中文摘要:针对某7A04合金筒件的缩口结构,根据筒件缩口形状特点,结合7A04合金成形特性,设计了等温成形工艺方案和工艺工装,在此基础上进行了相应的工艺试验研究。结果表明,通过此工艺和模具,筒件缩口达到了要求尺寸,且缩口变形部位未出现裂纹、起皱等缺陷,成形效果好,从而为铝合金筒件缩口成形技术的应用提供了参考。
英文摘要:Aiming at the necking structure of 7A04 alloy aluminum can, combining with the characteristics of necking shape and 7A04 alloy forming process, the isothermal forming process scheme and die was designed, in the meantime, the necking experiment was carried out. The results indicate that the sizes of necking attain goal at suitable process scheme and die, there are no flaws like cracks, wrinkling and so on, which provides references for the application of necking forming process of aluminum alloy can
