Gas-type tensile testing machine used for rod-shaped metal

Abstract

The invention discloses a gas-type tensile testing machine used for rod-shaped metal. The tensile testing machine comprises a main control housing; the bottom of the main control housing is provided with a support plate structure; the main control housing and the support plate structure are combined to form an integral structure; the bottom of the support plate structure is fixedly provided with a fixing plate; the internal part of the main control housing is provided with a moving space; a spacing hole structure is arranged on the main control housing on one side of the moving space; a sealing column is arranged on the main control housing on one side of the spacing hole structure; the center of one end surface of the sealing column is provided with a main sealing rubber pad. The gas-type tensile testing machine is taken as a technical measuring equipment of known metal mechanical properties; detection effect is achieved via preset of air pressure; when the air pressure is larger than a preset air pressure, further compression is avoided, so that accurate detection is realized using simple equipment at low cost; the gas-type tensile testing machine is relatively low in cost, long in service life, and relatively high in practicality.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a gas-type stretching machine for rod-shaped metals. Background technique [0002] At present, regarding the stretching of rod-shaped metals, high-precision instruments are used to carry out tensile tests. The main function of the tensile test is to measure the maximum deformation force of the object, so as to better understand the mechanics of the metal. Performance, but the general stretching machine is expensive. Although the precision is high, its service life is affected by the precision, which has great limitations.
