멜라민시이트 성형용 니켈박판의 가압방법 및 그 장치 {Method and apparatus for pressing nickel base thin film for forming melamine sheet}Method for pressing nickel sheet for forming melamine sheet and apparatus therefor {Method and apparatus for pressing nickel base thin film for forming melamine sheet}

본 발명은 실내 장식용 판재로 많이 쓰이는 멜라민시이트의 표면에 요철무늬를 성형키 위해 니켈박판을 이용하여 멜라민수지를 가압대로 열압착할 시에 열전도판과 성형용 니켈박판의 밀착성을 높혀 성형효과를 높게 하고 변형을 최소화한 멜라민시이트 성형용 니켈박판의 가압방법 및 그 장치에 관한 것이다.The present invention is to increase the molding effect by increasing the adhesion of the heat conduction plate and the nickel plate for molding when hot-pressing the melamine resin using a pressurized nickel plate to form the uneven pattern on the surface of the melamine sheet, which is frequently used as interior decoration sheet. The present invention relates to a pressurizing method and apparatus for nickel sheet for melamine sheet molding which minimizes deformation.

멜라민수지는 그 재질의 경고성 등으로 인하여 실내 장식판 등으로 많이 사용되고 있고 장식효과를 높이기 위해 시이트의 표면에 무늬가 요철로 형성된 성형용 가압판을 가열 가압하여 멜라민시이트에 요철무늬를 형성하므로서 제품의 고급화를 이루고 있고, 그 가압대에 사용되는 성형판으로는 평판상의 스테인레스판에 무늬가 도안된 필름을 부착하여 그 필름을 이용하여 무늬 외 부분을 부식액에 의해 부식처리 하므로서 부식된 부분과 부식되지 않은 부분의 높이 차이에 의해 요철무늬가 형성되게 하여 이를 성형판으로 이용하기도 하고, 본 발명의 출원인이 발명한 바 있는(특허출원 제2008-91919호) 니켈박판 즉, 실물견본에 액상 실리콘을 도포하여 응고시킨 후 이를 분리하여 실물과 동일한 요철무늬가 형성된 실리콘판의 표면에 경도가 높은 니켈을 도금시켜 다시 도금형성된 니켈판과 실리콘판을 분리하여 분리된 니켈박판을 성형판으로 사용하고 있다.Melamine resin is widely used for interior decoration boards due to the warning of its material, and in order to enhance the decorative effect, the pressurizing plate formed with irregularities on the surface of the sheet is heated and pressed to form irregularities on the melamine sheet. As the forming plate used for the presser, the patterned pattern is attached to the plate-shaped stainless plate, and the outside part of the pattern is corroded by the corrosion solution using the film. The uneven pattern is formed by the height difference of the metal plate, which may be used as a molding plate, and the solidification of the nickel plate, that is, the real sample, by the applicant of the present invention (Patent Application No. 2008-91919). After removing it, the high hardness on the surface of the silicon plate The plating has to use a nickel thin plate separated by separating the back plate and a nickel plating formed in the silicon plate with a mold plate.

그러나 스테인레스성형판은 그 요철무늬를 전기한 바와 같이 필름에 도안된 무늬를 부식액에 의해 부식 형성하는 것이므로 섬세하고 세밀한 무늬와 요철부의 돌출부가 완만한 곡선상으로 이루어진 것을 표현할 수 없는 한계가 있고, 이를 보완키 위해 실리콘에 의해 견본의 본을 뜨고 그 표면에 니켈을 도금처리한 니켈박판을 형성하므로서 섬세한 요철무늬나 곡선상의 돌출부 형성은 가능하나, 압력을 가하는 성형용 가압판의 특성상 3~5mm 이상의 두께를 요구하고 있으나 니켈의 특성상 그 두께에 따른 원가상승의 문제와 평탄도와 정밀성이 저하되는 문제가 있어 니켈판을 0.5~1.5mm 정도의 얇은 두께인 박판으로 형성하여 이를 별도의 가볍고 열전도가 좋은 열전도용 알미늄판에 결합시켜 성형판으로 사용하고 있다.However, since the stainless molding plate corrodes the pattern drawn on the film by the corrosive solution as described above, the concave-convex pattern has a limitation in that it cannot express that the fine and fine pattern and the protrusion of the concave-convex portion are formed in a gentle curve shape. For the purpose of supplementing the pattern of specimen by silicon and forming nickel plated nickel plated on the surface, it is possible to form a fine uneven pattern or curved protrusion, but the thickness of 3 ~ 5mm or more is possible due to the characteristics of the pressure plate. However, due to the characteristics of nickel, there is a problem of cost increase and flatness and precision deterioration according to the thickness of the nickel, and thus the nickel plate is formed into a thin plate having a thickness of about 0.5 to 1.5 mm, which is a separate light and good thermal conductivity aluminum. It is bonded to a plate and used as a molding plate.

중량의 경량화와 높은 열전도율을 유지하면서도 성형면의 높은 경도를 위해 니켈박판과 알미늄판을 결합시켜 사용한 경우, 높은 온도의 가열이 필요한 작업의 특성상 니켈박판과 알미늄판의 열팽창율이 많이 다르기 때문에 서로의 다른 팽창율 때문에 가압판 자체가 변형될 수 있기 때문에 니켈박판과 알미늄판의 전면을 완전 접착할 수 없는 문제가 있다.In the case of using a combination of thin nickel plate and aluminum plate for high hardness of the molding surface while maintaining weight reduction and high thermal conductivity, the thermal expansion coefficient of the nickel plate and aluminum plate is very different due to the characteristics of the work requiring high temperature heating. Since the pressure plate itself may be deformed due to different expansion rates, there is a problem in that the front surface of the nickel thin plate and the aluminum plate cannot be completely bonded.

그러므로 도 1의 도시와 같이 열선(1)에 내장된 상하열판(2)(2')의 표면에 결합된 가압대(3)의 열전도용 알미늄판(4)과 니켈박판(5)의 일부분만을 고정하여 프레스기에 결합 사용하여 열로 인한 팽창에 대처하였다. 그 니켈박판이 결합된 하부성형판으로 사용되어 이에 의해 멜라민시이트의 한쪽면 만을 성형할 때는 별문제가 없으나 도 1의 도시와 같이 양쪽면을 동시에 성형할 경우에는 실린더(6)에 의해 상하 승강되는 상부에도 성형용 가압대(3)를 장착하여야 되므로 알미늄판의 저면에 결합된 니켈박판이 전면에 접착되지 않은 관계로 보통 2800X1400mm 크기의 니켈박판(5) 중앙부가 비교적 얇은 두께로 인하여 그 하중에 의해 밑으로 쳐지게 되어 니켈박판(5)이 열전도용 알미늄판(4)으로부터 떨어져 간극이 발생하게 프레스기의 상하운동시 마다 변형이 발생될 뿐 아니라 열전도판으로부터의 분리로 인해 열전도율이 떨어지는 문제가 있어 작업성이 떨어지는 문제가 발생하였다.Therefore, as shown in FIG. 1, only a part of the aluminum plate 4 and the nickel thin plate 5 for heat conduction of the presser 3 coupled to the surface of the upper and lower heating plates 2 and 2 ′ embedded in the heating wire 1 are illustrated. Fixed and coped with the press to cope with thermal expansion. The nickel plate is used as a lower molding plate to be bonded, whereby there is no problem when forming only one side of the melamine sheet, but when forming both sides at the same time as shown in FIG. Since the pressing plate for molding (3) should be installed, the center of the nickel thin plate (5) of 2800 × 1400 mm size is relatively thin, so that the nickel thin plate bonded to the bottom of the aluminum plate is not adhered to the front surface. As the nickel plate 5 is separated from the aluminum plate 4 for heat conduction and the gap is generated, deformation occurs every time the press machine moves up and down, and there is a problem that thermal conductivity falls due to separation from the heat conduction plate. This falling problem occurred.

이와 같은 문제점을 제거함에 본 발명의 목적이 있다.It is an object of the present invention to eliminate this problem.

본 발명은 전기한 바와 같은 문제점을 제거코저, 가열과 가압이 동시에 이루어지는 프레스기의 가압대의 알미늄판에 니켈박판을 부착함에 있어서, 알미늄판과 니켈박판의 사이에 실리콘테이프를 이용하여 밀폐형성된 공간인 진공조를 형성한 후 이 진공조와 관통되어 연결된 진공흡입펌프의 진공 흡입력에 의한 진공력으로 니켈박판과 알미늄판의 피가압물 가압부분의 표면을 완전밀착시켜 밀착력을 강화하면서도 열변형에도 대처되게 열압착할 수 있게 한 가압방법과, 그 방법을 수행키 위해 가열이 가능한 프레스기 가압대의 알미늄판과 니켈박판을 지지수단에 의해 결합하되 그 알미늄판과 니켈박판 사이에 표면의 4변을 따라 실리콘테이프를 밀착시키고 그 실리콘 테이프의 내측공간으로 노출 형성된 흡입공을 별도의 진공흡착펌프와 연결 구성한 멜라민시이트 성형용 니켈박판의 가압장치를 제공되게 한 것이다.The present invention eliminates the problems as described above, in attaching a nickel thin plate to the aluminum plate of the press of the press machine, which simultaneously performs heating and pressurization, a vacuum formed in a sealed space using a silicon tape between the aluminum plate and the nickel thin plate. After the tank is formed, the surface of the pressurized part of the nickel plate and aluminum plate pressurized by the vacuum suction power of the vacuum suction pump connected to the vacuum tank is tightly adhered to enhance the adhesion and thermally press to cope with thermal deformation. The method of pressurization, which is made possible, and the aluminum plate and nickel plate of the press-pressing press which can be heated to carry out the method are joined by a supporting means, and the silicon tape is closely adhered along the four sides of the surface between the aluminum plate and the nickel plate. And connect the suction hole exposed to the inner space of the silicone tape with a separate vacuum suction pump It is intended to provide a pressurization device for forming a thin sheet of melamine sheet.

본 발명의 멜라민시이트 성형용 니켈박판의 가압방법 및 그 장치는 열전도판인 알미늄판과 요철 성형용 니켈박판을 완전고정하지 아니하고 필요시에만 진공흡입력에 의해 완전 밀착고정되게 하므로서, 열전도율이 균일하여 성형작업성이 우수하면서도 니켈박판이 자중에 의해 하부로 늘어지거나 처질우려가 없어 일정한 성형이 가능하고 열팽창성이 다른 두 물질의 결합이더라도 완전 고정이 아니고 진공흡착과 분리의 반복으로 서로 다른 물질에 열변형의 영향을 미치지 아니하므로서 열팽창 차이로 인한 뒤틀림 등이 발생하지 않는 효과가 있는 것이다.The pressurizing method and apparatus for the melamine sheet molding nickel thin plate according to the present invention do not completely fix the aluminum plate which is the heat conductive plate and the nickel thin plate for the uneven forming, and are only completely fixed by vacuum suction input when necessary, so that the thermal conductivity is uniformly formed. It is excellent in workability, and it is possible to make a certain shape because nickel plate does not hang down or fall down due to its own weight. Even though the combination of two materials with different thermal expansion properties is not fixed, it is not completely fixed and heat deformation to different materials by repeated vacuum absorption and separation. Since it does not affect the effect of distortion due to the difference in thermal expansion is to occur.

이하, 본 발명의 멜라민시이트 성형용 니켈박판의 가압방법 및 그 장치를 실시예에 의하여 상세히 설명한다.Hereinafter, the pressing method and apparatus of the nickel thin plate for melamine sheet molding of the present invention will be described in detail with reference to Examples.

The connection state with the vacuum suction pump is shown.

열선(11)(11')이 내장되어 가열이 가능한 상하열판(12)(12')에 각기 무늬성형용 가압대(13)(13')를 결합하여 유압실린더(14)(14')에 의해 상하 승강되면서 피 가압물을 가열 가압하는 가압장치에 있어서,The heating wires 11 and 11 'are combined with the upper and lower heating plates 12 and 12', which are capable of heating, respectively, and the hydraulic pressure cylinders 14 and 14 'are coupled to the pressing molds 13 and 13'. In the pressurizing device for heating and pressurizing the object to be pressurized while moving up and down by,

그 무늬성형용 가압대(13)(13')를 열전도용 알미늄판(15)과 무늬성형용 니켈박판(16)을 지지프레임(17)에 의해 결합하되,The pattern forming presses 13 and 13 'are combined with the aluminum plate 15 for heat conduction and the nickel plate 16 for pattern forming by a support frame 17,

이와 같이 된 본 발명의 가압장치에 의한 가압방법을 그 공정별로 상세히 설명한다.The pressurization method by the pressurizing device of the present invention as described above will be described in detail for each step.

무늬성형용 가압대(13)(13')를 본원발명에 의한 즉, 열전도용 알미늄판(15)과 니켈박판(16)의 사이에 표면의 4변을 따라 실리콘 테이프(18)를 끼워 붙인 후, 이를 지지프레임(17)과 고정나사(22)(22') 등으로 결합하게 되면 실리콘 테이프(18)의 두께 만큼 알미늄판(15)과 니켈박판(16)의 사이에 이격 밀폐된 공간부(19)가 발생하므로 필요시에 그 공간부(19) 내측으로 관통 형성된 흡입공(20)과 연결된 진공흡입펌프(21)를 작동시켜 진공흡입케 되면 전기한 공간부(19)에 진공력이 발생된다.After attaching the silicone tape 18 along the four sides of the pattern forming pressure band 13, 13 'according to the present invention, that is, between the aluminum plate 15 for heat conduction and the nickel thin plate 16, When it is combined with the support frame 17 and the fixing screws 22, 22 ', etc., the spaced portion spaced between the aluminum plate 15 and the nickel thin plate 16 by the thickness of the silicon tape 18 ( 19 is generated, if necessary, when the vacuum suction pump 21 connected to the suction hole 20 penetrated into the space portion 19 is operated to vacuum suction, a vacuum force is generated in the space portion 19 that was previously described. do.

그 진공력에 의해 니켈박판(16)이 공간부(19) 측으로 흡입되면서 공간부(19)가 소멸됨과 동시에 알미늄판(15)과 니켈박판(16)의 피가압물의 가압부분이 완전 밀착될 수 있는 것이다.Due to the vacuum force, the nickel thin plate 16 is sucked into the space 19, and the space 19 is extinguished. At the same time, the pressurized portion of the pressurized product of the aluminum plate 15 and the nickel thin plate 16 can be completely in contact with each other. It is.

이와 같이 진공력에 의해 알미늄판(15)과 니켈박판(16)의 완전밀착 가능한 가압대(13)(13')를 이용하여 피가공물인 멜라민시이트(23)의 표면에 요철무늬를 성형할 시에는 상하가압대(13)(13')의 사이에 성형코저 하는 멜라민시이트(23)를 놓고 열선(11)(11')을 작동시켜 열판(12)(12')을 가열(160℃~200℃)한 상태에서 진공흡입펌프(21)에 의해 알미늄판(15)과 니켈박판(16)을 밀착시킨 후 유압실린더(14)(14')에 의해 상부 가압대(13)를 하강시키면 열전도율이 좋은 알미늄판(15)에 의해 니켈박판(16)에 열이 고르게 전달된 상태에서 상하가압대(13)(13')에 의해 멜라민시이트(23)의 상하면에 압력을 가하게 되어 멜라민시이트(23)의 상하면에 섬세한 요철무늬를 성형할 수 있는 것이다.In this way, when the uneven pattern is formed on the surface of the melamine sheet 23, which is the workpiece, by using the pressure bands 13 and 13 'that the aluminum plate 15 and the nickel thin plate 16 can be completely adhered to each other by vacuum force. The heating plate 11, 11 'is heated by placing a melamine sheet 23 formed between the upper and lower pressing bars 13 and 13' and heating the hot plates 12 and 12 '(160 ° C to 200 ° C). In the state in which the aluminum plate 15 and the nickel thin plate 16 are brought into close contact with each other by the vacuum suction pump 21, and then the upper press table 13 is lowered by the hydraulic cylinders 14 and 14 '. In the state in which heat is evenly transferred to the nickel thin plate 16 by the good aluminum plate 15, the upper and lower surfaces of the melamine sheet 23 are pressed by the upper and lower pressing bars 13 and 13 ′, and the melamine sheet 23 is applied. Delicate irregular patterns can be molded on the upper and lower surfaces.

이때 알미늄판(15)과 니켈박판(16)은 피가압물을 가압하는 평면부분이 전면에 걸쳐 완전 밀착되므로서 열전도율이 균일하여 가공성이 우수하면서도 니켈박판(16)이 자중에 의해 하부로 늘어지거나 처질우려가 없어 일정한 성형이 가능하고 열팽창성이 다른 두 물질의 결합이더라도 완전 고정이 아니고 진공흡착과 분리의 반복으로 서로 다른 물질에 열변형의 영향을 미치지 아니하므로서 열팽창 차이로 인한 뒤틀림 등이 발생하지 않는 효과가 있는 것이다.At this time, the aluminum plate 15 and the nickel thin plate 16 are in close contact with the flat portion pressurizing the material to be pressurized, so that the thermal conductivity is uniform, so that the nickel plate 16 is stretched downward due to its own weight. There is no fear of drooping, and it is possible to make a certain mold. Even if the combination of two materials with different thermal expansion properties is not completely fixed, the vacuum suction and separation do not affect the different materials due to the thermal deformation, and thus no distortion occurs due to thermal expansion difference. It does not work.
