摘要
对热压包边成型两工位的机械结构、设计原理及生产工艺进行了简单的介绍,以Siemens PLC和HMI作为人机界面,采用Siemens S120变频器做驱动控制。利用红外辐射加热灯管对产品进行加热。由于在生产工艺过程中,往往压力超调导致工件报废,所以,也提出滑模控制原理对同步电机进行控制,并且与传统的PID控制理论进行比对后,发现滑模变结构控制在鲁棒性方面的优势明显。
This paper introduced the mechanical structure and designing principal, the production process of the compression forming machine. It was with Siemens PLC and HMI as the man-machine interface, SEW inverter as the main control unit of constant torque. It realized closed-loop control of temperature of module constant temperature treatment. In the production process, because work pieces were scrapped occasionally caused by pressure overshoot, this paper also presented mcthod to accurately control the pressure, to reduce the pressure overshoot measures, and to overcome the bottleneck encountered in the actual production process.
