基于高速精密冲床的热态特性,对高速精密冲床进行了热源分析与传热机制分析,计算了冲床的热分析的初始条件及边界条件,利用Solid Works软件建立冲床整机的有限元模型,运用ANSYS软件对冲床进行热─结构耦合分析,求解出该高速冲床处于稳态环境下的整机的温度场和变形场,分析出冲床的加工误差。对比红外热像仪测得的实际冲床温度值,验证了温度场仿真分析结果的可靠性,为冲床的结构优化设计和热平衡设计提供理论依据。
Based on the thermal characteristics of high speed precision press, the heat source analysis and heat transfer mechanism of the high speed precision press were analyzed. The initial conditions and boundary conditions of thermal analysis of press were calculated. The finite element model of punch press was established by Solid Works software. ANSYS software for heat-structure coupling analysis of the punch, the solution to the high-speed punch in steady-state environment of the machine temperature and deformation field, analysis of the punch machining error. Comparing the real punch temperature measured by the infrared camera, the reliability of the simulation results of the temperature field is verified, which provides a theoretical basis for the structural optimization design and thermal balance design of the punch press.
