Effect of Process Parameters on Hydroforming of Stainless Steel Tubular Components with Rectangular Section

摘要：

　　The effects of key process parameters including initial lengths of tube blank,forming velocity and loading paths on hydroformability of stainless steel tubular components with rectangular section were systematically investigated.The results showed that sufficient axial feed must be given before the tube contacting the surface of die in order to prevent the excessive thickness thinning,especially for longer tube blank.The lower loading velocity led to enhanced formability.It is more important that pulsating loading path observably improved the formability of 304 stainless steel.
