図１１を参照してインサート保持状態について説明する。
打ち抜き形成された第１の打抜片ａｈは図で底部側（第２の材料当たり側）は上部側（パンチ当たり側）より狭い形態となる。また、第２の抜き穴ｂｋも図で底部側は上部側より狭い形態となる。
また、第１の打抜片ａｈは打抜時に圧力により収縮した状態で打抜かれるので解放後は、可動側パンチ穴１３および固定側パンチ穴１６よりもわずかに幅広形態となる。
パンチ１０に押されて第２の材料Ｂに第２の抜き穴ｂｋを形成し該第２の抜き穴ｂｋにインサートされた第１の打抜片ａｈの下部側の一部分は、パンチ１０の打抜速度や第２の材料Ｂの収縮などの作用によって、第２の抜き穴ｂｋ下部から下方に一部分が突出した状態（第２の材料Ｂの底部面から一部分が突き出した状態）となり、その突き出した一部分は固定側パンチ穴１６に入り込んだ一部分入り込み状態となる（図１１下図参照）。
この一部分入り込み状態のまま第２の材料Ｂを移動させようとすると、正常な送り量ができない事態が生じたり、第１の打抜片ａｈや第２の抜き穴ｂｋが損傷してしまう等の不具合が生じる。
かかる不具合を、材料離し部１７からエアーＥによる材料離し操作によって、第２の材料Ｂの固定型１８からの離しおよび固定側パンチ穴１６からの第１の打抜片ａｈの入っている一部分をお完全に出された抜け解放状態とする。
The insert holding state will be described with reference to FIG.
The first punched piece ah formed by punching has a shape in which the bottom side (second material hitting side) is narrower than the upper side (punching hitting side). Further, the second punch hole bk is also narrower on the bottom side than on the top side in the drawing.
Further, since the first punched piece ah is punched in a contracted state due to pressure during punching, the first punched piece ah is slightly wider than the movable punch hole 13 and the fixed punch hole 16 after release.
A second punched hole bk is formed in the second material B by being pushed by the punch 10, and a part on the lower side of the first punched piece ah inserted into the second punched hole bk Due to the action such as the drawing speed and the contraction of the second material B, a part protrudes downward from the lower part of the second hole bk (a part protrudes from the bottom surface of the second material B), and the protrusion A part of the part enters the fixed side punch hole 16 (see the lower part of FIG. 11).
If it is attempted to move the second material B in this partially entering state, a situation in which a normal feeding amount cannot be performed occurs, or the first punched piece ah and the second punched hole bk are damaged. A malfunction occurs.
Such a defect is caused by removing the second material B from the fixed mold 18 and part of the first punched piece ah from the fixed side punch hole 16 by the material separating operation by the air E from the material separating portion 17. It is assumed that it has been completely released.
固定型１８から離され搬送（移動）された第２の材料Ｂのインサート保持状態にある第１の打抜片ａｈは、第２の抜き穴ｂｋからその一部分が下方に突き出している状態にある（図１１上図）。
次の打抜時に、かかるインサート保持状態にある第１の打抜片ａｈは型内に位置していて、該次の打抜動作による固定型１８と第２の可動型１４とのプレス動作（挟持抑え動作）によってインサート保持状態が矯正されるようになっている。
The first punched piece ah in the insert holding state of the second material B separated from the fixed mold 18 and conveyed (moved) is in a state in which a part thereof protrudes downward from the second punch hole bk. (Upper figure of FIG. 11).
At the time of the next punching, the first punched piece ah in the insert holding state is located in the mold, and the pressing operation of the fixed mold 18 and the second movable mold 14 by the next punching operation ( The insert holding state is corrected by the clamping operation).
第１の材料Ａの一部を打抜いて形成した第１の打抜片ａｈで第２の材料Ｂの一部を打ち抜く第２の打抜穴ｂｋの形成時に第１の打抜片ａｈが該第２の打抜穴ｂｋ内に押し込まれ保持されたインサート保持状態を形成するものであるので、第１の打抜片ａｈと第２の打抜穴ｂｋとのズレが全く生じない綺麗な嵌め込みインサート保持状態を実現する。
また、同時に多数のパンチ（ここでは８本）により同時に多数の第１の打抜片ａｈ（ここでは８個）を同時にインサート保持状態（インサート保持形態）とすることを実現するので、不良があ生じない生産効率の高い方法および装置を実現する。
When the second punched hole bk for punching a part of the second material B is formed by the first punched piece ah formed by punching a part of the first material A, the first punched piece ah is formed. Since the insert holding state pushed and held in the second punching hole bk is formed, the first punching piece ah and the second punching hole bk are not displaced at all. Realizes the inserted insert holding state.
In addition, since a large number of first punched pieces ah (here, 8 pieces) are simultaneously placed in the insert holding state (insert holding form) by a large number of punches (here, 8 pieces) at the same time, there is a defect. To achieve a method and apparatus with high production efficiency that does not occur.
第１の材料Ａおよび第２の材料Ｂがプラスチック製部材（ポリエチレンテレフタレート、高密度／低密度ポリエチレン、塩化ビニール、ポリプロピレン、ポリスチレン、ＡＳ樹脂、ＡＢＳ樹脂、ポリアミド、ポリカーボネート、ポリ乳酸等々）、紙製部材、植物製部材、ゴム製部材、硬度６０ＨＶ(ビッカース硬さ：HV換算)以下の金属（金、銀、プラチナ等の貴金属、鉛、銅など、例えばアルミニウム系では純アルミ、Al-Mn、Al-Mgなど、）、硬度６０ＨＶ以下の無機物又はこれらの組合せ部材とするのがよい。硬度１２０ＨＶ以下、硬度１０００ＨＶ以下又は硬度８０ＨＶ以下の金属や無機物とするのもよい。
また、第１の材料Ａと第２の材料Ｂは性質や材質等の異なるものとするのもよい。
例えば、第２の材料Ｂを絶縁性のものとし、第１の材料Ａを導電性のものとする、又はその逆にする。
例えば、第２の材料Ｂを透明部材とし、第１の材料Ａを非透明部材ないしカラー透明部材のものとする、又はその逆にする。
また、第１の材料Ａおよび第２の材料Ｂはパンチ等が打抜可能な硬さのものであれば、硬度６０ＨＶ以上の金属、無機物であってもよい。例えば、ステンレス鋼（２００ＨＶ以上）であるＳＵＳ２０１では硬度２５３ＨＶである。
The first material A and the second material B are plastic members (polyethylene terephthalate, high density / low density polyethylene, vinyl chloride, polypropylene, polystyrene, AS resin, ABS resin, polyamide, polycarbonate, polylactic acid, etc.), made of paper Parts, plant parts, rubber parts, metals of hardness 60HV (Vickers hardness: HV conversion) or less (gold, silver, platinum and other precious metals, lead, copper, etc. For example, pure aluminum, Al-Mn, Al in the aluminum series -Mg or the like), an inorganic material having a hardness of 60 HV or less, or a combination member thereof. A metal or an inorganic substance having a hardness of 120 HV or less, a hardness of 1000 HV or less, or a hardness of 80 HV or less may be used.
Further, the first material A and the second material B may be different in properties and materials.
For example, the second material B is insulative and the first material A is conductive, or vice versa.
For example, the second material B is a transparent member, and the first material A is a non-transparent member or a color transparent member, or vice versa.
Further, the first material A and the second material B may be a metal or inorganic material having a hardness of 60 HV or more as long as the material can be punched by a punch or the like. For example, in SUS201 which is stainless steel (200HV or more), the hardness is 253HV.
第１の材料Ａと第２の材料Ｂはその厚みが異なるものとするのもよい。
この場合でも打抜動作は、固定側パンチ穴１６にはパンチ１０の下部エッジは届かない位置（下死点）で停止する打抜動作である。それには、パンチ１０の下部エッジが可動側パンチ穴１３の下開口より内側に位置する形態も含まれる。
The first material A and the second material B may have different thicknesses.
Even in this case, the punching operation is a punching operation that stops at a position where the lower edge of the punch 10 does not reach the fixed side punch hole 16 (bottom dead center). This includes a form in which the lower edge of the punch 10 is positioned inside the lower opening of the movable punch hole 13.

また、材料離し部を固定型１８側に設けた該固定型１８上面から突出して第２の材料を押上離す動作の棒部材からなる材料離し部３３を複数個所設けた構成としている。
図１２の下図に示すように、第１の可動型１１の上昇すなわちパンチ１０の上昇の上昇時に、パンチ１０が第１の打抜穴ａｋに貫通した形態であるので、第１の材料Ａがパンチ１０に保持された状態となってしまう危険がある。分離ピン２７が第１の材料Ａに当たり、その自重によりパンチ１０により引き上げられる第１の材料Ａの上昇を抑え、パンチ１０のみが上昇するようにして該パンチ１０が第１の打抜穴ａｋから抜外れるようにしている。
分離ピン２７の長さは、第１の可動型１１が上死点に位置する状態で、パンチ１０の下部先端より０．５ｍｍ〜５ｍｍ程度下方にピン下部先端が位置する長さである。
In the second embodiment of the present invention shown in FIG. 12, the main difference from the first embodiment is that the first material A can be moved up and down to completely separate from the punch 10 when the first movable mold 11 is raised. This is in that a plurality of separation pins 27 having a free form are provided.
Further, a plurality of material separating portions 33 each including a rod member that protrudes from the upper surface of the fixed mold 18 provided on the fixed mold 18 side to push up and separate the second material are provided.

There is a danger of being held by the punch 10. The separation pin 27 hits the first material A, and suppresses the rise of the first material A pulled up by the punch 10 by its own weight, so that only the punch 10 is lifted, and the punch 10 is removed from the first punching hole ak. I try to remove it.
The length of the separation pin 27 is a length at which the tip of the lower portion of the pin is located about 0.5 mm to 5 mm below the lower tip of the punch 10 in a state where the first movable die 11 is located at the top dead center.

A repulsive biasing member 32 (such as a compression coil spring or a high repulsion rubber member) is provided between them.
Further, the material separation portion 34 is formed as a material separation portion 34 including a suction hole provided on the second movable mold 14 side for performing a suction separation operation.
打抜時は、第１の可動型１１が下降すると反発付勢部材３２に押さえ型３０が押され反発付勢部材２１が収縮して押さえ型３０が下降し、押さえ型３０と第２の可動型１４とで第１の材料Ａを挟み押さえ付ける、該押さえ付け状態で第１の材料Ａをパンチ１０で打抜く。
以後の工程動作は実施例１と略同様である。
At the time of punching, when the first movable mold 11 is lowered, the presser mold 30 is pressed by the repulsive biasing member 32 and the repulsive biasing member 21 is contracted, so that the presser mold 30 is lowered, and the presser mold 30 and the second movable mold 11 are moved. The first material A is sandwiched and pressed between the mold 14 and the first material A is punched with the punch 10 in the pressed state.
Subsequent process operations are substantially the same as those in the first embodiment.
図１５、１６に示す本発明の実施例４において、前記実施例３と主に異なる点は、第１の材料通し隙間１２を、第１の材料Ａと同じ厚さの例えば異なる色彩の第１の材料Ａ１と第１の材料Ａ２を重ねて通す隙間距離とし、第２の材料通し隙間１５を、第２の材料Ｂの２倍の厚さの第２の材料Ｂ２を通す隙間距離とし、パンチ１０で第１の材料Ａ１、Ａ２を打抜いて第１の打抜片ａｈ１と第１の打抜片ａｈ２が重なった第１の重ね打抜片ａｈｋを形成し、該第１の重ね打抜片ａｈｋの打抜動作と固定側パンチ穴１６のエッジによって第２の材料Ｂ２を打抜いて第２の打抜穴ｂｋ２を形成するとともに、第１の重ね打抜片ａｈｋが該第２の打抜穴ｂｋ２に押し込まれ（打込まれ）たインサート形態となる点である。
