Description

本発明は、軸線回りに回転するダイの外周面に形成された刃型とアンビルロールとの間にシート状の被加工物を挟み込んで被加工物を加工するロータリーダイに関する。   The present invention relates to a rotary die for processing a workpiece by sandwiching a sheet-like workpiece between an edge mold formed on an outer peripheral surface of a die rotating around an axis and an anvil roll.

従来、シート状の被加工物を所定の形状で裁断する裁断加工や、積層した複数の被加工物を押圧して被加工物同士を圧着する圧着加工や、被加工物に凹凸のエンボスを形成するエンボス加工には、ロータリーダイが用いられている。この種のロータリーダイは、例えば図３及び図４に示すように、略円柱状に形成されたダイ１とアンビルロール２とを備え、このダイ１とアンビルロール２とが互いに軸線Ｏ１、Ｏ２を平行させつつそれぞれ軸線回りに回転可能に設けられている。そして、ダイ１の外周面１ａに形成された刃型１ｂとアンビルロール２との間にシート状の被加工物Ｓを送り込むことにより被加工物Ｓを加工することが可能とされている。   Conventionally, cutting processing to cut a sheet-like workpiece into a predetermined shape, press-bonding processing that presses a plurality of stacked workpieces and crimping them together, and forming uneven embossing on the workpieces A rotary die is used for embossing. For example, as shown in FIGS. 3 and 4, this type of rotary die includes a die 1 and an anvil roll 2 formed in a substantially cylindrical shape, and the die 1 and the anvil roll 2 have axes O 1 and O 2. Each is provided so as to be rotatable around an axis while being parallel. Then, the workpiece S can be processed by feeding the sheet-like workpiece S between the blade mold 1 b formed on the outer peripheral surface 1 a of the die 1 and the anvil roll 2.

図３から図５に示した被加工物Ｓの裁断加工に用いられるロータリーダイにおいて、ダイ１の外周面１ａに形成される刃型１ｂは、軸線Ｏ１に対する径方向外側に突出しつつ被加工物Ｓの加工形状（図では、被加工物Ｓの上面側からの対向視に略矩形形状）に合うように外周面１ａに沿って延設されている。そして、先端の鋭利な刃先１ｃを回転する硬質のアンビルロール２の外周面２ａに押圧させて、ダイ１とアンビルロール２の回転とともにこの間に送り込まれた被加工物Ｓを順次切断してゆくものとされている。   In the rotary die used for the cutting of the workpiece S shown in FIGS. 3 to 5, the blade die 1b formed on the outer peripheral surface 1a of the die 1 projects outward in the radial direction with respect to the axis O1. Is extended along the outer peripheral surface 1a so as to match the processed shape (in the figure, a substantially rectangular shape when viewed from the upper surface side of the workpiece S). Then, the cutting edge 1c having a sharp tip is pressed against the outer peripheral surface 2a of the rotating hard anvil roll 2, and the workpiece S fed in the meantime is sequentially cut along with the rotation of the die 1 and the anvil roll 2. It is said that.

このような刃型１ｂの先端側の刃先１ｃは、先端に径方向に直交する平面状に形成された先端平滑面１ｄと、この先端平滑面１ｄの幅方向の両側端側から下方に向かうに従い漸次幅方向外側に傾斜する研削傾斜面１ｅと、研削傾斜面１ｅの下端側から下方に向かうに従い漸次外側に傾斜する焼結生地面１ｆとを備え、径方向先端側に凸となるように形成されている。また、研削傾斜面１ｅには、先端平滑面１ｄとの交差稜線と平行する図示せぬ複数の研削筋（ノッチ）が形成されている。   The cutting edge 1c on the tip side of such a blade mold 1b has a tip smooth surface 1d formed in a flat shape perpendicular to the tip in the radial direction, and downward from both side ends in the width direction of the tip smooth surface 1d. Grinding inclined surface 1e that is gradually inclined outward in the width direction, and a sintered material surface 1f that is gradually inclined outward from the lower end side of the inclined inclined surface 1e, and formed so as to be convex toward the distal end side in the radial direction. Has been. In addition, a plurality of grinding streaks (notches) (not shown) parallel to the intersecting ridge line with the tip smooth surface 1d are formed on the inclined grinding surface 1e.

一方、上記の刃先１ｃにおいては、アンビルロール２に押圧される運転初期に、研削傾斜面１ｅに前記交差稜線に平行して形成された研削筋が、刃先１ｃにチッピングを誘発してしまい、ダイ１の寿命を短かくするという問題が生じていた。また、ダイ１の外周面１ａから***して突設された刃型１ｂで被加工物Ｓの裁断を行う際には、ダイ１の軸線Ｏ１方向に延設された刃先１ｃに比べて、ダイ１の周方向に延設された刃先１ｃの接触面圧が大きくなり、延設方向により刃先１ｃの摩耗の程度が異なって切断性能を維持することができなくなるという問題が生じていた。   On the other hand, in the above cutting edge 1c, at the initial stage of operation when pressed by the anvil roll 2, the grinding lines formed in parallel to the intersecting ridge line on the grinding inclined surface 1e induce chipping on the cutting edge 1c, The problem of shortening the lifetime of 1 occurred. Further, when cutting the workpiece S with the blade mold 1b protruding from the outer peripheral surface 1a of the die 1, the die 1 is compared with the blade edge 1c extending in the direction of the axis O1 of the die 1. The contact surface pressure of the cutting edge 1c extending in the circumferential direction of 1 increases, and the degree of wear of the cutting edge 1c differs depending on the extending direction, which makes it impossible to maintain cutting performance.

これに対して、特許文献１に開示されたロータリーダイ（ダイカットロール）は、刃先の先端平滑面と研削傾斜面との間に、先端平滑面の幅方向の両側端側から研削傾斜面に向かうに従い漸次幅方向外側に傾斜する仕上げ傾斜面が加えられて形成されている。また、この仕上げ傾斜面には、先端平滑面との交差稜線に対して５０〜９０°の角度で交差する研削筋が形成されるとともに、その表面粗度（Ｒａ）を０．１μｍとすることによって、研削筋の形成によるチッピングの誘発をなくし、刃先にチッピングが生じることを抑制することが可能とされている。また、軸線方向の刃先の幅ｄａと頂角θａ、及び周方向の刃先の幅ｄｃと頂角θｃを、それぞれ、５≦ｄａ≦１０μｍ、６０≦θａ≦１２０°、１０≦ｄｃ≦３０μｍ、８０≦θｃ≦１４０°、θａ≦θｃとすることによって、軸線方向の刃先と周方向の刃先の接触面圧差を解消して切断性能を維持することが可能とされている。
特開平１１−１８８６９８号公報 On the other hand, the rotary die (die-cut roll) disclosed in Patent Document 1 is directed to the grinding inclined surface from the both sides in the width direction of the tip smooth surface between the tip smooth surface and the grinding inclined surface of the cutting edge. Accordingly, a finish inclined surface that is gradually inclined outward in the width direction is added. In addition, grinding streaks that intersect at an angle of 50 to 90 ° with respect to the intersecting ridge line with the tip smooth surface are formed on the finished inclined surface, and the surface roughness (Ra) is 0.1 μm. By this, it is possible to eliminate the induction of chipping due to the formation of grinding lines and to suppress the occurrence of chipping at the blade edge. Further, the width da and apex angle θa of the cutting edge in the axial direction, and the width dc and apex angle θc of the cutting edge in the circumferential direction are respectively 5 ≦ da ≦ 10 μm, 60 ≦ θa ≦ 120 °, 10 ≦ dc ≦ 30 μm, 80 By satisfying ≦ θc ≦ 140 ° and θa ≦ θc, it is possible to eliminate the contact surface pressure difference between the cutting edge in the axial direction and the cutting edge in the circumferential direction and maintain the cutting performance.
JP-A-11-188698

しかしながら、上記の特許文献１に開示されたロータリーダイにおいては、先端平滑面と仕上げ傾斜面、研削傾斜面、焼結生地面がそれぞれ平面とされているため、各面が連接する部分には、交差稜線が画成されてエッジが形成されることになる。このように、平面同士の交差稜線に画成されたエッジを有する刃先においては、被加工物の裁断時に生じる接触圧がエッジ部分に集中して大きく作用することになり、このエッジ部分にチッピングが生じやすくなってしまうという問題があった。   However, in the rotary die disclosed in the above-mentioned Patent Document 1, since the tip smooth surface, the finish inclined surface, the grinding inclined surface, and the sintered dough surface are each flat, in the part where each surface is connected, An intersecting ridge line is defined to form an edge. As described above, in a cutting edge having an edge defined by intersecting ridge lines between planes, the contact pressure generated at the time of cutting the workpiece is concentrated and acts on the edge portion, and chipping is applied to the edge portion. There was a problem that it was likely to occur.

また、上記の特許文献１に開示されるようなロータリーダイにおいては、該特許文献１にも記載されているように、マシニングセンタによって一旦仕上げられた極小の刃先の先端平滑面と研削傾斜面との間に、さらに仕上げ傾斜面を研削加工によって形成し、かつ交差稜線に対する交差角度を規定した研削筋をも形成することになるため、その精度を機械加工で確保することが困難で、例えば顕微鏡を用いた手作業による形成が必要とされる。このような場合には、刃型の製作労力の増大、ひいては製造コストの増大を招くという問題があった。   Further, in the rotary die as disclosed in the above-mentioned Patent Document 1, as described in the Patent Document 1, the tip smooth surface and the grinding inclined surface of the extremely small cutting edge once finished by the machining center are used. In the meantime, since the finished inclined surface is further formed by grinding and a grinding line defining the crossing angle with respect to the crossing ridgeline is also formed, it is difficult to ensure the accuracy by machining, for example, a microscope The manual formation used is required. In such a case, there has been a problem that the manufacturing effort of the blade mold is increased, and consequently the manufacturing cost is increased.

本発明は、上記事情を鑑み、チッピングが発生しにくく耐久性に優れ、機械加工によっても形成可能な刃型を備えたロータリーダイを提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a rotary die provided with a blade die that is less likely to cause chipping and has excellent durability and can be formed by machining.

上記の目的を達するために、この発明は以下の手段を提供している。   In order to achieve the above object, the present invention provides the following means.

本発明のロータリーダイは、軸線回りに回転される円柱状のダイの外周面に、この外周面から***するように形成された刃型が延設され、該刃型と前記ダイの外周面に対向して設けられるアンビルロールとの間で被加工物を挟み込んで前記被加工物を加工するロータリーダイにおいて、前記刃型の先端側が刃先とされ、該刃先には、その先端に先端平滑面が設けられており、該先端平滑面と前記刃型の側面が、前記刃型の延設方向に垂直な断面において外側に凸の曲面を介して連接されていることを特徴とする。   In the rotary die of the present invention, a blade die formed so as to protrude from the outer peripheral surface is extended on the outer peripheral surface of a cylindrical die rotated around an axis, and the blade die and the outer peripheral surface of the die are extended. In a rotary die for processing a workpiece by sandwiching the workpiece with an anvil roll provided oppositely, the tip side of the blade mold is a blade tip, and the tip of the blade has a smooth tip surface at the tip. The tip smooth surface and the side surface of the blade mold are connected to each other through a curved surface protruding outward in a cross section perpendicular to the extending direction of the blade mold.

本発明のロータリーダイによれば、先端平滑面と刃型の側面とが刃型の外側に凸の曲面を介して連接されていることにより、従来のロータリーダイと比較して、被加工物の裁断時に接触圧をこの曲面で分散させて受けることができるため、エッジ部分に接触圧が集中的に大きく作用して刃先にチッピングが生じることを防止でき、刃型の耐久性を向上させることができる。   According to the rotary die of the present invention, the tip smooth surface and the side surface of the blade die are connected to the outside of the blade die via a convex curved surface, so that the workpiece can be compared with a conventional rotary die. Since the contact pressure can be distributed and received at this curved surface during cutting, it can prevent the contact pressure from intensively acting on the edge part and cause chipping at the blade edge, and improve the durability of the blade mold. it can.

また、刃型の先端平滑面と側面とを曲面を介して連接させる場合には、例えば機械加工で刃先を形成することも可能になり、刃型の製作労力を軽減し、ひいては製造コストの削減を図ることが可能になる。   In addition, when connecting the tip smooth surface and side surface of the blade mold via a curved surface, it is possible to form the blade tip by, for example, machining, which reduces the manufacturing effort of the blade mold and thus reduces the manufacturing cost. Can be achieved.

以下、図１から図４を参照し、本発明の一実施形態について説明する。本実施形態は、シート状の被加工物を所定の形状で裁断する裁断加工に用いられるロータリーダイに関するものである。なお、本実施形態のロータリーダイは、前述の図３及び図４に示したロータリーダイに対して刃先の形状を変えたものである。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The present embodiment relates to a rotary die used for a cutting process for cutting a sheet-like workpiece into a predetermined shape. In addition, the rotary die of this embodiment changes the shape of a blade edge with respect to the rotary die shown in above-mentioned FIG.3 and FIG.4.

本実施形態のロータリーダイは、前述と同様、図３及び図４に示すように、略円柱状に形成されたダイ１とアンビルロール２とが主な構成要素とされ、このダイ１とアンビルロール２は、それぞれの軸部１ｇ、２ｂが図示せぬベアリングボックスに支持され、かつ図示せぬ駆動装置に少なくとも一方の軸部１ｇ（２ｂ）が連結されて矢印Ｒ１、Ｒ２方向にそれぞれ回転可能に設けられている。   As shown in FIGS. 3 and 4, the rotary die of the present embodiment includes a die 1 and an anvil roll 2 formed in a substantially columnar shape as main components, as shown in FIGS. 3 and 4. 2, each shaft portion 1g, 2b is supported by a bearing box (not shown), and at least one shaft portion 1g (2b) is connected to a drive device (not shown) so as to be rotatable in the directions of arrows R1, R2. Is provided.

また、ダイ１には、その外周面１ａに、外周面１ａから軸線Ｏ１に対する径方向外側に突出するように***した刃型１ｂが裁断される被加工物の形状に合わせて延設され、この刃型１ｂの径方向外側の先端部分が刃先１ｃとされている。   Further, the die 1 is extended on the outer peripheral surface 1a in accordance with the shape of the workpiece to be cut, the blade mold 1b protruding so as to protrude radially outward from the outer peripheral surface 1a with respect to the axis O1. A tip portion on the radially outer side of the blade mold 1b is a blade tip 1c.

ここで、本実施形態の刃型１ｂの刃先１ｃには、図１及び図２に示すように、該刃型１ｂの延設方向に垂直な断面において、先端に平面状に形成された先端平滑面１ｄが設けられている。また、刃型１ｂの側面１ｈは、刃型１ｂの突出方向先端側から後端に向かうに従い漸次幅方向外側に傾斜する傾斜面とされている。   Here, as shown in FIGS. 1 and 2, the cutting edge 1c of the blade mold 1b of the present embodiment has a smooth tip formed in a flat shape at the tip in a cross section perpendicular to the extending direction of the blade mold 1b. A surface 1d is provided. Further, the side surface 1h of the blade mold 1b is an inclined surface that gradually inclines outward in the width direction from the front end side in the protruding direction of the blade mold 1b toward the rear end.

そして、先端平滑面１ｄと側面１ｈは、前記断面において刃型１ｂの外側に向けて凸の曲面１ｉを介して連接され、この曲面１ｉは、先端平滑面１ｄ及び側面１ｈの少なくとも一方と接することなく交差稜線を画成するように設けられている。また、この曲面１ｉは、前記断面において、例えば半径５〜５０μｍの円弧状とされる。   The smooth end surface 1d and the side surface 1h are connected to each other via a curved surface 1i that protrudes outward from the blade mold 1b in the cross section, and the curved surface 1i is in contact with at least one of the smooth end surface 1d and the side surface 1h. It is provided to define the intersection ridgeline. In addition, the curved surface 1i has, for example, an arc shape with a radius of 5 to 50 μm in the cross section.

ついで、上記の構成からなるロータリーダイの作用及び効果について説明する。   Next, the operation and effect of the rotary die having the above configuration will be described.

ダイ１とアンビルロール２を、少なくとも一方の軸部１ｇ（２ｂ）が駆動部に接続された図示せぬ駆動装置の駆動によって、それぞれ軸線Ｏ１、Ｏ２回りに矢印Ｒ１、Ｒ２方向に回転させる。そして、回転するダイ１とアンビルロール２の間に、シート状の被加工物Ｓを送り込むことによって、ダイ１とアンビルロール２の回転とともにこの間を被加工物Ｓが走行することとなり、この間、刃型１ｂの刃先１ｃとアンビルロール２の外周面２ａとで被加工物Ｓが押圧されつつ挟み込まれて刃型１ｂで所定の形状をなす裁断が行われる。   The die 1 and the anvil roll 2 are rotated in the directions of arrows R1 and R2 around the axes O1 and O2, respectively, by driving of a driving device (not shown) in which at least one shaft 1g (2b) is connected to the driving unit. Then, by feeding the sheet-like workpiece S between the rotating die 1 and the anvil roll 2, the workpiece S travels along with the rotation of the die 1 and the anvil roll 2. The workpiece S is sandwiched while being pressed between the cutting edge 1c of the mold 1b and the outer peripheral surface 2a of the anvil roll 2, and cutting is performed in a predetermined shape with the blade mold 1b.

ここで、本実施形態のロータリーダイにおいては、刃型１ｂの刃先１ｃの先端平滑面１ｄと刃型１ｂの側面１ｈとが、刃型１ｂの外側に向けて凸の曲面１ｉを介して連接されているため、曲面１ｉと、先端平滑面１ｄ及び側面１ｈとの連接部分に交差稜線が画成されてエッジが形成されている場合においても、従来のロータリーダイの刃先１ｃよりもエッジが鈍角とされ、被加工物Ｓに切り込まれる刃先１ｃに作用する接触圧がエッジ部分に集中して作用することがなく、刃先１ｃの曲面１ｉ全体で接触圧を受け止め、これを分散させることが可能とされる。このため、本実施形態のロータリーダイにおいては、従来の刃型のようにエッジ部分に応力集中が生じることによって刃先１ｃにチッピングが発生することを防止できる。   Here, in the rotary die of the present embodiment, the tip smooth surface 1d of the blade tip 1c of the blade mold 1b and the side surface 1h of the blade mold 1b are connected via a curved surface 1i that protrudes outward from the blade mold 1b. Therefore, even in the case where an edge is formed by defining an intersecting ridge line at the connecting portion between the curved surface 1i, the tip smooth surface 1d, and the side surface 1h, the edge is more obtuse than the cutting edge 1c of the conventional rotary die. The contact pressure acting on the cutting edge 1c cut into the workpiece S does not concentrate on the edge portion, and the contact pressure can be received and dispersed by the entire curved surface 1i of the cutting edge 1c. Is done. For this reason, in the rotary die of this embodiment, it is possible to prevent chipping from occurring at the cutting edge 1c due to stress concentration at the edge portion as in the conventional blade type.

したがって、上記のロータリーダイによれば、先端平滑面１ｄと刃型１ｂの側面１ｈとが曲面１ｉを介して連接されていることにより、刃型１ｂの耐久性を高めることができる。よって、ロータリーダイの耐久性の向上を図ることが可能になる。   Therefore, according to the above rotary die, the end smooth surface 1d and the side surface 1h of the blade mold 1b are connected via the curved surface 1i, whereby the durability of the blade mold 1b can be enhanced. Therefore, it is possible to improve the durability of the rotary die.

また、先端平滑面１ｄと刃型１ｂの側面１ｈとを連接させる刃型１ｂの外側に凸の曲面１ｉは、例えば機械加工で容易に形成することが可能であり、刃型１ｂの製作労力の軽減、ひいては製造コストの削減を図ることが可能になる。   Further, the curved surface 1i that protrudes outward from the blade mold 1b that connects the tip smooth surface 1d and the side surface 1h of the blade mold 1b can be easily formed by, for example, machining, and the manufacturing effort of the blade mold 1b is reduced. It becomes possible to reduce the manufacturing cost.

以上、本発明に係るロータリーダイの一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。例えば、本実施形態では、刃型１ｂの先端平滑面１ｄと側面１ｈの間に曲面１ｉが設けられ、これらの連設部分に交差稜線が画成されてエッジが形成されているものとしたが、この曲面１ｉと、先端平滑面１ｄ及び側面１ｈとが滑らかに連接されてエッジが形成されていなくてもよく、この場合には、さらに接触圧を分散させることが可能とされ、刃先１ｃにチッピングが発生することをより確実に防止することが可能とされる。   As mentioned above, although one Embodiment of the rotary die concerning this invention was described, this invention is not limited to said one Embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, in the present embodiment, the curved surface 1i is provided between the tip smooth surface 1d and the side surface 1h of the blade mold 1b, and an edge is formed by defining an intersecting ridge line at these connecting portions. The curved surface 1i, the tip smooth surface 1d, and the side surface 1h need not be smoothly connected to form an edge. In this case, the contact pressure can be further dispersed, and the cutting edge 1c can be dispersed. It is possible to more reliably prevent occurrence of chipping.
