Abstract
본 발명은 엘리베이터 카 도어용 레일 및 그 가공방법에 관한 것으로서, 더욱 상세하게는 레일의 재질을 일반구조용 탄소강관으로 하여 레일제작 공정의 편리성 및 간소화와 제품의 원가를 절감 시킬 수 있도록 한 것에 관한 것으로써, 일반구조용 탄소강 재질로 제작된 통상의 파이프 (100)를 인발기 (270)에 투입시켜 인발 가공하여 얻어진 타원형의 파이프(101)를, 레일형상을 이루도록 포밍 (Forming)작업 (300)하여 레일(110)이 형성되면, 상기 레일(100)의 일측면에 취부용 구멍 (115)을 펀칭작업 (400)하여 레일을 가공하는 것이다. 이렇게 가공된 레일 (100)은 일정 간격을 가지며 양측으로 행거롤러와 접하기에 적당한 중공부(111)와 원호부 (112)를 가지게 구성되어 중공부를 가지는 원호부가 레일의 상하로 각각 형성되어 레일 취부에 다른 방향성이 양호하고, 염가이며 재료가 풍부한 일반구조용 탄소강관을 원자재로 레일을 가공함으로 제품의 생산단가를 대폭 감소킬수 있을뿐만 아니라 제품의 가공공정수도 줄일수 있어 가공작업의 간편함과 편리성을 제공할 수 있는 아주 특출한 발명인 것이다.The present invention relates to a rail for an elevator car door and a processing method thereof, and more particularly, to the convenience and simplification of a rail manufacturing process and reduction of product cost by using a carbon steel pipe for general structure. In this case, the elliptical pipe 101 obtained by drawing a common pipe 100 made of carbon steel for general structure into the drawing machine 270 and drawing it is formed to form a rail shape (300). When the rails 110 are formed, the rails are processed by punching the mounting holes 115 on one side of the rails 100. The rail 100 processed as described above has a predetermined interval and has a hollow portion 111 and an arc portion 112 suitable for contact with the hanger rollers on both sides, and an arc portion having a hollow portion is formed above and below the rail, respectively. It is possible to reduce the production cost of the product by reducing the production cost of the product by processing the rail from the carbon steel pipe for general structure, which has good directionality, low cost, and abundant material. It is a very special invention that can be provided.
