手动弯管器见附图,通过更换模轮6、滚轮3,用两手的合力,可分别弯制φ6～φ16mm的管材。弯管时回转角0～120°。在设计弯管器时,可按常用管材的最大直径并根据滚轮3、模轮6的直径确定上、下轴4、7的距离。滚轮3尽量选较小的直径,模轮6应选较大的直径。为防止弯曲变形,可增大弯曲半径。施力手把为两件分离体,使用时,将左手把钩住被弯制的管件,再将右手把上的轴7与左手把相接,然后装上滚 Manual pipe bender see the photo, by changing the die wheel 6, roller 3, with both hands together, can be bent φ6 ~ φ16mm of the pipe. Elbow angle 0 ~ 120 °. When designing the pipe bender, the distance between the upper and lower shafts 4 and 7 can be determined according to the maximum diameter of common pipe and the diameter of the roller 3 and the die wheel 6. Roller 3 try to choose a smaller diameter, die wheel 6 should choose a larger diameter. To prevent bending deformation, bending radius can be increased. Shi force handle for the two separate body, the use of the left hand hook hook bent pipe, then the right hand shaft 7 and the left hand phase, then install the roll
