Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The cage is also called the bearing retainer, which refers to the bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing. It is an important component of the bearing.

[0003] After retrieval, Chinese patent application No. 202121254195.4 discloses a punching device for processing a bearing retainer. The patent relates to a punching device for processing a bearing retainer, comprising a workbench with a bracket, a base is fixedly provided at one end of the top of the workbench, a mounting guide column is fixedly provided on the top of the base, a support plate is fixedly provided on the inner side wall of the mounting guide column, a placement disk driven by a driver is movably provided inside the support plate, a sliding pressure plate driven by a cylinder and slidably mounted on the mounting guide column is provided above the placement disk, a retainer pressure ring integrally formed with the placement disk is provided at the bottom of the sliding pressure plate, a sliding frame driven by a screw and slidably mounted on the workbench is provided on one side of the mounting guide column, and a puncher is installed on the sliding frame; the patent places the retainer to be punched on the outside of the placement disk, the cylinder drives the sliding pressure plate to move downward along the mounting guide column, the retainer pressure ring presses the retainer, and the motor drives the placement disk to rotate, thereby driving the retainer to rotate.

[0004] Although the above patent places the retaining frame to be punched on the outside of the placement plate, the cylinder drives the sliding pressure plate to move downward along the installation guide column, the retaining frame pressure ring presses the retaining frame, the motor drives the placement plate to rotate, and then drives the retaining frame to rotate, the screw drives the sliding frame to move so that the puncher contacts the retaining frame, and the surface of the retaining frame is punched with high punching accuracy.
