In addition, if the main parameters of the cnc pipe end forming machines automatic bend grinding tool arc groove are not selected properly, it can not strengthen the wall thickness of the bending position, then under the action of compressive earth stress, due to the instability of the wall thickness, the critical state force at the inner edge of the pipe is low, resulting in wave folds. In summary, the thick-walled seamless steel pipe is easy to cause wrinkles and defects when bending. Therefore, when designing the bending abraded tool for thick wall seamless steel pipe, the main structural parameters must be clearly defined effectively to facilitate the bending of seamless steel pipe. Under the action of the grinding tool, the water pipe will produce a pre-loading reaction speed to resist the oval deformation caused by the bending of the thick wall seamless steel pipe, and effectively control the wrinkle defect in the bending position.
