Custom Heavy Duty Metal Coil Compression Springs Auto Springs
Description
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.
Folding strengthening process
Pressure spring, is a kind of metal accessories formed by the line
spiral geometry, so his hardening and strengthening operations than
flat hardware accessories (such as stamping parts) to be difficult
Compression spring
Compression spring
In addition, the hardening effect of the transverse section of the
compression spring should be strictly controlled, so as to fully
improve the resistance to fatigue fracture of the decompression
spring after use.
Pressure spring should be generally used: shot peening hardening,
heat treatment hardening two ways,
One: shot peening and hard compression spring processing: to deal
with a batch of pressure springs, Can pressure spring through the
individual belt conveyor to the chamber blasting, blasting in the
city is equipped with a set of parallel stick way, strengthen the
roller to roll at the same time, the pressure spring side rotates
forward, can allow high speed rotation through the way so pill
circulation overvoltage between each coil spring, hit the ring of
metal on the surface, it is the most important parts of pressure
spring stress, shot peening, suspension spring best strengthen the
hand The fatigue life of high stress spring can be increased more
than 4 times after proper shot peening.
