drawing）：超過拉伸加工極限的拉伸加工產(chǎn)品，需要經(jīng)過兩次以上的多次拉伸方能完成。經(jīng)過前工位深度方向拉伸加工的產(chǎn)品，在深度方向進行再拉伸加工。寬凸緣拉伸件，***次拉伸時就拉伸成所要求的凸緣直徑，在其后再拉伸時，凸緣直徑保持不變。曲面成形加工（Surface

style="text-indent:25px">丘形蓋板件在成形過程中的坯件變形不是簡單的拉伸變形，而是拉伸和脹形變形同時存在的復合成形。壓料面上坯件的變形為拉伸變形（徑向為拉應(yīng)力，切向為壓應(yīng)力），而輪廓內(nèi)部（特別是中心區(qū)域）坯件的變形為脹形變形（徑向和切向均為拉應(yīng)力）球形件拉伸時，毛坯與凸模的球形頂部局部接觸，其余大部分處于懸空的不受約束的自由狀態(tài)。因此，此類球面零件拉伸的主要工藝問題在于局部接觸部分的嚴重變薄，或曲面部分的失穩(wěn)起皺將拉伸產(chǎn)品的法蘭盤部分進行淺拉伸的加工。其應(yīng)力應(yīng)變情況類似于壓縮翻邊。由于切向受壓應(yīng)力，容易起皺，故成形極限主要受壓縮起皺的限制。這兩種特殊水泥涂層均適用于沖壓拉伸件的內(nèi)防腐，提高抵抗侵蝕的能力。</p><div
