我們都知道拉伸是主要的沖壓工序之一，其應(yīng)用***。用拉伸工藝可以制成圓筒形、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。接下來，小編就為您介紹下五金沖壓拉伸成型加工工藝。 </p> <p> <br /> </p> <p> 1、拉伸加工：使用壓板裝置，利用凸模的沖壓力，將平板材的一部分或者全部拉入凹模型腔內(nèi)，使之成形為帶底的容器。容器的側(cè)壁與拉伸方向平行的加工，是單純的拉伸加工，而對圓錐(或角錐)形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> 中山質(zhì)量精密拉伸五金件廠家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(nèi)應(yīng)力從而產(chǎn)生廢品。</p><div

不銹鋼拉伸中導(dǎo)致開裂形成的原因有：奧氏體不銹鋼的冷作硬化**高；奧氏體不銹鋼為亞穩(wěn)定型，在變形時會出現(xiàn)變相，誘發(fā)馬氏體相；馬氏體相又脆，因此會容易出現(xiàn)開裂。在塑性變形中，隨著變形量的增加，誘發(fā)馬氏體含量也會隨著變形量的增加而增高，殘余應(yīng)力則越大，殘余應(yīng)力和馬氏體含量的關(guān)系：誘發(fā)馬氏體相含量增高，引發(fā)殘余的應(yīng)力越大，在沖壓過程中便容易開裂。 </p> <p> </p> <p> 造成表面劃痕的因素有：不銹鋼拉伸件的表面會出現(xiàn)劃痕是由于工件與模具表面存在相對的移動，在一定的壓力促使下，導(dǎo)致坯料和模具局部表面直接產(chǎn)生摩擦，加之坯料的變形熱使得坯料和金屑熔蓋在模具的表面上，使工件外表擦傷產(chǎn)生劃痕。 </p> <p> <br /> </p><p style="text-indent:25px">工藝參數(shù)指制定工藝方案所依據(jù)的數(shù)據(jù)，如各種成形系數(shù)(拉深系數(shù)、脹形系數(shù)等)、零件展開尺寸以及各種應(yīng)力等。計算有兩種情況，第一種是工藝參數(shù)可以計算得比較準確，如零件排樣的材料利用率、工件面積等；第二種是工藝參數(shù)只能作近似計算，如一般彎曲或拉深成形力、復(fù)雜零件坯料展開尺寸等，確定這類工藝參數(shù)一般是根據(jù)經(jīng)驗公式或圖表進行粗略計算，有些需通過試驗調(diào)整選擇拉伸設(shè)備根據(jù)要完成的工序性質(zhì)和各種設(shè)備的力能特點，考慮所需的變形力和尺寸大小等主要因素，結(jié)合現(xiàn)有設(shè)備情況來合理選定設(shè)備類型和噸位。瀝青漆涂層，噴漆前對沖壓拉伸件進行預(yù)熱可以提高瀝青漆的附著力，加速干燥。</p><div

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。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。中山質(zhì)量精密拉伸五金件廠家</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)。 </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，一般都可以查表進行大概計算。 </p> <p> <br /> 中山質(zhì)量精密拉伸五金件廠家</p><p
