본 고안은 컴퓨터의 샤시 프레임과 같은 대형 제품(U-Be)을 밴딩하는 외곽캠식 밴딩금형에 관한 것으로, 특히 펀치홀더에 홀딩되어 슬라이딩되는 캠펀치의 가이드를 재량하여 가공 및 조립이 간편하도록 안출한 외곽캠식 밴딩금형의 캠펀치가이드에 관한 것이다.The present invention relates to an outer cam banding mold for bending a large product (U-Be), such as a chassis frame of a computer, and in particular, a guide of a cam punch that is held and slid in a punch holder is discreetly designed for easy processing and assembly. The present invention relates to a cam punch guide of an outer cam banding mold.

상기 외곽캠식 밴딩금형은 제1도와 같이 제품(10)의 성형을 위해 받쳐주는 다이(2)와, 캠펀치(5)를 안내하는 펀치가이드(3)로 구성된 다이홀더(1)와; 탄력있게 좌, 우 슬라이딩되도록 제품(10)을 밴딩하는 양측 캠펀치(5)와, 양측 캠펀치(5)를 홀딩하여 이동거리를 제어하도록 저면에 고정설치되는 제어부(6)로 구성하여 상, 하 작동되는 펀치홀더(4)로 구성되어 있다.The outer cam type bending mold includes a die holder (1) comprising a die (2) supporting the forming of the product (10) and a punch guide (3) for guiding the cam punch (5); It consists of both sides of the cam punch (5) for bending the product 10 so as to elastically slide left and right, and a control unit (6) fixed to the bottom to hold the two cam punch (5) to control the moving distance It consists of a punch holder (4) which is operated below.

이때 상기 캠펀치(5)는 제2도와 같이 양측에 안내턱(51)을 형성하여 펀치홀더(4)의 양측에 고정설치된 안내판(41)의 안내를 받아 좌, 우 슬라이딩되게 하며, 펀치홀더(4)와 캠펀치(5)의 사이에 웨어플레이트(7)를 설치하여 캠펀치(5)의 충격을 흡수하는 동시에 원활하게 슬라이딩되도록 구성되어 있다.At this time, the cam punch 5 is formed by the guide jaw 51 on both sides as shown in Figure 2 to receive the guide of the guide plate 41 fixed to the both sides of the punch holder 4 to slide left and right, punch holder ( The wear plate 7 is provided between the cam punch 5 and the cam punch 5 to absorb the impact of the cam punch 5 and to slide smoothly.

그런데 캠펀치(5)의 슬라이드면인 안내턱(51)의 가공시 캠펀치(5) 자체의 규격이 너무 커서 가공이 매우 어렵고, 정밀가공된 슬라이드면에 모든 충격과 하중이 걸리게 되므로 캠펀치의 반복적인 사용시 그 슬라이드면이 손상되거나 오차가 심하게 되어 캠펀치에 의하여 밴딩되는 제품의 규격이 변형되어 불량률이 높아지게 되었던 것이며, 이로인해 새로운 캠펀치자체로 교체하여야 되는 부담과 교체작업에 따르는 불편한 문제점 등이 있었다.However, when machining the guide jaw 51, which is the slide surface of the cam punch 5, the size of the cam punch 5 itself is so large that the processing is very difficult, and all impacts and loads are applied to the precision processed slide surface. When repeated use, the slide surface is damaged or the error is severe, and the standard of the product banded by the cam punch is deformed and the defect rate is increased. There was this.

본 고안은 이러한 종래의 문제점을 해결하고자 안출한 것으로, 캠펀치의 양측에 별도의 보조안내판을 각각 조립하도록 하므로서 슬라이드면의 가공 및 조립을 간단하게 하고, 캠펀치의 반복적인 사용시 슬라이드면이 손상되거나 오차의 발생시 캠펀치는 교체하지 않고 보조안내판만 교체토록 하여 금형비의 절감과 교체작업의 편리함을 제공하며, 밴딩되는 제품의 불량률을 현저히 낮추고자 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, to simplify the processing and assembly of the slide surface by assembling a separate auxiliary guide plate on each side of the cam punch, the slide surface is damaged when repeated use of the cam punch When the error occurs, the cam punch does not replace, but replaces only the auxiliary guide plate, thereby reducing mold cost and convenience of replacement work, and aiming to significantly reduce the defective rate of the banded product.

이하 본 고안을 첨부도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.

도면 제1도, 제3도 내지 제5도는 본 고안의 실시예로써, 다이홀더(1)에 제품(10)의 성형을 위해 받쳐주는 다이(2)와, 캠펀치(5)를 안내하는 펀치가이드(3)를 설치하며, 캠펀치(5)의 양측을 펀치홀더(4)의 안내판(41)에 좌, 우 슬라이딩되게 설치하고, 펀치홀더(4)과 캠펀치(5)의 사이에 웨어플레이트(7)를 설치하여 캠펀치(5)의 충격을 흡수하는 동시에 원활하게 슬라이딩되도록 하고, 양측 캠펀치(5)를 홀딩하여 좌, 우 이동거리를 제어하도록 펀치홀더(4)의 저면에 고정설치되는 제어부(6)로 구성한 외곽캠식 밴딩금형에 있어서, 상기 캠펀치(5)의 양측에 설치요홈(52)을 각각 형성한 뒤 별도의 보조안내판(8)을 형합시켜 보울트(9)로 각각 조립하여 일체화 한뒤 보조안내판(8)의 끝단을 상기 펀치홀더(4)의 안내판(41)에 슬라이딩되게 설치한 것이 본 고안의 특징이다.1 and 3 to 5 are embodiments of the present invention, a die 2 supporting the die holder 1 for forming the product 10 and a punch for guiding the cam punch 5. The guide 3 is installed, and both sides of the cam punch 5 are installed on the guide plate 41 of the punch holder 4 so as to slide left and right, and the wear is between the punch holder 4 and the cam punch 5. The plate 7 is installed to absorb the impact of the cam punch 5 and to slide smoothly, and is fixed to the bottom of the punch holder 4 to control the left and right movement distance by holding both cam punches 5. In the outer cam type banding mold composed of the control unit 6 to be installed, each of the installation grooves 52 are formed on both sides of the cam punch 5, and then a separate auxiliary guide plate 8 is formed to form a bolt 9, respectively. After assembling and assembling, the end of the auxiliary guide plate 8 is slidably installed on the guide plate 41 of the punch holder 4.

캠펀치(5)의 양측에 형성된 설치요홈(52)은 보조안내판(8)과의 접촉면적을 넓혀 견고하게 고정되도록 한다.Installation grooves 52 formed on both sides of the cam punch 5 widen the contact area with the auxiliary guide plate 8 to be firmly fixed.

상기 보조안내판(8)과 안내판(41)는 상호 원활하게 슬라이딩되게 정밀가공하며, 또한 상호 슬라이드면에 오일홈(81)(42)을 형성하여 마찰력을 최소화한다.The auxiliary guide plate 8 and the guide plate 41 are precisely processed to slide smoothly with each other, and also minimize oil friction by forming oil grooves 81 and 42 on mutual slide surfaces.

이와 같이 구성된 본 고안은, 캠펀치(5)의 양측에 종래와 같이 안내턱을 직접 정밀 가공하지 않고, 별도의 보조안내판(8)을 정밀 가공하여 캠펀치(5)의 양측에 각각 조립하여 주므로서 대형의 캠펀치(5)에 안내턱을 정밀 가공하는데 따르는 어려움을 해결하고, 또한 조립이 매우 간단하여 캠펌치(5)의 가공시간을 단축시킬 수 있는 것이다.The present invention constructed as described above does not directly process the guide jaw on both sides of the cam punch 5, but instead, the auxiliary guide plate 8 is precisely processed and assembled on both sides of the cam punch 5, respectively. This solves the difficulty of precision machining the guide jaw in the large cam punch 5, and also the assembly is very simple to shorten the processing time of the cam pump (5).

그리고 캠펀치(5)의 양측에 설치요홈(52)을 형성할때 슬라이드면과 같이 정밀가공하지 않아도 보조안내판(8)과는 정확하게 가능하고, 또한 정밀가공된 보조안내판(8)에 의하여 펀치홀더(4)의 안내판(41)과 원활하게 슬라이디오디므로 캠펀치(5)의 기능에 전혀 지장이 없게 되는 것이다.And when forming the mounting groove 52 on both sides of the cam punch (5), even if the precision processing, such as the slide surface is possible accurately with the auxiliary guide plate (8), and also the punch holder by the precision guide plate (8) Since the slide plate smoothly plays with the guide plate 41 of (4), the function of the cam punch 5 is not impaired at all.

또, 캠펀치(5)의 양측에 설치요홈(52)과 보조안내판(8)의 접촉면적을 넓혀 조립시 견고하게 고정되도록 하여 캠펀치(5)의 정확한 안내와 슬라이딩되게 할수가 있는 것이다.In addition, the contact area between the installation groove 52 and the auxiliary guide plate 8 is widened on both sides of the cam punch 5 to be firmly fixed during assembly so that the cam punch 5 can be accurately guided and slid.

이와 같이 캠펀치(5)의 양측에 별도의 보조안내판(8)을 각각 조립하도록 하므로서 슬라이드면의 가공 및 조립이 매우 간단하고, 캠펀치(5)의 반복적인 사용시 슬라이드면이 손상되거나 오차의 발생시 캠펀치(5)는 교체하지 않고 보조안내판(8)만 교체토록 하여 금형의 절감과 교체작업의 편리함을 제공하며, 이로인해 밴딩되는 제품의 불량률을 현저히 낮출수가 있는 것이다.In this way, as the separate auxiliary guide plates 8 are assembled on both sides of the cam punch 5, the processing and assembly of the slide surface is very simple, and when the slide surface is damaged or an error occurs when the cam punch 5 is repeatedly used. Campunch (5) is to replace only the auxiliary guide plate (8) without replacement to provide a reduction of the mold and the convenience of the replacement operation, thereby lowering the defective rate of the banded product significantly.
