Product size according to customer requirements, can be made into single wave, double wave or multi-wave, rubber body is not limited by the mold. The product is composed of internal and external rubber layer, curtain layer and steel ring tubular rubber parts, after high temperature, high pressure vulcanization molding, and then combined with metal flange or parallel joint loose sleeve.According to the different media used by the rubber material is different, there are natural rubber, nitrile rubber, epdm rubber, neoprene, etc., with high temperature resistance, acid and alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions.
With the continuous development of economy, sometimes non-standard rubber soft joints are needed in special cases, and it is too expensive to re-make the mold or change the mold. Therefore, in order to save costs, people think of winding rubber soft joints to replace the fixed mold vulcanized rubber soft joints。What is the winding rubber soft joint, and what is its production process?Winding rubber soft joint is composed of inner and outer layer of rubber, curtain layer and steel wire ring tubular rubber parts, made by hand, after high temperature, high pressure vulcanization molding and then combined with metal flange or parallel joint loose sleeve.This product makes use of the advantages of rubber such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance to reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature change. Widely used in various pipeline systems.
Production process of wound rubber soft joint: during the production process of rubber soft joint, the inner part is not pure rubber, but with woven net. To make qualified rubber soft joint, the inner rubber layer pipe blank is placed on the work table, the surface of the pipe core is coated with an appropriate amount of isolating agent, and then the inner rubber layer pipe blank is filled with an appropriate amount of air for the core. After the core, arrange, check, whole diameter and store well, send to the next process for winding molding.
According to the production requirements, determine the winding equipment parting piece, mouth shape, winding stroke. Prior to winding the first wire-rubber soft joint, the steel wire is applied in line directions through lead rings, tension assembly, line parting, and line shaping. After that, the line is fastened on the lead pipe of the traction machine with rubber cloth according to the winding direction, and the winding machine is started to make the lead pipe move forward slowly.After the winding stroke is adjusted, install the medium film and introduce the tube billet with the woven protective layer (the surface has been wiped with solvent), then the steel wire rubber soft joint winding can be started. At the beginning of winding, the speed should increase gradually, and when it reaches a certain speed, the film should be introduced into the winding layer at the same time.
When winding, steel wire tension should be uniform, steel wire on the tube billet should be arranged in order, uniform flat, traction device pressure tube should be moderate, should not be too tight, to prevent deformation of the tube billet. When will non-standard rubber soft joints be used? 1) the length differs greatly from the molded rubber soft connection, which is too short or too long. 3) the drilling hole is too different from the standard, especially the hole center distance is too large, the mold can not meet the requirements.
