Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, and particularly relates to a nitrogen-making welding machine. Background Art

[0002] In a nitrogen-making welding machine, a welding torch uses high-energy laser pulses to locally heat a material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. In high-power laser welding, an auxiliary protective gas (such as nitrogen) is blown to prevent the metal material from sputtering and contaminating the focusing mirror, and also to prevent excessive focusing of the plasma generated during the welding process, which blocks the laser from reaching the material surface.

[0003] In order to enable the welding torch to operate more flexibly, the cable connected to the welding torch is set to be relatively long. Therefore, when the nitrogen-making welding machine is in a non-use state, the cable will be placed in a mess, not only occupying space, but also the long cable may become a tripping hazard, increasing the safety hazard in the workplace, and it is easy for workers or other personnel to be tripped by the long cable.

[0004] It can be seen that the existing technology still needs to be improved. Content of the Utility Model

[0005] In view of the deficiencies of the above-mentioned existing technology, the purpose of the present utility model is to provide a nitrogen-making welding machine, aiming to be able to regularly store the cable connected to the welding torch.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] A nitrogen-making welding machine includes a chassis, a laser, a nitrogen generator, a chiller and a controller arranged in the chassis, and a welding torch arranged outside the chassis. The controller controls the laser, the nitrogen generator, the chiller and the welding torch to work. The wiring of the laser, the nitrogen generator, the chiller and the controller connected to the welding torch converges on a single cable, and a cable winder for winding and storing the cable is provided on the top of the chassis.

[0008] As a further improvement of the above technical solution, the cable winder includes 4 elastic pieces and an intermediate connecting part for connecting one end of the 4 elastic pieces together. The 4 elastic pieces are spaced 90° from each other in space and form a "cross-shaped" radial structure; each elastic piece is bent in a "Z" shape.

[0009] As a further improvement of the above technical solution, the cable winder includes 3 elastic pieces and an intermediate connecting part for connecting one end of the 3 elastic pieces together. The 3 elastic pieces are spaced 120° from each other in space and form a "herringbone-shaped" radial structure; each elastic piece is bent in a "Z" shape.

[0010] As a further improvement of the above technical solution, the wire reel includes a turntable rotatably arranged on the top of the chassis and a motor arranged inside the chassis for driving the turntable to rotate.

[0011] As a further improvement of the above technical solution, a fixing seat for fixing the welding torch is arranged on the side of the chassis, and a profiling groove adapted to the body of the welding torch is formed on the fixing seat.

[0012] As a further improvement of the above technical solution, the chassis includes a main box body, a control panel arranged on the front face of the main box body, a vertical partition plate arranged inside the main box body, and side door panels arranged on both sides of the main box body. A chiller and a laser are arranged on one side of the vertical partition plate, and a nitrogen generator is arranged on the other side.

[0013] As a further improvement of the above technical solution, the nitrogen generator is fixed on the vertical partition plate through a limit hoop.

[0014] As a further improvement of the above technical solution, the laser is supported by a laminate, and the laser is located above the chiller.

[0015] As a further improvement of the above technical solution, universal wheels are arranged at the bottom of the main box body.

[0016] The beneficial effects of the present utility model: Compared with the prior art, by arranging a wire reel on the top of the chassis, the long cable can be neatly stored on the top of the chassis, reasonably utilizing the space on the top of the chassis instead of being randomly scattered, realizing the effective management and winding of the cables connecting the welding torch and various components inside the chassis. This not only avoids the cables from being scattered at the work site, reduces the occurrence of safety accidents such as tripping, and improves the safety of the working environment; but also effectively saves the space of the working area and keeps the working environment clean and orderly.

Detailed implementation mode

[0023] The present utility model provides a nitrogen - making welding machine. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further details the present utility model with reference to the attached drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0024] Please refer to Figure 1-Figure 5 The present utility model provides a nitrogen - making welding machine, which includes a chassis 1, a laser 2, a nitrogen generator 3, a chiller 7 and a controller (such as MCU, PLC and other types of controllers) arranged in the chassis 1, and a welding torch (not shown in the figure) arranged outside the chassis 1. The controller controls the laser 2, the nitrogen generator 3, the chiller 7 and the welding torch to work. The wires connecting the laser 2, the nitrogen generator 3, the chiller 7 and the controller to the welding torch are gathered on a single cable (not shown in the figure). A wire reel 4 for winding and storing the cable is provided at the top of the chassis 1.

[0025] Compared with the prior art, by arranging the wire reel 4 at the top of the chassis 1, the present utility model enables the long cable to be neatly stored at the top of the chassis 1, reasonably utilizes the space at the top of the chassis 1, rather than being randomly scattered, realizes the effective management and winding of the cable connecting the welding torch and each component in the chassis 1. It not only avoids the cable from being scattered at the work site, reduces the occurrence of safety accidents such as tripping, and improves the safety of the working environment, but also effectively saves the space of the working area and keeps the working environment clean and orderly.

[0026] It should be understood that the orderly management of the cable reduces the inconvenience caused by cable entanglement when the welding torch moves, and improves the flexibility and efficiency of the welding operation.

[0027] Please refer to Figure 1In a first embodiment, the cable reel 4 includes four spring pieces 41 and an intermediate connecting portion 42 for connecting one end of the four spring pieces 41 together. The intermediate connecting portion 42 is riveted to the top of the chassis 1. Each spring piece 41 is bent in a "Z" shape. The "Z"-shaped bent spring piece 41 design provides stronger support and elasticity, and can firmly fix cables of different lengths and weights. It is not easy to deform or loosen even under heavy loads. The four spring pieces 41 are spaced 90° apart in space and form a "cross-shaped" radial structure; the staff manually winds the cable around the four spring pieces 41. The "cross-shaped" radial structure allows the cable to be evenly distributed in four directions, avoiding cable entanglement and knotting, speeding up the cable reeling and releasing speed, and improving work efficiency.

[0028] See also Figure 2 In the second embodiment, the cable reel 4 includes three spring pieces 41 and an intermediate connecting portion 42 for connecting one end of the three spring pieces 41 together. The intermediate connecting portion 42 is riveted to the top of the chassis 1. Each spring piece 41 is bent in a "Z" shape. The "Z"-shaped bent spring piece 41 design provides better elasticity and rigidity, and can maintain its shape when bearing a heavy cable, thereby enhancing the structural strength of the entire cable reel 4. The three spring pieces 41 are spaced 120 degrees apart in space and form a "herringbone" radial structure; the staff manually winds the cable around the three spring pieces 41. The "herringbone" radial structure evenly distributes the cable in three directions, ensuring that the load on the cable is evenly distributed, avoiding excessive force on one side, and improving the stability of the cable retraction and release.

[0029] See also Figure 3 In the third embodiment, the cable reel 4 includes a turntable 43 rotatably mounted on the top of the chassis 1 and a motor 44 disposed within the chassis 1 for driving the turntable 43. Compared to manual operation, the turntable 43 driven by the motor 44 can automatically wind and release the cable, greatly reducing the operator's physical labor and improving work efficiency.

[0030] Preferably, a mounting base 6 for securing the welding gun is provided on the side of the chassis 1. This mounting base 6 is provided with a contoured groove 61 that matches the gun body of the welding gun. When not in use, the welding gun can be securely placed on the mounting base 6, preventing accidental activation or dropping of the welding gun due to haphazard placement, thereby reducing workplace safety risks. It should be noted that the mounting base 6 can be made of silicone, which imparts deformable elasticity to the mounting base 6. The welding gun has an interference fit with the contoured groove 61, ensuring a precise fit on the mounting base 6. This prevents the welding gun from detaching from the mounting base 6 and falling during transport of the nitrogen welding machine.

[0031] In this embodiment, the chassis 1 includes a main box body 50, a vertical partition 51 disposed inside the main box body 50, and side door panels 52 disposed on both sides of the main box body 50. A chiller 7 and a laser 2 are provided on one side of the vertical partition 51, and a nitrogen generator 3 is provided on the other side. Since the laser 2 and the chiller 7 usually generate more heat, placing them on the same side can more effectively utilize the cooling system, improve the heat exchange efficiency, and ensure that the equipment can still maintain good temperature control under long-term high-load operation. Through physical partitioning, the possible electromagnetic interference or airflow influence between the laser 2 and the nitrogen generator 3 can be reduced, improving the stability and accuracy of the equipment.

[0032] To prevent the nitrogen generator 3 from vibrating and shifting when the nitrogen production welding machine moves, as shown in Figure 5 shown, the nitrogen generator 3 is fixed to the vertical partition 51 by a limit hoop 53; the design of the limit hoop 53 ensures that the nitrogen generator 3 is firmly fixed to the vertical partition 51, avoiding equipment displacement caused by vibration or movement, and improving the stability and safety of equipment operation.

[0033] Furthermore, as shown in Figure 4 shown, the laser 2 is supported by a layer board 54, and the laser 2 is located above the chiller 7. By being supported by the layer board 54, the laser 2 can be vertically stacked above the chiller 7, making full use of the vertical space, immediately obtaining the cooling effect provided by the chiller 7, contributing to rapid heat dissipation, keeping the laser 2 within the optimal working temperature range, and improving the operation efficiency and stability of the equipment.

[0034] Preferably, universal wheels are provided at the bottom of the main box body 50, enabling the equipment to easily move between different working areas, so that the nitrogen production welding machine can flexibly move to different locations to complete welding work.
