[0033] It should be noted that the utility model is an operating table for bending locomotive welded pipes. When in use, the steel pipe is stored in the storage barrel 6, and the steel pipe below falls to the top of the conveying roller 17 in the casing 2. The second motor 19 drives the conveying roller 17 to rotate. When the receiving groove 18 corresponds to the steel pipe, the steel pipe enters the receiving groove 18 and then rotates with the conveying roller 17.

Then the first motor 12 reverses, and the second moving frame 20 and the first moving frame 13 reversely move and reset, and the guide wheel 25 gradually enters the inclined groove 26 from the flat groove 27. When in the inclined groove 26, the positioning block 23 begins to move downward to press the steel pipe, and then the bending motor 9 is controlled to drive the driving arm 5 to rotate through the bending shaft 28. The driving arm 5 drives the first bending roller 3 to rotate around the second bending roller 4 to achieve bending of the steel pipe. The same is true for subsequent loading, and the loading will push out the bent steel pipe.
