fix the limit rod 33.

[0046] The limiting block 34 has a pressing slope 35 and a removing slope 37. The pressing slope 35 is located above the connecting shaft 30. The top of the limiting block 34 has a fixing groove 36, and the limiting rod 33 is movably engaged inside the fixing groove 36. A stop block 38 located directly above the limiting block 34 is fixedly installed on the top of one side of the buffer groove 21. A sliding slope 39 is provided at one end of the bottom of the stop block 38, an extending groove 40 is provided in the middle of the bottom of the stop block 38, and a reset slope 41 is provided at the other end of the bottom of the stop block 38, so that the installation limiting fixation and disassembly reset separation operation can be effectively performed.

[0047] Specifically, when the slider 22 slides inside the sliding groove 20, it compresses the spring layer 28. At the same time, the movement of the slider 22 will drive the mounting plate 29, the connecting shaft 30, the rotating plate 31 and the limiting rod 33 to move. The movement of the limiting rod 33 will contact the extrusion inclined surface 35 and be squeezed and oscillated. The movement and oscillation of the limiting rod 33 will drive the rotating plate 31 and the connecting shaft 30 to rotate and tighten the torsion spring 32.

[0048] When the limiting rod 33 moves down between the limiting block 34 and the stop block 38, the elastic restoring force of the torsion spring 32 and the sliding inclined plane 39 will cause the connecting shaft 30 and the rotating plate 31 to rotate and reset, thereby locking the limiting rod 33 inside the fixed groove 36. At this time, the elastic restoring force of the spring layer 28 will squeeze the slider 22, thereby causing the slider 22 to pull the limiting rod 33 through the mounting plate 29, the connecting shaft 30 and the rotating plate 31, so that the limiting rod 33 is firmly locked inside the fixed groove 36. Therefore, the isosceles trapezoidal extrusion block 27 can be stably and firmly installed inside the sliding inner groove 20 through the two hook blocks 25, thereby enabling the laser cutting head 12 to be stably installed vertically.

[0049] When the laser cutting head 12 needs to be disassembled, continue to move the laser cutting head 12 upward, so that the isosceles trapezoidal extrusion block 27 continues to push the isosceles trapezoidal pressure block 23 upward. The movement of the isosceles trapezoidal pressure block 23 will drive the slider 22, mounting plate 29, connecting shaft 30, rotating plate 31 and limiting rod 33 to move, so that the limiting rod 33 moves from the inside of the fixing groove 36 to the inside of the groove 40. At this time, the elastic restoring force of the torsion spring 32 will make the limiting rod 33 move to the reset slope 41; then the laser cutting head 12 is moved downward, and at the same time the elastic restoring force of the spring layer 28 will move the limiting rod 33 to the reset slope 41. The laser cutting head 12 is disassembled by moving the two hook blocks 25, the isosceles trapezoidal pressure block 23, the slider 22, the mounting plate 29, the connecting shaft 30, the rotating plate 31, and the limiting rod 33 downwards via the isosceles trapezoidal extrusion block 27. This allows the isosceles trapezoidal extrusion block 27 to be withdrawn from the slot 19 and the sliding inner groove 20. At the same time, the two hook blocks 25 will also move out of the slot 19 and be unfolded and reset by the elastic restoring force of the two metal elastic sheets 24. The limiting rod 33 will also be reset and moved below the extrusion slope 35.
