Description

本考案はパンチと共に圧造ステーションを構成するダイに対して素材を搬出入する素材移送用チャック装置に関する。    The present invention relates to a material transfer chuck device that carries material in and out of a die that forms a forging station together with a punch.

従来、ボルトやナット、或いはその他の各種パーツ部品を成形する圧造成形機は、機台の側部より供給された素材を、相対向するダイとパンチとを備えた圧造ステーションで粗から精に段階的に圧造加工することにより所定形状の製品を連続的に製造するものであるが、この種の成形機には、上記の素材を掴んで圧造ステーション間にわたって横方向に移送する素材移送用チャック装置が設けられている。つまり、素材移送用チャックは前段と後段との圧造ステーション間にわたって往復移動され、前段の圧造ステーションにおいて加工された素材を掴んで後段の圧造ステーションに移送する。  Conventionally, forging machines that mold bolts, nuts, and other various parts are processed from rough to fine in a forging station equipped with opposing dies and punches. In this type of molding machine, a material transfer chuck device that grips the above material and transfers it horizontally between the forging stations. Is provided. That is, the material transfer chuck is reciprocated between the front and rear pressing stations, and grips the processed material at the front pressing station and transfers it to the subsequent pressing station.

そして、従来の素材移送用チャック装置としては、例えば図7に示すように、チャック本体40と、チャック本体40の左右位置に回転自在に設けられた左右一対のチャックアーム取付軸41,41と、これら取付軸41,41にそれぞれ取付けられ先端にチャック爪42を有するチャックアーム43,43と、チャック本体40内に摺動自由挿嵌され、パンチの作動に連動して昇降される昇降ロッド44と、チャックアーム取付軸41,41にそれぞれ固定された従動ギヤ45,45とからなり、昇降ロッド43を従動ギヤ45,45間に通し、昇降ロッド44に形成されたラック44aをそれぞれ従動ギヤ45,45に噛み合わせ、昇降ロッド44を昇降させることによって上記チャックアーム取付軸41,41を回転させ、これによりチャックアーム43,43を介してチャック爪42,42を図7に示した実線位置と二点鎖位置とにわたって開閉させ、素材の掴持及び解除ができるように構成されている。

Japanese Utility Model Publication No. 05-28535

ところが、上記したチャック装置によれば、チャック爪42,42がチャックアーム取付軸41,41を支点として回転させ横方向に開くだけであるため、例えば図8に示すように短軸パーツなどで、ダイ46の径Dとほぼ同径の太径パンチ47を用いる場合、チャック爪42,42を、太径パンチ47をかわして横移動させることはできないものであった。つまり、図7の一点鎖線で示すパンチ径D1以下でないと横移動させることはできないものであった。そのため、パンチ47が後退するのを待ち、その後退状態でチャック爪42,42(チャック装置)を前段側に横移動させることになる。その結果、例えば図8に示すようにパンチ47の後退後、チャック爪42,42が前段側に移動する間にダイ46側のノックアウトピン48により押し出される複雑な形状の短軸成形素材Xをノックアウトピン48と共に挟み付けてダイ46の前方で保持する短軸パーツの補助保持装置49を特別に設ける必要があり、構造が複雑となるばかりか作業性も悪い問題を有していた。  However, according to the above-described chuck device, the chuck claws 42, 42 are merely rotated laterally with the chuck arm mounting shafts 41, 41 as fulcrums, so that, for example, as shown in FIG. In the case of using a large diameter punch 47 having substantially the same diameter as the diameter D of the die 46, the chuck claws 42, 42 cannot be moved laterally by passing the large diameter punch 47. That is, the lateral movement cannot be performed unless the punch diameter D1 is equal to or smaller than the one-dot chain line in FIG. Therefore, it waits for the punch 47 to move backward, and in the retracted state, the chuck claws 42 and 42 (chuck device) are moved laterally to the front side. As a result, for example, as shown in FIG. 8, after the punch 47 is retracted, the short shaft molding material X having a complicated shape that is pushed out by the knockout pin 48 on the die 46 side while the chuck claws 42 and 42 are moved to the front stage side is knocked out. It is necessary to specially provide an auxiliary holding device 49 for short shaft parts that is sandwiched together with the pins 48 and held in front of the die 46, which has a problem in that the structure is complicated and the workability is also poor.

そこで、本考案は、チャック爪部の開放時、チャック爪部を横に開くと同時にチャック爪部をもつレバー全体をダイ上方に大きく退避移動させることのできる素材移送用チャック装置の提供を課題とする。  Therefore, the present invention has an object to provide a chuck device for material transfer that can open the chuck claw part sideways when the chuck claw part is opened, and at the same time, can move the entire lever having the chuck claw part up and down largely above the die. To do.

上記した課題を解決するために、本願の請求項1に記載の考案は、パンチと共に圧造ステーションを構成するダイに対して素材を搬出入する素材移送用チャックであって、上下に延びるガイド部を有するチャック本体と、ガイド部に沿って上下動可能で、左右一対のレバー取付軸を有する移動体と、移動体をパンチの作動に同期して昇降させる昇降機構と、チャック本体のガイド部下方に中心軸を介してそれぞれ揺動自由に設けられる左右一対の揺動アームと、上端部が左右一対の各レバー取付軸にまた中間部が左右一対の揺動アームの各遊端部に枢支され、下端部にチャツク爪部を備えた左右一対のレバーとを備え、移動体の下降により各レバー全体を下方に移動させながら左右一対の揺動アームの各遊端部を下方に揺動させて互いに近接させ、各レバーのチャツク爪部を閉じる方向に揺動させて素材を掴持させる一方、移動体の上昇により左右一対の揺動アームの各遊端部を上方に揺動させて互いに離反させ、各レバーのチャツク爪部を開放させると共に各レバー全体を上方に移動させるように構成したことを特徴とする。  In order to solve the above-described problem, the invention described in claim 1 of the present application is a material transfer chuck for transferring material to and from a die that constitutes a forging station together with a punch, and includes a guide portion extending vertically. A chuck body, a movable body that can move up and down along the guide portion, and has a pair of left and right lever mounting shafts, an elevating mechanism that moves the movable body up and down in synchronization with the operation of the punch, and a lower guide portion of the chuck body A pair of left and right oscillating arms that are freely oscillated through a central shaft, an upper end portion is pivotally supported by a pair of left and right lever mounting shafts, and an intermediate portion is pivotally supported by each free end portion of the pair of left and right oscillating arms. And a pair of left and right levers having chuck claws at the lower end, and swinging each free end of the pair of left and right swing arms downward while moving the entire lever downward by lowering the moving body. Close to each other And swinging the chuck claw portion of each lever in the closing direction to grip the material, while the movable body is lifted, the free end portions of the pair of left and right swing arms are swung upward to be separated from each other, The chuck claw portion of each lever is opened and the entire lever is moved upward.

本考案によれば、昇降機構による移動体の下降により、各レバー全体を下方に移動させながら左右一対の揺動アームの各遊端部を下方に揺動させて互いに近接させ、各レバーのチャツク爪部を閉じる方向に揺動させて素材を掴持させることができる。一方、昇降機構による移動体の上昇により左右一対の揺動アームの各遊端部を上方に揺動させて互いに離反させ、各レバーのチャツク爪部を開放させると共に各レバー全体を上方に移動させることができる。これにより、各レバーのチャック爪部をダイ径と同じ位置よりもさらに上方に移動させることが可能となる。その結果、ダイ径と同じ径の太径パンチであってもパンチの後退を待たずに太径パンチをかわしてチャック装置を直ちに前段の圧造ステーションに横移動させ、その移動位置で待機させることができる。したがって、パンチ側のノックアウトピンとダイ側のノックアウトピンとで短軸成形素材を挟み付けて支持ながらダイの前方に押し出し、その成形素材を待機するチャック爪部で掴むことが可能となる。  According to the present invention, when the moving body is lowered by the elevating mechanism, the free end portions of the pair of left and right swing arms are swung downward and moved closer to each other while moving all the levers downward. The material can be gripped by swinging the claw portion in the closing direction. On the other hand, the free end portions of the pair of left and right swing arms are swung upward by moving the moving body by the lifting mechanism so as to be separated from each other, thereby opening the chuck claws of each lever and moving the entire lever upward. be able to. As a result, the chuck claw portion of each lever can be moved further upward than the same position as the die diameter. As a result, even if it is a large diameter punch having the same diameter as the die diameter, the chuck device can be moved laterally to the forging station in the previous stage without waiting for the retraction of the punch and waited at the moving position. it can. Accordingly, it is possible to hold the short shaft molding material between the punch-side knockout pin and the die-side knockout pin while pushing and supporting the short-axis molding material, and to hold the molding material with the chucking claw portion waiting.

以下、本考案の実施の形態を図面に基づいて説明する。
図1は、多段式圧造成形機を示し、該成形機1の機台1aの所定位置にダイブロック2が設けられ、ダイブロック2に複数個のダイ3〜3が一定の間隔配置されると共に、これらのダイ3〜3に向って身体するラム(図示せず)の前面に、上記ダイ3〜3と同数のパンチ(図示せず)がこれらのダイ3〜3に対抗して配置され、これらの各ダイ3〜3とパンチとにより複数の圧造ステーションが構成され、かつパンチの進退移動によって、パンチとダイ3〜3との間で素材を粗から精に順次段階的に圧造加工するようになされている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a multi-stage forging machine, in which a die block 2 is provided at a predetermined position of a machine base 1a of the molding machine 1, and a plurality of dies 3 to 3 are arranged on the die block 2 at a constant interval. The same number of punches (not shown) as the above-mentioned dies 3 to 3 are arranged on the front surface of the ram (not shown) which faces the dies 3 to 3, A plurality of forging stations are constituted by each of these dies 3 to 3 and the punch, and the material is gradually and gradually forcibly processed between the punch and the dies 3 to 3 by the forward and backward movement of the punch. Has been made.

また、上記ダイブロック2の上には支持フレームが摺動可能に取付けられる。この支持フレーム4の一端には、パンチの進退動作に同期してパンチの進退方向と直交するダイ並設方向に所定のストロークで進退する駆動ロッド5が連結ピン6によって連結され、この駆動ロッド5の進退動作に伴って支持フレーム4が隣接するダイ3,3の間隔に等しい距離だけ一往復移動するように構成されている。  A support frame is slidably mounted on the die block 2. One end of the support frame 4 is connected by a connecting pin 6 to a drive rod 5 that advances and retreats with a predetermined stroke in a die juxtaposition direction orthogonal to the advance and retreat direction of the punch in synchronization with the advance and retreat operation of the punch. The support frame 4 is configured to reciprocate by a distance equal to the interval between the adjacent dies 3 and 3 in accordance with the forward and backward movement.

上記支持フレーム4の前面部には、ダイ3〜3と同数の素材移送用チャック装置10〜10が配設され、上記駆動ロッド5による支持フレーム4の往復移動に伴い各チャック装置10〜10が素材Xを掴持してダイ間にわたって順次移送させるようになされている。  On the front surface of the support frame 4, the same number of material transfer chuck devices 10 to 10 as the dies 3 to 3 are disposed. As the support frame 4 is reciprocated by the drive rod 5, the chuck devices 10 to 10 are connected. The material X is gripped and sequentially transferred between dies.

そして、素材移送用チャック装置10は、以下に述べるカセット構造とされてボルト(図示せず)などにより支持フレーム4に着脱可能に取付けられる。  The material transfer chuck device 10 has a cassette structure described below and is detachably attached to the support frame 4 with bolts (not shown).

具体的には、素材移送用チャック装置10は、図2ないし図5に示すように、チャック本体11と、チャック本体11に上下に設けられるガイドレール12と、ガイドレール12に沿って上下動可能で、左右一対のレバー取付軸13,13を有する移動体14と、移動体14をパンチの作動に同期して昇降させる昇降機構15と、チャック本体11のガイドレール12下部に中心軸16を介してそれぞれ揺動自由に設けられる左右一対の揺動アーム17,17と、上端部が左右一対の各レバー取付軸13,13にまた中間部が左右一対の揺動アーム17,17の各遊端部に枢支軸18,18を介して枢支され、下端部にチャック爪部19aを有する左右一対のレバー19,19を備え、移動体14の下降により各レバー19,19を下方に移動させると共に左右一対の揺動アーム17,17の遊端部を下方に揺動させて互いに近接させ、各レバー19,19のチャック爪部19a,19aを閉じる方向に揺動させる一方、移動体14の上昇により左右一対の揺動アーム17,17の各遊端部を上方に揺動させて互いに離反させ、各レバー19,19のチャック爪部19a,19aを開放させながら各レバー19,19を上方に移動させるように構成している。  Specifically, as shown in FIGS. 2 to 5, the material transfer chuck device 10 can move up and down along the chuck body 11, the guide rail 12 provided on the chuck body 11 in the vertical direction, and the guide rail 12. Thus, a movable body 14 having a pair of left and right lever mounting shafts 13, an elevating mechanism 15 that raises and lowers the movable body 14 in synchronization with the operation of the punch, and a central shaft 16 below the guide rail 12 of the chuck body 11. And a pair of left and right swing arms 17, 17 provided freely swingable, a pair of left and right lever mounting shafts 13, 13 at the upper end and a free end of the pair of left and right swing arms 17, 17 at the middle. It is provided with a pair of left and right levers 19, 19 that are pivotally supported by the support shafts 18, 18 and that have a chuck claw portion 19 a at the lower end, and the levers 19, 19 are moved downward by lowering the moving body 14. At the same time, the free end portions of the pair of left and right swing arms 17 and 17 are swung downward to be close to each other, and the chuck claws 19a and 19a of the levers 19 and 19 are swung in the closing direction. , The free end portions of the pair of left and right swing arms 17 and 17 are swung upward to move away from each other, and the chuck claws 19a and 19a of the levers 19 and 19 are opened while the levers 19 and 19 are opened. It is configured to move upward.

昇降機構15は、ガイドレール12の上部に設けられるサーボモーター21と、サーボモーター21に連動連結されかつ移動体14に設けられたボールねじナット14aに螺合するボールねじ22とを備え、サーボモーター21によるボールねじ22の制御回転によりパンチの作動に同期して移動体14を昇降させるようになされている。なお、図中、符号23は、ガイドレール12と、ボールねじ22と、移動体14のボールねじナット14aをもつガイド部分を覆うケースである。  The elevating mechanism 15 includes a servo motor 21 provided on the upper portion of the guide rail 12, and a ball screw 22 that is linked to the servo motor 21 and screwed to a ball screw nut 14 a provided on the moving body 14. The moving body 14 is moved up and down in synchronization with the operation of the punch by the controlled rotation of the ball screw 22 by 21. In the figure, reference numeral 23 denotes a case that covers the guide portion having the guide rail 12, the ball screw 22, and the ball screw nut 14 a of the moving body 14.

次に以上のように構成する素材移送用チャック装置10の作用について説明する。  Next, the operation of the material transfer chuck device 10 configured as described above will be described.

素材移送用チャック装置10の開閉は、パンチの作動に同期して作動するサーボモータ21におけるボールねじ22の正回転により、図5に示す最上方位置の状態から移動体14が下降する。これにより、図4に示す中間位置では左右一対の揺動アーム17,17が水平状態となるように揺動して両レバー19,19が一旦ほぼ平行状態となる。その後さらに移動体14が下降することにより、左右一対の揺動アーム17,17の遊端部が下方に揺動して互いに近接し、各レバー19,19全体を下方に移動させながらその爪部19a,19aを閉じる方向に揺動させ、図2に示すように素材Xを掴持することになる。また、その掴持タイミングでサーボモーター21の作動が停止される。  As for the opening and closing of the chuck 10 for material transfer, the movable body 14 is lowered from the uppermost position shown in FIG. 5 by the normal rotation of the ball screw 22 in the servo motor 21 that operates in synchronization with the operation of the punch. As a result, at the intermediate position shown in FIG. 4, the pair of left and right swing arms 17 and 17 are swung so as to be in a horizontal state, and both levers 19 and 19 are once brought into a substantially parallel state. Thereafter, when the moving body 14 is further lowered, the free end portions of the pair of left and right swing arms 17 and 17 swing downward and come close to each other, and move the entire levers 19 and 19 downward while moving the claw portions thereof. 19a and 19a are swung in the closing direction, and the material X is gripped as shown in FIG. Further, the operation of the servo motor 21 is stopped at the holding timing.

一方、パンチの打ち込み時には、パンチの打ち込み開始直後の所定のタイミングでサーボモーター21が作動してボールねじ22を逆回転させることにより、図2に示す掴持位置の状態から移動体14が上昇する。これにより、パンチが素材Xをダイ3内に打ち込む一方、移動体14の上昇により左右一対の揺動アーム17,17の各遊端部を上方に揺動させて互いに離反させ、各レバー19,19の爪部19a,19aを開放させながら両レバー19,19全体を上方に移動させる。そして、図4に示す中間位置では左右一対の揺動アーム17,17がその遊端部が水平状態となるように揺動して両レバー19,19が一旦ほぼ平行状態となる。その後さらに移動体14が上昇することにより、移動体14の上昇により左右一対の揺動アーム17,17の各遊端部を上方へさらに揺動させて各レバー19,19の爪部19a,19aをやや近接させることになるが、各レバー19,19の爪部19a,19aをダイ3の径と同じ位置よりもさらに上方に移動させることができる。これにより、ダイ3の径Dと同じ径の太径パンチであってもパンチの後退を待たずに太径パンチをかわしてチャック装置10を直ちに前段の圧造ステーションに横移動させ、その移動位置で待機させることができる。  On the other hand, when the punch is driven, the servomotor 21 is operated at a predetermined timing immediately after the start of punching and the ball screw 22 is rotated in the reverse direction, whereby the movable body 14 is lifted from the gripping position shown in FIG. . As a result, the punch drives the material X into the die 3, while the movable body 14 moves upward to swing the free end portions of the pair of left and right swing arms 17, 17 apart from each other. The levers 19 and 19 are moved upward while the 19 claw portions 19a and 19a are opened. Then, at the intermediate position shown in FIG. 4, the pair of left and right swing arms 17 and 17 swings so that their free ends are in a horizontal state, and both levers 19 and 19 once become substantially parallel. Thereafter, when the movable body 14 is further raised, the free end portions of the pair of left and right swing arms 17 and 17 are further swung upward by the lift of the movable body 14, and the claw portions 19 a and 19 a of the levers 19 and 19 are moved. However, the claws 19a and 19a of the levers 19 and 19 can be moved further upward than the same position as the diameter of the die 3. As a result, even if it is a large diameter punch having the same diameter as the diameter D of the die 3, the chuck device 10 is immediately moved laterally to the forging station in the preceding stage without waiting for the punch to retreat, and at the moving position. Can wait.

したがって、例えば図6に示すようにパンチ24側のノックアウトピン25とダイ3側のノックアウトピン3aとで例えば短軸成形素材Xを挟み付けて支持ながらダイ3の前方に押し出し、その短軸成形素材Xを待機するチャック装置10のレバー19,19の上記した掴持動作で掴むことができる。つまり、従来ではパンチの後退を待ってその後退後にチャック装置10を前段の圧造ステーションに横移動させる一方、図9に示す従来例のようにダイ46側のノックアウトピン48により押し出される短軸成形素材Xをそのノックアウトピン48と共に挟み付けて支持しながらダイ46の前方に押し出す複雑な短軸補助システム49が特別に設ける必要があったがこれを不要にできる。なお、図6中、符号26はブレーキである。  Therefore, for example, as shown in FIG. 6, the short shaft molding material 25 is pushed forward of the die 3 while being supported by sandwiching the short shaft molding material X between the knockout pin 25 on the punch 24 side and the knockout pin 3 a on the die 3 side. The levers 19 and 19 of the chuck device 10 waiting for X can be gripped by the gripping operation described above. That is, conventionally, after waiting for the punch to retreat, the chuck device 10 is moved laterally to the forging station in the previous stage, and the short shaft forming material pushed out by the knockout pin 48 on the die 46 side as in the conventional example shown in FIG. A complicated short-axis auxiliary system 49 that pushes X in front of the die 46 while sandwiching and supporting the X together with the knockout pin 48 needs to be specially provided. In FIG. 6, reference numeral 26 denotes a brake.

上記した実施の形態ではレバー19の先端部にチャック爪部19aを一体に形成しているので、チャック爪部19aの調整が簡単にできる。また、枢支軸18,18に偏心軸を用いればこの偏心軸の固定角度を適宜変更することにより、チャック爪部19aの素材Xに対する掴持タイミングの調整が簡単容易に行うことができる。なお、レバー19に別体のチャック爪を着脱可能に取付けるようにしてもよいことは勿論である。  In the above-described embodiment, since the chuck claw portion 19a is integrally formed at the tip end portion of the lever 19, the chuck claw portion 19a can be easily adjusted. Further, if an eccentric shaft is used for the pivot shafts 18, 18, the holding timing of the chuck claw portion 19a with respect to the material X can be easily and easily adjusted by appropriately changing the fixed angle of the eccentric shaft. Of course, a separate chuck claw may be detachably attached to the lever 19.

また、上記した実施の形態では昇降機構15として、サーボモータ21とボールねじ22を用いたけれども、かかる構造に限定されるものではなく、たとえば、従来例の公報に記載されているように圧造成形機の駆動系に連動するカム機構などにより移動体の上部に固定された昇降ロッドを昇降させ、昇降ロッドの昇降により移動体14を昇降させるように構成してもよい。  In the above-described embodiment, the servo motor 21 and the ball screw 22 are used as the elevating mechanism 15. However, the structure is not limited to such a structure. For example, as described in the gazette of the conventional example, forging molding is performed. It may be configured that the lifting rod fixed to the upper part of the moving body is moved up and down by a cam mechanism interlocked with the drive system of the machine, and the moving body 14 is moved up and down by the lifting and lowering of the lifting rod.

その場合、バネ又は空圧、油圧により昇降ロッドに下方への押しつけ力を付加することにより、適性な掴持力を得ることができる。  In that case, an appropriate gripping force can be obtained by applying a downward pressing force to the lifting rod by a spring, pneumatic pressure, or hydraulic pressure.
