</p> <p> 1、瀝青漆涂層，噴漆前對沖壓拉伸件進行預熱可以提高瀝青漆的附著力，加速干燥。 </p> <p> <br /> </p> <p> 2、水泥砂漿內(nèi)襯加特殊涂層，可以提高沖壓拉伸件內(nèi)襯的抗腐蝕能力。 </p> <p> <br /> </p> <p> 3、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。 </p> <p> <br /> </p> <p> 4、環(huán)氧陶瓷內(nèi)襯由于制造工藝難度大，成本高，所以在使用上有一定的局限性，具有很高的附著力和光潔度，是一種沖壓件防腐蝕涂層。 </p> <p> <br /> </p> <p> 5、鋁酸鹽水泥涂層或***鹽水泥涂層，這兩種特殊水泥涂層均適用于沖壓拉伸件的內(nèi)防腐，提高抵抗侵蝕的能力。 </p> <p> <br /> </p> <p>

數(shù)字越大，公差等級（加工精度）越低，尺寸允許的變動范圍（公差數(shù)值）越大，加工難度越小</p><p 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，表面形狀復雜。在拉伸工序中，毛坯變形復雜，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合成形。逆向拉伸加工：將前工序的拉伸工件進行反向拉伸，工件內(nèi)側(cè)變成外側(cè)，并使其外徑變小的加工。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。</p><div

鋁合金拉伸件加工注意事項有：在取料、移動、拉伸中材料不能相互碰擦，堆疊以及纏繞等，相互之間要留有一定的空隙。對容易折彎、出料長短的鋁合金材料要及時處理。 </p> <p> </p> <p> 原材料要冷卻到50°以下才能移到拉伸架上進行拉伸加工，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)應力從而產(chǎn)生廢品。 </p> <p> <br /> </p> <p> 由于毛條有阻熱效果，裝飾外表需求高的鋁合金材料要多翻轉(zhuǎn)，便于散熱均勻，從而減少橫向亮斑。 </p> <p> <br /> </p> <p> 要注意寬厚比較高，弧度大、壁厚細、形狀奇怪等鋁合金材料的小腳、薄齒、長腿、圓弧面、傾斜面、開口、視點等受力情況，避免材料部分或者點狀尺度變形、扭曲、螺旋等。 </p> <p> <br /> </p> <p> 拉伸量要控制在百分之一的擺布，沖壓過程中需根據(jù)原材料的出料實際情況與各種具體需求加以調(diào)整。在相互對立的技能需求中尋找滿足各種具體需求的拉伸量。 </p> <p> <br /> 汕頭金屬精密拉伸五金件工廠</p><p
