基于ANSYS的板料成型系统模内加热模块热分析

针对目前板料热成形过程中存在的能量浪费、板料氧化严重等缺点，文章对模内加热方案进行研究探讨，使用ANSYS-Icepack对板料冲压成形的模内加热温度场进行模拟分析，并以此基础做出实物并调试对比模拟状况。结果显示：对于该模架，上下模1 000 W的热源同时加热时，加热组块最高温度可达近400℃，中间板材可加热到300 qC以上，10min之后散热和加热接近平衡。按该模型设计的实际加热系统的温度分布与模拟基本接近。该研究对模内加热模块的设计进行了模拟与初步的试验，将有助于板料热成形技术方面发展。

Analysis of Simulation for Heating Module in Mould Based on ANSYS

For energy waste and serious oxidation of sheet metal existing during the current sheet thermoforming process,the research of mold heating program was discuss. ANSYS-Icepack was used to analysis the mould heating for sheetmetal forming. Simulation results show that while heating the upper and lower mold by using heat source of I 000 Wsimultaneously, the maximum temperature on the mould can reach about 400 0C. The sheet can be heated to above300 0C . and the process of cooling and heating reaches equilibrium about ten minutes later. Temperature distribution of the actual heating system designed according to the model is close to the simulation results. The design of heating module in mould is simulated and experimented preliminary, which will help the development of the sheet hot forming technology.
