Description

Technical Field

[0001] This utility model relates to the field of bolt testing technology, and in particular to a device for testing the mechanical properties of bolts of various specifications. Background Technology

[0002] Precise mechanical testing of bolts is a crucial step in evaluating their material properties and reliability. Test indicators include tensile strength, yield strength, and elongation. A tensile testing machine is used to stretch the specimen until it breaks, and the load-displacement curve is recorded. This allows for precise calculation of the material's plastic deformation and load-bearing capacity under stress. Testing the mechanical properties of bolts requires random sampling, breaking the bolts to obtain samples for specimen fabrication. These samples are then broken using a tensile testing machine to obtain the mechanical properties. This testing process damages the bolt threads, rendering them unsellable. Utility Model Content
