摘要
为探究旋压成形过程中结构参数及工艺参数对柱塞泵柱塞滑靴球铰组合性能的影响规律,以滑靴裙部壁厚、座圈高度、主轴转速、旋轮进给比为试验因素,以拉脱力、旋压力、最大摆角为优化目标设计正交试验,利用极差法与灰色关联度分析法对正交试验数据进行分析,得到了结构参数及工艺参数对不同优化目标的影响规律,并对两组优化后的参数组合进行了进一步对比分析。结果表明:各参数影响程度由大到小依次为:座圈高度>滑靴裙部壁厚>旋轮进给比>主轴转速,通过灰色关联度优化后的最优参数组合为:座圈高度为2.5mm、滑靴裙部壁厚为1mm、旋轮进给比为0.24mm·r^(-1)、主轴转速为420r·min^(-1)。
In order to explore the influence laws of structural parameters and process parameters during the spinning process on the com-bined performance of plunger-slipper ball joint for plunger pump,taking the wall thickness of slipper skirt,height of seat ring,spindle speed and feeding ratio of rotary wheel as the test factors,and the pull-off force,spinning force and maximum swing angle as the optimiza-tion objectives,the orthogonal test was designed,and the orthogonal test data were analyzed by the range method and the grey correlation degree analysis method.Then,the influence laws of structural parameters and process parameters on the different optimization targets were obtained,and the two groups of optimized parameter combinations were further compared and analyzed.The results show that the influence order of each parameter from large to small is height of seat ring>wall thickness of slipper skirt>feeding rate of rotary wheel>spindle speed.Thus,the optimal parameter combination after grey correlation optimization is the height of seat ring of 2.5 mm,the wall thickness of slipper skirt of 1 mm,the feeding ratio of rotary wheel of 0.24 mm·r^(-1) and the spindle speed of 420 r·min^(-1).
