摘　　要：通过对某车型汽车前地板制件的冲压成形工艺进行分析,并对该双动拉伸模的设计过程作了一定的阐述。在模具设计过程中,为了避免制件在拉伸工序因深度过大造成的制件中部无法正常拉伸成形,拉伸模压料圈在中部位置设计了预成形部件,实现了板料在拉伸过程中在中部的预成形,后端中段水平压料面处增加了搓板式纵向吸料筋,顺利实现拉伸成形。拉伸模状态稳定,制件尺寸合格,外观良好,达到了设计要求,经过了批量生产的考验,工艺目标达成。This article analyzes the stamping forming process of the front floor part of a certain vehicle model,and elaborates on the design process of the double action drawing die.In the process of die design,in order to avoid the inability of the middle part of the workpiece to be properly drawn and formed due to excessive depth during the drawing process,a pre-forming component is designed for the pressing ring of the drawing die in the middle position.The pre-forming of the sheet metal in the middle during the deep drawing process has been achieved,and a washboard type longitudinal suction drawbead has been added at the horizontal pressing surface of the middle section of the rear end,successfully achieving deep drawing forming.The state of the drawing die is stable,the dimensions of the parts are qualified,the appearance is good,and the design requirements have been met.After the test of mass production,the process objectives have been achieved.
