본 고안은 압입지그의 에어쿠션장치에 관한 것으로, 유압프레스의 하단에 부설하용하므로서 공정별 각 지그마다 별도의 쿠션용 탄발스프링을 사용할 필요가 없도록하여 지그구조의 단순화를 기한 것이다.The present invention relates to the air cushioning device of the press-fit jig, it is intended to simplify the jig structure by eliminating the need for using a separate cushioning ball spring for each jig by laying on the bottom of the hydraulic press.
종래의 쿠션장치는 탄발스프링을 이용한 것으로, 첨부도면 제1(a)도에서 보는 바와같이 하단 플레이트(15)의 하부 중앙에 인장봉(15a)을 나사조립하고, 그 상단부에 완충플레이트(15b)를 끼워서 누름봉(13)의 하단부와 밀접되게하여 탄발스프링(a)에 의해 탄발지지되게 구성한 것이었다. 또한 제1(b)도에서와 같이 스트리퍼(16)를 스토파(16a)의 상부에 밀접되도록 탄발스프링(a)으로 탄지시켜서된 구성인것으로, 상기 한 바와같이 각 지그마다 별도의 탄발스프링이 사용되는 것이므로 지그구조가 복잡하게되는 것이었다.The conventional cushioning device uses a carbon spring, and as shown in the attached drawing (a) of FIG. 1, a tension bar 15a is screwed into the lower center of the lower plate 15, and a buffer plate 15b is provided at the upper end thereof. Was inserted into close contact with the lower end of the pressing rod 13 was configured to be supported by the bullet spring (a). In addition, as shown in FIG. 1 (b), the stripper 16 is held by the carbon spring a so as to be in close contact with the top of the stopper 16a. As described above, a separate carbon spring is provided for each jig. Jig structure was complicated because it is used.
본 고안은 상기한 바와같이 문제점을 해결하여 압입지그의 유압프레스 하부에 부설하여 모든 공정별 압입 지그의 쿠션장치로서 공용토록하여 지그구조를 단순화함에 그 목적이 있는 것으로, 첨부도면에 의거 상세히 설명하면 다음과 같다. 즉, 유압프레스의 프레임(14a)하부에 볼트(2)로서 고정시킨 튜브(1)의 하단에 링(3)을 내설하여서 헤드카바(4)로 고정볼트(5)에 의해 튜브(1)에 조립 고정하고, 헤드카바(4)의 일측에는 에어 유통구(4a)를 형성하여 튜브(1)의 에어유통공(1a)와 연통되게하며, 튜브(1)의 내부중앙에 위치되어 헤드카바(4)를 관통슬라이딩 케한 로드(6)에 피스톤(7)을 설하여 그 상승한도를 로드(6)의 하단에 체결시킨 너트(8)와 와셔(9) 및 로드(6) 상부의 너트(10)와 스프링와셔(11)로서 제한토록 하고, 튜브(1)의 최상단부에는 공기압의 누출을 방지하는 패킹(12)을 접착하여 그 일측의 "+"자형 절결부로 관통되어 들어온 누름봉(13)의 하단이 피스톤(7)의 상면에 접촉되도록 하고, 튜브(1)의 일측면에 에어유통공(1b)을 형성하여서 되는 압입지그의 에어쿠션장치인 것이다.The present invention aims to simplify the jig structure by solving the problem as described above and laying it under the hydraulic press lower portion of the press-fit jig to share it as a cushioning device of the press-fit jig for every process. As follows. That is, the ring 3 is internally installed at the lower end of the tube 1 fixed to the lower part of the frame 14a of the hydraulic press as the bolt 2, and the head cover 4 is attached to the tube 1 by the fixing bolt 5. It is assembled and fixed, one side of the head cover 4 to form an air distribution port (4a) to communicate with the air distribution hole (1a) of the tube (1), located in the inner center of the tube (1) 4) A piston (7) is installed on the rod (6) through the sliding slide, and the nut (8), washer (9) and nut (10) on the rod (6) are fastened to the lower end of the rod (6). And a spring washer 11, and a push rod 13 penetrated through a "+" shaped cutout on one side by adhering a packing 12 to prevent the leakage of air pressure at the upper end of the tube 1. It is an air cushioning device of the press-fit jig so that the lower end of the) is in contact with the upper surface of the piston (7), and the air distribution hole (1b) is formed on one side of the tube (1).
첨부도면중 미설명부호 4b는 헤드카바패킹, 7a는 피스톤패킹, 14는 유압프레스 테이블, 14a는 유압프레스 프레입, 15는 하단플레이트, 16은 스트리퍼, 16는 스토파, 17은 압입패드, 18은 상단플레이트, 18a는 승강안내봉, 19는 유압프레스 램, 20은 조립제품을 각각 나타내는 것이다.In the drawings, 4b is head cover packing, 7a is piston packing, 14 is hydraulic press table, 14a is hydraulic press fill, 15 is lower plate, 16 is stripper, 16 is stopper, 17 is press-fit pad, 18 Is the upper plate, 18a is the lifting guide bar, 19 is the hydraulic press ram, and 20 is the assembled product.
본 고안의 작동상태를 설명하면 먼저 제2도에서와 같이 지그의 압입작동이 시작되기전 튜브(1)내의 피스톤(7)이 상승되어있는 상태에서 헤드카바(4)의 에어유통구(4a)를 통하여 공기공급원(A)으로 부터 공기압축기(B) 및 속도제어기(C)를 거쳐튜브(1)내로 유입된 공기압이 피스톤(7)의 하측공간부에 충만케되어 피스톤(7)은 위쪽으로 받쳐지는 공기압을 받게되는 것이다. 이런상태에서 제3도에서와 같이 유압프레스램(19)이 하강하여 상단 플레이트(18)를 하강시켜 주게되면 압입패드(17)가 함께 하강되면서 스트리퍼(16)를 소정의 스토로크 위치까지 하강시켜주게 되어 제품(20)의 압입이 완료되는 동시에 하강되는 스트리퍼(16)에 조립되어 있는 누름봉(13)이 함께 하강되어 피스톤(7)을 하강시켜 주게되는 데 이때 피스톤(7)은 하부에서 공기압을 받고 있으나 그 하강력이 더 크므로 피스톤(7)은 공기압의 저항에 의한 완충력을 받으면서 계속 하강케된다. 이때의 공기압은 다시 헤드카바(4)의 에어유통구(4a)를 통하여 안전밸브(D)에 의해 머플러(E)로 배기되므로 피스톤(7)의 계속적인 하강이 가능하게되는 것이다.Referring to the operating state of the present invention, first, as shown in FIG. 2, the air flow port 4a of the head cover 4 in the state where the piston 7 in the tube 1 is raised before the press-in operation of the jig starts. Through the air compressor (B) and the speed controller (C) from the air source (A) through the air pressure introduced into the tube (1) is filled in the lower space of the piston (7) so that the piston (7) upwards You will be supported by air pressure. In this state, as shown in FIG. 3, when the hydraulic press ram 19 descends to lower the upper plate 18, the press-fit pad 17 descends together and lowers the stripper 16 to a predetermined stroke position. When the press-fitting of the product 20 is completed and the push rod 13 assembled in the stripper 16 is lowered together, the piston 7 is lowered together, and the piston 7 lowers the air pressure at the bottom. But the lowering force is greater, so the piston (7) continues to descend while receiving the buffer force by the resistance of the air pressure. At this time, the air pressure is exhausted to the muffler (E) by the safety valve (D) again through the air flow port (4a) of the head cover (4) is to allow the continuous lowering of the piston (7).
또한 피스톤(7)이 계속 하강되면서 튜브(1)내의 피스톤(7) 상측 공간부가 진공상태가 되지 않도록 튜브(1)의 일측면에 형성시킨 에어유통공(1b)을 통하여 대기의 공기가 유입케되는 것이다.In addition, as the piston 7 continues to descend, atmospheric air flows in through the air flow hole 1b formed on one side of the tube 1 so that the upper space of the piston 7 in the tube 1 does not become a vacuum state. Will be.
이와같이 압입작동이 완료된후 프레스램(19)이 다시 상승케되면 공기 공급원(A)으로 부터 공기압이 다시 튜브(1)내로 유입케되고 동공기압에 의해 피스톤(7)이 상승되면서 누름봉(13)을 상승시켜 주게되어 제2도의 상태로 원상복귀 시켜 주게되는 것이다.When the pressram 19 is raised again after the press-in operation is completed, the air pressure from the air source A is introduced into the tube 1 again, and the piston 7 is raised by the air pressure to push the rod 13. It will raise and return to the state of the second degree.
본 고안은 상술한 바와같이 작동되어 종래의 탄발스프링을 이용한 쿠션장치와 같은 역활을 하면서 공정별로 연속작동되는 모든 압입지그의 쿠션장치로서 공용화할 수 있게되어 압입지그의 구조를 보다 단순화 시켜 주게되는 것이며, 공정별로 압입지그의 작동을 일률적으로 행하게되어 작업능률의 향상을 기할 수 있는 매우유용한 효과를 제공하여 주는 것이다.The present invention is operated as described above, and can be shared as a cushioning device of all the press-fit jig that is continuously operated by each process while acting as a cushion device using a conventional carbon spring, to simplify the structure of the press-fit jig more. In other words, the operation of the press-fit jig is performed uniformly for each process, which provides a very useful effect for improving the work efficiency.
