style="text-indent:25px">變薄拉伸加工：與普通拉伸不同，變薄拉伸主要是在拉伸過程中改變拉伸件筒壁的厚度。凸凹模之間的間隙小于毛坯厚度，毛坯直壁部分在通過間隙時，處于較大的均勻壓應(yīng)力之下，拉伸過程中壁厚變薄的同時，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強度。面板拉伸加工：面板產(chǎn)品是板材沖壓件，表面形狀復(fù)雜。在拉伸工序中，毛坯變形復(fù)雜，其成形性質(zhì)已非簡單的拉伸成形，而是拉深與脹形同時存在的復(fù)合成形。逆向拉伸加工：將前工序的拉伸工件進(jìn)行反向拉伸，工件內(nèi)側(cè)變成外側(cè)，并使其外徑變小的加工。聚氨酯涂層是一種為適應(yīng)環(huán)保需求而研制開發(fā)的一種新型綠色特殊涂層，有良好的耐磨和耐腐蝕性。中山精密拉伸五金件加工廠</p><p
