摘要
阐述了液压模锻锤的结构及工作原理。通过动量定理建立了全液压模锻锤液压缸的数学模型,为设定打击能量和打击次数的大小提供了依据,同时为实现模锻锤运行过程的精确控制提供了理论参考。并对锤头速度、位移、动能变化情况进行了试验仿真,通过仿真分析为其进一步实现模锻锤打击工序和打击能量的数控化和柔性化奠定了基础。
The structure and working principle of hydraulic die forging hammer have been introduced. The mathematics model for its hydraulic cylinder has been established on the basis of momentum theorem which is used to confirm the forging energy and blow number of times.Meanwhile, it offers theory reference for the precision control of the run process. The hammer's speed, displacement, and kinetic energy variety have been simulated. It provides foundation for realization of the further controllable and flexible of the forging energy and number.
