The invention belongs to the technical field of vehicles, and discloses a fender production method and a fender.The fender production method comprises the following steps that S100, the included angle and the curvature radius of the contour of a parting line, close to one side of an engine hood outer plate, of the fender and the curvature radius of a concave curved surface of a jaw area of the fender are set; s200, parameter optimization is conducted on a jaw transition area located between a mounting table and the jaw area, the curvature radius of the jaw transition area is larger than or equal to a first preset value, parameter optimization is conducted on the flanging height of a jaw, the flanging height of the jaw is made to be a second preset value, and the mounting table is located on the inner side of the fender; s300, drawing is conducted on the first web area to form an edge-shaped step; and S400, after the first web is flanged, a pressing plate is adopted for pressing the first web area. According to the method, the quality of the jaw area of the fender is controlled through the steps, the wave defects of the jaw area are reduced, and the production cost of the fender is reduced.
本发明属于车辆技术领域,公开了翼子板生产方法及翼子板,翼子板生产方法包括以下步骤:S100、设定翼子板靠近发动机罩外板一侧的分缝线轮廓的夹角和曲率半径以及翼子板的虎口区域的凹曲面的曲率半径;S200、对位于安装台与虎口区域之间的虎口过渡区进行参数优化,使虎口过渡区的曲率半径大于或等于第一预设值,对虎口的翻边高度进行参数优化,使虎口的翻边高度为第二预设值,其中,安装台位于翼子板的内侧;S300、对虎口区域进行拉延,以形成沿型台阶;S400、在虎口翻边之后,采用压料板对虎口区域进行压料。本发明采用以上步骤对翼子板的虎口区域进行质量控制,减少虎口区域的波浪缺陷,降低翼子板的生产成本。
