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、拉伸結構類型、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含量的模具類型，不管是對設計、加工、組裝、還是調(diào)試都是一個挑戰(zhàn)，需要十分謹慎。耐磨精密拉伸五金件廠家可采用熱處理來獲取良好的機械性能、物理性能和抗腐蝕性能。</p><div

style="text-indent:25px">法蘭盤拉伸加工：將拉伸產(chǎn)品的法蘭盤部分進行淺拉伸的加工。其應力應變情況類似于壓縮翻邊。由于切向受壓應力，容易起皺，故成形極限主要受壓縮起皺的限制。邊緣拉伸加工：對前工序拉伸產(chǎn)品的凸緣部進行角形再拉伸加工，此種加工要求材料具有良好的塑性。深度拉伸加工：超過拉伸加工極限的拉伸加工產(chǎn)品，需要經(jīng)過兩次以上的多次拉伸方能完成。經(jīng)過前工位深度方向拉伸加工的產(chǎn)品，在深度方向進行再拉伸加工。寬凸緣拉伸件，***次拉伸時就拉伸成所要求的凸緣直徑，在其后再拉伸時，凸緣直徑保持不變。</p><p> ①控制機械的運動，如內(nèi)燃機中的閥門彈簧片、離合器中的控制彈片等。 </p> <p> <br /> </p> <p> ②吸收振動和沖擊能量，如汽車、火車車廂下的緩沖彈片、聯(lián)軸器中的吸振彈片等。 </p> <p> <br /> </p> <p> ③ 貯存及輸出能量作為動力，如鐘表彈片、***中的彈片等。 </p> <p> <br /> </p> <p> ④用作測力元件，如測力器、彈片秤中的彈片等。彈片的載荷與變形之比稱為彈片剛度，剛度越大，則彈片越硬。按受力性質(zhì)，彈片可分為拉伸彈片、壓縮彈片、扭轉(zhuǎn)彈片和彎曲彈片，按形狀可分為碟形彈片、環(huán)形彈片、板彈片、螺旋彈片、截錐渦卷彈片以及扭桿彈片等。 </p> <p> <br /> 下面和禾聚精密五金廠小編一起來看下沖壓拉伸件防腐處理方法。</p><div
