Description

Technical Field

[0001] The invention belongs to the field of roller forming, and in particular relates to a roller bending forming roller profiling tooling. Background Art

[0002] When manufacturing welded pipes, the unwinding strip steel is passed through multiple roller dies for continuous rolling. The roller dies are divided into flat rollers and vertical rollers. The flat rollers apply roller pressure to the strip steel from the horizontal direction, while the vertical rollers apply roller pressure to the strip steel from the vertical direction. The placement positions of the flat rollers and the vertical rollers are different, but the processing technology is the same. The rollers are fixed on the lathe to turn the side of the rollers, and the side of the rollers needs to be processed into an arc. In the prior art, it is not possible to process the side of the roller into an arc at one time when turning the roller. The lathe tool needs to be adjusted multiple times to turn the side of the roller into a complete arc. The disadvantage is that it requires a high level of experience for the workers and masters, and not only is the processing troublesome, but the accuracy cannot be guaranteed.
