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(diǎn)是一次成型，可以提高生產(chǎn)效率，缺點(diǎn)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(yīng)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> 毛坯與凸凹模中心不合或五金拉深件沖壓材料厚度不均勻，以及凹模圓角半徑和凸凹模間隙不均勻，凹模圓角半徑太大，在拉深的***階段脫離了壓邊圈，使尚未越過圓角的材料壓邊圈壓不到起皺后被拉入凹模形成口緣褶皺。 </p> <p> <br /> </p> <p> 五金拉深件邊緣不平對(duì)策： </p> <p> <br /> </p> <p>

/> </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 /> 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)。龍崗耐磨精密拉伸五金件哪里好</p><p style="text-indent:25px">精密拉伸沖壓中，鋁合金拉伸件是比較難加工的。南山金屬精密拉伸五金件價(jià)格多少</p><p style="text-indent:25px">圓筒拉伸加工（Round drawing）：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(duì)稱，在同一圓周上變形均勻分布，法蘭上毛坯產(chǎn)生拉深變形橢圓拉伸加工（Ellipse drawing）：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矩形拉伸加工（Rectangular drawing）：一次拉伸成形的低矩形件。拉伸時(shí)，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。南山金屬精密拉伸五金件價(jià)格多少</p><p
