2、橢圓拉伸加工：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。3、矩形拉伸加工：一次拉伸成形的低矩形件。拉伸時，凸緣變形區(qū)圓角處的拉伸阻力大于直邊處的拉伸阻力，圓角處的變形程度大于直邊處的變形程度。4、山形拉伸加工：沖壓件的側(cè)壁為斜面時，側(cè)壁在沖壓過程中是懸空的，不貼模，直到成形結(jié)束時才貼模。成形時側(cè)壁的不同部位變形特點不完全相同。坪山?jīng)_壓精密拉伸五金件廠家誘發(fā)馬氏體含量也會隨著變形量的增加而增高。</p><div

</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。一次拉伸的特點是一次成型，可以提高生產(chǎn)效率，缺點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 /> </p><p style="text-indent:25px">丘形拉伸加工：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合成形。壓料面上坯件的變形為拉伸變形(徑向為拉應力，切向為壓應力)，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力)。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重變薄，或曲面部分的失穩(wěn)起皺。沖壓拉伸件在生產(chǎn)的過程中需要做好防腐處理。</p><div

drawing）：將左側(cè)初拉伸產(chǎn)品進行再拉伸加工，成形為右側(cè)的臺階形底部。深度較深的部分在拉伸成形的初期就產(chǎn)生變形，深度較淺的部分在拉伸的后期產(chǎn)生變形。在臺階變化部分的側(cè)壁易誘發(fā)切應力產(chǎn)生變形環(huán)氧煤瀝青涂層是一種雙組分涂層，該涂層具有較高的附著力和非常光滑的表面。坪山防腐精密拉伸五金件價格多少</p><p
