Composite material in which a base metal or base metal alloy core material such as Cu alloy, Ni-Cr-Cu-Mn alloy, stainless steel alloy, nickel silver, or Monel is coated with Au-based alloy or Pt-based alloy such as 12K, 14K, or 18K. etc. were used. To manufacture a deformed rim wire for eyeglasses from a composite wire made of a base metal or a base metal alloy coated with a noble metal or noble metal alloy layer among these materials, first, the composite round wire 1 shown in Fig. 1 is processed by die drawing. As shown in FIG. 2, the irregular rim wire 2 is formed into an inverted trapezoidal cross section with no dents, and then the upper center of the irregular rim wire 2 is gradually passed through the irregular die 11 times and the irregular roll 9 times or more. As shown in FIG. 3, a U-shaped irregular rim wire 4 was manufactured by forming a recess 3.

としての商品価値が著しく低下するという欠点が
あつた。 However, in such a conventional method for manufacturing irregularly shaped rim wires, when the depth of the recess 3 becomes deeper than the width of the recess 3, the flow of the material deteriorates, and the heights of the right shoulder 3' and the left shoulder 3'' decrease. When the eyeglass rim line and the lens are not aligned horizontally, there may be a problem that the lens cannot be aligned perpendicularly to the eyeglass rim line, and the hardness of the bottom of the recess 3 will increase, causing the precious metal or precious metal alloy layer to It has the disadvantage that it becomes extremely thin or, in severe cases, breaks, exposing the base metal or base metal alloy inside, which corrodes during use, and its commercial value as an eyeglass rim wire is significantly reduced.
本発明はかかる問題点を解決すべくなされたも

法を提供せんとするものである。 The present invention has been made to solve these problems, and it is possible to easily produce a modified rim wire for eyeglasses having a desired cross-sectional shape with uniform hardness and a uniform thickness of the precious metal or precious metal alloy layer. The purpose is to provide a manufacturing method.

る。 The method for manufacturing a modified rim wire for eyeglasses according to the present invention includes:
A composite wire made of a base metal or a base metal alloy coated with a noble metal or noble metal alloy layer is formed into a tape with a predetermined flat approximately trapezoidal cross section using a modified roll or a modified die, and then this flat tape with approximately trapezoidal cross section is The central part is gradually and evenly bent using a modified roll or a modified die, so that the top side of the tape with a substantially trapezoidal cross section has the concave shape of a modified rim wire, and the bottom and both oblique sides have the outer circumferential shape of a modified rim wire. It is something.

を特徴とするものである。 In other words, the method for manufacturing a modified rim wire for eyeglasses of the present invention, when manufacturing a modified rim wire with a U-shaped or V-shaped cross-section, involves forming a round wire into a flat tape with a substantially trapezoidal cross-section; This tape is characterized by gradually bending the central portion of the tape to create an irregular rim line in which the oblique side of a substantially trapezoid having a desired indentation on the inside is horizontal.

等しくなるように成形することをいう。 Hereinafter, a specific example will be explained with reference to the drawings.First, a composite round wire 1, which is a round wire made of a base metal or a base metal alloy and coated with a layer of a noble metal or a noble metal alloy on the outer periphery, is formed using a deformed roll or a deformed die. Fourth
As shown in the figure, it is formed into a tape 5 having a predetermined flat, substantially trapezoidal cross section. Here, the predetermined flat approximately trapezoidal cross section is formed so that the area of the approximately trapezoidal cross section is equal to the area of the cross section of the final molded U-shaped irregular rim line in FIG. The dimension of the upper side 5a of the cross section is equal to the inner surface dimension of the recess of the U-shaped irregular rim line of the final molding, and the dimension of the oblique sides 5b on both sides is equal to the upper side of the U-shaped irregular rim line of the final molding. This means that the dimension of the bottom side 5c is the same as the dimension of the outer periphery of the final U-shaped irregular rim line.
このように所定の扁平な略台形状断面になした

み６を有する異型リム線７を作る。 The tape 5 thus formed into a predetermined flat, substantially trapezoidal cross-section is then gradually and evenly bent at the center using a modified roll or a modified die, as shown in FIG. 6. A deformed rim line 7 having a desired recess 6 inside is made.
ここでテープ５を徐々に折曲げ加工する理由に
ついて述べれば、Ni−Cr系合金等の眼鏡用異型
リム線の材料は塑性変形しがたく、逆に貴金属又
は貴金属合金被覆層は塑性変形しやすい為、一気
に折曲げ加工することが困難であり、外周の貴金
属又は貴金属合金層に局所的な伸びと縮みが発生
して破断してしまうからである。 Here, the reason for gradually bending the tape 5 is that the material of the irregular rim wire for eyeglasses, such as Ni-Cr alloy, is difficult to deform plastically, whereas the noble metal or precious metal alloy coating layer is easily deformed plastically. Therefore, it is difficult to bend the material all at once, and local elongation and shrinkage occur in the outer circumferential noble metal or noble metal alloy layer, resulting in breakage.
前記テープ５を徐々に折曲げ加工するというこ
とは、通常異型ダイスで３回から10回、異型ロー
ルで３回から８回通すことを意味する。３回はい
ずれも眼鏡用異型リム線７の被覆層が均一に加工
される為の最低回数である。 Gradual bending of the tape 5 usually means passing it through a profile die 3 to 10 times and a profile roll 3 to 8 times. Three times is the minimum number of times in order to uniformly process the coating layer of the irregularly shaped rim wire 7 for eyeglasses.
かように折曲げ加工された内側に凹み６を有す
る異型リム線７は、被覆層が均一な厚さで加工さ
れ、しかも異形リム線７の左右の肩部が水平で表
面に全く傷が付かず、材料硬化も起こらず、満足

用いた異型ダイスや異型ロールは焼き付くことが
なかつた。従つて、従来のように貴金属又は貴金
属合金層の破断による内部の腐蝕等を防止するこ
とができる。 The irregularly shaped rim wire 7 having the recess 6 on the inside that has been bent in this way has a coating layer of a uniform thickness, and the left and right shoulders of the irregularly shaped rim wire 7 are horizontal and there is no scratch on the surface. There was no hardening of the material, resulting in a satisfactory shaped rim wire 7 for eyeglasses, and the shaped dies and shaped rolls used for molding the wire did not seize. Therefore, it is possible to prevent internal corrosion caused by breakage of the noble metal or noble metal alloy layer as in the conventional case.
以上詳記した通り、本発明の製造方法により複
合丸線から異型リム線を作つた場合外周の貴金属
又は貴金属合金層を破断することなく均一な厚さ
にできるので、腐蝕等の発生がない等の優れた効
果がある。 As detailed above, when a deformed rim wire is made from a composite round wire using the manufacturing method of the present invention, it can be made to have a uniform thickness without breaking the noble metal or precious metal alloy layer on the outer periphery, so there is no occurrence of corrosion etc. It has excellent effects.
