Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to a flux removal device for steel pipe welding. Background Technology

[0002] Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. In the construction industry, steel pipes are used to manufacture building structural frames, columns, and mechanical supports, which can reduce weight. The most common production method for steel pipes is spiral seam welding. During welding, flux is usually applied to the weld area to protect the metal and improve weld quality. However, after welding, the flux can adhere to the weld area of ​​the steel pipe. If it is not removed in time, it will seriously affect the quality of the steel pipe in use.

[0003] As described in application number 202321748421.3, a prior art flux removal device for steel pipe welding involves rotating a roller during steel pipe welding, causing a striking block to move back and forth under the action of a reciprocating screw, thereby striking the weld slag formed during welding and automatically removing the slag from the surface of the steel pipe to clean the flux. However, this prior art is suitable for welding two sections of pipe. When cleaning multiple sections of pipe, the device or pipe needs to be moved after cleaning one end of the joint, resulting in inconvenient operation and poor flexibility. Therefore, this paper proposes a flux removal device for steel pipe welding to solve the above-mentioned problems. Utility Model Content

[0021] Please see Figure 1-5 This utility model provides a technical solution: a flux scraping device for steel pipe welding, which solves the problem of inflexibility in the use of existing technology, including a connecting plate 1 and a side plate 2, such as... Figure 1 As shown, the side plate 2 is fixedly installed on the top of the connecting plate 1. A groove 21 is provided on one side of the side plate 2. The diameter of the groove 21 is larger than the diameter of the pipe, which facilitates the limiting of the pipe and thus increases the stability of the pipe. The side plate 2 also includes a sliding groove 22, such as... Figure 3 As shown, a groove 22 is formed on the side plate 2, a slider 24 is slidably installed in the groove 22, and an electric push rod 23 is fixed to the top of the connecting plate 1. Its free end is fixedly connected to one side of the slider 24. When the electric push rod 23 is started, the electric push rod 23 drives the slider 24 to move longitudinally. The longitudinal movement of the slider 24 drives the fixed seat 5 to move longitudinally. The longitudinal movement of the fixed seat 5 drives the adjusting scraping structure 600 to move longitudinally.

[0022] Fixed base 5, fixed base 5 and slider 24 are fixedly connected on the other side, multiple sets of pipes 3 are welded together as one piece, and as... Figure 1 As shown, one end of the pipe 3 is embedded in the groove 21.

[0023] A fixing structure 400 is used to fix the pipe and improve its stability during flux removal. The fixing structure 400 includes a base plate 410 located on the other side of the pipe 3, a slide rail 420 on the base plate 410 with a connecting block (not shown) slidably installed inside the slide rail 420, a positioning plate 430 fixedly connected to the connecting block, and a groove 21 on the side of the positioning plate 430 near the pipe 3, an mounting plate 440 fixedly mounted on the top of the base plate 410, and a hydraulic cylinder 450 fixedly mounted on the side of the mounting plate 440 with its free end fixedly connected to the positioning plate 430. Driving the hydraulic cylinder 450 pushes the positioning plate 430 closer to the pipe 3, causing the groove 21 on the positioning plate 450 to embed into the other end of the pipe 3, thereby fixing the pipe 3, improving its stability, and facilitating subsequent flux removal.

[0024] The adjustable scraping structure 600 is used to scrape away welds on the pipe 3. The adjustable scraping structure 600 includes a motor 610, such as... Figure 2 As shown, the motor 610 is fixedly installed on one outer wall of the fixed base 5. A lead screw 620 is rotatably installed on the adjacent inner wall of the fixed base 5. A connecting block 630 is slidably installed inside the fixed base 5. The lead screw 620 passes through the connecting block 630 and is threadedly connected to it. A scraper 640 is arc-shaped and conforms to the shape of the pipe 3. The size of the scraper 640 is larger than the size of the pipe 3, meaning it can penetrate the pipe 3. The scraper 640 is fixedly connected to the connecting block 630 via a connector. Four sets of springs 641, in conjunction with the springs 641, allow the scraper 642 to conform to the pipe 3, thereby improving the welding scraping effect. Figure 4 As shown, it is fixedly installed on the inner wall of the scraper 640. Four sets of scrapers 642 are fixedly connected to the free ends of four sets of springs 641 respectively. When the motor 610 is started, the motor 610 drives the lead screw 620 to rotate. The rotation of the lead screw 620 drives the connecting block 630 to move laterally. The lateral movement of the connecting block 630 drives the scraper 640 to move laterally. The lateral movement of the scraper 640 causes the scraper 642 to scrape off the flux at the interface of the pipe 3. This structure can scrape off the flux at the interface of multiple sets of pipes 3. Compared with the prior art, it does not require changing the position of the pipe 3 or the device, thus improving the flexibility of use.

[0025] When in use, first insert one end of the pipe 3 into the groove 21, then start the electric push rod 23. The electric push rod 23 drives the slider 24 to move longitudinally. The longitudinal movement of the slider 24 drives the fixed seat 5 to move longitudinally. The longitudinal movement of the fixed seat 5 drives the adjusting scraping structure 600 to move longitudinally. Start the motor 610, and finally make the scraper 640 penetrate the pipe 3. Then the hydraulic cylinder 450 is driven, and the hydraulic cylinder 450 pushes the positioning plate 430 close to the pipe 3, so that the groove 21 on the positioning plate 450 is embedded into the other end of the pipe 3, thereby fixing the pipe 3. Then, the motor 610 is started, which drives the lead screw 620 to rotate. The rotation of the lead screw 620 drives the connecting block 630 to move laterally. The lateral movement of the connecting block 630 drives the scraper 640 to move laterally. The lateral movement of the scraper 642 causes the scraper 642 to scrape off the flux at the interface of the pipe 3. With the help of spring 641, scraper 642 can fit into pipe 3, thereby improving the effect of welding scraping.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
