The invention provides a fender machining method, a fender assembly and an automobile. The fender machining method comprises the steps that one-time stamping is conducted on a fender, a main body part and a corner part of a bright strip groove are obtained, the corner part is the area, close to two adjacent groove walls, in the bright strip groove, the length of the corner part accounts for 20-30% of the length of the whole bright strip groove, and the distance from the corner part to a notch of the bright strip groove is smaller than that from the main body part to the notch of the bright strip groove; a process hole is processed in the corner part; and the corner part is subjected to secondary stamping, so that the distance from the corner part to the notch of the bright strip groove is equal to the distance from the main body part to the notch of the bright strip groove. According to the fender machining method, corrugated defects are not prone to being generated on a fender on the periphery of the corner part of the bright strip groove, the smoothness of the surface of the fender can be kept, and the overall appearance of the fender is improved.

    本申请提供一种翼子板加工方法、翼子板组件及汽车,翼子板加工方法包括在翼子板上一次冲压,得到亮条槽的主体部以及拐角部,其中,拐角部为亮条槽中靠近相邻的两个槽壁的区域,拐角部的长度占整个亮条槽长度的20‑30%,拐角部到亮条槽的槽口的距离小于主体部到亮条槽的槽口的距离;在拐角部上加工出工艺孔;二次冲压拐角部,使拐角部到亮条槽的槽口的距离等于主体部到亮条槽的槽口的距离。本申请通过的翼子板加工方法不易在亮条槽拐角部周边的翼子板上产生波纹状缺陷,有利于保持翼子板表面的平整性,提升翼子板的整体外观。
