본 고안은 L형 앵글을 90°(또는 소정각도)로 절곡할 때 쓰이는 앵글용 벤딩기에 관한 것으로서 특히, 유압실린더의 높은 압력을 이용하여 V형 단부를 갖는 램을 서서히 이송시켜 앵글을 기계적으로 절곡시킬 수 있도록 고안된 것이다.The present invention relates to an angle bending machine used when bending an L-shaped angle to 90 ° (or a predetermined angle). In particular, the angle is mechanically bent by slowly transferring a ram having a V-shaped end by using a high pressure of a hydraulic cylinder. It is designed to be.
L형 앵글의 벤딩작업은 제1a도와 같은 소정 각도의 V홈(H)이 마련된 앵글(A)을 제1b도와 같이 절곡시키는 것이다.The bending operation of the L-type angle is to bend the angle A provided with the V groove H at a predetermined angle as shown in FIG. 1A as shown in FIG. 1B.
이렇게 벤딩작업함에 있어서 종래에는 앵글(A)의 절곡부(B)부위를 벌겋게 가열하고 햄머등을 사용 적당히 두둘겨 주무로써 절곡시키는 수작업에 의존하여 왔던 것이다.In the bending work, conventionally, the bending portion B of the angle A has been heated to a large extent, and it has been relied on the manual work of bending by using a hammer or the like moderately.
따라서 앵글을 가열 및 두들겨주는 시간이 매우 길게 소요되고 많은 인력은 물론 작업자의 위험부담 및 쉬 피로현상등 작업능률이 떨어질 수 밖에 없었던 것이다.Therefore, it takes a very long time to heat and beat the angle and the work efficiency, such as the risk of workers and the fatigue of the worker, as well as a lot of manpower was deteriorated.
뿐만 아니라 적당히 두둘겨 작업하므로 벤딩부위의 모양이 반듯하지 못하고 정밀성이 떨어지는 문제점도 있었던 것이다.In addition, since the work is moderately beaten, there was a problem that the shape of the bending part was not smooth and the precision was inferior.
본 고안은 이러한 문제점을 해결하고자 안출된 것으로서 앵글의 벤딩작업을 수작업에 의존하지 않고 기계적으로 신속하고 정밀하게 작업할 수 있게하여 작업능률의 극대화를 기여하고자 그 뜻이 있는 바 유압실린더의 높은 압력을 기계적으로 가압, 앵글을 절곡시킬 수있도록 구성한 것이다.The present invention was devised to solve this problem, and it is intended to contribute to the maximization of work efficiency by enabling mechanical bending quickly and precisely without relying on angle bending work. It is configured to be mechanically pressurized and angled.
이를 첨부된 도면에 의거하여 더욱 상세하게 설명하면 다음과 같다.When described in more detail on the basis of the accompanying drawings as follows.
본 고안 벤딩기는 제2도와 같이, 테이블(1)상면에 V형 가압두부(3)를 갖는 램(2)을 슬라이드 이동 가능하게 설치하여 그 후단면(4)이 전진용 유압실린더(5)의 피스톤 롯드(5')단부에 인접되게 함과 동시에 그 아래에 일체로 연장된 꼬리부(2')는 반대방향으로 설치된 후진용 유압실린더(6)의 피스톤 롯드(6')단부에 인접되게 하고, 상기 가압두부(3)전방으로는 소정간격을 두고 V홈(8)을 갖는 압력받이판(9)을 고착시키는 한편, 그 좌우 측면에는 높이가 다른 다단턱(11)과 등간격의 걸침홈(12)들이 위아래 형성된 앵글 받침판(10)을 지지판(13)내측의 핀(14)에 걸어둘 수 있게 하여된 구성으로서 부속장치로는 상기 2개의 단행정 유압실린더(5,6)를 동작시키기 위한 유압펌프 및 유압전환밸브(도시생략)등이 사용된다.The bending machine of the present invention, as shown in Fig. 2, is provided with a ram 2 having a V-type pressurized head 3 on the upper surface of the table 1 so as to be slidable so that the rear end face 4 of the bending hydraulic cylinder 5 is moved forward. While adjacent to the end of the piston rod (5 '), the tail (2') integrally extending below it is adjacent to the end of the piston rod (6 ') of the reverse hydraulic cylinder (6) installed in the opposite direction While fixing the pressure receiving plate 9 having the V groove 8 at a predetermined interval in front of the pressurized head 3, the left and right sides of the stepped grooves at equal intervals with the multi-stage jaws 11 having different heights. (12) is configured to be able to hang the angle support plate 10 formed up and down on the pin 14 inside the support plate 13 as an accessory to operate the two single-stroke hydraulic cylinder (5, 6) Hydraulic pump and hydraulic switching valve (not shown) are used.
상기 본 고안의 작용 설명에 앞서 초기위치를 말해두면 램(2)의 가압두부(3)와 압력받이판(9)의 전면간 간격은 절곡시키려는 앵글(A)의 두께를 감안하여 최소 간격으로 된다.In the initial position prior to explaining the operation of the present invention, the interval between the pressing head 3 of the ram 2 and the front surface of the pressure receiving plate 9 becomes a minimum interval in consideration of the thickness of the angle A to be bent. .
이러한 본 고안에 의하여 제1a도와 같은 앵글(A)를 절곡하려면 먼저 앵글(A)의 수직한 외면을 압력받이판(9)의 전면에 밀착시켜 그 하단 가장자리가 좌우측 앵글받침판(10)의 다단턱(11)에 받히도록 하여 제3도와 같이 놓인다.In order to bend the angle A as shown in FIG. 1a according to the present invention, the vertical outer surface of the angle A is first brought into close contact with the front surface of the pressure receiving plate 9, and the bottom edge thereof is the multi-stage of the left and right angle support plates 10. It is supported by (11) and placed as in Figure 3.
여기서 앵글(A)의 크기에 따라 앵글받침판(10)의 높이 조절이 필요한 것인데 이는 지지판(13)내측의 핀(14)에 걸치게 되는 걸침홈(12)을 선정함으로써 결정되는 다단턱(11)에 의하여 어느정도 조절 가능한 것이다.Here, it is necessary to adjust the height of the angle support plate 10 according to the size of the angle (A), which is determined by selecting the latching grooves 12 to be applied to the pin 14 inside the support plate 13, the multistage step 11 is determined. By some control.
이와같은 상태에서 전진용 유압실린더(5)를 동작시키면 그 피스톤 롯드(5')에 의하여 램(2)이 전진한다.In this state, when the forward hydraulic cylinder 5 is operated, the ram 2 is advanced by the piston rod 5 '.
램(2)이 전진하면 제4도와 같이 램(2)의 V형 가압단부(3)끝선 부분이 앵글(A)의 절곡부(B)에 선접되면서 그 부위를 집중적으로 가압하게 된다.When the ram 2 is advanced, the end portion of the V-type pressing end 3 of the ram 2 is in contact with the bent portion B of the angle A as shown in FIG. 4 to concentrate the pressure.
그러므로 상대적으로 약한 절곡부(B)가 먼저 굽어지면서 앵글(A)은 램(2)의 가압단부(3)와 압력받이판(9)의 V홈(8) 형상을 따라 제4b도와 같이 벤딩되는 것이다.Therefore, while the relatively weak bend B is bent first, the angle A is bent as shown in FIG. 4B along the shape of the V groove 8 of the pressure end 3 of the ram 2 and the pressure receiving plate 9. will be.
벤딩이 끝나면 도시되지 않은 유압전환 밸브를 조작하여 전진용 유압실린더(5)의 유압을 차단함과 동시에 후진용 유압실린더(6)에 유압을 인가하여 주면 그 피스톤 롯드(6')에 의하여 꼬리부(2')와 함께 램(2)이 후진된다.After bending, the hydraulic switching valve (not shown) is operated to shut off the hydraulic pressure of the forward hydraulic cylinder (5) and to apply hydraulic pressure to the reverse hydraulic cylinder (6). Ram 2 is retracted with 2 '.
이때 유압실린더(6)의 피스톤 롯드(6')는 후진하는 램(2)의 후단면(4)에 밀리므로 수동적으로 복귀된다.At this time, the piston rod 6 ′ of the hydraulic cylinder 6 is pushed back to the rear end face 4 of the ram 2 to be retracted and is manually returned.
이상에서 설명한 바와 같이 본 고안 앵글용 벤딩기에 의하면 앵글의 벤딩작업은 수작업에 의하지 않고 기계적으로 자동 처리함으로써 적은 인력으로 단시간 내에 작업을 완료할 수 있어 작업능률의 극대화를 이룩할 수 있게된 매우 효과적인 고안이라 하겠다.As described above, according to the angle bending machine of the present invention, the bending work of the angle is a very effective design that can maximize the work efficiency by completing the work in a short time by mechanically and automatically processing the angle without manual work. would.
