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進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。技術特點：拉伸公差可達±0.015mm、外觀無瑕疵、可做到R/T＜1.0。</p><div

drawing）：沖壓件的側壁為斜面時，側壁在沖壓過程中是懸空的，不貼模，直到成形結束時才貼模。成形時側壁的不同部位變形特點不完全相同。丘形拉伸加工（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（徑向為拉應力，切向為壓應力），而輪廓內部（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力）。溫度過高會燙到作業(yè)員和燙壞坯毛條，也不能徹底的消除材料內應力從而產(chǎn)生廢品。廣州金屬精密拉伸五金件</p><p
