【摘要】 精密剪切是重要的下料方法。根据精密剪切的原理,设计了精密剪切设备,在建立零部件模型的基础上,运用三维CAD工程应用软件Pro/Engineer对其进行了虚拟装配。通过自下而上、自顶向下的虚拟装配方法,实现了精密剪切部件的虚拟装配,为该设备的仿真和开发奠定了基础。更多还原

【Abstract】 Accurate shear is an important unloading method . According to the principle of accurate shear, have designed the accurate shear equipmento on the basis of establishing spare part model, Use three - dimensional CAD project application software Pro/ Engineer to assemble it virtually. Through from bottom to top, top - down virtual assembly method, have realized the virtual assembly of the accurate shear part, Have established the foundation for the emulation and development of this equipment.更多还原
