Abstract

A blade for cutting a thin body, capable of smoothly punching the thin body and allowing a punched-out product (such as precision optical film) punched out of the thin body to be smoothly removed from the punch edge. A blade for cutting a thin body, formed by cutting a metallic block or a metallic plate as the raw material and provided with a punch edge.  Cut streaks formed on either one and/or the other of the side surfaces of the punch edge are formed in such a manner that the cut streaks are perpendicular to the tip line of the punch edge or that the angle of the cut streaks relative to the tip line is not less than 45 degrees but less than 90 degrees.  Also, the blade can have punch edges formed in steps.  In this case, the blade is configured in such a manner that the cut streaks formed on either one and/or the other of the side surfaces of each of all the steps or any of the steps are arranged so as to be perpendicular to the tip line of the punch edge or to be tilted relative to the tip line at an angle not less than 45 degrees but less than 90 degrees.

Description

薄状体用切断刃Cutting blade for thin body
　本発明は、切削形成された打ち抜き刃を備えた薄状体用切断刃に関し、特に液晶フィルム，粘着層を有するフィルム，ハードコート層を有する有機ＥＬフィルム，太陽光発電パネルのカバーフィルム等の機能性フィルム（打ち抜き対象物）の打ち抜きに際して、切断部がきれいな（高品質の打ち抜き製品が生成できる）薄状体用切断刃に関する。 TECHNICAL FIELD The present invention relates to a cutting blade for a thin body provided with a punched cutting blade, and in particular, functions such as a liquid crystal film, a film having an adhesive layer, an organic EL film having a hard coat layer, a cover film for a photovoltaic power generation panel, and the like. The present invention relates to a cutting blade for a thin body having a clean cutting part (a high-quality punched product can be generated) when punching a conductive film (punching object).
　近年、光学用等の合成樹脂フィルムやシート等の薄状体を高い品質で（高精度で）打ち抜く技術が要求されるようになっている。この要求に応えるために金属ブロックを削り出して、打ち抜き刃を回転切削刃（エンドミル等）により切削形成してなる薄状体用切断刃が知られている。
　図１３（Ａ）に打ち抜き刃形成前の抜き型９０を示す。この抜き型９０は、基台９１上に打ち抜き刃の輪郭部分９２だけを残して掘削加工されている。 In recent years, a technique for punching thin bodies such as optical synthetic resin films and sheets with high quality (with high accuracy) has been required. In order to meet this requirement, a thin-body cutting blade is known in which a metal block is cut out and a punching blade is formed by cutting with a rotary cutting blade (end mill or the like).
FIG. 13A shows a punching die 90 before forming the punching blade. This punching die 90 is excavated on the base 91 while leaving only the outline 92 of the punching blade.
　打ち抜き刃は、次のように輪郭部分９２を切削することで形成される。すなわち、図１３（Ｂ）の側面図（断面図）および図１３（Ｃ）の正面図に示すように、エンドミル９４の中心軸を打ち抜き刃の刃先ライン９３に垂直に配置し、エンドミル９４と抜き型９０とを、刃先ライン９３に平行に相対移動させてエンドミル９４の側部により打ち抜き刃の側面の切削を行っている。なお、図１３（Ｂ），（Ｃ）では、エンドミル９４を固定して、抜き型９０をｘ方向に移動させて切削する様子を示してある。 The punching blade is formed by cutting the contour portion 92 as follows. That is, as shown in the side view (sectional view) in FIG. 13B and the front view in FIG. 13C, the center axis of the end mill 94 is arranged perpendicular to the cutting edge line 93 of the punching blade, The die 90 is moved relative to the cutting edge line 93 in parallel, and the side of the punching blade is cut by the side of the end mill 94. FIGS. 13B and 13C show a state where the end mill 94 is fixed and the die 90 is moved in the x direction for cutting.
　しかし、上記のようにして作製された従来の抜き型では図１３（Ｃ）に示すように、切削条痕Ｓが打ち抜き刃９の刃先ライン９３に平行に形成される。このため、図１４に示すように、作製された打ち抜き刃９では、薄状体Ｆの打ち抜きがスムーズに行われず、高品質の製品ができにくいという問題がある。図１４では、二段刃（一段目を符号９２１で、二段目を符号９２２で示してある）に構成した場合において、薄状体Ｆ（製品フィルム）が切削条痕Ｓの突起部分に引っかかる様子を示してある（符号ｇ１，ｇ２参照）。 However, in the conventional punch produced as described above, the cutting streak S is formed in parallel to the cutting edge line 93 of the punching blade 9 as shown in FIG. For this reason, as shown in FIG. 14, the manufactured punching blade 9 has a problem that the thin body F is not smoothly punched, and it is difficult to produce a high-quality product. In FIG. 14, in the case of a two-stage blade (the first stage is indicated by reference numeral 921 and the second stage is indicated by reference numeral 922), the thin body F (product film) is caught by the protruding portion of the cutting streak S. The situation is shown (see symbols g1 and g2).
　なお、図１５（Ａ）に示すような帯状刃（トムソン刃）９６の作製に際しては、帯状刃９６を移動させつつグラインダー９９により刃先を切削するので、切削条痕Ｓは図１５（Ｂ）に示すようにトムソン刃の刃先ライン９７に垂直に形成される。しかし、トムソン刃９６は、曲げ加工して形作られるために打ち抜き精度が悪い。このため、高精度が要求される打ち抜き加工には使用されない。 Note that when the band-shaped blade (Thomson blade) 96 as shown in FIG. 15A is manufactured, the cutting edge S is cut as shown in FIG. As shown, it is formed perpendicular to the cutting edge line 97 of the Thomson blade. However, since the Thomson blade 96 is formed by bending, the punching accuracy is poor. For this reason, it is not used for the punching which requires high accuracy.

　以下、 金属板材を原材として本発明の薄状体用切断刃をＮＣ加工機を用いて作製する実施形態を説明する。
　図１（Ｂ），（Ｃ）に打ち抜き刃形成前の抜き型（単に「抜き型」と言う）２０を示す。図１（Ｂ）の抜き型２０は、図１（Ａ）の金属プレート１を、エンドミルまたは他の掘削装置を用いて切削（掘削）加工したもので、基台２１上に打ち抜き刃の輪郭部分（突出部）２２が残されて形成されている。図１（Ｃ）の抜き型２０は、図１（Ａ）の金属プレート１を、ワイヤーカッタを用いてくり抜いたもので、図１（Ｂ）の抜き型２０と同様、基台２１上に打ち抜き刃の輪郭部分（突出部）２２が残されて形成されている。 Hereinafter, an embodiment in which the cutting blade for a thin body of the present invention is produced using an NC processing machine using a metal plate material as a raw material will be described.
FIGS. 1B and 1C show a punching die 20 (hereinafter simply referred to as “punching die”) 20 before the punching blade is formed. A punching die 20 in FIG. 1B is obtained by cutting (excavating) the metal plate 1 in FIG. 1A using an end mill or another excavating device. The (projection) 22 is left and formed. The punching die 20 in FIG. 1 (C) is obtained by punching the metal plate 1 in FIG. 1 (A) using a wire cutter and punching it on the base 21 like the punching die 20 in FIG. 1 (B). The contour portion (projecting portion) 22 of the blade is left and formed.
　最初の実施形態では、打ち抜き刃は、次のように形成される。すなわち、図２（Ａ）の側面図（断面図）および図２（Ｂ）の正面図に示すように、先端に半球切削刃を持つエンドミル３を、中心軸Ｌが突出部２２の側面に平行（金属プレート１の表面に垂直）となるように配置する。図２（Ａ），（Ｂ）では、打ち抜き刃の側面の傾斜（援鉛直上方に対して面がなす角度）をθで示す。たとえば、θは５・から６０・（好ましくは、１５・から２０・）の範囲から適宜選択できる。 In the first embodiment, the punching blade is formed as follows. That is, as shown in the side view (sectional view) of FIG. 2A and the front view of FIG. 2B, the end mill 3 having a hemispherical cutting blade at the tip is provided, and the central axis L is parallel to the side surface of the protrusion 22. It arrange | positions so that it may become (perpendicular to the surface of the metal plate 1). In FIGS. 2A and 2B, the inclination of the side surface of the punching blade (the angle formed by the surface with respect to the top of the assist vertical) is represented by θ. For example, θ can be appropriately selected from the range of 5 · 60 · (preferably 15 · 20 ·).
　そして、エンドミル３を、打ち抜き刃の側面に沿って上下に往復移動（図面上では＋γ／－γ方向に往復移動）させつつ、打ち抜き刃の想定される刃先ライン２３に平行に（図２（Ｂ）では－α方向）移動させる。これにより、エンドミル３の先端側部により、打ち抜き刃の側面の切削が行われる。 Then, the end mill 3 is reciprocated up and down along the side surface of the punching blade (reciprocating in the + γ / −γ direction in the drawing) and parallel to the assumed cutting edge line 23 of the punching blade (FIG. 2 (B ) To move in the -α direction. Thereby, the side of the punching blade is cut by the tip side portion of the end mill 3.
　本実施形態では、エンドミル３が上下に１往復する間に、抜き型２０とエンドミル３とを－α方向に微小距離（たとえば、１μｍから５０μｍ、好ましくは５μｍから３０μｍ）移動させている。これにより、打ち抜き刃の側面には、図２（Ｂ）に示したよう、想定される刃先ライン２３に垂直にまたは当該想定刃先ラインに対する角度が９０・未満４５・以上の範囲となるように切削条痕Ｔが形成され、フィルム等の打ち抜きに際して品質の高い（切断面がきれいな）製品を製造できる。 In this embodiment, while the end mill 3 reciprocates up and down once, the die 20 and the end mill 3 are moved by a minute distance (for example, 1 μm to 50 μm, preferably 5 μm to 30 μm) in the −α direction. As a result, as shown in FIG. 2B, the side surface of the punching blade is cut so as to be perpendicular to the assumed cutting edge line 23 or at an angle with respect to the assumed cutting edge line of 90 · less than 45 ·. A streak T is formed, and a high quality product (having a clean cut surface) can be manufactured when a film or the like is punched.
　図３（Ａ）から（Ｆ）は、半球切削形状を持つエンドミル３を打ち抜き刃の側面に沿って往復移動させて切削を行う他の実施形態を示している。すなわち、図３（Ａ）から（Ｄ）に示すように、まず、エンドミル３を下降、上昇（すなわち、－γ，＋γ方向に移動）させることにより抜き型２０の側面を切削する。 3 (A) to 3 (F) show another embodiment in which cutting is performed by reciprocating the end mill 3 having a hemispherical cutting shape along the side surface of the punching blade. That is, as shown in FIGS. 3A to 3D, first, the side face of the die 20 is cut by lowering and raising the end mill 3 (that is, moving in the −γ and + γ directions).
　この後、図３（Ｅ）に示すように、エンドミル３を抜き型２０から離し、想定された刃先ライン２３に平行に（すなわち、－α方向に）、微小距離（たとえば、２μｍから１００μｍ）だけ移動させ、図３（Ａ）の状態に戻す（図３（Ｆ）は図３（Ａ）と同じである）。
　図３（Ａ）から（Ｆ）の実施形態においても、切削条痕が、打ち抜き刃の刃先ライン２３に垂直に形成されるので、フィルム等の打ち抜きに際して品質の高い（切断面がきれいな）製品を製造できる。 Thereafter, as shown in FIG. 3 (E), the end mill 3 is separated from the punching die 20, and is parallel to the assumed cutting edge line 23 (that is, in the -α direction) by a minute distance (for example, 2 μm to 100 μm). Move to return to the state of FIG. 3A (FIG. 3F is the same as FIG. 3A).
In the embodiment of FIGS. 3 (A) to 3 (F), since the cutting streak is formed perpendicular to the cutting edge line 23 of the punching blade, a product with high quality (a clean cut surface) can be obtained when punching a film or the like. Can be manufactured.
　図４（Ａ）から（Ｉ）は、エンドミル３を打ち抜き刃の側面に沿って往復移動させて切削を行うさらに他の実施形態を示している。この実施形態では、抜き型２０とエンドミル３との刃先ライン２３に平行な相対移動（横移動）を、エンドミル３の最上位置と最下位置との間で行っている。 4A to 4I show still another embodiment in which cutting is performed by reciprocating the end mill 3 along the side surface of the punching blade. In this embodiment, relative movement (lateral movement) parallel to the cutting edge line 23 between the punching die 20 and the end mill 3 is performed between the uppermost position and the lowermost position of the end mill 3.
