A simple understanding of the accessories of universal testing machines

Attached pairUniversal testing machineIt is a relatively important component, and its importance is self-evident. It is for ordinary metal and non-metallic specimens,The jaws of the fixture are in direct contact with the sample. Generally, high-quality alloy structural steel is used, alloy high-carbon steel (or low-carbon alloy steel), cold-work mold steel, etc., and their strength and wear resistance are added after appropriate heat treatment processes (quenching, carburizing and quenching, etc.)..Sometimes special steel is also installed in the jaws,Or spray gold and steel sand on the surface of the jaws, etc..For some clamps with small experimental strength, the surface in which they come into contact with the sample is used to use soft rubber leather. (For example: the clamping surface of plastic films, fiber wires and other samples.) The clamp uses high-quality medium-carbon steel and alloy structural steel, and its mechanical functions are added through appropriate heat treatment processes. Sometimes, non-ferrous metals such as aluminum alloys and special metals are used in order to reduce the weight. Sometimes forged structures (cast steel,Cast aluminum, etc.).
