摘　　要：论述了某产品零件顶板成形的模具设计、制造和零件成形工艺过程。针对零件属于厚板、角部圆角半径较大的矩形盒形件拉深冲压成形特点,采用"最小极限毛坯"和热拉深成形方法,在无刚弹性压边的情况下,零件采用一副模具一次冲压成形。结果表明,提高了生产效率,降低了成本,且生产出合格零件。Die design, manufacturing and part forming process for the roof part of the prod- uct were introduced. Considering the forming characteristic that the part is using thick plate to make a rectangular box with deep drawing, ＂minimum limit of blank＂ and thermal deep- drawing method were used. Without rigid-elastic blank pressing, the part was single step formed with one set of die. The result shows that acceptable product can be produced with improved production efficiency and reduced cost.
