=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)。羅湖金屬精密拉伸五金件哪里好多次拉伸可以提高產(chǎn)品的合格率，不容易產(chǎn)生廢品，多次拉伸的中間去應(yīng)力，退火軟化。</p><div

拉伸件成型沖壓加工是禾聚精密的六大技術(shù)之一，技術(shù)特點(diǎn)：拉伸公差可達(dá)±0.015mm、外觀無瑕疵、可做到R/T＜1.0。拉伸件應(yīng)用于機(jī)械、電子、電器、儀表、汽車、航空、**產(chǎn)品。 </p> <p> <br /> </p> <p> 在拉伸件拉伸成型工藝中，有一次拉伸成型和多次拉伸成型。一次拉伸的特點(diǎn)是一次成型，可以提高生產(chǎn)效率，缺點(diǎn)是一次成型容易不到位，而且每次拉伸的變化程度是有要求的，不能變化太大。 </p> <p> <br /> </p> <p> 多次拉伸可以提高產(chǎn)品的合格率，不容易產(chǎn)生廢品，多次拉伸的中間去應(yīng)力，退火軟化。多次拉伸可以確保工件的精度，延伸系數(shù)以及生產(chǎn)效率都得到很大程度的提高。多次拉伸可以拉的更加勻稱，降低工件的不良率。 </p> <p> <br /> 具有很高的附著力和光潔度，是一種沖壓件防腐蝕涂層。羅湖金屬精密拉伸五金件哪里好</p><p

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(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 /> 廣州耐磨精密拉伸五金件工廠</p><p
