Description

Rust-proof high-stability compression spring

Technical Field

The utility model relates to a compression spring technical field specifically is an antirust high stable compression spring.

Background

Compression spring (pressure spring) bears the coil spring to pressure, and the material cross-section that it used is mostly circular, also has rectangle and stranded steel entangle to coil, and the spring is generally the equidistance, and compression spring's shape has: cylindrical, conical, convex and concave, and a small amount of non-circular, etc., there is a certain clearance between the coils of the compression spring, the spring contracts and deforms when subjected to an external load, stores deformation energy, and the compression spring (compression springs) provides a resisting force to the external load pressure. The compression springs are typically wires wound at equal pitch and having a fixed wire diameter. The compression spring utilizes a plurality of open coils to supply a resistive force to an externally applied pressure (e.g., gravity pressing down on the wheel, or the body pressing against a mattress). That is, they push back against the external pressure. The compression springs are typically wires wound at equal pitch and having a fixed wire diameter. In addition, there are conical compression springs, or a combination of conical and linear springs. Depending on the field of application, compression springs may be used to resist pressure and/or store energy. Round wire is the most common compression spring, but there are also compression springs made of square, rectangular and specially shaped wire.

The existing compression spring is affected by the use environment and is easy to rust, meanwhile, if the stress direction is not normal, torsion is easy to occur, and frequent torsion makes the spring material easy to fatigue, so that the spring loses elasticity and the subsequent use is affected.
