Description
본 발명은 철판 절단장치에 관한 것으로서, 더욱 상세하게는 철판이 올려지는 작업테이블에 스키드 다이(skid die) 및 펀치(punch)를 설치하되, 펀치가 하부로부터 상하 왕복하면서 접근하는 철판의 일단부를 절단하도록 구성함으로써 철판의 곡선 절단부위에 변형된 굴곡면이 발생하지 않도록 하면서 손쉽고 편리하게 절단작업을 할 수 있도록 하는 철판 절단장치에 관한 것이다.The present invention relates to an iron plate cutting device, and more particularly, a skid die and a punch are installed on a work table on which the iron plate is placed, and one end of the iron plate is approached while the punch is reciprocated from the bottom up and down. The present invention relates to an iron plate cutting device that enables easy and convenient cutting operation while preventing the curved curved surface of the iron plate from being curved.
일반적으로, 차량의 제작 공정에서 사용되는 비교적 얇은 철판(1.2mm 이하의 두께를 갖는 철판)을 곡선 절단할 경우에는 판금가위를 사용하고 있으며, 비교적 두꺼운 철판(1.2mm 이상의 두께를 갖는 철판)을 곡선 절단할 경우에는 띠톱 기계(band saw machine)를 사용하고 있다.Generally, sheet metal scissors are used to cut and cut a relatively thin iron plate (steel plate having a thickness of 1.2 mm or less) used in the manufacturing process of a vehicle, and a relatively thick iron plate (steel plate having a thickness of 1.2 mm or more) is curved. In the case of cutting, a band saw machine is used.
그런데, 철판의 곡선 절단작업시 판금가위의 경우에는 조작이 간편하지만, 절단부위에 가위날에 의해 변형된 굴곡부를 형성하게 되어 절단작업후에는 해머작업 등으로 면수정작업을 해야하는 문제점이 있다.By the way, in the case of sheet metal scissors during the curve cutting of the iron plate, the operation is easy, but the bent portion deformed by the shear blades formed on the cutting portion, there is a problem that the surface modification work, such as hammer work after the cutting operation.
또한, 띠톱 기계의 경우에는 동력에 의해 일정궤도로 이동하는 띠톱날을 통해 철판을 절단하게 되므로, 철판의 곡선절단이 어렵게 됨은 물론 곡선절단 후에는 절단부위를 줄작업(filing)을 통해 마무리해야 하는 번거로움의 문제점이 있다.In addition, in the case of the band saw machine, since the iron plate is cut through the band saw blade moving in a constant orbit by power, it becomes difficult to cut the curve of the iron plate, and after finishing the curve, the cutting part must be finished by filing. There is a problem of hassle.
따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로서, 철판의곡선 절단작업시 절단부위에 변형된 굴곡면이 발생하지 않도록 함은 물론 손쉽고 편리하게 철판을 절단할 수 있도록 하는 철판 절단장치를 제공하는 데 그 목적이 있다.Therefore, the present invention has been made in view of the above problems, the iron plate cutting device that can be easily and conveniently cut the iron plate as well as not to be deformed curved surface in the cutting portion during the cutting operation of the iron plate The purpose is to provide.

또한, 펀치 가동부(50)는 펀치(30)를 상하 왕복운동시켜 철판(2)을 전달하기 위한 전달력을 제공하는 것으로, 펀치 가동부(50)는 프레임(11)의 하단에 설치되어 수평방향을 기준으로 회전하는 캠축(52)을 갖는 기어드 모터(51)(geared motor)와, 상단이 지지판(41)의 하단에 회동가능하게 결합되고 하단이 기어드 모터(51)의 회전운동을 상하 왕복운동으로 변환시키도록 캠축(52)과 캠구조로 결합되는 커넥팅 로드(53)로 구성된다. 이 커넥팅 로드(53)는 2단으로 분리되어 턴버클(turn buckle)구조로 길이 조절이 가능하도록 이루어지고, 상단부에는 지지판(41)의 볼홈(43)과 결합되어 볼조인트를 구성하기 위한 볼(54)이 부착되며, 하단부에는 기어드 모터(51)의 캠축(52)과 캠조인트를 구성하기 위한 캠링(55)이 부착된다.In addition, the punch movable part 50 provides a transmission force for transmitting the iron plate 2 by reciprocating the punch 30 up and down, and the punch movable part 50 is installed at the lower end of the frame 11 to provide a horizontal direction. A geared motor 51 having a camshaft 52 that rotates as a reference, and an upper end thereof are rotatably coupled to a lower end of the support plate 41, and a lower end of which rotates the geared motor 51 in a vertical reciprocating motion. It consists of a connecting rod 53 coupled to the cam shaft 52 and the cam structure to convert. The connecting rod 53 is divided into two stages so that the length can be adjusted in a turn buckle structure, and the upper end portion is coupled to the ball groove 43 of the support plate 41 to form a ball joint 54. ) Is attached, and a cam ring 55 for constituting the cam joint and the cam shaft 52 of the geared motor 51 is attached to the lower end.
이와 같이 구성되는 본 발명의 실시예에 따른 철판 절단장치(1)의 작용을 설명하면 다음과 같다.Referring to the operation of the iron plate cutting device 1 according to an embodiment of the present invention configured as described above are as follows.
우선, 절단작업을 위한 철판(2)을 작업 테이블(10)에 올려놓고 펀치 가동부(50)의 기어드 모터(51)에 전원을 인가하여 작동시키게 되면, 기어드모터(51)의 캠축(52) 회전력은 캠링(55)과의 캠구조를 통해 커넥팅 로드(53)를 상하 왕복운동시키게 된다. 이때, 커넥팅 로드(53)와 볼조인트로 결합된 펀치 지지부(40)의 지지판(41)은 가이드핀(45)을 따라 반복 승강되고, 그 지지판(41)에 고정된 펀치(30)는 스키드 다이(20)의 슬라이드공(43)에서 반복 승강하게 된다.First, when the iron plate 2 for cutting work is placed on the work table 10 and the power is applied to the geared motor 51 of the punch movable part 50 to operate the cam shaft 52 of the geared motor 51. The reciprocating motion of the connecting rod 53 up and down through the cam structure with the cam ring 55. At this time, the support plate 41 of the punch support part 40 coupled with the connecting rod 53 and the ball joint is repeatedly lifted along the guide pin 45, and the punch 30 fixed to the support plate 41 is a skid die. The slide hole 43 of 20 is repeatedly raised and lowered.
이렇게 펀치(30)가 승강되는 과정에서, 작업 테이블(10)에 올려진 철판(2)의 절단부위를 펀치(30)의 삽입부(33)로 밀어넣게 되면 상승되었다가 하강하는 펀치(30)의 커팅부(31)는 스키드 다이(20)의 지지를 통해 삽입부(33)로 밀어 넣어진 철판(2)의 절단부위를 펀칭하여 절단하게 된다.In this process of lifting the punch 30, when the cut portion of the iron plate 2 mounted on the work table 10 is pushed into the insertion portion 33 of the punch 30, the punch 30 is raised and lowered. The cutting portion 31 of the cutting is punched by cutting the cut portion of the iron plate (2) pushed into the insertion portion 33 through the support of the skid die (20).
이와 같이 철판(2)을 절단방향에 따라 방향 조절하면서 계속하여 펀치(30)의 삽입부(33)로 밀어넣게 되면 펀치(30)의 커팅부(31)는 삽입방향을 따라 철판(2)을 연속적으로 절단하게 되므로 철판(2)의 직선 절단작업은 물론 곡선 절단작업이 용이해지고, 또한 스키드 다이(20)에 놓인 철판(2)을 펀치(30)의 펀칭을 통해 절단하게 되므로 철판(2)의 절단부위에 변형된 굴곡면이 발생하지 않게 된다.As such, when the steel plate 2 is oriented along the cutting direction and continuously pushed into the insertion part 33 of the punch 30, the cutting part 31 of the punch 30 moves the iron plate 2 along the insertion direction. Since the cutting is continuous, straight cutting of the iron plate (2) as well as the curve cutting operation is easy, and also the iron plate (2) placed on the skid die 20 is cut through the punching of the punch (30) iron plate (2) Deformed curved surface does not occur in the cut portion of the.
이상에서 살펴본 바와 같이, 본 발명은 철판이 올려지는 작업 테이블에 스키드 다이 및 펀치를 설치하되 펀치가 하부로부터 상하 왕복하면서 접근하는 철판의 일단부를 절단할 수 있게 됨으로써 철판의 곡선 절단부위에 변형된 굴곡면이 발생하지 않도록 하면서도 손쉽고 편리하게 철판을 절단할 수 있게 되는 것이다.As described above, in the present invention, the skid die and the punch is installed on the work table on which the iron plate is mounted, but the punch is deformed to the curved cut portion of the iron plate by cutting one end of the iron plate approaching while reciprocating up and down from the bottom. It is possible to cut the iron plate easily and conveniently while preventing the occurrence of cotton.
