[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 4 and Figure 9 As shown in the embodiment of the present invention, a high-efficiency laser cutting device for hardware includes an outer frame 1 and a fixing assembly. The fixing assembly includes a drive rod 2, a lifting seat 3, and rotating rollers 4. One end of the drive rod 2 is fixedly connected to the bottom of the inner wall of the outer frame 1. There are two rotating rollers 4, which are symmetrically arranged above the outer frame 1. The fixing assembly drives the lifting seat 3 to move upward through the drive rod 2. The lifting seat 3 moves the workpiece upward and automatically fixes the workpiece in conjunction with the rotating rollers 4. A laser cutting head 33 is arranged above the outer frame 1. The device is used for cutting tubular hardware. During operation, the metal workpiece to be cut is placed inside the device. The workpiece will slide down to the top of the lifting seat 3 under its own gravity. Then, under the action of the drive rod 2, the lifting seat 3 is moved upward. The lifting seat 3 pushes the workpiece upward. When the workpiece moves to the top of the outer frame 1, the rotating roller 4 will limit the workpiece at the top, thereby fixing the workpiece with the lifting seat 3, thus achieving the effect of automatic feeding. There is no need to manually reload after each cutting operation. After the workpiece is fixed, the laser cutting head 33 starts to work and cuts the workpiece.

[0036] like Figures 1 to 4As shown, a feeding box 5 is fixedly installed on the inner wall of one side of the outer frame 1. Channel plates 6 are symmetrically fixedly installed on the inner wall of the outer frame 1. One end of the feeding box 5 located inside the outer frame 1 is fixedly connected to one of the channel plates 6. A receiving plate 7 is fixedly installed on the end of the drive rod 2 away from the outer frame 1. A flipping assembly is fixedly installed on the top of the receiving plate 7. The receiving plate 7 is fixedly connected to the lifting seat 3 through the flipping assembly. A top positioning seat 8 is symmetrically fixedly installed on the top of the outer frame 1. A rotating shaft 9 is rotatably installed on the inner wall of the top positioning seat 8. The outer walls of the two rotating shafts 9 are rotatably connected to the inner walls of the two rotating rollers 4, respectively. During operation, the tubular hardware workpiece is placed from one end of the feeding box 5 into the inner side of the feeding box 5. The hardware workpiece will be subjected to its own gravity. The material slides down the feed box 5 onto the lifting seat 3. Then, the drive rod 2 is activated, extending to push the lifting seat 3 upward inside the channel plate 6. The lifting seat 3 then moves the metal workpiece upward. When the workpiece moves to the rotating roller 4, the rotating roller 4 limits the workpiece from the top, thus fixing the workpiece and achieving automatic feeding and fixing. The width of the inner side of the feed box 5 is consistent with the width between the upper parts of the two channel plates 6. This technical solution is suitable for processing tubular five-piece workpieces. At the same time, the maximum outer diameter of the tubular metal workpiece is equal to the width of the inner side of the feed box 5, and the minimum outer diameter of the tubular metal workpiece is greater than half the width of the inner side of the feed box 5 to avoid jamming.

[0037] like Figures 1 to 5As shown, the flipping assembly includes symmetrically arranged supports 10. A hinge seat 11 is fixedly installed between the tops of the two supports 10. The top of the hinge seat 11 is fixedly connected to the bottom of the lifting seat 3. Arc-shaped telescopic rods A12 and elastic elements A13 are fixedly installed on the outer walls of both supports 10. The ends of the arc-shaped telescopic rods A12 and elastic elements A13 away from the supports 10 are fixed to the bottom of the lifting seat 3. The two elastic elements A13 are respectively sleeved on the outer sides of the two arc-shaped telescopic rods A12. Support plates 14 are symmetrically fixedly installed on the inner wall of the receiving plate 7. The top of the support plate 14 abuts against the bottom of the lifting seat 3. An extrusion baffle 15 is fixedly installed on the outer wall of the channel plate 6 near the feed box 5. The side of the lifting seat 3 away from the arc-shaped telescopic rods A12 is located above the extrusion baffle 15. The support plate 14 is fixed to the bottom of the lifting seat 3 through the receiving plate 7. The support plate 14 supports the lifting seat 3 to prevent the lifting seat 3 from deflecting away from the arc-shaped telescopic rod A12 when the tubular hardware workpiece falls onto it. After the workpiece is cut, the drive rod 2 will retract to drive the lifting seat 3 to move down. During the downward movement, the lifting seat 3 will pass through the extrusion baffle 15, which will come into contact with one side of the lifting seat 3, thus extruding the lifting seat 3 and causing it to flip around the hinge seat 11. The elastic element A13 and the arc-shaped telescopic rod A12 will retract accordingly. When the lifting seat 3 flips, the side away from the extrusion baffle 15 will overlap with the discharge box 32. The workpiece on the lifting seat 3 will slide down from the tilted lifting seat 3 into the discharge box 32 under its own weight, thus achieving the effect of automatic discharge. There is no need for manual repeated removal of the workpiece, which improves work efficiency.

[0038] like Figures 1 to 9 As shown, a drive motor 16 is installed above the outer frame 1. A drive wheel 17 is fixedly mounted on the output shaft of the drive motor 16. A driven wheel 18 is fixedly mounted on one end of a rotating shaft 9. A transmission belt 19 is installed between the driven wheel 18 and the drive wheel 17. A support roller 20 is rotatably mounted on the inner wall of the lifting seat 3. When cutting the workpiece, after one cutting operation is completed, the drive motor 16 is started. The drive motor 16 drives the drive wheel 17 to rotate. The drive wheel 17 drives the driven wheel 18 to rotate through the transmission belt 19. When the driven wheel 18 rotates, it drives the rotating roller 4 to rotate through the rotating shaft 9. The workpiece is located between the rotating roller 4 and the support roller 20. The support roller 20 is capable of rotation. Therefore, when the rotating roller 4 rotates, it drives the workpiece to rotate. The angle of the workpiece can be adjusted by rotating the workpiece, so that multiple cutting operations can be performed on the surface of a workpiece, increasing the convenience of the device and improving work efficiency.

[0039] like Figures 1 to 7As shown, a bracket 21 is fixedly installed on the bottom of the inner wall of the outer frame 1. A support rod 22 is rotatably installed on the inner wall of the bracket 21. A gear roller 23 is rotatably installed on the outer wall of the support rod 22. A limiting seat 24 is fixedly installed on the bottom of the inner wall of the outer frame 1 and on one side of the bracket 21. Lifting baffles 25 are symmetrically slidably installed on the inner wall of the limiting seat 24. The teeth of both lifting baffles 25 mesh with the teeth of the gear roller 23. The feed box 5 and the channel plate 6 adjacent to it are slidably connected to the lifting baffles 25. When the lifting seat 3 is lifted, the receiving plate 7 will follow and lift. When the lifting seat 3 moves the workpiece upward for cutting... During operation, the receiving plate 7 will drive the support plate 14 to move upward, and the support plate 14 will block one end of the feed box 5, thereby preventing the workpieces located in the feed box 5 from sliding down to the inside of the channel plate 6 and jamming the device, causing a malfunction. When the lifting seat 3 moves downward to perform the discharge operation, the receiving plate 7 will drive the support plate 14 to move downward. When the support plate 14 moves downward, it will mesh with the gear roller 23, thereby causing the gear roller 23 to rotate. When the gear roller 23 rotates, it will mesh with the lifting baffle 25, which will block one end of the feed box 5, thereby preventing the workpieces located in the feed box 5 from being discharged during the discharge operation.

[0040] like Figures 1 to 10 As shown, rotating seats 26 are symmetrically fixedly installed on the top of the outer frame 1. A positioning shaft 27 is rotatably installed between the inner walls of the two rotating seats 26. A connecting plate 28 is symmetrically rotatably installed on the outer wall of the positioning shaft 27. An arc-shaped scraper 29 is fixedly installed between the outer walls of the two connecting plates 28. Several arc-shaped telescopic rods B30 and elastic elements B31 are fixedly installed between the arc-shaped scraper 29 and the outer frame 1. Several elastic elements B31 are respectively sleeved on the outside of several arc-shaped telescopic rods B30. When the workpiece to be cut is fixed, the workpiece will come into contact with the collection trough 45 under the action of the arc-shaped scraper 29. When the contact occurs, the connecting plate 28 will rotate around the positioning shaft 27 under the action of the contact force. At this time, the arc-shaped telescopic rods B30 and elastic elements B31 are in a contracted state. The collection trough 45 will come into contact with the surface of the tubular workpiece under the action of the reverse elastic force of the elastic element B31. To maintain a tight fit and prepare for subsequent cleaning, the workpiece rotates under the action of the drive motor 16 before cutting. When the workpiece rotates, the collection trough 45 cleans the surface of the workpiece, removing impurities adhering to the surface and improving the subsequent processing effect. Before adjusting the angle after each cutting operation, the drive motor 16 drives the workpiece to rotate back and forth. Since the collection trough 45 and the workpiece cutting position are both located between the two rotating rollers 4, the cutting position swings back and forth between the two rotating rollers 4 when the workpiece rotates back and forth. The collection trough 45 grinds the cutting position, removing any abnormal protrusions that may occur after laser cutting. This prevents the abnormal protrusions from interfering with the rotating rollers 4 or support rollers 20 when the workpiece is adjusted at the angle, avoiding deviations during angle adjustment and ensuring the processing accuracy of the device.

[0041] like Figures 1 to 10 As shown, a material collection trough 45 is provided on the side of the arc-shaped scraper 29 away from the arc-shaped telescopic rod B30. A snap-fit ​​block 44 is fixedly installed on the outer wall of the material collection trough 45. A snap-fit ​​groove is opened on the side of the arc-shaped scraper 29 away from the arc-shaped telescopic rod B30. The snap-fit ​​block 44 snaps into the inner wall of the snap-fit ​​groove. When cleaning the surface of the workpiece, the impurities being cleaned will gather in the inner side of the material collection trough 45 for collection, preventing the impurities after cleaning from remaining on the surface of the device and affecting the processing effect. The material collection trough 45 can be removed by the cooperation of the snap-fit ​​block 44 and the snap-fit ​​groove, so as to facilitate the processing of the collected impurities.

[0042] like Figures 1 to 3 As shown, a discharge box 32 is fixedly installed on the inner wall of the outer frame 1 on the side away from the feed box 5. The discharge box 32 is fixedly connected to the channel plate 6 away from the feed box 5. A discharge plate 41 is fixedly installed on the side of the discharge box 32 away from the channel plate 6. A feeding rack 42 is fixedly installed on the outer wall of the discharge plate 41. During discharge, the processed workpiece will slide down the discharge box 32 onto the discharge plate 41. After the workpiece reaches the discharge plate 41, it will continue to slide down the discharge plate 41. Finally, the workpiece will slide down to the inner side of the feeding rack 42 for collection, which is convenient for subsequent processing.

[0043] like Figures 1 to 11 As shown, a gantry 34 is fixedly installed on the back of the outer frame 1. A longitudinal drive assembly 35 is fixedly installed on the inner wall of the gantry 34. A transverse drive assembly 36 is fixedly installed on the outer wall of the longitudinal drive assembly 35. One end of the transverse drive assembly 36 is fixedly connected to the laser cutting head 33. When performing laser cutting and drilling, the laser cutting head 33 will be moved under the action of the longitudinal drive assembly 35 and the transverse drive assembly 36, thereby adjusting the position of the laser cutting head 33. After the position is adjusted, the laser cutting head 33 is started, and the laser cutting head 33 performs cutting and drilling on the surface of the workpiece.

[0044] like Figures 1 to 9 As shown, a mounting base 37 is fixedly installed on the top of the outer frame 1, and the drive motor 16 is fixedly installed on the inner side of the mounting base 37. A force-bearing seat 38 is symmetrically fixedly installed on the outer wall of the outer frame 1. Support legs 39 are symmetrically fixedly installed on the bottom of the force-bearing seat 38. A base 40 is fixedly installed between the bottoms of the support legs 39. A vertical plate 43 is symmetrically fixedly installed between the top of the base 40 and the bottom of the feeding rack 42. The drive motor 16 is fixed by the mounting base 37, providing a fulcrum for the drive motor 16, enabling it to provide power for the operation of the device. The support legs 39 are fixed to the outer frame 1 by the force-bearing seat 38, supporting the outer frame 1 and keeping it at a suitable height for easy use. The base 40 increases the contact area between the device and the ground, thereby increasing the overall stability of the device.

[0045] Working principle: During the cutting process, the metal workpiece to be drilled is placed inside the feed box 5. The workpiece enters the feed box 5 and rolls to the top of the lifting seat 3 under its own gravity. Then, the drive rod 2 is activated, which pushes the lifting seat 3 upward. The lifting seat 3 moves a workpiece upward between the channel plates 6. When the workpiece moves to the rotating roller 4, the rotating roller 4 limits the workpiece at the top, thus achieving automatic feeding and automatic fixing. After the workpiece is fixed, the laser cutting head 33 is moved by the longitudinal drive component 35 and the transverse drive component 36. When the laser cutting head 33 moves to the appropriate position, it starts working and performs cutting and drilling on the metal workpiece.

[0046] After the metal workpiece completes one cutting operation, the drive motor 16 starts, driving the drive wheel 17 to rotate. The drive wheel 17 drives the driven wheel 18 to rotate via the transmission belt 19. When the driven wheel 18 rotates, it drives the rotating roller 4 to rotate via the rotating shaft 9. The metal workpiece is located between the rotating roller 4 and the support roller 20. Under the action of the rotating roller 4, the metal workpiece will rotate, thereby adjusting the angle of the metal workpiece. By changing the angle of the metal workpiece, the device can perform cutting operations at different positions on the surface of the metal workpiece according to the requirements, without the need for manual adjustment, increasing the convenience of using the device.

[0047] When the metal workpiece is moved upwards and fixed, it will come into contact with the material collection trough 45. Before cutting, the workpiece is rotated by the drive motor 16. During rotation, the material collection trough 45 scrapes and cleans the workpiece surface, removing any impurities that may be adhering to it, thus ensuring the cutting effect of subsequent cutting. Before adjusting the angle after each cutting operation, the workpiece is driven to reciprocate by the drive motor 16. Since the material collection trough 45 is located between the two rotating rollers 4, and the workpiece cutting position is also located between the two rotating rollers 4, therefore... When the workpiece reciprocates, the cutting edge of the workpiece will swing between the two rotating rollers 4. The collecting groove 45 will repeatedly grind at the cutting position, thereby grinding away the abnormal protrusions caused by laser heating at the cutting position. This avoids interference between the abnormal protrusions and the rotating rollers 4 and the support rollers 20 when adjusting the angle, which would cause the angle to deviate when the workpiece rotates, thus ensuring the processing accuracy of the workpiece. The impurities cleaned by the collecting groove 45 will accumulate on the inner side of the collecting groove 45. The collecting groove 45 can be removed by the cooperation of the locking block 44 and the locking groove, which makes it easier to deal with the impurities in the collecting groove 45.

[0048] When the metal workpiece is cut, the drive rod 2 retracts, causing the lifting seat 3 to descend along the inside of the channel plate 6 with the workpiece. As the lifting seat 3 descends, it passes through the extrusion baffle 15, which comes into contact with the lifting seat 3. Under the pressure of the extrusion baffle 15, the lifting seat 3 flips over. After flipping, the lifting seat 3 overlaps with the discharge box 32. The metal workpiece that has been cut on the lifting seat 3 slides down the inclined lifting seat 3 into the discharge box 32 under the action of gravity. Finally, the metal workpiece slides down into the feeding rack 42 through the discharge box 32 for collection, thus achieving the effect of automatic discharge. Afterward, the drive rod 2 moves the lifting seat 3 upward to prepare for the next cutting operation. When the lifting seat 3 moves upward, it will be reset under the action of the elastic element A13.

[0049] When the lifting seat 3 moves the workpiece upward for cutting, the receiving plate 7 moves upward and drives the support plate 14 upward. When the support plate 14 moves upward, it blocks one end of the feed box 5, thus preventing the workpiece from entering the inner side of the channel plate 6 and jamming the device, causing malfunction. When the lifting seat 3 moves downward to send the cut workpiece out of the device, the receiving plate 7 moves downward and drives the support plate 14 downward. When the support plate 14 moves downward, it meshes with the gear roller 23. When the support plate 14 meshes with the gear roller 23, it drives the gear roller 23 to rotate. When the gear roller 23 rotates, it causes the lifting baffle 25 that meshes with it to move upward. After moving upward, the lifting baffle 25 blocks one end of the feed box 5, thus preventing all the workpieces in the feed box 5 from falling out during discharge and affecting the use of the device.
