Description

Device with spring steel wire fatigue life test structure

Technical Field

The invention relates to a device with a spring steel wire fatigue life testing structure.

Background

A spring is a mechanical part that works by elasticity. The part made of elastic material deforms under the action of external force and restores to the original shape after the external force is removed. Also used as a "spring". Typically made of spring steel. The types of springs are complicated and various, and mainly include spiral springs, volute springs, plate springs, special-shaped springs and the like according to the shapes. Most of the current spiral springs are made of spring steel wires wound into a spiral shape. In order to increase the spring strength, the steel wire is heat treated. Most of the prior spiral springs adopt a spring steel wire spiral winding support. Most springs have high working strength and therefore have high requirements on service life. In order to ensure quality, the steel wire needs to be subjected to a fatigue strength test.

After the spring steel wire is made into a spring, the spring steel wire has certain influence on materials, so that the fatigue strength is tested, and the detection of a formed spring sample is recommended. In some large special equipment, because the weight is heavy, the used spring and cabinet lattice are also large, which results in heavy weight. The weight of these springs is measured in tons. When the spring is produced and processed, the spring is generally in a transverse lying state after surface treatment. In design, the fatigue strength of the spring is a high technical index, so that after production is finished, a fatigue test is required. At the moment, the transportation and the carrying are needed, the manual overturning is inconvenient, and no proper equipment is available for processing at present.
