[0002] The corrugated tube rolling forming device forms the corrugated tube by continuously rolling the tube blank with rollers. The roller acts on the tube blank according to a certain trajectory and pressure, so that the tube blank material gradually forms a corrugated shape. The rolling forming process can realize continuous production and significantly improve the production efficiency of the corrugated tube.

[0003] In the existing public documents, the patent announcement number CN118357324A discloses a corrugated tube rolling forming device. This technology makes the metal tube and the tensioning die rotate synchronously with the disc, and the tensioning die rotates under the action of the transmission element, so that the outer wall of the metal tube is squeezed between the first corrugated groove and the second corrugated groove, and the rolling is realized during the rotation process, so that the inner and outer corrugated structures are formed on the metal tube. The processing technology is simple, the forming quality is stable, and the operation is convenient. However, this technology has the following defects: During the rolling process of the corrugated pipe, the tube blank of the corrugated pipe needs to be extruded. During the extrusion process, the lateral position of the tube blank of the corrugated pipe is very easy to shake when rolling, and the two sides and the top position are very easy to shake.
