"Industrial Application Field" The present invention relates to a method for manufacturing eyeglass frames using a Ti core material, in which the core material is coated with a sheath material that has good brazing and plating properties, and this sheath material is used to braze the eyeglass frame member. By using it for attaching and as a base for plating treatment,
The purpose is to manufacture eyeglass frames that have excellent brazing strength and plating strength while using a Ti core material. ``Conventional technology'' Ti material is a material with excellent corrosion resistance and is also lightweight, so in recent years it has been attracting attention as a material for the frames of high-end sunglasses and other glasses. However, since Ti material has the disadvantage of poor brazing and plating properties, eyeglass frames made of Ti material have not yet been put into practical use. Conventionally, in order to eliminate the above-mentioned drawbacks and manufacture eyeglass frames using Ti material, Ti for eyeglass frames is made by cradling a Cu alloy onto the surface of a Ti core material.
A baseline material was proposed. ``Problems to be solved by the invention'' In this type of Ti-based wire material, the Cu alloy is removed by etching after brazing, which is conventionally impractical due to the processing surface. The idea is to use hot Ti material for eyeglass frames. However, in the case of the above-mentioned Ti-based wire material, a very brittle intermetallic compound is generated between the Ti and Cu alloy during brazing.
It had the disadvantage of low brazing strength. Furthermore, there has been a known technology for manufacturing eyeglass frames using a wire rod in which a Ti core material is clad with a sheath material made of an Au alloy or an Ag alloy, but this method is easily damaged during brazing, and the sheath material is easily damaged during brazing. Because the material has good thermal conductivity, it is somewhat difficult to braze, and if excess solder adheres to the brazed part, it becomes difficult to remove the excess solder without damaging the main body, making it difficult to use glasses frames. There was a problem that seriously damaged the appearance. "Purpose of the Invention" The present invention was made in view of the above circumstances, and an object thereof is to provide a method of manufacturing an eyeglass frame having excellent brazing strength and plating strength while using a Ti-based core material. . “Means for Solving the Problems” In order to solve the above problems, the present invention
A core material made of (titanium) or Ti-based alloy is covered with a sheath material made of Ni (nickel) or Ni-based alloy,
Extrusion processing is performed to form spectacle frame members such as a rim portion, a temple portion, a bridge portion, etc., the spectacle frame members are then brazed to assemble the spectacle frame, and then the spectacle frame is subjected to a plating process. . "Example" The drawing shows the cross-sectional structure of an eyeglass frame manufactured by carrying out an example of the present invention.
Ni is placed on the outside of the cylindrical core material 1 made of Ti-based alloy.
Alternatively, an eyeglass frame is formed by cladding the sheath material 2 made of a Ni-based alloy. Next, a case will be described in which a spectacle frame having the above structure is manufactured by carrying out an embodiment of the present invention. To form the eyeglass frame, first, Ni or Ni is placed on the outside of the core material made of Ti or Ti-based alloy.
A composite material is formed by covering with a sheath material made of a base alloy. The Ti-based alloy used here preferably contains 90% or more of Ti. The reason for this is that if the Ti content is less than 90%, the plastic workability of the Ti-based alloy deteriorates, and the added components increase the specific gravity, impairing the lightweight property. In addition, the component elements added to Ti to obtain a Ti-based alloy include Al (aluminum), Mn (manganese), Fe (iron), Cu (copper),
One or two of the following component elements are useful: Mo (molybdenum), Cr (chromium), V (vanadium), W (tungsten), and C (carbon). Make the total amount less than 10%. At this time, Ti or Ti-based alloy usually contains H 2 gas and O 2 gas. Furthermore, the above
The Ni-based alloy preferably contains 80% or more of Ni. In addition, the component elements added to Ni to obtain a Ni-based alloy include Cr, Cu, Fe, and Ag.
(silver), Si (silicon), S (sulfur), Pb (lead), Pt (
One or more of the following component elements are useful: platinum), Au (gold), Sn (tin), Co (cobalt), rare earth elements, Mo, Al, Nb (niobium), and Ti. If multiple types of these are added, the total amount
Make it smaller than 20%. Next, the composite material is extruded to bond the core material 1 and the sheath material 2 together, and wire-drawn to form each eyeglass frame member such as a rim portion, a temple portion, and a bridge portion. Here, the clad ratio is
When the total volume is 1, it is desirable that the volume ratio of Ti or Ti-based alloy is 0.7 to 0.99. The reason for this is that if the cladding ratio is smaller than 0.7, the overall weight increases, and if it is larger than 0.99, the strength of the cladding joint surface decreases, which is not preferred in practice. Thereafter, each of the eyeglass frame members is brazed to assemble the eyeglass frame. In this brazing work, Ni or
Since the sheath material 2 made of Ni-based alloy becomes the joint,
Can be easily brazed. Next, the eyeglass frame is subjected to a plating process. This plating treatment is a treatment after brazing, and since it is a treatment applied to the outer surface of the sheath material 2 made of Ni or Ni-based alloy, it is easy to obtain a plated surface with good plating and a good finish. Next, we will actually make the glasses frame and calculate its weight.
The results of experiments conducted regarding brazing strength, bending strength, and corrosion resistance will be explained. First, it is made of pure Ti, with a diameter of 50 mm and a length of 1000 mm.
Ni-based alloy (components shown in the table below) is used as the core material.
A composite material is formed by covering it with a sheath material with an outer diameter of 50.5 mm, an inner diameter of 50 mm, and a length of 1000 mm.
Extrusion molding was performed using a hot isostatic extruder at 700°C to produce an extruded wire rod with a diameter of 10 mm. Next, the extruded wire rod was annealed at about 600 to 700° C. to soften it, and then cold drawn to obtain a wire rod with a diameter of 5 mm. This wire rod was then annealed at 600 to 700°C and subjected to cold drawing to produce a wire rod for eyeglass frames with a diameter of 2.6 mm. Regarding the weight, brazing strength, bending strength, and corrosion resistance of the eyeglass frame manufactured based on the above-mentioned wire rod for eyeglass frames, using the core material and sheath material having the composition shown in the table below, the same procedure as the above-mentioned procedure was performed. Experiments were conducted on the weight, brazing strength, bending strength, and corrosion resistance of eyeglass frames manufactured using the . The results are shown in the table on the next page.

[Table] The composition of the artificial sweat used in the experiment is as shown below, and a corrosion resistance experiment was conducted by immersing it in this artificial sweat for 5 days. Sodium chloride 9.8g/Urea 1.7g/Glucose 0.2g/Lactic acid 0.8cc Sodium sulfide 0.8g/Aqueous ammonia 0.02g/Water balance This is a value obtained by manufacturing each eyeglass frame using the material and measuring the breaking strength when peeling off the bridge part and rim part. In addition, bending strength was determined by fixing one end of the temple part of a 0.9 mm thick and 3.5 mm wide eyeglass frame, setting the span to 45 mm, and applying a load to the other end using a cantilever type, resulting in a permanent strain with a displacement of 1 mm. This is the value obtained by measuring the load at the time. As is clear from the experimental results shown in Table 1 above, the eyeglass frames manufactured according to the above-mentioned procedure were:
It is lightweight, has high brazing strength, and has excellent corrosion resistance against artificial sweat. In terms of bending strength, a Ti-only structure is too low and insufficient for use in eyeglass frames, but the present invention improves the bending strength to a moderate value. It has become clear that it can be used almost as well as Ni-based alloys and Ni-based alloys. "Effects of the Invention" As explained above, the present invention provides Ti or Ti
A core material made of a base alloy is covered with a sheath material made of Ni or a Ni-based alloy, subjected to extrusion processing, and further subjected to wire drawing processing to form an eyeglass frame member.Then, the eyeglass frame member is brazed, and then This is a plating process, and in order to perform brazing using a sheath material with good brazing properties provided on the outside of the core material, the brazed part is stronger than that of a single titanium eyeglass frame. This has the effect that it is possible to easily manufacture eyeglass frames having the above. In addition, in order to manufacture eyeglass frames by performing plating treatment after brazing and using a sheath material made of Ni or Ni-based alloy as a base, we provide a well-finished plating surface that is free of scratches and stains. This has the effect of making it possible to manufacture eyeglass frames having the following properties. Furthermore, since the final step is plating after assembling the eyeglass frame by brazing the eyeglass frame components such as the rim, temple, and bridge parts, there will be no damage to the finished eyeglass frame. You can get eyeglass frames with beautiful surfaces. That is, as explained above, according to the present invention,
It is lightweight, has high strength, and has good brazing properties.
This has the effect of being able to provide an eyeglass frame that has a beautiful plating surface without scratches in the final product state.
