Description

この発明は、複数の工具支持体を交換した使用するパンチプレスに関する。   The present invention relates to a punch press used by replacing a plurality of tool supports.

従来、複数の工具を交換使用可能としたパンチプレスとして、工具支持体をタレットとするタレット式のものが一般的である。しかし、タレットパンチプレスでは、タレット上に保持できるツールの種類，サイズが限られ、多彩な加工を行うことができない。そのため、工具支持体として次のようなカートリッジを用いるカートリッジ式のパンチプレスが提案されている（例えば特許文献１）。これは、複数のツールを搭載した矩形のカートリッジを複数準備し、これらカートリッジを直線経路のレール上でパンチ位置に出し入れすることにより、カートリッジ交換を行うものである。   Conventionally, as a punch press that allows a plurality of tools to be exchanged, a turret type having a tool support as a turret is generally used. However, in the turret punch press, the types and sizes of tools that can be held on the turret are limited, and various processes cannot be performed. Therefore, a cartridge type punch press using the following cartridge as a tool support has been proposed (for example, Patent Document 1). In this method, a plurality of rectangular cartridges on which a plurality of tools are mounted are prepared, and the cartridges are exchanged by putting these cartridges in and out of the punch position on the rail of the linear path.

しかし、上記カートリッジ式のパンチプレスは、カートリッジ内に並べられたツールの割り出しを、ラムを有するパンチ駆動部の平面移動により行うものであるため、移動する部分の重量が重くてツールの高速割り出しが難しい。カートリッジの直線移動で一方向のツール割り出しを行うものもあるが、これもカートリッジ全体の直線移動が必要なため、高速割り出しが難しい。   However, the cartridge type punch press performs indexing of the tools arranged in the cartridge by the plane movement of the punch driving unit having the ram, so that the moving part is heavy and high speed indexing of the tool is possible. difficult. Some tools perform one-way tool indexing by linear movement of the cartridge, but this also requires linear movement of the entire cartridge, making high-speed indexing difficult.

そこで、本出願人は、カートリッジとなる円形の工具支持体を用い、旋回動作する工具支持体交換装置によりプレスフレームに渡すものを提案した（例えば、特願２００３−２９６４９号）。工具支持体は複数個を工具支持体交換装置に保持しておき、希望の工具支持体をプレスフレームに渡す。プレスフレームに渡した工具支持体は、位置決めして固定する。工具支持体交換装置は、複数の切欠状部を有し、これら各切欠状部に工具支持体を嵌まり込み状態とし、開閉自在な爪部材を係合させて保持する。各爪部材は専用の駆動源で開閉動作させる。
特開２０００−３５１０２８号公報 Therefore, the present applicant has proposed a circular tool support that serves as a cartridge and that is handed over to a press frame by a tool support changer that rotates (for example, Japanese Patent Application No. 2003-29649). A plurality of tool supports are held in the tool support changer, and the desired tool support is transferred to the press frame. The tool support passed to the press frame is positioned and fixed. The tool support exchanging device has a plurality of notch-like portions, the tool support is fitted in each of the notch-like portions, and engages and holds an openable / closable claw member. Each claw member is opened and closed by a dedicated drive source.

Note that the claw portion 24a and the collar portion 24b of the claw member 24 may be formed integrally by cutting or the like, or may be formed as separate parts and fixed integrally with each other. .

このように、爪部材２４の爪部２４ａが工具支持体３，４の切欠き部３ｄ，４ｄに係合することで、工具支持体３，４の回り止めがなされ、また鍔部２４ｂが工具支持体３，４の上向き面の僅か上方に位置することで、工具支持体３，４の上下移動が阻止される。   In this way, the claw portion 24a of the claw member 24 is engaged with the notches 3d and 4d of the tool supports 3 and 4 so that the tool supports 3 and 4 are prevented from rotating, and the flange 24b is used as a tool. By being positioned slightly above the upward surfaces of the supports 3 and 4, the vertical movement of the tool supports 3 and 4 is prevented.

爪部材２４の開閉は、爪開閉用連動機構２５，２６（図６，図７）により行われる。この爪開閉用連動機構２５，２６は、工具支持体設置部６，７における上記昇降部材４０，４１（図２）の昇降動作を利用して、爪部材２４を閉状態から開状態とするものである。爪部材２４は、切欠状部１８における載置部１８ａの近傍で上記支軸２４ｅの回りに水平回動自在に支持され、その基端部に支軸２４ｅと同心のセクタギヤ部２４ｃ（図８参照）が設けられている。   The claw member 24 is opened and closed by the claw opening / closing interlock mechanisms 25 and 26 (FIGS. 6 and 7). The claw opening / closing interlocking mechanisms 25 and 26 use the lifting / lowering operation of the lifting / lowering members 40 and 41 (FIG. 2) in the tool support installing portions 6 and 7 to change the claw member 24 from the closed state to the open state. It is. The claw member 24 is supported so as to be horizontally rotatable around the support shaft 24e in the vicinity of the mounting portion 18a in the notch 18 and a sector gear portion 24c concentric with the support shaft 24e (see FIG. 8). ) Is provided.

図６，図７において、爪開閉用連動機構２５，２６は、爪部材２４を閉じ方向に付勢する水平動自在な爪部材閉じ部材２７と、工具支持体設置部６，７における昇降部材４０，４１に設けられて爪部材２４が開く方向に爪部材閉じ部材２７を移動させる操作部２８，２９と、操作部２８，２９の昇降動作を爪部材閉じ部材２７の水平動作に変換する水平変換機構３０，３１とで構成される。
爪部材閉じ部材２７は、一側部に前記爪部材２４のセクタギヤ部２４ｃが噛合するラック部３２ａを有し交換装置本体１６，１７にその径方向に進退材に設けられた進退ロッド３２と、この進退ロッド３２を交換装置本体１６，１７の外周側に突出するように付勢するばね部材３３とからなる。 6 and 7, the claw opening / closing interlock mechanisms 25 and 26 include a horizontally movable claw member closing member 27 that urges the claw member 24 in the closing direction, and an elevating member 40 in the tool support installation portions 6 and 7. , 41 for moving the claw member closing member 27 in a direction in which the claw member 24 opens, and horizontal conversion for converting the lifting / lowering operation of the operation units 28, 29 into the horizontal movement of the claw member closing member 27 The mechanism 30 and 31 are comprised.
The claw member closing member 27 has a rack portion 32a with which the sector gear portion 24c of the claw member 24 meshes with one side portion, and an advance / retreat rod 32 provided on the advance / retreat material in the radial direction of the exchange device main body 16, 17. It comprises a spring member 33 that urges the advance / retreat rod 32 so as to protrude toward the outer peripheral side of the exchange device main bodies 16 and 17.

図６のように、上側の工具支持体交換装置８における水平変換機構３０は、進退ロッド３２の進退方向と平行な垂直面内で支軸３４ａ回りに揺動自在となるように、交換装置本体１６の外周部に略逆Ｌ字状のレバー３４を支持して構成される。このレバー３４の一端が、昇降部材４０に設けられた操作部２８で昇降部材４０の下降時に押されて揺動することにより、その他端で爪部材閉じ部材２７が爪部材２４を開く方向に移動させられる。操作部２８は、図１０に示すように昇降部材４０の下端に設けられている。
図７のように、下側の工具支持体交換装置９における水平変換機構３１は、進退ロッド３２の進退方向と平行な垂直面内で支軸３５ａ回りに揺動自在となるように、交換装置本体１７の外周部にバー状のレバー３５を支持して構成される。このレバー３５の下端が、昇降部材４１に設けられた操作部２９で昇降部材４１の上昇時に押されて揺動することにより、その上端で爪部材閉じ部材２７が爪部材２４を開く方向に移動させられる。操作部２９は、図１１に示すように昇降部材４１に支持された回転部材４３の上端に設けられている。 As shown in FIG. 6, the horizontal conversion mechanism 30 in the upper tool support exchanging device 8 is capable of swinging around the support shaft 34 a in a vertical plane parallel to the advancing and retreating direction of the advancing and retracting rod 32. 16 is configured by supporting a substantially inverted L-shaped lever 34 on the outer peripheral portion. One end of the lever 34 is pushed and swung by the operation unit 28 provided on the elevating member 40 when the elevating member 40 is lowered, so that the claw member closing member 27 moves in the direction to open the claw member 24 at the other end. Be made. The operation unit 28 is provided at the lower end of the elevating member 40 as shown in FIG.
As shown in FIG. 7, the horizontal conversion mechanism 31 in the lower tool support exchanging device 9 can be swung around the support shaft 35 a in a vertical plane parallel to the advance and retreat direction of the advance and retreat rod 32. A bar-shaped lever 35 is supported on the outer periphery of the main body 17. When the lower end of the lever 35 is pushed and swung by the operation unit 29 provided on the elevating member 41 when the elevating member 41 is raised, the claw member closing member 27 moves in the direction in which the claw member 24 opens at the upper end. Be made. The operation unit 29 is provided at the upper end of the rotating member 43 supported by the elevating member 41 as shown in FIG.

上記構成の動作を説明する。図５（Ａ）に上下の工具支持体交換装置８，９の交換装置本体１６，１７を示すように、これら交換装置本体１６，１７の円周方向複数箇所に設けられた各切欠状部１８には、種々の工具１，２を支持した工具支持体３，４が保持され、閉状態の爪部材２４で抜け止めされている。すなわち図１０，図１１のように、切欠状部１８に搭載されている工具支持体３，４の円周方向２箇所に設けられた切欠き部３ｄ，４ｄに爪部材２４の爪部２４ａが進入して、工具支持体３，４が回転不能に支持されると共に、爪部材２４の鍔部２４ｂが工具支持体３，４の所定の上向き面の上方に位置して、工具支持体３，４の上下動が規制される。鍔部２４ｂは、具体的には、パンチ工具支持体３に対しては横溝部３ｅ（図４）内に進入し、ダイ工具支持体４に対してはその上面に位置する。   The operation of the above configuration will be described. As shown in FIG. 5 (A), the changer bodies 16 and 17 of the upper and lower tool support changers 8 and 9, the notch portions 18 provided at a plurality of locations in the circumferential direction of the changer bodies 16 and 17. The tool supports 3 and 4 that support the various tools 1 and 2 are held by the claw member 24 in the closed state. That is, as shown in FIGS. 10 and 11, the claw portions 24 a of the claw member 24 are formed in the notches 3 d and 4 d provided at two places in the circumferential direction of the tool supports 3 and 4 mounted on the notch 18. The tool supports 3 and 4 are non-rotatably supported, and the hook 24b of the claw member 24 is positioned above a predetermined upward surface of the tool supports 3 and 4, The vertical movement of 4 is restricted. Specifically, the flange 24b enters the lateral groove 3e (FIG. 4) with respect to the punch tool support 3 and is positioned on the upper surface with respect to the die tool support 4.

希望の工具支持体３，４を使用するには、交換装置本体１６，１７を旋回させてその切欠状部１８をプレス位置Ｐに位置させる。このとき、図２のパンチ側の工具支持体設置部６の昇降部材４０は、回転部材４２と共に上方に、またダイ側の工具支持体設置部７の昇降部材４１は回転部材４３と共に下方に退避していて、工具支持体３，４がプレス位置Ｐに旋回移動することの妨げとなることが防止される。   In order to use the desired tool supports 3 and 4, the changer main bodies 16 and 17 are turned to place the notch 18 in the press position P. At this time, the lifting member 40 of the punch-side tool support installation portion 6 in FIG. 2 is retracted upward together with the rotating member 42, and the lifting member 41 of the die-side tool support installation portion 7 is retracted downward together with the rotating member 43. Thus, the tool supports 3 and 4 are prevented from obstructing the pivot movement to the press position P.

希望の工具支持体３，４を保持した切欠状部１８（図５）がプレス位置Ｐに来ると、上側の昇降部材４０の下降、および下側の昇降部材４１の上昇が、昇降機構２２，２３により行われる。昇降部材４０，４１の昇降に伴って、上側の回転部材４２が下降し、下側の回転部材４３が上昇する。これにより、図１０，図１１のように、回転部材４２，４３のカップリング部４２ａ，４３ａと工具支持体３，４のカップリング部３ｂ，４ｂとの噛み合いが行われる。このカップリング歯の噛み合い状態で、上下の引込結合手段３６，３７が工具支持体３，４の被係合部３ｃ，４ｃに係合して引き込み移動し、工具支持体３，４を上下の工具支持体設置部６，７の回転部材４２，４３に固定する。このときに、円周方向にカップリング歯が並ぶカップリング部４２ａ，４３ａとカップリング部３ｂ，４ｂとが噛み合うため、工具支持体３，４が精度良く位置決めされる。   When the notch 18 (FIG. 5) holding the desired tool supports 3 and 4 comes to the press position P, the upper elevating member 40 is lowered and the lower elevating member 41 is raised. 23. As the elevating members 40 and 41 are raised and lowered, the upper rotating member 42 is lowered and the lower rotating member 43 is raised. As a result, as shown in FIGS. 10 and 11, the coupling portions 42a and 43a of the rotating members 42 and 43 and the coupling portions 3b and 4b of the tool supports 3 and 4 are engaged. In this meshing state of the coupling teeth, the upper and lower retracting coupling means 36, 37 are engaged and engaged with the engaged portions 3c, 4c of the tool supports 3, 4 to move the tool supports 3, 4 up and down. It is fixed to the rotating members 42 and 43 of the tool support installation parts 6 and 7. At this time, since the coupling parts 42a and 43a and the coupling parts 3b and 4b are arranged in the circumferential direction, the tool supports 3 and 4 are accurately positioned.

上記結合動作における上下の昇降部材４０，４１の昇降動作に伴い、上下の交換装置本体１６，１７における切欠状部１８（図６（Ｂ））の爪部材２４が工具支持体３，４に対して係合解除される。
すなわち、図１０のようにパンチ側の昇降部材４０が下降すると、その下端の操作部２８が、図６（Ｂ）のように水平変換機構３０を構成するレバー３４に作用して、このレバー３４を回動させる。これにより爪開閉用連動機構２５の爪部材閉じ部材２７が、ばね部材３３の復元力に抗して交換装置本体１６の径方向内側に押し戻され、爪部材閉じ部材２７のラック部３２ａにセクタギヤ部２４ｃが噛合する爪部材２４が開き姿勢（係合解除姿勢）に回動して、爪部材２４の爪部２４ａがパンチ工具支持体３の切欠き部３ｄから係合解除される。爪部材２４の爪部２４ａは鍔部２４ｂよりも工具支持体３の径方向の中心側へ突出するものとされているので、爪部２４ａの係合解除と共に、鍔部２４ｂも工具支持体３の横溝部３ｅから外径側に確実に退避する。
ダイ側の工具支持体４に対しても、図１１のように昇降部材４１の上昇により、その上端の操作部２９が図７のように水平変換機構３１を構成するレバー３５に作用して、このレバー３５を回動させる。これにより交換装置本体１７の爪開閉用連動機構２６が同様に動作して、爪部材２４の爪部２４ａがダイ工具支持体４の切欠き部４ｄから係合解除される。爪部材２４の鍔部２４ｂも工具支持体４の上面から外径側に確実に退避する。 As the upper and lower elevating members 40 and 41 are moved up and down in the coupling operation, the claw members 24 of the notched portions 18 (FIG. 6B) in the upper and lower exchange device main bodies 16 and 17 are moved against the tool supports 3 and 4. Is disengaged.
That is, when the punch-side lifting member 40 is lowered as shown in FIG. 10, the operation portion 28 at its lower end acts on the lever 34 constituting the horizontal conversion mechanism 30 as shown in FIG. Rotate. As a result, the claw member closing member 27 of the claw opening / closing interlock mechanism 25 is pushed back inward in the radial direction of the exchange device main body 16 against the restoring force of the spring member 33, and the sector gear portion is placed on the rack portion 32 a of the claw member closing member 27. The claw member 24 engaged with the claw 24 is rotated to the open posture (disengagement posture), and the claw portion 24 a of the claw member 24 is disengaged from the notch portion 3 d of the punch tool support 3. Since the claw portion 24a of the claw member 24 protrudes toward the radial center of the tool support 3 from the flange portion 24b, the hook portion 24b is also disengaged from the tool support 3 along with the disengagement of the claw portion 24a. It is surely retracted from the lateral groove 3e to the outer diameter side.
Also with respect to the tool support 4 on the die side, as the elevating member 41 ascends as shown in FIG. 11, the operation portion 29 at the upper end acts on the lever 35 constituting the horizontal conversion mechanism 31 as shown in FIG. The lever 35 is rotated. As a result, the claw opening / closing interlock mechanism 26 of the exchange device main body 17 operates in the same manner, and the claw portion 24 a of the claw member 24 is disengaged from the notch portion 4 d of the die tool support 4. The flange 24b of the claw member 24 is also securely retracted from the upper surface of the tool support 4 to the outer diameter side.

このように工具支持体３，４の割り出しが完了した後、工具支持体３，４における希望の工具１，２を割出し、パンチ加工を行う。   After the indexing of the tool supports 3 and 4 is completed in this way, the desired tools 1 and 2 on the tool supports 3 and 4 are indexed and punched.

この構成のパンチプレスによると、爪開閉用連動機構２５，２６を設け、プレスフレーム５における昇降部材４０，４１の昇降動作を利用して爪部材２４を閉状態から開状態とするため、爪部材２４を開くための専用の駆動源が不要であり、したがってその駆動源の動作タイミングの制御手段も不要となり、構成が簡易化でき、低コスト化が図れる。また爪部材２４の開閉方向を水平方向としたため、閉じ力によって工具支持体３，４の荷重を支持する必要がなく、軽い開閉力で工具支持体３，４を確実に支持することができる。
また、爪開閉用連動機構２５，２６は、爪部材２４を閉じ方向に付勢する水平動自在な爪部材閉じ部材２７と、前記昇降部材４０，４１に設けられて爪部材２４が開く方向に爪部材閉じ部材２７を移動させる操作部２８，２９とを有するものとしたため、常時は爪部材２４が閉じ状態となり、駆動源を必要とせずに、工具支持体３，４の保持が行える。さらに、昇降部材４０，４１に設けられた操作部２８，２９によって、爪部材２４が開く方向に爪部材閉じ部材２７を移動させるようにしたため、簡単な構成で確実に爪部材閉じ部材２７を移動させることができる。 According to the punch press having this configuration, the claw opening / closing interlocking mechanisms 25 and 26 are provided, and the claw member 24 is moved from the closed state to the open state by using the lifting and lowering operations of the lifting members 40 and 41 in the press frame 5. A dedicated drive source for opening the opening 24 is not required, and therefore a means for controlling the operation timing of the drive source is not required, the configuration can be simplified, and the cost can be reduced. Further, since the opening / closing direction of the claw member 24 is the horizontal direction, it is not necessary to support the load of the tool supports 3 and 4 with the closing force, and the tool supports 3 and 4 can be reliably supported with a light opening and closing force.
Further, the claw opening / closing interlocking mechanisms 25 and 26 are provided in the horizontally movable claw member closing member 27 for urging the claw member 24 in the closing direction and the elevating members 40 and 41 so as to open the claw member 24. Since the operation portions 28 and 29 for moving the claw member closing member 27 are provided, the claw member 24 is always in a closed state, and the tool supports 3 and 4 can be held without requiring a drive source. Further, since the claw member closing member 27 is moved in the opening direction of the claw member 24 by the operation portions 28 and 29 provided on the elevating members 40 and 41, the claw member closing member 27 is reliably moved with a simple configuration. Can be made.

さらに、操作部２８，２９の昇降動作を水平動作に変換する水平変換機構３０，３１を設け、この水平変換機構３０，３１による水平動作によって、爪部材閉じ部材２７が爪部材２７を開く方向に移動させるものとしたため、昇降部材４０，４１の昇降動作を、より簡単に爪部材閉じ部材２７の水平動作とできる。そのため、昇降部材４０，４１の昇降動作から、爪部材２７を開き動作させる機構が、より簡単な構成とできる。
また、上下の工具支持体交換装置８，９は、昇降部材４０，４１に連動して爪部材２４を開閉させるため、昇降部材４０，４１の上下移動の監視により、爪部材２４の開閉動作の確認を省略できる。特に、下側の工具支持体交換装置９は、昇降部材４１の昇降にリンク機構６３を用いるため、上下移動のみを監視すれば、位置決め部材２４の開閉動作の確認を取る必要がない。 Further, horizontal conversion mechanisms 30 and 31 for converting the raising and lowering operations of the operation units 28 and 29 to horizontal operations are provided, and the claw member closing member 27 opens the claw member 27 in a direction by the horizontal operation by the horizontal conversion mechanisms 30 and 31. Since it is made to move, the raising / lowering operation | movement of the raising / lowering members 40 and 41 can be made into the horizontal operation | movement of the nail | claw member closing member 27 more easily. Therefore, a mechanism for opening the claw member 27 from the lifting / lowering operation of the lifting / lowering members 40 and 41 can be simplified.
Further, since the upper and lower tool support changers 8 and 9 open and close the claw member 24 in conjunction with the lifting members 40 and 41, the opening and closing operation of the claw member 24 is monitored by monitoring the vertical movement of the lifting members 40 and 41. Confirmation can be omitted. In particular, since the lower tool support exchanging device 9 uses the link mechanism 63 for raising and lowering the elevating member 41, it is not necessary to confirm the opening / closing operation of the positioning member 24 if only the vertical movement is monitored.
