Base on the actual meaning of damping spring cable diameter from very small to quite large, all can be said to have this effect.
Spring manufacturer to introduce damping spring cannot tell size, there are small, there is also a very large, such as railway, large and medium-sized mechanical equipment on the whole is basically the shock absorption spring, spring also some means of miniature circuit, in accordance with the main application can also be called damping spring.
But the traditional understanding on known as small as the
compression spring, and cable diameter in 3.
Above 0 in traditional suspension springs, in general, a spring winding way points are two kinds of cold rolled and hot roll laws.
1, cold volume method: selection of spring wire diameter d 8 mm or less cold winding volume method.
Hot springs pour machine under common cold drawn and after conditioning treatment in advance of high quality carbon spring steel wire, has generally don't conduct heat treatment after pouring machine, only need to cryogenic tempering to remove wire machine thermal stress.
2, hot roll method: spring wire diameter is very big,
d>
8mm)
Spring is using hot coil winding.
Under the hot rolling of the spring, lay in it is important to carry out after heat treatment, such as medium temperature tempering to solve.
When an application does not need to heat treatment after forming, temper to solve the raw materials of manufacturing spring, its processing technology process for the narrow spiral spring: on both sides of the production, the stress relieving, cutting, (
Blasting derusting)
、(
The school the whole)
、(
The stress relieving)
, standing, or crush solve, packaging, testing, surface anticorrosion.
