Description

파이프 벤딩기{PIPE BENDING MACHINE}Pipe Bending Machine {PIPE BENDING MACHINE}

본 발명은 각종 배관작업에 사용되는 금속제 파이프를 배관에 필요한 각도로 굽히는데 사용하는 파이프 벤딩기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe bending machine used to bend metal pipes used for various piping operations at angles necessary for piping.

일반적으로 파이프의 벤딩작업에는 수동기구를 사용하는 방법과 전동기구를 사용하는 방법이 있다. 수동기구는 중량이 가벼운 휴대형으로 이동 및 본관이 용이하고, 좁은 장소에서도 편리하게 작업을 할 수 있으나 대체로 파이프의 직경이 10~15mm로 작거나 강도가 약한 알루미늄제 파이프나 동파이프를 굽히는데 사용하는 것이고 강관파이프나 직경이 15~80mm되는 굵은 파이프는 굽히는데 많은 힘이 들므로 대한민국 등록특허 제10-0406323호와 같은 전용 파이프 벤딩기가 사용된다.In general, the bending of the pipe is a method of using a manual mechanism and a method using an electric mechanism. The manual mechanism is light and portable, so it is easy to move and maintain the main building and can work conveniently even in narrow places. However, it is generally used to bend aluminum pipes or copper pipes with a small diameter of 10 to 15 mm or weak strength. Steel pipe pipes or thick pipes having a diameter of 15 to 80 mm take a lot of power to bend, so a dedicated pipe bending machine such as Korean Patent No. 10-0406323 is used.

그러나 상기 벤딩기는 성형롤러에 종동 베벨기어가 부착되어서 구동축의 베벨기기어와 결합하는 구성으로 구동장치가 구성되어 있고 성형롤러 옆에 별도로 지지롤러가 설치되어 그 사이에 파이프를 개입하여 성형롤러를 회전시키면 성형롤러에 부착된 압착기구로 파이프를 가압하여 파이프를 벤딩하게 되므로 구동장치를 회 전시키는데 힘이 많이 드는 불편이 있었다.However, the bending machine has a driving device in which the driven bevel gear is attached to the forming roller and is coupled to the bevel gear of the drive shaft, and a supporting roller is installed next to the forming roller to rotate the forming roller through a pipe therebetween. Since the pipe is bent by pressurizing the pipe with a pressing mechanism attached to the molding roller, it is inconvenient to take a lot of effort to rotate the driving device.

본 발명은 상기 문제를 해결하기 위해 안출된 것으로서, 비교적 적은 힘으로 성형롤러와 벤딩안내구를 작동시킬 수 있도록 된 파이프 벤딩기를 제공하는데 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a pipe bending machine capable of operating a forming roller and a bending guide with a relatively small force.

본 발명은 워엄나사에 결합하는 워엄휠을 구동시켜서 워엄휠에 결합된 구동축을 일방향으로 회전시키고 구동축에 성형롤러를 부착하고 성형롤러 외측에 벤딩안내구를 결부시켜서 성형롤러를 구동시키는 워엄휠과 같이 벤딩안내구를 작동시키고 벤딩되는 파이프가 파이프 안내구에 적재되어 공급되게 함으로써 벤딩이 용이하고 정밀한 벤딩이 이루어지도록 한 것이다.The present invention rotates the drive shaft coupled to the worm wheel in one direction by driving the worm wheel coupled to the worm screw, attaching the forming roller to the drive shaft, and attaching the bending guide to the outer side of the forming roller, such as a worm wheel for driving the forming roller The bending guide is operated and the pipe being bent is supplied to the pipe guide so that the bending is easy and precise bending is achieved.

이와 같이 된 본 발명은 회전판(510)에 장치된 걸림편(513)을 워엄휠(600) 중심축관(610)에 형성된 고정돌기(610a)에 접촉시킨 후 안내부(20)에 장치된 파이프안내구(300)의 파이프안내홈(320)과 벤딩안내구(530)의 파이프안내홈(530b) 사이에 걸쳐지도록 파이프를 장치하고 구동축(400)을 벤딩 방향으로 회전시키면 벤딩안 내구(530)가 성형롤러(420) 외주를 공전하면서 파이프의 일단을 밀어서 성형롤러(420)에 밀착시키므로 파이프가 필요한 각도로 벤딩되게 되고 파이프가 벤딩되는 상태를 보아 필요한 각도로 벤딩이 되면 구동축(400)의 회전을 중지시키고 걸림편(513)을 워엄휠 중심축관의 고정돌기(610a)에서 분리시키면 회전판(510)이 복원되는데 따라 벤딩안내구(530)가 복원되므로 벤딩된 파이프를 인출하여 사용할 수 있다.According to the present invention as described above, the engaging piece 513 provided on the rotating plate 510 is brought into contact with the fixing protrusion 610a formed on the worm wheel 600, the central shaft tube 610, and then guides the pipe installed in the guide 20. When the pipe is installed so as to span between the pipe guide groove 320 of the sphere 300 and the pipe guide groove 530b of the bending guide 530 and the drive shaft 400 is rotated in the bending direction, the bending inside durability 530 is While rotating the outer circumference of the forming roller 420, one end of the pipe is pushed into close contact with the forming roller 420, so that the pipe is bent at a necessary angle, and when the pipe is bent at a necessary angle, the rotation of the driving shaft 400 is stopped. When the stopping piece 513 is separated from the fixing protrusion 610a of the worm wheel central shaft tube, the rotating plate 510 is restored, so that the bending guide 530 is restored, so that the bent pipe can be used by drawing out the bent pipe.

한편, 걸림편(513)은 그 배면부가 개방부 울타리에 장치되어 있는 작동봉(512)의 요입홈(512a)에 접촉되어 있는 상태에서 작동봉을 시계방향으로 회전시킴에 따라 작동봉의 외면이 걸림편의 배면을 가압하여 내측면의 마찰돌기(513a)가 워엄휠(600)의 중심축관(610) 외면에 형성된 고정돌기(610a)에 접촉되고 워엄휠이 회전하는 방향으로 작동하는 힘과 결합하여 고정돌기의 단턱(610b)과 걸림편(513)의 마찰돌기(513a)가 결합된 상태를 유지하게 되고 그 상태가 지속되므로 회전판(510)과 워엄휠(600)이 결합된 상태가 되기 때문에 구동축이 회전할 때 회전판이 같이 회전하게 되고 회전판에 결합된 벤딩안내구(530)가 구동축을 중심으로 공전되어 파이프 벤딩이 이루어지며 벤딩이 완료된 후 구동축의 회전을 중지시키고 걸림편의 배면부에 장치되어 있는 작동봉을 반대로 회전시키면 작동봉의 요입홈(512a)에 걸림편의 배면이 함장되게 되므로 걸림편의 상단부가 코일스프링(515)의 탄력을 받아 워엄휠의 고정돌기에서 이완되어 구동축과 분리되고 이와 동시에 구동축에 끼워져 있는 회전판은 자체 중량에 의하여 원위치로 복귀하게 되므로 벤딩안내구(530)가 원위치하여 다음 동작에 대비하게 되는 것이다.On the other hand, the locking piece 513 is caught by the outer surface of the operating rod by rotating the operating rod clockwise in the state that the back portion is in contact with the recess groove 512a of the operating rod 512 is installed in the opening fence. By pressing the rear side of the convenience, the friction protrusion 513a on the inner side is fixed to the fixing protrusion 610a formed on the outer surface of the central shaft tube 610 of the worm wheel 600 and coupled with the force acting in the direction in which the worm wheel rotates. Since the stepped jaw 610b of the protrusion and the friction protrusion 513a of the engaging piece 513 are maintained in a coupled state, and the state continues, the rotating plate 510 and the worm wheel 600 are coupled to the driving shaft. When rotating, the rotating plate rotates together, and the bending guide 530 coupled to the rotating plate revolves around the drive shaft to bend the pipe, and stops the rotation of the driving shaft after the bending is completed. Oppose Rotating to the back of the engaging piece in the recessed groove (512a) of the operating rod, so that the upper end of the engaging piece is received by the elastic spring of the coil spring 515 is relaxed from the fixed projection of the worm wheel and separated from the drive shaft and at the same time the rotary plate fitted to the drive shaft Since the return to its original position by its own weight, the bending guide 530 is to prepare for the next operation.

또, 본 발명은 벤딩되는 파이프가 파이프안내구(300)에 적재되어 벤딩부로 공급되므로 벤딩에 대응하여 슬라이드 되면서 공급되므로 적은 저항으로 벤딩이 이루어지는 효과가 있고, 파이프안내구(300)와 성형롤러(420)와 벤딩안내구(530)는 삽탈이 가능하여 파이프 규격에 맞도록 만든 규격품을 선택할 수 있어서 다양한 규격의 파이프 벤딩에 대응할 수 있는 이점이 있으며 워엄나사봉(800)은 수동 공구 또는 모터로 구동시킬 수 있으므로 필요에 따라 선택적으로 활용할 수 있는 이점이 있다.In addition, the present invention has the effect that the pipe is bent with a small resistance because the pipe to be bent to be supplied to the bending portion is loaded on the pipe guide 300 is supplied to the bending portion, the pipe guide 300 and the forming roller ( 420 and the bending guide 530 can be inserted and detached to select a standard product made to meet the pipe standard, there is an advantage that can correspond to the pipe bending of various standards and the worm screw rod 800 is driven by a manual tool or a motor Because it can be made, there is an advantage that can be selectively utilized as needed.
