内侧减薄拉深法加工光洁表面薄壁铝管的实验研究

Experimental research of forming thin wall aluminum tubewith smooth surface by inwall ironing method

对采用内侧减薄拉深法加工表面光洁薄壁铝管进行了实验研究 .实验结果表明 ,光洁效果决定于凹模内表面形貌在加工件上的复制作用 ,采用适当的减薄率、拉深速度和润滑油 ,可获得表面粗糙度低的表面光洁的薄壁铝管 ,实验装置合理 ,方法可行 .

Forming of thin wall aluminum tube with smooth surface by imwall ironing method was conducted in this paper. The experimental results indicate that thin wall aluminum tube with low surface roughness can be formed by using optimum thinning rate, drawing velocity and lubricant. Experimental device and forming method are resonable.
