针对一些航空航天三通管件毛坯料厚度薄,成形后厚度要求严格,结构复杂等难于成形特点,对三通半管拉深成形过程的进行了研究。运用PAMSTAMP模拟软件研究不同参数下半管成形后的厚度和质量,分析了凹模圆角半径、凸凹模间隙、压边力对零件成形质量的影响,并获得了最优的工艺参数。用于指导生产,降低了生产周期和成本。 Aiming at the thinness of some blank of the aerospace tee pipe fittings, the requirement of thick thickness after forming, the complex structure and so on, the forming process of the three-way half pipe is studied. The thickness and quality of the semi-tube after forming under different parameters were studied by using PAMSTAMP simulation software. The influence of the fillet radius, punch-die clearance and blank holder force on the forming quality of the part was analyzed and the optimum process parameters were obtained. Used to guide the production, reducing the production cycle and cost.
