Custom Heavy Duty Metal Coil Compression Springs Auto Springs
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.
