The deep drawing forming holds the important position in the processing, because of high production, simple operation, easy mechanization and automation. So, the research on metal sheet forming process of with coating is of important significance.
金属表面镀层处理是材料表面改性的重要方法,先对基材表面镀层处理后对带镀层材料精密成形是需要表面改性零部件的一种重要加工方式,拉深成形因具有生产效率高、操作简便、便于实现机械化和自动化等优点在加工中占有重要地位,因此对镀层金属薄板拉深成形进行研究具有重要意义。
