摘要
针对热锻模损伤主要发生在模具表面的情况,构想使用梯度功能材料对均质材料制造的热锻模进行表面处理,阐述了梯度材料锻模表面涂层的设计方法,建立了基于Deform软件的热锻成形有限元模型,分析对比了均质热锻模与梯度材料表面涂层热锻模在锻造生产后的温度场和应力场,从而论证了在热锻模表面进行梯度材料表面复合涂层处理的优越性。
Because hot forging die damage mainly occurres on the surface of the die, the functionally gradient materials （FGM） will be used on the surface of hot forging die with homogeneous materials. In this paper design methods of hot forging die based on the gradient material surface coating were described and finite element model of hot forging process was built. Then analysis and comparison of temperature field and thermal stress field in the homogeneous forging die and FGM coating surface forging die were obtained and the advantage of the FGM coating die was demonstrated. The above research can provide a design and manufacture basis for FGM forging dies.
