复合伺服驱动压边力控制方法及执行机构设计

摘要

Based on servo motor control and variable transmission ratio of a six--bar mechanism, a composite technique for BHF controlled by servo motor and multi--bar linkages was proposed. The principles of the BHF control were analyzed and the BHF actuator was designed according to some technology requirements such as slow loading and fast return during the deep drawing process. Only a small electrical power can meet a higher BHF by integrated servo motor with six--bar linkages.%基于伺服电机的可控性和六杆机构的变传动比及增力特性,提出了一种复合伺服驱动压边力控制方法。在分析数控伺服驱动压边力控制原理的基础上,根据慢速加载、快速返程的工艺要求,设计了压边力执行机构,并对其进行了系统仿真。采用复合伺服驱动压边力控制方法,使压边装置在产生较大压边力的情况下,仅需较小的电机功率,就可以满足压边过程中的压边力和行程的工艺要求。
