Description

本発明はプレス打ち抜き装置に関するものであり、特に、プレス打ち抜き装置における抜きかすの排出方法に関するものである。   The present invention relates to a press punching device, and more particularly, to a method for discharging punch chips in a press punching device.

従来の此種プレス打ち抜き装置は、図6に示すように、パンチ1を備えた上型2が上架台3に固定され、該上型2にはパンチ1が貫通する貫通穴(図示せず)を有したストリッパプレート4が取り付けられている。また、前記パンチ1が挿入するパンチ穴5を備えた下型6は下架台7に載置され、前記パンチ1とパンチ穴5が正確に一致するように、上型3に設けたガイドピン8と下型6に設けたガイド穴9により位置合わせが行われた状態で、下架台7にボルトなどで固定されている。   As shown in FIG. 6, in the conventional press punching apparatus, an upper die 2 provided with a punch 1 is fixed to an upper frame 3, and a through hole (not shown) through which the punch 1 passes is formed in the upper die 2. A stripper plate 4 is attached. A lower die 6 having a punch hole 5 into which the punch 1 is inserted is placed on a lower base 7, and guide pins 8 provided on the upper die 3 so that the punch 1 and the punch hole 5 are exactly aligned. In a state where the alignment is performed by the guide hole 9 provided in the lower die 6, the lower die 6 is fixed to the lower base 7 with bolts or the like.

被加工シート材10を打ち抜き加工する場合は、該被加工シート材10を前記上型2と下型6の間に挿入し、図示しない位置決め装置で被加工シート材10を下型6に位置決め載置する。上架台3と一体に上型2を下降させると、先ず、被加工シート材10がストリッパプレート4によって下型6の上面に押さえ付けられ、上型2がさらに下降してパンチ1がストリッパプレート4の貫通穴を貫通し、上型2のパンチ1と下型6のパンチ穴5とのせん断により被加工シート材10が打ち抜かれる。   When the work sheet material 10 is punched, the work sheet material 10 is inserted between the upper mold 2 and the lower mold 6 and the work sheet material 10 is positioned and mounted on the lower mold 6 by a positioning device (not shown). Put. When the upper die 2 is lowered integrally with the upper platform 3, first, the work sheet material 10 is pressed against the upper surface of the lower die 6 by the stripper plate 4, and the upper die 2 is further lowered to bring the punch 1 into the stripper plate 4. The sheet material 10 to be processed is punched out by shearing between the punch 1 of the upper die 2 and the punch hole 5 of the lower die 6.

前記パンチ穴5の下部には大径の逃げ部5aが設けられ、パンチ1で打ち抜かれた抜きかす11は前記パンチ穴5に溜まり、打ち抜き加工の繰り返しによって順次パンチ穴5の下部に押し下げられ、抜きかす11が逃げ部5aに至ったときに、下架台7に設けられているシュート穴12を通って下方に落下する。図示例では被加工シート材10の一箇所を打ち抜いているが、実際には上型2と下型6には複数のパンチ1とパンチ穴5が設けられており、同時に多数の箇所を打ち抜き加工するため、下架台7のシュート穴12の開口部分を大きくとって、多数の抜きかす11を連続的に排出できるように形成されている。   A large-diameter relief portion 5a is provided in the lower portion of the punch hole 5, and the punch 11 punched by the punch 1 is accumulated in the punch hole 5, and is sequentially pushed down to the lower portion of the punch hole 5 by repeated punching. When the scraper 11 reaches the escape portion 5 a, it falls downward through the chute hole 12 provided in the lower base 7. In the example shown in the figure, one part of the sheet material to be processed 10 is punched, but actually, the upper die 2 and the lower die 6 are provided with a plurality of punches 1 and punch holes 5, and a number of points are punched at the same time. For this reason, the opening portion of the chute hole 12 of the undercarriage 7 is made large so that a large number of scums 11 can be continuously discharged.

抜きかすを定期的に排出する機構としては、下型の下部に水平の下溝を形成しておき、下型側面から前記下溝内へプッシャを挿入し、抜きかす(この場合は、打ち抜かれた製品)をプッシャで押し出すようにしたプレス加工用金型が知られている(例えば特許文献1参照)。   As a mechanism for periodically discharging the scraps, a horizontal lower groove is formed in the lower part of the lower mold, and a pusher is inserted into the lower groove from the side of the lower mold and removed (in this case, a punched product) ) Is extruded with a pusher (for example, see Patent Document 1).

また、下型をシリンダで移動させてハケを挿通し、打ち抜き後の残材をハケと押出板でバリ用シュートへ落とし、打ち抜かれた製品を他のハケと取出板で製品用シュートへ落とすように形成した自動プレスも知られている(例えば特許文献2参照)。

Also, move the lower die with a cylinder and insert the brush, drop the remaining material after punching into the burr chute with the brush and the extrusion plate, and drop the punched product into the product chute with the other brush and take-out plate Also known is an automatic press formed in (see, for example, Patent Document 2).

図6に示した従来のプレス打ち抜き装置は、下架台7にシュート穴12の開口部分を大きくとってあり、下型6を支持する部分が少なくなって機械的強度が低下する。このため、図7に示すように、下型6が変形を起こしやすくなる。   In the conventional press punching apparatus shown in FIG. 6, the opening portion of the chute hole 12 is made large in the lower base 7, and the portion supporting the lower die 6 is reduced, so that the mechanical strength is lowered. For this reason, as shown in FIG. 7, the lower mold 6 is likely to be deformed.

下架台7にシュート穴12を開口しなければ機械的強度を維持できるが、抜きかす11が下型6のパンチ穴5内に溜まるため、連続的に多数の打ち抜き加工する場合は、定期的に抜きかす11を排出する必要があり、装置の複雑化あるいは作業の中断による能率低下などの不具合が発生する。   The mechanical strength can be maintained unless the chute hole 12 is opened in the lower base 7, but since the scrap 11 is accumulated in the punch hole 5 of the lower die 6, when a large number of punching processes are continuously performed, It is necessary to discharge the scum 11, which causes problems such as complexity of the apparatus or reduced efficiency due to work interruption.

機械的強度を上げるために下型6の厚みを増加することも考えられるが、下型の重量が増加して段取り変えの際に下型の交換が困難になる。また、厚い材料を加工して下型を製作するので、材料費の上昇と加工工数の増加によりコストアップとなる。   Although it is conceivable to increase the thickness of the lower mold 6 in order to increase the mechanical strength, the weight of the lower mold increases and it becomes difficult to replace the lower mold when changing the setup. Moreover, since the lower mold is manufactured by processing a thick material, the cost increases due to an increase in material cost and an increase in the number of processing steps.

特許文献1および特許文献2の発明は、それぞれに抜きかす(あるいは製品)の排出機構が設けられているが、プッシャやハケを挿入するための空間部を下型に設けなくてはならず、空間部を設けることによって機械的強度が低下するという不具合がある。   The inventions of Patent Document 1 and Patent Document 2 are each provided with a discharge mechanism for removing (or product), but a space for inserting a pusher or brush must be provided in the lower mold, There is a problem that the mechanical strength is lowered by providing the space.

そこで、本発明は、下型を支持する下架台にシュート穴を開口せずに機械的強度を向上させ、かつ、簡易な構成で抜きかすを排出できるようにしたプレス打ち抜き装置を提供することを目的とする。   Accordingly, the present invention provides a press punching device that improves mechanical strength without opening a chute hole in the undercarriage that supports the lower mold, and that can discharge the scraps with a simple configuration. Objective.

本発明は上記目的を達成するために提案されたものであり、請求項1記載の発明は、パンチを備えた上型と、前記パンチが挿入するパンチ穴を備えた下型とからなるプレス打ち抜き装置において、平板状の下架台に前記下型を上下動可能に載置し、該下型の上昇時に前記下架台と下型との間にハケを挿入して抜きかすを排出するように形成したことを特徴とするプレス打ち抜き装置を提供する。   The present invention has been proposed to achieve the above object, and the invention according to claim 1 is a press punching comprising an upper die provided with a punch and a lower die provided with a punch hole into which the punch is inserted. In the apparatus, the lower mold is mounted on a flat plate-like base so that it can be moved up and down, and a brush is inserted between the lower base and the lower mold when the lower mold is lifted to discharge the scraps. A press punching device is provided.

この構成によれば、下型は上下動可能であり、下型を下降させて下架台に載置した状態で被加工シート材を打ち抜く。打ち抜かれた抜きかすは下型のパンチ穴の途中に溜まるか、あるいは、落下して下架台の上面に溜まる。1回打ち抜いた後または数回打ち抜いた後に、上型を上昇するとともに下型を上昇させ、下架台と下型との間にできた空間部にハケを挿入して抜きかすを排出する。抜きかすを排出した後は、ハケを取り出して下型を下降させ、下型を下架台に載置した状態で再び打ち抜き作業に戻る。   According to this configuration, the lower die can be moved up and down, and the processed sheet material is punched in a state where the lower die is lowered and placed on the gantry. The punched punch is accumulated in the middle of the punch hole of the lower die, or falls and accumulates on the upper surface of the undercarriage. After punching once or punching several times, the upper die is raised and the lower die is raised, and a brush is inserted into the space formed between the lower base and the lower die to discharge the scraps. After discharging the scraps, the brush is taken out, the lower die is lowered, and the punching operation is resumed with the lower die placed on the lower base.

本発明は、平板状の下架台に下型を上下動可能に載置し、該下型の上昇時に前記下架台と下型との間にハケを挿入して抜きかすを排出するように形成したので、前記下架台にシュート穴を開口する必要がなくなり、下架台の機械的強度が増加する。従って、下型に多数のパンチ穴が存在しても、下架台の上面全体で下型を支持するため、下型に変形が生じることはない。   The present invention is configured such that a lower mold is placed on a flat plate-like base so as to be movable up and down, and a brush is inserted between the lower base and the lower mold when the lower mold is lifted to discharge the scraps. Therefore, it is not necessary to open a chute hole in the lower frame, and the mechanical strength of the lower frame increases. Therefore, even if there are a large number of punch holes in the lower mold, the lower mold is supported by the entire upper surface of the lower base, so that the lower mold is not deformed.

また、下型の厚みを薄く形成できるので、下型の重量が軽くなって段取り変えの際に下型の交換が容易になるとともに、下型の製作における材料費の軽減と加工工数の削減によりコストダウンに寄与できる。   In addition, since the lower mold can be made thinner, the weight of the lower mold becomes lighter, making it easier to replace the lower mold when changing the setup, and reducing the material costs and processing man-hours in lower mold production. It can contribute to cost reduction.

以下、本発明に係るプレス打ち抜き装置について、好適な実施例をあげて説明する。下型を支持する下架台にシュート穴を開口せずに機械的強度を向上させ、かつ、簡易な構成で抜きかすを排出できるようにするという目的を達成するために、本発明は平板状の下架台に前記下型を上下動可能に載置し、該下型の上昇時に前記下架台と下型との間にハケを挿入して抜きかすを排出するように形成したことにより実現した。   Hereinafter, the press punching apparatus according to the present invention will be described with reference to preferred embodiments. In order to achieve the object of improving mechanical strength without opening a chute hole in the undercarriage that supports the lower mold, and enabling the discharge of scraps with a simple configuration, the present invention provides a flat plate-like shape. This was realized by placing the lower mold on the lower pedestal so as to be movable up and down, and inserting a brush between the lower pedestal and the lower mold when the lower mold was lifted to discharge the scraps.

図1は本発明に係るプレス打ち抜き装置の全体構成図であり、説明の都合上、図6に示した従来技術と同一構成部分には同一符号を付すものとする。パンチ1を備えた上型2が上架台3に固定され、該上型2にはパンチ1が貫通する貫通穴を有したストリッパプレート4が取り付けられている。また、前記パンチ1が挿入するパンチ穴5を備えた下型6は平板状の下架台20に載置され、パンチ穴5の下部には大径の逃げ部5aが設けられている。前記パンチ1とパンチ穴5が正確に一致するように、上型3に設けたガイドピン8と下型6に設けたガイド穴9により位置合わせが行われた状態に設置され、該下型6は昇降機構21により上下動可能に形成されている。   FIG. 1 is an overall configuration diagram of a press punching apparatus according to the present invention. For convenience of explanation, the same components as those in the prior art shown in FIG. An upper die 2 provided with a punch 1 is fixed to an upper frame 3, and a stripper plate 4 having a through hole through which the punch 1 passes is attached to the upper die 2. The lower die 6 having the punch hole 5 into which the punch 1 is inserted is placed on a flat plate-shaped undercarriage 20, and a large-diameter relief portion 5 a is provided below the punch hole 5. In order for the punch 1 and the punch hole 5 to exactly coincide with each other, the guide pin 8 provided in the upper die 3 and the guide hole 9 provided in the lower die 6 are positioned so as to be aligned. Is formed to be movable up and down by an elevating mechanism 21.

被加工シート材10を打ち抜き加工する場合は、図2に示すように、被加工シート材10を前記上型2と下型6の間に挿入し、図示しない位置決め装置で被加工シート材10を下型6に位置決め載置する。上架台3と一体に上型2を下降させると、先ず、被加工シート材10がストリッパプレート4によって下型6の上面に押さえ付けられる。図3に示すように、上型2がさらに下降してパンチ1がストリッパプレート4の貫通穴を貫通し、上型2のパンチ1と下型6のパンチ穴5とのせん断により被加工シート材10が打ち抜かれる。   When the work sheet material 10 is punched, as shown in FIG. 2, the work sheet material 10 is inserted between the upper mold 2 and the lower mold 6 and the work sheet material 10 is inserted by a positioning device (not shown). Position and place on the lower mold 6. When the upper die 2 is lowered integrally with the upper platform 3, first, the processed sheet material 10 is pressed against the upper surface of the lower die 6 by the stripper plate 4. As shown in FIG. 3, the upper die 2 is further lowered so that the punch 1 passes through the through hole of the stripper plate 4, and the sheet material to be processed is sheared by the punch 1 of the upper die 2 and the punch hole 5 of the lower die 6. 10 is punched out.

パンチ1で打ち抜かれた抜きかす11は前記パンチ穴5に溜まり、打ち抜き加工の繰り返しによって順次パンチ穴5の下部に押し下げられ、図4に示すように、抜きかす11が逃げ部5aに至ったときに下方に落下し、下架台20の上面に抜きかす11が順次溜まる。図示例では被加工シート材10の一箇所を打ち抜いているが、実際には上型2と下型6には複数のパンチ1とパンチ穴5が設けられており、同時に多数の箇所を打ち抜き加工する。   When the scrap 11 punched by the punch 1 accumulates in the punch hole 5 and is sequentially pushed down to the lower portion of the punch hole 5 by repeating the punching process, as shown in FIG. 4, when the scrap 11 reaches the escape portion 5a. Then, the scraps 11 are sequentially accumulated on the upper surface of the undercarriage 20. In the example shown in the figure, one part of the sheet material to be processed 10 is punched, but actually, the upper die 2 and the lower die 6 are provided with a plurality of punches 1 and punch holes 5, and a number of points are punched at the same time. To do.

1回打ち抜いた後または数回打ち抜いた後に、上型2を上昇するとともに昇降機構21の作動により下型6を上昇させ、下架台20と下型6との間に空間部22を形成する。この空間部22にハケ23を挿入し、該ハケ23にて抜きかす11を排出する。抜きかす11を排出した後は、ハケ23を取り出して下型6を下降させ、図1に示す下型6を下架台に載置した状態に復帰して、再び打ち抜き作業に戻る。   After punching once or punching several times, the upper die 2 is raised and the lower die 6 is raised by the operation of the lifting mechanism 21 to form a space 22 between the lower base 20 and the lower die 6. A brush 23 is inserted into the space 22, and the scrap 11 is discharged by the brush 23. After discharging the punch 11, the brush 23 is taken out and the lower die 6 is lowered to return to the state where the lower die 6 shown in FIG. 1 is placed on the gantry, and the punching operation is resumed.

なお、前記ハケ23は、下型6が上昇したときに、図示しない駆動機構にて自動的に空間部22へ挿入されて、抜きかす11を排出するように形成されている。   The brush 23 is formed so as to be automatically inserted into the space 22 by a driving mechanism (not shown) and the scrap 11 is discharged when the lower mold 6 is raised.

而して、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。   Thus, the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
