A high-throughput micro-specimen tensile testing device based on additive manufacturing

Abstract

The application provides a high-throughput micro sample tensile test device based on additive manufacturing, belonging to the technical field of material mechanical property testing, and is used for sequentially performing tensile tests on samples of a test module of additive manufacturing. The device comprises a mounting table, a guide assembly, a tensile clamp and a data acquisition module. The guide assembly provides horizontal guide limiting for the test module. The upper clamp head and the lower clamp head of the tensile clamp are respectively provided with an upper clamping cavity and a lower clamping cavity matched with a bearing convex structure. The upper clamp head is driven by a tensile loading device to complete tensile and reset. The data acquisition module acquires test data. After the sample is broken, the upper clamp head is reset, the complete sample pushes the upper half of the broken sample out of the clamping range through a pushing convex structure, and the lower half is moved out with the test module, so that synchronous feeding and discharging are realized. The device realizes continuous tensile test of the sample, improves the comparability and repeatability of test results, and improves the test efficiency of the tensile test.
