Magnetic rolling processing device for inner surface of long round tube

Abstract

The invention combines a magnetic field control technology and a rolling technology, is applied to rolling processing of the inner surface of a long and circular tube, and belongs to the field of special processing. A magnetic rolling processing device for the inner surface of the long and circular tube comprises an external magnetic field generator located outside the long and circular tube and amagnetic rolling tool located inside the long and circular tube; the external magnetic field comprises external magnetic circuit magnetic poles; and the external magnetic circuit magnetic poles forma rotating magnetic field through circumferential rotation and perform axial feeding along the central axis of the long and circular tube to drive the rotating magnetic field to perform axial feeding.By the aid of the device, the problem that rolling processing of the inner surface of the long and circular tube cannot be completed through traditional rolling processing is solved.

Description

technical field [0001] The invention combines the magnetic field control technology and the rolling technology, and is applied to the rolling processing of the inner surface of the long round tube, belonging to the field of special processing. Background technique [0002] The existing rolling technology is to use tools made of materials with higher hardness (such as hardened steel, hard alloy and ruby, etc.), to apply a certain pressure on the surface of the processed part, so that the metal on the surface of the part will be plastically deformed, and the metal will be changed. The organizational structure and physical properties of the surface layer are used to achieve the purpose of smoothing and strengthening the surface of the workpiece. Rolling processing is often used to process inner circular surfaces, cylindrical surfaces, conical surfaces, open arc surfaces, screw thread surfaces, gear tooth surfaces, planes, and some special-shaped surfaces that are not easy to pr...

Problems solved by technology

Rolling processing is often used to process inner circular surfaces, cylindrical surfaces, conical surfaces, open arc surfaces, screw thread surfaces, gear tooth surfaces, planes, and some special-shaped surfaces that are not easy to process. Particularity, the existing rolling processing method cannot complete the rolling processing of the inner wall, which reduces the use value of the long round pipe to a certain extent
