Description
Technical Field
[0001] This utility model relates to the field of welding technology, and in particular to a welding device for stainless steel pipes. Background Technology
[0002] In industrial production, stainless steel pipes are widely used in many fields such as construction, chemical industry, and food due to their excellent corrosion resistance and high strength. Welding of stainless steel pipes is a key step in its processing, and the quality of welding directly affects the performance and service life of stainless steel pipe products. With the development of the industry, the demand for stainless steel pipe welding is becoming increasingly diversified. It not only requires high welding efficiency, but also the ability to cope with various complex working conditions and stainless steel pipes of different specifications. Therefore, it is particularly important to develop a high-performance and highly adaptable stainless steel pipe welding device.
[0003] Currently, the stainless steel pipe welding devices commonly available on the market each have their own characteristics in terms of mechanical structure and technical principle. In terms of mechanical structure, most adopt a relatively traditional and fixed clamping mode. Among them, the simple clamping structure is more common. It uses bolts to tighten the clamp, thereby fixing the stainless steel pipe in a specific position. In terms of technical principle, as far as laser welding devices are concerned, the laser generator produces a high-energy-density laser beam, which is precisely guided to the welding head through the beam transmission system. During welding, the focused laser beam irradiates the part of the stainless steel pipe to be welded, causing the metal to quickly absorb energy and instantly heat up to the melting point or even the boiling point, achieving fusion connection. Other traditional welding devices, such as arc welding equipment, rely on the arc generated between the electrode and the workpiece to release heat, melting the welding rod to achieve welding.
[0004] However, existing welding equipment has a problem: it is difficult to adapt to stainless steel pipes of different diameters. Due to the lack of flexibility in its clamping structure, it cannot be conveniently and effectively adjusted according to the pipe diameter. This leads to the need to frequently change different specifications of clamps when facing welding tasks with multiple pipe diameters. The operation is cumbersome and time-consuming, which greatly reduces production efficiency. In addition, impurities generated during the welding process, such as metal shavings and fumes, will be scattered in the working environment, which not only pollutes the working environment, but also seriously threatens the health of workers if inhaled for a long time. Therefore, a stainless steel pipe welding device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a welding device for stainless steel pipes, which aims to improve the problem that the existing technology cannot adapt to stainless steel pipes of different diameters.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] As a further description of the above technical solution:
[0016] A filter plate is slidably connected inside the collection box, and a handle is fixedly connected to the top of the filter plate. The separator mesh and the filter plate are symmetrically distributed inside the collection box.
[0017] As a further description of the above technical solution:
[0018] A fan is provided between the separator and the filter plate, and a support block is fixedly connected to the side wall of the fan.
[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the output ends of the hydraulic devices at both ends first drive the second slider to make relative linear motion. The second slider drives the slide plate and roller to make linear motion in the same direction, which limits the stainless steel pipe. When the laser machine starts working, the output end of the motor drives the roller to make clockwise motion in the same direction, which rotates the stainless steel pipe clockwise and performs laser welding. This achieves the effect of limiting stainless steel pipes of different diameters, solves the problem that traditional welding devices cannot adapt to stainless steel pipes of different diameters, and improves the applicability of the device.
[0025] 2. In this utility model, the operator first turns on the working button of the collection box by operating the button. The fan starts to suck in the impurities generated during the welding process. Larger impurities will be separated by the separator, while smaller impurities will pass through the separator and be blocked by the filter plate, eventually falling into the drawer. This achieves the effect of collecting impurities, solves the problem of impurities affecting the working environment, and improves the cleanliness of the working environment.

[0034] The dust collection assembly includes a collection box 14, which is made of galvanized steel sheet. A separator mesh 15, made of woven stainless steel, is slidably connected inside the collection box 14. Its function is to initially intercept larger particles of impurities generated during welding, preventing them from entering subsequent filtration stages. A handle 16, made of rubber, is fixedly connected to the top of the separator mesh 15, facilitating installation and removal by the operator to clean the intercepted impurities. A filter plate 21, made of high-efficiency fiber filter material, is slidably connected inside the collection box 14 to further filter smaller particles of impurities that pass through the separator mesh 15, purifying the exhaust gas generated during welding. A handle 22, made of the same material as handle 16, is fixedly connected to the top of the filter plate 21, facilitating operation by the operator.

Its outer shell is made of plastic, and the fan blades are made of aluminum alloy. Support blocks 20 are fixedly connected to the side wall of the fan 19. The function of the fan 19 is to generate suction, drawing the waste gas containing impurities generated during the welding process into the collection box 14. After being filtered by the separator 15 and the filter plate 21, the purified air is discharged, thus protecting the welding environment. This is existing technology and will not be elaborated further here.

The operator can easily pull out the drawer 17 through the second handle 18 to clean and treat the impurities collected inside.
[0035] Working principle: When using the stainless steel pipe welding device, the operator first drives the slider 10 to make relative linear motion according to the size of the stainless steel pipe through the output end of the hydraulic device 11 at both ends of the control plate 2. The movement of the slider 10 drives the slider 4 to make linear motion inward on the guide rail 3. The slider 4 drives the slide plate 5 and the roller 7 to make linear motion inward. At this time, the operator places the stainless steel pipe between the rollers 7. The rollers 7 at both ends limit the stainless steel pipe. At this time, the laser machine 13 starts to weld the stainless steel pipe. At the same time, the output end of the motor 8 drives the roller 7 to make clockwise circular motion, which drives the stainless steel pipe to make the same circular motion, so that the laser machine 13 can fully weld the surface of the stainless steel pipe.
[0036] While the laser machine 13 is welding, the operator first turns on the working button of the collection box 14 by operating the button. The fan 19 inside the collection box 14 begins to suck in the impurities generated during the welding process. Larger impurities are separated by the separator 15, while smaller impurities pass through the separator 15 and are blocked by the filter plate 21, eventually falling into the drawer 17. After welding is completed, the operator can remove the drawer 17 by the handle 2 18 to further process the impurities inside. The separator 15 and filter plate 21 can also be removed for easy cleaning, achieving the effect of collecting impurities and purifying the air.
