Description

本発明は、金型を用いて薄板材に対し予め設定した打抜き加工を行う薄板材の打抜き装置及びその打抜き方法に関する。   The present invention relates to a thin plate material punching apparatus that performs a preset punching process on a thin plate material using a mold and a punching method thereof.

複数の鉄心片を積層して構成される積層鉄心のモータ性能を向上させるため、鉄損の低減を目的とした鉄心片の薄板化が進んでいる。
また、コスト削減のため、材料（条材）から鉄心片を打抜く際の板取りのレイアウトについても、鉄心片（製品）の多列取りや、鉄心片の打抜き後のスクラップ幅の最小化を行うことで、歩留りの向上を図ることが求められている。
上記した材料からの鉄心片の打抜きは、金型を用いて行っている。なお、材料の搬送時における金型内での材料の持上げは、金型内に配置された材料の下方に設けられたリフターを用いて行っている（例えば、特許文献１参照）。 In order to improve the motor performance of a laminated core constituted by laminating a plurality of iron core pieces, the thickness of the iron core pieces has been reduced for the purpose of reducing iron loss.
In addition, to reduce costs, the layout of plate cutting when punching core pieces from materials (strips) is also reduced, with multiple rows of core pieces (products) and minimizing the scrap width after punching the core pieces. By doing so, it is required to improve the yield.
The punching of the iron core piece from the above material is performed using a mold. In addition, lifting of the material in the metal mold | die at the time of conveyance of material is performed using the lifter provided below the material arrange | positioned in a metal mold | die (for example, refer patent document 1).

特開２０１３−１０７１１６号公報JP 2013-107116 A

しかしながら、材料が薄板化することにより、材料の剛性が低下するため、鉄心片打抜き後のスクラップ部の剛性が更に低くなる。その上、隣り合う鉄心片の打抜き箇所の幅が狭くなることで、材料の剛性が大きく低下する。
このように、材料の剛性が低くなると、材料が下方へ撓むだけでなく、搬送時における金型内での材料のバタツキが大きくなり、材料が金型に引っかかり易くなるという問題がある。また、この問題を解消するため、リフターの設置数を増やすことも考えられるが、設置数を増やそうにも、レイアウト上、リフターの設置可能な場所が限られており、材料の撓みやバタツキが大きい箇所に、リフターを配置できないという問題もある。
従って、材料の撓みやバタツキを抑制するため、材料の送り速度を遅くして、鉄心片の打抜き加工を行う必要があり、生産性の低下を招いていた。 However, since the rigidity of the material is reduced as the material is thinned, the rigidity of the scrap portion after punching the iron core piece is further reduced. In addition, the rigidity of the material is greatly reduced by reducing the width of the punched portion of the adjacent iron core pieces.
Thus, when the rigidity of the material is lowered, there is a problem that the material not only bends downward, but also the material flutters in the mold during conveyance increases, and the material is easily caught on the mold. In order to solve this problem, it may be possible to increase the number of lifters installed. However, in order to increase the number of installations, the locations where lifters can be installed are limited due to the layout, and material deflection and fluttering are large. There is also a problem that the lifter cannot be placed at the location.
Therefore, in order to suppress bending and fluttering of the material, it is necessary to perform the punching process of the iron core piece by slowing the feed rate of the material, resulting in a decrease in productivity.

本発明はかかる事情に鑑みてなされたもので、生産性を低下させることなく、安定した打抜き加工を実施可能な薄板材の打抜き装置及びその打抜き方法を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a thin plate material punching apparatus and a punching method thereof capable of performing stable punching without reducing productivity.

続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
図１〜図３に示すように、本発明の第１の実施の形態に係る薄板材の打抜き装置（以下、単に打抜き装置ともいう）１０は、下型１１と上型１２を備える金型１３を有し、この金型１３を用いて、薄板材（薄板条材）１４に対し予め設定した打抜き加工を行う装置であり、金型１３には、薄板材１４を持上げ可能なリフト機構１５が設けられている。 Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
As shown in FIGS. 1 to 3, a sheet metal punching device (hereinafter also simply referred to as a punching device) 10 according to a first embodiment of the present invention is a mold 13 including a lower die 11 and an upper die 12. The die 13 is used to perform a preset punching process on a thin plate material (thin plate strip material) 14. The mold 13 has a lift mechanism 15 that can lift the thin plate material 14. Is provided.

以下、第１の実施の形態に係る薄板材の打抜き装置１０を、固定子（ステータ）からなる積層鉄心の製造に適用した場合について説明する。なお、積層鉄心は、回転子（ロータ）でもよい。
ここで、打抜き対象となる薄板材１４は、厚みが、例えば、０．１０〜０．５ｍｍ程度の電磁鋼板やアモルファス等からなるものであるが、薄板材の厚みが薄いほど（０．２ｍｍ以下程度）、薄板材の剛性が低下し、薄板材が下方へ撓み易くなり、また、金型内での薄板材のバタツキが大きくなり、薄板材が金型に引っかかり易くなる傾向にある。 Hereinafter, the case where the sheet metal punching device 10 according to the first embodiment is applied to the manufacture of a laminated iron core made of a stator (stator) will be described. The laminated iron core may be a rotor (rotor).
Here, the thin plate material 14 to be punched is made of, for example, an electromagnetic steel plate or amorphous material having a thickness of about 0.10 to 0.5 mm. However, the thinner the thin plate material is (less than 0.2 mm). Degree), the rigidity of the thin plate material is lowered, the thin plate material is easily bent downward, and the flutter of the thin plate material in the mold is increased, so that the thin plate material tends to be easily caught on the mold.

図１（Ａ）に示すように、上型１２は下型１１に対し、ガイドロッド１６、１７に沿って昇降可能となっている。なお、上型１２と下型１１の間には、ストリッパー１８が配置されている。
図１〜図３に示すように、下型１１の上面には、薄板材１４の幅方向両側に配置され、薄板材１４を搬送方向にガイドする、断面逆Ｌ字状となった対となるガイドレール１９、２０が設けられている。また、上型１２の下部には、下型１１上の薄板材１４に対し、予め設定した形状（ここでは固定子を構成する鉄心片）の打抜き加工を行うパンチを支持するパンチプレート２１が設けられている。 As shown in FIG. 1A, the upper mold 12 can be moved up and down along the guide rods 16 and 17 with respect to the lower mold 11. A stripper 18 is disposed between the upper mold 12 and the lower mold 11.
As shown in FIGS. 1 to 3, the upper surface of the lower mold 11 is disposed on both sides in the width direction of the thin plate material 14, and becomes a pair having a reverse L-shaped cross section that guides the thin plate material 14 in the transport direction. Guide rails 19 and 20 are provided. In addition, a punch plate 21 that supports a punch for punching a thin plate material 14 on the lower mold 11 with a preset shape (here, an iron core piece constituting a stator) is provided at the lower part of the upper mold 12. It has been.

上型１２には、リフト機構１５が設けられている。このリフト機構１５は、対となる昇降ロッド（昇降手段の一例）２２、２３と、これに設けられた支持ロッド（支持部材の一例）２４を有している。
対となる昇降ロッド２２、２３は、鉛直方向に配置され、その上部が、上型１２の両側側部（金型１３の外部）に取付け固定されている。なお、昇降ロッドは、ストリッパーに取付け固定することもできる。
このように、各昇降ロッド２２、２３は、薄板材１４の幅方向の両側方の位置（平面視して薄板材１４と重ならない位置）に設けられている。 The upper mold 12 is provided with a lift mechanism 15. The lift mechanism 15 includes a pair of elevating rods (an example of elevating means) 22 and 23, and a support rod (an example of a supporting member) 24 provided thereon.
The pair of lifting rods 22 and 23 are arranged in the vertical direction, and upper portions thereof are attached and fixed to both side portions of the upper mold 12 (outside of the mold 13). The lifting rod can be attached and fixed to the stripper.
As described above, the elevating rods 22 and 23 are provided at positions on both sides in the width direction of the thin plate material 14 (positions that do not overlap the thin plate material 14 in plan view).

支持ロッド２４は、断面四角形（ここでは長方形）であり、薄板材１４の下方に水平配置され、その両端部が、昇降ロッド２２、２３の下部に取付け固定されている。なお、支持ロッド２４は、図３に示すように、平面視して薄板材１４に形成されたパイロット孔２５の位置を避けるように、部分的に折り曲げられているが、例えば、リフト機構の設置場所によって、直線状にすることもでき、また、平面視して波状やジグザグ状にすることもできる。
これにより、薄板材１４を下方から幅方向全体に渡って支持できる。 The support rod 24 has a quadrangular cross section (here, a rectangle), is horizontally disposed below the thin plate material 14, and both ends thereof are fixedly attached to the lower portions of the elevating rods 22 and 23. As shown in FIG. 3, the support rod 24 is partially bent so as to avoid the position of the pilot hole 25 formed in the thin plate member 14 in plan view. Depending on the location, it can be straight, or it can be wavy or zigzag in plan view.
Thereby, the thin plate material 14 can be supported over the whole width direction from the downward direction.

この支持ロッド２４と上記したガイドレール１９、２０は、平面視して直交して配置されているため、図１（Ｃ）、図２（Ｃ）、図３に示すように、各ガイドレール１９、２０を長さ方向で分断して、支持ロッド２４と各ガイドレール１９、２０との接触を防止している。
また、下型１１の幅方向（薄板材１４の搬送方向とは直交する方向）には、図１（Ｂ）、（Ｃ）に示すように、薄板材１４の打抜き時に支持ロッド２４を退避させる凹部２６が設けられている。なお、凹部２６の断面形状（輪郭形状）は、断面四角形となっているが、支持ロッド２４を収容できれば、例えば、断面Ｕ字状や断面Ｖ字状とすることもできる。 Since the support rod 24 and the above-described guide rails 19 and 20 are arranged orthogonally in a plan view, as shown in FIGS. 1C, 2C, and 3, each guide rail 19 is provided. , 20 are divided in the length direction to prevent contact between the support rod 24 and the guide rails 19 and 20.
Further, in the width direction of the lower mold 11 (direction perpendicular to the conveying direction of the thin plate material 14), as shown in FIGS. 1B and 1C, the support rod 24 is retracted when the thin plate material 14 is punched. A recess 26 is provided. In addition, although the cross-sectional shape (contour shape) of the recessed part 26 becomes a cross-sectional square shape, if the support rod 24 can be accommodated, it can also be set as a cross-sectional U shape or a cross-sectional V shape.

これにより、薄板材１４の搬送時、即ち金型１３による薄板材１４の打抜き停止時は、図１（Ａ）〜（Ｃ）に示すように、上型１２が待機位置にあるため、支持ロッド２４も昇降ロッド２２、２３によって上昇した位置を維持し、薄板材１４が持上げられた状態を維持する。即ち、支持ロッド２４は、常時は凹部２６の上方に位置している。
また、薄板材１４の搬送停止時、即ち金型１３による薄板材１４の打抜き時は、図２（Ａ）〜（Ｃ）に示すように、上型１２の下降に伴い、支持ロッド２４が昇降ロッド２２、２３によって凹部２６内まで下降して、薄板材１４を下型１１上に配置できる。なお、図３中の符号２７は、金型１３による薄板材１４の打抜き部分である。 Accordingly, when the thin plate material 14 is conveyed, that is, when the punching of the thin plate material 14 by the mold 13 is stopped, the upper die 12 is in the standby position as shown in FIGS. 24 also maintains the raised position by the lifting rods 22 and 23, and maintains the state in which the thin plate material 14 is lifted. That is, the support rod 24 is always positioned above the recess 26.
When the conveyance of the thin plate material 14 is stopped, that is, when the thin plate material 14 is punched by the mold 13, the support rod 24 moves up and down as the upper die 12 is lowered, as shown in FIGS. The thin plate member 14 can be placed on the lower mold 11 by being lowered into the recess 26 by the rods 22 and 23. In addition, the code | symbol 27 in FIG. 3 is the punching part of the thin plate material 14 by the metal mold | die 13. As shown in FIG.

なお、リフト機構は、上記構成に限定されるものではなく、以下の構成にすることもできる。
リフト機構の昇降手段を、例えば、油圧シリンダーや弾性部材（バネ材）で構成することもできる。これにより、リフト機構の支持部材の高さの位置調整を容易にできる。
また、リフト機構の支持部材の長さ方向中央部の断面積を、長さ方向両側部の断面積よりも大きくすることもできる。これにより、支持部材の長さ方向中央部の剛性を高め、薄板材を支持する際の支持部材の撓みを抑制、更には防止することができる。 In addition, a lift mechanism is not limited to the said structure, It can also be set as the following structures.
The lifting means of the lift mechanism can be constituted by, for example, a hydraulic cylinder or an elastic member (spring material). Thereby, the position adjustment of the height of the support member of the lift mechanism can be facilitated.
Moreover, the cross-sectional area of the longitudinal direction center part of the support member of a lift mechanism can also be made larger than the cross-sectional area of the length direction both sides. Thereby, the rigidity of the center part of the length direction of a supporting member can be improved, and the bending of the supporting member at the time of supporting a thin plate material can be suppressed, and can also be prevented.

そして、支持部材については、図４に示すように、断面円形の棒３０で構成することもでき、この場合、棒３０の周囲に、棒３０に対して回転可能な円筒状のローラ３１を設けることができる。これにより、たとえ薄板材１４がローラ３１に接触した状態で搬送されたとしても、ローラ３１が回転することで、ローラ３１と薄板材１４との接触による薄板材１４への傷の発生を防止できる。
更に、図５に示す本発明の第２の実施の形態に係る薄板材の打抜き装置のように、支持部材を、薄板材１４の進行方向の長さを長くした（幅広の）支持板３５とした場合、支持板３５が打抜き後の工程に進入してもよい。このように、幅広の支持板３５を用いることで、支持板３５の剛性が更に高められると共に、広範囲にわたって薄板材１４を安定に支持することができる。 As shown in FIG. 4, the support member can also be constituted by a rod 30 having a circular cross section. In this case, a cylindrical roller 31 that is rotatable with respect to the rod 30 is provided around the rod 30. be able to. Thereby, even if the thin plate material 14 is conveyed in a state of being in contact with the roller 31, the roller 31 rotates to prevent the thin plate material 14 from being damaged due to the contact between the roller 31 and the thin plate material 14. .
Further, like the thin plate material punching device according to the second embodiment of the present invention shown in FIG. 5, the support member is formed by extending the length of the thin plate material 14 in the traveling direction (wide) In this case, the support plate 35 may enter the process after punching. As described above, by using the wide support plate 35, the rigidity of the support plate 35 can be further increased, and the thin plate member 14 can be stably supported over a wide range.

また、図６に示す本発明の第３の実施の形態に係る薄板材の打抜き装置のように、薄板材１４の幅方向の両側方に設けられた昇降手段４０、４１にそれぞれ、支持部材４２、４３を設けることもできる。
この支持部材４２、４３はそれぞれ、平面視して三角形の支持板４４と、その先端部に設けられた支持棒４５で構成され、薄板材１４の幅方向両側のみを支持する構成となっている。なお、対向する支持部材４２、４３（支持板４４）の上流側は、その間隔を薄板材１４の搬送方向に向けて徐々に狭くしている。
このように、支持部材４２、４３の輪郭形状を、平面視してＹ字状とすることで、打抜き部分２７を避けながら、薄板材１４をより安定に支持できる。 Further, like the thin plate material punching device according to the third embodiment of the present invention shown in FIG. 6, the support members 42 are respectively provided on the lifting means 40 and 41 provided on both sides in the width direction of the thin plate material 14. 43 can also be provided.
Each of the support members 42 and 43 is configured by a triangular support plate 44 in plan view and a support bar 45 provided at the tip thereof, and supports only both sides in the width direction of the thin plate material 14. . It should be noted that the upstream side of the opposing support members 42 and 43 (support plate 44) is gradually narrowed toward the conveying direction of the thin plate material 14.
Thus, the thin plate member 14 can be supported more stably while avoiding the punched portion 27 by making the contour shape of the support members 42 and 43 Y-shaped in plan view.

なお、上記した支持ロッド２４や支持部材４２（支持部材４３も同様）の代わりに、例えば、以下の作用効果を発揮可能な支持部材を使用することもできる。
１）支持部材に斜面や切欠き等を設けることで、撓んだ薄板材を支持した状態で搬送する際に、支持部材が薄板材に引っ掛かることなく、支持部材を滑らかに搬送できる。
２）支持部材の断面積を大きくすることで、支持部材の剛性を高めることができる。
３）支持部材の剛性が十分であれば、幅狭の方が支持部材を退避させる凹部（例えば、凹部２６）の内幅を狭くでき、金型の幅が狭い部分にもリフト機構を設けることができる。
４）支持部材の高さが低い（断面積が小さい）方が、小さな力で薄板材を支える（持ち上げる）ことができるので、昇降手段のバネやシリンダー等も小さくできる。これにより、製造コストを低減できると共に、設置スペースを狭くでき、更に、支持部材を退避させる凹部（例えば、凹部２６）の深さも浅くできるので、構造や加工が容易になる。 In addition, instead of the support rod 24 and the support member 42 described above (the same applies to the support member 43), for example, a support member capable of exhibiting the following effects can be used.
1) By providing the support member with an inclined surface, a notch or the like, the support member can be smoothly transported without being caught by the thin plate material when transported while supporting the bent thin plate material.
2) The rigidity of the support member can be increased by increasing the cross-sectional area of the support member.
3) If the rigidity of the support member is sufficient, the narrower one can narrow the inner width of the recess (for example, the recess 26) for retracting the support member, and a lift mechanism is also provided in the narrow part of the mold. Can do.
4) The lower the height of the support member (the smaller the cross-sectional area) can support (lift) the thin plate material with a smaller force, and therefore the springs and cylinders of the lifting means can be made smaller. As a result, the manufacturing cost can be reduced, the installation space can be narrowed, and the depth of the concave portion (for example, the concave portion 26) for retracting the support member can be reduced, so that the structure and processing are facilitated.

上記した作用効果を発揮可能な支持部材の選択は、リフト機構の設置場所（その部分での薄板材の剛性）や金型の仕様等によって、適宜行う。
この支持部材としては、その側断面形状が、例えば、図７（Ａ）〜（Ｋ）に示す支持部材５０〜６０がある。
図７（Ａ）は、正三角形の支持部材５０であり、上記した１）の作用効果がある。
図７（Ｂ）は、頂角が鈍角となった二等辺三角形を、薄板材１４の搬送方向に対して斜めに傾けた支持部材５１であり、上記した１）の作用効果を、上記した支持部材５０よりも高めることができる。
図７（Ｃ）は、頂角が鋭角となった二等辺三角形の支持部材５２である。これにより、上記した３）の作用効果が得られると共に、幅狭になって剛性が低下した分、その高さを高くして断面積を大きくすることで剛性を維持している（上記した２）の作用効果）。 The selection of the support member capable of exhibiting the above-described effects is appropriately performed according to the installation location of the lift mechanism (the rigidity of the thin plate material at that portion), the specifications of the mold, and the like.
As this support member, the side cross-sectional shape includes, for example, support members 50 to 60 shown in FIGS.
FIG. 7A shows an equilateral triangular support member 50, which has the above-described effect 1).
FIG. 7B shows a support member 51 in which an isosceles triangle whose apex angle is an obtuse angle is inclined with respect to the conveying direction of the thin plate material 14. It can be higher than the member 50.
FIG. 7C shows an isosceles triangular support member 52 having an acute apex angle. As a result, the above-described effect 3) can be obtained, and the rigidity is maintained by increasing the height and the cross-sectional area by the amount corresponding to the decrease in rigidity due to the narrow width (described above 2). ) Effect).

図７（Ｄ）は、長方形の１つの角部を面取りした（切欠いた）支持部材５３であり、図７（Ｅ）は、台形の支持部材５４である。これにより、上記した１）の作用効果が得られる。
更に、図７（Ｆ）は、台形の支持部材５５を、図７（Ｇ）は、平行四辺形の支持部材５６を、それぞれ薄板材１４の搬送方向に対して傾けているため、上記した１）の作用効果を更に高めることができる。 FIG. 7D shows a support member 53 in which one corner of a rectangle is chamfered (notched), and FIG. 7E shows a trapezoidal support member 54. Thereby, the effect 1) described above can be obtained.
Further, FIG. 7 (F) shows the trapezoidal support member 55 and FIG. 7 (G) shows the parallelogram support member 56 inclined with respect to the conveying direction of the thin plate material 14, respectively. ) Can be further enhanced.

図７（Ｋ）は、円を１／４に分断した形状の支持部材６０であるため、上記した３）、４）の作用効果がある。 Since FIG. 7H shows the support member 57 having a circular shape (the contour is a curved surface), the effect 1) described above is obtained.
Since FIG. 7 (I) shows the semicircular support member 58, the above-described operational effect 4) can be obtained.
In FIG. 7 (J), since the elliptical support member 59 is inclined obliquely with respect to the conveying direction of the thin plate member 14, the effect of the above 1) can be further enhanced.
Since FIG. 7K shows the support member 60 having a shape obtained by dividing a circle into quarters, the above-described effects 3) and 4) are obtained.

なお、支持部材は、角部を切欠いたり円弧にした方が薄板材を滑らかに搬送でき、また、細い方が昇降手段をコンパクトかつ安価にできるが、剛性が不足するのであれば、幅や高さを増す、等の設計コンセプトにより、どのような支持部材を用いるかを決定することが好ましい。
このため、支持部材は、その全長（薄板材の幅方向全体）にわたって、同一形状にする必要はない。例えば、支持部材の側断面形状を、端部を四角形にし、薄板材に接触する部分（例えば、長さ方向中央部）だけを円形にすることもできる。
また、支持部材の高さを、薄板材の幅方向中央部に向けて高くすることも可能である。 Note that the support member can be used to smoothly transport a thin plate if the corners are notched or arcuated, and the thin one can make the lifting and lowering means more compact and inexpensive. It is preferable to determine which support member is used according to a design concept such as increasing the thickness.
For this reason, it is not necessary for the support member to have the same shape throughout its entire length (the entire width direction of the thin plate material). For example, the side cross-sectional shape of the support member may be a square end, and only the portion that contacts the thin plate material (for example, the central portion in the length direction) may be circular.
In addition, the height of the support member can be increased toward the center in the width direction of the thin plate material.

更に、図８に示す本発明の第４の実施の形態に係る薄板材の打抜き装置７０のように、下型７１（下型１１と略同様の構成）に、リフト機構７２を設けることもできる。
このリフト機構７２は、対となる昇降手段７３、７４と、これに設けられた支持ロッド（支持部材の一例）７５を有している。なお、昇降手段７３、７４は油圧シリンダーや弾性部材（バネ材）で構成され、支持ロッド７５は支持ロッド２４と同様の構成である。
対となる昇降手段７３、７４は、鉛直方向に配置され、その下部が、下型７１の両側側部（下型７１と上型７６を有する金型７７の外部）に取付け固定されている。
このように、各昇降手段７３、７４は、薄板材１４の両側方の位置（平面視して薄板材１４と重ならない位置）に設けられている。 Furthermore, a lift mechanism 72 can be provided in the lower mold 71 (substantially the same configuration as the lower mold 11) as in the thin plate punching apparatus 70 according to the fourth embodiment of the present invention shown in FIG. .
The lift mechanism 72 includes lifting means 73 and 74 that form a pair, and a support rod (an example of a support member) 75 provided on the lift means 73 and 74. The elevating means 73 and 74 are constituted by a hydraulic cylinder or an elastic member (spring material), and the support rod 75 has the same configuration as the support rod 24.
The pair of lifting means 73 and 74 are arranged in the vertical direction, and lower portions thereof are fixedly attached to both side portions of the lower mold 71 (outside of the mold 77 having the lower mold 71 and the upper mold 76).
In this way, the elevating means 73 and 74 are provided at positions on both sides of the thin plate material 14 (positions that do not overlap the thin plate material 14 in plan view).

また、図９に示す本発明の第５の実施の形態に係る薄板材の打抜き装置８０のように、下型８１（下型１１と略同様の構成）に、リフト機構８２を設けることもできる。
このリフト機構８２は、対となる昇降手段８３、８４と、これに設けられた支持ロッド（支持部材の一例）８５を有している。なお、昇降手段８３、８４は、油圧シリンダーや弾性部材（バネ材）で構成され、支持ロッド８５は支持ロッド２４と略同様の構成である。
対となる昇降手段８３、８４は、鉛直方向に配置され、下型８１の内部（下型８１と上型８６を有する金型８７の内部）であって、薄板材１４の両側方の位置（平面視して薄板材１４と重ならない位置）に取付け固定されている。 Further, a lift mechanism 82 can be provided on the lower die 81 (substantially the same configuration as the lower die 11) as in a thin plate punching device 80 according to the fifth embodiment of the present invention shown in FIG. .
The lift mechanism 82 includes a pair of lifting means 83 and 84 and a support rod (an example of a support member) 85 provided on the lift means 83 and 84. The elevating means 83 and 84 are constituted by a hydraulic cylinder or an elastic member (spring material), and the support rod 85 has substantially the same configuration as the support rod 24.
The pair of elevating means 83 and 84 are arranged in the vertical direction, and are located inside the lower mold 81 (inside the mold 87 having the lower mold 81 and the upper mold 86) and on both sides of the thin plate material 14 ( It is attached and fixed at a position that does not overlap the thin plate material 14 in plan view.

続いて、本発明の一実施の形態に係る薄板材の打抜き方法について、図１〜図３を参照しながら説明する。
まず、薄板材１４を金型１３内まで搬送する。
このとき、図１（Ａ）〜（Ｃ）に示すように、上型１２が待機位置にあるため、支持ロッド２４も昇降ロッド２２、２３によって上昇した位置を維持し、薄板材１４は持上げられた状態を維持する。 Then, the punching method of the thin plate material which concerns on one embodiment of this invention is demonstrated, referring FIGS. 1-3.
First, the thin plate material 14 is transported into the mold 13.
At this time, as shown in FIGS. 1A to 1C, since the upper mold 12 is in the standby position, the support rod 24 also maintains the position raised by the elevating rods 22, 23, and the thin plate material 14 is lifted. Maintain the state.

次に、薄板材１４の搬送を停止した状態で、金型１３により薄板材１４の打抜きを行う。
このとき、図２（Ａ）〜（Ｃ）に示すように、上型１２の下降に伴い、支持ロッド２４が昇降ロッド２２、２３によって凹部２６内まで下降して、薄板材１４が下型１１上に配置される。
なお、リフト機構の昇降手段にバネ材を用いた場合は、下型１１に対する上型１２の押圧により、バネ材が圧縮されて、支持ロッド２４が凹部２６内に収容される。 Next, the thin plate material 14 is punched by the mold 13 while the conveyance of the thin plate material 14 is stopped.
At this time, as shown in FIGS. 2A to 2C, as the upper mold 12 is lowered, the support rod 24 is lowered into the recess 26 by the lifting rods 22 and 23, and the thin plate material 14 is moved to the lower mold 11. Placed on top.
When a spring material is used for the lifting means of the lift mechanism, the spring material is compressed by pressing the upper mold 12 against the lower mold 11 and the support rod 24 is accommodated in the recess 26.

薄板材１４の打抜き終了後、図１（Ａ）〜（Ｃ）に示すように、上型１２を元の待機位置まで上昇させる。
このとき、支持ロッド２４も昇降ロッド２２、２３によって凹部２６内から上昇し、薄板材１４が持上げられる。
これにより、打抜きによって剛性が低下した材料の撓みやバタツキを抑制、更には防止した状態で、薄板材１４を搬送できる。 After the punching of the thin plate material 14 is finished, the upper mold 12 is raised to the original standby position as shown in FIGS.
At this time, the support rod 24 is also raised from the inside of the recess 26 by the elevating rods 22 and 23, and the thin plate material 14 is lifted.
Thereby, the thin plate material 14 can be conveyed in a state in which the bending and fluttering of the material whose rigidity has been reduced by punching is suppressed and further prevented.

なお、図８に示す薄板材の打抜き装置７０や図９に示す薄板材の打抜き装置８０でも、上記の方法と同様の方法で、薄板材１４の打抜きを行う。
ここで、リフト機構の昇降手段にバネ材を用いた場合、上型７６、８６を下型７１、８１に対して押圧することで、常時は薄板材１４を支持する支持ロッド７５、８５を、下方へ押し下げることができる。 The thin plate material punching device 70 shown in FIG. 8 and the thin plate material punching device 80 shown in FIG. 9 also punch the thin plate material 14 in the same manner as described above.
Here, when a spring material is used for the lifting means of the lift mechanism, by pressing the upper dies 76 and 86 against the lower dies 71 and 81, the support rods 75 and 85 that normally support the thin plate material 14 are It can be pushed down.

以上のように、本発明の薄板材の打抜き装置及びその打抜き方法を適用することで、材料の撓みやバタツキを抑制、更には防止できるため、材料の送り速度を遅くして、鉄心片の打抜き加工を行う必要がなくなる。
従って、生産性を低下させることなく、安定した打抜き加工を実施できる。 As described above, by applying the punching device and method for punching a thin plate of the present invention, it is possible to suppress and further prevent bending and fluttering of the material. No need to process.
Accordingly, stable punching can be performed without reducing productivity.

以上、本発明を、実施の形態を参照して説明してきたが、本発明は何ら上記した実施の形態に記載の構成に限定されるものではなく、特許請求の範囲に記載されている事項の範囲内で考えられるその他の実施の形態や変形例も含むものである。例えば、前記したそれぞれの実施の形態や変形例の一部又は全部を組合せて本発明の薄板材の打抜き装置及びその打抜き方法を構成する場合も本発明の権利範囲に含まれる。
例えば、前記実施の形態においては、本発明の薄板材の打抜き装置及びその打抜き方法を用いて、積層鉄心を構成する鉄心片を打抜く場合について説明したが、本発明はこれに限定されることなく、薄板材に対し予め設定した打抜き加工を行う場合であれば、適用可能である。この場合、打抜き加工を行う薄板材は、１枚でもよく、また、２枚以上の複数枚積層したものでもよい。そして、薄板材の厚みや幅等は、適用用途に応じて種々変更できる。 As described above, the present invention has been described with reference to the embodiment. However, the present invention is not limited to the configuration described in the above embodiment, and the matters described in the scope of claims. Other embodiments and modifications conceivable within the scope are also included. For example, a case where the thin plate material punching apparatus and the punching method of the present invention are configured by combining a part or all of the above-described embodiments and modifications is also included in the scope of the present invention.
For example, in the above-described embodiment, the case where the core piece constituting the laminated core is punched using the thin plate punching apparatus and punching method of the present invention has been described, but the present invention is limited to this. However, the present invention is applicable to a case where a preset punching process is performed on a thin plate material. In this case, the number of thin plate materials to be punched may be one, or a laminate of two or more sheets. And the thickness, width, etc. of the thin plate material can be variously changed according to the application.

また、本発明の薄板材の打抜き装置（打抜き方法）のリフト機構は、従来の打抜き装置の金型に設けられたリフターの代わりに使用できるが、このリフターと併用して使用することもできる。
なお、リフト機構の設置場所は、特に限定されるものではなく、例えば、刃物（パンチやダイ）に干渉しない場所であればよく、また、リフト機構の規模や設置範囲も、必要に応じて適宜調整できる。特に、鉄心片の打抜きの最終工程であるブランク抜きの前後にリフト機構を設けた場合、本発明の効果がより顕著になる。これは、この工程での薄板材の剛性が、他の工程に比べて低いことによる。 Further, the lift mechanism of the thin plate material punching device (punching method) of the present invention can be used in place of the lifter provided in the mold of the conventional punching device, but can also be used in combination with this lifter.
The installation location of the lift mechanism is not particularly limited, and may be any location that does not interfere with the cutting tool (punch or die), and the scale and installation range of the lift mechanism may be appropriately determined as necessary. Can be adjusted. In particular, when a lift mechanism is provided before and after blank blanking, which is the final step of punching iron core pieces, the effect of the present invention becomes more remarkable. This is because the rigidity of the thin plate material in this process is lower than in other processes.
