Description

Rubber soft joint hydraulic quick disassembly equipment

technical field

The invention relates to the field of rubber soft joints, in particular to hydraulic quick disassembly equipment for rubber soft joints.

Background technique

Rubber soft joints are also called rubber tube soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, etc., which mainly include rubber tubes and flanges set at both ends of the rubber tubes. , the two ends of the rubber tube are respectively provided with annular clamping edges, and the flange is sleeved on the ends of the rubber tube and limited by the annular clamping edges. The rubber soft joint acts as a flexible connection on the metal pipeline. It is a pipeline joint with high elasticity, high air tightness, medium resistance and weather resistance. It plays an important role in the overall seismic performance of the pipeline and the prevention of pipeline deformation. critical use.

The rubber tube in the rubber soft joint takes advantage of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of rubber, and adopts polyester cord fabric with high strength, strong cold and heat stability, and rubber After compounding, it is vulcanized by high-pressure and high-temperature molds.

Although the rubber tube has elasticity, it also has certain strength and hardness, especially the annular clip edge at its end. In order to ensure the connection firmness of the rubber soft joint, the rubber tube and the flange generally need to be tightly clamped, that is, the flange needs to be tightly socketed on the rubber tube. When the flange is socketed on the rubber tube, the ring clip edge needs to pass through the center hole of the flange first. It is very time-consuming and laborious work to deform and pass through the central hole of the flange, which leads to difficulty in assembling the rubber tube and the flange, high labor intensity for workers, and low work efficiency. In addition, it is also very difficult to disassemble the flange and the rubber tube after assembly. For this reason, the flexible joint with damaged rubber tube is often discarded together with the flanges at both ends, resulting in great waste.
