Description

Technical Field

[0001] This utility model relates to the field of laser cutting, and in particular to a high-oxygen laser cutting device. Background Technology

[0002] High-oxygen laser cutting equipment uses a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate, forming a hole. Oxygen, as an assist gas, reacts with the metal being cut, undergoing an oxidation reaction that releases a large amount of heat. Simultaneously, it blows molten oxides and melts out of the reaction zone, creating a cut in the metal. Because the oxidation reaction during cutting generates a large amount of heat, high-oxygen laser cutting requires less energy and has a faster cutting speed.

[0003] However, in existing high-oxygen laser cutting equipment, after the workpiece is cut, all the workpieces remain on the worktable and must be removed before the next workpiece can be cut, thus affecting the cutting efficiency.

[0004] Therefore, it is essential to invent a high-oxygen laser cutting device. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings: Example

[0032] Reference Figure 1-8 A high-oxygen laser cutting device includes a base, a workpiece conversion table, a high-oxygen laser cutting head 1, and anti-collision devices 2, wherein: one side of the base is fixedly connected to the workpiece conversion table, the high-oxygen laser cutting head 1 is fixedly installed on the base, and a plurality of anti-collision devices 2 are evenly fixedly installed on the bottom of the high-oxygen laser cutting head 1.

[0033] Specifically, the machine base includes a base, an electric linear guide rail 7, a slide plate 8, and a gantry 9. The electric linear guide rail 7 is fixedly installed on the base so that the gantry 9 can be driven by the electric linear guide rail 7 to move the electric linear guide rail 91, the electric linear guide rail 92, and the high-oxygen laser cutting head 1 horizontally reciprocating above the workpiece placement table 20. The gantry 9 is slidably installed on the base. The gantry 9 is fixedly connected to the output end of the electric linear guide rail 7 through the slide plate 8. The slide plate 8 is slidably connected to the base so as to ensure the stability between the gantry 9 and the electric linear guide rail 7.

[0034] Specifically, an electric linear guide rail 2 91 is fixedly installed on the crossbeam of the gantry frame 9, and an electric linear guide rail 3 92 is fixedly installed at the output end of the electric linear guide rail 2 91, so as to ensure the stability of the electric linear guide rail 2 91 and the electric linear guide rail 3 92 through the gantry frame 9.

[0035] Specifically, the electric linear guide rail 2 91 is arranged perpendicularly to the electric linear guide rail 3 92 and the electric linear guide rail 1 7;

[0036] Specifically, the electric linear guide rail 2 91 is set parallel to the crossbeam of the gantry 9 so that the electric linear guide rail 3 92 and the high-oxygen laser cutting head 1 can be driven to move horizontally through the electric linear guide rail 2 91;

[0037] Specifically, the electric linear guide rail 392 and the electric linear guide rail 17 are arranged perpendicularly to each other so that the distance between the high oxygen laser cutting head 1 and the workpiece placement stage 20 can be adjusted by the electric linear guide rail 392.

[0038] Specifically, the high-oxygen laser cutting head 1 is fixedly mounted on the output end of the electric linear guide rail 3 92 via the mounting base 93;

[0039] Mounting base 93 adopts a clamp-type mounting base, which facilitates the disassembly and assembly of the high-oxygen laser cutting head 1;

[0040] Specifically, the workpiece conversion table includes an electric rotary table 19 and a workpiece placement table 20. One side of the electric rotary table 19 is fixedly connected to the base. Four workpiece placement tables 20 are evenly and fixedly installed at the output end of the electric rotary table 19. The workpiece placement tables 20 are located above the base and below the high-oxygen laser cutting head 1.

[0041] By setting up the workpiece transfer table, during use, the workpiece to be cut is placed on each of the workpiece placement tables 20. Then, the electric rotary table 19 drives the workpiece placement tables 20 to rotate, so that one of the workpiece placement tables 20 carries the workpiece to directly below the high-oxygen laser cutting head 1 and stops rotating. The high-oxygen laser cutting head 1 can then cut the workpiece on the workpiece placement table 20. After cutting, the electric rotary table 19 drives the workpiece placement table 20 to rotate again, so that the cut workpiece is moved out directly below the high-oxygen laser cutting head 1. Then, another workpiece placement table 20 carries the workpiece to directly below the high-oxygen laser cutting head 1 and stops rotating, and the cutting continues, thereby improving the cutting efficiency.

[0042] Specifically, the base includes a first frame plate 3, a second frame plate 4, a connecting plate 5, a linear guide rail 6, and a stop 10. A connecting plate 5 is fixedly installed on each side between the first frame plate 3 and the second frame plate 4. The first frame plate 3 and the second frame plate 4 are arranged in parallel. The first frame plate 3 and the second frame plate 4 are arranged perpendicularly to the connecting plate 5. A linear guide rail 6 is fixedly installed on each side between the first frame plate 3 and the second frame plate 4. The linear guide rail 6 is above the connecting plate 5. The two vertical plates of the gantry frame 9 are slidably connected to the corresponding linear guide rail 6. A stop 10 is fixedly installed above the first frame plate 3 and the second frame plate 4 to shield the electric linear guide rail 7 and prevent cutting debris from affecting the electric linear guide rail 7. The electric linear guide rail 7 is fixedly installed between the first frame plate 3 and the second frame plate 4 and is arranged perpendicularly between the first frame plate 3 and the second frame plate 4. The electric linear guide rail 7 and the slide plate 8 are below the stop 10 to ensure the overall stability of the base.

[0043] Specifically, the high-oxygen laser cutting head 1 includes a housing 11, a communication socket 12, a main air inlet head 13, a secondary air inlet head 14, a laser cutting head 15, a main oxygen nozzle 16, and a secondary oxygen nozzle 17. The laser cutting head 15 is fixedly installed inside the housing 11, and the output end of the laser cutting head 15 protrudes from the bottom of the housing 11. The communication socket 12 of the laser cutting head 15 is fixedly installed at the top of the housing 11 so that the laser cutting head 15 can be connected to the laser cutting machine host through the communication socket 12. The main oxygen nozzle 16 and the secondary oxygen nozzle 17 are fixedly installed at the bottom of the housing 11. The main oxygen nozzle 16 and the auxiliary oxygen nozzle 17 are evenly distributed on both sides of the laser cutting head 15. The target spray points of the main oxygen nozzle 16 and the auxiliary oxygen nozzle 17 coincide with the output points of the laser cutting head 15. This allows for increased oxygen supply at the workpiece cutting point during cutting, thanks to the arrangement of the main oxygen nozzle 16 and the auxiliary oxygen nozzle 17. The main air inlet 13 of the main oxygen nozzle 16 and the auxiliary air inlet 14 of the auxiliary oxygen nozzle 17 are both fixedly installed on the top of the housing 11 to allow connection with an external oxygen supply device.

[0044] Specifically, a recess 18 is provided at the bottom of the outer shell 11. The output end of the laser cutting head 15, as well as the main oxygen nozzle 16 and the auxiliary oxygen nozzle 17, are all located in the recess 18 so as to protect the laser cutting head 15, the main oxygen nozzle 16 and the auxiliary oxygen nozzle 17 from collision with the workpiece.

[0045] Specifically, the anti-collision device 2 includes an anti-collision post 21, a support head 24, a rotating shaft 25, a torsion spring 26, a support base 27, and a rotating cavity 28. The support head 24 is fixedly installed at one end of the anti-collision post 21, and the rotating shaft 25 is fixedly installed on the upper part of the support head 24. The torsion spring 26 is sleeved on the rotating shaft 25. The support base 27 is fixedly installed at the bottom of the outer shell 11, and the rotating cavity 28 is opened on the support base 27. The rotating shaft 25 is rotatably installed in the rotating cavity 28 through the torsion spring 26. This can prevent direct contact between the high-oxygen laser cutting head 1 and the workpiece. At the same time, when side contact occurs, the anti-collision device 2 has a good buffer space to prevent hard contact.

[0046] The bottom of the anti-collision post 21 is flush with the bottom of the outer shell 11.

[0047] Specifically, a pressure sensor 22 is fixedly installed at the other end of the anti-collision post 21. When the pressure sensor 22 comes into contact with the workpiece, it sends a signal to the controller, causing the controller to control the electric linear guide rail 3 92 to stop driving the high-oxygen laser cutting head 1 to move downward. A displacement sensor 23 is fixedly installed on the side of the anti-collision post 21 near the support base 27. When the side of the anti-collision post 21 comes into contact with the workpiece and tilts, the displacement sensor 23 is triggered and sends a signal to the controller, causing the controller to control the electric linear guide rail 2 91 and the electric linear guide rail 1 7 to stop running. The wiring harness 29 of the pressure sensor 22 and the displacement sensor 23 extends from the anti-collision post 21 and the support head 24 and is electrically connected to the controller.

[0048] The controller is a PLC controller, and the input terminals of the PLC controller are electrically connected to the pressure sensor 22 and the displacement sensor 23.

[0049] The output of the PLC controller is electrically connected to electric linear guide rail 1 (7), electric linear guide rail 2 (91), and electric linear guide rail 3 (92).

[0050] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
