拉深件的工序數(shù)量與材料性質(zhì)、拉深高度、拉深階梯數(shù)以及拉深直徑、材料厚度等條件有關(guān)，需經(jīng)拉深工藝計(jì)算才能確定。當(dāng)拉深件圓角半徑較小或尺寸精度要求較高時(shí)，則需在拉深后增加一道整形工序，精密小五金拉伸件工藝大致可分為分離工序和成形工序。 </p> <p> <br /> </p> <p> 分離工序是在沖壓過(guò)程中使其與坯料沿一定的輪廓線相互分離，同時(shí)五金沖壓件分離斷面的質(zhì)量也要滿足一定的要求。 </p> <p> <br /> </p> <p> 成形工序是使沖壓坯料在不破壞的條件下發(fā)生變形，并轉(zhuǎn)化成所要求的五金沖壓件形狀，同時(shí)也應(yīng)滿足尺寸公差等方面的要求。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">精密拉伸件市場(chǎng)應(yīng)用*** 拉伸件的種類(lèi)很多，由于其形狀不同，其變形區(qū)的位置、變形的性質(zhì)、坯料各部分的應(yīng)力應(yīng)變狀態(tài)和分布規(guī)律等都有相當(dāng)大的差別，有些甚至是本質(zhì)上的區(qū)別。 1、拉伸過(guò)程中，坯料的凸緣部分是主要變形區(qū)，其余部分只發(fā)生少量變形，但要承受并傳遞拉伸力，故是傳力區(qū)； 2、變形區(qū)受切向壓應(yīng)力和徑向拉應(yīng)力作用，產(chǎn)生切向壓縮和徑向伸長(zhǎng)變菜。當(dāng)變形程度較大時(shí)，變形區(qū)主要發(fā)生失穩(wěn)起皺現(xiàn)象。 3、拉伸件的壁厚不均勻，口部壁厚略有增厚，底部壁厚略有減薄，靠近底部圓角處變薄嚴(yán)重； 4、拉伸件各部分硬度也不一樣，口部變形程度大，冷作硬化嚴(yán)重，故硬度較高；而底部變形程度小，冷作硬化小，故度也低。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><div style="width:100%;text-align:

2、橢圓拉伸加工：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。3、矩形拉伸加工：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。4、山形拉伸加工：沖壓件的側(cè)壁為斜面時(shí)，側(cè)壁在沖壓過(guò)程中是懸空的，不貼模，直到成形結(jié)束時(shí)才貼模。成形時(shí)側(cè)壁的不同部位變形特點(diǎn)不完全相同。精密拉伸沖壓中，鋁合金拉伸件是比較難加工的。光明本地精密拉伸五金件價(jià)格多少</p><p
