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(qiáng)度面板拉伸加工（Panel

style="text-indent:25px">拉伸系數(shù)非常重要，一個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)。但是，拉伸系數(shù)也不是固定不變的。影響拉伸系數(shù)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)行大概計算。拉伸件在調(diào)試模具過程中經(jīng)常會遇到拉裂、起皺等問題。如果出現(xiàn)拉裂，需要考慮材料流動問題，可以在凹模上涂潤滑油不要在凸模涂，或者在產(chǎn)品靠凹模一面覆0.013--0.018mm的薄膜就是鉗工師傅常用的纏繞膜。則皺，少則裂，按此方法判斷材料的流動情況。調(diào)整方案：調(diào)整壓邊圈的壓力、增加拉深筋、改變上下模鑲件的圓弧過度半徑、工件上切工藝口等。拉伸件總之是比較有技術(shù)含量的模具類型，不管是對設(shè)計、加工、組裝、還是調(diào)試都是一個挑戰(zhàn)，需要十分謹(jǐn)慎。</p><p style="text-indent:25px">深錐形件由于深度較大，坯料的變形程度較大，*靠坯料與凸模接觸的局部面積傳遞成形力，極易引起坯料局部過度變薄乃至破裂，需要經(jīng)過多次過渡逐漸成形。階梯拉伸法是首先將坯料拉伸成階梯形過渡件，其階梯外形與錐形部的內(nèi)形相切，***脹形成錐形。階梯過渡件的拉伸次數(shù)、工藝等與階梯圓筒件的拉伸相同多次拉伸成形的高矩形件，其變形不*與深圓筒形件的拉伸不同，與低盒形件的變形也有很大差別。圖1-46為多工位自動搬送壓力機(jī)進(jìn)行高矩形盒件加工時，多次拉伸過程中制件外形、尺寸伴隨拉伸高度的變化。原材料要冷卻到50°以下才能移到拉伸架上進(jìn)行拉伸加工。</p><div
