Method for manufacturing stainless steel wire for spectacle frame

Abstract

The invention discloses a method for manufacturing the stainless steel wire for a spectacle frame, comprising the following steps: (1) treating the skin film; (2) drying; (3) drawing for the first time and carrying out bright annealing on line for the first time, wherein the area-reduction rate during drawing for the first time is 40-60%, the temperature of carrying out bright annealing on line for the first time is 1,000-1,100 DEG C, and the speed is 3-9m / min; (4) drawing for the second time and carrying out bright annealing on line for the second time, wherein the area-reduction rate during drawing for the second time is 40-60%, the temperature of carrying out bright annealing on line for the second time is 1,000-1,100 DEG C, and the speed is 5-12m / min; and (5) drawing for the third time and carrying out bright annealing on line for the third time, wherein the area-reduction rate during drawing for the third time is 45-75%, the temperature of carrying out bright annealing on line for the third time is 1,000-1,100 DEG C, and the speed is 5-12m / min. The stainless steel wire manufactured by the method has a bright surface, is free from the surface defect, has high tensile strength temperature and good extensibility and has the following mechanical properties: the yield strength of 300-400N / mm<2>, the tensile strength of 550-650N / mm<2> or higher, the elongation of 50-60% and the hardness value (HV) of 200-300.

Description

technical field [0001] The invention relates to a manufacturing method of stainless steel wire, in particular to a manufacturing method of stainless steel wire for spectacle frames. Background technique [0002] In the past, the material of spectacle frames was generally copper alloy, among which cupronickel was the most common material, but common cupronickel was easy to corrode and deform, and nickel cupronickel was also used as spectacle frame material, and its corrosion resistance was better than that of common cupronickel. In addition, there is also a nickel alloy spectacle frame material, which has good corrosion resistance and is not easy to deform, but its disadvantages are high hardness, heavy weight, and difficult adjustment, which makes people feel uncomfortable when worn. Compared with the above materials, stainless steel is a safe, lightweight, durable and comfortable spectacle frame material, which has good corrosion resistance, ductility and processing perform...
