この実施例におけるローレット加工装置は、締付け工具の把持部など円柱状の被加工物１の外周面にローレット模様を形成するもので、外周面に多条溝状のローレット目Ａが周設された一対の丸形ダイス２，３と、この両丸形ダイス２，３間に配設された被加工物１の支持台４とで概略構成されており、前記一対の丸形ダイス２，３は、互いの回転軸心２ａ，３ａを同一線上に配置させた態様で平行に配設され、支持台４上に載置した被加工物１の中心を両丸形ダイス２，３の軸心２ａ，３ａと同一線上に配列させた状態で、この丸形ダイス２，３を回転動すると共に、被加工物１方向に押圧動することにより、互いの周面が接触しながら回転動する過程において被加工物１の外周面にローレット加工するもので、ここでは、各丸形ダイス２，３の外周面に多数の斜目条溝によるローレット目Ａが周設されており、これにより被加工物１の外周面１ａには、網目（あや目とも称される）ローレット模様Ｂが形成される（図１、図２）。   The knurl processing apparatus in this embodiment forms a knurl pattern on the outer peripheral surface of a cylindrical workpiece 1 such as a gripping part of a tightening tool, and multi-groove knurls A are provided around the outer peripheral surface. The pair of round dies 2 and 3 and a support base 4 of the workpiece 1 disposed between the round dies 2 and 3 are schematically configured. The rotational axes 2a and 3a are arranged in parallel in a manner in which the rotational axes 2a and 3a are arranged on the same line, and the center of the workpiece 1 placed on the support 4 is centered on the axes 2a of the double dies 2 and 3 , 3a in a state where they are arranged on the same line as the circular dies 2, 3 while rotating and pressing in the direction of the workpiece 1, the peripheral surfaces of the circular dies rotate in contact with each other. The outer peripheral surface of the workpiece 1 is knurled. Here, each round die 2 A knurl A having a large number of oblique grooves is provided around the outer peripheral surface of the work piece 3. As a result, a mesh (also referred to as a “ya”) knurled pattern B is formed on the outer peripheral surface 1a of the workpiece 1. (FIGS. 1 and 2).

そしてこのローレット加工装置にあっては、被加工物１の外周面１ａに、前記のごとくローレット模様Ｂを形成すると同時に、このローレット模様Ｂ域内の所定の個所に、ローレット模様Ｂがない無模様部１ｂを設けると共に、この無模様部１ｂに商標、品番や図柄などＣを刻印加工するもので、この実施例では、被加工物１の外周面１ａにおける円周上等位置となる２個所に前記刻印加工をするものである。   In the knurling apparatus, the knurled pattern B is formed on the outer peripheral surface 1a of the workpiece 1 as described above, and at the same time, the non-patterned portion having no knurled pattern B at a predetermined portion in the knurled pattern B area. 1b is provided, and the non-patterned portion 1b is engraved with a trademark, a product number, a pattern, and the like C. In this embodiment, the above-described two positions on the circumference of the outer peripheral surface 1a of the workpiece 1 are equal to each other. Engraving is performed.

しかして、各丸形ダイス２，３には、被加工物１の円周寸法の２分の１の寸法Ｄをもって各丸形ダイス２，３の円周を等分割した外周面上の各部位、換言すれば、この丸形ダイス２，３の回転軸心２ａ，３ａを中心として等円弧角度となる外周面上の各部位に、方形の穴５が凹設されており、これにより各丸形ダイス２，３は、ローレット目Ａの周設域内に、このローレット目Ａが省略された省略部２ｂ，３ｂが形成される。   Thus, each of the round dies 2 and 3 has each part on the outer peripheral surface obtained by equally dividing the circumference of each of the round dies 2 and 3 with a dimension D that is a half of the circumference of the workpiece 1. In other words, a square hole 5 is recessed in each part on the outer peripheral surface having an equal arc angle around the rotation axes 2a, 3a of the round dies 2, 3 so that each round In the dies 2 and 3, omitted portions 2 b and 3 b in which the knurled eye A is omitted are formed in the peripheral area of the knurled eye A.

更にこの丸形ダイス２，３の一方端面には、各穴５方向に有底の挿入孔２ｃ，３ｃが穿設され、挿入孔２ｃ，３ｃと各穴５との間にネジ孔２ｄ，３ｄが設けられており、一方の丸形ダイス２の各穴５には、商標や品番、図柄などの刻印版６が、印面をローレット目Ａ面と同面とした状態で嵌め込まれ、挿入孔２ｃ，３ｃから挿入した止めネジ７によりネジ孔２ｄ，３ｄを介して固定されてなるもので（図３、４）、この両丸形ダイス２、３は、加工時にあって各丸形ダイス２，３に凹設された互いの穴５が同回転角度を維持しつつ回転動するように同期回転制御される。   Further, one end face of each of the round dies 2 and 3 is provided with bottomed insertion holes 2c and 3c in the direction of each hole 5, and screw holes 2d and 3d between the insertion holes 2c and 3c and each hole 5. A marking plate 6 such as a trademark, product number, or design is fitted in each hole 5 of one of the round dies 2 in a state where the marking surface is the same surface as the knurled eye A surface, and the insertion hole 2c , 3c are fixed through screw holes 2d, 3d by set screws 7 (FIGS. 3 and 4). These round dies 2 and 3 are formed at the time of processing. Synchronous rotation control is performed such that the holes 5 recessed in 3 rotate while maintaining the same rotation angle.

そして、支持台４に被加工物１を載置して両丸形ダイス２，３を同期回転動すると共に、被加工物１方向に押圧動することにより、各丸形ダイス２，３に周設されたローレット目Ａにより被加工物１の外周面１ａにローレット模様Ｂ（この例では網目）が形成されると共に、一方の丸形ダイス２の穴５に嵌合固定された刻印版６により、ローレット模様Ｂ域内の円周上の２個所に商標、品番や図柄などが刻印されるもので（図５）、この際両丸形ダイス２，３は同期回転されているので、刻印個所は他方の丸形ダイス３の穴５に合致して潰されることなく刻設される。   Then, the work piece 1 is placed on the support base 4 and both the round dies 2 and 3 are synchronously rotated and pressed in the direction of the work piece 1 so that the round dies 2 and 3 are moved around. A knurled pattern B (mesh in this example) is formed on the outer peripheral surface 1a of the workpiece 1 by the knurled stitch A provided, and the stamped plate 6 is fitted and fixed in the hole 5 of one round die 2. The trademark, product number, and design are engraved at two locations on the circumference of the knurled pattern B area (Fig. 5). At this time, since the double round dies 2 and 3 are rotated synchronously, the engraving location is The other round die 3 is engraved without being crushed to match the hole 5.

すなわち、直径３０ｍｍの被加工物１の外周面１ａにおける円周上の等位置となる２個所に、直径１２０ｍｍの丸形ダイス２，３で刻印加工をする例にあっては、丸形ダイス２，３の回転軸心２ａ，３ａを中心として等円弧角４５°となる外周面上の各部位（円弧寸法４７．１ｍｍ）８個所に方形の穴５を設けることとなる（図１、２）。   That is, in an example in which two round dies 2 and 3 having a diameter of 120 mm are engraved at two positions on the outer circumferential surface 1a of the workpiece 1 having a diameter of 30 mm, the circular dies 2 , 3 square shafts 5 are provided at eight positions (circular dimensions 47.1 mm) on the outer peripheral surface having an equal arc angle of 45 ° with the rotation axis 2a, 3a as the center (FIGS. 1 and 2). .

勿論刻印個所数や位置及び刻印形状すなわち丸形ダイス２，３に凹設された穴５の個数、位置、形状は任意であり、また刻印を要しない場合は、各穴５に嵌合固定された刻印版６を取り外すことにより、ローレット目Ａが省略された穴５部分（省略部２ｂ，３ｂ）がローレット模様Ｂ域内において無模様部１ｂとして表出され、この穴５（省略部２ｂ，３ｂ）の形状、大きさや配置を考慮することにより、これがローレット模様Ｂ域における柄ともなるもので（図７）、これは、穴５を凹設することなく、丸形ダイス２，３に周設されたローレット目Ａの所望個所を所望形状に省略（削除）することによっても可能である。   Of course, the number and position of the stamped parts and the stamped shape, that is, the number, position and shape of the holes 5 recessed in the round dies 2 and 3 are arbitrary, and when not stamped, they are fitted and fixed in the holes 5. By removing the engraving plate 6, the hole 5 portion (omitted portions 2b, 3b) from which the knurled eye A is omitted is exposed as the non-patterned portion 1b in the knurled pattern B area, and the holes 5 (omitted portions 2b, 3b) are exposed. ) In consideration of the shape, size, and arrangement of (), this also becomes a pattern in the knurled pattern B area (FIG. 7), which is provided around the circular dies 2 and 3 without the hole 5 being recessed. It is also possible to omit (delete) a desired portion of the knurled eye A in a desired shape.

前記のごとくこの実施例のローレット加工装置によれば、ローレット加工時における両丸形ダイス２，３と被加工面１の周面接触回転動にあって、両丸形ダイス２，３の同期回転に伴ない、被加工物１の外周面１ａ上の所定個所と合致する各丸形ダイス２，３の外周面上の部位に、前記所定個所をローレット模様がない無模様部１ｂにすることとなると共に、ローレット目を省略（削除）した省略部２ａ，３ａとなる穴５が凹設されており、そしてこの省略部２ａ，３ａである穴５は、商標、商品番号や図柄などの刻印版６が配設可能に構成され、一方の丸形ダイス２の穴５に刻印版６を配設固定して被加工物１を加工するものであるから、被加工物の外周面にローレット模様を形成すると共に、このローレット模様域内に商標などを刻印表示することができるのみか、図柄表示も可能であり、更に刻印版を取外した状態で加工することにより、ローレット模様域内に無模様個所が表出され、これが柄ともなるものであり、しかも所望の形状、大きさ、配置の刻印表示や無模様の形成も可能となるものである。   As described above, according to the knurl processing apparatus of this embodiment, both the round dies 2 and 3 and the work surface 1 are in contact with each other at the time of knurl processing. Accordingly, a predetermined portion on the outer peripheral surface of each of the round dies 2 and 3 that coincides with a predetermined portion on the outer peripheral surface 1a of the workpiece 1 is formed as a non-patterned portion 1b having no knurled pattern.
