1) Variable mold nitrogen spring diameter, variable pitch and variable wire diameter (three variants) Die nitrogen spring suspension to achieve a non moldability processing. Since the development of precision molds nitrogen spring, we have been using a tapered steel bar in CNC lathe processing wound, but finished the north and prices are not ideal. The state will now heated by coiling machine, roll speed and control pullout force to obtain the desired shape of a cone, and quenching process heat.
2) stable mold hollow nitrogen spring pole low-carbon boron steel, rolled welded shape.
3) the torsion bar 45 with high purity steel, obtained by high-frequency quenching high surface hardness and a larger residual compressive stress, thereby increasing the fatigue life and resistance to relaxation capability.
4) electronic products are widely used in the lens mold nitrogen spring basically automatic punching and bending forming. At present, the development of composite bonding techniques.
5) The main valve spring nitrogen mold developing multi-stage shot peening and liquid nitriding process, to improve the surface residual compressive stress, improve fatigue life.
