本発明は、眼鏡用つまりレンズを保持する為の
リム線の製造方法に係り、特に断面Ｕ字形或いは
Ｖ字形の複合材から成るリム線の製造方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a rim wire for eyeglasses, that is, for holding lenses, and more particularly to a method for manufacturing a rim wire made of a composite material and having a U-shaped or V-shaped cross section.
従来、この種のリム線の材料としては、Ni−

凹み３を形成してＵ字型リム線４を製造してい
た。 Conventionally, the material for this type of rim wire was Ni-
Cr-based alloys, Ni-Cr-Mn-based alloys, Ni-Cr-Cu-based alloys, Ni-Cr-Cu-Mn-based alloys, stainless steel alloys, nickel silver, Monel, Au-based alloys such as 12K, 14K, 18K, etc. Composite solid wires made of Pt-based alloys and the like are used, and in order to manufacture eyeglass rim wires from these materials, first coat the round wire 1a shown in Fig. 1 with a covering material 1b.
The composite round wire 1 coated with is formed into a rim wire 2 with a cross-sectional shape without a concave shape as shown in FIG. As shown in FIG. 3, a U-shaped rim wire 4 was manufactured by forming a recess 3.
然し乍ら、かかる従来のリム線の製造方法では
第２図の如き凹みのない断面形状のリム線２にな
した後、その上面中央部に第３図の如く凹み３を
形成すると、その凹みの底部の被覆材１ｂが極端
に薄くなつたり、ひどい時には破断して内部の材
料が露出し、これが使用時に腐蝕するので、眼鏡
リム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 rim wire manufacturing method, after forming the rim wire 2 with a cross-sectional shape without a recess as shown in FIG. 2, if a recess 3 is formed in the center of the upper surface as shown in FIG. The covering material 1b becomes extremely thin or, in severe cases, breaks, exposing the internal material, which corrodes during use, resulting in a significant reduction in the commercial value of the eyeglass rim.
本発明はかかる問題点の解決すべくなされたも
のであり、所要の断面形状の眼鏡用リム線を極め
て簡単に作ることのできる製造方法を提供せんと
するものである。 The present invention has been made to solve these problems, and it is an object of the present invention to provide a manufacturing method that can extremely easily produce a rim wire for eyeglasses having a desired cross-sectional shape.
本発明による眼鏡用リム線の製造方法は、複合
中空丸線を異形ロール又は異形ダイスにより塑性
加工して、内側に所望の凹を有するリム線に仕上
げることを特徴とするものである。 The method for producing a rim wire for eyeglasses according to the present invention is characterized in that a composite hollow round wire is plastically worked using a modified roll or a modified die to form a rim wire having a desired concavity on the inside.
換言すれば、本発明の眼鏡用リム線の製造方法
は、Ｕ字形又はＶ字形の断面形状のリム線を製造
するに当り複合中空丸線の一部を窪ませるかある
いは、複合中空丸線を扁平な断面のテープに成形
し、このテープの左右両側端部を徐々に折曲げ加
工して内側に所望の凹みを有するリム線を作るこ
とを特徴とするものである。 In other words, the method for manufacturing a rim wire for eyeglasses of the present invention involves recessing a portion of the composite hollow round wire or recessing a portion of the composite hollow round wire when manufacturing the rim wire having a U-shaped or V-shaped cross section. It is characterized in that it is formed into a tape with a flat cross section, and the left and right end portions of this tape are gradually bent to form a rim line having a desired indentation on the inside.
本発明に於いて、複合丸線を中空にしている理
由は、リム線の塑性加工時の変形抵抗を軽減して
被覆材のみが伸びて極端に薄くなつたり、破断た
りするのを防止するためである。 In the present invention, the reason why the composite round wire is made hollow is to reduce the deformation resistance during plastic processing of the rim wire and prevent the covering material from stretching and becoming extremely thin or breaking. It is.
尚、複合中空丸線の肉厚は、外径の10％未満で
は機械的強さが十分でなく25％を超えると厚すぎ
てリム線への塑性加工が難しいので、外径の10〜
25％が好ましい。 Note that if the wall thickness of the composite hollow round wire is less than 10% of the outer diameter, the mechanical strength will not be sufficient, and if it exceeds 25%, it will be too thick and difficult to plastically process into a rim wire.
25% is preferred.
以下その具体的な実施例を図によつて説明する
と、先ず第４図に示す洋白の中空丸線５ａに12金
５ｂを被覆した複合中空丸線（外径2.5mm、内径
1.65mm）５を異形ロール又は異形ダイスにより第
５図に示す如く断面ハート型複合中空線のに成形
する。 Below, a specific example will be explained with reference to the drawings. First, as shown in Fig. 4, a composite hollow round wire (outer diameter 2.5 mm, inner diameter
1.65 mm) 5 was formed into a heart-shaped composite hollow wire in cross section as shown in FIG. 5 using a modified roll or a modified die.
このように断面ハート型になした複合中空線６
は、その後徐々に異形ロール又は異形ダイスによ
り塑性加工して、第６図に示す如く内側に所望の
凹み７を有するリム線８を作る。 Composite hollow wire 6 with a heart-shaped cross section like this
Thereafter, the rim wire 8 is gradually plastically worked using a modified roll or a modified die to form a rim line 8 having a desired recess 7 on the inside as shown in FIG.
かように塑性加工された内側に凹み７を有する
リム線８は、外周の12金が破断することなくその
厚さも均一であつた。 In the rim wire 8 having the recess 7 on the inside that was plastically worked in this way, the 12-karat gold on the outer periphery did not break and its thickness was uniform.
以上詳記した通り、本発明による眼鏡用リム線
の製造方法によれば、凹みを形成するときの変形
抵抗が小さく中空丸線と被覆材が同じように変形
し、被覆材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優れた効果がある。 As described in detail above, according to the method of manufacturing a rim wire for eyeglasses according to the present invention, the deformation resistance when forming a recess is small, and the hollow round wire and the covering material deform in the same way, without breaking the covering material. Since it can be made to have a uniform thickness, it has an excellent effect of preventing corrosion and the like.
