摘　　要：拧丝机构是液压打捆机的核心部件,它以液压油为动力,PLC控制实现拧丝头的动作。原地旋转的拧丝机构在使用过程中,经常出现拧断盘条的现象。为克服此缺陷,设计出了边旋转边前进的拧丝机构,这样打出的瓣结要比原地旋转打出的瓣结牢固可靠,强度高,不易散捆。需计算出完成两个动作的理论数据,一个是通过拧丝缸旋转的圈数和前进的距离求出螺旋传动的各个参数。另一个是通过盘条的强度以及拧丝缸芯轴动作时产生的摩擦力,来求出所需的扭矩,进而计算出所马达选型的基本参数,确定马达的型号。Twisting machine is the center of the hydraulic binding machine,powered by hydraulic oil,and controlled and fulfilled the action of twist head by PLC.In the course,twisting machine can twist off the steel wire rods easily.In order to overcome this shortcoming,it designs the twist machine spinning as moving forward.The knot is more solid and reliable,and not easy to loose.The theory data of two actions is needed： one is each parameter of power screw calculated by the number of twisting cylinder spinning and the distance moving forward;another is torque by the strength of steel wire rods and friction force dabber of twist cylinder working,so as to calculate the basic parameter of motor to make sure the model of the motor.
