Flexible joint forming method |
| abstract |
The invention discloses a flexible joint forming method. The flexible joint comprises a movable inverted cone shell, a reinforcing piece, a fixed rear joint and an elastic piece, wherein the movable inverted cone shell, the reinforcing piece and the fixed rear joint are metal pieces; Using isoprene and butadiene as monomers to copolymerize to obtain butadiene isoprene rubber, and then using butadiene rubber as base rubber to mix to obtain low temperature resistant compound rubber; then put it into a flexible joint injection molding mold for injection molding . The physical and mechanical properties of the prepared low-temperature-resistant rubber compound have been significantly improved, and it still has good performance in the environment of ‑50 °C. The swing performance of the flexible joint after molding meets the index. The metal parts are positioned by the injection molding die, so that the metal parts are During the molding process, the position is fixed, and the injection molding method is used to precisely control the feeding amount of the flexible joint to ensure the consistency of the product. Through the injection molding method, the production efficiency of the product is increased by 50%. |
