Embodiment Construction

[0021] All the features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0022] Such as figure 2 As shown, the stretching rod 1 in the present invention is L-shaped. One end of the stretching rod 1 is a stretching end and one end is a fixed end. The stretching end is provided with a stretching hole 11 for stretching. A screw hole 12 for fixing the pressure block 6 is provided; a piece is cut out on the side of the tensile end near the fixed end to form a clamping surface 15. A positioning pin 13 is provided on the clamping surface 15 and the positioning pin 13 is a dovetail On the fixed end of the stretching rod 1, a row of fixing holes 14 is provided for fixing the stretching rod cover 2.

[0023] Such as figure 1 As shown, the two stretch rod sleeves 2 are connected together by the connecting pin 3, the fixed end of the stretch rod 1 is inserted into the stret...

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 clamps, in particular to a test clamp for testing the tensile performance of a curved surface profile sample. Background technique [0002] Tensile performance test is an important basis for evaluating the quality of materials. Through tensile test, various properties such as elasticity, strength and ductility of metal materials can be evaluated, which can be used for material inspection, development, improvement, potential utilization, failure analysis, reasonable design and Quality control provides an important means. In practical applications, the curved surface structure parts have multiple functions and characteristics such as high rigidity, good stress resistance, good stability, and low material consumption. Among them, spherical and cylindrical curved surfaces are more easily processed. Therefore, the curved surface structure is zero. Components are widely used in various fields and industries. [0003] However,...
