[0004] However, for outer spherical bearings, there is currently no effective measure or method to control the change in the size of the outer circle of the bearing after stamping the seal
In addition, for the outer spherical and cylindrical bearings of the same specification, the radial wall thickness of the sealing groove of the outer spherical bearing is smaller than that of the cylindrical surface. Ellipse, at the same time, the R of the outer spherical surface will become larger, which will seriously affect the installation between the bearing and the bearing seat

Abstract
The invention discloses a sealing piece punching device. The sealing piece punching device comprises a punching mold, a spring module and an outer ring; the spring module and the outer ring coat the outer surface of the punching mold in sequence; the upper end of the spring module is fixed on the punching mold, and the lower end of the spring module is contacted with the upper end surface of the outer ring; the inner surface of the outer ring is step-shaped; the outer surface of the punching mold is step-shaped; the step surface of the outer ring is matched with the step surface of the punching mold; the outer ring can move up and down on the outer surface of the punching mold; and the inner surface of the head part of the outer ring is an inclined surface. The sealing piece punching device can solve a series of problems of the outer spherical surface bearing generated after punching assembly of a sealing piece; and the problems include outer diameter size increment of an outer circle, increment of an ellipse and R increment of an outer spherical surface.
Description
technical field [0001] The invention relates to the field of bearing manufacturing equipment, in particular to a seal stamping device capable of controlling the expansion and deformation of the outer circle of an outer spherical bearing. Background technique [0002] For sealed bearings, the assembly of the seal is usually to use an auxiliary device to stamp the seal into the seal groove of the outer ring of the bearing. In this process, the head of the seal is stamped and installed into the seal groove of the outer ring after being deformed by force. At the same time, the sealing groove of the outer ring of the bearing will also be subjected to a reverse force, which makes the outer diameter of the bearing have a tendency to expand outward, and the size of the outer circle will become larger, and due to the unevenness of the force, the outer circle of the bearing will The tendency of outward expansion is also uneven, which in turn produces a large ellipse. In short, after ...
