무 맨드렐 파이프 벤딩기의 파이프 고정장치{A fixing device of the pipe bender without mandrel}  A fixing device of the pipe bender without mandrel}

본 발명은 무 맨드렐 파이프 벤딩기에 삽입되는 벤딩용 파이프를 고정하는 파이프 고정장치에 관한 것이다.  The present invention relates to a pipe fixing device for fixing a pipe for bending to be inserted into the no mandrel pipe bending machine.

본 발명은 본 출원인이 선출원한 무 맨드렐 파이프벤딩기(10-2007-0031246)에 장착된 구속롤러를 벤딩용 파이프 고정대와 고정대 지지판, 고정대 몸체 및 조종간을 결합한 파이프 고장장치로 개선한 것에 관한 것이다.  The present invention relates to an improvement of a restraint roller mounted on the mandrel-free mandrel pipe bending machine (10-2007-0031246) by the present applicant with a pipe failure device combining a pipe holder for bending and a support plate, a holder body, and a steering wheel.

본 발명은 무 맨드렐 파이프 벤딩기의 파이프 고정장치에 관한 것으로, 보다 상세하게는 파이프 벤딩기에 삽입되는 벤딩용 파이프를 고정하되 파이프의 직경에 따라 교체가 용이하고 각도를 조절할 수 있는 파이프 고정장치에 관한 것이다.  The present invention relates to a pipe fixing device of the non-mandrel pipe bending machine, and more particularly to a pipe fixing device for fixing the bending pipe inserted into the pipe bending machine can be easily replaced according to the diameter of the pipe and the angle can be adjusted. will be.

종래에도 각종 파이프를 절곡하는 벤딩기로는 드로벤딩기, 3-롤벤딩기 및 스트레치벤딩기 등이 있다. 또한 벤딩에 사용하는 동력으로는 모터 또는 유압을 이용하는 것이 있으며, 이 동력의 수치제어를 적용한 CNC벤딩기 등이 개발 적용되고 있다.  Conventionally, bending machines for bending various pipes include a draw bending machine, a three-roll bending machine, a stretch bending machine, and the like. In addition, a motor or hydraulic pressure is used as the power for bending, and a CNC bending machine using numerical control of this power is being developed and applied.

하지만, 일반적으로 각종 배관용 및 건축물의 지지관용으로 사용되는 금속 파이프의 벤딩기로는 드로벤딩기가 가장 널리 사용되고 있으나, 이의 장치 중에서 CNC형 벤딩기는 고가이며, 일반형 벤딩기는 치수정밀도가 낮아 재현성이 부족한 실정이다. 또한 대부분 벤딩제품은 다품종 소량생산이 일반적이므로, 이를 동일한 벤딩기에서 제작하기 위해서는 원하는 곡률반경과 직경에 적합한 환형홈을 가진 구동롤러 및 슬라이딩형 클램프의 교환이 용이해야 하며, 특히 이의 클램프로 인한 파이프 외면에 긁힘 등의 문제가 발생하였다.  However, in general, a draw bending machine is most widely used as a bending machine for metal pipes used for various piping and building support pipes, but among these devices, a CNC type bending machine is expensive, and a general type bending machine has low dimensional accuracy and thus lacks reproducibility. to be. In addition, since most of the bending products are generally produced in small quantities in many kinds, in order to manufacture them in the same bending machine, it is necessary to easily replace the driving rollers and the sliding clamps having the annular grooves suitable for the desired curvature radius and diameter. Problems such as scratching occurred.
