Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, and particularly relates to a stamping device for producing C-shaped sealing rings. Background Technique

[0002] The C-shaped sealing ring belongs to an axially self-tightening sealing ring, which is named after the cross-section of the sealing gasket being C-shaped. When the end cover is tightened with high-pressure bolts, the C-shaped ring is axially compressed to generate a pre-tightening sealing specific pressure. When the container pressure rises, the C-shaped ring will generate axial expansion, thereby generating an axial self-tightening force, increasing the sealing specific pressure to achieve the effect of self-tightening sealing. It realizes the axial self-tightening sealing of the elastic gasket, can adapt to large axial displacements of the connection system. The C-shaped sealing ring is mainly used in large devices such as automobiles, ships, and construction machinery, and has an important position in the connection part, ensuring the stable operation of the device. During the production process of the C-shaped sealing ring, a stamping device is required. However, during the use of the existing stamping device for producing C-shaped sealing rings, due to the shape characteristics of the C-shaped sealing ring, the opening is small, resulting in the inability to automatically fall after stamping, and manual removal is required, which is time-consuming and laborious, reduces the stamping efficiency, and is not conducive to the production and use of C-shaped sealing rings. Therefore, a stamping device for producing C-shaped sealing rings is proposed. Content of the Utility Model
