Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically to an ultra-thin stainless steel laser welding device. Background Technology

[0002] With the advancement of technology and industrial development, ultra-thin stainless steel materials have been widely used in aerospace, automotive manufacturing, precision instruments, medical equipment, and many other fields due to their excellent corrosion resistance, high strength, and beautiful appearance. However, the welding process of ultra-thin stainless steel materials faces many challenges. Traditional welding methods, such as arc welding and gas shielded welding, often fail to achieve ideal welding results when welding ultra-thin stainless steel. Traditional welding methods also suffer from drawbacks such as slow welding speed and unstable weld quality, making it difficult to meet the requirements of modern manufacturing for high-quality and high-efficiency welding technology. To solve these problems, laser welding technology has emerged. Laser welding is a method that uses a high-energy laser beam as a heat source and achieves rapid, precise, and high-quality welding between materials by precisely controlling parameters such as the power, focal length, and movement speed of the laser beam. Laser welding technology has significant advantages in the welding of ultra-thin stainless steel.

[0003] However, most existing welding devices have relatively simple fixing structures, resulting in poor fixing effects and causing movement during the welding of ultra-thin stainless steel, thus leading to poor welding results. Therefore, they do not meet the current requirements. To address this, we propose an ultra-thin stainless steel laser welding device. Utility Model Content

[0028] Working Principle: In use, first, place the entire ultra-thin stainless steel laser welding device in the working area, ensuring the base component 2 is stable and level.

Adjust and fix the clamping mechanism 5 according to the type and size of the workpiece. Adjust the clamping position by sliding the movable sleeve 51 on the longitudinal rod component 50. Rotate the knob component 54 to fix it in the knob bolt groove 53, thereby fixing the position of the movable sleeve 51 and the mounting support plate 55.

Simultaneously, the second moving motor 65 is activated, its pulleys slidably engaged with the groove of the crossbeam slide rail component 60, driving the entire laser welding machine movable slide rail frame 6 to move on the horizontal plane, expanding the working range. Once the laser welding machine body 8 has moved to the predetermined position via the laser welding machine movable slide rail frame 6, the laser emitter head 9 begins operation, emitting a high-energy laser beam. The laser beam is focused on the joint of the workpiece to be welded, and the stainless steel material rapidly melts due to the laser energy, forming a weld. Simultaneously, the air blowing pipe 10 blows inert gas onto the weld to protect it from oxidation and ensure welding quality. After welding is completed, the laser emitter head 9 and the air blowing pipe 10 are shut off. Release the workpiece by adjusting the clamping mechanism 5 and remove the welded stainless steel component. Inspect the weld quality to ensure that the weld strength and appearance meet the requirements. Reset the laser welding machine's moving slide rail 6 to its initial position and turn off the first moving motor 64 and the second moving motor 65. Clean the welding table 4 and adjust the clamping mechanism 5 to remove spatter and impurities generated during welding. Regularly check the wear condition of each component of the device and replace damaged parts in a timely manner to ensure long-term stable operation of the device.
