Description
Technical Field
[0001] The utility model relates to the technical field of pipe expanding equipment, in particular to an automatic pipe expanding and forming equipment for pipes. Background Technique
[0002] Pipe expanding is a process of processing thin pipes into thicker pipes using different techniques. This processing method is called pipe expanding, also known as hot pipe expanding. After the steel pipe undergoes the hot pipe expanding process, its material remains unchanged. Welded pipes and seamless pipes are both applicable to this process. Currently, most of the pipe expanding equipment uses manual loading and unloading by personnel, which easily causes damage due to the pipe body falling or safety problems. Moreover, most pipe expanding operations are one-way, which will affect the efficiency of pipe expanding and forming. Therefore, we propose an automatic pipe expanding and forming equipment for pipes. Content of the Utility Model
