China Factory Manufacturer Customized OEM High Elastic Metal Compression Spring
Compression spring is a kind of hardware fittings with spiral geometric shape formed by wire, so it is more difficult to harden and strengthen the work than the plane hardware fittings (such as stamping parts). In addition, it is also necessary to strictly control the hardening effect of the cross section of the compression spring, so as to fully control the fatigue fracture resistance of the decompression spring after use.
Compression spring is under axial pressure of the spiral spring, can withstand the pressure, both ends can be open or closed or round flat or smooth, materials used in the cross section is round more, it is also useful for rectangular and multi-strand steel rolled a travelling, springs have a pitch and defect, such as the shape of the compression spring are: cylindrical, conical, convex and concave, and a small amount of noncircular and the variation of various end, All products need to be shaped in accordance with the design, etc. There is a certain gap between the rings of the pressure spring and the rings. When subjected to external load, the spring contracts and deforms, and the deformation energy is stored.
Design and production
1. Choose spring material according to the standard according to the actual product demand.
2. According to the product force value and compression stroke, fatigue and other requirements, determine the inner and outer diameter of the pressure spring, the effective number of turns, and the value range of the line diameter.
3. Substitute relevant parameters into the design parameter formula..
4. It is also reasonable and feasible to design and produce spring manufacturers.
