摘　　要：液压系统是薄板冲压液压机中重要的组成部分,主机动作、送料系统等基本动作都需要液压系统来完成,又由于其自身工作特性,是主要薄板冲压液压机的故障发生区。液压系统工作时,由于液压泵、液压阀、液压缸等元件的功率损失和管路的压力损失会转化成热能,使液压油温度上升。在对薄板冲压液压机中的液压系统热平衡进行分析基础上,开发了热平衡计算及优化软件,计算管路及阀的发热量,找到现有系统中发热关键因素,从而改善系统的发热量,对薄板冲压液压机系统设计有一定指导意义。Hydraulic system is the important composition of the large sheet stamping hydraulic press,which can help to achieve basic action of the large sheet stamping hydraulic press such as press moving,carriage system raising and so on.Hydraulic system is the main failure area owing to working characteristic of itself.Because the power loss of the components such as hydraulic pressure pumps,hydraulic valves,oil crocks and the pressure loss of the pipeline transform to heat,the temperature of the hydraulic oil rises up.the heat-balancing software system was developed based on analysis of the large sheet stamping hydraulic press hydraulic system,it can calculate the heat of pipe and valve,and find the key factor of system,improve the heat.The software can be good help to hydraulic system design.
