1, cold rolling method: spring wire diameter d = 8mm by cold roll winding method. Cold rolled spring cold and the commonly used high quality carbon spring steel wire heat treatment in advance, after winding general no longer quenching by low temperature tempering to eliminate internal stress when winding.
Method: 2, coil spring wire diameter (d>8mm) with spring coil winding method. In the spring of hot rolled down system, must be carried out after quenching, tempering treatment etc.
When the spring is made of the material without quenching and tempering after forming, the process is as follows:
Helical compression spring: rolling, stress relief annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing processing, testing, surface treatment, packaging.
Helical tensile springs: coiling, de stress annealing, hook ring fabrication, (cut off), stress relieving annealing, standing treatment, inspection, surface corrosion treatment, packaging.
Spiral torsion spring: roll system, stress annealing, torsion arm manufacture, tail cutting, stress relieving annealing, standing treatment, inspection, surface anticorrosion treatment and packing.
The spiral stretch and torsion springs described above are manufactured by winding the hook or torsion arm at each end of the coil. In recent years, many manufacturers at home and abroad have produced and used computer forming machine or special forming machine. The shape of spring body and tail can be finished once on the forming machine, and the process of machining hook ring or twist arm is omitted.
When the material needs to be quenched and tempered after forming, the main difference with the process is quenching and tempering after forming, and sometimes the end of spring needs normalizing treatment.
The process with brackets is a non - fixed process, whether or not it depends on the performance requirements of the spring.
