Spring is now essential items in production and life, has a lot of enterprises to the market, production vigorously, believes that many people will be asked about how to improve the quality of the spring? In fact can be roughly divided into: factors which influence the production of spring drawing process, production organization and equipment, the following respectively introduce for everybody.
1, how to optimize the drawing process, the equipment number of drum under certain conditions, to keep the total compression rate unchanged at this moment, the decrease of the appropriate part of the compression ratio, appropriate to increase the number drawing, especially reduce the last part 1 original compression ratio, may change the state of the stress distribution inside the wire, the tensile strength reduced constantly, plasticity index rising, product qualified rate will be greatly improved.
2, in the process of drawing steel
