[0003] The existing welded pipe processing and straightening equipment has the following disadvantages during use:

[0004] When a bent welded pipe is inserted into a straightening device for straightening, one end of the bent welded pipe needs to be manually inserted between the rotating upper and lower distribution rollers. However, this will cause one end of the welded pipe to be unable to enter quickly when inserted, resulting in low feeding efficiency, thereby greatly reducing the overall working efficiency of the equipment. Therefore, a welded pipe processing and straightening device is needed. Utility Model Content
