Description

TECHNICAL FIELD

[0002] Flanges (flange plates) play a connecting and fixing role on automobiles and are widely applied to parts such as wheels, suspension systems and transmission systems. In the automatic production process of flanges, the machining precision is crucial and has an influence on the application of the flanges on automobiles.

[0003] Therefore, many automatic production processes for flanges are proposed in the prior art; for example, CN112792511B proposes a high-precision flange plate production and machining process, which comprises the following steps: S1, blank making: after the metal blank is heated to a high temperature, it is placed on a forging machine for forging, and the metal blank is forged into a flange plate blank with a circular hole in the middle and a circular ring structure; S2, blank machining: the flange plate blank obtained in step S1 is extruded, and the inner wall of the circular hole in the middle of the flange plate blank is supported, and the outer circular surface of the flange plate is extruded by a rotating compression roller. The second centering clamp hand on the two sides is driven to extend and retract by the corresponding second electric push rod, so that the second centering clamp hand can be adapted to the gradually increasing inner diameter and outer diameter of the flange plate blank after being extruded, and then adaptively retreat, so that the second centering clamp plate can effectively center and remove chips according to the outer circular surface of the flange plate.

[0004] However, the above technical solution and many flange machining processes in the prior art are similar, and in the surface chip removal, polishing and polishing machining stages in the machining process of the flange, the flange needs to be removed and replaced in the fixed position after the above machining is completed on one surface, and then the above machining is continued on the other surface.
