【摘要】：为了研究工艺参数对高强钢板杯形件单道次拉深旋压成形质量的影响规律,以旋压件的壁厚分布、直线度以及圆度均值作为评价指标,基于有限元分析软件ABAQUS对DP600高强钢板单道次拉深旋压成形过程进行数值模拟研究,并进行了试验验证。结果表明:在高强钢板杯形件单道次拉深旋压成形过程中,随着旋轮进给比f、旋轮圆角半径rρ以及旋轮与芯模间相对间隙值δ的增大,其壁厚分布的均匀性逐渐变好,直线度逐渐增加;圆度均值呈先减小后增加的趋势,并且均存在一最小值;当f=0.5 mm·r-1、rρ=10 mm及δ=-5%时,DP600高强钢板杯形件单道次拉深旋压成形时的质量最优。
[Abstract]:In order to study the influence of process parameters on the quality of single pass deep spinning of high strength steel sheet cup, the wall thickness distribution, straightness and roundness of spinning parts are taken as the evaluation indexes. Based on the finite element analysis software ABAQUS, the numerical simulation of single pass deep spinning process of DP600 high strength steel plate is carried out, and the experimental results are verified. The results show that the uniformity of wall thickness distribution becomes better with the increase of feed ratio f, radius r 蟻 and the relative gap value 未 between the rotary wheel and the core die in the process of single-pass deep spinning of the high-strength steel plate cup parts, and the results show that the uniformity of the wall thickness distribution becomes better with the increase of the feed ratio of the rotary wheel, the radius r 蟻 of the rotary wheel and the relative gap between the rotary wheel and the core die. The straightness increases gradually, the mean value of roundness decreases first and then increases, and there is a minimum value, and the quality is the best when f _ (0.5) mm r ~ (-1) r 蟻 _ (10 mm) and 未 ~ (-5) ~ (-5) are used in single-pass deep spinning forming of cup parts of high strength steel sheet.
