在使用冲压机的连续自动作业工序中,必须将钢板等材料在与机器动作同步的情况下以一定的尺寸进给。这里介绍一个应用电气式无级变速机(由步进电机和驱动装置组成)实现上述进给的实例。 其中,电气变速机驱动用的电动机是使用步进电机,这在定尺进给的材料比较轻时非常有效,并很容易组成系统。 因步进电机是与驱动装置组合在一起的,它通过输入脉冲频率确定旋转速度,再通过给定的脉冲数确定旋
In the continuous automatic working process using a press machine, the material such as the steel plate must be fed to a certain size in synchronization with the operation of the machine. Here is an example of using an electric CVT (consisting of a stepper motor and a drive) to realize the above feed. Among them, the electrical transmission drive motor is the use of stepper motor, which in the length of the feed material is very light and very effective and easy to form a system. Because the stepper motor is combined with the drive unit, it determines the rotation speed by inputting the pulse frequency and then determines the rotation by the given pulse number
