The invention relates to a wheel cover and a wheel cover manufacturing method. The wheel cover manufacturing method comprises the following steps that firstly, an independent plane part blank is used for forming a plane part of a wheel cover in a bending mode, and an independent protruding part blank is used for forming an arc-shaped protruding part of the wheel cover in a bending mode; and secondly, the plane part and the arc-shaped protruding part of the wheel cover are spliced and fixed to form the wheel cover. The wheel cover comprises a plane part and an arc-shaped protruding part, the arc-shaped protruding part is provided with an arc-shaped protrusion, and the plane part and the arc-shaped protruding part are mutually spliced and fixedly connected. The wheel cover blank is divided into two parts which are respectively placed on the stamping die to be stamped, so that the method has low pressure requirements on a press, the stamping step is easy to realize, and in the stamping step, only each part to be stamped needs to be loaded and unloaded, and compared with the whole wheel cover, each part to be stamped is light in weight, so that the stamping efficiency is greatly improved. And feeding and discharging are convenient, and the mold cost input is small.

    本发明涉及一种轮罩及轮罩制造方法。轮罩制造方法,该方法包括以下步骤:第一步,利用单独的平面部分坯料折弯成型轮罩的平面部分,利用单独的凸起部分坯料折弯成型轮罩的弧形凸起部分;第二步,将轮罩的平面部分和弧形凸起部分拼接并固定,以形成轮罩。轮罩包括平面部分和弧形凸起部分,所述弧形凸起部分上具有弧形凸起,所述平面部分与弧形凸起部分相互拼接并固定连接。将轮罩坯料分为两部分,分别放置在冲压模具上进行冲压,这种方式对压机的压力要求较低,冲压步骤容易实现,并且在冲压步骤中,仅需要对各个待冲压部分进行上料和卸料,相对于整体轮罩,各个待冲压部分的重量较轻,上料和卸料均较为方便,模具成本投入较小。
