產(chǎn)品的質(zhì)量和性能與其生產(chǎn)過程密不可分。為了保證產(chǎn)品質(zhì)量，有必要控制生產(chǎn)過程。以沖壓拉伸模為例。在生產(chǎn)中，其生產(chǎn)過程一般具有以下特點： </p> <p> <br /> </p> <p> 1.沖壓拉伸件模具可用于加工尺寸范圍大、形狀復(fù)雜的零件，如鐘表等小秒表、汽車縱梁、覆蓋件等。由于沖壓過程中材料的冷變形和硬化效應(yīng)，沖壓的強度和剛度較高。 </p> <p> <br /> </p> <p> 2.沖壓時，模具保證了沖壓件尺寸和形狀的準確性，一般不會損壞沖壓件的表面質(zhì)量，模具使用壽命長。因此，沖壓質(zhì)量穩(wěn)定，互換性好，具有“一模一樣”的特點。 </p> <p> <br /> </p> <p> 3.沖壓一般不產(chǎn)生切屑，材料消耗少，不需要其他加熱設(shè)備，是一種節(jié)省材料和能源的加工方法，沖壓件成本較低。 </p> <p> <br /> </p> <p> 4.本發(fā)明生產(chǎn)效率高，操作方便，易于實現(xiàn)機械化和自動化。這是因為沖壓是通過沖壓模具和沖壓設(shè)備來完成的。普通壓力機的沖程數(shù)可達到每分鐘幾十次，高速壓力可達到每分鐘幾百次甚至幾千次，每個沖壓沖程可獲得一個沖頭。 </p> <p> <br /> 珠海質(zhì)量精密拉伸五金件哪里好便于散熱均勻，從而減少橫向亮斑。</p><div

src="https://tyunfile.71360.com/UploadFile/mfq123/637280074021494141/8351680.png"></div><p> 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、拋物線形及其他不規(guī)則形狀的薄壁零件。接下來，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，而對圓錐(或角錐)形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> </p><p> 開毛坯料 </p> <p> <br /> </p> <p> 一般規(guī)則且形狀簡單的回轉(zhuǎn)體拉伸產(chǎn)品，大部分都屬于非變薄拉伸，可以直接根據(jù)其拉伸前、后面積不變原則進行確定。如果是形狀非常復(fù)雜的拉伸件，有時可能材料會出現(xiàn)嚴重的流動而變薄，一般無法精確計算其開料尺寸，都是事先用3D展開預(yù)估，也就是所謂的試料"多則皺，少則裂”，按此方法判斷材料的流動情況。辦法有：調(diào)整壓邊圈的壓力、增加拉深筋、改變上下模鑲件的圓弧過度半徑、工件上切工藝口等。 </p> <p> <br /> </p> <p> 拉伸件總之是比較有技術(shù)含量的模具類型，不管是對設(shè)計、加工、組裝、還是調(diào)試都是一個挑戰(zhàn)，需要十分謹慎。 </p> <p> <br /> 殘余應(yīng)力則越大，殘余應(yīng)力和馬氏體含量的關(guān)系。</p><div style="width:100%;text-align:

拉伸件成型沖壓加工是禾聚精密的六大技術(shù)之一，技術(shù)特點：拉伸公差可達±0.015mm、外觀無瑕疵、可做到R/T＜1.0。拉伸件應(yīng)用于機械、電子、電器、儀表、汽車、航空、**產(chǎn)品。 </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(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 />
