1材料冲压过程常见缺陷冲压成形过程主要是利用磨具对金属板料进行弯曲、拉深、胀形、拉延和翻边等加工,最终得到所需要的零件。因板材成形过程的复杂性,冲压原材料、加工过程、模具状态、公辅介质等都会影响冲压质量。因此,冲压成形过程中常常由同一原因产生不同缺陷,或不同原因产生同一缺陷,正确识别这些缺陷对快速整改、提高生产效率和降低损失等非常重要。
1 common defects in stamping process The stamping process is mainly the use of abrasive metal sheet bending, drawing, bulging, drawing and flange processing, and ultimately get the required parts. Due to the complexity of sheet metal forming process, stamping of raw materials, processing, mold status, the public and other media will affect the quality of stamping. Therefore, the stamping process often produce the same reason for different defects, or different causes of the same defects, the correct identification of these defects for rapid rectification and improve productivity and reduce losses is very important.
