Description

Technical Field

[0001] This utility model relates to the field of galvanized pipe processing technology, specifically to a galvanized pipe production and processing device. Background Technology

[0002] Galvanized pipe is a type of pipe whose corrosion resistance is improved by galvanizing the surface of the steel pipe. By immersing the steel pipe in molten zinc, a zinc-iron alloy layer and a pure zinc layer are formed. The galvanized layer is thick and has strong corrosion resistance, so it is widely used.

[0003] After the pipe-making machine welds the galvanized steel strip into pipes and cuts the galvanized pipes into multiple shorter sections, weld beads may remain on the outer and inner surfaces of the galvanized pipes. Therefore, the weld beads need to be cleaned in time. Otherwise, the galvanized pipes may crack, which will damage the smooth and flat appearance of the weld and reduce the strength.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] Please see Figure 1-6This utility model provides a galvanized pipe production and processing device, including a base 1, a frame 2 fixed on the base 1, a ramp 3 on the inner bottom surface of the frame 2, a discharge pipe 4 fixed at the port of the ramp 3, inspection covers 5 fixed at both ends of the frame 2 by bolts, a feed port 6 on one side of the inspection cover 5, a pipe fitting 7 installed in the feed port 6, a drive motor 8 fixed on the other side of the inspection cover 5, a three-head support 9 fixed on the inner wall of the frame 2, a forward and reverse motor 10 fixed on the three-head support 9, a conveyor wheel 11 fixed at the output end of the forward and reverse motor 10, and a weld bead cleaning structure installed inside the frame 2.

[0027] The weld bead cleaning structure includes a drive gear 12, which is fixed to the output end of the drive motor 8. A bearing ring 13 is installed inside the frame 2, and a driven gear 14 rotates inside the bearing ring 13. A linkage gear 15 meshes between the drive gear 12 and the driven gear 14, and the linkage gear 15 is rotatably connected to the inspection cover 5 via a rotating shaft. A drive shaft 16 is fixed to the drive gear 12, and an inner spiral scraper 17 is fixed to the drive shaft 16. A rotating sleeve 18 is fixed to the driven gear 14, and the other end of the rotating sleeve 18 is rotatably connected to the frame 2 via the bearing ring 13. A discharge port 19 is provided on the rotating sleeve 18, and an outer spiral scraper 20 is fixed to the inner wall of the rotating sleeve 18. Both the outer surface of the 17 and the inner surface of the outer spiral scraper 20 are provided with ball bearings 21. The pipe 7 can be inserted into the frame 2 through the feed port 6. The forward and reverse motor 10 can drive the pipe 7 to move inward and stop through the conveyor wheel 11, which can clamp and fix the pipe 7. Then, the drive motor 8 is started to drive the drive gear 12 to rotate. The drive gear 12 drives the inner spiral scraper 17 to rotate through the drive shaft 16. The drive gear 12 can drive the driven gear 14 to rotate through the linkage gear 15. The driven gear 14 can drive the outer spiral scraper 20 to rotate through the rotating sleeve 18. Therefore, the weld beads on the surface of the pipe 7 can be scraped clean by the inner spiral scraper 17 and the outer spiral scraper 20.

[0028] Furthermore, multiple balls 21 are arranged along the spiral direction of the inner spiral scraper 17 and the outer spiral scraper 20 respectively. During the rotation of the inner spiral scraper 17 and the outer spiral scraper 20, the balls 21 also roll on the surface of the pipe fitting 7, thus making it easier for the inner spiral scraper 17 and the outer spiral scraper 20 to rotate on the surface of the pipe fitting 7 via the balls 21.

[0029] Furthermore, the inner spiral scraper 17 and the ball 21 are in contact with the inner wall of the pipe fitting 7, and the outer spiral scraper 20 and the ball 21 are in contact with the outer surface of the pipe fitting 7. Therefore, the inner spiral scraper 17 and the outer spiral scraper 20 can reduce the friction between themselves and the pipe fitting 7 through the ball 21, and prevent the inner spiral scraper 17 and the outer spiral scraper 20 from causing the pipe fitting 7 to rotate due to excessive friction during rotation.

[0030] Furthermore, the pipe fitting 7 is located between the inner spiral scraper 17 and the outer spiral scraper 20. Both the inner spiral scraper 17 and the outer spiral scraper 20 include a spiral ring and a spiral blade. The spiral ring has a rectangular cross-section, and the spiral blade has an isosceles trapezoidal cross-section. The difference is that in the structure of the inner spiral scraper 17, the spiral ring is fixed on the drive shaft 16, while the spiral blade is fixed on the outside of the spiral ring and contacts the outer surface of the pipe fitting 7. In the structure of the outer spiral scraper 20, the spiral ring is fixed on the rotating sleeve 18, while the spiral blade is fixed on the inside of the spiral ring and contacts the inner wall of the pipe fitting 7. This makes it convenient for the inner spiral scraper 17 to scrape off the inner weld beads on the inner surface of the pipe fitting 7, and for the outer spiral scraper 20 to scrape off the outer weld beads on the outer surface of the pipe fitting 7.

[0031] Furthermore, one end of the three-head bracket 9 is fixedly connected to the frame 2, and the other two ends are respectively fixed with forward and reverse motors 10, so that the forward and reverse motors 10 at both ends can be supported and fixed by the three-head bracket 9. The forward and reverse motors 10 are model 6RK200RGU-CF and support forward and reverse rotation.

[0032] Furthermore, three three-headed brackets 9 are arranged around the circumference of the pipe 7. The output ends of two adjacent forward and reverse motors 10 are fixedly connected to the conveyor wheel 11 between them, so that the forward and reverse motors 10 at both ends of the three-headed brackets 9 can drive the conveyor wheel 11 between them to rotate synchronously and in the same direction, thereby enabling the conveyor wheel 11 to drive the pipe 7 to move.

[0033] Furthermore, three conveying wheels 11 are arranged around the circumference of the pipe fitting 7, and all three conveying wheels 11 are in contact with the surface of the pipe fitting 7, so that the pipe fitting 7 can be moved axially by the conveying wheels 11, and a section of the pipe fitting 7 can also be clamped and fixed by the three conveying wheels 11.

[0034] The working principle of this utility model is as follows: During use, a short section of welded galvanized steel strip pipe 7 is placed into the frame 2 through the feed inlet 6. The forward and reverse motor 10 is started, driving the conveyor wheel 11 to rotate, continuing to move the pipe 7 inward. Then, the forward and reverse motor 10 stops, and the conveyor wheel 11 clamps and fixes the pipe 7. After the pipe 7 moves into the frame 2, it is positioned between the inner spiral scraper 17 and the outer spiral scraper 20. The drive motor 8 is then started, driving the drive gear 12 to rotate. The drive gear 12, through the drive shaft 16, drives the inner spiral scraper 17 to rotate. The drive gear 12, through meshing with the linkage gear 15, drives the driven gear 14 to rotate. The driven gear 14, through the rotating sleeve 18, drives the outer spiral scraper 20 to rotate. Therefore, during the rotation of the inner spiral scraper 17, the pipe... The inner weld beads on the inner wall of the pipe 7 are scraped and cleaned. During the rotation of the outer spiral scraper 20, the outer weld beads on the outer surface of the pipe 7 are scraped and cleaned. The drive motor 8 stops rotating, and then the forward and reverse motor 10 drives the conveyor wheel 11 to reverse, removing the pipe 7. Then, the other end of the pipe 7 is inserted into the frame 2. The above operation is repeated to clean both ends of the pipe 7 step by step, thereby quickly cleaning the weld beads on the surface of the pipe 7. In addition, the weld beads scraped by the outer spiral scraper 20 first fall into the rotating sleeve 18, and then fall onto the ramp 3 through the discharge port 19 and are discharged through the discharge pipe 4. During the process of pulling the pipe 7 outward, the inner spiral scraper 17 can scrape out the weld beads that fall into the inside of the pipe 7. The scraped weld beads fall into the rotating sleeve 18 and can also be discharged through the discharge pipe 4.

[0035] 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.
