The invention discloses a method for preventing a vehicle body lower protection plate from generating a wavy edge, which comprises the following steps: S1, a formed vehicle body lower protection plate is provided with buckle fixing seats matched with buckles, and the buckle fixing seats are arranged along a flanging on one side of the vehicle body lower protection plate; s2, an auxiliary structure for avoiding the wavy edge is arranged between the turned edge of the vehicle body lower protection plate and the buckle fixing base, and the auxiliary structure for avoiding the wavy edge can make the supporting force of all parts of the turned edge consistent; and S3, the turned-over edge on the vehicle body lower protection plate is detected, the vehicle body lower protection plate is sprayed after being qualified, and the vehicle body lower protection plate is assembled after being detected to be qualified. By the adoption of the method, the problem that the turned-over edge of the vehicle body lower protection plate is prone to generating the wavy edge in the injection molding process can be effectively solved, the turned-over edge of the vehicle body lower protection plate does not generate the wavy edge after spraying, the subsequent shape correcting procedure is not needed any more, the labor cost and the manufacturing cost are reduced, the manufacturing period is shortened, and the production efficiency is improved. And meanwhile, the problem of unstable quality does not exist, and the forming quality of the vehicle body lower protection plate is ensured.

    本发明公开了一种避免车身下护板出现波浪边的方法,包括:S1、成型的车身下护板上具有配合卡扣的卡扣固定座,该卡扣固定座沿车身下护板一侧的翻边进行排布;S2、将车身下护板的翻边与卡扣固定座之间设置有规避波浪边的辅助结构,该规避波浪边的辅助结构能够使其翻边各部分的支撑力达到一致;S3、对车身下护板上的翻边进行检测,合格后对车身下护板进行喷涂,检测合格后装配。采用以上方法,不仅能够有效避免车身下护板的翻边在注塑成型时易产生波浪边的问题,而且在喷涂后车身下护板的翻边同样不会出现波浪边,并且不再需要后续的校形工序,既降低了人工及制造成本,又缩短了制造周期,同时不存在质量不稳定的问题,确保了车身下护板的成型质量。
