Description of the design of tensile tester fixture

Tension testerThe reason why tensile tests can be performed on different materials is determined by the different size and shape of the tensile machine fixture. The following is a brief introduction to the furniture structure of the tensile tester.

Requirements for fixture structure. The design of the fixture is mainly based on the test standards of the material and the shape and material of the sample (specifically referred to as finished and semi-finished products). The above test standards refer to ISO, ASTM, DIN, GB, BS, JIS, etc., as well as enterprise standards, industry standards, etc. These standards generally have strict regulations on sample preparation and test methods. We can design different fixtures according to the different samples and test methods. For fixtures used for special samples (finished and semi-finished products), fixtures are mainly designed based on the shape and material of the sample.

The test force of the sample (or product) is applied to clamp the sample by clamping the sample. The test force that the clamp can withstand is a very important indicator of the fixture. It determines the size of the fixture structure and the labor intensity of the fixture operation. The sample materials are divided into metal and non-metal, and the shapes are divided into various materials. The test force that the sample can withstand is as small as a few dozen centimeters (such as spandex wire for textiles), to dozens of tons, such as ordinary steel. The domestic electronic universal testing machine has a test force of 1000KN, a level 1 machine, the sample size is as small as gold wire with a diameter of φ0.005mm, and PVC pipe with a diameter of 1.5m, etc. This requires the selection and design of different fixtures according to different test forces and the shape of the sample.
