本発明は、曲げ装置に係り、更に詳しくは、ベースフレームの上部に配設されて折曲げ面が形成された折曲げ型の周縁部に被加工物が載置され、前記折曲げ型の下部に配設された受け案内板のガイド孔に沿って移動しながら前記被加工物を押圧して折曲げ部を成形する折曲げ成形手段が前記受け案内板の下部に配設された伝動手段により作動されて曲げ作業が自動化され、前記折曲げ型は、前記受け案内板から上部に突出した支柱体に多数配設され、昇降手段により上動する上型と、垂直フレームに固定された下型と、により構成され、前記上型及び下型にはそれぞれ上治具及び下治具が係合されて、同じ高さの被加工物はもとより、異なる高さの被加工物を同時に多数成形することができ、前記折曲げ成形手段には多数の成形シリンダー付き成形シリンダー部が形成されて前記被加工物に折曲げ部を成形可能にする曲げ装置に関する。 The present invention relates to a bending apparatus, and more specifically, a workpiece is placed on a peripheral portion of a bending die disposed on an upper portion of a base frame and having a bending surface formed thereon, and a lower portion of the bending die. And a bending means for pressing the workpiece while moving along the guide hole of the receiving guide plate disposed at the lower portion of the receiving guide plate to form a bent portion. The bending operation is automated to be operated, and the bending dies are arranged on a large number of columns projecting upward from the receiving guide plate and are moved upward by the raising and lowering means, and the lower dies fixed to the vertical frame The upper jig and the lower jig are respectively engaged with the upper mold and the lower mold to simultaneously form a large number of workpieces of different heights as well as workpieces of the same height. Said bending and forming means are provided with a number of forming cylinders Said shaped cylinder portion is formed on Bending device enables forming a bent portion on the workpiece.
一般に、室内の窓を通して入射する光を遮断したり、外部から室内を覗き見ることを防いだりするために、カーテンが固定されるカーテンレールが形成される。 In general, a curtain rail is formed to which a curtain is fixed in order to block incident light through the window in the room and to prevent the user from looking into the room from the outside.
この種のカーテンレールは直線状に形成される場合もあるが、トラックなどの大型車の内部やシャワー室、病院の入院室、有料自習室の場合には光を遮断することはもとより、それぞれの独立した空間を確保するために曲線部が形成されたカーテンレールが設置される。 Curtain rails of this type are sometimes formed in a straight line, but in the case of large vehicles such as trucks, shower rooms, hospital admission rooms, and chargeable study rooms, it is important to block the light, as well as A curtain rail having a curved portion is installed to secure an independent space.
このため、前記カーテンレールは、金属製に押出成形した後、設置しようとする場所に応じて曲げ成形し、このようなカーテンレールを所望の形状に曲げ成形するためには、通常、片面に内側に向かって凹んだ成形溝が形成された曲げダイに押出成形したバー（ｂａｒ）状のカーテンレールを載せた状態で前記曲げダイの成形溝と対応する形状に形成された曲げパンチを成形溝に向かって付勢してカーテンレールを設置しようとする場所に合うように曲げ成形することになる。 For this reason, the curtain rail is extruded into metal and then bent according to the place to be installed, and in order to bend such a curtain rail into a desired shape, the inside is usually on one side. Forming a bending punch formed in a shape corresponding to the forming groove of the bending die in a state where the bar-like curtain rail extruded is placed on the bending die in which the forming groove recessed toward the side is formed It will be bent toward the place where it is going to install it to bias the curtain rail.
しかしながら、従来の通常の曲げ装置を用いて互いに対称となる折曲げ部を成形する場合、前記カーテンレールの一方の側を曲げ成形した後、他方の側を曲げ成形する過程を行うが故に、折曲げ部が均一に対称的なカーテンレールを製作することが非常に困難であるという問題があった。 However, in the case of forming the bending portions to be symmetrical with each other using a conventional ordinary bending device, after one side of the curtain rail is formed by bending, the other side is formed by bending. There is a problem that it is very difficult to manufacture a curtain rail in which the bending portion is uniformly symmetrical.
特に、従来の曲げ装置の場合には、バー（ｂａｒ）状のカーテンレールを曲げダイに設置した後にも、作業者が曲げパンチをマニュアルで作動させるが故に、作業能率が低下することはもとより、曲げ成形したカーテンレールの不良の発生率が高く、しかも作業速度も遅いが故に、カーテンレールの生産性が低下するという問題があった。 In the case of the conventional bending apparatus, in particular, the operator manually operates the bending punch even after the bar-shaped curtain rail is installed on the bending die, so that the working efficiency is lowered, of course. There is a problem that the productivity of the curtain rail is lowered because the incidence rate of defects of the bent and formed curtain rail is high and the working speed is slow.
このような問題は、カーテンレールだけではなく、様々な分野において採用される金属製パイプの曲げ成形にも同様に見受けられる。 Such problems are seen not only in curtain rails but also in bending of metal pipes employed in various fields.
上述したような問題を克服するために、本出願人は、大韓民国登録特許第１０−１０１７８１０号（「曲げ装置」、以下、先登録特許と称する。）を提案している。これは、被加工物の両端部を対称となるように曲げ成形する曲げ装置に関するものであり、ベースフレームの上部に配設されてバー状の被加工物が載置される載置溝が周縁部に沿って形成され、前記被加工物の両側部に第１及び第２の折曲げ部を成形するための第１及び第２の突出折曲げ面が対称となるように形成される折曲げ型と、前記折曲げ型が上部に設けられ、前記折曲げ型の第１及び第２の突出折曲げ面に沿って所定の距離だけ離間して第１のガイド孔が形成される作業台と、前記作業台の第１のガイド孔に沿って対称となるように移動して前記被加工物の露出面を押圧して第１及び第２の折曲げ部をそれぞれ成形する第１及び第２の折曲げ成形手段と、前記第１及び第２の折曲げ成形手段を前記第１のガイド孔に沿って移動させる伝動手段と、により構成されることを特徴とする。 In order to overcome the above-mentioned problems, the applicant has proposed Korean Patent No. 10-101810 ("Bending apparatus", hereinafter referred to as "pre-registered patent").

以下、本発明に係る曲げ装置１の作動過程について説明する。 Hereinafter, the operation process of the bending device 1 according to the present invention will be described.
このとき、本発明に係る曲げ装置１は、被加工物２０に２つの折曲げ部２１、２２が成形される過程について説明する。 At this time, in the bending apparatus 1 according to the present invention, a process of forming the two bent portions 21 and 22 on the workpiece 20 will be described.
図８ａから図８ｃは、本発明の曲げ装置の作動状態図である。 Figures 8a to 8c show the operating state of the bending device according to the invention.
まず、ベースフレーム１０の受け案内板２００の上部に固定される複数の折曲げ型１００の上型１１０と下型１２０との間にバー（ｂａｒ）状の被加工物２０を嵌め込む。 First, a bar-shaped workpiece 20 is fitted between the upper mold 110 and the lower mold 120 of the plurality of bending dies 100 fixed to the upper portion of the receiving and guiding plate 200 of the base frame 10.
このとき、前記上型１１０を上動させた状態で被加工物２０を前記下型１２０の周縁部に載置し、前記上型１１０を下動させて前記被加工物２０が前記上型１１０と下型１２０との間に固定されるようにする。 At this time, the workpiece 20 is placed on the peripheral portion of the lower mold 120 in a state in which the upper mold 110 is moved upward, and the workpiece 20 is moved to the upper mold 110 by moving the upper mold 110 downward. It is fixed between the lower mold 120 and the lower mold 120.
このとき、前記被加工物２０の高さに応じて前記上治具及び下治具１１２、１２２を選択的に取り替える。 At this time, the upper and lower jigs 112 and 122 are selectively replaced according to the height of the workpiece 20.
また、前記受け案内板２００の中間に形成された押圧手段８００の押圧シリンダー８３０により押圧具８２０とボルト締めされた押圧支持竿８１０を前進させて前記押圧具８２０が前記被加工物２０を押圧して固定する。 Further, the pressing support rod 810 which is bolted with the pressing tool 820 is advanced by the pressing cylinder 830 of the pressing means 800 formed in the middle of the receiving guide plate 200, and the pressing tool 820 presses the workpiece 20. Fix it.
このような状態で、前記伝動手段７００のシリンダー手段７１０を駆動すると、前記シリンダー手段７１０のピストン７１１が前進しながら前記ピストン７１１と一体に形成されたラック部材７２０が前進するが、このとき、前記ラック部材７２０の両側に形成される第１及び第２のラック７２２ａ、７２２ｂが前進しながら前記第１及び第２のラック７２２ａ、７２２ｂが噛合される第１及び第２のピニオン７３０ａ、７３０ｂが回転し、これにより、前記第１及び第２のピニオン７３０ａ、７３０ｂがそれぞれ軸結合された前記第１及び第２の駆動スプロケット７４０ａ、７４０ｂが回転する。 In such a state, when the cylinder means 710 of the transmission means 700 is driven, the rack member 720 integrally formed with the piston 711 is advanced while the piston 711 of the cylinder means 710 is advanced. The first and second pinions 730a and 730b are engaged with the first and second racks 722a and 722b while the first and second racks 722a and 722b formed on both sides of the rack member 720 are advanced. As a result, the first and second drive sprockets 740a and 740b, to which the first and second pinions 730a and 730b are axially coupled, respectively, are rotated.
更に、第１及び第２の駆動スプロケット７４０ａ、７４０ｂと第１及び第２のチェーン７６０ａ、７６０ｂにより連動された第１及び第２の従動スプロケット７５０ａ、７５０ｂが一緒に回転することにより、前記第１及び第２のチェーン７６０ａ、７６０ｂが移動し、前記第１及び第２のチェーン７６０ａ、７６０ｂと連結された第１及び第２の折曲げ成形手段５００ａ、５００ｂが前記受け案内板２００のガイド孔２１０に沿って移動する。 Further, the first and second driven sprockets 740a and 740b and the first and second driven sprockets 750a and 750b interlocked by the first and second chains 760a and 760b rotate together. And the second chains 760a and 760b are moved, and the first and second bending and forming means 500a and 500b connected to the first and second chains 760a and 760b are guide holes 210 of the receiving and guiding plate 200. Move along.
このとき、第１の成形シリンダー部５２０ａのピストンが同時に前進しながらピストンの先端に形成された第１の押圧ローラー５２１ａが前記被加工物２０を押圧密着させながら移動し、前記折曲げ型１００の折曲げ面１０１を通りながら前記被加工物２０に折曲げ部２１を成形する。 At this time, while the piston of the first forming cylinder portion 520 a advances simultaneously, the first pressing roller 521 a formed at the tip of the piston moves while pressing the workpiece 20 in close contact with the bending die 100. The bending portion 21 is formed on the workpiece 20 while passing through the bending surface 101.
更にまた、前記第２の成形シリンダー部５２０ｂのピストンが同時に前進しながら第２の押圧ローラー５２１ｂが前記被加工物２０を押圧密着させながら移動し、前記折曲げ型１００の折曲げ面１０２を通りながら前記被加工物２０に他の折曲げ部２２を成形する。 Furthermore, while the piston of the second forming cylinder portion 520b advances simultaneously, the second pressing roller 521b moves while pressing and bringing the work 20 into close contact, and passes through the bending surface 102 of the bending die 100. At the same time, another bent portion 22 is formed on the workpiece 20.
このような曲げ作業が終わった後、前記伝動手段７００のシリンダー手段７１０を逆駆動すると、前記シリンダー手段７１０のピストン７１１が後進しながら前記ラック部材７２０が後進して、前記第１及び第２の折曲げ成形手段５００ａ、５００ｂは元の位置に戻る。つまり、前記成形過程とは逆に駆動されて前記第１及び第２の折曲げ成形手段５００ａ、５００ｂが元の状態に戻る。 After such a bending operation is completed, when the cylinder means 710 of the transmission means 700 is reversely driven, the rack member 720 moves backward while the piston 711 of the cylinder means 710 moves backward, so that the first and second The bending and forming means 500a, 500b return to their original positions. That is, the first and second bending and forming means 500a and 500b are returned to the original state by being driven reversely to the forming process.
したがって、一回の曲げ作業で多数の被加工物２０を同時に成形することができることはもとより、前記上治具及び下治具１１２、１２２を取り替えて高さが異なる被加工物２０も同時に成形することができ、様々な産業現場で使用するパイプ、金属線材などをより手軽に且つ迅速に成形することが可能になる。 Therefore, not only can a plurality of workpieces 20 be formed simultaneously in one bending operation, but also the upper and lower jigs 112 and 122 are replaced to simultaneously form workpieces 20 having different heights. It is possible to form pipes, metal wires and the like used in various industrial sites more easily and quickly.
以上述べたような実施形態は、本発明の最も好適な例について説明したものに過ぎず、本発明が前記実施形態にのみ限定されることはなく、本発明の技術的思想を逸脱しない範囲内において様々な変形が可能であるということは当業者にとって自明である。
The embodiment as described above is only for explaining the most preferable example of the present invention, and the present invention is not limited only to the above embodiment, and within the scope not departing from the technical concept of the present invention. It is obvious to one skilled in the art that various modifications are possible in
