Abstract：

Nosing of thin-walled tube with straight pipe by cone curved die was studied.The forming characteristics and laws of the neck position were formulated.The range of neck fillet radius was provided.The finite-element method was used for the analysis of nosing of aluminum performs and the simulation results of nosing these performs show that the formula to the problem is satisfactory,which provide technologists with some guidelines for process-planning and die-designing.
