Technical Field

[0001] The utility model relates to the technical field of floating seal ring processing, in particular to a mold for processing a highly wear-resistant floating seal ring. Background Art

[0002] The pump shaft extends outward through the pump body, and there is a gap between the rotating parts and the stationary parts. If the pressure inside the pump is greater than the external pressure, the fluid will leak out from the gap. If the suction end of the pump is in a vacuum state, air will flow into the pump through the gap, seriously affecting the operation of the pump. In order to reduce leakage, a shaft end sealing device is installed at the gap. Floating ring seal is a type of shaft end seal. It is a non-contact dynamic seal that relies on the extremely small gap between the floating metal ring and the shaft or housing to limit fluid leakage. It is referred to as floating ring seal.

[0003] By processing the mold, in the process of stamping the metal ring of the sealing ring, the upper mold extrude and stamp the metal ring under the action of the stamping force, and finally a sealing ring can be formed under the action of the ring groove. After stamping, the formed annular ring is not easy to be picked up by hand, and the hand cannot clamp it, and it is difficult to take it out with force, which causes the problem of difficulty in taking out the metal sealing ring. For this reason, a high wear-resistant floating sealing ring processing mold is proposed. Utility Model Content
