Spring manufacturers tell you in the spring of idea

1.Without supporting ring spring and spring wire diameter interloper spring should not be welding head, but end wire should not have obvious loose, deburring.Would all the welding head more strands of spring, the weld length should be less than three times the cable diameter (the longest not greater than 10 mm).Heating length should be less than a circle, should be polished smooth after welding, gas welding when the welding parts should be partial annealing at low temperature.

2 according to the product, bearing ring can use cold and hot and the two methods.Using thermal and spring are not allowed to be heated to spark or white, silicon manganese steel temperature is not higher than 850 ℃.With effective support circle should be effective contact, clearance shall not exceed 10% of the nominal gap between circle.

3, many strands of spring can be adjusted by the lead decision, winding line distance can make the necessary adjustments.Screw pitch desirable 3 ~ 14 times wire diameter, but generally take 8 ~ 13 times is preferred.The spring force and free height, and end ring, outside diameter and the steel wire performance is closely related, and can be adjusted through changing one or a few.
