Abstract

A metal soft tube flexural oscillations tester for conducting life test is provided, which comprises a stander, a control cabinet, an electric control unit and a displaying unit. The technical points are that: a transmission oil cylinder, a rotating axle and a transmission arm are arranged in the stander, which are connected with an arm swinging link gear to compose the actuating unit of the equipment. and the hydraulic pressure machine set drive motor power structure drives the equipment to movement swinging arm; the two ends of the metal soft tube are installed on a fixing pressing base and a dynamic displacement compensation mechanism, and the metal soft tube movement trail is adjusted by an arc limiting structure; one end of the metal soft tube is connected fixedly with the arc limiting structure to realize bending and double-direction swinging function. Through an electric control unit, a starting dynamo, the alternate invariable displacement structure composed of an eccenter, a connecting bar, a linear guide and a movement end connected with base is driven by a reducer driven by electric engine, which makes the metal soft tube fixed on the connecting base of the moving end realize the curvature movement of invariable displacement.

Description

technical field [0001] The invention belongs to the technical field of measuring physical parameters of products, in particular to a metal hose bending and swing testing machine for performing reliability and life tests on metal hoses. Background technique [0002] As we all know, metal hoses are mainly used in electric power, metallurgy, petrochemical, aerospace, aviation, automation and other fields. The quality of the metal hose will directly affect the performance and reliability of the entire system. Therefore, it is an important means to test the product quality and judge the quality of the metal hose to conduct reliability life and performance tests. [0003] The reliability life test of the metal hose, specifically, is to select the bending or swinging form and the dynamic bending radius according to the nominal diameter of the product. In the past, the test device had simple structure and single function, and had problems such as inaccurate and unstable positioning...
