Abstract

본 발명은 프레스에 의한 구멍천공방법 및 구멍천공금형에 관한 것으로서, 상금형(1)과 하금형(2)으로 구성되고 상금형(1)에 가이드(3)를 갖는 구멍천공용 금형(4)에 있어서;상기 상금형(1)에는 소재(5)에 원형 또는 사각형등의 다양한 구멍을 천공할 시 소재(5)에 먼저 엠보싱을 형성할 수 있도록 엠보싱펀치(7)를 더 구비하고, 하금형(2)에는 엠보싱펀치(7)가 요입되는 홈(11)을 형성하고;엠보싱펀치(7)와 구멍천공 펀치(8)에는 전단면이 많토록 하기 위하여 모따기(9)를 하여;일차로 구멍(10)을 천공할 소재(5)에 엠보싱펀치(7)로 엠보싱을 형성한후 펀치(8)로 펀칭시 엠보싱에 의하여 미끄럼이 발생하여 전단면이 많토록 하여 구멍을 천공하는 것이 특징이다.The present invention relates to a hole punching method by a press and a hole punching mold, comprising a top mold (1) and a lower mold (2), and a hole punching die (4) having a guide (3) in the upper mold (1) In the upper mold (1) is further provided with an embossing punch (7) to form the first embossed in the material (5) when drilling a variety of holes, such as round or square in the material (5), (2) forms a groove 11 into which the embossing punch 7 is recessed; the embossing punch 7 and the hole punching punch 8 are chamfered 9 so as to have a large shear surface; The embossing punch 7 is formed on the material 5 on which the material 10 is to be drilled, and then, when punched with the punch 8, slip is generated by embossing, so that the shear surface is increased so that the hole is drilled.
