Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0040] A tensile tester, comprising an annular inner casing 17, a pressurized hydraulic cylinder 14, an oil cylinder chamber 5, an oil storage chamber 16, a pressure detector 18, a displacement detector 3, and two cable end safety lock caps 1, 19. The middle part of the inner casing is hollow, which is used to wear the cable to be tested, and seal the cable inside the casing to ensure safety. The pressurized hydraulic cylinder is installed in the middle of the outer edge of the shell, and the oil storage chamber and the oil cylinder chamber are coaxially installed on both sides of the pressurized hydraulic cylinder, and the adjacent cavities are sealed as required. 1. The pressure oil between the cyl...

Abstract

The invention relates to a tension tester, comprising an inner sleeve shell, a pressurization hydraulic oil cylinder, an oil cylinder chamber, an oil storage chamber, a pressure detector, a displacement detector and two cable-end safety lock nuts of a cable, wherein the central part of the inner sleeve shell is hollow; the pressurization hydraulic oil cylinder is mounted at the central part of outer rim of the shell; the oil storage chamber and the oil cylinder chamber are coaxially installed at two sides of the pressurization hydraulic oil cylinder; a place located between two adjacent chambers is sealed as needed; pressure oil among the pressurization hydraulic oil cylinder, the oil storage chamber and the oil cylinder chamber is used as a power working medium; and the pressure detector and the displacement detector are respectively installed at two sides of the inner sleeve shell and used for detecting changes of pressure and displacement in real time. The tension tester provided by the invention has the advantages of stable performance, advanced technology, a high level of automation, accurate testing precision and limiting and overload protection functions.

Description

technical field [0001] The invention belongs to the field of tensile test of metal and nonmetal, and relates to a tensile tester. Background technique [0002] Along with the development of the national economy, the technical requirements of the tensile testing machine are getting higher and higher. The previous testing machine used a dial to display the force value. The tensile machine of the present invention is operated by a computer, which is convenient and more accurate. The original tensile machine is mechanical. For example, as early as 1880, the United Kingdom produced a lever-weight material testing machine, and in 1908, it produced a universal testing machine loaded with nuts and screws. These testing machines can stretch materials. , compression, bending and torsion tests, but due to the complex structure, bulky, cumbersome operation, only static tests can be performed, so it was eliminated. Eiw industrial robot, tensile machine, tensile testing machine, constant...
