Description

Technical Field

[0001] The utility model relates to the technical field of spring steel wire detection, in particular to a spring steel wire elastic force detection device. Background Art

[0002] Spring steel wire is a kind of steel wire used to make springs or steel wire parts. According to the different uses of springs, there are many types of spring steel wires required for making springs, such as spring steel wires for mattress springs with lower requirements, spring steel wires for shock absorbers, spring steel wires for suspension springs, spring steel wires for engine valves, spring steel wires for camera shutters, etc. Although there is no unified standard classification name, the quality requirements of these steel wires are different. Spring steel wires can also be classified according to the manufacturing process, such as raw spring steel wire, lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring steel wire, etc.

[0003] Before making springs, existing spring steel wires need to be tested for elasticity. Generally, spring steel wire elastic force detection devices use a downward pressure method to perform detection. The spring steel wire is first compressed to make it rebound, and then the elastic force is determined by measuring the rebound height. However, this detection method does not perform a tensile test on the spring steel wire, so that the rebound performance of the spring steel wire cannot be determined, and then the elasticity detection of the spring steel wire is not comprehensive enough. In addition, general detection devices cannot detect the spring steel wire at different temperatures. For this reason, we propose a spring steel wire elastic force detection device.
