본 고안은 프레스에 설치하여 일정한 설계 칫수로 가공물의 표면을 펀칭 가공하는 타발금형(他拔金型)에 관한 것으로, 특히, 절단각의 보수가 용이하고, 하부금형의 틀어짐을 방지하여 생산성을 높이고자 하는 타발금형의 펀치에 관한 것이다.The present invention relates to a punching die which is installed on a press to punch the surface of a workpiece with a certain design dimension. In particular, the cutting angle is easy to repair, and the lower mold is prevented from twisting to increase productivity. It relates to a punch of a punching die.
프레스에 설치하여 프레스의 구동으로 금형을 통과하는 가공물을 펀칭하는 타발 금형은 대부분이 제1도에 도시한 것과 같이 절단각(α°)을 선단에 형성한 펀치(5)와 가이드핀(6) 및 스트리퍼(8)을 설치하는 상금형(1)과 펀칭용 구멍(11)이 뚫린 다이(9)를 고정한 하금형(2)으로 구성되어 하금형(2)은 프레스의 공작대에 설치하고, 상금형(1)은 프레스의 램에 설치하여 램의 상하 구동으로 가공물의 소정위치에 펀칭을 하였다.In the punching die which is installed in the press and punches the workpiece passing through the mold by driving of the press, the punch 5 and the guide pin 6, each of which has a cutting angle α ° formed at the tip as shown in FIG. And a lower die 2 for fixing the die 9 to which the stripper 8 is installed and the die 9 for which the punching hole 11 is drilled. The lower die 2 is installed on the workbench of the press. The mold 1 was attached to the ram of a press, and was punched at the predetermined position of the workpiece by the vertical movement of the ram.
그러나 종래의 펀칭과정에서 가공물은 제2도와 같은 펀치의 절단각(α°)에 의해 순차적으로 펀칭되어, 펀칭순간에 많은 힘이 요구되었고, 펀치의 선단 즉 펀치의 절단각 위치가 동일위치의 수평선상에 있으므로 펀치의 선단들이 가공물에 동시에 닿아 다이(9)와 하측판(2) 이 뒤틀어지는 폐단이 있었을 뿐만 아니라 절단각을 재연마 하기 위해서는 상금형(1) 모두를 분해 해야 펀치의 절단각(α°)을 연마할수 있는 폐단이 있었고, 또한 분해된 상측 금형(2)을 조립함에 있어서도 분해된 모든것은 조립해야 하는 번거러움이 있어 금형의 구조가 효율적이지 못하여 생산능률이 저하되었던 것이다.However, in the conventional punching process, the workpiece is punched sequentially by the cutting angle (α °) of the punch as shown in FIG. 2, so that a lot of force is required at the moment of punching, and the cutting edge position of the punch, that is, the horizontal line of the punching position As the upper end of the punch touches the workpiece at the same time, the die 9 and the lower plate 2 are distorted and the upper die 1 must be disassembled in order to regrind the cutting angle. α °) had a closed end, and also in assembling the disassembled upper mold 2, all the disassembled parts had to be assembled, and the structure of the mold was not efficient and the production efficiency was reduced.
이러한 종래의 문제점을 해결하기 위한 본 고안은 홀다에 고정하는 수개의 펀치이 길이를 순차적으로 길게 펀치군을 형성하여 홀다의 축선을 기준으로 펀치군에 좌우로 경사진 절단각을 형성하여서 가공물의 펀칭이 순간적으로 이루어지게 하고, 특히 절단각이 수개의 펀치로 형성되는 펀치군에 형성되여 용이한 펀칭과 함께 절단각의 재 연마시 금형을 분해 하지 않으면서도 절단각을 보수를 할수 있도록 하는 것으로, 이를 첨부 도면에 따라 상세하게 설명하면 다음과 같다.The present invention for solving the conventional problems is to punch the workpiece by forming a cutting group inclined to the left and right punch group on the basis of the axis of the holder by forming a punch group of several punches fixed in the hold sequentially. It is made instantaneously, and especially the cutting angle is formed in the punch group formed by several punches, so that the cutting angle can be repaired without disassembling the mold when regrinding the cutting angle with easy punching. When described in detail according to the drawings as follows.
제3도는 본 고안에 따른 펀치의 상태도로 가이드 핀(6)과 함께 홀다(4)에 부착되는 펀치(5)는 그 길이(L)가 각각 틀리게 하여서 홀다(4)의 축선(X) 위치에는 길이가 짧은 것을 고정하고, 좌우측 방향으로 길이가 긴 것을 고정하여 펀치군(6)을 형성한다.3 is a state of the punch according to the present invention, the punch 5 attached to the holder 4 together with the guide pin 6 has its length L different, so that the position of the punch 4 in the axis X position of the holder 4 is different. The shorter one is fixed, and the longer one is fixed in the left and right directions to form the punch group 6.
그리고 펀치(5)의 저면으로는 일측 방향으로 만 기울어진 경사면(5a)을 형성한다.And as the bottom face of the punch 5, the inclined surface 5a inclined only in one side direction is formed.
상기의 경사면(5a)은 길이가 중앙으로 좌우로 순차적으로 길어진 펀치군(6)에서 절단각(β)을 형성하는 것이다.The inclined surface 5a forms a cutting angle β in the punch group 6 in which the length is sequentially lengthened sequentially from the left to the center.
이러한 구성으로 이루어진 본 고안은 종래와 같이 상측 금형(1)에 홀다(4)를 고정시켜 사용하는 것으로 프레스의 램이 상사점 위치에서 가공물이 놓인 하금형(2)의 다이(9)로 하강하여 가공물을 펀칭한다.According to the present invention having the above configuration, the holder 4 is fixed to the upper mold 1 as in the prior art, and the ram of the press descends to the die 9 of the lower mold 2 in which the workpiece is placed at the top dead center position. Punch the workpiece.
이때의 절단 상태는 다이(9)와 하금형(2)에 충격을 주지 않는다.The cutting state at this time does not impact the die 9 and the lower die 2.
이를 좀더 자세하게 설명하면, 하강하는 펀치(5)가 가공물에 닿을때에는 펀치(5)군이 동일하게 닿는 것이 아니고, 좌우측의 펀치(5)만이 가공물에 닿아 절단작용을 이루고 계속적인 램의 하강으로 가공물과 펀치(5)와의 접촉은 홀다(4)의 축선위치로 이동한다.In more detail, when the descending punch 5 touches the workpiece, the punch 5 groups do not touch the workpiece equally, and only the left and right punches 5 touch the workpiece to achieve a cutting action, and the workpiece is continuously lowered. And contact with the punch 5 move to the axial position of the hold 4.
그러므로 본 고안에 의한 펀치는 가공물의 좌우측이 먼저 펀칭되면서 중앙부에 펀칭되어 가공물은 마치 가위 혹은 샤링기 등으로 절단되는 동작을 이루는 것이다.Therefore, the punch according to the present invention is punched in the center while the left and right sides of the workpiece are punched first, so that the workpiece is cut by scissors or a shearing machine.
그러므로 가공물에 순간적으로 가해지는 충격은 매우 작아지면서 펀칭 작업이 순간적으로 이루어진다.The momentary impact on the workpiece is therefore very small and the punching operation takes place instantaneously.
또한 본 고안은 펀치의 절단각 보수시 상측 금형(1)을 램에서 분리시켜 펀치(5)를 분해하지 않고서도 절단각(β)을 재연마 할수 있는데 이는 펀치(5)의 저면이 일측방향으로만 경사졌기 때문이다.In addition, the present invention can separate the upper mold (1) from the ram when repairing the cutting angle of the punch, so that the cutting angle (β) can be regrind without disassembling the punch (5). Only because it is inclined.
그러므로 타발작업에는 편칭상태의 안정화를 기할수 있고, 재연마 작업시에는 작업이 편리해진다.Therefore, the punching work can be stabilized in a biased state, and the work is convenient at the time of regrinding work.
특히, 펀칭 순간에는 미소한 충격이 가해지므로서 펀치의 절단각 보호와 금형의 뒤틀어짐을 방지할수 있는것이다.In particular, a minute impact is applied at the moment of punching, thereby preventing the cutting angle of the punch and the warping of the mold.
이상에서와 같이 본 고안은 프레스의 램에 부착하는 홀다의 펀치군에 절단각을 형성하므로서 펀칭시의 충격을 현저하게 줄어는 효과로 금형의 사용시간을 연장시키는 잇점이 있어 경제적이고, 절단각 보수시에 금형을 분해하지 않고서도 펀치의 절단각을 연마할수 있어 작업에 편리한 특징이 있는 프레스 타발 금형의 펀치인 것이다.As described above, the present invention forms an angle of cutting in the punch group of the holders attached to the ram of the press, thereby significantly reducing the impact at the time of punching. It is a punch of the punching punch die which can grind the cutting angle of the punch without disassembling the mold at the time and is convenient for work.
