Description

本発明は、屑巻上げ防止機構を備えたストリッピング型に係り、特に、段ボール紙、厚紙などの紙製素材からなるシートに箱体などの展開形状に打ち抜き処理された後に、シートの製品部から不要な打抜き屑を打ち抜き分離するための雄型と雌型とを備えて構成されているストリッピング型に関する。   The present invention relates to a stripping mold having a scrap hoisting prevention mechanism, and in particular, from a product portion of a sheet after being punched into a developed shape such as a box body on a sheet made of a paper material such as corrugated paper or cardboard. The present invention relates to a stripping die configured to include a male die and a female die for punching and separating unnecessary punching waste.

例えば、包装用箱体は、段ボール紙、厚紙などの紙製素材からなるシート(ブランクシート)から包装すべき内容物のよって様々な製品形状に自動製函機によって打ち抜かれて形成される。また、同じく、包装用箱体内を内容物の応じて様々に仕切るように内設される仕切り体も自動製函機によって打ち抜かれて形成される。
自動製函機では、まず、製函ラインにシートが給紙され、製函ラインに装備されている雄型と雌型とを有する平盤打抜き型装置によってシートに展開された製品形状(箱体の展開形状)が裁断される打ち抜き処理(切り込み処理)が行われる。このとき、製品形状に裁断された製品部と製品部以外の打抜き屑とは繋ぎ部を介してシートに繋ぎ止められている。
つぎに、製函ラインにおける平盤打抜き型装置のデリバリー部に装備されている雄型と雌型とを有するストリッピング型によってシートの製品部から不要な打抜き屑を打ち抜いて分離して除去する打抜き屑の分離処理(ストリッピング処理)が行われることで、展開された包装用箱体などが製作されるようになっている。
For example, a packaging box is formed by punching an automatic box making machine into various product shapes according to contents to be packaged from a sheet (blank sheet) made of a paper material such as corrugated cardboard or cardboard. Similarly, a partition body provided so as to partition the packaging box in various ways according to the contents is also formed by being punched out by an automatic box making machine.
In an automatic box making machine, first, a sheet is fed to a box making line, and a product shape (box body) developed on a sheet by a flat plate punching die device having a male mold and a female mold equipped in the box making line. A punching process (cutting process) is performed in which the developed shape is cut. At this time, the product part cut into the product shape and punching waste other than the product part are secured to the sheet via the joint part.
Next, punching is performed by punching and removing unnecessary punching waste from the product portion of the sheet by a stripping die having a male die and a female die provided in a delivery part of a flat plate punching die device in a box making line. By performing the separation process (stripping process) of waste, an unfolded packaging box or the like is manufactured.

近年では、自動製函機による包装用箱体などの展開された製品部を、シートから打ち抜き加工することが高速化されてきており、このよう状況に対応させたストリッピング型の開発が求められてきている。特に、平盤打抜き型装置によって打ち抜き処理された後に、繋ぎ部を介して製品部に繋ぎ止められている不要な打抜き屑を製品部から分離して除去するためのストリッピング型の高速化対応が求められてきている。   In recent years, it has become faster to punch out unfolded product parts such as packaging boxes by automatic box making machines from sheets, and the development of stripping molds that can cope with this situation is required. It is coming. In particular, after stripping processing with a flat plate punching die device, stripping type high speed support for separating and removing unnecessary punching scraps that are secured to the product part through the joint part from the product part is possible. It has been demanded.

そこで、展開された製品形状に打ち抜き処理されたシートの製品部から不要な打抜き屑を分離して除去するためのストリッピング型としては、例えば、特許文献1から特許文献3などにおいて知られている。   Therefore, as a stripping mold for separating and removing unnecessary punching waste from the product portion of the sheet punched into the developed product shape, for example, Patent Document 1 to Patent Document 3 are known. .

特開平10−594号JP-A-10-594 特開2000−308995号JP 2000-308995 A 特開2007−175805号JP2007-175805

しかしながら、特許文献1〜特許文献3において開示されている従来技術では、雌型の表側に搬入支持されたシートの製品部から打ち抜かれて雌型の裏側に向けて分離された不要な打抜き屑が、雌型の表側に巻き上げられることを防ぐ打抜き屑の屑巻上げ防止機構などを備えていない。
そのために、従来技術では、雄型の降下移動によって、雄型に備えられている屑押出し部材により製品部から打抜き屑を雌型の裏側に打ち抜き分離させた後に、雄型が上昇移動して雌型の上方に戻るときに、製品部から分離された打抜き屑が雌型の上や製品部の上に巻き上げられる(舞い上げられる)ことがある。
特に、打抜き屑を打ち抜き分離する分離ショット速度が高速で行われた場合などには、雄型が雌型から離れるときの雄型の上昇移動時に発生する風圧などによって分離された打抜き屑が雌型の上や製品部の上に巻き上げられることが起き易いものとなっていた。
However, in the prior art disclosed in Patent Documents 1 to 3, unnecessary punching wastes punched from the product portion of the sheet carried in and supported on the front side of the female mold and separated toward the back side of the female mold are removed. In addition, it does not include a scrap hoisting prevention mechanism for punching scraps that prevents the female mold from being wound up on the front side.
Therefore, in the prior art, the male mold is moved up and down after the male mold is moved downward by punching and separating the punched waste from the product part to the back side of the female mold by the scrap pushing member provided in the male mold. When returning to the upper part of the mold, the punching waste separated from the product part may be rolled up (swelled up) on the female mold or on the product part.
In particular, when the separation shot speed for punching and separating the punching waste is performed at a high speed, the punching waste separated by the wind pressure generated when the male die moves upward when the male die leaves the female die is the female die. It was easy to happen to be rolled up on the product or the product part.

打ち抜き分離された打抜き屑が、雌型の上に跳ね上った場合などには、つぎに雌型の上に搬入されたシートの製品部から打抜き屑を打ち抜き分離する分離ショット作業の妨げになるなどのおそれがあった。
また、製品部の上に打抜き屑が巻き上げられた場合には、製品部が数十枚単位で重ねられて商品の包装メーカに搬出されるときに、重ねられた製品部の間に打抜き屑が混入し、メーカの信頼性を低下させることになっていた。
When the punched and separated punch scraps up on the female mold, the separation shot operation for punching and separating the punch scraps from the product portion of the sheet carried on the female mold is hindered. There was a fear.
In addition, when punched waste is rolled up on the product part, when the product part is stacked in units of several tens of sheets and transported to a product packaging manufacturer, the punched waste is generated between the stacked product parts. It was supposed to deteriorate the reliability of the manufacturer.

そこで、本発明は、前記課題を解消するために創案されたものであり、製品部から打ち抜き分離された打抜き屑が、製品部の上や雌型の上に巻き上げられることを防ぐ打抜き屑の巻上げ防止機構を備えたストリッピング型を提供することにある。   Accordingly, the present invention has been developed to solve the above-mentioned problems, and is a punching scrap that prevents punching scraps punched and separated from the product part from being rolled up on the product part or the female mold. An object of the present invention is to provide a stripping mold having a prevention mechanism.

In order to solve the above-mentioned problem, in the present invention, a stripping mold comprising a male mold and a female mold for separating punched waste from a product portion of a sheet punched into a developed shape,
The male mold includes a scrap extruding member disposed along the developed shape of the product portion, and when the punching scrap is punched and separated from the product portion by the scrap extruding member, the punching scrap The female mold is formed in a shape substantially similar to the developed shape of the product part, and the whole product part can be supported on the side facing the male mold, and When the punched waste is punched and separated from the product portion to the opposite side of the female mold by the scrap pushing member, a scrap receiving portion for receiving and locking the punched scrap on the opposite side is provided. The scrap receiving portion includes a scrap dividing portion for dividing the punched scrap into a short length at the top portion with the facing side of the male mold as a top portion, and the scrap separating portion from the female portion to the female portion. The opposite side of the mold Characterized in that it is formed in a substantially flared shape towards.

ここで、前記屑押出し部材は、前記製品部の前記展開形状に沿いその展開縁部方向に所定の間隔をおいて並列状に配設されて、当該展開縁部に沿って一連に連なった状態で前記製品部に繋ぎ部を介して繋ぎ止められている前記打抜き屑を、前記屑受止め部との協同で短尺に分断し、短尺に分断された前記打抜き屑を前記屑押え部材との協同で前記雌型の前記反対側に打ち抜き分離するようになし、前記屑受止め部は、前記屑押出し部材の間に対応して前記雌型の外周縁部に備えられて、短尺に分断された前記打抜き屑を前記雌型の前記反対側に受け止め係止するように形成されていることが好適なものとなる。   Here, the scrap extruding members are arranged in parallel with a predetermined interval in the direction of the development edge along the development shape of the product part, and are connected in series along the development edge. The punched scraps secured to the product part via the joint part are divided into short pieces in cooperation with the waste receiving part, and the punched waste pieces cut into short pieces are cooperated with the waste pressing member. The scrap receiving part is provided on the outer peripheral edge of the female mold corresponding to the space between the scrap pushing members, and is cut into short pieces. It is preferable that the punching waste is formed so as to be received and locked on the opposite side of the female die.

また、前記屑押え部材は、前記打抜き屑を串刺し保持する串刺し刃を備えて、前記打抜き屑が前記製品部から打ち抜き分離されるときに、前記屑受止め部に近い位置にて前記打抜き屑を串刺し保持するように、前記雄型に配設されていることが好適なものとなる。   The scrap holding member includes a skewer blade that holds the punched scraps in a skewered manner, and when the punched scraps are punched and separated from the product part, the punching scraps are removed at a position close to the scrap receiving part. It is preferable that the male mold is disposed so as to hold the skewer.

また、前記雌型の外周縁に沿って、該外周縁との間に少なくとも前記打抜き屑の打抜き幅に相当する空間を確保するように外枠部材を備えていることが好適なものとなる。
前記雌型の対面側とは、主に雌型の表側を意味し、反対側とは、主に雌型の裏側を意味する。
In addition, it is preferable that an outer frame member is provided along the outer peripheral edge of the female die so as to ensure at least a space corresponding to the punching width of the punching waste between the outer periphery and the outer peripheral edge.
The facing side of the female mold mainly means the front side of the female mold, and the opposite side mainly means the back side of the female mold.

このような構成によれば、雄型の屑押出し部材により、製品部から雌型の裏側に打ち抜き分離された打抜き屑は、雌型に備えられている屑受止め部によって受止め係止される。これにより、雄型が雌型から離れる雄型の移動のときに、打ち抜き分離された打抜き屑が製品部の上や雌型の上に巻き上げられる(舞い上げられる)ことを防ぐことができる。このとき、打抜き屑は、屑押出し部材の並列方向の幅に相当する長さの短尺に屑受止め部の分断部によって分断されて雌型の裏側に打ち抜き分離され、分断縁部が屑受止め部に受け止め係止される。
また、雄型の屑押出し部材によって雌型の裏側に打ち抜き分離された打抜き屑の跳ね上りを、雌型の外周縁に沿って備えられている外枠部材によって防ぐことができる。つまり、分離された打抜き屑の跳ね上がりを、分離屑受け止めと外枠部材との協同でより確実に防ぐことができる。
According to such a configuration, the punched scraps punched and separated from the product part to the back side of the female mold by the male scrap pushing member are received and locked by the scrap receiving part provided in the female mold. . Thereby, when the male mold moves away from the female mold, it is possible to prevent the punched and separated punched waste from being rolled up on the product part or the female mold. At this time, the punched waste is divided by a split portion of the scrap receiving portion into a short length corresponding to the width in the parallel direction of the scrap extruding member, and is punched and separated on the back side of the female mold, and the split edge portion receives the scrap. It is received and locked to the part.
Further, the jumping up of the punched scraps punched and separated on the back side of the female mold by the male scrap extruding member can be prevented by the outer frame member provided along the outer peripheral edge of the female mold. That is, the jumping of the separated punching waste can be more reliably prevented by the cooperation of the separation waste catcher and the outer frame member.

また、本発明では、前記屑押え部材が、先端に串刺し刃を有する支持部と、この支持部の外側に摺動可能に被嵌されて、前記雄型が前記雌型から離間するときに、前記シートに対する前記支持部の串刺し状態を解除するための串刺し解除部と、この串刺し解除部を前記支持部の前記串刺し刃方向に付勢する弾発材とを備えて構成されていることを特徴とする。   Further, in the present invention, when the scrap pressing member is slidably fitted on the outer side of the support portion having a skewer blade at the tip, and the male mold is separated from the female mold, A skewer release portion for releasing the skewered state of the support portion with respect to the sheet, and a resilient material that urges the skewer release portion in the skewer blade direction of the support portion. And

このような構成によれば、前記のように、製品部から打抜き屑が打ち抜き分離されるときに、雌型の上にシートを串刺し保持する屑押え部材は、串差し刃を有する支持部に、シート(打抜き屑)に対する串刺し状態を解除させるための串刺し解除部を串刺しバネ材により串刺し刃方向に付勢させて備えている構成としていることで、打抜き屑を雌型の裏側に打ち抜き分離させた後に、雄型が雌型から離間する雄型の移動のときに、シート(打抜き屑)に対する串刺し状態を確実に解除させることができる。   According to such a configuration, as described above, when punching waste is punched and separated from the product portion, the scrap holding member that holds the sheet on the female die is held on the support portion having the skewer blade. By having a structure that includes a skewer release portion for releasing the skewered state of the sheet (punched waste) by biasing the skewer blade direction by the skewer spring material, the punched waste is punched and separated on the back side of the female mold. Later, when the male mold moves away from the female mold, the skewered state of the sheet (punching waste) can be reliably released.

本発明の屑巻上げ防止機構を備えたストリッピング型は、以上のように構成されていることで、雄型の屑押出し部材によって雌型の裏側に打ち抜き分離された打抜き屑を、雌型側に備えられている屑受け止め部によって受け止め係止することができることで、雄型が雌型から勢いよく離れる動きによって打抜き屑が製品部の上や雌型の上(表側)に巻き上げられる(舞い上げられる)ことを確実に防ぐことができる。
これにより、打抜き屑を製品部から打ち抜き分離する打抜きショット速度の高速化に対応してシートの製品部からの打抜き屑の打ち抜き分離が可能となる。換言すれば、包装用箱体などを効率的に製函することが可能となる。
The stripping die provided with the scrap hoisting prevention mechanism of the present invention is configured as described above, and the punching scraps punched and separated on the back side of the female die by the male die pushing member are moved to the female die side. Since it can be received and locked by the scrap receiving part provided, the punching scraps are wound up (swelled up) on the product part or on the female mold (front side) by the movement of the male mold away from the female mold vigorously. ) Can be surely prevented.
Accordingly, punching waste can be separated from the product portion of the sheet in correspondence with an increase in the punching shot speed for punching and separating the punch waste from the product portion. In other words, it is possible to efficiently form a packaging box or the like.

また、雄型の降下移動によって雌型の上に支持されている製品部から打抜き屑を、雌型の裏側に打ち抜き分離すると同時に、雄型との対面側頂部に備えられている屑受止め部の屑分断部によって打抜き屑を短尺に分断し、短尺に分断した打抜き屑を屑受止め部の幅広下面によって雌型の裏側に受け止め係止させることができる。In addition, punching waste from the product portion supported on the female die by the descent movement of the male die is punched and separated on the back side of the female die, and at the same time, a dust catching portion provided on the top portion facing the male die It is possible to divide the punched waste into short pieces by the waste piece dividing portion, and to receive and lock the punched waste pieces cut into short pieces on the back side of the female die by the wide lower surface of the waste receiving portion.
これにより、雄型が雌型から離れる上昇移動時に発生する風圧などによって、雌型の裏側に打ち抜き分離された打抜き屑が製品部の上や雌型の上に巻き上げられる(舞い上げられる)ことを防ぐことができ、しかも、その打ち抜き分離作業の高速化が、屑分断部による打抜き屑の速やか、かつ、確実な短尺分断によって期待できる。As a result, the punching scraps punched and separated on the back side of the female die are rolled up on the product part or the female die by the wind pressure generated when the male die moves away from the female die. In addition, it is possible to prevent the punching separation work from being speeded up by the quick and reliable short cutting of the punched waste by the waste cutting part.

That is, when punching waste b is punched and separated from the product part B, the sheet S is skewed and held so as not to move from a fixed position (predetermined position) on the female mold A2, and the punching separated from the product part B is performed. It plays the role of pushing out the waste b to the back side of the female mold A2 in cooperation with the waste pushing member 2.

この屑押え部材3は、図3の(b)に示すように、先端に串刺し刃4を有する支持部3aと、この支持部3aの外側に摺動可能に被嵌されて、雄型A1が雌型A2から離れるときに、打抜き屑bに対する支持部3aの串刺し状態を解除するための串刺し解除部3bと、この串刺し解除部3bを支持部3aの串刺し刃4方向に常時付勢するためのバネ材3cとを備えて構成されている。   As shown in FIG. 3 (b), the scrap holding member 3 is slidably fitted on a support portion 3a having a skewer blade 4 at the tip and on the outside of the support portion 3a. When leaving the female mold A2, the skewer release part 3b for releasing the skewered state of the support part 3a with respect to the punching scraps b, and the skewer release part 3b for constantly biasing the skewer release part 3b in the direction of the skewer blade 4 of the support part 3a And a spring material 3c.

支持部3aは、所定の長さを有するピン形状に形成され、下端(先端)に略尖がり形状の串差し刃4を備えているとともに、上端(後端)には止着鍔部5を備えている。
この支持部3aは、型板1に下面突出状に植設される取付け筒体6の開口上端に止着鍔部5を圧入やネジ込みなどの適宜の止着手段によって止着されることで、長さ方向の上半部側が取付け筒体6に遊嵌状に内在され、下半部側が取付け筒体6から下方へと突出された状態で型板1に取り付けられる。
The support portion 3a is formed in a pin shape having a predetermined length, and includes a skewer blade 4 having a substantially pointed shape at the lower end (front end), and a fastening hook portion 5 at the upper end (rear end). I have.
The support portion 3a is secured by an appropriate fastening means such as press fitting or screwing the fastening collar 5 to the upper end of the opening of the mounting cylinder 6 that is planted on the template 1 so as to protrude downward. The upper half side in the longitudinal direction is loosely fitted in the mounting cylinder 6 and the lower half side is attached to the template 1 in a state of protruding downward from the mounting cylinder 6.

串刺し解除部3bは、取付け筒体6内に移動可能な遊嵌状に挿入される外径を有する所定の長さの円筒形状(パイプ形状)に形成され、その上端(後端)に抜止め鍔部7を備えている。
これにより、串刺し解除部3bは、取付け筒体5内に抜動不能で移動可能に組み込まれ、抜止め鍔部7と取付け筒体6内の支持部3aの止着鍔部5との間に弾装されるコイル形状のバネ材3cによって支持部2aの串刺し刃4方向に常時付勢されるようになっている。つまり、図3の(b)に示すように、支持部3aの串刺し刃4を下端(先端)開口部内に没入状に包囲するようになっている。
The skewering release portion 3b is formed in a cylindrical shape (pipe shape) of a predetermined length having an outer diameter that is inserted in a loosely fitting manner so as to be movable in the mounting cylinder 6, and is prevented from being removed from the upper end (rear end) thereof. A collar 7 is provided.
As a result, the skewering release portion 3b is incorporated in the mounting cylinder 5 so as not to be removable and movable, and between the retaining collar portion 7 and the fixing collar portion 5 of the support portion 3a in the mounting cylinder body 6. The coil-shaped spring material 3c to be mounted is always urged in the direction of the skewer blade 4 of the support portion 2a. That is, as shown in FIG. 3B, the skewer blade 4 of the support portion 3a is immersively enclosed in the lower end (tip) opening.

そして、このように形成されている屑押え部材3は、図3の(b)に示すように、雄型A1の型板1の下面からの屑押出し部材2の押圧部2aよりも串刺し解除部3bをわずかに下方に位置させた垂設寸法にて型板1の下面に取付け筒体6を介して植設されてそれぞれの位置に配設される。   And the waste pressing member 3 formed in this way is a skewer release part rather than the press part 2a of the waste pushing member 2 from the lower surface of the template 1 of male A1, as shown in FIG.3 (b). 3b is planted on the lower surface of the template 1 through the mounting cylinder 6 so as to have a vertical dimension in which it is positioned slightly downward, and is disposed at each position.

具体的述べると、図1および図3の(a)に示すように、各屑押出し部材2の側部に位置し、なおかつ、打抜き屑bが製品部Bから打ち抜き分離されるときに、後記の屑受止め部13,23に近い位置にて打抜き屑bを串刺し保持するようにそれぞれ配設される。
これにより、屑押出し部材2の押圧部2aによって打抜き屑bが製品部Bから雌型A2の裏側に打ち抜き分離(押し出し分離)される直前において、串刺し解除部3bから支持部3aの串刺し刃4が外部に飛び出して雌型A2上で、屑受止め部13,23近くのシートSの打抜き屑b部分に突き刺さる串指し状態で打抜き屑bを保持するようになっている。
つまり、雄型A1が、雌型A1の上方待機位置から降下移動することで、継続する雄型A1の降下移動に伴って串刺し解除部3bの下端開口部が打抜き屑bに突き当たったときに、串刺し解除部3bはバネ材3cの弾発力に反して後退(上昇)する。これにより、支持部3aの串差し刃4が串刺し解除部3bから外部に飛び出し、串刺し刃4が打抜き屑bに突き刺さるシートSの串刺し保持がなされるようになっている。
そして、さらに継続する雄型A1の降下移動により打抜き屑bが屑押出し部材2によって製品部Bから雌型A2の裏側へと打ち抜き分離され、打抜き屑bに掛かる屑押出し部材2の押圧が解かれたときに、串刺し解除部3bはバネ材3cの弾発力によって前進(下降)され、支持部3aの串刺し刃4による打抜き屑bの串刺し保持状態を解除するようになっている。
More specifically, as shown in (a) of FIG. 1 and FIG. 3, located on the side of the scrap pusher member 2, yet, when the punching scrap b is punched separated from the product portion B, below The punching scraps b are arranged so as to be skewered and held at positions close to the scrap receiving portions 13 and 23 , respectively.
Thereby, immediately before the punching waste b is punched and separated (extruded and separated) from the product part B to the back side of the female mold A2 by the pressing part 2a of the scrap pushing member 2, the skewering blade 4 of the support part 3a is released from the skewering release part 3b. The punched waste b is held in a skewered state where it protrudes to the outside and pierces the punched waste b portion of the sheet S near the scrap receiving portions 13 and 23 on the female die A2.
That is, when the male mold A1 moves downward from the upper standby position of the female mold A1, when the lower end opening of the skewering release portion 3b hits the punching waste b with the continued downward movement of the male mold A1, The skewering release portion 3b moves backward (rises) against the elastic force of the spring material 3c. Thereby, the skewer blade 4 of the support portion 3a jumps out from the skewering release portion 3b, and the skewer holding of the sheet S in which the skewer blade 4 pierces the punched waste b is performed.
Further, the punching waste b is punched and separated from the product part B to the back side of the female die A2 by the scrap pushing member 2 by the further downward movement of the male die A1, and the pressing of the scrap pushing member 2 applied to the punching waste b is released. At this time, the skewering release portion 3b is advanced (lowered) by the elastic force of the spring material 3c, and the state in which the punching scraps b of the support portion 3a are held by the skewer blade 4 is released.

このように構成されている屑押え部材3を採用することで、雄型A1が雌型A2から離間するときに、屑押出し部材2によって製品部Bから雌型A2の裏側に打ち抜き分離された打抜き屑bに対する串刺し状態は確実に解除される。
これにより、屑受止め部13,23による打抜き屑bの受け止め係止との協同で、雄型A1が雌型A2から勢いよく離間(上昇移動)する動きによって打抜き屑bが製品部Bの上や雌型A2の上(表側)に巻き上げられることをより一層効果的に、確実に防ぐことができる
By adopting the scrap holding member 3 configured in this way, when the male mold A1 is separated from the female mold A2, the stamping member 2 is punched and separated from the product portion B to the back side of the female mold A2. The skewered state with respect to the waste b is reliably released.
As a result, the punching waste b is moved upward on the product part B by the movement of the male mold A1 away from the female mold A2 (upward movement) in cooperation with the catching and catching of the punching scraps b by the scrap receiving parts 13 and 23. It is possible to more effectively and surely prevent winding up on the female mold A2 (front side) .

また、他の実施形態として、図4に示すように、屑押え部材22を1本のピン部材から形成している。
すなわち、屑押え部材22は、1本のピン部材(軸部材)を用いて所定の長さに形成されているとともに、下端に略尖がり形状の串刺し刃25を備えている。
なお、図示例では、串刺し刃25を1本のみ突出させた構造としているが、2乃至4本などの複数本を突出させた構造とすることができる
As another embodiment, as shown in FIG. 4, the dust holding member 22 is formed from a single pin member.
In other words, the scrap holding member 22 is formed to have a predetermined length using a single pin member (shaft member), and includes a substantially pointed skewer blade 25 at the lower end.
In the illustrated example, only one skewer blade 25 is protruded, but a structure in which a plurality of protrusions such as 2 to 4 are protruded can be used .

また、雄型A1は、図1および図3に示すように、型板1の下面要所に、打抜き屑bを製品部Bから打ち抜き分離するときに、シートSの製品部Bを、雌型A2との間で弾性的に支持するためのスポンジ材やゴム材その他の材料から形成されている弾性部材8を備えている。この弾性部材8は、型板1の下面からの屑押出し部材2の垂下寸法に相当する高さを有する略ブロック形状に形成されている。
これにより、雄型A1と打抜き屑bが打ち抜き分離された製品部Bとを確実に分離するようにしている。つまり、雄型A1の雌型A2に対する型合わせによって製品部Bから打抜き屑bを打ち抜き分離させた後に、雄型A1が雌型A2から離れる上昇移動を開始したときに、製品部Bが屑押出し部材2の内側に引っ掛かるなどによって雄型A1とともに上昇することを防ぐようにしている
Further, as shown in FIGS. 1 and 3, the male mold A <b> 1 is configured such that when the punching waste b is punched and separated from the product section B at the bottom surface of the template 1, the product section B of the sheet S is replaced with the female mold.
