style="text-indent:25px">球形件拉伸時(shí)，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(yán)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(jìn)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，對前工序拉伸產(chǎn)品的凸緣部進(jìn)行角形再拉伸加工，此種加工要求材料具有良好的塑性，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(jìn)行再拉伸加工，福田本地精密拉伸五金件加工廠。寬凸緣拉伸件，***次拉伸時(shí)就拉伸成所要求的凸緣直徑，福田本地精密拉伸五金件加工廠，福田本地精密拉伸五金件加工廠，在其后再拉伸時(shí)，凸緣直徑保持不變。這取決于塑性材料的拉伸變形量。福田本地精密拉伸五金件加工廠</p><div

style="text-indent:25px">不銹鋼拉伸中導(dǎo)致開裂形成的原因有：奧氏體不銹鋼的冷作硬化較高；奧氏體不銹鋼為亞穩(wěn)定型，在變形時(shí)會出現(xiàn)變相，誘發(fā)馬氏體相；馬氏體相又脆，因此會容易出現(xiàn)開裂。在塑性變形中，隨著變形量的增加，誘發(fā)馬氏體含量也會隨著變形量的增加而增高，殘余應(yīng)力則越大，殘余應(yīng)力和馬氏體含量的關(guān)系：誘發(fā)馬氏體相含量增高，引發(fā)殘余的應(yīng)力越大，在沖壓過程中便容易開裂。與普通拉伸不同，變薄拉伸主要是在拉伸過程中改變拉伸件筒壁的厚度。凸凹模之間的間隙小于毛坯厚度，毛坯直壁部分在通過間隙時(shí)，處于較大的均勻壓應(yīng)力之下，拉伸過程中壁厚變薄的同時(shí)，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強(qiáng)度面板產(chǎn)品是板材沖壓件，表面形狀復(fù)雜。在拉伸工序中，毛坯變形復(fù)雜，其成形性質(zhì)已非簡單的拉伸成形，而是拉深與脹形同時(shí)存在的復(fù)合成形五金沖壓拉伸成型作為主要的沖壓工序之一，應(yīng)用非常多。用拉伸工藝可以制成各種圓筒形、矩形、階梯形、球形、錐形、拋物線形及其他不規(guī)則形狀的薄壁零件。寶安精密拉伸五金件沖壓拉伸加工中為什么要用塑性好的金屬材料？</p><div

拉伸系數(shù)非常重要，一個(gè)拉伸件需要分幾步拉伸才能保證不出現(xiàn)開裂、起皺等問題都需要用拉伸系數(shù)公式進(jìn)行計(jì)算。是拉伸工藝核算中的首要工藝參數(shù)之一，一般用它來決議拉伸的次序和次數(shù)。 </p> <p> <br /> </p> <p> 但是，拉伸系數(shù)也不是固定不變的。影響拉伸系數(shù)m的因素比較多，其中包括：材料型號、厚度、拉伸結(jié)構(gòu)類型、拉伸次數(shù)、拉伸速度、拉伸鑲件圓弧過度大小等等。不過，一般都可以查表進(jìn)行大概計(jì)算。 </p> <p> <br /> </p><p style="text-indent:25px">山形拉伸加工（Hill

drawing）：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(shí)存在的復(fù)合成形。壓料面上坯件的變形為拉伸變形（徑向?yàn)槔瓚?yīng)力，切向?yàn)閴簯?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）。馬氏體相又脆，因此會容易出現(xiàn)開裂。</p><div
