Take a copper deep-hole and thin-wall cylindrical part as an example ,according to the characteristics of the thin-wall cylinders and deep-hole shape and accuracy require-ments ,the ironing process was analyzed .Combined with practical experience and the exist-ing equipment and technology ,three ironing processes were discussed .Some problems that should be paid attention to in the production design process were expounded .Moreover ,a die structure of ironing process was introduced . Mass production results shows that the forming process and die structure design are reasonable with simple operation ,and has high productivity .
