High-low temperature tension tester

Abstract

The invention relates to the technical field of tension testing equipment, in particular to a high-low temperature tension tester, which comprises a temperature change box, an upper pull rod arrangedin the temperature change box, a lower pull rod movably arranged in the temperature change box in a penetrating mode and a sealing ring. The temperature change box is provided with a through hole, thelower pull rod enters the temperature change box through the through hole, the sealing ring is used for sealing a gap between the lower pull rod and the through hole, and a heating device is arrangedin the lower pull rod. The invention discloses the high-low temperature tension tester, the sealing ring is arranged between the lower pull rod and the temperature change box, the lower pull rod cansmoothly penetrate through the temperature change box, meanwhile, relative sealing of the temperature change box is guaranteed, the heating device is arranged in the lower pull rod, the temperature ofthe lower pull rod can be increased, frost condensed on the surface of the lower pull rod can be dissolved, the pull rod is prevented from being fixed to a box body, and accurate tension testing canbe guaranteed at high temperature and low temperature.

Description

technical field [0001] The invention relates to the technical field of tensile testing equipment, in particular to a high and low temperature tensile testing machine. Background technique [0002] Tensile testing machine is a mechanical force testing machine used for static load, tensile, compression, bending, shearing, peeling and other mechanical performance tests on materials. It is suitable for plastic sheets, pipes, profiled materials, plastic films and rubber. Various physical and mechanical performance tests of materials such as wires and cables are used for material development, and are indispensable testing equipment for physical property tests, teaching research, quality control, etc. Yuanfeng tensile machine fixtures are an important part of the instrument, and different materials require different Fixtures are also an important factor in whether the test can be carried out smoothly and the accuracy of the test results. [0003] The impact of temperature changes ...

AI Technical Summary

Problems solved by technology

[0003] The impact of temperature changes on the test piece is extremely serious. Therefore, the high and low temperature tensile testing machine is an indispensable equipment for detecting the influence of temperature, but the existing high and low temperature tensile testing machines are prone to freeze the tie rod at low temperature. Due to the situation, the pull rod and the box are fixed together, and the pull data test cannot be performed, so a technical solution to solve the above technical problems is urgently needed
