Description

절단 금형{trim die}Cutting dies {trim die}

본 발명은 절단 금형에 관한 것으로서, 보다 상세하게는 제품 절단면의 품질향상 및 블레이드를 장기간 사용할 수 있도록 된 새로운 구조의 절단금형에 관한 것이다.The present invention relates to a cutting mold, and more particularly, to a cutting mold of a new structure, which allows the long-term use of the improved quality of the product cutting surface and the blade.

일반적으로, 절단 금형은 한쌍의 절단날을 사용하여 소재를 절단하는 것으로서, 도 1에 도시된 바와 같이, 프레스의 램에 결합되며 소정형상의 블레이드(4)가 구비된 상부 금형(2)과, 프레스의 베드에 결합되며 상기 블레이드(4)와 맞물리는 커팅다이(8)가 구비된 하부 금형(6)으로 구성된다. 따라서, 피가공물(1)을 상기 커팅다이(8) 위에 올려놓은 상태에서 상부 금형(2)을 하강시켜 이 상부 금형(2)의 블레이드(4)가 커팅다이(8)와 맞물려 피가공물(1)의 둘레부를 절단하도록 구성된다.In general, the cutting mold is to cut the material using a pair of cutting blades, as shown in Figure 1, the upper mold (2) coupled to the ram of the press and provided with a blade 4 of a predetermined shape, It consists of a lower mold 6 which is coupled to the bed of the press and has a cutting die 8 which engages the blade 4. Accordingly, the upper die 2 is lowered while the workpiece 1 is placed on the cutting die 8 so that the blade 4 of the upper die 2 meshes with the cutting die 8 so that the workpiece 1 Is cut to a periphery.

그런데, 이러한 절단 금형은 블레이드(4)와 커팅다이(8) 사이에 일정한 공간 즉, 클리어런스가 있어야 블레이드(4)가 커팅다이(8)의 둘레부에 맞물려 하강되면서 피가공물(1)을 절단하게 되므로, 전단면에 거스러미(burr)가 발생하여 깔끔하지 못하였다.However, such a cutting mold requires a certain space, that is, a clearance, between the blade 4 and the cutting die 8 to cut the workpiece 1 while the blade 4 is engaged with the circumference of the cutting die 8 and lowered. As a result, burrs were generated on the shear surface, which was not neat.

특히, 섬유질이 함유된 피가공물(1)은 절단시 블레이드(4)와 커팅다이(8) 사이의 클리어런스를 통해 블레이드(4)가 섬유질을 끌고 내려가면서 절단하므로, 올바르게 절단되질 않고 절단면에 거스러미가 더욱 심하게 발생되고 정확하게 절단되지 않는 문제점이 있다. 특히, 절단시 섬유질을 끌고 내려가게 되므로 반복작업시 섬유질에 의해 블레이드(4)의 날부가 쉽게 손상되는 문제점이 있다.In particular, the workpiece 1 containing the fiber is cut by pulling the fiber down and pulling the fiber through the clearance between the blade 4 and the cutting die 8 when cutting, so that the cut surface is not cut correctly There is a problem that occurs more severely and is not cut accurately. In particular, since the fiber is pulled down when cutting, there is a problem that the blade portion of the blade 4 is easily damaged by the fiber during the repetitive operation.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 제품 절단면의 품질향상 및 블레이드를 장기간 사용할 수 있도록 된 새로운 구조의 절단 금형을 제공하기 위한 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a cutting mold of a new structure that can improve the quality of the product cutting surface and the blade can be used for a long time.
