Abstract

The invention discloses a novel hydraulic wear-resisting sealing ring and a machining process. The novel hydraulic wear-resisting sealing ring comprises a sealing ring body, a groove and an oil discharge trough. The groove is formed in the edge of one side of the inner diameter of the sealing ring body. The oil discharge trough is correspondingly formed in the other face, opposite to the groove, of the sealing ring body. The machining process comprises the following steps of firstly, raw material selecting, secondly, raw material mixing, thirdly, injection molding, fourthly, turning and fifthly, checking and packaging. Components comprise, by weight percent, 100-150 parts of modified TPU, 2-3 parts of a tackifier, 2-3 parts of phyllosilicate powder, 2-3 parts of a release agent and 2-3 parts of color masters. According to the novel hydraulic wear-resisting sealing ring and the machining process, the occupational hazard brought by the situation that employees are in contact with the dust process is thoroughly eradicated; and the process that nonferrous metal (bronze powder) is used as a filling material is omitted, and the danger brought by the nonferrous metal to the environment iseradicated.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a novel wear-resistant sealing ring for hydraulic pressure and its processing technology. Background technique [0002] The piston rod wear-resistant ring on the market is made of polytetrafluoroethylene (PTFE) + bronze powder + toner. After being mixed by a high-speed mixer, the material is filled into the mold cavity by powder metallurgy processing method, and a certain amount of pressure is applied by a press. It is pressed and formed by pressure, and then the billet is calcined and shaped by a high-temperature sintering furnace using a programmed calcination method, and finally the finished product is obtained by CNC lathe processing. [0003] In the production process of the prior art, high-temperature sintering of copper powder + tetrafluoroethylene will produce toxic gases; copper powder and tetrafluoroethylene will produce dust during high-speed mixing, and polytetr...
