结合标定 4 0 0 0 0kN热模锻压力机公称力能特性的经验 ,介绍了锻压设备力能特性标定的重要性。着重介绍了大吨位热模锻压力机公称力能特性标定的特殊性和几个关键技术 ,它们包括防止离合器打滑、闷车、协调试样尺寸和数量等内容。从而作到既能标定出设备的公称力能 ,又能保证每次标定打击时 ,能量和载荷都不过载等 Combined with the experience of nominal force characteristics of 4000 hot stamping press, the importance of calibration of mechanical properties of forging equipment is introduced. The particularity and several key technologies of the nominal performance of the large tonnage hot die forging press are emphatically introduced. They include preventing the clutch from slipping, boring, coordinating the sample size and quantity. Thus, both the nominal force of the device can be calibrated, and the energy and the load can not be overloaded every time the calibration strike is performed
