We usually see are shaped into bending rotation of the
spring, spring factory tell you spring winding method is divided into two kinds: (
1)
Cold roll method: spring wire diameter d ≦ adopt method of cold roll winding of 8 mm.
Cold rolled under the springs of the common cold drawn and the heat treatment of high quality carbon spring steel wire in advance, not have commonly after winding quenching treatment, just rolled low temperature tempering to eliminate the internal stress.
(
2)
Hot coil method: spring wire diameter is larger,
d﹥8毫米)
Spring is with hot volume method.
Rolled under the hot spring, after rolled must be quenched, medium temperature tempering, etc.
