【摘要】 自然增压充液拉深是一种综合了液体压边、摩擦保持、流体润滑、径向推力和预胀形优点的充液拉深方法。这里阐明了该方法对计算机智能化控制系统的要求,在YES-100试验机上建立了相应的计算机控制系统,通过对PCL-818数据采集卡的扩展实现了多种输入、输出量的采集与控制。使用Visual C++和ODBC编写了智能化充液拉深控制程序,主程序可以分为三个部分:工艺参数设定、实时过程控制和智能化模块,有效保证了筒形件充液拉深过程的有序进行和液体压力闭环控制。更多还原

【Abstract】 Passive pressurization hydraulic deep drawing is a new integrated method of hydromechanical deep drawing,which includes hydraulic blank holding,frictional preservation,fluid lubrication, radial pressure and prebulging. Considered the complexity of the deep drawing process,an intelligent computer control system has been built on the YES-100 material testing machine. Through extending the functions of a single PCL-818 data acquisition card the various digital and analog variables can be monitored and controlled. Moreover, the intelligent control program is programmed with Visual C++ and ODBC,which consists of parameter setting, real-time process control and intelligent module. The control program can successfully accomplish process control and fluid pressure closed-loop control of passive pressurization hydromechanical deep drawing.更多还原
