以运输机刮板锻造工艺为研究对象,通过数值模拟研究了变形、热传导、变形生热、摩擦生热和磨损等因素对体积成形的影响,建立了成形过程中多因素动态耦合仿真模型。应用Archard模型分析了模具在复杂多因素耦合情况下的磨损,预测了单次磨损的深度分布,为间接预测模具寿命提供了依据。分析了锻造成形后的模具及锻件温度场分布、成形载荷等,为评价刮板热塑性成形工艺提供了理论依据。
Taking the scraper forging technology of transporter as the research object, the influence of deformation, heat conduction, deformation heat generation, frictional heat generation and wear on the volume forming was studied by numerical simulation. A multi-factor dynamic coupled simulation model was established. The Archard model was applied to analyze the wear of the die under complicated multi-factor coupling conditions. The depth distribution of the single wear was predicted, which provided the basis for indirectly predicting the die life. The temperature field distribution and forming load of the die and forging after forging are analyzed, which provides a theoretical basis for the evaluation of the thermoplastic forming process of the squeegee.
