Standard parts for Japanese pressure spring pin:

Japanese pressure spring pin with standard parts and Japanese pressure spring inner diameter standard parts similar to the spring is based on the inner diameter, customers use rod or pin installation requirements, we strictly control the diameter of a spring. These coil springs can operate independently, although they are usually mounted on a guide bar. When you apply a load to the compression coil spring to make it shorter, the bar acts as a righting spring, allowing it to operate vertically as possible. It will have resistance and try to get back to its original length. Compression spring is an open coil or pressed helical spring, used to resist the axial force generated by compression, compression spring will produce resistance to linear pressure (thrust), in fact, the spring is the most efficient storage of energy.

Network optimization materials:

Commonly used spring materials are:

1. Carbon spring steel

This (such as 65, 70 steel, etc.) has the advantages of cheap price, convenient source of raw materials, the disadvantage is low elastic limit, easy to lose elasticity after repeated deformation, and can not work normally at 130 degrees.

2. Low manganese spring steel

Compared with carbon spring steel, this spring steel (such as 65Mn) has the advantages of better hardenability and higher strength; The disadvantage is easy to crack and hot brittleness after quenching. But because the price is cheap, so the general mechanical often used to manufacture the size of the spring, such as professional butterfly mold spring.

3. Silicon manganese spring steel

The addition of silicon to such steels (e.g. 60Si2Mn) significantly increases the elastic limit and increases the tempering stability, and thus allows tempering at higher temperatures, resulting in good mechanical properties. Has been widely used in industry, generally used in the manufacture of automobile, tractor coil spring and so on.

4, Ming Vanadium steel

The purpose of adding vanadium to such steels (such as 50CrVA) is to refine the structure and improve the strength and toughness of the steel. This material has good milk fatigue and impact resistance, and can work reliably at temperatures from -40 degrees to 210 degrees, but is more expensive. It is often used in demanding situations, such as the spring used in the aero-engine regulation system.=
