Abstract

The invention discloses a curved surface sample tensile property test fixture for testing the tensile property of a curved surface sample. The fixture comprises two pull rods, two pull rod sleeves, a compression plate component, a connecting pin and fastening bolts. The fixture is simple in structure and convenient to use, can be used for testing the tensile property indexes of multiple curved surface samples on the basis of meeting national standard provisions of tests on the tensile property of materials, and can obtain a favorable application effect in actual tests; compared with the prior art, the testing method has the significant property, and is convenient to popularize.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a test fixture for testing the tensile properties of curved surface shape samples. Background technique [0002] Tensile performance test is an important basis for evaluating the quality of materials. Through tensile tests, various properties such as elasticity, strength, and ductility of metal materials can be evaluated. Quality control provides an important means. In practical applications, since the curved surface structure parts have many functions and characteristics such as high rigidity, good force resistance, good stability, and low material consumption, among them, the spherical and cylindrical curved surfaces are more easy to process, so the curved surface structure zero Components are widely used in various fields and industries. [0003] However, for many years, the existing test technology for tensile properties of materials can only test the tensile properties of straight ...
