Description

유연한 성형 롤러를 구비한 무금형 판재 성형 장치Moldless plate forming apparatus with flexible forming roller
본 발명은 무금형 판재 성형 장치에 관한 것으로, 더 상세하게는 곡률 변경이 가능한 유연한 성형 롤러를 이용하는 다품종 소량 판재 성형에 적합한 무금형 판재 성형 장치에 관한 것이다.The present invention relates to a die-less plate forming apparatus, and more particularly to a die-less plate forming apparatus suitable for forming a small variety of sheet type using a flexible forming roller capable of changing the curvature.
일반적으로, 후판 또는 박판 등의 판재를 성형하기 위해서는 도 1에 도시된 바와 같이 상부와 하부에 목적 형상에 부합하는 금형(1)을 제작하여 그 사이에 판재(3)를 배치한 후 프레스 장치를 이용하여 판형 제품을 성형 및 제작하였다.Generally, in order to mold a plate such as a thick plate or a thin plate, as shown in FIG. 1, a mold 1 corresponding to a target shape is manufactured on the upper and lower portions thereof, and then the press apparatus is placed therebetween. Plate-shaped products were molded and fabricated.
그러나, 이러한 종래의 금형을 이용한 판재 성형 장치는 동일한 곡면 형상을 갖는 제품의 대량 생산은 가능하나, 목적 형상이 수정되거나 변경되는 경우 이를 반영하기 위해서는 새로운 금형을 제작하여야 하므로 금형 설계비 및 최종 제품의 생산 단가가 증가하게 되어 다품종 소량 생산에는 적합하지 않았다. 또한, 목적 형상이 수정되지 않더라도, 금형을 한시적 또는 영구적으로 사용하지 않는 경우 보관, 유지보수 및 폐기 등으로 인한 추가적인 비용이 발생하였다. However, the plate forming apparatus using the conventional mold is capable of mass production of products having the same curved shape, but in order to reflect the modified or changed object shape, a new mold must be manufactured so that the mold design cost and the production of the final product can be obtained. As the unit price increased, it was not suitable for small quantity production of various kinds. In addition, even if the target shape is not modified, additional costs are incurred due to storage, maintenance and disposal if the mold is not used temporarily or permanently.
이러한 문제를 해결하기 위하여, 특허등록 제10-1034592호 등에서는, 도 2와 같이 상부 금형(11a) 및 하부 금형(11b)이 각각 개별적으로 상하이동 가능하게 구성된 다수의 펀치로 이루어진 다점 판재 성형 장치를 개시하고 있다. 이러한 다점 판재 성형 장치는 목적 형상이 수정되거나 변경되었을 때 상하부금형의 펀치의 높이를 조절하여 성형 형상을 용이하게 변경할 수 있다. 그러나, 각각의 펀치 헤드의 곡률반경과 펀치들 간의 높이차로 인하여 판재와 성형 장치 사이에 불규칙한 공간이 발생하게 되며, 이로 인해 국부적으로 작은 곡률반경을 가지는 곡면이나 모서리를 갖는 곡면의 성형이 어렵고 판재의 가장자리는 성형이 잘 되지 않아 잘라냄으로써 소재의 낭비를 초래하는 문제가 있었다. 또한, 판재의 두께가 비교적 두꺼운 후판의 경우와는 달리, 두께가 얇은 박판을 성형하는 경우 각 펀치의 크기에 따라 딤플(dimple)이 발생하거나 국부적으로 주름(wrinkle)이 발생하는 문제점이 있었다. 이를 해결하기 위하여 도 3에 도시된 바와 같이 다수의 성형 펀치(21a, 21b)와 판재(23) 사이에 우레탄 등의 소재로 형성된 탄성패드(25)를 배치하여 성형하는 방법이 개발되었으나, 탄성패드의 재질과 목적 형상에 따라 각각의 펀치 길이를 재조정하여야 하여 역시 장치의 운용이나 성형 정밀도를 저하시키는 단점이 있었다. In order to solve this problem, in Patent Registration No. 10-1034592, etc., as shown in Fig. 2, the upper die (11a) and lower die (11b) is a multi-point plate forming apparatus consisting of a plurality of punches each configured to be individually movable It is starting. Such a multi-point plate forming apparatus can easily change the molding shape by adjusting the height of the upper and lower mold punches when the target shape is modified or changed. However, due to the curvature radius of each punch head and the height difference between the punches, an irregular space is generated between the sheet material and the forming apparatus, which makes it difficult to form a curved surface or a curved surface having a locally small curvature radius. The edges are not well formed, there is a problem that causes the waste of the material by cutting. In addition, unlike the case of a thick plate having a relatively thick plate, when forming a thin thin plate, dimples or local wrinkles occur according to the size of each punch. In order to solve this problem, as shown in FIG. 3, a method of forming and forming an elastic pad 25 formed of a material such as urethane between the plurality of forming punches 21a and 21b and the plate member 23 has been developed. Each punch length has to be readjusted according to the material and the shape of the object.
또한, 종래의 금형 성형 장치와 다수의 펀치를 이용한 다점 성형 장치는 금형의 크기에 따라 판재의 최종 형상의 크기가 제한되어, 대형 판재를 성형하기 위해서는 최종 형상을 분할 성형하여 추가적인 기계적 가공 및 용접 등에 의한 접합을 통하여 최종 제품을 제조하거나, 판재에 직접 열을 가하여 열에 의해 발생하는 잔류응력을 이용하여 곡면을 성형하였다. 그러나, 이러한 추가적인 가공 등은 성형 비용 및 기간을 증가시키는 요인이 되었다.In addition, in the conventional mold forming apparatus and a multi-point molding apparatus using a plurality of punches, the size of the final shape of the plate is limited according to the size of the mold. In order to form a large plate, the final shape is divided and molded to further mechanical processing and welding. The final product was manufactured by joining or by directly applying heat to the plate to form a curved surface using residual stress generated by heat. However, such additional processing has been a factor in increasing the molding cost and duration.
따라서, 본 발명은 상기한 문제점을 해결하여 단순한 구성으로 목적 형상이 변경되더라도 용이하게 성형 형상을 수정할 수 있어 다품종 소량 판재 성형에 적합하면서 딤플이나 주름을 유발하지 않는 무금형 판재 성형 장치를 제공하는 것을 목적으로 한다.Accordingly, the present invention is to solve the above problems and to provide a die-less plate forming apparatus that can be easily modified even if the target shape is changed to a simple configuration, suitable for forming a small quantity of various varieties and does not cause dimples or wrinkles The purpose.
또한, 본 발명은 소재의 가장자리까지 성형이 가능하고 판재의 두께나 크기에 제한이 없이 성형이 가능한 무금형 판재 성형 장치를 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide a moldless plate forming apparatus that can be molded to the edge of the raw material and can be molded without limiting the thickness or size of the plate.
상기한 목적을 달성하기 위한 본 발명에 따른 무금형 판재 성형 장치는, 상하로 대응되게 배열되고, 각각 다양한 곡률로 휘어질 수 있는 두 개의 회전가능한 성형 롤러와; 각 성형 롤러에 일단이 고정되고, 길이 조절이 가능하도록 구성되어, 길이에 따라 상기 성형 롤러의 곡률과 두 개의 성형 롤러 사이의 간격을 조절하는 다수의 롤러 조절 부재;를 포함하며, 상기 롤러 조절 부재에 의하여 성형 롤러의 곡률 및 간격을 조절함으로써 판재의 성형 형태가 달라지는 것을 특징으로 한다. An apparatus for forming a dieless plate according to the present invention for achieving the above object includes: two rotatable forming rollers arranged up and down correspondingly, each of which may be bent at various curvatures; One end is fixed to each forming roller, is configured to be adjustable in length, a plurality of roller adjusting member for adjusting the curvature of the forming roller and the distance between the two forming roller according to the length; includes; By controlling the curvature and the gap of the forming roller by the form of the sheet material is characterized in that it is changed.
즉, 본 발명에 따른 무금형 판재 성형 장치는 상하로 놓인 두 개의 성형 롤러 사이에서 판재를 성형하므로 구성이 간단할 뿐 아니라 길이 방향으로 판재의 크기에 제한이 없이 성형이 가능하고, 롤러 조절 부재에 의하여 성형 롤러의 곡률 및 간격을 조절하여 간단히 성형 형태를 수정할 수 있어 다품종 소량 판재 성형에 적합하다.That is, the moldless plate forming apparatus according to the present invention forms a plate between the two forming rollers placed up and down, not only the configuration is simple but also can be formed without limiting the size of the plate in the longitudinal direction, the roller adjustment member By adjusting the curvature and spacing of the forming roller it is possible to simply modify the molding form, which is suitable for forming small quantities of various types of plate.
바람직하게는, 상기 롤러 조절 부재는 내부 나사산을 가진 외부 부재 및 외부 나사산을 가진 내부 부재를 포함하여, 외부 부재와 내부 부재의 나사 결합 길이에 따라 롤러 조절 부재의 길이가 조절된다. Preferably, the roller adjusting member includes an outer member having an inner thread and an inner member having an outer thread, so that the length of the roller adjusting member is adjusted according to the screw engagement length of the outer member and the inner member.

이하, 본 발명을 첨부된 도면을 참조한 실시예를 통하여 더 상세히 설명한다. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도 4는 본 발명의 일 실시예에 따른 무금형 판재 성형 장치(100)를 개략적으로 도시한 도면이다. 도시된 바와 같이, 본 발명에 따른 판재 성형 장치(100)에는 수평으로 배열된 두 개의 성형 롤러(101a, 101b)가 서로 상하로 대응되게 배치된다. 이 성형 롤러(101a, 101b)는 각각 다양한 곡률로 유연하게 휘어질 수 있도록 구성된다. 4 is a view schematically showing a die-less plate forming apparatus 100 according to an embodiment of the present invention. As shown, in the sheet forming apparatus 100 according to the present invention, two forming rollers 101a and 101b arranged horizontally are arranged to correspond to each other up and down. These forming rollers 101a and 101b are each configured to bend flexibly with various curvatures.
각 성형 롤러(101a, 101b)에는 곡률을 조절하기 위하여 다수의 롤러 조절 부재(103)가 설치되는데, 도 5에는 상기 롤러 조절 부재(103)의 일 예가 도시되어 있으며, 도 6에는 이를 일부 단면도로써 더 구체적으로 도시하고 있다. 도시된 롤러 조절 부재(103)는 내부 나사산을 가진 외부 부재(105)와 외부 나사산을 가진 내부 부재(107)를 포함하여, 내부 부재(107)가 외부 부재(105)에 끼워져 나사결합되도록 구성되며, 외부 부재(107)와 내부 부재(105)의 나사 결합된 길이에 따라 롤러 조절 부재(103)의 길이가 조절된다. Each of the forming rollers 101a and 101b is provided with a plurality of roller adjusting members 103 to adjust the curvature, and an example of the roller adjusting member 103 is shown in FIG. More specifically shown. The illustrated roller adjustment member 103 includes an outer member 105 with an inner thread and an inner member 107 with an outer thread, so that the inner member 107 is fitted to the outer member 105 and screwed therein. The length of the roller adjusting member 103 is adjusted according to the screwed length of the outer member 107 and the inner member 105.
롤러 조절 부재(103)는 또한 길이 조절을 용이하게 하기 위하여 도 6에 도시된 바와 같이 모터에 연결될 수 있다. 즉, 외부 부재(105)는 성형 롤러에 고정되고 내부 부재(107)는 모터에 연결되어, 모터의 회전에 의해 내부 부재(103)의 외부 부재(105)에 대한 결합 깊이가 달라져 롤러 조절 부재(103)의 전체적인 길이가 조절된다. 이때, 각각의 롤러 조절 부재(103)에는 별도의 모터가 제공될 수 있으나, 도 7에 도시된 바와 같이 하나 또는 다수의 모터가 이동하면서 다수의 롤러 조절 부재(103)를 조절하도록 구성될 수도 있다. The roller adjusting member 103 may also be connected to the motor as shown in FIG. 6 to facilitate length adjustment. That is, the outer member 105 is fixed to the forming roller and the inner member 107 is connected to the motor, the engagement depth of the inner member 103 to the outer member 105 is changed by the rotation of the motor, so that the roller adjusting member ( The overall length of 103 is adjusted. At this time, each roller adjusting member 103 may be provided with a separate motor, but may be configured to adjust the plurality of roller adjusting members 103 while moving one or a plurality of motors as shown in FIG. .
따라서, 하나 또는 다수의 모터에 의해 각각의 내부 부재(103)를 회전하여 롤러 조절 부재(103)의 길이를 조절하며, 이에 따라 외부 부재(105)의 일단에 연결된 성형 롤러의 형태와 상하 성형 롤러들(101a, 101b) 사이의 간격을 조절하게 된다. Accordingly, the length of the roller adjusting member 103 is adjusted by rotating each inner member 103 by one or a plurality of motors, and thus the shape of the forming roller connected to one end of the outer member 105 and the upper and lower forming rollers. The distance between the two (101a, 101b) is to be adjusted.
도 5 및 도 6으로 돌아가서, 롤러 조절 부재(103)의 성형 롤러(101a, 101b)에 고정되는 단부, 즉 도면의 실시예에서 외부 부재(105)의 하단 단부에는 회동가능한 롤러 가이드(109)가 구비될 수 있는데, 롤러 가이드(109)에는 성형 롤러(101a, 101b)가 맞물리는 반원보다 큰 원호형 홈(109a)이 제공된다. 두 개의 수평으로 놓인 성형 롤러(101a, 101b)에 대하여 다수의 롤러 조절 부재(103)가 수직으로 배열되므로, 성형 롤러(101a, 101b)가 맞물리는 회동가능한 롤러 가이드(109)는 롤러 조절 부재(103)의 길이를 조절하여 성형 롤러(101a, 101b)의 곡률을 변경할 때 성형 롤러가 자연스럽게 휘어질 수 있도록 한다. 5 and 6, a rotatable roller guide 109 is provided at an end fixed to the forming rollers 101a and 101b of the roller adjusting member 103, that is, at the lower end of the outer member 105 in the embodiment of the figure. The roller guide 109 is provided with an arcuate groove 109a which is larger than the semicircle in which the forming rollers 101a and 101b are engaged. Since the plurality of roller adjusting members 103 are vertically arranged with respect to the two horizontally placed forming rollers 101a and 101b, the rotatable roller guide 109 to which the forming rollers 101a and 101b are engaged has a roller adjusting member ( Adjusting the length of the 103 to change the curvature of the forming roller (101a, 101b) so that the forming roller can bend naturally.
도 8 및 도 9는 상기 성형 롤러의 구성예를 도시하고 있다. 도시된 바와 같이 성형 롤러(101a)는 다수의 강선을 여러 겹으로 감아 형성될 수 있다. 이때 성형 롤러(101a)의 최 외곽 면에 감긴 강선은 판재와 접촉하는 바깥쪽 면(111)이 평평하도록 연삭가공되는 것이 바람직하다. 이와 같이 성형 롤러(101a)가 판재와 접촉하는 면(111)을 평평하게 형성함으로써 국부적인 딤플이나 주름이 형성되는 것을 방지할 수 있다. 달리, 성형 롤러(101a)의 최 외곽 면에 단면이 타원형인 강선을 감아 판재와 접촉하는 면(111a)을 평평하게 형성할 수도 있다. 도면에는 하나의 성형 롤러(101a)에 대하여 도시하였으나, 나머지 성형 롤러(101b)도 동일하게 구성된다. 8 and 9 show examples of the configuration of the forming roller. As shown, the forming roller 101a may be formed by winding a plurality of steel wires in multiple layers. At this time, the steel wire wound on the outermost surface of the forming roller (101a) is preferably processed to be ground so that the outer surface 111 in contact with the plate. Thus, by forming the surface 111 which the forming roller 101a contacts the board | plate material flat, it can prevent that local dimples and wrinkles are formed. Alternatively, the outer surface of the forming roller 101a may be wound with a steel wire having an elliptical cross section to form a flat surface 111a in contact with the sheet material. Although one molding roller 101a is shown in the figure, the other molding roller 101b is also configured in the same way.
성형 롤러(101a, 101b)는 또한 도 4에 도시된 바와 같이 양단이 롤러 회전 모터(113)에 연결되어 자동 회전하도록 구성될 수 있는데, 이 경우 판재(102)는 도 10에 도시된 바와 같이 상하 성형 롤러(101a, 101b) 사이에 맞물린 채 성형 롤러들(101a, 101b)의 회전에 의해 밀려나오면서 성형된다. 이때 판재(102)의 성형 형상은 두 개의 성형 롤러(101a, 101b)의 형태 및 그 사이의 간격에 의해 결정되며, 이러한 성형 롤러(101a, 101b)의 형태와 간격은 목적 형상에 따라 상기한 바와 같이 롤러 조절 부재(103)에 의해 조절된다. 달리, 롤러 회전 모터(113)는 상부 성형 롤러(101a) 또는 하부 성형 롤러(101b) 하나에만 연결되어 구동력을 전달 할 수도 있으며, 또는 롤러 회전 모터가 생략될 수도 있다. 롤러 회전 모터가 없는 경우에는 도 11에 도시된 바와 같이 상하 성형 롤러(101a, 101b) 사이에 판재(102)를 삽입하고 반대편에서 잡아당겨 성형하게 된다. 판재(102)의 성형 형상은 역시 두 개의 성형 롤러(101a, 101b)의 형태 및 그 사이의 간격에 의해 결정되며, 이는 롤러 조절 부재(103)에 의해 조절된다. The forming rollers 101a and 101b may also be configured to automatically rotate when both ends are connected to the roller rotating motor 113 as shown in FIG. 4, in which case the plate 102 is up and down as shown in FIG. 10. It is molded while being pushed out by the rotation of the forming rollers 101a and 101b while being engaged between the forming rollers 101a and 101b. At this time, the molding shape of the plate member 102 is determined by the shape of the two forming rollers 101a and 101b and the gap therebetween, and the shape and spacing of the forming rollers 101a and 101b are as described above according to the desired shape. It is adjusted by the roller adjusting member 103 as well. Alternatively, the roller rotating motor 113 may be connected to only the upper forming roller 101a or the lower forming roller 101b to transmit driving force, or the roller rotating motor may be omitted. In the absence of a roller rotating motor, as shown in FIG. 11, the plate 102 is inserted between the upper and lower forming rollers 101a and 101b and pulled from the opposite side to be molded. The forming shape of the plate material 102 is also determined by the form of the two forming rollers 101a and 101b and the gap therebetween, which is controlled by the roller adjusting member 103.
이와 같이, 유연한 성형 롤러의 형태 및 간격을 조절하여 판재를 성형함으로써, 목적 형상의 변경에 따라 간단히 성형 형상을 수정할 수 있으며, 연속적인 성형면을 제공하는 상하 두 개의 성형 롤러(101a, 101b)가 판재(102)에 맞물려 성형하므로 딤플이나 주름이 형성될 염려가 없다. In this way, by forming the plate by adjusting the shape and spacing of the flexible forming roller, it is possible to simply modify the forming shape in accordance with the change of the target shape, the two upper and lower forming rollers (101a, 101b) to provide a continuous forming surface Since it is engaged with the sheet material 102, there is no fear of dimples or wrinkles.
이하에서는, 상기와 같이 구성되는 본 발명에 따른 무금형 판재 성형 장치를 사용하여 판재를 성형하는 방법을 구체적인 성형예를 통하여 살펴본다. Hereinafter, a method of molding a plate using the die-less plate forming apparatus according to the present invention configured as described above will be described through a specific forming example.
본 발명에 따른 판재 성형 장치(100)에서는 상하로 대응되는 두 개의 성형 롤러(101a, 101b)의 곡률 및 그 사이의 간격에 의해 판재(102)의 성형 형상이 결정된다. 즉, 두 개의 성형 롤러(101a, 101b) 사이의 간격이 좁은 부위에서는 그 사이에 맞물려 성형되는 판재의 길이변화량이 크고, 두 개의 성형 롤러(101a, 101b) 사이의 간격이 넓은 부위에서는 성형되는 판재의 길이변화량이 적은 원리에 의하여 판재(102)의 곡면이 성형된다. In the sheet metal forming apparatus 100 according to the present invention, the molding shape of the plate 102 is determined by the curvature of the two forming rollers 101a and 101b corresponding to the top and bottom and the gap therebetween. That is, the length change amount of the plate | board material which is engaged and formed between the two shaping rollers 101a and 101b is large, and the board | plate material shape | molded in the site | part where the space | interval between two shaping rollers 101a and 101b is large. The curved surface of the plate member 102 is molded by the principle of the small amount of length change.
예컨대, 도 12와 같이 두 개의 성형 롤러(101a, 101b)의 간격이 중간 부분(c)에선 좁게 형성되고 가장자리(a 및 e)에서 넓게 형성되어 전체적으로 (a = e) > (b = d) > c의 간격으로 배열되는 경우, 도 13과 같이 판재(102)의 길이변화량은 중간 부분(c')이 크고 가장자리(a' 및 e')는 적어 전체적으로 c' > (b' = d') > (a' = e') 이 되며, 따라서 볼록형(Convex type)으로 성형된다. For example, as shown in FIG. 12, the spacing between the two forming rollers 101a and 101b is narrow at the middle portion c and wide at the edges a and e so that (a = e)> (b = d)> When arranged at intervals of c, as shown in FIG. 13, the length change amount of the plate 102 has a large middle portion c 'and a small number of edges a' and e ', so that c'> (b '= d')> (a '= e'), thus forming a convex type.
또한, 도 14와 같이 두 개의 성형 롤러(101a, 101b)의 간격이 중간 부분(c)에선 넓게 형성되고 가장자리(a 및 e)에서 좁게 형성되어 전체적으로 c > (b = d) > (a = e)의 간격으로 배열되는 경우, 도 15와 같이 판재(102)의 길이변화량은 중간 부분(c')이 적고 가장자리(a' 및 e')는 커서 전체적으로 (a' = e') > (b' = d') > c' 이 되며, 따라서 안장형(Saddle type)으로 성형된다. In addition, as shown in FIG. 14, the spacing between the two forming rollers 101a and 101b is wide at the middle portion c and narrow at the edges a and e so that c> (b = d)> (a = e) as a whole. When arranged at intervals of), as shown in FIG. 15, the length variation of the plate 102 is small in the middle portion c 'and the edges a' and e 'are large so that (a' = e ')> (b') as a whole. = d ')> c', thus forming a saddle type.
또 다른 예로, 도 16과 같이 두 개의 성형 롤러(101a, 101b)의 간격이 한 방향으로 점점 넓어져 전체적으로 e > d > c > b > a의 간격으로 배열되는 경우, 도 17과 같이 판재(102)의 길이변화량은 a' > b' > c' > d' > e' 로 비틀린형(Twist type)으로 성형된다. As another example, when the distance between the two forming rollers 101a and 101b is gradually widened in one direction as shown in FIG. 16, and is generally arranged at an interval of e> d> c> b> a, the plate 102 as shown in FIG. 17. ), The length change amount is formed into a twist type with a '> b'> c '> d'> e '.
이와 같이, 롤러 조절 부재(103)의 길이 조절에 의해 성형 롤러(101a, 101b)의 곡률 및 간격을 여러 모양으로 조절할 수 있으며, 이에 따라 판재(102)를 다양한 형태로 성형할 수 있다. 따라서, 본 발명의 판재 성형 장치는 다품종 소량 판재 성형에 적합할 뿐 아니라, 판재의 가장자리까지 성형이 가능하고, 판재의 길이에 제한이 없이 성형이 가능하다.As such, the curvature and the spacing of the forming rollers 101a and 101b may be adjusted to various shapes by adjusting the length of the roller adjusting member 103, and thus, the plate 102 may be molded into various shapes. Therefore, the sheet forming apparatus of the present invention is not only suitable for forming a small quantity of various kinds of sheets, but also can be molded to the edge of the sheet, and the sheet can be formed without limitation on the length of the sheet.
