Description

本発明は、打ち抜き加工装置に関する。   The present invention relates to a punching apparatus.

従来の打ち抜き加工装置では、打ち抜き刃を有する第１ローラと打ち抜き穴を有する第２ローラとを互いに逆方向に同一周速度で回転させ、両ローラ間に金属箔等のワークを通過させることでワークに打ち抜き加工を行っている。   In a conventional punching device, a first roller having a punching blade and a second roller having a punching hole are rotated in opposite directions at the same peripheral speed, and a workpiece such as a metal foil is passed between both rollers. Is punched.

特開２０１０−５５５号公報JP 2010-555 A

しかしながら、上記従来技術にあっては、第１ローラ外周面に形成した雌ねじ部に打ち抜き刃に形成した雄ねじ部をねじ込むことで打ち抜き刃を第１ローラに取り付けているため、打ち抜き刃毎に突出量を計測しながら、ねじ込み量を調整する必要があり、組み付けに手間が掛かるという問題があった。
本発明の目的は、打ち抜き刃の組み付け性を向上させた打ち抜き加工装置を提供することにある。 However, in the above prior art, since the punching blade is attached to the first roller by screwing the male screw portion formed on the punching blade into the female screw portion formed on the outer peripheral surface of the first roller, the protruding amount for each punching blade. There is a problem that it is necessary to adjust the screwing amount while measuring, and it takes time to assemble.
An object of the present invention is to provide a punching apparatus that improves the assembling property of a punching blade.

上述の課題を解決するために、本発明では、第１ローラを円筒状として貫通穴を形成し、貫通穴の内側から頭部が第１ローラの内周面と接触した状態まで挿通したボルト型部材の胴部先端に打ち抜き刃を形成し、軸方向移動規制部材によりボルト型部材の軸方向移動を規制した。さらに、頭部に平面部を形成して回転規制部材の側面を当接させてボルト型部材の回転を規制した。

In order to solve the above-described problems, in the present invention, a bolt type in which a first roller is formed in a cylindrical shape and a through hole is formed, and the head is inserted from the inside of the through hole to a state in contact with the inner peripheral surface of the first roller. A punching blade was formed at the front end of the body portion of the member, and the axial movement of the bolt-type member was regulated by the axial movement regulating member. Further, a flat portion was formed on the head, and the side surface of the rotation restricting member was brought into contact with the head to restrict the rotation of the bolt type member.

本発明において、打ち抜き刃の突出量は第１ローラの肉厚（第１ローラの外周面と内周面との間の距離）とボルト型部材の胴部の長さとで決まる。ここで、両者の寸法はあらかじめ精度良く加工することが可能であるから、本発明の打ち抜き加工装置によれば、各ボルト型部材を第１ローラに取り付ける際の突出量の調整を省略できる。この結果、打ち抜き刃の組み付け性の向上を図ることができる。また、回転規制部材でボルト型部材の回転を規制するようにしたので、ボルト型部材の組み付け時に、これらの方向誤差があっても自動的に適正な方向に修正できる。

In the present invention, the protruding amount of the punching blade is determined by the thickness of the first roller (the distance between the outer peripheral surface and the inner peripheral surface of the first roller) and the length of the body of the bolt-type member. Here, since both dimensions can be processed with high accuracy in advance, according to the punching apparatus of the present invention, it is possible to omit adjustment of the protrusion amount when each bolt type member is attached to the first roller. As a result, the assembling property of the punching blade can be improved. In addition, since the rotation of the bolt-type member is restricted by the rotation restricting member, even when there is such a direction error when the bolt-type member is assembled, it can be automatically corrected to an appropriate direction.

以下、本発明の打ち抜き加工装置を実施するための形態を、図面に示す実施例に基づいて説明する。   EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the punching apparatus of this invention is demonstrated based on the Example shown on drawing.

〔実施例１〕
[全体構造]
図１は実施例１の打ち抜き加工装置の側面図、図２は実施例１の打ち抜き加工装置の断面図である。
実施例１の打ち抜き加工装置は、平板状のワークAを挟んで上下に配置された第１ローラ1と第２ローラ2を備える。実施例１では、ワークAとして、排気ガス浄化用のメタル触媒担体の金属箔、例えば、厚さが20〜30μmのステンレスを用いている。 [Example 1]
[Overall structure]
FIG. 1 is a side view of the punching apparatus according to the first embodiment, and FIG. 2 is a cross-sectional view of the punching apparatus according to the first embodiment.
The punching apparatus according to the first embodiment includes a first roller 1 and a second roller 2 that are disposed above and below a flat workpiece A. In Example 1, as the work A, a metal foil of a metal catalyst carrier for purifying exhaust gas, for example, stainless steel having a thickness of 20 to 30 μm is used.

第１ローラ1は、円筒状に形成され、回転軸O1により回動可能に支持されている。第１ローラ1の一端には、第１ギア1aが連結されている。このギア1aは図外の電動モータのモータ出力軸と連結されている。
第１ローラ1の外周面1bには、ワークAの打ち抜き用の雄型となる複数の打ち抜き刃3が放射状に突出している。打ち抜き刃3は、周方向に22.5°ピッチで16個並んだものが第１ローラ1の軸方向に5列配置されている。１つの列の打ち抜き刃3は、隣接する列の打ち抜き刃3に対し、周方向位置が11.25°ずれている。 The first roller 1 is formed in a cylindrical shape and is rotatably supported by a rotation shaft O1. A first gear 1 a is connected to one end of the first roller 1. The gear 1a is connected to a motor output shaft of an electric motor (not shown).
On the outer peripheral surface 1b of the first roller 1, a plurality of punching blades 3 serving as male dies for punching the workpiece A project radially. Sixteen punching blades 3 arranged at a pitch of 22.5 ° in the circumferential direction are arranged in five rows in the axial direction of the first roller 1. The circumferential positions of the punching blades 3 in one row are shifted from the punching blades 3 in the adjacent row by 11.25 °.

図３に打ち抜き刃3の形状を示す。
打ち抜き刃3には、打ち抜き刃3の軸方向において最も長い（以下、軸方向長さを高さという。）頂部21aを挟んで第１ローラ回転方向側に前方傾斜面22が設けられ、第１ローラ回転方向と反対側に後方傾斜面23が設けられている。前方傾斜面22および後方傾斜面23は、いずれも直線で形成された平面である。
頂部21aは、打ち抜き刃3の周方向中心位置よりも第１ローラ回転方向前方に配置され、第１ローラ周方向と直交する方向に延在している。前方傾斜面22は、頂部21aから第１ローラ回転方向に進むに従って低くなる（第１ローラ1の外周面1aとの距離が近くなる）。後方傾斜面23は、頂部21aから第１ローラ回転方向と反対方向に進むに従って低くなる。 FIG. 3 shows the shape of the punching blade 3.
The punching blade 3 is provided with a front inclined surface 22 on the first roller rotation direction side with a top 21a sandwiched between the longest in the axial direction of the punching blade 3 (hereinafter, the axial length is referred to as height). A rear inclined surface 23 is provided on the side opposite to the roller rotation direction. Both the front inclined surface 22 and the rear inclined surface 23 are flat surfaces formed by straight lines.
The top portion 21a is disposed in front of the circumferential direction center position of the punching blade 3 in the first roller rotation direction, and extends in a direction orthogonal to the first roller circumferential direction. The forward inclined surface 22 becomes lower as it advances from the top portion 21a in the first roller rotation direction (the distance from the outer peripheral surface 1a of the first roller 1 becomes shorter). The rear inclined surface 23 becomes lower as it advances from the top 21a in the direction opposite to the first roller rotation direction.

前方傾斜面22は、打ち抜き加工を行う際、頂部21aから第１ローラ回転方向前方に向かって順にワークAと接触するように、第１ローラ1および第２ローラ2の半径、ワークAの厚さ等に応じて傾斜角度が設定されている。このため、前方傾斜面22の縁部22aうち、最も第１ローラ回転方向前方に位置する前端縁21bは、最も遅くワークAと接触することになる。また、後方傾斜面23は、打ち抜き加工を行う際、頂部21aから第１ローラ回転方向後方に向かって順にワークAと接触するように、第1ローラ1および第２ローラ2の半径、ワークAの厚さ等に応じて傾斜角度が設定されている。このため、後方傾斜面23の縁部23aのうち、最も第１ローラ回転方向後方に位置する後端縁21cは、最も遅くワークAと接触することとなる。   The front inclined surface 22 has a radius of the first roller 1 and the second roller 2 and a thickness of the work A so that the front inclined surface 22 contacts the work A in order from the top 21a toward the front in the first roller rotation direction. The inclination angle is set according to the above. For this reason, among the edge portions 22a of the front inclined surface 22, the front end edge 21b that is located most forward in the first roller rotation direction comes into contact with the workpiece A the latest. In addition, the rear inclined surface 23 is configured so that the radius of the first roller 1 and the second roller 2 and the workpiece A are in contact with the workpiece A in order from the top 21a toward the rear in the first roller rotation direction when punching is performed. The inclination angle is set according to the thickness and the like. For this reason, among the edge portions 23 a of the rear inclined surface 23, the rear end edge 21 c that is located most rearward in the first roller rotation direction comes into contact with the workpiece A the latest.

頂部21aの高さは、打ち抜き刃3に必要な剪断力が得られるような高さに設定されている。このため、頂部21aは、先端が平坦な従来の打ち抜き刃の高さよりも高く形成されている。そして、前端縁21bの高さは、従来の打ち抜き刃の高さよりも低く形成されている。また、後方傾斜面23の縁部23aのうち、最も第１ローラ回転方向後方に位置する後端縁21cの高さは、前端縁21bよりも若干低く形成されている。
つまり、実施例１の打ち抜き刃3は、まず初めに頂部21aがワークAと接した後、第１ローラ1の回転が進むにつれて前方傾斜面22が頂部21aから前端縁21bに向かって順に後述する第２ローラ2の打ち抜き穴3内に進入し、その後、後方傾斜面23が頂部21aから後端縁21cに向かって打ち抜き穴3内に進入することで、打ち抜き刃3の縁部22a,23aと打ち抜き穴6の開口縁との剪断力によりワークAを切断して行き、最終的に後端縁21cが打ち抜き穴6に進入することで打ち抜きが完了する。
打ち抜き刃3を上記のような形状とすることにより、従来の平坦な打ち抜き刃に比べて、第１ローラ1と第２ローラ2のクリアランスをより狭くできるため、ワークAにバリの発生をより小さなものとすることができる。 The height of the top portion 21a is set to such a height that a shearing force necessary for the punching blade 3 can be obtained. For this reason, the top portion 21a is formed higher than the height of a conventional punching blade having a flat tip. The height of the front end edge 21b is formed lower than the height of the conventional punching blade. Further, the height of the rear end edge 21c located most rearward in the first roller rotation direction in the edge portion 23a of the rear inclined surface 23 is formed slightly lower than the front end edge 21b.
That is, in the punching blade 3 of the first embodiment, after the top portion 21a first comes into contact with the workpiece A, the front inclined surface 22 is described later in order from the top portion 21a toward the front edge 21b as the rotation of the first roller 1 proceeds. After entering the punching hole 3 of the second roller 2, the rear inclined surface 23 enters the punching hole 3 from the top part 21a toward the rear edge 21c, so that the edges 22a and 23a of the punching blade 3 The workpiece A is cut by a shearing force with the opening edge of the punching hole 6 and finally the trailing edge 21c enters the punching hole 6 to complete the punching.
By forming the punching blade 3 as described above, the clearance between the first roller 1 and the second roller 2 can be made narrower than that of the conventional flat punching blade. Can be.

第１ローラ1の外周面1bにおいて、打ち抜き刃3の軸方向両外側には、位置決め用の複数のパイロット31が放射状に突出している。パイロット31は打ち抜き刃3の位置に対応して周方向に22.5°ピッチで16個配置されている。パイロット31の外周面1bからの突出量は、打ち抜き刃3の外周面1bからの突出量よりも長く設定されている。パイロット31の先端は、略半球状に形成されている。   On the outer peripheral surface 1 b of the first roller 1, a plurality of positioning pilots 31 protrude radially from both axial outer sides of the punching blade 3. Sixteen pilots 31 are arranged at a pitch of 22.5 ° in the circumferential direction corresponding to the position of the punching blade 3. The amount of protrusion of the pilot 31 from the outer peripheral surface 1b is set longer than the amount of protrusion of the punching blade 3 from the outer peripheral surface 1b. The tip of the pilot 31 is formed in a substantially hemispherical shape.

第２ローラ2は、円筒状に形成され、回転軸O2周りに回動可能に支持されている。回転軸O2は、第１ローラ1の回転軸O1と平行である。また、第１ローラ1と第２ローラ2は、両ローラ1,2間にワークAを挟み込んだ状態でそれぞれの外周面1b,2bがワークAと接するように配置されている。第２ローラ2の一端には、第１ローラ1側の第１ギア1aと噛み合う第２ギア2aが連結されている。第２ギア2aは第１ギア1aと同一形状の歯車である。よって、電動モータを駆動したとき、第１ローラ1と第２ローラ2は、互いに逆方向に同一の角速度で回転する。   The second roller 2 is formed in a cylindrical shape and is supported so as to be rotatable around the rotation axis O2. The rotation axis O2 is parallel to the rotation axis O1 of the first roller 1. Further, the first roller 1 and the second roller 2 are arranged so that the outer peripheral surfaces 1b and 2b are in contact with the workpiece A in a state where the workpiece A is sandwiched between the rollers 1 and 2. One end of the second roller 2 is connected to a second gear 2a that meshes with the first gear 1a on the first roller 1 side. The second gear 2a is a gear having the same shape as the first gear 1a. Thus, when the electric motor is driven, the first roller 1 and the second roller 2 rotate at the same angular velocity in opposite directions.

第２ローラ2の外周面2bには、ワークAの打ち抜き用の雌型となる複数の打ち抜き穴6が放射状に形成されている。打ち抜き穴6は、第２ローラ2の外周面2bから内周面2cに至る貫通穴である。打ち抜き穴6は、上述した打ち抜き刃3と対応する位置に配置されている。すなわち、打ち抜き穴6は、周方向に22.5°ピッチで16個並んだものが第２ローラ2の軸方向に5列配置されている。１つの列の打ち抜き穴6は、隣接する打ち抜き穴6に対し、周方向位置が11.25°ずれている。打ち抜き穴6は、打ち抜き刃3の外径よりも大きな内径を有する平面視円形状に形成されている。
第２ローラ2において、打ち抜き穴6の第２ローラ軸方向両側には、位置決め用の複数の位置決め穴32が放射状に形成されている。位置決め穴32はパイロット31の位置に対応して周方向に22.5°ピッチで16個配置されている。打ち抜き加工装置の駆動時、周方向に複数配置したパイロット31のうちのいずれかは常に対応する位置決め穴32内に挿入された状態となる。 On the outer peripheral surface 2b of the second roller 2, a plurality of punching holes 6 serving as female dies for punching the workpiece A are formed radially. The punching hole 6 is a through hole extending from the outer peripheral surface 2b of the second roller 2 to the inner peripheral surface 2c. The punching hole 6 is disposed at a position corresponding to the punching blade 3 described above. That is, 16 punched holes 6 arranged in a circumferential direction at a pitch of 22.5 ° are arranged in five rows in the axial direction of the second roller 2. The perforation holes 6 in one row are offset by 11.25 ° in the circumferential direction with respect to the adjacent punch holes 6. The punching hole 6 is formed in a circular shape in plan view having an inner diameter larger than the outer diameter of the punching blade 3.
In the second roller 2, a plurality of positioning holes 32 for positioning are formed radially on both sides of the punching hole 6 in the second roller axial direction. Sixteen positioning holes 32 are arranged at a pitch of 22.5 ° in the circumferential direction corresponding to the position of the pilot 31. When the punching device is driven, one of the pilots 31 arranged in the circumferential direction is always inserted into the corresponding positioning hole 32.

［打ち抜き刃の取り付け構造］
次に、第１ローラ1に対する打ち抜き刃3の取り付け構造を説明する。
第１ローラ1には、各打ち抜き刃3と対応する位置に第１ローラ1の外周面1bから内周面1cに至る貫通穴7が放射状に形成されている。
各貫通穴7には、打ち抜き刃3が先端8aに設けられた胴部8と、この胴部8の打ち抜き刃3と反対側の端部8bに設けられた頭部9とを有するボルト型部材10が、第１ローラ1の内側から貫通穴7に挿通されている。胴部8は貫通穴7よりも小径の円筒状に形成され、頭部9は貫通穴7よりも大径に形成されている。胴部8の長さは、頭部9が第１ローラ1の内周面1cと当接した状態で、外周面1bよりも径方向外側に規定の長さだけ突出するように設定されている。
第１ローラ1の内部には、頭部9の上面9aと当接する外周面11aを有する環状のカラー（軸方向移動規制部材）11が設けられている。このカラー11により、頭部9の第１ローラ1の内側への移動が規制されることで、ボルト型部材10の軸方向移動が規制される。 [Punching blade mounting structure]
Next, a structure for attaching the punching blade 3 to the first roller 1 will be described.
In the first roller 1, through holes 7 extending from the outer peripheral surface 1 b of the first roller 1 to the inner peripheral surface 1 c are formed radially at positions corresponding to the punching blades 3.
Each through-hole 7 is a bolt-type member having a barrel portion 8 provided with a punching blade 3 at a tip 8a and a head portion 9 provided at an end portion 8b opposite to the punching blade 3 of the barrel portion 8. 10 is inserted into the through hole 7 from the inside of the first roller 1. The body portion 8 is formed in a cylindrical shape having a smaller diameter than the through hole 7, and the head portion 9 is formed in a larger diameter than the through hole 7. The length of the body portion 8 is set so as to protrude by a predetermined length radially outward from the outer peripheral surface 1b in a state where the head 9 is in contact with the inner peripheral surface 1c of the first roller 1. .
Inside the first roller 1, an annular collar (axial movement restricting member) 11 having an outer peripheral surface 11a in contact with the upper surface 9a of the head 9 is provided. The collar 11 restricts the movement of the head 9 in the first roller 1, thereby restricting the axial movement of the bolt-type member 10.

図３、図４に示すように、各ボルト型部材10の頭部9の側面には、頭部9の一部を切り欠いた平面部9bが形成されている。この平面部9bの方向（向き）は、打ち抜き刃3の向く方向（向き）を適正に配置した状態で、第１ローラ1の軸方向と直交するように設定されている。
そして、隣接するボルト型部材10,10の頭部9,9の間には、リング（回転規制部材）12が介装されている。このリング12は、一方の側面12aが頭部9の平面部9bと面接触し、他方の側面12bが隣接する頭部9と線接触することで、自らの第１ローラ軸方向への移動が規制され、これにより、ボルト型部材10の回転を規制している。 As shown in FIGS. 3 and 4, a flat portion 9 b in which a part of the head 9 is cut out is formed on the side surface of the head 9 of each bolt-type member 10. The direction (orientation) of the flat surface portion 9b is set to be orthogonal to the axial direction of the first roller 1 with the direction (orientation) of the punching blade 3 facing properly.
A ring (rotation restricting member) 12 is interposed between the heads 9 and 9 of the adjacent bolt-type members 10 and 10. The ring 12 has one side surface 12a in surface contact with the flat portion 9b of the head 9, and the other side surface 12b in line contact with the adjacent head 9 so that the ring 12 can move in the first roller axial direction. This restricts the rotation of the bolt type member 10.

ここで、第１ローラ1に対するパイロット31の取り付け構造については、上記第１ローラ1に対する打ち抜き刃3の取り付け構造と同様である。すなわち、第１ローラ1には、各パイロット31と対応する位置に第１ローラ1の外周面1bから内周面1cに至るパイロット用穴33が放射状に形成され、上述したボルト型部材10と胴部の先端を除いて同一形状のボルト型部材10'が内周面1cから挿通され、ボルト型部材10'の先端にパイロット31が形成されている。ボルト型部材10'の軸方向移動はボルト型部材10と同様、カラー11により規制される。なお、パイロット31の先端に方向性はない、つまり、パイロット31の先端は円対称形状であるため、ボルト型部材10'の回転をリング12で規制する必要はない。   Here, the attachment structure of the pilot 31 to the first roller 1 is the same as the attachment structure of the punching blade 3 to the first roller 1. That is, pilot holes 33 extending from the outer peripheral surface 1b to the inner peripheral surface 1c of the first roller 1 are formed in the first roller 1 at positions corresponding to the respective pilots 31, and the bolt-type member 10 and the body described above are formed. A bolt-shaped member 10 ′ having the same shape except for the tip of the portion is inserted from the inner peripheral surface 1c, and a pilot 31 is formed at the tip of the bolt-shaped member 10 ′. The axial movement of the bolt-shaped member 10 ′ is regulated by the collar 11, similar to the bolt-shaped member 10. Note that the tip of the pilot 31 has no directionality, that is, the tip of the pilot 31 has a circularly symmetric shape, and therefore it is not necessary to restrict the rotation of the bolt-type member 10 ′ with the ring 12.

次に、実施例１の作用を説明する。
［打ち抜き加工方法］
図１において、図外の電動モータを駆動すると、両ローラ1,2は互いに逆方向に同一速度で回転する。両ローラ1,2間にワークAを送り込むと、両ローラ1,2に挟まれたワークAは、両ローラ1,2の外周面1b,2bの周速と同一速度で移送方向に送り出される。ワークAが両ローラ1,2間を通過する際、第１ローラ1の打ち抜き刃3が第２ローラ2の打ち抜き穴6に進入することでワークAの一部が打ち抜き刃3および打ち抜き穴6の形状に対応した円形状に切り抜かれ、千鳥状に並んだ開口を有する金属箔が得られる。 Next, the operation of the first embodiment will be described.
[Punching method]
In FIG. 1, when an electric motor (not shown) is driven, both rollers 1 and 2 rotate in the opposite directions at the same speed. When the workpiece A is fed between the rollers 1 and 2, the workpiece A sandwiched between the rollers 1 and 2 is fed in the transfer direction at the same speed as the circumferential speed of the outer peripheral surfaces 1b and 2b of the rollers 1 and 2. When the workpiece A passes between the rollers 1 and 2, the punching blade 3 of the first roller 1 enters the punching hole 6 of the second roller 2 so that a part of the workpiece A is removed from the punching blade 3 and the punching hole 6. A metal foil having openings that are cut out in a circular shape corresponding to the shape and arranged in a staggered pattern is obtained.

［打ち抜き刃の組み付け方法］
実施例１の第１ローラ1に対する打ち抜き刃3の組み付け方法を説明する。
作業者は、第１ローラ1の軸方向を上下にした状態で、最も下側に位置する列の各ボルト型部材10'を各パイロット用穴33に挿通させ、続いて、最も下側に位置する列の各ボルト型部材10を貫通穴7に挿通させ、各打ち抜き刃3の方向を適正に配置した状態で、カラー11を取り付ける。
上記のようにボルト型部材10とカラー11とを交互に取り付け、最後の最も上側に位置する列の各ボルト型部材10'のパイロット用穴33への挿通が終了した後、第１ローラ1の内部にカラー11を嵌め込むことで、第１ローラ1に対する打ち抜き刃3およびパイロットの組み付け作業が完了する。 [Assembly method of punching blade]
A method for assembling the punching blade 3 with respect to the first roller 1 according to the first embodiment will be described.
With the axial direction of the first roller 1 up and down, the operator inserts each bolt-type member 10 'in the lowermost row into each pilot hole 33, and then places it in the lowermost position. Each of the bolt-type members 10 of the row to be inserted is inserted into the through hole 7, and the collar 11 is attached in a state where the directions of the punching blades 3 are appropriately arranged.
As described above, the bolt-type members 10 and the collars 11 are alternately attached, and after the insertion of the bolt-type members 10 ′ in the last uppermost row into the pilot holes 33 is completed, the first roller 1 By fitting the collar 11 inside, the assembly operation of the punching blade 3 and the pilot with respect to the first roller 1 is completed.

［組み付け性向上作用］
実施例１の打ち抜き加工装置では、第１ローラ1を円筒状として貫通穴7を形成し、貫通穴7の内側から頭部9が第１ローラ1の内周面1cと接触した状態まで挿通したボルト型部材10の胴部8の先端8aに打ち抜き刃3を形成し、ボルト型部材10の頭部9にカラー11の外周面11aを当接させてボルト型部材10の軸方向移動を規制した。よって、打ち抜き刃3の外周面1bに対する突出量は、第１ローラ1の外周面1bと内周面1cとの間の距離、すなわち第１ローラ1の肉厚と、ボルト型部材10の胴部8の長さとから決まる。ここで、両者の寸法は、あらかじめ精度良く加工することが可能であるから、実施例１の打ち抜き加工装置によれば、各打ち抜き刃3を取り付ける際の突出量の調整を省略できる。よって、突出量を計測しながら第１ローラの外周面に打ち抜き刃をねじ込む従来装置に比して、打ち抜き刃の組み付けに要する工数を大幅に低減できる。 [Assembly improvement]
In the punching apparatus according to the first embodiment, the first roller 1 is cylindrical and the through hole 7 is formed, and the head 9 is inserted from the inside of the through hole 7 to a state where the head 9 is in contact with the inner peripheral surface 1c of the first roller 1. A punching blade 3 is formed at the tip 8a of the body 8 of the bolt-type member 10, and the outer peripheral surface 11a of the collar 11 is brought into contact with the head 9 of the bolt-type member 10 to restrict the axial movement of the bolt-type member 10. . Therefore, the protrusion amount of the punching blade 3 with respect to the outer peripheral surface 1b is the distance between the outer peripheral surface 1b of the first roller 1 and the inner peripheral surface 1c, that is, the thickness of the first roller 1 and the body portion of the bolt-shaped member 10. Determined by the length of 8. Here, since both dimensions can be processed with high accuracy in advance, according to the punching apparatus of the first embodiment, adjustment of the protruding amount when each punching blade 3 is attached can be omitted. Therefore, compared with the conventional apparatus which screws a punching blade into the outer peripheral surface of a 1st roller, measuring the protrusion amount, the man-hour required for the assembly of a punching blade can be reduced significantly.

また、各ボルト型部材10は、貫通穴7を貫通不能な頭部9を有するため、組み付け時に固定のための作業を行うことなく第１ボルト型部材10の第１ローラ径方向外側への抜けを確実に防止できる。さらに、各ボルト部材10の第１ローラ径方向内側への抜けは、１つのカラー11によって確実に防止できる。このカラー11は、各ボルト型部材10の胴部8を貫通穴7に挿通させた後に第１ローラ1の内部に嵌め込むだけであるため、工数を要しない。   Further, each bolt-type member 10 has a head 9 that cannot penetrate the through-hole 7, so that the first bolt-type member 10 can be pulled out to the outside in the first roller radial direction without performing a fixing operation at the time of assembly. Can be reliably prevented. Further, the one collar 11 can reliably prevent the bolt members 10 from coming out inward in the first roller radial direction. Since the collar 11 is only fitted into the first roller 1 after the body portion 8 of each bolt-type member 10 is inserted into the through hole 7, no man-hour is required.

［打ち抜き刃の回転防止作用］
実施例１では、打ち抜き刃3の形状を第１ローラ回転方向に対して前後非対称形状としているため、ボルト型部材10が回転しての方向が変わってしまうと、打ち抜き刃3と打ち抜き穴6との干渉等が生じると共に、打ち抜き刃3の各部のワークAに対する接触順序が不適正となるため、ワークAに適正な開口が形成されず、開口に形成されるバリが大きくなってしまう。
そこで、実施例１では、ボルト型部材10の頭部9に第１ローラ1の軸方向と直交する平面部9bを形成し、平面部9bと当接するリング12を隣接する一対の頭部9,9間に配置したため、ボルト型部材10の回転が規制されて打ち抜き刃3の適正な方向が確保される。さらに、１つのリング12を取り付ける際、ボルト型部材10の方向が適正な方向から多少ずれていたとしても、リング12によって適正な方向に強制されると共に、同列の16個の打ち抜き刃3の回転規制を実現でき、組み付け性に優れる。 [Punching blade rotation prevention action]
In the first embodiment, since the shape of the punching blade 3 is asymmetrical with respect to the first roller rotation direction, if the direction of rotation of the bolt-shaped member 10 changes, the punching blade 3 and the punching hole 6 In addition, the contact order of each part of the punching blade 3 with respect to the workpiece A becomes inappropriate, so that an appropriate opening is not formed in the workpiece A, and the burr formed in the opening becomes large.
Therefore, in the first embodiment, a flat portion 9b perpendicular to the axial direction of the first roller 1 is formed on the head portion 9 of the bolt-type member 10, and the ring 12 that contacts the flat portion 9b is connected to a pair of adjacent head portions 9, Since it is arranged between 9, the rotation of the bolt-shaped member 10 is restricted, and an appropriate direction of the punching blade 3 is ensured. Further, when one ring 12 is attached, even if the direction of the bolt-shaped member 10 is slightly deviated from the proper direction, the ring 12 is forced to the proper direction and the 16 punching blades 3 in the same row are rotated. It can realize regulations and has excellent assemblability.

［同期補償作用］
実施例１の打ち抜き加工装置では、第１ローラ1の第１ギア1aと第２ローラ2の第２ギア2aとの噛み合いによって両ローラ1,2を同期回転させているため、打ち抜き刃3と打ち抜き穴6との同期は両ギア1a,2aに依存しているため、打ち抜き刃3と打ち抜き穴6との位相ずれが生じやすい。位相ずれが生じると、打ち抜き刃3が打ち抜き穴6の縁部と干渉し、打ち抜き加工が適正に行われなくなると共に打ち抜き刃3の耐久性低下を招いてしまう。 [Synchronization compensation]
In the punching apparatus according to the first embodiment, the rollers 1 and 2 are synchronously rotated by meshing between the first gear 1a of the first roller 1 and the second gear 2a of the second roller 2, so that the punching blade 3 and the punching blade 3 are punched. Since synchronization with the hole 6 depends on both the gears 1a and 2a, a phase shift between the punching blade 3 and the punching hole 6 is likely to occur. When the phase shift occurs, the punching blade 3 interferes with the edge of the punching hole 6, and the punching process is not performed properly and the durability of the punching blade 3 is reduced.

これに対し、実施例１では、パイロット31と位置決め穴32とによる同期補償機構を設けた。パイロット31は、打ち抜き刃3よりも第１ローラ1の外周面1bからの突出量が長いため、同列の打ち抜き刃3が打ち抜き穴6に挿入されるタイミングよりも早いタイミングで位置決め穴32に挿入し、同列の打ち抜き刃3が打ち抜き穴6から離間するタイミングよりも遅いタイミング位置決め穴32から離間する。そして、打ち抜き加工装置の駆動時には、第１ロール1の周方向に複数設けたパイロット31のうち、いずれかのパイロット31は第２ローラ2に設けた位置決め穴32に挿通された状態となる。このため、第１ローラ1と第２ローラ2との間で位相ずれを生じさせるような力が作用したとしても、パイロット31と位置決め穴32の内周面との干渉によって位相ずれが生じるのを回避でき、打ち抜き刃3と打ち抜き穴6の位相を適正に維持できる。   On the other hand, in the first embodiment, a synchronization compensation mechanism using the pilot 31 and the positioning hole 32 is provided. Since the protrusion amount of the pilot 31 from the outer peripheral surface 1b of the first roller 1 is longer than that of the punching blade 3, the pilot 31 is inserted into the positioning hole 32 at a timing earlier than the timing at which the punching blade 3 in the same row is inserted into the punching hole 6. The punching blades 3 in the same row are separated from the timing positioning holes 32 later than the timing at which the punching blades 3 are separated from the punching holes 6. When the punching apparatus is driven, one of the pilots 31 provided in the circumferential direction of the first roll 1 is inserted into the positioning hole 32 provided in the second roller 2. For this reason, even if a force causing a phase shift acts between the first roller 1 and the second roller 2, the phase shift is caused by the interference between the pilot 31 and the inner peripheral surface of the positioning hole 32. The phase of the punching blade 3 and the punching hole 6 can be properly maintained.

実施例１の効果を列挙する。
(1) 第１ローラ1を円筒状として貫通穴7を形成し、打ち抜き刃3が先端8aに設けられ貫通穴7を貫通可能な胴部8と、この胴部8の打ち抜き刃3と反対側の端部8bに設けられ貫通穴7を貫通不能な頭部9とを有し、第１ローラ1の内側から頭部9が第１ローラ1の内周面1cと接触した状態で貫通穴7に挿通されたボルト型部材10と、頭部9と当接しボルト型部材10の軸方向移動を規制する軸方向移動規制部材と、を設けた。これにより、打ち抜き刃3を第１ローラ1に組み付ける際、打ち抜き刃3の突出量の調整が不要となり、打ち抜き刃3の組み付け性の向上を図ることができる。
(2) 軸方向移動規制部材を、ボルト型部材10よりも第１ローラ1の径方向内側に位置し、頭部9の第１ローラ1の径方向内側への移動を規制する環状のカラー11としたため、１つのカラー11を取り付けるだけで全てのボルト型部材10の第１ローラ径方向内側への抜けを防止でき、打ち抜き刃3の組み付け性をより高めることができる。 The effects of Example 1 are listed.
(1) The first roller 1 is formed in a cylindrical shape to form a through-hole 7, a punching blade 3 is provided at the tip 8a, and a barrel 8 that can penetrate the through-hole 7, and the barrel 8 opposite to the punching blade 3 The head 9 is provided at the end 8b of the first roller 1 and cannot pass through the through hole 7. The through hole 7 is in contact with the inner peripheral surface 1c of the first roller 1 from the inside of the first roller 1. And a bolt type member 10 inserted through the head 9 and an axial movement restricting member that abuts the head 9 and restricts the axial movement of the bolt type member 10. Thereby, when the punching blade 3 is assembled to the first roller 1, it is not necessary to adjust the protruding amount of the punching blade 3, and the assembling property of the punching blade 3 can be improved.
(2) An annular collar 11 is located on the radially inner side of the first roller 1 with respect to the bolt-shaped member 10 so as to restrict the movement of the head 9 toward the radially inner side of the first roller 1 with respect to the axial movement restricting member. Therefore, it is possible to prevent all the bolt-shaped members 10 from coming out inward in the first roller radial direction by simply attaching one collar 11, and to improve the assembling property of the punching blade 3.

(3) ボルト型部材10の回転を規制する回転規制部材を設けたため、打ち抜き刃3の適正な方向を維持でき、打ち抜き加工装置の加工品質を維持できる。
(4) 頭部9に第１ローラ1の軸方向と直交する平面部9bを形成し、回転規制部材を、隣接する一対の頭部9,9間に介装され、その側面12aが平面部9bと当接するリング12としたため、ボルト型部材10の組み付け時にボルト型部材10の方向に多少の誤差があったとしても、リング12を組み付けるだけで自動的に適正な方向に修正できる。さらに同列（第１ローラ1の軸方向同一位置）に並ぶ16個の打ち抜き刃3の回転規制を１つのリング12で実現でき、打ち抜き刃3の組み付け性をより高めることができる。よって、ワークAをバリの無い製品とするために前後非対称形状とした打ち抜き刃3の組み付けが容易になる。 (3) Since the rotation restricting member for restricting the rotation of the bolt type member 10 is provided, the proper direction of the punching blade 3 can be maintained, and the processing quality of the punching apparatus can be maintained.
(4) A flat portion 9b perpendicular to the axial direction of the first roller 1 is formed on the head 9 and a rotation restricting member is interposed between a pair of adjacent heads 9 and 9, and the side surface 12a is a flat portion. Since the ring 12 is in contact with 9b, even if there is a slight error in the direction of the bolt-type member 10 when the bolt-type member 10 is assembled, it can be automatically corrected to the proper direction by simply assembling the ring 12. Further, the rotation restriction of the 16 punching blades 3 arranged in the same row (the same position in the axial direction of the first roller 1) can be realized by one ring 12, and the assembling property of the punching blades 3 can be further improved. Therefore, it is easy to assemble the punching blade 3 having an asymmetrical shape in order to make the workpiece A a product without burrs.
