摘要
通过对国产08Al钢板四种试样的成型试验,研究了成型时板料向凹模的流入量与技术参数之间的关系。其中板料的直力应变状态、轧制方向、厚度和坯料尺寸等因素都影响成型时板料内的流入量。增大压边力,将减少板料向凹模内的流入量。
Based on a formation experiment of four samples of domestic 08Al sheet steel, the relations between the sheet steel amount drawn into die cavity during formation and technological parameter have been investigated. Among them several factors, such as the stress and strain conditions of sheet steel, rotling dcrection, thickress and sizes of blanks, will influence the sheet amount drawn into die cavity. Increasing the force applied on sheet edge will reduce the sheet amount drawn into die cavity.
