Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a laser cutting machine tool for pipe fittings. Background Technology

[0002] Pipe laser cutting machines are commonly used for cutting pipes. For example, Chinese utility model patent publication number "CN218799894U" discloses a fiber laser cutting machine for thin pipes, which includes a frame placed on the ground, a cutting section fixed to the frame, and a pushing section slidably mounted on the frame. The cutting section includes a placement body placed on the frame and a laser cutter placed on the side wall of the placement body away from the pushing section. A placement hole, which is a through hole, is provided on the side wall of the placement body near the placement hole. A clamping component for positioning and fixing the pipe is provided on the placement body near the placement hole. The pushing section includes a pushing body that slides with the frame and a pushing column that rotates with the pushing body. The axis of the pushing column coincides with the axis of the placement hole. A fixing component for positioning and fixing the pipe is provided on the end face of the pushing column. This application has the effect of improving the stability of the pipe during cutting.

[0003] However, the aforementioned laser cutting machine lacks an automatic feeding structure. When in use, workers need to manually lift the pipe to the designated position, then fix and cut it. The feeding process usually requires multiple people to participate at the same time, which is a waste of manpower and time. Furthermore, after the pipe is cut, the cut part will fall directly to the ground under the action of gravity, which makes the pipe susceptible to impact and damage, thus reducing product quality.

The feeding bed 3 is provided with two sets of grooves 21 symmetrically arranged. A lead screw 31 is rotatably arranged in both sets of grooves 21. A moving block 35 is provided on the moving plate 4. The moving block 35 is threadedly connected to the lead screw 31 and slidably arranged in the groove 21. A third motor 30 is provided on the feeding bed 3. One end of the lead screw 31 is located on the output shaft of the third motor 30.

[0027] A crossbeam 26 is provided on the gantry frame 22, and a lifting unit is provided on the crossbeam 26. A support plate 27 is provided on the lifting unit. The lifting unit includes a third hydraulic cylinder 28 and a guide rod 29. The third hydraulic cylinder 28 is located on the crossbeam 26, the support plate 27 is located on the output shaft of the third hydraulic cylinder 28, and the guide rod 29 is located on the support plate 27 and slides through the crossbeam 26.

[0028] The feeding unit 8 includes a drive wheel 10, a driven wheel 11, a conveyor belt 12, and a conveyor support 13. The conveyor support 13 is mounted on the base plate 1. The drive wheel 10 and the driven wheel 11 are both rotatably mounted on the conveyor support 13. The drive wheel 10 and the driven wheel 11 are symmetrically arranged. The conveyor belt 12 is sleeved on the drive wheel 10 and the driven wheel 11. Several sets of stops 19 are evenly spaced on the conveyor belt 12. The drive wheels 10 in the several sets of feeding units 8 are connected by a drive shaft 33. The driven wheels 11 in the several sets of feeding units 8 are connected by a driven shaft 34. A fourth motor 32 is mounted on one set of conveyor supports 13 at the edge. One end of the drive shaft 33 is mounted on the output shaft of the fourth motor 32.

[0029] The lifting unit 9 includes a first hydraulic cylinder 14, a lifting plate 15, a bidirectional threaded rod 16, and a clamping plate 17. The first hydraulic cylinder 14 is mounted on the base plate 1. The lifting plate 15 is mounted on the output shaft of the first hydraulic cylinder 14. The lifting plate 15 is provided with a sliding groove 20. The bidirectional threaded rod 16 is rotatably mounted in the sliding groove 20. The clamping plate 17 is threadedly connected to the bidirectional threaded rod 16 and slidably mounted in the sliding groove 20. Two sets of clamping plates 17 are symmetrically arranged. The lifting plate 15 is provided with a second motor 18. One end of the bidirectional threaded rod 16 is mounted on the output shaft of the second motor 18.

[0030] The laser cutting assembly 7 includes a second hydraulic cylinder 23, a mounting plate 24, and a laser cutting head 25. The second hydraulic cylinder 23 is mounted on the gantry 22, the mounting plate 24 is mounted on the output shaft of the second hydraulic cylinder 23, and the laser cutting head 25 is mounted on the mounting plate 24.

[0031] In practical use, the pipes are automatically transported to the conveyor belt 12 by an external pipe conveyor (not shown in the figure). The stop block 19 set on the conveyor belt 12 can limit the pipes and prevent them from rolling without restriction on the conveyor belt 12. The fourth motor 32 can drive the drive shaft 33 to rotate, the drive shaft 33 drives the drive wheel 10 to rotate, and the drive wheel 10 drives the conveyor belt 12 to move the pipes. Once the pipe is moved to the lifting unit 9, the first hydraulic cylinder 14 is activated, causing the lifting plate 15 to rise and contact the pipe. At this point, the pipe is positioned between the two sets of clamping plates 17. Then, the second motor 18 is activated, driving the bidirectional threaded rod 16 to rotate. The bidirectional threaded rod 16 causes the two sets of clamping plates 17 to move closer together. The two sets of clamping plates 17 can clamp the pipe, maintaining its stability during lifting, and also center the pipe on the lifting plate 15, making it easier to clamp the pipe subsequently using the chuck 6. After the clamping plates 17 have clamped the pipe, the first hydraulic cylinder 14 continues to lift the lifting plate 15 until the pipe's axis coincides with the axis of the chuck 6. Then, the chuck 6 secures one end of the pipe. After the pipe is secured, the fourth motor 32 is started, which drives the lead screw 31 to rotate. The lead screw 31 moves the moving plate 4, which in turn moves the chuck 6 and the pipe, so that the cut end of the pipe rests on the receiving support plate 27. The receiving support plate 27 ensures the stability of the pipe during cutting and also catches the cut pipe to prevent it from falling and getting damaged. The third hydraulic cylinder 28 can raise and lower the receiving support plate 27, allowing its height to be adjusted according to usage requirements. After the pipe is positioned, the laser cutting head 25 can then cut the pipe. During cutting, the first motor 5 drives the chuck 6 and the pipe to rotate, and the second hydraulic cylinder 23 can adjust the height of the laser cutting head 25.

[0032] In summary, this solution can automatically transport the pipe to the lifting unit 9 via the feeding unit 8. The lifting unit 9 can then lift the pipe to the chuck 6, where one end of the pipe can be clamped and fixed. This allows for automatic pipe feeding, resulting in a higher degree of automation and saving manpower and time. Furthermore, the solution uses the receiving and lifting plate 27 to support the cut end of the pipe. This ensures the stability of the pipe during the cutting process and also catches the cut pipe to prevent it from falling and getting damaged.
