OEM 4mm Alloy Steel Helical Coil Powerful Compression Spring For Motorcycle Auto Parts
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.
Finally, Large spring in hot state processing molding then quench-tempering, medium-sized spring in cold state processing molding (raw materials require spheroidization or most spheroidization), and then quench-tempering. Small spring with cold rolled steel strip, cold drawn steel wire and other cold processing molding, low temperature tempering
We sincerely hope to establish extensive and lasting business
relations, and we assure you that we shall do our utmost to
establish friendly business relations between us.
We shall be glad to serve you and give you an enquiry.
