Description

Technical Field

[0001] The invention relates to the technical field of stamping devices, in particular to a stamping device used for bearing processing. Background Art

[0002] The stamping device used for bearing processing is a mechanical device that can quickly process and shape metal. During the processing of the bearing, a retainer needs to be installed inside the bearing to ensure the installation stability of the ball. The retainer is usually a metal ring.

The waste generated by the stamping falls into the waste slot 403. After the stamping processing, the limit assembly 2 is manually moved to one side of the drive shaft 501 , so that the installation shaft 204 is engaged with the card slot 506, and the correction head 208 is pushed to move toward the inner wall of the ball retainer 3 by the propulsion cylinder 207, so that the correction head 208 contacts the inner wall of the ball retainer 3 and applies pressure to the ball retainer 3, and the ball retainer 3 is driven to rotate at a uniform speed again by the driving motor 405, so that several correction heads 208 correct one side of the ball retainer 3 to restore the deformed position. After correction, the propulsion cylinder 207 drives the correction head 208 to be recovered, and the limit assembly 2 is removed. The friction plate 508 is reset by the telescopic cylinder 507, so that the friction plate 508 is separated from the ball retainer 3, and the processed ball retainer 3 is removed from the drive shaft 501, and the stamping process of the ball retainer 3 is completed.
