The invention discloses an automobile side wall outer plate forming process method and an automobile side wall outer plate. The automobile side body outer plate forming process method comprises the following steps that after a waste area of a blank is punctured for the first time, the blank is preliminarily drawn in the first half stroke of a stamping die; after secondary puncturing is carried out on the waste material area, drawing of the blank is completed in the second half stroke of the stamping die; cutting off waste in a waste area of the blank to form a semi-finished product of the side wall outer plate; and flanging and shaping the side body outer plate semi-finished product to form a side body outer plate finished product. Corresponding waste areas which are prone to cracking are punctured twice in the drawing and stamping process, qualified stamping products can be machined on the premise that cracking is reduced through one stamping die, only two stamping dies need to be arranged in the whole technological process for producing side body outer plate finished products, and the production efficiency is improved. The problems that an existing automobile side wall outer plate forming process method is long in manufacturing period, multiple in mold and high in cost are solved.

    本发明公开一种汽车侧围外板成形工艺方法和汽车侧围外板。汽车侧围外板成形工艺方法,包括如下步骤:在坯料的废料区域进行一次刺破后,在冲压模具的前半段冲程对坯料进行初步拉延;在废料区域进行二次刺破后,在冲压模具的后半段冲程对坯料完成拉延;切除坯料的废料区域的废料,以形成侧围外板半成品;对侧围外板半成品进行翻边和整形,以形成侧围外板成品。通过在拉延冲压工序分两次对容易开裂的对应的废料区域进行刺破,并通过一套冲压模具能够在减少开裂的前提下加工出合格的冲压产品,整个生产侧围外板成品的工艺流程中,只需设置两套冲压模具即可,以解决现有的汽车侧围外板成形工艺方法制造周期长,模具多,成本高的问题。
