Abstract

본 발명은 비철금속 박판 가공방법 및 박판가공용 지그와 이들에 의하여 가공된 가공물에 관한 것이다.The present invention relates to a nonferrous metal sheet processing method and sheet processing jig and the workpiece processed by them.

비철금속제 박판을 1~2mm 두께로 가공함에 있어서는 자석식 지그를 적용할 수 없기 때문에 원통체로된 연마롤러 두개 사이를 통과시켜 양면을 동시에 가공하는 방식이 종래의 통상적인 방법이나, 이와 같은 종래의 가공방법은 휨 등에 의하여 40% 이상의 많은 불량률이 발생하게 됨으로서, 막대한 자원의 낭비와 생산원가가 고가로 되는 등 비경제적이며 비생산적인 문제점이 있었다.In the case of processing non-ferrous metal sheet with a thickness of 1 ~ 2mm, the magnetic jig cannot be applied, so the method of simultaneously machining both sides by passing between two cylindrical polishing rollers is the conventional method, or such conventional processing method. Since a large number of defects are generated by more than 40% due to warpage, there is an uneconomical and unproductive problem such as wasteful resources and high production costs.

본 발명은 4~5mm 판재로된 비철금속재 판을 1차 휨이나 변형없이 기준 평활면을 갖도록 가공함에 있어 에어 흡착구가 수개 장착된 지그를 선반의 척에 고정시킨 상태에서 한쪽면을 가공하여 기준면을 얻은 다음 정반형 에어 흡입식 지그에 가공면을 부착시키고 다시 반대면을 가공하여 양면이 평활한 2~3mm두께의 비철금속제 박판을 얻을 수 있도록 한 것이다.In the present invention, in processing a non-ferrous metal plate made of 4-5mm plate to have a standard smooth surface without primary bending or deformation, one side is processed by fixing one side of the jig equipped with several air suction holes to the chuck of the lathe and the reference surface. After obtaining, the surface was attached to the surface-type air suction jig and the reverse side was processed to obtain a non-ferrous metal sheet having a thickness of 2 to 3 mm on both sides.

Description

비철금속 박판 가공방법 및 박판가공용 지그와 이들에 의하여 가공된 가공물{Treatment method of nonferrous sheet metal and jig for treatment of sheet metal and treatment material treated by them}Processing method of nonferrous sheet metal and jig for treatment of sheet metal and treatment material treated by them}

본 발명은 비철금속 박판 가공방법 및 박판가공용 지그와 이들에 의하여 가공된 가공물에 관한 것으로 상세하게는 알루미늄 또는 두랄루민 기타 동판 등과 같은 비금속제 박판을 공작기계에 의하여 가공함에 있어 1차 가공시 휨과 불량의 발생없이 양면을 수평가공하여 2차 가공에서 원하는 극미세 평활도를 얻어 PCB기판 등 각종 첨단 반도체 부품 및 가스 배관상의 판막 등 고정밀도를 요하는 각종 산업 분야의 부품재를 가공 하기에 적당하도록 한 것이다.The present invention relates to a non-ferrous metal sheet processing method and a sheet processing jig and the workpiece processed by them, and more specifically, in the processing of non-metallic thin plates such as aluminum, duralumin or other copper plates by machine tools, Both sides are horizontally processed without any occurrence to obtain the ultra-fine smoothness desired in the secondary processing, so that they are suitable for processing various high-tech semiconductor parts such as PCB boards and components in various industrial fields such as valves on gas pipes.

밀링, 연삭기 등 공작기계에서 철금속 박판을 가공하는 방법은 자석 부착식 지그를 이용하여 가공물을 견고히 부착시킨 상태에서 일면을 가공한 후 반대 면을 가공하는 방법에 의하여 박판을 정밀하게 가공하는 것이 가능하나, 반도체 부품 PCB 기판 둘레 테두리 몰딩이나 가스 배관 라인에 적용되는 판막 등은 금속제가 아니 알루미늄 혹은 두랄루민과 같은 비철금속제 박판이 주로 사용된다.As for the method of processing ferrous metal sheet in machine tools such as milling and grinding machines, it is possible to precisely process the thin plate by processing the one side after the workpiece is firmly attached by using magnetic attachment jig. However, a thin plate made of a non-ferrous metal such as aluminum or duralumin is mainly used for a semiconductor component PCB substrate circumferential molding or a valve applied to a gas pipe line.

이와 같은 비철금속제 박판을 1~2mm 두께로 가공함에 있어서는 상기에서와 같은 자석식 지그를 적용할 수 없기 때문에 원통체로된 연마롤러 두개 사이를 통과시켜 양면을 동시에 가공하는 방식이 종래의 통상적인 방법이나, 이와 같은 종래의 가공방법은 휨 등에 의하여 40% 이상의 많은 불량률이 발생함에도 별다른 가공방법이 없었기 때문에 대안없이 가공하게 됨으로서, 막대한 자원의 낭비와 생산원가가 고가로 되는 등 비경제적이며 비생산적인 문제점이 있었다.In the case of processing such a non-ferrous metal sheet to a thickness of 1 to 2 mm, the magnetic jig as described above cannot be applied, and a method of simultaneously machining both sides by passing between two cylindrical polishing rollers is a conventional method. Such a conventional processing method has no special processing method even though a large defect rate of more than 40% is generated due to warpage, so that the processing without alternatives, there is an uneconomical and unproductive problem such as waste of resources and high production costs.

본 발명은 이와 같은 제결점을 감안 해결하기 위하여 안출한 것으로서, 제강업체에서 4~5mm 판재로 공급되는 비철금속재 판을 1차 휨이나 변형없이 기준 평활면을 갖도록 가공함에 있어 에어 흡착구가 수개 장착된 지그를 선반의 척에 고정시킨 상태에서 한쪽면을 가공하여 기준면을 얻은 다음 정반형 에어 흡입식 지그에가공면을 부착시키고 다시 반대면을 가공하여 양면이 평활한 2~3mm두께의 비철금속제 박판을 얻을 수 있도록 한 것이다.The present invention has been made in view of the above-mentioned drawbacks, the number of air suction holes in the non-ferrous metal sheet supplied by the steelmaker 4-5 mm sheet to provide a standard smooth surface without the first bending or deformation installed With the fixed jig fixed on the chuck of the lathe, process one side to get the reference surface, then attach the processing surface to the surface-type air suction jig, and then process the opposite side again to make a non-ferrous metal sheet of 2 ~ 3mm thickness that is smooth on both sides. To get it.

상기 목적을 실현하기 위하여 4~5mm 두께의 비철금속제 원판재(1)를 가공물의 형태에 따라 원형 또는 4각의 형태로 절취 하여 가공판재(2)를 형성하는 제 1공정; 상기 가공판재(2)를 선반의 척, 또는 밀링 다이에 물려 고정시킨 에어흡착 고정지그(3a)에 부착 시킨다음 휨이 발생되지 않는 견고한 고정 상태에서 일면을 1~1.5mm절삭 가공하여 기준면을 만드는 제 2공정; 일면이 가공된 가공판재(2)를 다른 선반, 밀링에 고정시킨 정반형 에어흡착 고정다이스(3b)로 옮겨 가공된 면을 부착시킨 다음 가공되지 않은 반대면을 1~1.5mm절삭 가공하여 2~3mm 두께의 1차가공이 완성된 가공판재(2)를 얻는 제 3공정; CNC 공작기계에 의한 2차 가공으로 양면을 초미세 절삭 가공하는 제 4공정에 의하여 비철금속제 박판가공을 완성하게 된다.In order to achieve the above object, the first step of forming the processed plate member (2) by cutting the non-ferrous metal plate member (1) of 4 ~ 5mm thickness in the form of a circle or a square according to the shape of the workpiece; After attaching the processed plate material 2 to the air adsorption fixing jig 3a fixed by being bitten by a chuck or a milling die of a lathe, the surface is made by cutting 1 to 1.5 mm from one side in a rigid fixed state where bending does not occur. Second process; Transfer the processed plate material (2) on one side to the surface plate-type air adsorption fixed die (3b) fixed to another lathe and milling, attach the processed surface, and cut the unprocessed opposite surface by 1 ~ 1.5mm. A third step of obtaining a processed plate material 2 on which primary processing of 3 mm thickness is completed; In the second process by the CNC machine tool, the fourth process of ultra-fine cutting on both sides is completed to finish the non-ferrous metal sheet processing.

이상의 각 공정에 의한 가공에 있어 비철금속제 박판의 고정수단이 핵심요소로서, 이를 실현하기 위한 상기 에어흡착 고정지그(3a)는 직육면체의 지그틀체(4)에 에어 파이프(5)와 고무로된 나팔형의 에어흡착구(6)를 연결 장착할 수 있는 취부홈(7)을 형성하여 이들을 장착 설치하고, 일측면 외측으로는 진공펌프와 연결되게 에어 파이프(5)를 연결하되, 흡입밸브(9a)와 에어 공급밸브(9b) 및 압력 게이지(10)가 설치된 에어 조절장치(8)를 장착 설치하여 구성된 것이다.In the processing by the above processes, the fixing means of the nonferrous metal sheet is a key element, and the air adsorption fixing jig 3a for realizing this is an air pipe 5 and a rubber trumpet in the jig frame 4 of the rectangular parallelepiped. Form an installation groove (7) for connecting and mounting the air suction port (6) of the type and install them, and connect the air pipe (5) to be connected to the vacuum pump on one side outside, the intake valve (9a) ) And an air regulator 8 installed with an air supply valve 9b and a pressure gauge 10.

이와 같은 일련의 공정과 장치에 의하여 가공되는 본 발명은 에어흡착 고정지그(3a)를 선반의 척에 고정시킨 상태에서 원판재(1)로 부터 절취한 가공판재(2)를 지그에 붙이고, 에어 공급밸브(9b)를 차단한 상태에서 흡입밸브(9a)를 개방하게 되면 각 에어흡착구(6)들이 가공판재(2)를 진공력으로 빨아당겨 에어흡착 고정지그(3a)의 부착면에 가공판재(2)를 견고히 부착시키는 작용을 하게 되므로 선반이나 밀링 가공시 휨이나 뒤틀림 등의 변형의 문제가 근본적으로 해결되는 것이다.The present invention processed by such a series of processes and apparatus is attached to the jig to attach the processed plate material (2) cut from the original material (1) in a state where the air adsorption fixing jig (3a) is fixed to the chuck of the shelf, When the intake valve 9a is opened while the supply valve 9b is shut off, each air suction port 6 sucks the processed plate material 2 with a vacuum force and processes it on the attachment surface of the air suction fixing jig 3a. Since the plate 2 is firmly attached, the problem of deformation such as bending or warping during lathe or milling is fundamentally solved.

가공이 완료되고 난 후에는 흡입밸브(9a)를 잠그고, 에어 공급밸브(9b)를 개방하여 에어를 공급하게 되므로서, 에어흡착 고정지그(3a)의 부착면에 고정되어 있던 가공판재(2)를 용이하게 분리시킬 수 있게되는 것이다.After the processing is completed, the suction valve 9a is closed, and the air supply valve 9b is opened to supply air, thereby processing plate member 2 fixed to the attachment surface of the air suction fixing jig 3a. It can be easily separated.

상기한 바와 같은 본 발명은 비철금속제 박판을 절삭 가공함에 있어 휨이나 뒤틀림의 문제를 근본적으로 해결하게 됨으로서, 30~40%이르던 불량률을 0~1% 수준으로 현저히 감소시켜 생산성 및 경제성을 크게 향상 시킬 수 있음은 물론 제품의가공 정밀도를 높여 품질 향상에도 크게 기여할 수 있게되는 우수한 효과가 있는 것이다.As described above, the present invention fundamentally solves the problem of bending and warping in cutting a non-ferrous metal sheet, thereby significantly reducing the defect rate from 30 to 40% to 0 to 1%, thereby greatly improving productivity and economy. In addition, it is possible to increase the processing precision of the product, and there is an excellent effect that can greatly contribute to quality improvement.
