로터리 다이보드 및 그 제작방법{A rotary die-board and the manufacturing method}Rotary die board and its manufacturing method

본 발명은 커팅블레이드를 장착하고 종이박스용 판지를 절단가공하는 로터리 다이보드 및 그 제작방법에 관한 것으로, 특히 절단되는 종이박스에 부합하게 절곡시킨 후 곡선칼날부분에 노치를 형성하고 지지부의 곡면에 상응하게 만곡시켜 곡선형 칼날부를 형성함으로써 간단하게 일체형의 커팅블레이드를 원통형의 지지부에 장착할 수 있게 한 로터리 다이보드 및 그 제작방법에 관한 것이다.The present invention relates to a rotary die board for mounting a cutting blade and cutting a cardboard for a paper box, and to a method for manufacturing the same, in particular to form a notch on the curved blade after bending to conform to the paper box to be cut and on the curved surface of the support The present invention relates to a rotary die board and a method of manufacturing the same, by forming a curved blade portion correspondingly curved to simply mount the integrated cutting blade to a cylindrical support.

일반적으로, 종이박스는 두꺼운 종이를 접어서 제작하게 되며, 이러한 박스용 판종이를 접기 위해서는 박스제작용 판종이의 내측부분을 일정깊이로 압인하여 접는선을 형성하고 그 외곽을 박스형태에 따라 절단해야 한다. 이와 같은 판종이의 접는 선은 접는 선과 동일한 형태로 커팅블레이드를 판재에 착설한 후, 이 커팅블레이드가 설치된 판재로 박스형 판종이를 눌러 압입함으로써 접는선을 형성하게 된다. 이와 같이 커팅블레이드를 박스의 접는 선과 같이 절곡된 형상을 갖도록 제작하기 위해서 커팅블레이드 가공장치가 개발되었다. 이러한 가공장치는 통상 평면적인 보드에 장착되는 것으로, 그에 따라서 커팅블레이드도 평면상에서 절곡되어 2차원적인 절곡이 이루어졌다.In general, paper boxes are manufactured by folding thick paper. To fold a sheet of paper for this box, it is necessary to press the inner part of the box-making sheet paper to a certain depth to form a folding line, and cut the outline according to the box shape. do. The folding line of the sheet paper is formed in the same form as the folding line to form a folding line by pressing the box-shaped sheet paper with the plate, the cutting blade is installed on the plate. As such, the cutting blade processing apparatus has been developed to manufacture the cutting blades to have a bent shape such as a folding line of a box. Such a processing apparatus is usually mounted on a planar board, and accordingly, the cutting blade is also bent on a plane to make a two-dimensional bending.

그러나, 회전하며 종이박스를 절단하거나 접는선을 형성하기 위해 압인하는 롤러식의 로터리 다이보드가 개발됨에 따라서 커팅블레이드도 또한 3차원적으로 가공되어야 할 필요성이 대두되었다. 보편적으로 기존에는 띠형의 판상 커팅블레이드를 로터리의 롤러곡면부에 적합하게 찌그러뜨리거나 그 곡면에 부합되게 절단하여 곡선형의 칼날부를 형성하였다. 그러므로, 로터리 다이보드에 맞는 곡선형의 칼날부를 가공하기가 까다로울 뿐만 아니라, 고정밀도를 요해 생산성이 떨어지고 제작비가 상승하는 문제점을 야기시켰다. 또한, 종래에는 곡선형 칼날부와 직선형 칼날부를 개별적으로 제작하여 로터리다이보드에 취부함으로써 그 연결접촉부위가 고속회전시 틈이 벌어져 종이박스가 제대로 절단되지 않을 뿐더러 다이보드의 고장 및 파손이 빈번히 발생하는 폐단이 있었다.However, with the development of roller-type rotary die boards that rotate and press to cut paper boxes or form creases, the need for cutting blades also has to be processed in three dimensions. Conventionally, the band-shaped cutting blade is crushed appropriately to the roller curved portion of the rotary or cut to conform to the curved surface to form a curved blade portion. Therefore, not only it is difficult to process the curved blade portion that fits the rotary die board, but also requires a high precision, causing a problem of low productivity and high manufacturing cost. In addition, conventionally, the curved blade portion and the straight blade portion are separately manufactured and mounted on the rotary die board, so that the connection contact portion opens a gap during high-speed rotation, so that the paper box is not cut properly and the breakdown and breakage of the die board frequently occurs. There was a dismissal.

따라서, 본 발명의 목적은 상기에서와 같은 종래의 결점들을 해소하기 위해서 안출한 것으로서, 절단되는 종이박스에 부합되게 절곡시켜 평면상태의 직선/곡선칼날부분을 생성한 후 그 곡선칼날부분에 노치를 형성하고 지지부의 곡면에 상응하게 만곡시켜 곡선형 칼날부를 형성함으로써 간단하게 일체형의 커팅블레이드를 원통형의 지지부에 장착한 로터리 다이보드를 제공함에 있다.Therefore, an object of the present invention is to devise to solve the above-mentioned conventional defects, to be bent in accordance with the paper box to be cut to produce a straight line / curved blade portion of the planar state and then the notch on the curved blade portion The present invention provides a rotary die board in which an integrated cutting blade is simply mounted on a cylindrical support by forming a curved blade by forming and curved corresponding to the curved surface of the support.

또한, 본 발명의 다른 목적은 상기한 로터리 다이보드를 제작하는 방법을 제공하는 데 있다.Another object of the present invention is to provide a method of manufacturing the rotary die board.
