Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting device. Background Technique

[0002] Laser cutting uses a high-power density laser beam to penetrate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporating to form holes. As the beam moves relative to the material, the holes continuously form a very narrow slit, completing the cutting of the material. Compared with the traditional contact cutting method, laser cutting has the advantages of non-contact, good cutting quality, high cutting efficiency, and fast cutting speed.

[0003] For example, in the utility model patent with the publication number CN210649071U, a laser cutting machine with a protection device is disclosed, including a laser cutting machine housing. A laser cutting machine door is movably connected to the middle of the top of the front of the laser cutting machine housing. A storage cabinet is fixedly installed on the left side of the bottom of the front of the laser cutting machine housing. A drawer is inserted into the right side of the bottom of the front of the laser cutting machine housing. A slide rail is fixedly connected to the front inside of the laser cutting machine housing. By setting the laser cutting machine housing and the laser cutting machine door, the effect of isolating laser debris is achieved.

[0004] However, when this utility model is in use, when batch cutting sheet materials, after the sheet materials are placed on the laser mesh support plate, laser cutting is carried out. After the laser cutting is completed, the sheet materials are taken out first, and then the next sheet materials are placed. After the next sheet materials are placed, cutting is carried out again. The material changing waiting time is relatively long, and the working efficiency is low. Summary of the Utility Model

[0023] Example: According to the attached drawings of the specification Figures 1-3It can be seen that during use, when batch cutting sheet materials, place the first sheet material on the first workbench 7. Starting the second reduction motor 21 can drive the rotation of the rotating shaft 22. The rotation of the rotating shaft 22 can drive the rotation of a pair of driving bevel gears 20. The rotation of a pair of driving bevel gears 20 can drive the rotation of a pair of driven bevel gears 19. The rotation of a pair of driven bevel gears 19 can drive the rotation of a pair of second threaded rods 4.

The rotation of the second threaded rods 4 can drive the rotation of a pair of second gears 17. The rotation of a pair of second gears 17 can drive the rotation of a pair of first gears 18. The rotation of a pair of first gears 18 can drive the rotation of a pair of first threaded rods 6. Since the first gear 18 meshes with the second gear 17, the rotation directions of the first gear 18 and the second gear 17 are opposite.

The rotation of a pair of first threaded rods 6 can drive two pairs of first sliders 5 to move to the left. The leftward movement of two pairs of first sliders 5 can drive the first workbench 7 to move to the left. The leftward movement of the first workbench 7 can move the first sheet material under the machine housing 15. Starting the first reduction motor 16 can drive the rotation of the fourth threaded rod 14. The rotation of the fourth threaded rod 14 can drive the lateral movement of the movable frame 11. The lateral movement of the movable frame 11 can drive the lateral movement of the laser cutting head 9. Starting the third reduction motor 23 can drive the rotation of the third threaded rod 28. The rotation of the third threaded rod 28 can drive the longitudinal movement of the movable block 24. The longitudinal movement of the movable block 24 can drive the longitudinal movement of the laser cutting head 9. The telescopic movement of the hydraulic cylinder 10 can drive the vertical movement of the laser cutting head 9. The laser cutting head 9 can cut the first sheet material. When the laser cutting head 9 cuts the first sheet material on the first workbench 7, the second sheet material can be placed on the second workbench 3. After the first sheet material is cut, reversing the second reduction motor 21 can drive the rotating shaft 22 to rotate in the opposite direction, thereby enabling the second workbench 3 to move to the left and the first workbench 7 to move to the right, thus moving the second sheet material under the machine housing 15, so that the laser cutting head 9 can cut the second sheet material. When the laser cutting head 9 cuts the second sheet material on the second workbench 3, the first sheet material on the first workbench 7 can be taken out and the third sheet material can be placed on the first workbench 7. When the second sheet material is cut, starting the second reduction motor 21 can move the second sheet material to the right and move the third sheet material to the left for cutting, thereby reducing the waiting time for material change and improving work efficiency.
