| 摘 要： | 通过分析连杆及其辊锻件,并综合考虑锻件节料最大化及工艺的可行性,对连杆辊锻件各区段长度及杆部横截面积进行了重新分配.根据新辊锻件最小截而的总延伸系数,试选3套不同的槽系方案分别计算分析,最终确定"椭圆-方形-椭圆-方形"槽系组合为该连杆制坯辊锻的优化方案,并设计了相应的辊锻模.经三维有限元数值仿真及实物生产证实:辊锻结果与设计吻合良好,单件连杆锻件下料重量降低了17%.

| Abstract: | Length of each segment on the roll forging piece and cross section area of its rod were redistributed by analyzing the connecting rod and its roll forging piece.Meanwhile,the maximum of material economy and feasibility of process were taken into account synthetically.According to total elongation coefficient of minimum cross section of the new roll forging piece,three different groove systems were chosen to carry out the calculation and analysis respectively.Finally,ellipse-square-ellipse-squaregroove syste... |
