Description

Stamping die of bearing seal ring skeleton Technical Field The utility model relates to the technical field of bearing seal ring frameworks, in particular to a stamping die of a bearing seal ring framework. Background The bearing seal ring framework is an important component part of the bearing seal ring and is mainly used for improving the sealing performance and prolonging the service life of the bearing. The bearing seal ring is typically composed of an outer metal skeleton and an inner rubber ring. The metal skeleton provides structural support, while the rubber ring is responsible for the sealing function. The design of the metal framework may be single or double layer, depending on the application requirements. In the prior art, since the bearing seal ring framework is composed of the metal framework and the rubber ring, the metal framework and the rubber ring are required to be stacked together in the production process, and then the metal framework and the rubber ring are pressed together through the punch head to form a complete bearing seal ring framework, the metal framework and the rubber ring are required to be frequently aligned to ensure the pressing effect of the bearing seal ring framework, and the production efficiency of the bearing seal ring is low. Disclosure of utility model The application provides a stamping die for a bearing seal ring framework, which can be used for positioning a rubber ring, so that the rubber ring is not damaged when a metal framework and the rubber ring are pressed, and meanwhile, the pressing efficiency of the metal framework and the rubber ring is greatly improved, thereby improving the production efficiency of the bearing seal ring framework.
