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(xiàn)形及其他不規(guī)則形狀的薄壁零件。接下來(lái)，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(duì)圓錐(或角錐)形容器、半球形容器及拋物線(xiàn)面容器等的拉伸加工，其中還包含擴(kuò)形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對(duì)一次拉伸加工無(wú)法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進(jìn)行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> 龍華沖壓精密拉伸五金件模具技術(shù)特點(diǎn)：拉伸公差可達(dá)±0.015mm、外觀(guān)無(wú)瑕疵、可做到R/T＜1.0。</p><div

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(guò)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(guò)間隙時(shí)，處于較大的均勻壓應(yīng)力之下，拉伸過(guò)程中壁厚變薄的同時(shí)，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強(qiáng)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(jiǎn)單的拉伸成形，而是拉深與脹形同時(shí)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。</p><p> 沖壓拉伸件在生產(chǎn)的過(guò)程中需要做好防腐處理，這樣可以有效地避免在使用過(guò)程中發(fā)生腐蝕現(xiàn)象，下面和禾聚精密五金廠(chǎng)小編一起來(lái)看下沖壓拉伸件防腐處理方法。 </p> <p> <br /> </p> <p> 1、瀝青漆涂層，噴漆前對(duì)沖壓拉伸件進(jìn)行預(yù)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> 6、聚氨酯涂層是一種為適應(yīng)環(huán)保需求而研制開(kāi)發(fā)的一種新型綠色特殊涂層，有良好的耐磨和耐腐蝕性。 </p> <p> <br /> 例如同等的拉伸高度，如果選擇塑性比較差的金屬材料，就需要用更多的拉伸步距或中途退火。</p><div style="width:100%;text-align: center;"><img style="max-width:
