Abstract

The invention discloses a tensile fixture of a round bar tensile sample. The fixture comprises an upper connector and a lower connector, which are respectively connected with a tester, wherein the fixture also comprises an upper clamp connected with the upper connector; the upper clamp comprises an upper chuck; the clamp also comprises a lower clamp connected with the lower connector; the lower clamp comprises a lower chuck; the fixture also comprises lower bolts which are arranged inside the upper chuck and the lower chuck. By adopting the tensile fixture, the defects of large noise, high power consumption, incapability of mounting an extensometer and the like of the traditional fixture are overcome; meanwhile, the tensile fixture is convenient and fast to replace, and is an accurate, fast and economic clamp system.

Description

technical field [0001] The invention relates to a tensile clamp for a round bar tensile sample. Background technique [0002] Nuclear power manufacturing enterprises use yield strength as an assessment index for raw material acceptance, welding material acceptance, welding process evaluation, product witness, etc., and this assessment index is essential, but in many cases many materials and welding consumables There is no obvious yield. In this way, it is necessary to measure Rp0.2 (prescribed plastic extension strength) as an assessment index. The measurement of Rp0.2 needs to be completed with an extensometer. The existing tensile fixture uses a hydraulic fixture. The extensometer needs to lengthen the tensile standard sample, which causes a waste of material, and in many cases the specification of the material is fixed, and the sample cannot be lengthened at all. At the same time, the hydraulic fixture also has the disadvantages of high power consumption and high noise ...
