普通四辊卷板机主传动为机械传动,零件多,使制造和安装误差增加;传动部分和工作机座为两个独立体,工作时机器运动不平稳、噪音大,影响机器的精度和使用寿命;侧辊、下辊的升降运动为液压油缸驱动,且采用普通开关阀控制,卷制精度都不高,整个机器的传动效率较低,且占地面积大,结构不紧凑,外形不美观。加之用户要求对板料进行多弧卷取,因此,需对四辊卷机的传动部分进行改进。上辊采用马达直接驱动后,使四辊卷板机成为结构合
Ordinary four-roll plate bending machine main drive mechanical transmission, parts and more manufacturing and installation errors increase; transmission part and the working base for the two separate bodies, work machine movement is not stable, noise, affecting the accuracy and use of the machine Life; the side roller, the lower roller lifting hydraulic cylinder drive, and the use of ordinary switching valve control, rolling precision are not high, the entire machine transmission efficiency is low, and the large area, the structure is not compact, the appearance is not good . Coupled with the user requirements for multi-arc sheet coiling, therefore, need to be four-roll drive part of the improvement. The upper roller is driven directly by the motor to make the four-roller bending machine into a structure
