A gas-type stretching machine for rod-shaped metal

Abstract

The invention discloses a gas type stretcher for rod-shaped metal. The stretcher comprises a main control shell, a supporting plate structure integrated with the main control shell is arranged at thebottom of the main control shell, a fixed plate is fixed to the bottom of the supporting plate structure, a movable space is formed in the main control shell, a limiting hole structure is formed in the side, located in the movable space, of the main control shell, a sealing column is arranged in the side, located in the limiting hole structure, of the main control shell, and a main sealing rubberpad is installed in the center of one end surface of the sealing column. The stretcher is used as technical detection equipment for known metal mechanical properties, a preset air pressure plays a detection role, when the air pressure is greater than the preset air pressure, further compression is avoided, clear detection is realized on the basis of simple equipment and low cost, the using cost islower, the service life is longer and the practicality is higher.

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. Contents of the invention [0003] The object of the present invention is to provide a gas-type stretching machine for rod-shaped metals, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A gas-type stretching ma...
