Description
本発明は、研磨シートに関するものである。 The present invention relates to a polishing sheet.
従来、材料を寸法に合うように削ったり、形状を整えたり、細かい部分の錆を落としたりする手動工具として、金属やすりが用いられている。一般的な金属やすりは、棒状の金属体の表面に目を形成したものであり、目が形成された表面を材料に押し当てながら研削するようになっている。金属やすりの目は、一つ一つ鏨（たがね）を打ち込んで形成される（目立て）。また、金属やすりの目には、単目、複目、シャリ目、波目等がある。 Conventionally, a metal file has been used as a manual tool for scraping a material to fit its dimensions, adjusting its shape, and removing rust in small parts. A general metal file has eyes formed on the surface of a rod-shaped metal body, and the surface on which the eyes are formed is pressed against a material for grinding. The metal file is formed by driving chisel one by one (sharpening). In addition, the eyes of the metal file include single eyes, double eyes, sushi rice, and wavy eyes.
また、紙状のシートに研磨材を塗布した紙やすり（サンドペーパー）も用いられている。紙やすりは、厚紙や油紙等の紙の表面に研磨材を接着したものであり、研磨材が接着された表面を材料に押し付けてこすりながら研磨するようになっている。 In addition, sandpaper, which is a paper-like sheet coated with an abrasive, is also used. Sandpaper is made by adhering an abrasive to the surface of paper such as thick paper or oil paper, and the surface to which the abrasive is adhered is pressed against the material and rubbed while polishing.
また、特許文献１には、研磨材が被覆された薄いプレートをハンドル部に磁力で保持するようにして、研磨部を容易に付け替えたり、裏返して使用できるようにした手動研ぎ具に関する発明が記載されている。 Further, Patent Document 1 describes an invention relating to a manual sharpener in which a thin plate coated with an abrasive is magnetically held by a handle portion so that the polished portion can be easily replaced or turned inside out. Has been done.
しかしながら、従来の金属やすりの目は、目立て打ち込み方向（鏨の進入方向）が、棒状の金属体の長手方向に沿った一方向であるため、押す方向でのみ使用し、引く方向で使用することはできない。そのため、紙やすりのように、材料をこすりながら（押し引きしながら）研磨する用途には適していない。これは、単目に限らず、複目、シャリ目、波目等においても同様である。 However, since the conventional metal file has a sharpening driving direction (the direction in which the chisel enters) is one direction along the longitudinal direction of the rod-shaped metal body, it should be used only in the pushing direction and in the pulling direction. Can't. Therefore, it is not suitable for sanding while rubbing (pushing and pulling) the material, such as sandpaper. This is the same not only for the single eye, but also for the compound eye, the rice grain, the wave, and the like.
一方、紙やすりは、厚紙や油紙等の紙の表面に研磨材を接着したものであるため、目の方向性はなく、あらゆる方向にこすりながら研磨することができる。しかしながら、金属やすりに比べると切削能力が低く、また耐久性が低いため、切削能力の低下、目詰まり、破れが頻繁に発生するという問題がある。 On the other hand, since sandpaper is made by adhering an abrasive to the surface of paper such as cardboard or oil paper, it has no directionality of the eyes and can be polished while rubbing in all directions. However, since the cutting ability is lower and the durability is lower than that of a metal file, there is a problem that the cutting ability is lowered, clogging, and tearing frequently occur.
本発明は、上記従来の課題を解決するものであり、あらゆる方向に使用可能で切削能力が高く、耐久性に優れた研磨シートを提供するものである。 The present invention solves the above-mentioned conventional problems, and provides a polishing sheet that can be used in all directions, has high cutting ability, and has excellent durability.
上記課題を解決するため、本発明の研磨シートは、板状の金属部材からなる本体部と、前記本体部に形成された３つの異なる方向の目とを有し、前記３つの異なる方向の目の目立て打ち込み方向が３方向から向き合っていることを特徴とする。 In order to solve the above problems, the polishing sheet of the present invention has a main body portion made of a plate-shaped metal member and three eyes in different directions formed on the main body portion, and the eyes in the three different directions. It is characterized in that the sharpening driving directions of the above are facing from three directions.
また好ましくは、前記３つの異なる方向の目の交点が不規則に配置されていることを特徴とする。 It is also preferable that the intersections of the three eyes in different directions are irregularly arranged.
本発明の研磨シートは、板状の金属部材からなる本体部と、本体部に形成された３つの異なる方向の目とを有し、３つの異なる方向の目の目立て打ち込み方向が３方向から向き合っており、目立て打ち込み方向が一方向に偏っていない。従って、一方向にのみ切削するのではなく、あらゆる方向に使用可能であり、材料をこすりながら研磨することができる。また、金属部材であるので、切削能力が高く耐久性に優れている。 The polishing sheet of the present invention has a main body portion made of a plate-shaped metal member and three different directions of eyes formed on the main body portion, and the sharpening driving directions of the three different directions face each other from the three directions. The sharpening driving direction is not biased in one direction. Therefore, it can be used in all directions instead of cutting in only one direction, and the material can be polished while rubbing. Moreover, since it is a metal member, it has high cutting ability and excellent durability.
また、３つの異なる方向の目の交点が不規則に配置されている場合には、研磨方向による切削能力の偏りがより少なくなる。 Further, when the intersections of the eyes in the three different directions are irregularly arranged, the deviation of the cutting ability depending on the polishing direction becomes smaller.
以上、本発明によれば、あらゆる方向に使用可能で切削能力が高く、耐久性の高い研磨シートを提供することができる。 As described above, according to the present invention, it is possible to provide a polishing sheet that can be used in all directions, has a high cutting ability, and has high durability.
次に、図１乃至図８を参照して、本発明の実施形態に係る研磨シートについて説明する。図１に示すように、本実施形態に係る研磨シート１００は、板状の金属部材からなる本体部１から構成されている。本体部１の金属部材は特に限定されないが、例えばステンレス板を用いることができる。 Next, the polishing sheet according to the embodiment of the present invention will be described with reference to FIGS. 1 to 8. As shown in FIG. 1, the polishing sheet 100 according to the present embodiment is composed of a main body 1 made of a plate-shaped metal member. The metal member of the main body 1 is not particularly limited, but a stainless steel plate can be used, for example.
本体部１の表面には、３つの異なる方向の目１０，２０，３０が形成されている。これらは、本体部１の表面に鏨を打ち込んで目立てすることにより、目１０→目２０→目３０の順に形成される。以降、目１０を「下目１」、目２０を「下目２」、目３０を「上目」と適宜称する。次に、３つの目１０，２０，３０における、各々の目立てについて説明する。 On the surface of the main body 1, three eyes 10, 20, and 30 in different directions are formed. These are formed in the order of eyes 10 → eyes 20 → eyes 30 by driving a chisel into the surface of the main body 1 to sharpen it. Hereinafter, the eyes 10 will be referred to as "lower eyes 1", the eyes 20 will be referred to as "lower eyes 2", and the eyes 30 will be referred to as "upper eyes" as appropriate. Next, each of the three stitches 10, 20, and 30 will be described.
図２は、目１０（下目１）の説明図である。本体部１の表面には、等間隔で平行に形成された複数本の目１０が形成されている。図２における本体部１の右辺を基準線１２とすると、目１０と基準線１２とのなす角度はθ１である。また、矢印１１は、目１０の形成時の目立て打ち込み方向（鏨の進入方向）を示しており、図２における左上から右下に向かって打ち込みが行われる。 FIG. 2 is an explanatory view of the eye 10 (lower eye 1). On the surface of the main body 1, a plurality of eyes 10 formed in parallel at equal intervals are formed. Assuming that the right side of the main body 1 in FIG. 2 is the reference line 12, the angle formed by the eye 10 and the reference line 12 is θ1. Further, the arrow 11 indicates the sharpening driving direction (the approaching direction of the chisel) at the time of forming the mesh 10, and the driving is performed from the upper left to the lower right in FIG.
図３は、目２０（下目２）の説明図である。本体部１の表面には、等間隔で平行に形成された複数本の目２０が形成されている。図３における本体部１の左辺を基準線２２とすると、目２０と基準線２２とのなす角度はθ２である。また、矢印２１は、目２０の形成時の目立て打ち込み方向（鏨の進入方向）を示しており、図３における右上から左下に向かって打ち込みが行われる。 FIG. 3 is an explanatory view of eyes 20 (lower eyes 2). A plurality of eyes 20 formed in parallel at equal intervals are formed on the surface of the main body 1. Assuming that the left side of the main body 1 in FIG. 3 is the reference line 22, the angle formed by the eye 20 and the reference line 22 is θ2. Further, the arrow 21 indicates the sharpening driving direction (the approaching direction of the chisel) at the time of forming the eye 20, and the driving is performed from the upper right to the lower left in FIG.
図４は、目３０（上目）の説明図である。本体部１の表面には、等間隔で平行に形成された複数本の目３０が形成されている。図４における本体部１の右辺を基準線３２とすると、目３０と基準線３２とのなす角度はθ３である。また、矢印３１は、目３０の形成時の目立て打ち込み方向（鏨の進入方向）を示しており、図４における下から上に向かって打ち込みが行われる。 FIG. 4 is an explanatory view of eyes 30 (upper eyes). On the surface of the main body 1, a plurality of eyes 30 formed in parallel at equal intervals are formed. Assuming that the right side of the main body 1 in FIG. 4 is the reference line 32, the angle formed by the eye 30 and the reference line 32 is θ3. Further, the arrow 31 indicates the sharpening driving direction (the approaching direction of the chisel) at the time of forming the stitch 30, and the driving is performed from the bottom to the top in FIG.
図５は、目立て打ち込み角度を示す図である。矢印１１，２１，３１は、それぞれ目１０，２０，３０の形成時の目立て打ち込み方向（鏨の進入方向）を示しており、本体部１の表面と矢印１１，２１，３１とのなす角度はθ４である。 FIG. 5 is a diagram showing a sharpening driving angle. Arrows 11 and 21,31 indicate the sharpening driving direction (the direction in which the chisel enters) when the eyes 10, 20, and 30, respectively, and the angle formed by the surface of the main body 1 and the arrows 11, 21, and 31 is It is θ4.
図６は、図１のａ部拡大図である。図６に示すように、３つの異なる方向の目１０，２０，３０の目立て打ち込み方向１１，２１，３１が３方向から向き合っている。すなわち、３つの目立て打ち込み方向である矢印１１，２１，３２が向き合うことにより、目１０，２０、３０の打ち込み方向が一方向に偏らないようになっている。本実施形態では、矢印１１及び矢印２１が図６における上から下に向いているのに対して、矢印３１は下から上に向いている。従って、図６の上下方向において、目１０及び目２０に対して目３０が逆目になっている。これにより、使用時の方向が限定されないようになっている。 FIG. 6 is an enlarged view of part a in FIG. As shown in FIG. 6, the sharpening driving directions 11, 21, and 31 of the eyes 10, 20, and 30 in three different directions face each other from the three directions. That is, by facing the arrows 11, 21, 32, which are the three sharpening driving directions, the driving directions of the eyes 10, 20, and 30 are not biased in one direction. In this embodiment, the arrows 11 and 21 point from top to bottom in FIG. 6, while the arrow 31 points from bottom to top. Therefore, in the vertical direction of FIG. 6, the eyes 30 are reversed with respect to the eyes 10 and 20. As a result, the direction of use is not limited.
さらに、３つの異なる方向の目１０，２０，３０の交点が不規則に配置されている。すなわち、ある部分では目１０と目２０との交点上を目３０が通り、他の部分では目１０と目２０との交点以外の部分を目３０が通っている。これにより、目１０，２０，３０の規則性を低下させて、研磨方向による切削能力の偏りを少なくしている。 Furthermore, the intersections of the eyes 10, 20, and 30 in three different directions are irregularly arranged. That is, in one part, the eye 30 passes over the intersection of the eyes 10 and the eye 20, and in the other part, the eye 30 passes through a part other than the intersection of the eyes 10 and the eyes 20. As a result, the regularity of the eyes 10, 20, and 30 is reduced, and the bias of the cutting ability depending on the polishing direction is reduced.
