摘　　要：介绍了一种液压控制系统及采集系统的实现方案。方案是在对型号为HHP28-120双动薄板拉深液压机的顶出缸油路进行改造的基础上,结合特殊的双层压边圈结构实现分段压边力的实时控制,并通过独立开发的控制及采集软件,方便地实现液压控制及数据采集。Realization of hydraulic control system and its sampling system have been introduced.Through rebuilding the oil path of the ejecting cylinder of Model HHP28 -120 sheet drawing hydraulic press,combined with a particular two-layer blank holder, control in real time of sectioned blank holder force has been realized. By a set of control and sampling software developed independently this system can easily accomplish the control and sampling task.
