Description

本発明は、物性の異なる構成材料からなる積層体を打ち抜く、例えばディスクの内芯部を打ち抜く打抜き型に関するものである。   The present invention relates to a punching die for punching a laminated body made of constituent materials having different physical properties, for example, punching an inner core portion of a disk.

従来、フィルム状や板状の被打抜き積層体を打ち抜く一般的な打抜き型（１０）としては、図３に示すように、ポンチ（１００）とダイス（２００）とから構成され、ポンチの下端外周に、エッジ刃（１０１）を形成し、ダイスのポンチの対応位置に、上端外周にエッジ刃（２０１）を形成するポンチ貫通打抜き孔（２１０）を設けたものであった。   Conventionally, as shown in FIG. 3, a general punching die (10) for punching a film-like or plate-like punched laminate is composed of a punch (100) and a die (200). In addition, the edge blade (101) was formed, and punch punching holes (210) for forming the edge blade (201) on the outer periphery of the upper end were provided at positions corresponding to the punches of the die.

しかしながら、上述の従来の打抜き型の場合には、物性が異なる構成材料を積層する積層体、特に、外層が中間層より伸びやすい構成材料が積層された積層体又は中間層が外層より伸びやすい構成材料が積層された積層体（２０）を、図４（ａ）に示すように、ダイス（２００）上に押さえ（３００）で固定してポンチ（１００）を下降させて打ち抜いたときに、積層体の打ち抜いた内周断面に抜きバリ（２２）が発生し、この抜きバリ（２２）は、図４（ｂ）に示すように、ポンチ（１００）を上昇させて打抜きを完了したとき、積層体（２０）の打ち抜いた内周断面にそのまま残存してしまうものであった。このため、打ち抜いたときに、出来るだけ抜きバリが発生しないように、例えば、図６に示すように、ポンチ（１００）の下面に凹状部（１３０）を形成して、その外周に山状エッジ刃（１０６）を形成し、また、ダイス（２００）のポンチ貫通打抜き孔（２１０）の上端外周縁部に、突状の山状エッジ（２０２）を形成して、抜きの切れを向上させるようにした打抜き型（１０）が使用されていた。しかし、この打抜き型は、刃が鋭利であるため、磨耗による刃こぼれなどの耐久性における問題を生じた。   However, in the case of the conventional punching die described above, a laminate in which constituent materials having different physical properties are laminated, in particular, a laminate in which a constituent material in which the outer layer is more easily extended than the intermediate layer or an intermediate layer is more easily extended than the outer layer. As shown in FIG. 4 (a), the laminate (20) in which the materials are laminated is fixed on the die (200) with a presser (300) and the punch (100) is lowered and punched. As shown in FIG. 4 (b), when the punching is completed by punching the punch (100), the punching burrs (22) are generated on the inner peripheral section of the body. It was left as it was on the inner peripheral cross-section of the body (20). For this reason, in order to prevent punching burrs as much as possible when punched, for example, as shown in FIG. 6, a concave portion (130) is formed on the lower surface of the punch (100), and a crest edge is formed on the outer periphery thereof. A blade (106) is formed, and a protruding chevron edge (202) is formed on the outer peripheral edge of the upper end of the punch through punching hole (210) of the die (200) so as to improve the cutting of the punch. A punching die (10) was used. However, since this blade has a sharp blade, it has a problem in durability such as blade spillage due to wear.

本発明は、上述の従来の打抜き型における問題点を解決したものであり、物性が異なる構成材料を積層する積層体を打ち抜いたときに、打ち抜いた内周断面に抜きバリの残存が極めて少なく、また、耐久性が良好な打抜き型を提供するものである。   The present invention is a solution to the above-described problems in the conventional punching die, and when punching out a laminate in which constituent materials having different physical properties are punched, there is very little residual burrs in the punched inner peripheral cross section, It also provides a punching die having good durability.

すなわち、本発明の第１の発明は、物性が異なる構成材料を積層する積層体を、ポンチとダイスとにより打ち抜きする打抜き型において、ポンチの下端の外周にエッジ刃を形成し、このエッジ刃の上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃をもつ溝刃を形成し、かつダイスのポンチ対応位置に、上端外周にエッジ刃をもつポンチ貫通打抜き孔を形成したことを特徴とする打抜き型である。   That is, according to a first aspect of the present invention, an edge blade is formed on the outer periphery of the lower end of the punch in a punching die in which a laminated body in which constituent materials having different physical properties are stacked is punched with a punch and a die. A groove blade having an edge blade on the lower outer periphery and an edge blade on the upper outer periphery is formed at the upper position, and a punch through punching hole having an edge blade on the upper outer periphery is formed at the punch corresponding position of the die. It is a punching die.

次に、本発明の第２の発明は、物性が異なる構成材料を積層する積層体を、ポンチとダイスとにより打ち抜きする打抜き型において、ポンチの下端の外周にエッジ刃を形成し、このエッジ刃の近接上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃をもつ溝刃を形成し、かつダイスのポンチ対応位置に、上端外周にエッジ刃をもつポンチ貫通打抜き孔を形成したことを特徴とする打抜き型である。   Next, according to a second aspect of the present invention, an edge blade is formed on the outer periphery of the lower end of the punch in a punching die for punching a laminate in which constituent materials having different physical properties are stacked with a punch and a die. A grooved blade with an edge blade on the lower outer periphery and an edge blade on the upper outer periphery was formed at a position near the upper edge of the die, and a punch through punching hole with an edge blade on the upper end outer periphery was formed at the punch corresponding position of the die. It is a featured punching die.

次に、本発明の第３の発明は、物性が異なる構成材料を積層する積層体を、ポンチとダイスとにより打ち抜きする打抜き型において、ポンチの下端の外周にエッジ刃を形成し、このエッジ刃の近接上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃をもつ溝刃を形成し、この溝刃の近接上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃
をもつ溝刃を形成し、かつダイスのポンチ対応位置に、上端外周にエッジ刃をもつポンチ貫通打抜き孔を形成したことを特徴とする打抜き型である。 Next, according to a third aspect of the present invention, an edge blade is formed on the outer periphery of the lower end of the punch in a punching die for punching a laminate in which constituent materials having different physical properties are stacked with a punch and a die. A groove blade having an edge blade on the lower outer periphery and having an edge blade on the upper outer periphery is formed at a position close to the upper edge of the groove, and a groove having an edge blade on the lower outer periphery and an edge blade on the upper outer periphery in the position near the groove. The punching die is characterized in that a punch is formed and a punch through punching hole having an edge blade on the outer periphery of the upper end is formed at a punch corresponding position of the die.

そして、本発明の第４の発明は、物性が異なる構成材料を積層する積層体を、ポンチとダイスとにより打ち抜きする打抜き型において、ポンチの下面に凹状部を形成し、この凹状部の外周に垂直断面形状が逆直角三角形の山状エッジ刃を形成し、この山状エッジ刃の近接上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃をもつ溝刃を形成し、かつダイスのポンチ対応位置に、上端外周にエッジ刃をもつポンチ貫通打抜き孔を形成したことを特徴とする打抜き型である。   A fourth invention of the present invention is a punching die for punching a laminate in which constituent materials having different physical properties are stacked with a punch and a die, and forming a concave portion on the lower surface of the punch, and on the outer periphery of the concave portion. A chevron edge blade having an inverted right-angled triangle is formed, and a groove blade having an edge blade on the lower outer periphery and an edge blade on the upper outer periphery is formed at a position close to the upper edge of the chevron edge blade. The punching die is characterized in that a punch through punching hole having an edge blade on the outer periphery of the upper end is formed at a punch corresponding position.

本発明の打抜き型は、ポンチの下端の外周に形成されたエッジ刃の上方位置に、下方外周にエッジ刃をもち上方外周にエッジ刃をもつ溝刃を形成するものである。そして、本発明の打抜き型で、物性が異なる構成材料を積層する抜きバリが発生し易い積層体を打ち抜くときに、図２（ａ）に示すように、積層体（２０）をダイス（２００）上に押さえ（３００）で固定してポンチ（１００）を下降させて、ポンチの下端の外周に形成されたエッジ刃（１０１）とダイスのポンチ貫通打抜き孔（２１０）の上端外周に形成されたエッジ刃（２０１）とで積層体を打ち抜くと、積層体の打ち抜いた内周断面に抜きバリ（２２）が発生することがある。しかし、この抜きバリは、下降するポンチの溝刃（１１０）の上方外周に形成されたエッジ刃（１０３）によって、ある程度除去され、この除去された抜きバリ（２３）は、溝刃の溝に溜まる。さらに、図２（ｂ）に示すように、ポンチ（１００）を上昇させて打抜きを完了するときに、除去されずに残った抜きバリが、溝刃（１１０）の下方外周に形成されたエッジ刃（１０２）によって除去され、この除去された抜きバリ（２３）は、溝刃の溝に溜まる。この結果、積層体の打ち抜いた内周断面には、打ち抜きにより発生した抜きバリの残存が極めて少なくなる。なお、図２（ｂ）に示すように、打ち抜かれた部分（２１）は、ダイス（２００）のポンチ貫通打抜き孔（２１０）から下方へ排除される。   The punching die of the present invention forms a groove blade having an edge blade on the lower outer periphery and an edge blade on the upper outer periphery at an upper position of the edge blade formed on the outer periphery of the lower end of the punch. And when punching the laminated body which is easy to generate | occur | produce the punching burr which laminates | stacks the structural material from which a physical property differs with the punching die of this invention, as shown to Fig.2 (a), a laminated body (20) is dice | dies (200). The punch (100) is lowered by fixing with a presser (300) on the top, and the edge blade (101) formed on the outer periphery of the lower end of the punch and the upper end outer periphery of the punch through punching hole (210) of the die are formed. When the laminated body is punched with the edge blade (201), a burr (22) may be generated on the inner peripheral cross-section of the laminated body.

Furthermore, as shown in FIG. 2B, when punching is completed by raising the punch (100), the punching burrs remaining without being removed are edges formed on the lower outer periphery of the groove blade (110). The removed burr (23) removed by the blade (102) accumulates in the groove of the groove blade. As a result, there are very few residual burrs generated by punching in the inner peripheral cross-section of the laminate. In addition, as shown in FIG.2 (b), the punched part (21) is excluded below from the punch penetration hole (210) of die | dye (200).

また、本発明の打抜き型（１０）のポンチ（１００）に設けられる溝刃（１１０）は、図１に示すように、下方外周にエッジ刃（１０２）を形成し、上方外周にエッジ刃（１０３）を形成するものであり、特には鋭利な刃でないため、磨耗に対して耐久性がある。   Further, the groove blade (110) provided in the punch (100) of the punching die (10) of the present invention forms an edge blade (102) on the lower outer periphery and an edge blade (102) on the upper outer periphery as shown in FIG. 103), and is not particularly sharp blades and is durable against wear.

水平な外周にエッジ刃（１０１）を形成し、このエッジ刃の近接上方位置に、下方外周にエッジ刃（１０２）をもち上方外周にエッジ刃（１０３）をもつ水平な溝刃（１１０）を形成するものであり、図２（ａ）に示すように、ダイス（２００）上に押さえ（３００）で固定された積層体（２０）に、ポンチ（１０）が下降するときに、ポンチの下端の外周に形成されたエッジ刃（１０１）とダイス（２００）のポンチ貫通打抜き孔（２１０）の上端外周に形成されたエッジ刃（２０１）とで積層体が打ち抜かれ、また、積層体の打ち抜いた内周断面に発生した抜きバリ（２２）が、下降するポンチの溝刃（１１０）の上方外周に形成されたエッジ刃（１０３）によって、ある程度除去される。そして、図２（ｂ）に示すように、ポンチ（１０）が上昇するときに、除去されずに残った抜きバリが、さらに、溝刃（１１０）の下方外周に形成されたエッジ刃（１０２）によって除去される。なお、除去された抜きバリ（２３）は、溝刃の溝に溜まる。 As shown in FIG. 1, the punch (100) of the first embodiment has an edge blade (101) formed on the horizontal outer periphery of the lower end of a right circular cylinder punch, and a lower outer periphery at a position close to the edge blade. A horizontal groove blade (110) having an edge blade (102) and an edge blade (103) on the upper outer periphery is formed on the die (200) as shown in FIG. When the punch (10) descends to the laminated body (20) fixed by 300), the edge blade (101) formed on the outer periphery of the lower end of the punch and the punch through punching hole (210) of the die (200) The laminated body is punched with the edge blade (201) formed on the outer periphery of the upper end of the punch, and the punching burrs (22) generated in the inner peripheral section punched out of the laminated body are lowered in the groove blade (110) of the punch. Edge blade (1 By 3), it is removed to some extent. Then, as shown in FIG. 2 (b), when the punch (10) is raised, the punching burrs remaining without being removed are further edge blades (102) formed on the lower outer periphery of the groove blade (110). ). The removed burr (23) removed is accumulated in the groove of the groove blade.

実施形態２のポンチ（１００）の構造は、図５（ａ）に示すように、直円柱のポンチの下端の水平な外周にエッジ刃（１０１）を形成し、このエッジ刃の近接上方位置に、下方外周にエッジ刃（１０２）をもち上方外周にエッジ刃（１０３）をもつ水平な溝刃（１１０）を形成し、さらに、この溝刃の近接上方位置に、下方外周にエッジ刃（１０４）をもち上方外周にエッジ刃（１０５）をもつ水平な溝刃（１２０）を形成するものである。この溝刃を二段形成するポンチは、ダイス上に押さえで固定された積層体に、ポンチが下降するときに、ポンチの下端の外周に形成されたエッジ刃とダイスのポンチ貫通打抜き孔の上端外周に形成されたエッジ刃とで積層体が打ち抜かれ、また、積層体の打ち抜いた内周断面に発生した抜きバリが、下降するポンチの一段目の溝刃（１１０）の上方外周に形成されたエッジ刃（１０３）と二段目の溝刃（１２０）の上方外周に形成されたエッジ刃（１０５）によって、ある程度除去される。そして、ポンチが上昇するときに、除去されずに残った抜きバリが、さらに、二段目の溝刃（１２０）の下方外周に形成されたエッジ刃（１０４）と一段目の溝刃（１１０）の下方外周に形成されたエッジ刃（１０２）によって除去される。この結果、実施形態１よりさらに抜きバリの残存が少なくなる。   As shown in FIG. 5 (a), the punch (100) according to the second embodiment has an edge blade (101) formed on the horizontal outer periphery of the lower end of a right circular cylinder punch, and is positioned close to the edge blade. A horizontal groove blade (110) having an edge blade (102) on the lower outer periphery and an edge blade (103) on the upper outer periphery is formed, and an edge blade (104 on the lower outer periphery is located at a position close to the groove blade. ) And a horizontal groove blade (120) having an edge blade (105) on the upper outer periphery. The punch that forms this groove blade in two stages is an edge blade formed on the outer periphery of the lower end of the punch and the upper end of the punch through punching hole of the die when the punch descends to the laminated body fixed by pressing on the die. The laminated body is punched by the edge blade formed on the outer periphery, and the punching burr generated in the inner peripheral section punched out of the laminated body is formed on the upper outer periphery of the first-stage groove blade (110) of the descending punch. The edge blade (103) and the edge blade (105) formed on the upper outer periphery of the second groove blade (120) are removed to some extent. When the punch is raised, the remaining burr that has not been removed is further separated into the edge blade (104) formed on the lower outer periphery of the second-stage groove blade (120) and the first-stage groove blade (110). ) Is removed by the edge blade (102) formed on the lower outer periphery. As a result, there are fewer remaining burrs than in the first embodiment.

実施形態３のポンチ（１００）の構造は、図５（ｂ）に示すように、直円柱のポンチの下面に凹状部（１３０）を形成し、この凹状部の外周に垂直断面形状が逆直角三角形の水平な山状エッジ刃（１０６）を形成し、この山状エッジ刃の近接上方位置に、下方外周にエッジ刃（１０２）をもち上方外周にエッジ刃（１０３）をもつ水平な溝刃（１１０）を形成するものである。このポンチは、ダイス上に押さえで固定された積層体に、ポンチが下降するときに、ポンチの下端の外周に形成された山状エッジ刃とダイスのポンチ貫通打抜き孔の上端外周に形成されたエッジ刃とで積層体が打ち抜かれ、また、積層体の打ち抜いた内周断面に発生した抜きバリが、下降するポンチの溝刃（１１０）の上方外周に形成されたエッジ刃（１０３）によって、ある程度除去される。そして、ポンチ（１０）が上昇するときに、除去されずに残った抜きバリが、さらに、溝刃（１１０）の下方外周に形成されたエッジ刃（１０２）によって除去される。また、ポンチの下端の外周に刃が鋭利な山状エッジ刃が形成されているため、抜きの切れが良好である。   In the structure of the punch (100) of the third embodiment, as shown in FIG. 5 (b), a concave portion (130) is formed on the lower surface of a right circular cylinder punch, and the vertical cross-sectional shape is an inverted right angle on the outer periphery of the concave portion.
