摘要
在等速万向节滑套温反挤成形工序中,凸模工作带不仅承受高载荷,还承受冷热循环和强摩擦作用,极易磨损。为了设计结构合理的凸模,建立了等速万向节滑套温反挤凸模的模拟模型,利用数值模拟技术分析了不同凸模圆角半径和凸模端面锥角对凸模载荷和温度分布的影响。通过分析得出凸模圆角半径R=5 mm、凸模端面锥角θ=10°时的凸模结构较为合理,为温反挤凸模结构设计提供一定的参考。
In the warm backward extrusion process of CVJ spherical housing, the punch was subjected to not only the high loading, but also the thermocycling and strong friction, which caused the punch worn easily. In order to design reasonable punch structure, the simulation model of warm backward extrusion was established, and the influence of the punch radius and angle on the punch load and temperature distribution were analyzed by using numerical simulation technology. Finally the reasonable punch structure of the punch radius R=5 mm and punch angle θ=10° was obtained based on the simulation analysis, which provided references for the structure design of warm backward extrusion punch.
