style="text-indent:25px">與普通拉伸不同，龍華質(zhì)量精密拉伸五金件加工廠，變薄拉伸主要是在拉伸過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間隙時，處于較大的均勻壓應(yīng)力之下，拉伸過程中壁厚變薄的同時，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強度面板產(chǎn)品是板材沖壓件，表面形狀復雜。在拉伸工序中，龍華質(zhì)量精密拉伸五金件加工廠，毛坯變形復雜，其成形性質(zhì)已非簡單的拉伸成形，而是拉深與脹形同時存在的復合成形五金沖壓拉伸成型作為主要的沖壓工序之一，應(yīng)用非常***，龍華質(zhì)量精密拉伸五金件加工廠。用拉伸工藝可以制成各種圓筒形、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</p><div

拉伸件的種類很多，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)律等都有相當大的差別，有些甚至是本質(zhì)上的區(qū)別。 1、拉伸過程中，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變菜。當變形程度較大時，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，冷作硬化嚴重，故硬度較高；而底部變形程度小，冷作硬化小，故度也低。</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/370225.html</p></div></div></div></div></div><div id="mbifhjl" class="page-right
