Gas type tensile testing machine for rod metal

Abstract

The invention discloses a gas type tensile testing machine for rod metal. The gas type tensile testing machine comprises a main control shell body, wherein a supporting plate structure of an integrated structure with the main control shell body is arranged at the bottom of the main control shell body, a fixed plate is fixed to the bottom of the supporting plate structure, a movement space is arranged in the main control shell body, a limiting hole structure is arranged on the main control shell body and on one side of the movement space, a sealing column is arranged on the main control shell body and on one side of the limiting hole structure, and a main sealing pad is arranged in the center of one end face of the sealing column. The gas type tensile testing machine disclosed by the invention can be used as technical detection equipment of known metal mechanical properties; by means of presetting air pressure, a detection effect is achieved; when air pressure is larger than preset airpressure, a further compression effect is avoided; thus, an accurate detection effect can be achieved under the premise that equipment is simple and cost is low; furthermore, the gas type tensile testing machine has the advantages of lower use cost, higher long service life and stronger high practicability.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a gas-type tensile testing 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.
