Description

Technical Field

[0001] The utility model relates to the field of high-frequency welded pipe welding. Specifically, it relates to an automatic control device for high-frequency welded pipe welding. Background Art

[0002] High-frequency welded pipe technology has been widely used in modern industry due to its unique advantages. Its remarkable feature is the fast welding speed, which can complete the welding process in an extremely short time, greatly improving production efficiency. In addition, another important advantage of high-frequency welded pipe technology is the small heat-affected zone of welding, which means that the influence on the surrounding materials during the welding process is small, thereby reducing material deformation and damage and ensuring the quality of the welded pipe. High-frequency welded pipe technology is particularly suitable for welding thin-walled pipes and various metal pipes. Due to the skin effect and adjacent effect generated by high-frequency current, this technology can accurately butt joint steel plates and other metal materials to form strong and durable welds. This new welding process not only improves welding efficiency but also improves welding quality, becoming an indispensable part of modern industry.

[0003] However, the existing high-frequency welded pipe technology still has some limitations in practical applications. Although the welding speed and quality have been significantly improved, during the welding process, it is still necessary for workers to rotate the high-frequency welded pipe through a rotating component to adjust the welding position of the high-frequency welded pipe and ensure that two sections of high-frequency welded pipes can be fully and seamlessly welded. This manual operation link not only increases the labor intensity but also may affect the consistency of welding efficiency and quality. Summary of the Utility Model

One support seat 401 is fixedly connected to the workbench 1. Below the other support seat 401, there is a moving mechanism 5. The moving mechanism 5 includes a moving block 501 arranged below the support seat 401. A threaded rod 502 is threadedly connected inside the moving block 501. There is a first opening 503 on the workbench 1. The width of the first opening 503 matches the moving block 501. The threaded rod 502 is connected to a fixing plate 504 through a bearing.

[0027] For the convenience of understanding the above technical solutions of the present utility model, the working principle or operation method of the present utility model in the actual process will be described in detail below.

[0028] In practical applications, when two high-frequency welded pipes need to be welded, first start the electric telescopic rod 10 to drive the positioning plate 9 to move upward. When placing one of the high-frequency welded pipes, the high-frequency welded pipe can be placed into the inside of the rotating cylinder 402 from one end close to the driven gear 405, so that one end of the high-frequency welded pipe abuts against the positioning plate 9. Then, synchronously start the two electric push rods 403 to drive the clamping plates 404 to clamp the high-frequency welded pipe, which can fix one high-frequency welded pipe, making the welding position exactly below the welding gun 303. Then, reverse-start the electric telescopic rod 10 to drive the positioning plate 9 to move downward, and then place the other high-frequency welded pipe at a suitable position inside the other rotating cylinder 402 and fix it with the clamping plates 404. After the fixing is completed, start the driving motor 505 to drive the moving plate to move, so that one high-frequency welded pipe approaches the other high-frequency welded pipe to achieve the automatic butt joint of the two high-frequency welded pipes. Then, start the hydraulic telescopic rod 301 to drive the welding gun 303 to move downward, so that the welding gun 303 automatically moves downward. When the welding gun 303 contacts the high-frequency welded pipe, the pressure sensor 7 can sense the pressure and transmit the information to the controller 8. When the controller 8 receives the information, it can control the hydraulic telescopic rod 301 to stop moving downward. Finally, synchronously start the rotating motors 407 on the two support seats 401, which can drive the driving gear 406 to rotate. The rotation of the driving gear 406 drives the driven gear 405 to rotate, and the rotation of the driven gear 405 can drive the rotating cylinder 402 to rotate, thereby driving the two high-frequency welded pipes to rotate synchronously, enabling the rotary welding of the high-frequency welded pipes and realizing the automatic welding of the high-frequency welded pipes.

[0029] In summary, by means of the above technical solution of the present invention, by setting the clamping and rotating mechanism 4, starting the electric push rod 403 can drive the clamping plates 404 to clamp the two high-frequency welded pipes, and starting the rotating motor 407 can drive the high-frequency welded pipes to rotate, without manual rotation of the high-frequency welded pipes, realizing the automatic rotation of the high-frequency welded pipes, ensuring the welding quality of the high-frequency welded pipes, and by setting the positioning plate 9, when welding is required, the electric telescopic rod 10 can be started to drive the positioning plate 9 to move upward. When placing the high-frequency welded pipe, one end of the high-frequency welded pipe abuts against the positioning plate 9, which can determine the welding point and facilitate the welding gun 303 to weld the high-frequency welded pipe.
