Problems solved by technology
[0002] High-pressure rubber hose is a very important pipeline connector. Improper selection of crimping amount and crimping speed when assembling the hose and joint, or unreasonable selection of structure, material, and size of the joint can cause the hose and joint to be too tight or too loose. , causing early damage at the joint
Therefore, the distortion test about the high-pressure rubber hose is very important, but the problem is that the distortion test of the prior art is very simple, and the distortion of the actual working condition is far more complicated than that simulated by the test device of the prior art, such as when the metal joint When the torsional force of the part and the rubber hose part is not uniform, the twisting result cannot be expressed, and the same is a metal pipe joint, and the torsional force suffered by the front part and the middle part with the outer hexagonal part is also different. The twisting test device of the prior art The authenticity of the test results cannot be guaranteed
