Under the condition that a crankshaft cannot be ground, a plurality of large-sized shaft workpieces adopt a rolling processing technology to achieve a better effect in order to meet the surface roughness requirement in the technical requirements of drawings. The rolling process can cause the surface of the workpiece to be instantaneously and transiently softened at high temperature, and the rolled workpiece can cause the metal of the wave crest after turning to be filled in the wave trough, and cause the surface to generate certain plastic deformation, thereby realizing the change of the size and the roughness of the part. The roughness of the rolled surface can reach Ra1.6mu m-Ra1.8mu m.
By rolling the excircle, cylindrical surface, conical surface and plane of the workpiece, the surface hardness of the workpiece can be improved besides the surface roughness of the workpiece.

The existing rolling technology has the following problems: reference may be made to fig. 6.
(1) The rolling force is small, the structure is complex, the function is single, for example, three-axis control rolling is realized, the mechanical arm controls one side of material adding, and nine-axis linkage debugging is complex and difficult.
(2) The whole structure is inconvenient to disassemble, most of the whole structure is only suitable for single hot rolling or single cold rolling, and the whole structure cannot realize single material adding or single rolling functions, only has the function of simultaneously adding the materials and has few functions.
(3) The rolling process can not be realized for structures such as transverse and longitudinal inclined ribs and the like in large-size workpieces.
(II) in terms of material molding: and (5) a rolling bending process.
The rolling and bending purposes of the present profile mainly comprise two aspects, namely, rolling a straight plate material into a rolling and bending profile with a given curvature radius, and recovering a waste plate material which does not meet the specification in the process into a straight material.
The existing roll bending process has the following problems.
(1) For the rolling and bending process, the simple rolling equipment mostly adopts a four-axis or three-axis double-roller structure, and the multi-roller process is not clear.

When the active supporting roller 10 controls the barrel 12 to rotate in the x direction, rolling of the longitudinal ribs 16 in the barrel 12 can be achieved. When the auxiliary supporting roller 9 controls the barrel 12 to rotate in the y direction, rolling of the transverse ribs 17 (annular ribs) in the barrel 12 can be achieved. Rolling of ribs (not shown) inside the tub 12 can be achieved when the active support roller 10, the auxiliary support roller 9 simultaneously control the tub 12 to rotate in the xy-plane.
The invention adopts force-position hybrid control and is matched with a pressure sensor, a position sensor and visual identification, so that the accurate control of position and pressure can be realized.
