Abstract

The device for mfg. guide rails of a drawer includes a strip roll (10), a number of rollers having shape-grooves and protrusions, and a cutting grinder (19). The steel strip with a predetermined width is continuously fed into a driving roller (6), and then into a number of forming rollers so as to be formed in a channel shaped cross-section. After passing the gap of aux. rollers (7,7') the channel shaped strip is formed to have roundshaped ribs. The cutting grinder cuts the strip into a predetermined length after fixing rollers (9,9') straighten the buckled or bent guide rail.

본 발명은 철재나 목재의 가구중에 서랍체가 있는 책상이나 화일박스등에 설치되어 서랍체를 열고 닫을때 그 작동을 원활하게하는 안내레일을 단시간내에 양산할 수 있도록 한 가구서랍용 안내레일의 제조장치에 관한 것이다.The present invention is installed on a desk or a file box with a drawer in steel or wood furniture to produce a guide rail for furniture drawers for mass production of a guide rail that smoothly operates when opening and closing the drawer in a short time. It is about.

일반적을 가구서랍용 안내레일은 합성수지재로 형성한 것과 쉽게 양산이 될수 있는 L자형강이나 ㄷ자형의 형강등을 이용하고 있다.In general, the guide rail for furniture drawers is made of synthetic resin material and L-shaped or c-shaped steel that can be easily mass-produced.

그런데 합성수지재로 된 것은 금형에 의하 양산이 가능하고 그 형태를 여러형태로 다양하게 할 수 있으며 제작단가가 저렴하게 되는 이점이 있으나 강도상의 문제로 서랍체에 설치하였을때 서랍에 내장된 물건과 서랍무게가 합쳐진 하중에 의하여 쉽게 파손되었으므로 장기간동안 사용할 수 없다는 결점이 있다.However, the synthetic resin material can be mass-produced by a mold, and its shape can be varied in various forms, and the manufacturing cost can be reduced. There is a drawback that it cannot be used for a long time because it is easily broken by the combined load.

그리고 L자형이나 ㄷ자형의 형강으로 된 것은 두께가 두꺼워서 그 형태를 다양하게 양산하는 것이 난이하여 서랍체를 열고 닫을때 그 작동이 원활하게 될 수 없다는 문제점이 있다.In addition, the L-shaped or c-shaped steel is thick, so that it is difficult to mass-produce the shape in various ways, and thus there is a problem that its operation cannot be smoothly opened and closed.

본 발명은 상기와 같은 종래의 문제점을 감안하여 소정 두께의 철판을 일정한 폭으로 절단하여 얻은 철편을 본 발명의 제조장치로서 가구서랍용 안내레일을 사용하기에 알맞은 형태로 성형된 형강이 연속하여 양산 가능케 한 것이다.The present invention in consideration of the above-described conventional problems, the steel sheet obtained by cutting the iron plate of a predetermined thickness in a predetermined width as a manufacturing device of the present invention is continuously mass-produced shaped steel in a form suitable for using the guide rail for furniture drawers It is possible.

종래에도 안내레일을 프레스 가공으로 성형하기는 하였으나 이들은 그 대부분이 일정한 길이와 폭으로 절단된 철편을 프레스로서 성형시켰기 때문에 안내레일의 길이가 일정길이로 한정된다는 문제점이 있으므로 안내레일을 일정치수로 한정시켜야했고 또한 안내레일의 길이가 주문자에 의하여 변형될대 이를 성형하기 위한 금형을 자주 교체시켜야하는 번거로움이 있었던 것이다.Conventionally, the guide rail was formed by press working, but since most of them were formed by pressing a piece of iron cut to a certain length and width, the length of the guide rail was limited to a certain length, so the guide rail was limited to a certain dimension. In addition, when the length of the guide rail is deformed by the user, it is a hassle to frequently change the mold for forming the guide rail.

본 발명에서 필요로 하는 가구 서랍용 안내레일은 첨부도면 제9도에서 표시한 바와 같이 가구(4)의 내측벽면에 고정되는 고정편(1)과 서랍체(5)의 외측벽면에 후단부가 고정되는 이동편(2)을 생산하기 위한 장치로서 고정편(1)과 이동편(2)은 통상적으로 그 두께가 1.8mm 이상의 것을 사용하는데 이들은 첨부도면 제8도, 제10도에서와 같이 고정편(1)은 절단부의 단면이 "

모터(M)에 의하여 동력이 전달되는 주동기어(11)의 상부 양측에 주동기어(11)와 각각 교합되어 회동방향이 동일한 종동기어(12)(12')들의 상부로 동력전달기어(13)(14)가 각각 교합되어 있다. 일측 동력전달기어(13)는 하부로울러용기어(15a)(15b)를 회동시켜 하부로울러용기어(15b)가 동력전달기어(13a)에 동력을 전달하여 하부로울러용기어(15c)를 연동시킴과 동시에 동력전달기어(13b)에 동력을 전달하면서 하부로울러용기어(15c), 동력전달기어(13c)하부로울러용기어(15e)를 회동시키도록 되어 있고 동력전달기어(13b)는 필요에 따라 하부로울러용기어(15d)(15c)사이에서 이완될 수 있게 구성되어 있다.The power transmission gears 13 interlock with the main gears 11 on both sides of the main gear 11 to which power is transmitted by the motor M, respectively, to the top of the driven gears 12 and 12 'having the same rotational direction. (14) are respectively occluded. One side of the power transmission gear 13 rotates the lower roller gears 15a and 15b so that the lower roller gear 15b transmits power to the power transmission gear 13a to interlock the lower roller gear 15c. At the same time, while transmitting power to the power transmission gear 13b, the lower roller gear 15c and the power transmission gear 13c lower roller gear 15e are rotated, and the power transmission gear 13b as necessary. It is comprised so that it may be relaxed between the lower roller gears 15d and 15c.

그리고 종동기어(12')에 의하여 회동되는 타측의 동력전달기어(14)는 하부로울러용기어(16a)(16b)를 회동시키게 되고 하부로울러용기어(16b)의 회동에 의하여 동력전달기어(14a), 하부로우러용기어(16c), 동력전달기어(14b), 하부로울러용기어(16d)를 연동시키도록 구성되어 있다.The other power transmission gear 14 rotated by the driven gear 12 'rotates the lower roller gear gears 16a and 16b, and the power transmission gear 14a is rotated by the lower roller gear 16b. ), The lower roller gear 16c, the power transmission gear 14b, and the lower roller gear 16d are interlocked with each other.

따라서 회동방향이 동일한 하부로울러용기어(15e)(15d)(15c)(15b)(15a)(16a)(16b)(16c)(16d)들은 그 상부에 교합디어 있는 상부로울러용기어(17e)(17d)(17c)(17d)(17a)(18a)(18b)(18c)(18c)(18d)들을 회동시키도록되어 있으며 이들 상하부로울러용기어들에 의하여 상부로울러(17e')(17d')(17c')(17b')(17a')(18a')(18b')(18c')(18d')와 하부로울러(15e')(15d')(15c')(15b')(15a')(16a')(16b')(16c')(16d')들이 회동되는 것이다. 모터(M)에 동력을 인가시킨 다음 일정한 폭으로 전달되어 두루마리형으로 권회된 철편(10)을 제1공정부(A)의 구동로울러(6)(6')사이의 간극을 통과시켜 철편(10)이 수평상태로 펴진 상태에서 제2공정부(B)로 진입시키면 철편(10)이 제2공정부(B)의 상, 하부로울러 (17e')(17d')(17c')(15e')(15d')(15c') 사이의 간극을 통과하면서 상부로울러 (17e')(17d')(17c')에 형성된 돌부(b)와 하부로울러(15e')(15d')(15c')의 요부(b')에 의하면 철편(10)의 양단부가 절곡되어 첨부도면 제3(a)도와 같이 그 단면이 "
