The invention relates to the technical field of vehicle parts, in particular to a rear fender forming method, a drawing die, a rear fender and a vehicle. The rear fender forming method comprises the following steps of blanking a slab; drawing the slab after blanking to form a plate having a rear fender profile, wherein the plate having the rear fender profile is provided with a first part forminga lower flange of the rear fender and a second part extending outwards from the first part in a coplanar mode in order to form a second part of a free end; and finally forming the plate having the rear fender profile, and forming the rear fender, wherein the second part is sheared, so that the first part forms the lower flange of the rear fender. According to the forming method, the scrap rate canbe reduced, and the material utilization of the slab can be increased, so that the cost can be reduced.
本发明涉及车辆零部件技术领域,特别涉及一种后翼子板成型方法、拉延模具、后翼子板及车辆。该后翼子板成型方法包括:将板坯落料;将落料后的板坯拉延,形成具有后翼子板轮廓的板材,其中具有后翼子板轮廓的板材具有形成后翼子板的下部法兰的第一部分以及共平面地从第一部分继续向外延伸以形成自由端的第二部分;并且将具有后翼子板轮廓的板材最终成型,形成后翼子板,其中第二部分被剪掉使得第一部分形成所述后翼子板的下部法兰。该成型方法能够减少废料率、增加板坯的材料利用率从而降低成本。
