1.2 沖壓材料的選用
    沖壓零件所用的材料,不僅要適合零件在機器中
的工作條件,而且要適合沖壓過程中材料變形特點及
變形程度所決定的制造工藝要求,即應具有足夠的強
度及較高的可塑性。
      (1)選用原則
    1)對于拉深及復雜彎曲件,應選用成形性好的
材料。
    2)對于彎曲件,應考慮材料的纖維方向。
    3)在保證產品質量的前提下,盡量降低所使用
的材料的價格。用薄料代替厚料;用鋼鐵材料代替非
鐵材料;充分利用邊角余料,以降低成本。
    4)考慮后繼工序的要求,如沖壓后需焊接、涂
漆、鍍膜處理的零件,應選用酸洗鋼板.
    (2)沖壓用的材料(見表4.4-3,表4.4-4)
沖壓件對材料的要求適用于精沖的材料
