產(chǎn)品的質(zhì)量和性能與其生產(chǎn)過程密不可分。為了保證產(chǎn)品質(zhì)量，有必要控制生產(chǎn)過程。以沖壓拉伸模為例。在生產(chǎn)中，其生產(chǎn)過程一般具有以下特點： </p> <p> <br /> </p> <p> 1.沖壓拉伸件模具可用于加工尺寸范圍大、形狀復(fù)雜的零件，如鐘表等小秒表、汽車縱梁、覆蓋件等。由于沖壓過程中材料的冷變形和硬化效應(yīng)，沖壓的強(qiáng)度和剛度較高。 </p> <p> <br /> </p> <p> 2.沖壓時，模具保證了沖壓件尺寸和形狀的準(zhǔn)確性，一般不會損壞沖壓件的表面質(zhì)量，模具使用壽命長。因此，沖壓質(zhì)量穩(wěn)定，互換性好，具有“一模一樣”的特點。 </p> <p> <br /> </p> <p> 3.沖壓一般不產(chǎn)生切屑，材料消耗少，不需要其他加熱設(shè)備，是一種節(jié)省材料和能源的加工方法，沖壓件成本較低。 </p> <p> <br /> </p> <p> 4.本發(fā)明生產(chǎn)效率高，操作方便，易于實現(xiàn)機(jī)械化和自動化。這是因為沖壓是通過沖壓模具和沖壓設(shè)備來完成的。普通壓力機(jī)的沖程數(shù)可達(dá)到每分鐘幾十次，高速壓力可達(dá)到每分鐘幾百次甚至幾千次，每個沖壓沖程可獲得一個沖頭。 </p> <p> <br />

=10°～30°的深錐形件，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。反向拉伸加工（Reverse drawing）：將前工序拉伸加工的工件，進(jìn)行反向拉伸，是再拉伸的一種。反向拉伸法可增加徑向拉應(yīng)力，對于防止起皺可收到較好效果。也有可能提高再拉伸的拉伸系數(shù)。</p><p> 五金沖壓件拉伸作為主要的沖壓工序之一，應(yīng)用非常***。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。 </p> <p> <br /> </p> <p> 帶凸緣半球形拉伸加工：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(yán)重變薄，或曲面部分的失穩(wěn)起皺。 </p> <p> 法蘭盤拉伸加工：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。
