style="text-indent:25px">變薄拉伸加工（Ironing）：與普通拉伸不同，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拉伸加工（Panel

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(dāng)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(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。深圳耐磨精密拉伸五金件的用途和特點</p><p
