Basic requirements for threaded retractable rubber connections

After being cut and cleaned, the threaded retractable rubber joint is rolled up and sent to the vulcanization point. In addition, coolant is used to cool the induction coils used in the heating process. Some of the coolant will be used in the kneading process. Here, a large force is applied to the kneading pulley to prevent porosity in the vulcanized area; however, the higher kneading force applied will result in increased burrs. Thus, specially designed threaded retractable rubber connections are used to remove burrs from the inside and outside of the tube.
Vulcanized cracks, which may occur in flat areas at low strength joints, cannot be detected by conventional methods and may therefore lack reliability in some demanding car applications. With a threaded retractable rubber flexible connection or welders chisel to sort out the shortcomings, such as shortcomings eradicated after the weld appearance molding can not meet the requirements of the specification, it is necessary to fill the weld from scratch. It is necessary to take into account the orientation of the arc initiation and arc extinguishing when welding; the weld should be polished from the beginning after the completion of welding, so that the transition is smooth. The necessary finishing should be done before patch welding, and it is necessary to take into account the position of arc initiation and arc extinguishing when patch welding; after the completion of patch welding, the weld should be polished and finished from the beginning, so that the transition is smooth. Use the threaded retractable rubber flexible connection or welders chisel to polish the shortcomings so that the weld reaches the specification. Patch welding should be carried out when necessary. Patch welding before the necessary finishing, patch welding is necessary to take into account the location of the arc and arc extinguishing; patch welding should be completed from the beginning to polish the finishing weld, so that the transition is smooth. Use the threaded retractable rubber flexible connection or file to file and grind the bite edge shortcomings, the minor bite edge, such as shortcomings after eradication, and reach the smooth transition and meet the requirements of the specification is considered qualified, the deeper bite edge, it should be repaired after grinding for welding. Patch welding should pay attention to the arc and arc extinguishing, slightly, fill the bitten edge pit. Patch welding after the weld still need to be polished according to the rules, and oil smooth transition to the base material.
In the case of the threaded retractable rubber joint, the flat threaded retractable rubber joint is formed first, and then the outer structure is made into a round tube. Once formed, it is necessary to vulcanize the seam of the tube together. This weld largely affects the formability of the part. Therefore, it is important to select the appropriate vulcanization technique to obtain a vulcanization profile that meets the stringent testing requirements of the manufacturing industry. Typical of most solid phase forgings is that high frequency vulcanized joints are not easily and reliably tested using traditional non-destructive techniques.
