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(fù)合成形。壓料面上坯件的變形為拉伸變形（徑向為拉應(yīng)力，切向為壓應(yīng)力），而輪廓內(nèi)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(yīng)力）。東莞質(zhì)量精密拉伸五金件的用途和特點誘發(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><div

選擇拉伸材料中，要注意屈服點、抗拉強度的比值越小，拉深性能越好，一次變形的極限程度越大越有利于降低成本以及保證拉伸的質(zhì)量。不銹鋼拉伸是拉伸工藝中經(jīng)常見到的，很多拉伸件經(jīng)常用到不銹鋼。但由于不銹鋼的延展率比較小，彈性模量也比較大，硬化**比較高。拉伸時會出現(xiàn)開裂有時會出現(xiàn)拉伸變形后；有時會在拉伸件由凹模內(nèi)退出的時候發(fā)生；有時在拉伸變形后受到撞擊或者振動時才出現(xiàn)；有時在拉伸變形后經(jīng)過一段時間的存放或者使用中出現(xiàn)開裂。 </p> <p> <br /> </p><p style="text-indent:25px">五金沖壓拉伸成型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)則形狀的薄壁零件圓帶凸緣(法蘭)圓筒產(chǎn)品的拉伸。法蘭與底部均為平面形狀，圓筒側(cè)壁為軸對稱，在同一圓周上變形均勻分布，法蘭上毛坯產(chǎn)生拉深變形法蘭上毛坯的變形為拉伸變形，但變形量與變形比沿輪廓形狀相應(yīng)變化。曲率越大的部分，毛坯的塑性變形量就越大;反之，曲率越小的部分，毛坯的塑性變形越小。不銹鋼拉伸中導(dǎo)致開裂形成的原因有。</p><div
