Flexible metal tube static bending test machine

Abstract

The invention relates to a flexible metal tube static bending test machine, which comprises a platform, a linear oil cylinder and a pump station, and is characterized in that: the platform is provided with grooves which form a shape like the Chinese character 'mi', the side edge of the platform is provided with a fixed support plate corresponding to the grooves which form a shape like the Chinese character 'mi, the grooves which form a shape like the Chinese character 'mi and are parallel to the fixed support plate are connected with a universal tool on two ends of a test piece through a movement mechanism, the lower side of the test piece is provided with an L-shaped support plate with a position fixing groove, a solid body with the cross section of a circular crown shape is arranged between a vertical plate of the L-shaped plate and the test piece, a circular crown of the solid body is pushed against the middle position of an axis of the test piece, a front baffle plate which is limited by the position fixing groove is arranged on an L-shaped support plate horizontal plate on the other side of the test piece to correspond to the solid body, the lower side of the L-shaped support plate horizontal plate is also connected with the grooves which form a shape like the Chinese character 'mi and are vertical to the fixed support plate through the movement mechanism, the other side of the vertical plate of the L-shaped support plate corresponding to the solid body is connected with the large-displacement linear oil cylinder which is connected with the pump station. The test machine is provided with protection facilities such as over-temperature alarm, over-displacement alarm and the like. The test machine is provided with a control cabinet, a visible operation interface, a hand operation area and an automatic operation area, so both the hand operation and the automatic operation can be realized.

Description

technical field [0001] The invention belongs to the technical field of measuring physical parameters of products, in particular to a test device for static bending of metal hoses. Background technique [0002] At present, there is no test item for static bending in the domestic metal hose standard, and there is no test method for static bending. According to the international standard and the metal hose standard that will be revised in China, the test of the metal hose is clearly stipulated. But at present, there is no special testing machine suitable for the static bending test of metal hoses in China. The purpose of the present invention is to develop a test device, which can realize the static bending test of the metal hose according to the international standard, and meet the product testing requirements. Contents of the invention [0003] The object of the present invention is to provide a metal hose static bending testing machine for performing static bending detect...
