본 고안은 건축용 철근을 절곡 및 절단을 함에 있어 모우터에 의하여 작동되는 유압펌프가 실린더내의 피스턴을 밀어주고 피스톤선단에 형성된 랙기어는 회동편과 일체로 형성된 기어를 회전시키면 동히에 회동편은 일방향으로 회동되면서 기어의 축과 회동봉 사이에 개재되어 있는 철근을 원하는 각도만큼 절곡시키도록 하였으며 역시 실린더내의 피스턴 일단에 절단칼을 형성하여 절단칼이 하강하면서 철근을 절단할수 있어 건축시에 필수적으로 사용되는 철근을 용이하게 절곡도 시키고 절단토록한 것이다.The present invention is for bending and cutting construction reinforcing bar, the hydraulic pump actuated by the motor pushes the piston in the cylinder, and the rack gear formed at the piston end rotates the gear formed integrally with the rotating piece while the rotating piece is in one direction. Rotating between the shaft of the gear and the rod to bend to the desired angle to bend the reinforcement to form a cutting knife at the end of the piston in the cylinder can also cut the rebar as the cutting knife descends, which is essential for construction The rebar will be easily bent and cut.
종래에는 철근을 절곡하고져 할때 임의의 대판에 고정봉을 형성한 사이로 철근을 삽입한 상태에서 철근의 일단을 잡고 작업하는 사람이 필요한 각도만큼 움직이어 철근을 절곡시키는 것이어서 절곡되는 상태가 불균형으로 되면서도 인위적으로 절곡시키기 때문에 작업능률이 떨어지는 결점이 있을뿐만 아니라 철근을 절단할때는절단칼을 철근위에 올려놓고 해머 또는 도구로 여러번에 결치어 절단칼을 강타하여 절단시키므로 절단하는데 힘의 소요되므로 많은량을 절단할때는 상당한 시간과 힘의 소모가 큰 결점이 있으며 더욱이 정확한 위치에서 철근을 절단하고저 할때는 해머로 절단칼을 강타 하여야하므로 충격에 의하여 절단칼의 위치가 움직이고 상대적으로 사고의 위험성도 높은 것이었다.Conventionally, when the reinforcing bar is to be bent while the rebar is inserted into a certain plate while the reinforcing bar is inserted while the person working holding the one end of the reinforcing bar to bend the reinforcement to the angle required, It not only has the drawback of poor work efficiency because it is artificially bent, but also when cutting the rebar, the cutting knife is placed on the rebar and the hammer or tool is cut several times and the cutting knife is struck and cut. When you use a considerable time and power consumption, there is a drawback, and when cutting the rebar in the correct position, and when you have to hit the cutting knife with a hammer, the position of the cutting knife was moved by the impact and the risk of accident was relatively high.
그러나 본 고안에서는 모우터에 의하여 작동되는 시린더 내의 피스턴을 유압으로 작동시켜 랙기어가 기어를 회동시키고 기어와 일체인 회동편이 일측방향으로 회전할때 기어 축과 회동봉 사이에 삽입되어 있는 철근을 임의의 각도만큼 절곡시키고 또 유압에 의하여 작도되는 절단칼에 의하여 철근을 정확하게 절단시켜 종래와 같이 소음도 없고 많은량을 위험이 없이 절단을 할수 있도록 안출한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.However, in the present invention, the piston in the cylinder operated by the motor is operated hydraulically so that the rack gear rotates the gear and the reinforcing bar inserted between the gear shaft and the rotating rod when the rotating piece integral with the gear rotates in one direction. When bending at an arbitrary angle and cutting the rebars precisely by a cutting knife constructed by hydraulic pressure, it is possible to cut the noise without a large amount without risk as in the prior art. .
대판(1)의 일측에 모우터(2)와 유압펌프(3)를 형성하고 대판(1)의 일측에 보강판(4)을 μ고정하여 수직봉(5)(5')을 각각 형성한 전방으로 기어축(6)의 상측에는 회동편(7)을 고정하고 그 하부에는 기어(8)를 착설하여 랙기어(9)와 접합되어 유압에 의하여 시린더(10)내의 피스턴(11)일측에 형성된 랙기어(9)가 작동되어 회동편(7)이 일측으로 회전되므로 수직봉(5)(5')을 철근이 통과하여 기어축(6)과 회동편(7)의 회동봉(12)사이에 개재되어 있는 철근(13)을 임의 각도만큼 절곡토록 하였으며 대판(1)의 측면에는 또 다른 실린더(14)에 삽설된 피스턴(15)일단에 절단칼(16)을 형성하여 안내홈(17)이 있는 ㄷ형 받침편(18)의 지지편(19)에 초경팁의 받침칼(20)이 있어 임의의 길이에서 철근(13)을 절단토록 한것이며 도면중 미설명 부호 21은 공지의 방법으로 사용되는 조정핸들이다.The motor 2 and the hydraulic pump 3 are formed at one side of the base plate 1, and the vertical rods 5 and 5 'are formed by fixing the reinforcing plate 4 at one side of the base plate 1, respectively. The rotating piece 7 is fixed to the upper side of the gear shaft 6 forward, and the gear 8 is installed at the lower part thereof, and is joined to the rack gear 9 so that one side of the piston 11 in the cylinder 10 by hydraulic pressure. The rack gear (9) formed in the operation is rotated by the rotation piece (7) to one side, so that the rebar passes through the vertical rods (5) (5 '), the rotating rod (12) of the gear shaft (6) and the rotation piece (7) ), The reinforcing bar 13 interposed between the bent by an arbitrary angle and on the side of the base plate 1 to form a cutting knife 16 at one end of the piston 15 inserted in another cylinder 14 to guide grooves ( 17) the support piece 19 of the c-shaped support piece 18 has the support knife 20 of the carbide tip to cut the reinforcing bar 13 at an arbitrary length, and reference numeral 21 in the drawings is a known method. This is a steering wheel used for.
이와 같은 구조의 작용효과를 설명하면 다음과 같다.Referring to the effect of such a structure is as follows.
건축현장에서 많이 사용되는 철근을 알맞게 절곡하고져 할때는 철근(13)을 수직봉(5)(5')사이로 관통하여 기어축(6)과 회동봉(12)까지 통과한 후 모우터(2)에 의하여 유압펌프(3)를 공지의 방법과 같이 작용하여 유압호스를 통하여 시린더(10)내의 피스턴(11)을 밀어주면 피스턴(11)일단에 고정된 랙기어(9)가 전방으로 진행하면서 기어(8)를 랙기어(9)의 진행방향으로 진행시켜 기어축(6)에 고정된 회동편(7)이 전방으로 회전하면서 회동봉(12)이 철근(13)을 밀면서 회전하여 철근(13)은 기어축(6)을 중심으로 하여 절곡이 되게한 효과이다.In order to bend the reinforcing steel rods that are frequently used in construction sites, the rebar 13 passes between the vertical rods 5 and 5 'and passes through the gear shaft 6 and the rotating rod 12 to the motor 2. By operating the hydraulic pump 3 in a manner known in the art to push the piston 11 in the cylinder 10 through the hydraulic hose, the rack gear 9 fixed to the end of the piston 11 proceeds to the front gear (8) advances in the advancing direction of the rack gear (9), while the rotating piece (7) fixed to the gear shaft (6) rotates forward while the rotating rod (12) pushes the reinforcing bar (13) to rotate the reinforcing bar (13). ) Is an effect that is bent around the gear shaft (6).
따라서 원하는 절곡상태에서 전원을 차단하면 선택된 각도에서 절곡된 철근을 얻게 되는 것이다.Therefore, if the power is cut off in the desired bending state, the rebar is bent at the selected angle.
그러고 철근(13)을 절단하고져 할때는 대판(1)의 일측에 형성된 시린더(14)내의 피스턴(15)이 하강하면서 절단칼(16)이 철근(13)에 서서히 압압되면서 절단되는 것을 촉진시키 위하여 지지편(19)의 안내공(17)일측벽에 고정된 초경팁의 절단칼(20)이 철근(13)의 하부에서 절단되는 것을 지지하여 철근의 절단효과를 소음없이 촉진시켜 주는 것이다.Then, when the rebar 13 is to be cut, the piston 15 in the cylinder 14 formed on one side of the base plate 1 descends while the cutting knife 16 is pressed against the reinforcing bars 13 to accelerate the cutting. The cutting knife 20 of the cemented carbide tip fixed to one side wall of the guide hole 17 of the support piece 19 supports to be cut from the lower part of the reinforcing bar 13 to promote the cutting effect of the reinforcing bar without noise.
더욱이 초경팁으로 형성된 절단칼은 견고하여 수명이 연장되게한 것이다.Moreover, the cutting knife formed of cemented carbide tips is firm and has a long life.
따라서 본 고안은 한장소에서 철근을 원하는 각도로 절곡하고 또 종래와 같이 소음이 없이 안전하게 철근을 절단할 수 있도록한 본 고안은 일석이조의 효과를 가지는 것이다.Therefore, the present invention is to bend the reinforcing bar at a desired angle in one place, and the present invention to be able to cut the reinforcing bar safely without noise as in the prior art has the effect of two stone two.
