Description
本発明はプレス金型用ストリッピング装置に係り、より詳しくはプレス金型におけるパンチを用いた打孔作業において打孔後のパンチの後退移動時、前記パンチとパネルを分離させることにより、パネルが付いて上がることを防止するストリッピング装置の構造を改善することにより、作業の生産性及び効率性を向上させるように発明したものである。 The present invention relates to a stripping apparatus for a press die, and more particularly, in a punching operation using a punch in a press die, at the time of retreat movement of the punch after punching, by separating the punch and the panel, a panel is formed. The present invention has been made to improve the productivity and efficiency of work by improving the structure of a stripping device that prevents it from sticking up.
一般に、金型用カムユニットはプレス金型に装着されて垂直往復運動の作業方向を変えて角度運動することができるようにしたもので、図1のように、ボックス型のカムベース1の底面には前後方向にスライド移動可能なカムスライダー3が装着され、カムスライダー3にはリターンスプリング5を挿入することができるスプリング孔6が形成され、下部にはカムドライバー7が取り付けられる。 Generally, the cam unit for a mold is mounted on a press mold so that the work direction of the vertical reciprocating motion can be changed to perform an angular movement. As shown in FIG. A cam slider 3 slidable in the front-rear direction is mounted, a spring hole 6 into which a return spring 5 can be inserted is formed in the cam slider 3, and a cam driver 7 is attached to a lower portion.
前記のように構成されたカムユニットの作動過程は、図2のように、カムベース1全体が下降するにつれて、カムスライダー3の底面のスライド溝8がカムドライバー7の上面のスライド板9に沿ってガイド移動すれば、リターンスプリング5は弾性的に圧縮され、カムスライダー3が前進して、パンチ16がジグ14に固定装着されたパネルをパンチングするように構成されている。 As shown in FIG. 2, the operation process of the cam unit constructed as described above is such that the slide groove 8 on the bottom surface of the cam slider 3 moves along the slide plate 9 on the upper surface of the cam driver 7 as the whole cam base 1 descends. When the guide is moved, the return spring 5 is elastically compressed, the cam slider 3 moves forward, and the punch 16 punches a panel fixedly mounted on the jig 14.
しかし、前述した従来のカムユニットは、リターンスプリングの弾性復帰力のみによってパネル製品にパンチング作業を完了したパンチを反対方向に復帰させるように構成されているため、最近に引張強度が増加した高張力鋼板のようなパネル及び厚さの大きなパネルにおいては前記パンチとパネル間の摩擦抵抗が大きくなって復帰移動に問題が生じる場合が頻繁であって高速打抜きができないかカムスライダー又はパンチが破壊される問題点があった。 However, since the conventional cam unit described above is configured to return the punch which has completed the punching operation to the panel product in the opposite direction only by the elastic return force of the return spring, the high tensile strength which has recently increased the tensile strength is used. In the case of a panel such as a steel plate and a panel having a large thickness, frictional resistance between the punch and the panel becomes large, and a problem often occurs in a return movement, so that high-speed punching cannot be performed or a cam slider or a punch is broken. There was a problem.
したがって、前記問題点を解消するために、カムスライダーを復帰移動させるリターンスプリングの弾性を増大させて使っているが、前記高弾性スプリングの装着及び固定が難しく、カムユニットの作動中に前記高弾性力によって分離されて安全事故が発生する弊端があった。 Therefore, in order to solve the above problem, the return spring for returning the cam slider is used with an increased elasticity. However, it is difficult to attach and fix the high elasticity spring, and the high elasticity spring is used during operation of the cam unit. There was a problem that safety accidents occurred due to separation by force.
また、前記リターンスプリングの弾性が高い状態では、カムスライダーがカムドライバーに最初に接触する衝突瞬間に前方に移動しなければならないが、前記リターンスプリングの弾性によってスムーズに前方に移動することができなくて衝撃力が増加し、その後、カムドライバーの前進移動時にも接触面間の垂直面圧が増加して接触面の摩耗進行が加速してカム装置の寿命を縮める問題点があった。 Also, in the state where the elasticity of the return spring is high, the cam slider must move forward at the moment of collision when it first contacts the cam driver, but due to the elasticity of the return spring, it cannot move forward smoothly. As a result, the vertical force between the contact surfaces is increased even when the cam driver moves forward, and the wear of the contact surfaces is accelerated to shorten the life of the cam device.
前記のような従来技術の問題点を解決するためのもので、本発明は、打孔作業後にパンチとパネルをより簡便に分離させることができるようにするとともに前記カムスライダーの前面にパンチホルダー及びパンチが装着固定された状態でもパネルを押圧する押圧部材を入れ替えることができるようにすることにその目的がある。 The present invention is to solve the problems of the related art as described above, and the present invention enables a punch and a panel to be more easily separated after a punching operation, and a punch holder and a punch holder on a front surface of the cam slider. It is an object of the present invention to be able to replace a pressing member for pressing a panel even when a punch is mounted and fixed.
本発明の他の目的は、ディスクスプリングを適用して積層構造の安全性を確保しながらも、パネルの種類によって前記ディスクスプリングの積層構造及び個数を調整することにより、カムスライダーの復帰移動が円滑になされ、パンチ作業の効率性を向上させることができるようにすることにある。 Another object of the present invention is to adjust the laminated structure and the number of the disk springs according to the type of panel, while ensuring the safety of the laminated structure by applying a disk spring, so that the return movement of the cam slider is smooth. It is an object of the present invention to improve the efficiency of the punching operation.
本発明のさらに他の目的は、現存のパンチホルダーに直接装着することができ、内部に収容される押圧部材の装着及び分解が簡便であって組立工程及び使用の便宜性を向上させることができ、パンチ作業中に摩耗した押圧部材の入れ替えを速かに行って製品生産の効率性を高めるようにすることにある。 Still another object of the present invention is to directly mount the punch member on an existing punch holder, to easily install and disassemble the pressing member housed therein, and to improve the convenience of the assembling process and use. It is another object of the present invention to quickly replace a pressing member worn during a punching operation to enhance the efficiency of product production.

The present invention has been made to improve the productivity and efficiency of the work by improving the structure of the stripping device for preventing such a problem.
以下、本発明によるストリッピング装置の構成を添付図面に基づいて詳細に記述する実施例によってその特徴を理解することができるであろう。 Hereinafter, the features of the stripping apparatus according to the present invention will be understood by examples which describe the configuration of the stripping apparatus in detail with reference to the accompanying drawings.
まず、本発明で説明するストリッピング装置100はプレス金型用カムスライダー3の前方にパンチ16を含むパンチホルダー10に装着されるもので、ハウジング30の内部に弾性部材50及び押圧部材70を備え、パンチング作業中にパネルPに前記押圧部材70が接触して後方に押されるにつれて弾性部材50は弾性復元力を蓄積しながら圧縮され、パンチング作業を完了してカムスライダー3が後退すれば、前記弾性部材50の弾性復元力によって押圧部材70を前方に押し出すことにより、前記押圧部材70と接触したパネルPがパンチ16に付いて上がることを防止する構成を有する。 First, a stripping device 100 described in the present invention is mounted on a punch holder 10 including a punch 16 in front of a cam slider 3 for a press die, and includes an elastic member 50 and a pressing member 70 inside a housing 30. As the pressing member 70 comes into contact with the panel P and is pushed backward during the punching operation, the elastic member 50 is compressed while accumulating the elastic restoring force. When the punching operation is completed and the cam slider 3 retreats, By pressing the pressing member 70 forward by the elastic restoring force of the elastic member 50, the panel P in contact with the pressing member 70 is prevented from being attached to the punch 16 and raised.
このために、本発明によるストリッピング装置100は、まず円筒状のハウジング30の内部に可動板40、弾性部材50及び固定板60を順に挿入した後、前記固定板60が挿入された位置のハウジング30の先端を押し込んで互いに結束させる。 For this purpose, the stripping apparatus 100 according to the present invention firstly inserts the movable plate 40, the elastic member 50 and the fixed plate 60 into the cylindrical housing 30 in order, and then moves the housing at the position where the fixed plate 60 is inserted. 30 are pushed in and bound together.
これを図3〜図5に基づいて詳細に説明すれば、ハウジング30は、円筒状の内周面に押圧部材移動部31及び弾性部材収容部35が図面上の一側上部から他側下部側に連続的に形成され、他側の外周面には固定ホール39aを備えた支持部39が突設され、前記カムスライダー3の前面に固定ボルトを介して締結されて結合される。 This will be described in detail with reference to FIGS. 3 to 5. In the housing 30, the pressing member moving part 31 and the elastic member housing part 35 are arranged on the inner peripheral surface of the cylinder from the upper part on one side to the lower part on the other side. A support portion 39 having a fixing hole 39a protrudes from the outer peripheral surface on the other side, and is fastened to the front surface of the cam slider 3 via a fixing bolt to be joined thereto.
ここで、前記ハウジング30の押圧部材移動部31は弾性部材収容部35より小さな大きさを持って連結されることによって前記連結部は段面を有することになるので、前記弾性部材収容部35に挿入される可動板40が前記段面にかかって移動が阻止される。 Here, since the pressing member moving portion 31 of the housing 30 is connected with a smaller size than the elastic member receiving portion 35, the connecting portion has a stepped surface. The movable plate 40 to be inserted is hung on the stepped surface and is prevented from moving.
すなわち、前記可動板40は弾性部材収容部35と同じ外形を有し、中央にはパンチ16の通過する孔が形成され、ハウジング30の他側から弾性部材収容部35に挿入され、押圧部材移動部31に連結された段面にかかれて支持される。 That is, the movable plate 40 has the same outer shape as the elastic member accommodating portion 35, a hole through which the punch 16 passes is formed in the center, and the movable plate 40 is inserted into the elastic member accommodating portion 35 from the other side of the housing 30 to move the pressing member. It is supported on a step surface connected to the portion 31.

By pushing one end of the housing 30 into which the inclined surface 61 is pushed in, the inclined surface 61 is applied to the inner peripheral surface of the fixing plate insertion groove 36 to be united.
また、固定板60がハウジング30に押し入れられて一体に結束される他の実施例を説明すれば、図6のように、弾性部材収容部35の他側先端の内周面に断面凹形の固定板挿合溝37を形成し、固定板60の外周面に前記固定板挿合溝37に対応する断面凸形の固定板挿合突条62を形成し、前記固定板60を弾性部材収容部35の内側に締まりばめ方式で押し入れて互いに結束させるものも本発明に含まれる。 Further, another embodiment in which the fixing plate 60 is pushed into the housing 30 and bound together will be described. As shown in FIG. 6, the inner peripheral surface of the other end of the elastic member accommodating portion 35 has a concave cross section. A fixing plate insertion groove 37 is formed, and a fixing plate insertion protrusion 62 having a convex cross section corresponding to the fixing plate insertion groove 37 is formed on the outer peripheral surface of the fixing plate 60, and the fixing plate 60 is accommodated by an elastic member. The present invention also includes a structure in which the members are pressed into the inside of the portion 35 by an interference fit method and bound together.
そして、前記弾性部材収容部35は、固定板挿合溝37の先端部が外側に広がっているように加工した後、前記固定板60を挿入して固定板挿合溝37に固定板挿合突条62を位置させ、前記ハウジング30の一側を押し込んで凹凸結合させることによって一体に結束することが好ましい。 The elastic member receiving portion 35 is processed so that the distal end of the fixed plate insertion groove 37 is widened outward, and then the fixed plate 60 is inserted into the fixed plate insertion groove 37. It is preferable that the protrusions 62 are positioned, and one side of the housing 30 is pushed in to form a concave and convex connection, thereby uniting the housing 30 integrally.
ここで、前記固定板挿合溝37及び固定板挿合突条62は断面“U”形又は断面“V”形のように多様に成形することができる。ハウジング30の弾性部材収容部35に可動板40及び弾性部材50が収納された状態でハウジング30に固定板60を押し入れてから端部を押し込むことによって一体に構成することにより、収納された可動板40及び弾性部材50が分離されないようにすることが重要である。 Here, the fixing plate insertion groove 37 and the fixing plate insertion protrusion 62 can be formed in various shapes such as a “U” cross section or a “V” cross section. When the movable plate 40 and the elastic member 50 are housed in the elastic member accommodating portion 35 of the housing 30, the fixed plate 60 is pushed into the housing 30, and then the end portion is pushed in to integrally form the movable plate 40.

After the pressing member 70 is inserted so as to be slidable along, the fixing member 80 is attached to the distal end of the pressing member moving portion 31 to prevent the pressing member 70 from being separated.
前記押圧部材70は、中央にパンチ16が移動する長手方向へのピン貫通ホール73が成形され、ハウジング30の一側から押圧部材移動部31にスライド移動可能に挿入されて前記可動板40と当接するガイド部71と、前記ガイド部71より小さな直径を有する突出部72とが一体に成形される。前記突出部72は押圧部材移動部31より外側に突出するように形成される。 The pressing member 70 is formed with a pin through hole 73 in the longitudinal direction in which the punch 16 moves in the center, and is slidably inserted into the pressing member moving part 31 from one side of the housing 30 to contact the movable plate 40. The contacting guide portion 71 and the projecting portion 72 having a smaller diameter than the guide portion 71 are integrally formed. The protruding portion 72 is formed to protrude outward from the pressing member moving portion 31.
すなわち、ハウジング30の押圧部材移動部31に押圧部材70のガイド部71が挿入されて可動板40に支持された初期状態で、前記押圧部材70が離脱することを防止するために、ガイド部71の前方位置の前記押圧部材移動部31の内周面にリング挿合溝32を形成し、前記ガイド部71の外径より小さな内径を有する固定リング80を前記リング挿合溝32に着脱可能に結合することで、前記押圧部材70のガイド部71が固定リング80にかかることにより、ガイド部71が一側方向に分離されることを防止することができる。 That is, in the initial state in which the guide portion 71 of the pressing member 70 is inserted into the pressing member moving portion 31 of the housing 30 and is supported by the movable plate 40, the guide portion 71 is prevented from being detached. A ring insertion groove 32 is formed on the inner peripheral surface of the pressing member moving portion 31 at the front position of the fixing member 80 so that a fixing ring 80 having an inner diameter smaller than the outer diameter of the guide portion 71 can be detachably attached to the ring insertion groove 32. By being connected, the guide portion 71 of the pressing member 70 can be prevented from being separated in one side direction by being engaged with the fixing ring 80.
そして、ハウジング30の押圧部材移動部31には回転防止面33が突設され、前記押圧部材移動部31の内面に沿ってスライド移動する押圧部材70のガイド部71には前記回転防止面33に対応する回転阻止面71aが成形されることにより、前記押圧部材70が挿入された状態ではスライド移動のみ可能である。 The rotation preventing surface 33 is protruded from the pressing member moving portion 31 of the housing 30. The guide portion 71 of the pressing member 70 that slides along the inner surface of the pressing member moving portion 31 has the rotation preventing surface 33. By forming the corresponding rotation preventing surface 71a, only sliding movement is possible in a state where the pressing member 70 is inserted.
また、前記押圧部材移動部31を備えたハウジング30の外側面には前記リング挿合溝32と連通する工具挿入溝34がさらに形成され、前記工具挿入溝34を通して工具を挿入して、リング挿合溝32に装着された固定リング80を持ち上げることで固定リングを簡便に分離させることができる。 In addition, a tool insertion groove 34 communicating with the ring insertion groove 32 is further formed on an outer surface of the housing 30 having the pressing member moving portion 31, and a tool is inserted through the tool insertion groove 34 to insert a ring. By lifting the fixing ring 80 attached to the mating groove 32, the fixing ring can be easily separated.
また、前記固定リング80はこの実施例で断面円形に成形されているが、図6のように、一般的なスナップリング81を使うこともできる。この場合、スナップリング81の形状に対応するように断面方形のリング挿合溝32が成形される。 Although the fixing ring 80 is formed in a circular cross section in this embodiment, a general snap ring 81 can be used as shown in FIG. In this case, the ring insertion groove 32 having a rectangular cross section is formed so as to correspond to the shape of the snap ring 81.
このように構成された本発明によるストリッピング装置100の実施例を添付図4及び図5に基づいて説明すれば、まずパンチ16を備えたパンチホルダー10にハウジング30の支持部39を、固定ボルトを固定ホール39aを通してパンチホルダー10に締結することによって結合させる。 An embodiment of the stripping apparatus 100 according to the present invention will be described with reference to FIGS. 4 and 5. First, the support portion 39 of the housing 30 is attached to the punch holder 10 having the punch 16 by fixing bolts. Are fixed to the punch holder 10 through the fixing holes 39a.
ここで、前記パンチ16はハウジング30の固定板60、弾性部材50、可動板40を貫通して押圧部材70のピン貫通ホール73の内部に位置し、パンチング作業のためにパンチホルダー10が前方に移動すれば、パネルPに前記押圧部材70の突出部72が先に接触する。 Here, the punch 16 penetrates through the fixed plate 60, the elastic member 50, and the movable plate 40 of the housing 30, and is located inside the pin through hole 73 of the pressing member 70, and the punch holder 10 is moved forward for punching work. When the panel P moves, the protruding portion 72 of the pressing member 70 comes into contact with the panel P first.
そして、前記パンチホルダー10がさらに前方に移動すれば、押圧部材70の突出部72がパネルPによって押されて後方に移動するにつれて、押圧部材70が可動板40を押圧し、弾性部材50は弾性復元力を蓄積しながら圧縮され、ピン貫通ホール73の内部に位置するパンチ16は外部に突出してパネルPにパンチング作業を行う。 If the punch holder 10 moves further forward, as the protrusion 72 of the pressing member 70 is pushed rearward by the panel P, the pressing member 70 presses the movable plate 40, and the elastic member 50 becomes elastic. The punch 16 which is compressed while accumulating the restoring force and located inside the pin through-hole 73 protrudes outside to perform a punching operation on the panel P.
その後、パンチング作業が完了した状態では、前記カムスライダー3に結合されたパンチホルダー10及びハウジング30が後退して初期状態に移動するにつれて、圧縮状態の弾性部材50が押圧部材70を前方に押し出すことになる。 Thereafter, when the punching operation is completed, the compressed elastic member 50 pushes the pressing member 70 forward as the punch holder 10 and the housing 30 coupled to the cam slider 3 retreat and move to the initial state. become.
すなわち、前記弾性部材50の弾性力によって可動板40が前方に移動しながら押圧部材70のガイド部71をスライド移動させ、前記押圧部材70は固定リング80にガイド部71がかかられて移動が阻止される。 That is, while the movable plate 40 is moved forward by the elastic force of the elastic member 50, the guide portion 71 of the pressing member 70 is slid and moved. Will be blocked.
したがって、前記パンチング作業後のカムスライダー3の後退移動時、パンチ16との摩擦などによって付いて上がるパネルPを前記押圧部材70が前方に押し出すことによってパネルを安定的に分離させることができる。 Therefore, when the cam slider 3 moves backward after the punching operation, the pressing member 70 pushes the panel P, which is attached due to friction with the punch 16, forward, so that the panel can be separated stably.
そして、前記のようにパネルに接触する押圧部材70は、パネルの損傷を防止するために、パネルに比べて軟質の金属材から突出部72を成形する。長期間パンチング作業を行えば前記突出部72が摩耗するから、新しい押圧部材70に入れ替えなければならない。 The pressing member 70 that contacts the panel as described above forms the protrusion 72 from a metal material that is softer than the panel in order to prevent damage to the panel. If the punching operation is performed for a long period of time, the protruding portion 72 will be worn out.
前記入れ替え作業のためには、まずカムスライダー3を後退移動させてハウジング30の前方に押圧部材70の突出部72が突出するようにした後、別途の工具を用いてリング挿合溝32に装着された固定リング80を分離させる。 For the replacement work, first, the cam slider 3 is moved backward so that the protruding portion 72 of the pressing member 70 protrudes forward of the housing 30, and then the cam slider 3 is mounted on the ring insertion groove 32 using a separate tool. The separated fixing ring 80 is separated.
これにより、押圧部材70のガイド部71は押圧部材移動部31に沿って前方にスライド移動してハウジング30から分離され、新しい押圧部材70のガイド部71を前記押圧部材移動部31に沿って挿入した後、リング挿合溝32に固定リング80を装着することで入れ替え作業を簡便に完了する。 As a result, the guide portion 71 of the pressing member 70 slides forward along the pressing member moving portion 31 and is separated from the housing 30, and the guide portion 71 of the new pressing member 70 is inserted along the pressing member moving portion 31. After that, the replacement work is simply completed by attaching the fixing ring 80 to the ring insertion groove 32.
以上のように、上述した実施例は本発明の最良の実施形態について説明したものであるが、前記実施例のみに限定されるものではなく、本発明の技術思想を逸脱しない範疇内で多様な変形が可能であるのは当業者に明らかなものである。
