基于PLC与凸轮组合控制的伺服压力机设计

摘要

针对钣金件、模具等冲压任务,高效率的压力机对于缩短加工周期起到决定性的作用.详细介绍了一种新型的压力机结构,在集伺服、液压驱动、多级传动链引导的基础上,通过凸轮机构来统一完成各冲压位置信息的反馈,从而达到与PLC系统的高度融合,改变了单一化控制系统中传感器的外接分布以及速度的不可控性,增强了压力机系统的灵活度和稳定性.%Hign efficient press plays an important role in shortening the processing cycle in pressing metal plate and mold.The paper introduces the structure of the new type press,including its servo hydraulic drive and multistage transmission chain guide and uses the cam mechanism to uniformly finish the feedback of the punching position information, so as to achieve the high integration with the PLC system, thus changing the single control system sensor external distribution and velocity variability, and enhancing the press system flexibility and stability.
