일반적으로 공작기계에서는 금속재료를 절삭가공시 발생되는 칩(Chip)을 칩 컨베이어로 반송하여 수거하고 있다.In general, machine tools collect and transport chips generated during cutting to metal conveyors.

칩 컨베이어의 통상적인 구성은 철판을 힌지로 결합한 엔드레스 힌지벨트와, 힌지벨트의 양쪽으로 구비되는 체인과, 체인을 감아 돌리는 스프로켓으로 구성되며 칩 컨베이어는 공작기계의 종류, 가공조건, 작업장의 조건 등에 따라 다양한 길이와 폭을 가진 힌지 컨베이어가 소요되고 있다.The typical configuration of a chip conveyor consists of an endless hinge belt in which steel plates are hinged, a chain provided on both sides of the hinge belt, and a sprocket for winding the chain. The chip conveyor is a type of machine tool, processing conditions, workplace conditions, etc. Accordingly, hinge conveyors with various lengths and widths are required.

종래 칩 컨베이어의 힌지벨트 제작을 위한 힌지 플레이트는 철판을 블랭킹한 다음, 힌지로 결합되는 가장자리의 핀결합부를 성형하기 위하여 다단계의 밴딩공정 을 거쳐 힌지 플레이트의 핀 결합부를 성형하였으나 상기와 같은 개별 다단계작업은 생산성이 낮고 성형되는 힌지 플레이트의 핀 결합부를 진원상태로 서로 형상을 일치시키기 어려워 핀 조립작업에 어려움이 있었으며, 또한 다양한 폭을 가진 힌지 플레이트를 생산하기 위하여는 규격별로 각각의 금형을 확보하여야 한다는 문제점이 있었다.The hinge plate for manufacturing the hinge belt of the conventional chip conveyor is formed by blanking the iron plate and then forming the pin coupling portion of the hinge plate through a multi-step bending process to form the pin coupling portion of the edge coupled to the hinge, but the individual multi-step operation as described above. It was difficult to assemble the pin joints of the hinge plate to be molded in the shape of low productivity and difficult to assemble the shape of each other, and to produce a hinge plate of various widths, each mold must be secured according to the specifications. There was a problem.

본 발명은 힌지 플레이트를 정밀순차이송금형으로 불리는 프로그레시브(Progressive)금형장치를 이용하여 하나의 금형장치에서 순차적으로 사이드 컷팅 및 1,2,3차 밴딩공정을 거쳐 힌지 플레이트를 완성하고, 다양한 규격에 맞추어 힌지 플레이트를 원하는 폭으로 절단하는 절단공정을 거쳐 하나의 금형으로 다양한 규격의 힌지 플레이트를 제조할 수 있게 하는 것을 목적으로 한다.The present invention is to complete the hinge plate through the side cutting and 1,2,3rd bending process sequentially in one mold device using a progressive mold device called the hinge plate as a precision sequential transfer mold, to a variety of standards Through the cutting process of cutting the hinge plate to the desired width according to the purpose to be able to produce a hinge plate of various specifications with a single mold.

본 발명은 힌지 플레이트의 폭에 관계없이 힌지와 힌지의 간격이 일정한 점에 착안하여 힌지 플레이트의 폭과 동일한 스트립을 프로그레시브 금형장치로 공급하여 힌지 플레이트의 힌지부를 사이드 커팅하고, 힌지핀이 삽입되는 힌지부를 1,2,3차로 순차적으로 밴딩하여 성형한 다음 원하는 힌지 플레이트의 폭에 맞추어 스트립을 절단할 수 있게 하는 프로그레시브 금형장치를 제공한다.The present invention focuses on the constant distance between the hinge and the hinge regardless of the width of the hinge plate to supply a strip equal to the width of the hinge plate to the progressive mold device to side-cut the hinge portion of the hinge plate, the hinge pin is inserted Provided is a progressive mold apparatus that can be formed by bending the parts sequentially in the order of 1,2,3, and then cutting the strip according to the width of the desired hinge plate.

이상에서 설명한 바와 같이 본 발명은 힌지 플레이트를 정밀순차이송금형을 이용하여 하나의 금형으로 힌지 플레이트를 완성할 수 있게 하여 생산성을 향상하게 할 수 있으며, 다양한 규격의 폭을 가진 힌지 플레이트를 하나의 금형으로 제조할 수 있게 하여 설비투자비용을 절감할 수 있게 하는 효과가 있다.As described above, the present invention can improve the productivity by allowing the hinge plate to be completed in one mold by using the precision sequential transfer mold, and the hinge plate having a width of various specifications in one mold It is possible to reduce the cost of equipment investment by making it possible to manufacture.
