Description

本発明は、パンチング装置用型合わせセット、パンチング装置の型合わせ方法及びプレス製品の製造方法に関する。   The present invention relates to a die set for a punching device, a die matching method for a punching device, and a method for manufacturing a pressed product.

従来のパンチング装置は、雌型を有するダイと、この雌型に合致する形状の雄型を先端に有するパンチとを有し、前記パンチをダイに近接移動させることで雄型及び雌型によってワークを穿設する。この種のパンチング装置にあっては、上記穿設の前に、前記雄型及び雌型の調心作業が行われる（特許第２８８８４２９号公報参照）。   A conventional punching apparatus has a die having a female die and a punch having a male die at the tip that matches the female die, and the workpiece is moved by the male die and the female die by moving the punch close to the die. To drill. In this type of punching device, the alignment operation of the male and female dies is performed before the drilling (see Japanese Patent No. 2888429).

穿設する形状が非円形である場合、パンチの移動方向と垂直な平面における位置ずれの修正（調心）だけではなく、雄型及び雌型の角度ズレの修正を行う必要がある。しかし、上記公報所載の装置にあっては、パンチ及びダイの相対位置を調整して上記調心だけではなく角度ズレの修正も行うことは困難であり、正確な型合わせ作業に長時間を要するという不都合がある。   When the shape to be drilled is non-circular, it is necessary to correct not only misalignment (alignment) in a plane perpendicular to the moving direction of the punch, but also correct the angular deviation between the male and female dies. However, in the apparatus described in the above publication, it is difficult to adjust the relative positions of the punch and the die so as to correct not only the alignment but also the angle deviation. There is an inconvenience that it takes.

特許第２８８８４２９号公報参照See Japanese Patent No. 2888429

本発明は、このような事情に基づいてなされたものであり、本発明の課題は、パンチング装置による抜き形状が非円形であっても正確かつ容易に型合わせができるパンチング装置用型合わせセット及びパンチング装置の型合わせ方法を提供すること、並びに非円形の抜き形状のプレス製品を容易かつ確実に製造できるプレス製品の製造方法を提供することにある。   The present invention has been made based on such circumstances, and an object of the present invention is to provide a punching device die set that can be accurately and easily matched even if the punching shape of the punching device is non-circular. An object of the present invention is to provide a die matching method for a punching apparatus and to provide a method for producing a press product that can easily and reliably produce a non-circular punched press product.

前記課題を解決すべくなされた本発明に係るパンチング装置用型合わせセットは、一方側にダイ装着凹部を有するダイ装着具、一方側に雌型を有するダイ、前記雌型に合致する形状の雄型を先端に有し、前記ダイ装着凹部に装着された前記ダイに相対的に近接移動することでワークを穿設するパンチ、及び前記ダイ装着凹部に装着可能に設けられ、上面に軸合わせ用凹部を有する軸合わせ治具を備え、前記軸合わせ用凹部の前記パンチの移動方向との仮想垂直面における位置が、前記雌型に対応する位置に配され、前記ダイ装着凹部が、前記パンチの移動方向を中心軸として前記ダイを回動可能に装着できるよう設けられている。   The die set for a punching apparatus according to the present invention, which has been made to solve the above problems, includes a die mounting tool having a die mounting recess on one side, a die having a female mold on one side, and a male having a shape matching the female mold. A punch that has a die at the tip and moves relatively close to the die mounted in the die mounting recess, and is provided so as to be mountable in the die mounting recess, and has an upper surface for axis alignment. An axis alignment jig having a recess, the position of the axis alignment recess in a virtual vertical plane with respect to the movement direction of the punch is arranged at a position corresponding to the female mold, and the die mounting recess is It is provided so that the die can be rotatably mounted with the moving direction as a central axis.

当該パンチング装置用型合わせセットを用いることで、前記パンチの移動方向と垂直方向における雄型及び雌型の位置ズレと、前記パンチの移動方向を中心軸とする回転方向における雄型及び雌型の角度ズレとを容易かつ確実に修正することができる。つまり、まずダイ装着凹部に軸合わせ治具を装着し、パンチをこの軸合わせ治具に近接させることで、軸合わせ治具の軸合わせ用凹部が雌型に対応する位置に設けられているので、前記移動方向と垂直方向における前記パンチの位置を容易かつ確実に合わせることができる。その後、ダイ装着凹部に軸合わせ治具に代えてダイを装着し、パンチをこのダイに近接させ、ダイ装着凹部に装着されたダイを回動することで、前記雄型及び雌型の角度ズレを修正することができる。   By using the die set for punching apparatus, the male and female dies are displaced in the direction perpendicular to the punch moving direction, and the male and female dies in the rotational direction centered on the moving direction of the punch. The angle deviation can be easily and reliably corrected. In other words, the axis alignment jig is first installed in the die mounting recess, and the punch is brought close to the axis alignment jig so that the axis alignment recess of the axis alignment jig is provided at a position corresponding to the female die. The position of the punch in the direction perpendicular to the moving direction can be easily and reliably aligned. After that, the die is mounted in the die mounting recess instead of the axis alignment jig, the punch is brought close to this die, and the die mounted in the die mounting recess is rotated, whereby the angular displacement between the male mold and the female mold is achieved.

It is preferable that the axis alignment recess has a shape that matches the base portion. Thereby, by using the base part and the concave part for axis alignment, it is possible to more easily and reliably align the punches in the moving direction and the vertical direction. In other words, the positioning can be performed easily and reliably by correcting the relative position of the punch in the direction perpendicular to the movement direction so that the base portion of the punch matches the axis alignment recess. .

After the step of aligning the relative position of the punch in the direction perpendicular to the movement direction with respect to the die mounting tool and the positioning step, the axis alignment jig is removed from the die mounting recess, and the die mounting recess is moved to the die mounting recess. And a step of correcting the angular misalignment between the male mold and the female mold by rotating the die mounted in the die mounting recess.

当該パンチング装置の型合わせ方法は、前記パンチの移動方向と垂直方向における雄型及び雌型の位置ズレと、前記パンチの移動方向を中心軸とする回転方向における雄型及び雌型の角度ズレとを容易かつ確実に修正することができる。   The die matching method of the punching apparatus includes a positional deviation between the male mold and the female mold in a direction perpendicular to the movement direction of the punch, and an angular deviation between the male mold and the female mold in a rotation direction with the movement direction of the punch as a central axis. Can be easily and reliably corrected.

当該プレス製品の製造方法は、当該パンチング装置の型合わせ方法によって型合わせを行う工程と、この型合わせを行った後に前記パンチ及びダイによってワークを穿設する工程とを有する。   The manufacturing method of the press product includes a step of performing die matching by the die matching method of the punching apparatus, and a step of punching a workpiece with the punch and die after performing the die matching.

当該プレス製品の製造方法によれば、当該パンチング装置の型合わせ方法によって容易かつ確実に雄型及び雌型の型合わせがなされるため、容易かつ確実にプレス製品を製造することができる。   According to the manufacturing method of the press product, since the male mold and the female mold are easily and reliably matched by the mold matching method of the punching apparatus, the press product can be manufactured easily and reliably.

The punch 10 has a male die 11 (unshaped cutting edge) at the tip (lower end), and a base 12 above the male die 11. In this embodiment, the punch 10 side (one side of the claims) is referred to as the upper side, and the die attachment tool 40 side is referred to as the lower side.

前記パンチ１０は、穿設作業のためにパンチ１０を上下動させるパンチング装置のパンチ保持機構（図示省略）によって保持される。このパンチ保持機構は、穿設作業のためにパンチ１０を前述のように上下動させる機構と、ダイ装着具４０に対するパンチ１０の相対的な水平方向における位置（パンチ１０の移動方向と仮想垂直面におけるパンチ１０の位置）を修正する機構（図示省略）とを有している。つまり、パンチ１０は、前記パンチ保持機構の前記水平方向位置修正機構によって水平方向の位置が修正されると共に、前記上下動機構によって穿設作業のための上下動を行う。また、パンチ１０は、後述する基台部１２の上方で前記パンチ保持機構に保持される。なお、本実施形態において、パンチの移動方向とは上下方向（鉛直方向）である。また、パンチング装置は、前記ダイ保持具４０を水平方向に移動させることで、ダイ装着具４０に対するパンチ１０の相対的な位置を修正する機構を備えることも可能である。なお、パンチング装置は、前述のようなパンチ１０とダイ装着具４０との相対的な位置を修正する機構として、パンチ１０及びダイ装着具４０のいずれか一方又は双方を移動させる機構を有することができる。   The punch 10 is held by a punch holding mechanism (not shown) of a punching device that moves the punch 10 up and down for drilling work. This punch holding mechanism includes a mechanism for moving the punch 10 up and down as described above for the drilling operation, and a position of the punch 10 relative to the die mounting tool 40 in the horizontal direction (moving direction of the punch 10 and virtual vertical plane). And a mechanism (not shown) for correcting the position of the punch 10 in FIG. That is, the punch 10 has its horizontal position corrected by the horizontal position correcting mechanism of the punch holding mechanism and moved up and down for drilling by the vertical movement mechanism. Further, the punch 10 is held by the punch holding mechanism above a base portion 12 described later. In this embodiment, the moving direction of the punch is the vertical direction (vertical direction). Further, the punching device may include a mechanism for correcting the relative position of the punch 10 with respect to the die mounting tool 40 by moving the die holding tool 40 in the horizontal direction. The punching device may have a mechanism for moving one or both of the punch 10 and the die mounting tool 40 as a mechanism for correcting the relative position between the punch 10 and the die mounting tool 40 as described above. it can.

前記雄型１１は、後述する雌型２１に合致した形状をなし、底面視非円形である。つまり、前記パンチ１０とダイ２０とによって、ワークには非円形の穿孔が形成される。   The male mold 11 has a shape that matches a female mold 21 described later, and is non-circular in a bottom view. That is, the punch 10 and the die 20 form a non-circular perforation in the workpiece.

前記パンチ１０は、鉛直方向（前記移動方向）を中心軸とすると共に前記雄型１１よりも径が大きい円柱状の基台部１２を前記雄型１１の一方側に有している。ここで、基台部１２の径が雄型１１より大きいとは、底面視（パンチ１０の先端から見た状態）で基台部１２の外形内に雄型１１の外形が含まれていることを意味する。さらに言及すると、本実施形態においては、雄型１１の図心軸と基台部１２の中心軸とが一致しており、底面視において雄型１１の外接円の径が基台部１２の径よりも小さい。   The punch 10 has a cylindrical base portion 12 on one side of the male die 11 having a vertical direction (the moving direction) as a central axis and a diameter larger than that of the male die 11. Here, the diameter of the base portion 12 is larger than the male die 11 that the outer shape of the male die 11 is included in the outer shape of the base portion 12 in a bottom view (as viewed from the tip of the punch 10). Means. Further, in this embodiment, the centroid axis of the male mold 11 and the center axis of the base section 12 coincide with each other, and the diameter of the circumscribed circle of the male mold 11 in the bottom view is the diameter of the base section 12. Smaller than.

（ダイ）
前記ダイ２０は、前記ダイ装着具４０に装着され、前記パンチ１０とによってワークを穿設する部材である。このダイ２０は、鉛直方向を中心軸として前記ダイ装着具４０に回動可能に装着される。具体的には、ダイ２０の外形は、鉛直方向を中心軸とした円柱状である。ダイ２０の外形の中心軸は、水平方向における正確な位置にある前記パンチ１０の基台部１２の中心軸、及び前記雄型１１の図心軸と一致している。なお、パンチ１０の水平方向における正確な位置とは、前記雄型１１と後述する雌型２１との図心軸が一致する
パンチ１０の位置を意味する。なお、図心軸が一致するとは完全に一致する場合のみならず、加工精度によっては多少のズレがあってもよい。 (Die)
The die 20 is a member that is mounted on the die mounting tool 40 and punches a workpiece with the punch 10. The die 20 is rotatably mounted on the die mounting tool 40 with the vertical direction as a central axis. Specifically, the outer shape of the die 20 has a cylindrical shape with the vertical direction as the central axis. The center axis of the outer shape of the die 20 coincides with the center axis of the base portion 12 of the punch 10 and the centroid axis of the male die 11 at an accurate position in the horizontal direction. The exact position of the punch 10 in the horizontal direction means the position of the punch 10 where the centroid axes of the male mold 11 and the female mold 21 described later coincide. It should be noted that the fact that the centroids coincide not only completely coincides but also there may be some deviation depending on the machining accuracy.

前記ダイ２０は、前述のように雄型１１に合致した形状の雌型２１（異形状切削切刃部）を、上面に有している。この雌型２１は、雄型１１とせん断加工隙間を確保しつつ雄型１１と一致した形状を有する。なお、雌型２１は上面に設けられた凹部から構成され、この上面の雌型２１を除いた領域は平坦面である。   As described above, the die 20 has the female die 21 (unshaped cutting edge portion) having a shape matching the male die 11 on the upper surface. The female mold 21 has a shape that matches the male mold 11 while ensuring a shearing clearance with the male mold 11. The female die 21 is composed of a recess provided on the upper surface, and the region on the upper surface excluding the female die 21 is a flat surface.

（ダイ装着具）
前記ダイ装着具４０は、前述のようにダイ２０が装着されるダイ装着凹部４１を上面に有している。なお、この上面のダイ装着凹部４１を除いた領域は平坦面である。 (Die mounting tool)
The die mounting tool 40 has a die mounting recess 41 on the top surface to which the die 20 is mounted as described above. In addition, the area | region except the die mounting recessed part 41 of this upper surface is a flat surface.

前記ダイ装着凹部４１は、前述のようにダイ２０が装着できると共に、前記軸合わせ治具３０が装着できる。このダイ装着凹部４１は、前記ダイ２０を回動可能に装着できるよう設けられている。具体的には、ダイ装着凹部４１の内周壁は、鉛直方向を中心軸とする円柱状に設けられている。このダイ装着凹部４１の内周壁の中心軸は、ダイ２０の外形の中心軸と一致し、ダイ装着凹部４１の内周壁の径は、ダイ２０の外形の径よりも少しだけ大きい。このダイ装着凹部４１の内周壁の径とダイ２０の外形の径との差は、前述のようにダイ２０を回動できると共にダイ２０の水平方向に許容される以上の位置ズレを生じない範囲とされ、ワークや穿孔の大きさによって異なるが、例えば１μｍ以下である。さらに、ダイ装着凹部４１の内周壁は、完全な円柱状でなくとも良く、例えば内周壁に鉛直方向に沿って空気抜き等のための溝を設けることも可能である。   The die mounting recess 41 can mount the die 20 as described above, and can mount the axis alignment jig 30. The die mounting recess 41 is provided so that the die 20 can be rotatably mounted. Specifically, the inner peripheral wall of the die mounting recess 41 is provided in a cylindrical shape with the vertical direction as the central axis. The central axis of the inner peripheral wall of the die mounting concave portion 41 coincides with the central axis of the outer shape of the die 20, and the diameter of the inner peripheral wall of the die mounting concave portion 41 is slightly larger than the outer diameter of the die 20. The difference between the diameter of the inner peripheral wall of the die mounting recess 41 and the diameter of the outer shape of the die 20 is a range in which the die 20 can be rotated as described above and the positional deviation beyond the allowable horizontal direction of the die 20 does not occur. For example, it is 1 μm or less, although it varies depending on the size of the workpiece and the perforation. Further, the inner peripheral wall of the die mounting recess 41 does not have to be a complete columnar shape. For example, a groove for venting air or the like can be provided in the inner peripheral wall along the vertical direction.

なお、前記ダイ装着具４０は、ダイ装着凹部４１に装着されたダイ２０を回動不能に保持する固定機構（図示省略）を備えることも可能である。つまり、ダイ装着凹部４１にダイ２０を装着し、ダイ２０を回動して雄型１１と雌型２１との角度ズレを後述するように修正した後、前記固定機構によってダイ２０の回動を規制することも可能である。   The die mounting tool 40 can also include a fixing mechanism (not shown) that holds the die 20 mounted in the die mounting recess 41 in a non-rotatable manner. That is, after the die 20 is mounted in the die mounting recess 41 and the die 20 is rotated to correct the angle deviation between the male mold 11 and the female mold 21 as described later, the die 20 is rotated by the fixing mechanism. It is also possible to regulate.

（軸合わせ治具）
前記軸合わせ治具３０は、前述のようにダイ装着凹部４１に装着可能に設けられ、この軸合わせ治具３０の外形は、前記ダイ２０と同様の形状とされている。 (Axis alignment jig)
The axis alignment jig 30 is provided so as to be attachable to the die mounting recess 41 as described above, and the outer shape of the axis alignment jig 30 is the same as that of the die 20.

前記軸合わせ治具３０は、上面に軸合わせ用凹部３１を有している。この軸合わせ用凹部３１は、水平方向において前記ダイ２０の雌型２１に対応する位置に設けられている。具体的には、この軸合わせ用凹部３１は、水平方向における正確な位置にあるパンチ１０（の基台部１２）の挿入を許容する位置に設けられている。また、軸合わせ用凹部３１は、水平方向における正確な位置にパンチ１０が存在しない場合、このパンチ１０の挿入を許容しないよう設けられている。   The axis alignment jig 30 has an axis alignment recess 31 on the upper surface. The axial alignment recess 31 is provided at a position corresponding to the female die 21 of the die 20 in the horizontal direction. Specifically, the recess 31 for axial alignment is provided at a position that allows insertion of the punch 10 (the base portion 12) at an accurate position in the horizontal direction. Further, the axial alignment recess 31 is provided so as not to allow the punch 10 to be inserted when the punch 10 does not exist at an accurate position in the horizontal direction.

前記軸合わせ用凹部３１の内周壁は、前記パンチ１０の基台部１２の外形に対応した形状に設けられている。具体的には、軸合わせ用凹部３１の内周壁は、鉛直方向を中心軸とする円柱状に設けられている。この軸合わせ用凹部３１の内周壁の中心軸は、水平方向における正確な位置にあるパンチ１０の基台部１２の中心軸と一致し、軸合わせ用凹部３１の内周壁の径は、基台部１２の外形の径よりも少しだけ大きい。このため、前記ダイ装着凹部４１に軸合わせ治具３０が装着された状態で、軸合わせ用凹部３１にパンチ１０の基台部１２を挿入することで、パンチ１０の移動方向との仮想垂直面における位置が正確であることを確認することができる。なお、軸合わせ用凹部３１の内周壁の径と基台部１２の外形の径との差は、ワークの加工精度によって定められ、ワークや穿孔の大きさによって異なるが、例えば１μｍ以下である。   The inner peripheral wall of the recess 31 for axial alignment is provided in a shape corresponding to the outer shape of the base portion 12 of the punch 10. Specifically, the inner peripheral wall of the alignment recess 31 is provided in a columnar shape with the vertical direction as the central axis. The central axis of the inner peripheral wall of the alignment recess 31 coincides with the central axis of the base portion 12 of the punch 10 at an accurate position in the horizontal direction, and the diameter of the inner peripheral wall of the alignment recess 31 is the base It is slightly larger than the outer diameter of the part 12. For this reason, by inserting the base portion 12 of the punch 10 into the axial alignment recess 31 in a state where the axis alignment jig 30 is mounted in the die mounting recess 41, a virtual vertical plane with respect to the moving direction of the punch 10 It can be confirmed that the position at is accurate. The difference between the diameter of the inner peripheral wall of the recess 31 for axis alignment and the diameter of the outer shape of the base 12 is determined by the processing accuracy of the workpiece and varies depending on the size of the workpiece and the hole, but is, for example, 1 μm or less.

前記パンチング装置は、前記パンチ保持機構のほか、ワークを搬送する搬送機構（図示省略）を有する。この搬送機構によってパンチ１０とダイ２０との間にワークが搬送され、この搬送されたワークが前記パンチ１０及びダイ２０によって穿設される。また、前記パンチング装置は、各種機構の動作を制御する制御機構（図示省略）を備えている。 (Punching device)
In addition to the punch holding mechanism, the punching device has a transport mechanism (not shown) for transporting a workpiece. The workpiece is conveyed between the punch 10 and the die 20 by the conveyance mechanism, and the conveyed workpiece is punched by the punch 10 and the die 20. Further, the punching apparatus includes a control mechanism (not shown) that controls the operation of various mechanisms.

さらに、前記パンチング装置は、パンチ１０とその他の部材との相対位置を測定する測定機構（図示省略）を有する。この測定機構としては、例えば顕微鏡が挙げられる。この測定機構は、前記ダイ装着凹部４１に軸合わせ治具３０が装着された状態で前記パンチ１０の基台部１２と軸合わせ用凹部３１との相対位置を撮像し、またダイ装着凹部４１にダイ２０が装着された状態で前記雌型２１と雄型１１との相対位置を撮像する。この測定機構によって測定されたデータは上記制御機構に送られる。   Furthermore, the punching device has a measurement mechanism (not shown) for measuring the relative position between the punch 10 and other members. An example of this measuring mechanism is a microscope. This measuring mechanism images the relative position between the base portion 12 of the punch 10 and the alignment recess 31 in a state where the alignment jig 30 is mounted in the die mounting recess 41, and the die mounting recess 41 The relative position between the female mold 21 and the male mold 11 is imaged in a state where the die 20 is mounted. Data measured by the measurement mechanism is sent to the control mechanism.

It is also possible to rotate the die 20. Note that the die 20 can be manually rotated.

＜プレス製品の製造方法＞
次に、本発明の一実施形態のプレス製品の製造方法について説明する。この製造方法は、前述した当該型合わせセットを用いて型合わせを行う工程と、前記型合わせ工程後に前記パンチ１０及びダイ２０によってワークを穿設する工程とを有する。 <Production method of press products>
Next, the manufacturing method of the press product of one Embodiment of this invention is demonstrated. This manufacturing method includes a step of performing die matching using the die matching set described above, and a step of punching a workpiece with the punch 10 and the die 20 after the die matching step.

（型合わせ工程）
型合わせ工程は、前述した当該型合わせセットを用い、パンチ１０の中心軸を調心する第１工程と、ダイ装着凹部４１の装着物を交換する第２工程と、雄型１１及び雌型２１の角度ズレを修正する第３工程とを有する。なお、この型合わせ方法は、本発明のパンチング装置の型合わせ方法の一実施形態である。 (Mold matching process)
The die matching step uses the die matching set described above, the first step of aligning the center axis of the punch 10, the second step of exchanging the attachment in the die attachment recess 41, the male die 11 and the female die 21. And a third step of correcting the angle deviation. This mold matching method is an embodiment of the mold matching method for the punching apparatus of the present invention.

第１工程は、前記ダイ装着凹部４１に前記軸合わせ治具３０を装着し、この状態で、ダイ装着具４０に対するパンチ１０の相対的な水平方向における位置を合わせる工程である。第１工程においては、まず図２に示すように、ダイ装着凹部４１に軸合わせ治具３０を装着し、この軸合わせ治具３０にパンチ１０を近接させる。そして、パンチ１０の基台部１２が軸合わせ用凹部３１に図３に示すように挿入できるよう、パンチ１０を水平方向に移動させて、水平方向の位置を調整する（調心する）。なお、この水平方向の位置調整に際して、前記測定機構によってパンチ１０の基台部１２と軸合わせ用凹部３１との相対位置を測定することで、上記調心を容易かつ確実に行うことができる。   The first step is a step of mounting the axis alignment jig 30 in the die mounting recess 41 and aligning the position of the punch 10 in the horizontal direction relative to the die mounting tool 40 in this state. In the first step, first, as shown in FIG. 2, the axis alignment jig 30 is mounted in the die mounting recess 41, and the punch 10 is brought close to the axis alignment jig 30. Then, the punch 10 is moved in the horizontal direction so that the base portion 12 of the punch 10 can be inserted into the alignment recess 31 as shown in FIG. 3, and the position in the horizontal direction is adjusted (aligned). When adjusting the position in the horizontal direction, the alignment can be easily and reliably performed by measuring the relative position between the base 12 of the punch 10 and the recess 31 for alignment with the measuring mechanism.

第２工程においては、まずパンチ１０を上方に移動させる。そして、前記ダイ装着凹部４１から前記軸合わせ治具３０を離脱し、このダイ装着凹部４１に前記ダイ２０を装着する（図４参照）。   In the second step, first, the punch 10 is moved upward. Then, the axis alignment jig 30 is detached from the die mounting recess 41, and the die 20 is mounted in the die mounting recess 41 (see FIG. 4).

第３工程は、ダイ装着凹部４１に装着されたダイ２０を回動することで、前述のように雄型１１及び雌型２１の角度ズレを修正する工程である。第３工程においては、まずダイ２０にパンチ１０を近接させて、雄型１１と雌型２１との角度ズレを確認し、ダイ２０を回動させることで、前記角度ズレを修正する（図５参照）。なお、この角度ズレの修正に際して、前記測定機構によって雄型１１及び雌型２１との相対位置を測定することで、上記角度ズレの修正を容易かつ確実に行うことができる。   The third step is a step of correcting the angular misalignment between the male mold 11 and the female mold 21 as described above by rotating the die 20 mounted in the die mounting recess 41. In the third step, first, the punch 10 is brought close to the die 20, the angle deviation between the male mold 11 and the female mold 21 is confirmed, and the die 20 is rotated to correct the angle deviation (FIG. 5). reference). In correcting the angle deviation, the angle deviation can be easily and reliably corrected by measuring the relative position between the male mold 11 and the female mold 21 by the measurement mechanism.

（穿設工程）
穿設工程は、前記型合わせ方法後に前記パンチ１０を上下動することによって、ワークを穿設する工程である。 (Drilling process)
The drilling step is a step of drilling a workpiece by moving the punch 10 up and down after the mold matching method.

＜利点＞
当該型合わせセットを用いることで、まず前記第１工程において軸合わせ治具３０を利用して雄型１１と雌型２１との図心軸を合わせることができ、次にダイ２０を回動させることで雄型１１及び雌型２１の角度ズレ（前記図心軸を中心とする角度ズレ）を修正することができる。このため、雄型１１及び雌型２１の水平方向における位置ズレと、角度ズレとを容易かつ確実に修正することができる。 <Advantages>
By using the mold matching set, first, the centroid axes of the male mold 11 and the female mold 21 can be aligned using the axis alignment jig 30 in the first step, and then the die 20 is rotated. Thus, the angle shift between the male mold 11 and the female mold 21 (the angle shift centered on the centroid axis) can be corrected. For this reason, it is possible to easily and reliably correct the positional deviation and the angular deviation in the horizontal direction of the male mold 11 and the female mold 21.

また、パンチ１０が雄型１１よりも上方かつ大径の基台部１２を有し、軸合わせ用凹部３１が前記基台部１２に合致する形状に設けられているので、前記位置ズレを修正する際（第１工程の際）に、この基台部１２と軸合わせ用凹部３１とを用いることで水平方向における位置ズレをより容易かつ確実に行うことができる。特に、軸合わせ用凹部３１が、軸合わせ治具３０の上面に設けられているので、前記基台部１２と軸合わせ用凹部３１との相対位置が外部から観察しやすい。さらに、雄型２１を観察して軸合わせを行う場合に比べて、前記基台部１２と軸合わせ用凹部３１との相対位置の観察によって軸合わせを行うことができるので、前記水平方向の位置ズレをより容易かつ確実に行うことができる。   Further, since the punch 10 has a base portion 12 that is larger than the male mold 11 and has a large diameter, and the recess 31 for alignment is provided in a shape that matches the base portion 12, the positional deviation is corrected. When this is done (in the first step), the horizontal misalignment can be performed more easily and reliably by using the base 12 and the recess 31 for axis alignment. In particular, since the axis alignment recess 31 is provided on the upper surface of the axis alignment jig 30, the relative position between the base 12 and the axis alignment recess 31 can be easily observed from the outside. Furthermore, compared with the case where the male mold 21 is observed and the axis alignment is performed, the axis alignment can be performed by observing the relative position between the base portion 12 and the axis alignment recess 31, so that the horizontal position Misalignment can be performed more easily and reliably.

本実施形態は前記構成からなり、前述の利点を奏するものであったが、本発明は前記実施形態に限定されるものではなく、本発明の意図する範囲内において適宜設計変更可能である。 [Other Embodiments]
The present embodiment has the above-described configuration and has the above-described advantages. However, the present invention is not limited to the above-described embodiment, and the design can be changed as appropriate within the intended scope of the present invention.

つまり、前記実施形態においては、パンチ１０が鉛直方向を中心軸とすると共に雄型１１より径が大きい円柱状の基台部１２を有するものについて説明したが、本発明は必ずしもこれに限定されるものではない。さらに、パンチ１０が前述のような基台部１２を有する場合であっても、軸合わせ用凹部３１の内周壁が基台部１２の外形と同様に円柱状であるものに限定されるものではない。ただし、軸合わせ用凹部３１が基台部１２の外形に対応した形状であることが好ましい。つまり、軸合わせ用凹部３１が、雄型１１及び雌型２１の図心軸を合わせられるよう基台部１２の外形に対応した形状であることが好ましい。具体的には、例えば軸合わせ用凹部３１が平面視正方形で、軸合わせ用凹部３１の径（正方形の一辺の長さ）が基台部１２の径より若干大きいものであっても良く、これにより、軸合わせ凹部３１と基台部１２との相対位置を観察することで、雄型１１及び雌型２１の図心軸を合わせることができる。   That is, in the above-described embodiment, the punch 10 has the columnar base portion 12 having the vertical direction as the central axis and the diameter larger than that of the male die 11, but the present invention is not necessarily limited thereto. It is not a thing. Further, even when the punch 10 has the base portion 12 as described above, the inner peripheral wall of the shaft alignment recess 31 is not limited to a cylindrical shape like the outer shape of the base portion 12. Absent. However, it is preferable that the alignment recess 31 has a shape corresponding to the outer shape of the base portion 12. That is, it is preferable that the axis alignment recess 31 has a shape corresponding to the outer shape of the base 12 so that the centroid axes of the male mold 11 and the female mold 21 can be aligned. Specifically, for example, the alignment recess 31 may be a square in plan view, and the diameter of the alignment recess 31 (the length of one side of the square) may be slightly larger than the diameter of the base 12. Thus, the centroid axes of the male mold 11 and the female mold 21 can be aligned by observing the relative position between the axis aligning recess 31 and the base 12.

以上説明したように、本発明は、パンチング装置の型合わせを正確かつ容易に行うことができるので、抜き形状が非円形のプレス製品の加工に好適に用いることができる。   As described above, according to the present invention, the punching apparatus can be accurately and easily matched, so that the punching device can be suitably used for processing a non-circular pressed product.
