Description

Technical Field

[0001] This utility model belongs to the field of straight seam welded pipe processing technology, specifically relating to a device for treating scars on straight seam welded pipes. Background Technology

[0002] Straight seam welded pipe refers to steel pipes made by welding hot-rolled or cold-rolled steel plates or strips into straight seams on welding equipment. Due to its simple production process, high production efficiency, and low cost, this method of steel pipe production has developed rapidly. During production, long strips of steel of a certain specification are formed into round pipes using a high-frequency welding unit and then welded into round pipes. After welding, a scar is easily left at the weld seam, which requires a treatment device to clean it.

[0003] However, traditional cleaning devices mostly rely on manual hand-held grinders to grind the blemishes on steel pipes. This method is not only cumbersome to operate, but also reduces the efficiency of blemish removal when the steel pipe is long. Furthermore, it is difficult to collect the residue during the blemish removal process, which can have a certain impact on the working environment, making it impractical.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Then, by controlling the cylinder 5, the output end drives the lifting frame 6 and the second conveyor roller 7 downwards, so that they come into contact with the straight seam welded pipe on the upper end of the first conveyor roller 3. Then, the motor 25 is controlled to drive the synchronous belt 24 and the synchronous pulley 23 to rotate multiple rotating shafts 2, so that the first conveyor roller 3 and the second conveyor roller 7 feed the straight seam welded pipe, thereby making... During the feeding process, the scraper 13 cleans the weld scars to further increase the scar removal efficiency. During the scar removal process, the user can turn on the negative pressure fan 21 to create negative pressure inside the pipe 18 and the conical head 17, so that the scraped metal impurities enter the conical head 17 and then enter the impurity removal box 19 through the pipe 18. After the scraping operation is completed, the baffle 27 and the impurity removal box 19 can be separated by removing the bolts. At this time, the impurities inside the impurity removal box 19 can be taken out through the notch 26 for continued use.
