Application of extension spring in practice

发布时间:2020-6-4 11:29:50    浏览:24

Spring is a kind of mechanical part which uses elasticity to work. The parts made of elastic materials deform under the action of external force, and return to the original state after removing the external force. It is also called "spring". Generally made of spring steel. The types of spring are complex and diverse, according to the shape, mainly including spiral spring, scroll spring, plate spring, etc.


Let"s introduce the main role of the tension spring in our practice. The tension spring is a coil spring that bears the axial tension. In the case of no load, the tension spring is generally tight without clearance between the rings. We can see it everywhere in our life. Here is an introduction to umbrella spring:


Umbrella spring is the general designation of tension spring, torsion spring and pressure spring used in umbrella. It is widely used in umbrella. Different springs play different mechanical roles in umbrella. Spring accessories are an important part of the umbrella. The common ones are the middle bar support spring, Z-shaped positioning spring, umbrella frame pressure spring, umbrella closing spring, automatic opening and closing tension spring, etc.


Umbrella spring is mainly made of carbon steel wire. According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high quality carbon steel (lower phosphorus and sulfur content), high quality steel (lower phosphorus and sulfur content) and super quality steel. Umbrella spring is generally made of high-quality carbon steel wire, which has strong elasticity, stable quality and higher fatigue resistance compared with other materials. Mainly in terms of price, it"s a little cheaper.


The function of umbrella spring: the umbrella frame spring mainly supports the umbrella bone and umbrella frame, and positions the plastic sleeve and the bow piece so that the umbrella cloth on the surface of the umbrella will not be overturned when it is opened too much, making the whole umbrella stronger in use, and automatically adjusting the opening distance of the umbrella.
