Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, specifically a steel pipe spigot forming machine. Background Technology

[0002] The ends of steel pipes need to be expanded to form a socket or spigot structure. Currently, steel pipe end forming machines are generally used to expand the pipe. The steel pipe end forming machine includes an inner mold with multiple inner modules forming a circle. The multiple inner modules can expand inward or outward to achieve deformation and stretching of the steel pipe.

[0003] In the existing steel pipe forming process, when the steel pipe comes into contact with the expander, the steel pipe is prone to displacement due to force, which causes the steel pipe to come into contact with the insert block. Under force, sliding will occur, resulting in deformation of the steel pipe. Furthermore, steel pipes of different sizes need to be expanded by inserts of different sizes so that the forming machine can shape steel pipes of different sizes. Therefore, a steel pipe insert forming machine is proposed. Utility Model Content
