Problems solved by technology

Among them, the pulse test is a fatigue test. It simulates the working state of the hose assembly to verify the service life of the hose assembly, that is, whether the number of pulses meets the standard requirements. The test time span is large, resulting in a long test cycle. Moreover, the test results are uncontrollable, which seriously wastes laboratory resources and virtually increases production costs.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like figure 1 As shown, the combination of the rubber hose 3 and the joint is collectively called the rubber hose assembly, including the core 1 , the sleeve 2 and the rubber hose 3 . The rubber hose 3 of the rubber hose assembly is divided into steel wire braided rubber hose and non-steel wire braided rubber hose. The rubber hose 3 used in the rubber hose assembly with different usage requirements is different, and each has its own testing standards, and this pre-testing method can be used for pre-testing. . The two indicators for judging the connection quality of the rubber hose assembly are the sealing performance of the assembly and the pull-out strength of the assembly. Due to the rubber elasticity of the inner rubber, it can fill the gap between the core 1 and the inner rubber to form a seal when crimping, and the inner teeth of the sleev...

Abstract

The invention discloses a method used for detecting matching property of joints with rubber tubes of rubber tube assemblies. The method can be used for detecting matching properties of combination and withhold outer diameter of the rubber tubes with the joints rapidly, saving valuable pulse experiment time, and providing the best joints and size diameter information of each rubber tube type. And in addition, the method is helpful in selecting matching joints and rubber tubes of rubber tube manufacturers and assembly manufacturers, and is useful in the aspect of customer service. The method can be used for preferable stimulation of experiment conditions of pulse performance experiments, accurate is high, operation is simple, few steps are needed, detection time is short, and success rate of pulse performance experiments is increased greatly.

Description

technical field [0001] The invention relates to a matching detection method for a joint of a rubber hose assembly and a rubber hose. Background technique [0002] Hose assembly is an auxiliary device commonly used in hydraulic systems. It is made of high-pressure steel wire braided or wound rubber hose and steel joints crimped by special equipment, and is used to connect various hydraulic components in the hydraulic system. structured as figure 1 As shown, in actual work, failure forms such as hose blasting, hose trachoma leakage, hose and joint pull-out, internal connection breakage, and initial leakage of hose assembly buckle often occur, causing host and system failures, and even personal injuries. vicious accident. [0003] Existing rubber hose assembly inspection methods mainly include pressure test, burst test and pulse test. Among them, the pulse test is a fatigue test. It simulates the working state of the hose assembly to verify the service life of the hose asse...
