At present, the spring steel thread cover more and more people's attention, to a certain extent to improve labor productivity and efficiency, reduce the cost, prompted the spring steel thread cover high-speed development. Steel wire manufacturer specializes in the production of spring steel wire thread sleeve, which introduces the four characteristics of spring steel wire thread sleeve.

I. diamond copper wire of steel wire bushing is reflected in rolling process, making the metal surface layer cold hardening layer depth up to more than 0.1mm, then grain refinement and strengthening, so the mechanical strength and surface hardness are greatly improved, the surface roughness is more than Ra0.8. Therefore, the thread strength of steel wire bushing is higher than that of the overall bushing, and the inner thread of the bushing and the substrate is elastic connection, the force is uniform, and because the size of the bushing section and the force arm are shortened, the bearing capacity of the internal thread of the substrate is increased by about 20~ 40%, and the service life is extended.

Second, the manufacture is simple, the production efficiency is high. The overall thread bushing wall is thin and the thread precision is high. It USES solid bar material through drilling, reaming, boring and cutting thread and other processes, the production cycle is long, the labor intensity is large, the production efficiency is low, the consumption of materials and power is much, and the high precision thread in the lathe system is difficult to achieve, the technical level of workers is higher. And steel wire bushing using diamond wire winding can be completed by ordinary lathe and simple tools, so the processing is simple, and can save 2~3 sets of high precision thread lathe, improve labor production up to 3~5 times.

Three, copper wire bushing is a kind of no cutting process, diamond steel wire winding into thread bushing, only a few excess screw material head excised, strong and material utilization rate up to 95%. Steel bushing small volume, weight diameter, material consumption is only about l / 20 of the same specification bushing.

Iv. Low cost, about 1/3 lower than the overall bushing cost.
