본 발명은 슬라이드 언더레일 제조방법에 관한 것으로, 더 상세히는 프레스 금형 사이에 판재가 이송되면서 공정별로 순차적으로 제조하여 작업공정 및 제조단가를 절감할 수 있는 슬라이드 언더레일 제조방법에 관한 것이다.The present invention relates to a slide underrail manufacturing method, and more particularly, to a slide underrail manufacturing method that can reduce the work process and manufacturing cost by sequentially manufacturing by step as the plate material is transferred between the press mold.

종래의 슬라이드 레일은 서랍이 내재된 책상이나 캐비넷 또는 김, 등의 식물 을 넣어서 보관하기 위한 서랍이 적재된 김치냉장고, 식기세척기, 온냉장고, 와인냉장고 등 수납기구의 내측 양면에 설치되어 서랍을 원활하게 열리도록 한 금속판체의 레일로, 수납기구의 벽면에 체결수단에 의해 일체로 고정되는 외측레일과, 이 외측레일로분터 원활하게 움직이는 내측레일로 구성되며, 내측레일은 한개 또는 두 개의 내측레일로 구성되며, 상기 내측레일들 사이에는 원활하게 미끄럼동작을 위하여 다수개의 볼베어링이 설치된다.Conventional slide rails are installed on both sides of storage devices such as kimchi refrigerators, dishwashers, hot refrigerators, wine refrigerators, etc. with drawers for storing plants such as desks, cabinets or lavers with built-in drawers. The rail of the metal plate body to be opened so that the outer rail is integrally fixed to the wall surface of the storage device by the fastening means, and the inner rail is smoothly moved inner rail, the inner rail is one or two inner rail Consists of, a plurality of ball bearings are installed between the inner rails for a smooth sliding operation.

이러한 구성으로된 특허등록공고번호 제1993-1122호에 보는 바와 같이, 내측레일과 외측레일에 형성되어 잇는 각 굴곡연부와 이것에 의하여 쌓여지게 되어 있는 회전체의 상호 외주곡율이 대략 동일하게 형성되어 있을 뿐만 아니라, 상기 회전체간에 중간회전체를 회전자재하게 장설하는데 있어 내측레일과 외측레일의 내면측에 회전지지부를 돌설하고, 당해 지지부에 요조홈을 형성하여 이 요조홈에 이것과 외주곡율을 대략 동일하게 한 상기 중간회전체가 협지되도록 구성되었다.As shown in Patent Registration Publication No. 1993-1122 having such a configuration, the mutually outer circumferential curvatures of each bent edge formed on the inner rail and the outer rail and the rotating bodies piled up by this are formed to be substantially the same. In addition, in order to install the intermediate rotating body between the rotating bodies to rotate freely, the rotating support is protruded on the inner surface side of the inner rail and the outer rail, and the supporting groove is formed in the supporting groove to form this and the outer circumferential curvature. The intermediate rotors, which were approximately equal, were configured to be sandwiched.

이런 슬라이드 레일은 두께가 1.3-2.0 정도인 냉간 압연 강판을 롤 포밍(ROLL FORMMING)을 이용한 성형방법에 따라서 외측레일과 내측레일을 성형한 다음, 산처리로 세척하여 건조시키고, 이렇게 제작된 외측레일과 내측레일 사이에 다수개의 볼베어링을 수작업에 의해서 일정한 간격으로 삽입, 장작하여서 외측레일 내에서 내측레일이 원활하게 슬라이딩 이동되도록 이루어진다.This slide rail is formed by cold rolling steel sheet having a thickness of about 1.3-2.0 by forming the outer rail and the inner rail according to the forming method using roll forming, and then washing and drying by acid treatment, and thus the outer rail manufactured By inserting and firing a plurality of ball bearings at regular intervals between the inner and inner rails by hand, the inner rail is smoothly moved in the outer rail.

이러한 종래의 슬라이드 레일은 롤포밍에 의해 내외측레일의 몸체에 많은 절곡부위를 형성시키기 위해서 여러공정을 거쳐야 되기 때문에 구조상 작업공정이 복잡하고 작업시간이 많이 소요되는 문제점이 있었다.The conventional slide rail has a problem that the work process is complicated in structure and takes a lot of time because it has to go through several processes to form a large number of bent portions in the body of the inner and outer rails by roll forming.

상기 문제점을 해결하기 위한 본 발명은 프레스 금형을 구비하고, 이 프레스금형 사이로 판재를 투입하여 단계별로 언더레일을 제조하므로써, 작업공정 및 제조원가를 절감함과 아울러 내구성이 뛰어난 제품을 생산가능하여 제품에 대한 신뢰성을 확보할 수 있는 슬라이드 언더레일 제조방법을 제공할 목적이 있다.The present invention for solving the above problems is provided with a press mold, and by inserting a sheet material between the press mold to produce the underrail step by step, reducing the work process and manufacturing cost, and can produce a product with excellent durability to the product It is an object of the present invention to provide a method for manufacturing a slide underrail that can secure reliability.

상기 목적을 달성하기 위한 본 발명은 프레스 금형 사이로 순차적으로 이송되되, 원자재를 투입하여 규격화된 판재가 형성함과 동시에 이 판재의 일측에 복수의 체결공을 형성하는 피어싱단계와; 이송된 판재의 타측을 '
