精密拉伸沖壓中，鋁合金拉伸件是比較難加工的，但是在加工中注意某些問(wèn)題點(diǎn)就可以很順利的完成加工了。 </p> <p> </p> <p> 鋁合金拉伸件加工注意事項(xiàng)有：在取料、移動(dòng)、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(duì)容易折彎、出料長(zhǎng)短的鋁合金材料要及時(shí)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(jìn)行拉伸加工，溫度過(guò)高會(huì)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(yīng)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(xì)、形狀奇怪等鋁合金材料的小腳、薄齒、長(zhǎng)腿、圓弧面、傾斜面、開(kāi)口、視點(diǎn)等受力情況，避免材料部分或者點(diǎn)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(guò)程中需根據(jù)原材料的出料實(shí)際情況與各種具體需求加以調(diào)整。在相互對(duì)立的技能需求中尋找滿(mǎn)足各種具體需求的拉伸量。 </p> <p> <br /> 加之坯料的變形熱使得坯料和金屑熔蓋在模具的表面上，使工件外表擦傷產(chǎn)生劃痕。金屬精密拉伸五金件加工</p><p
