Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a stamping device for a bearing retaining ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.

[0003] Some bearing retaining rings are formed by one-time stamping during production, and some are processed after stamping to save materials to reduce the residual materials after arc stamping. When bending the stamped retaining rings, the traditional stamping and bending device not only easily deforms the retaining rings but also makes it difficult to remove the materials. For this reason, we provide stamping equipment for bearing retaining rings to solve the above problems. Utility Model Content

[0013] 3) Beneficial effects:

[0014] Compared with the prior art, the stamping equipment for the bearing retaining ring has the following beneficial effects:

[0015] 1. The utility model installs an external shaft on the punching machine so that the pressing frame carries the first forming block to press the material, so that the material is pressed against the inner side of the groove of the punching seat. At the same time, the groove on the surface of the first forming block prevents the material from deforming during the punching process. The first telescopic rod is started to push the extrusion block so that the two ends of the material that are raised are squeezed into the groove of the second forming block by the extrusion block, so that the retaining ring forms a whole arc, achieving the effect of using the groove to limit the shape of the retaining ring to prevent deformation during punching, and solving the problem that the retaining ring is easily deformed and bent due to stress after the secondary punching.

[0016] 2. The utility model adjusts the stripping rod so that the pressing rod is above the two ends of the punched material. After the first forming block rises, the pressing rod presses the material to make it separate from the first forming block. By starting the transverse motor to drive the transverse threaded rod to rotate, the first forming block slides along the guide rod to separate from the position where the material is located. The stripping is completed by rotating the retaining ring so that the retaining ring notch separates from the second forming block, thereby achieving the effect of gradual demolding and solving the problem of difficulty in demolding after the retaining ring is formed.
