摘要:

 

 
为了实现3A21铝合金小角度锥形件成形,采用多道次普强复合旋压和预成形后旋压两种工艺方法,研究了坯料尺寸、旋轮圆角半径、旋轮间隙等工艺参数对旋压结果的影响规律。结果表明,多道次普强复合旋压时,坯料相对厚度越小,减薄破裂、凸缘失稳起皱的趋势越明显;旋压后材料壁厚的变化呈U字形,两端厚,达到7 mm左右,中间薄,只有5 mm左右;贴模性较差,最大间隙达到0.9 mm。通过预成形和剪切旋压相结合的方式,坯料不会产生失稳开裂的现象,壁厚控制更精确,得到旋压件侧壁的壁厚在7 mm左右,而口部的壁厚达到11 mm左右;旋压件贴模间隙很小,只有0.2 mm左右。
 

 

 
In order to realize the forming of 3A21 aluminum alloy conical parts with small angle, two methods of multi-pass general strength composite spinning and preforming spinning were adopted, and the influence laws of process parameters such as blank size, wheel fillet radius and wheel clearance on the spinning results were studied. The results show that during the multi-pass general strength composite spinning, the smaller the relative thickness of billet is, the more obvious the trend of the thinning and cracking and the instability and wrinkling of flanges is. After spinning, the change of material wall thickness is U-shaped, and the thickness at both ends is about 7 mm as well as the thickness in the middle is only about 5 mm. However, the part is not well fitted to the die, and the maximum clearance is up to 0.9 mm. Through the combination of preforming and shear spinning, the blank will not produce the phenomenon of instability cracking, and the wall thickness is controlled more accurately. Thus, the wall thickness of the side wall for spinning part is about 7 mm, the wall thickness of mouth is about 11 mm, and the clearance between spinning part and die is very small with only about 0.2 mm.
