[0002] Stainless steel pipe is widely used in architectural decoration (such as guardrail, handrail), industrial pipeline (chemical industry, petroleum), mechanical equipment (medical equipment, food processing) and other fields due to corrosion resistance, high strength and other characteristics. Edge rolling forming is one of the key processes of stainless steel pipe processing, which is used to manufacture elbow, flange, annular component and other special-shaped parts, or used in pipeline connection, structure support and other scenes.

[0003] And traditional equipment can only process single steel pipe each time, leading to long single-batch processing time, and tedious manual pipe-by-pipe feeding and centering operation.

By setting multiple pressing grooves and limiting grooves on the pressing roller and rotating roller, independent and coordinated processing stations are formed, which can simultaneously limit and fix multiple steel pipes and bend them into shape, realizing synchronous edge rolling. Compared with the traditional single-pipe sequential processing mode, this mode shortens single-batch processing time and improves production efficiency. At the same time, processing multiple steel pipes together can reduce the tedious operation of manual pipe-by-pipe feeding, meeting the demand for efficiency and flexibility in batch processing scenarios.

[0011] Through the above technical scheme, the output end of the driving motor is directly connected with the compression roller, forming a rigid transmission structure, reducing the power loss and transmission gap of the traditional transmission mechanism.

[0012] Further, the compression groove is located in the same plane as the corresponding limiting groove.

[0013] Through the above technical scheme, the compression groove and the corresponding limiting groove are located in the same plane, so that the stress point and the support point of the steel pipe are coaxially aligned during the rolling process.

[0014] Further, the lower end of the fixed plate is fixedly connected with the upper end of the main plate, and the inner wall of each of the three fixed plates is rotatably connected with the outer wall of the rotating roller, wherein each group comprises two fixed plates.

[0015] Through the above technical scheme, each group of fixed plates comprises two symmetrically arranged fixed plates, which are rotatably connected with the outer wall of the rotating roller, thereby reducing the radial shaking of the rotating roller during high-speed rotation.
