본 고안은 L형 앵글을 절단할때 쓰이는 앵글용 절단기에 관한 것으로서 특히, 유압실린더의 높은 압력을 이용하여 두께가 두꺼운 앵글도 단번에 절단할수 있도록 고안된 것이다.The present invention relates to an angle cutter used for cutting L-shaped angles, and in particular, is designed to cut even thick thickness at once using the high pressure of the hydraulic cylinder.
보편적으로 앵글(A)의 절단작업은 그 두께나 폭에 따라 쇠톱, 절단용 회전숫돌 또는 산소 용단토오치등을 사용하여 수작업 하였었으므로 작업속도가 느리고, 절단면이 거칠어 절단면 재가공이 필요하였으며, 인력소모가 과다함과 아울러 작업자가 쉬피로해지는 등 작업능률이 저해되었던 것이다.In general, the cutting work of angle (A) was done by hand using hacksaw, cutting grindstone or oxygen cutting torch, depending on the thickness and width. Excessive consumption and the worker's efficiency was reduced.
본 고안은 위와 같은 수작업에서 탈피하여 작업능률의 향상을 꾀하고자 안출된 것으로서, 테이블상에 <형절단도를 갖는 램을 슬라이드 이동가능하게 설치하고 그 후면에는 유압실린더의 피스톤 롯드 단부가 밀접되게 하며 절단도 전방에는 역시<형 날받이를 만들어 줌으로써 신속하고 정확한 앵글의 절단 작업이 가능하게 한 것인바 첨부된 도면에 의거하여 더욱 상세하게 설명하면 다음과 같다.The present invention was devised to improve the work efficiency by avoiding the above-mentioned manual work. The ram with slide shape is installed on the table so as to be slidable, and the piston rod end of the hydraulic cylinder is closely connected to the rear side. In front of the cutting diagram is also to enable a quick and accurate angle cutting work by making the blade-shaped blade bar in more detail based on the accompanying drawings as follows.
본 고안 앵글용 절단기는 제2도에 도시한 바와같이, 테이블(1)상면 중앙의 이송가이더(2)내부에 커다란 중량물의 램(3)을 슬라이드 이동 가능하게 삽입하여 그 후면의 압판(4)이 전후진용 유압실런더(5,6)의 피스톤롯드(5',6')단면과 서로 반대 방향으로 되게 하고 램(3)의 전면에는 앵글의 내면과 밀착될수 있는 <형절단도(7)를 체결하여 주는 한편, 그 전방으로는 상기 절단도(7)가 엇갈려 일치되면서 앵글의 외면이 밀착될수 있는 <형 날받이(8)과 함께 이의 측방과 후방으로 여유폭을 둔 보조받이(9)를 고착시키며, 이를 좌우측방인 테이블(1)측면에는 높낮이 조절용 앵글받침판(10,10)을 그리고 날받이(8)와 일측 앵글받침판(10)사이에는 전후간격 조절용의 수직한 앵글 지지봉(11)을 각각 설치하여 된 구성으로서 부속장치로는 2개의 단행정 유압실린더(5,6)를 동작시키기 위한 유압펌프 및 유압전환 밸브(도시생략)등이 사용된다.The angle cutting machine of the present invention, as shown in FIG. 2, inserts a large-weight ram 3 into the feed guide 2 in the center of the upper surface of the table 1 so as to be slidable, and the platen 4 at the rear thereof. The cross section of the piston rods 5 'and 6' of the forward and backward hydraulic cylinders 5 and 6 is opposite to each other, and the front surface of the ram 3 can be in close contact with the inner surface of the angle. In the meantime, while the cutting degree (7) in the front and the opposite side of the angle and the outer surface of the angle can be in close contact with the <shaped blade holder (8) with the auxiliary width (9) with the width of the side and the rear It is fixed to the left and right sides of the table (1) side, the height adjustment angle support plate (10,10) and between the blade support (8) and one angle support plate (10) vertical angle support rods (11) for front and rear interval adjustment, respectively. This is a built-in configuration that operates two single-stroke hydraulic cylinders (5, 6) with attached equipment. The hydraulic pump and the hydraulic switching valve (not shown) for Pointing is used.
이와 같은 본 고안 절단기로써 앵글을 절단하려면 먼저 자르려는 앵글(A)의 폭에 따라 이를 <형 날받이(8)에 지지시킬수 있도록 높낮이 조절용 받침판(10,10')과 전후 간격 조절용 지지봉(11)의 조절이 필요할 것이다.In order to cut the angle with the present invention cutter as described above, according to the width of the angle (A) to be cut first of the height adjustment base plate (10,10 ') and the support bar for front and rear interval adjustment (11) to support it Adjustment will be required.
즉, 제3도(a)(b)와 같이, 날받이(8)에 앵글(A)의 절단부(C)외면을 밀착시키고 양측의 받침판(10,10')과 지지봉(11)을 각각의 장공과 조절넛트(부호 생략)로써 조절하여 두면 앵글(A)은 그 가장자리가 받침판(10,10')상단과 지지봉(11)일측부와 접지되어 자연스럽게 지지된다.That is, as shown in FIG. 3 (a) (b), the outer surface of the cut portion C of the angle A is brought into close contact with the blade support 8, and the supporting plates 10, 10 ′ and the supporting rods 11 on both sides are respectively drilled. If the angle (A) is adjusted by the control nut (not shown) and the edge is grounded with the upper side of the support plate (10, 10 ') and one side of the support rod 11 is naturally supported.
이러한 상태에서 전진용 유압실린더(5)를 동작시키면 제4도와 같이 운동하는 그 피스톤 롯드(5')에 의하여 압판(4)과 함께 램(3)이 전진하고 <형 절단도(7)는 날받이(8)에 외면이 밀착된 앵글(A)의 절단부(C)내면으로 밀착된다.In this state, when the forward hydraulic cylinder 5 is operated, the ram 3 moves forward together with the platen 4 by the piston rod 5 'that moves as shown in FIG. The outer surface is in close contact with (8) the inner surface of the cut portion (C) of the angle (A).
(제4도(a) 참조)(See Figure 4 (a))
계속 전진하면 유압실린더(5)의 높은 압력에 의해 앵글(A)은 어느 순간에 전달된다.(제4도(b)참조)If it continues, the angle A is transmitted at any moment by the high pressure of the hydraulic cylinder 5 (refer FIG. 4 (b)).
이때 앵글(A)은 날받이(8)내측에 엇갈려 전진하는 절단도(7)의 진행에 따라 회전 모멘트가 작용하게 되나 그 반대편이 지지봉(11)에 받혀진 것이므로 용이하게 절단되어 지며 절단된 부분인 앵글(A')은 날받이(8)와 여유폭을 두고 설치된 보조받이(9)에 의해 튕겨나갈 염려가 없으므로 안정성이 보장된다.At this time, the angle (A) is rotated in accordance with the progress of the cutting diagram (7) to move forward to the inside of the blade support (8), but the opposite side is supported by the support rod 11 is easily cut and cut Since the angle A 'is not feared to be bounced off by the auxiliary support 9 provided with the blade support 8 and the clearance width, stability is ensured.
제5도는 절단작업을 마친 램(3)의 후진작용도로서 전진용 유압실린더(5)의 유압을 차단함과 동시에 후진용 유압실린더(6)에 유압을 인가하여 주므로써 램(3)의 후진이 가능하고 이미 전진된 유압실린더(5)의 피스톤 롯드(5')는 램(3)의 압판(4)에 의해 수동적으로 복귀되는 것이다.5 is a reverse action diagram of the ram (3) after the cutting operation, the hydraulic pressure of the forward hydraulic cylinder (5) is interrupted and the hydraulic pressure is applied to the reverse hydraulic cylinder (6) to reverse the ram (3) This possible and already advanced piston rod 5 ′ of the hydraulic cylinder 5 is manually returned by the platen 4 of the ram 3.
이러한 과정을 반복함으로써 같은 규격의 앵글 절단작업을 반복 수행하는 것이다.By repeating this process, the same angle cutting operation is repeated.
참고로 본 고안 앵글용 절단기에 단행정 유압실린더(5,6)2개를 사용한 것은 커다란 중량물의 램(3)을 효과적으로 전후진 시킴과 아울러 그 유압실린더를 다른 기기에도 사용할수 있도록 쉽게 분리시킬 의도에서 이며, 2위치의 윱압포트를 갖는 왕복실린더 한개를 사용할수도 있는 것이다.For reference, the use of two single-stroke hydraulic cylinders (5, 6) in the angle cutting machine of the present invention is intended to effectively move the large weight ram (3) back and forth, and to easily separate the hydraulic cylinder for use in other equipment. It is possible to use one reciprocating cylinder with two pressure pin ports.
이상에서 설명한 바와 같이 본 고안에 의하며 비교적 두께가 두꺼운 앵글의 절단작업을 단시간 내에(대략 8초간 정도)행할수 있고, 순간적으로 절단되므로 그 절단면이 깨끗하여 절단면의 재가공이 필요없으며, 인력과 작업자의 피로를 덜수 있어 작업능률의 극대화를 이룩할 수 있는 매우 효과적인 고안인 것이다.As described above, according to the present invention, cutting of relatively thick angles can be performed within a short time (about 8 seconds), and because the cutting is instantaneous, the cutting surface is clean and does not require reworking of the cutting surface. It is a very effective design that can reduce fatigue and maximize work efficiency.
