[0005] The purpose of the present invention is to provide a high-elastic 4Al-22V wire processing technology for spectacle frames, which overcomes the deficiencies in the prior art and solves the problem that the existing alloy wires are either too elastic or too soft, which causes the glasses to slip easily when worn. Or partial hardness, which oppresses the skin when worn, causing the wearer to feel uncomfortable and technical problems

Embodiment 1
[0024] A kind of highly elastic 4Al-22V wire material processing technology for spectacle frame, comprises the following steps:
[0025] S1. Crush titanium sponge, then sieve, and finally dry to obtain granular titanium materials. Separately crush or cut, clean, and dry the master alloy of each alloy element to obtain master alloy particles, which are weighed according to the proportion of titanium alloy components. Taking intermediate alloy particles and granular titanium materials and mixing them to prepare alloy mixtures; the particle sizes of the granular titanium materials and the intermediate alloy mixtures are both less than 200 mesh;
[0026] S2, pressing the alloy mixture into an electrode;
[0027] S3. The electrode obtained in S2 is smelted once in a vacuum consumable electric arc furnace, then cast into an ingot, and finally smelted twice, then peeled, forged, rolled, and finally drawn into a wire billet; the wire billet needs Pre-treatment: pickling, repairing, a...
Embodiment 2
[0031] After many attempts, it was found that when the wire is drawn in multiple passes, the size of the wire drawing is φ9-10mm, φ5-6mm, and φ3-4mm, respectively, and in this way, the inside of the drawn wire shows a fibrous distribution. , and the fibrous distribution is the most stable when the size is less than φ4mm after the last wire drawing.
Embodiment 3
[0033] The semi-finished silk blank is cold drawn with a deformation of 20-25%; when the finished product is cold-drawn with a deformation of 32-35% under liquid nitrogen cooling, the elasticity of the wire is the most moderate, and the eye frame is very good. The elasticity will not be too tight on the facial skin, nor will it be too soft to slip off easily.

Abstract
The invention belongs to the technical field of titanium alloy wire processing, and particularly relates to a processing technology of a high-elasticity 4Al-22V wire for a spectacle frame, a wire blank processed by a traditional method is put in a vacuum constant temperature environment for multi-pass wire drawing, the wire drawing rate is 15mm/min, the constant temperature is 780 +/-20 DEG C, and the finish rolling temperature is greater than or equal to 750 DEG C; in the wire drawing process, the wire drawing rate is kept constant, so that the surface of the wire is prevented from being scalped or scratched, abrasive paper is adopted for surface coping, a glass lubricant is sprayed, and a semi-finished wire blank is obtained; the 4Al-22V wire material for the spectacle frame is obtained by carrying out cold drawing on a semi-finished wire blank at room temperature at the deformation of 0-30%, carrying out finished product cold drawing at the deformation of 10-40% under liquid nitrogen cooling, finally carrying out high-temperature calcination for 10-20 minutes, and naturally cooling to normal temperature. And the technical problems that the glasses are easy to slip off when being worn, or are slightly hard, the skin is pressed when the glasses are worn, and a wearer feels uncomfortable are solved.
Description
technical field [0001] The invention belongs to the technical field of titanium alloy wire processing, and in particular relates to a high-elasticity 4Al-22V wire processing technology for spectacle frames. Background technique [0002] Titanium and titanium alloys are known as "three-generation metals" and "third-generation metals" because of their outstanding advantages such as high specific strength and corrosion resistance. It is an indispensable key material and has important strategic significance for national defense, national economic construction and social development. [0003] β titanium alloy is the most active titanium alloy in the research and development of titanium alloy in recent years. The outstanding advantage of this alloy is that it has good cold formability in solid solution state. Since Rem Cru Titan developed the first β-titanium alloy (Ti~3Al~13V~11Cr) in 1952, due to the many excellent properties of this type of titanium alloy, titanium researcher...
