style="text-indent:25px">變薄拉伸加工（Ironing）：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，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，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強度面板拉伸加工（Panel

style="text-indent:25px">碳鋼板在選用拉伸油時首先應(yīng)該注意的是拉伸油的粘度。根據(jù)工藝難易度和脫脂條件來決定較佳粘度因為和氯系添加劑會發(fā)生化學(xué)反應(yīng)，所以鍍鋅鋼板在選用拉伸油時應(yīng)注意氯型沖壓油可能發(fā)生白銹的問題，而使用億達渤潤硫型拉伸油可以避免生銹問題不銹鋼是容易產(chǎn)生硬化的材料，要求使用油膜強度高、抗燒結(jié)性好的拉伸油。一般使用含有硫氯復(fù)合型添加劑的拉伸油，在保證極壓性能的同時避免工件出現(xiàn)毛刺、破裂等問題自主研發(fā)的拉伸油系列產(chǎn)品具有優(yōu)異的極壓抗磨性能，能有效的保護沖模、大幅度提高生產(chǎn)效率、延長設(shè)備的使用壽命</p><p> 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**高；奧氏體不銹鋼為亞穩(wěn)定型，在變形時會出現(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。 </p> <p> </p> <p> 造成表面劃痕的因素有：不銹鋼拉伸件的表面會出現(xiàn)劃痕是由于工件與模具表面存在相對的移動，在一定的壓力促使下，導(dǎo)致坯料和模具局部表面直接產(chǎn)生摩擦，加之坯料的變形熱使得坯料和金屑熔蓋在模具的表面上，使工件外表擦傷產(chǎn)生劃痕。 </p> <p> <br />
