Description:
Taking the 21-6-9 (0Cr21Ni6Mn9N) high strength stainless steel tube (HSSST) of 15.88 mm × 0.84mm (diameter D × wall thickness t ) as the objective, a three dimensional (3D) elastic plastic finite element (FE) model of the whole process of the 21-6-9 HSSST in numerical control (NC) rotary draw bending was established based on ABAQUS explicit/implicit code, and its reliability was validated. Then, the effects of process parameters on springback of the 21-6-9 HSSST in NC rotary draw bending were studied using the FE simulation based on orthogonal test. The results show that the effects of process parameters on springback angle and radius form high to low are the clearance between tube and wiper die C w , mandrel extension length e , clearance between tube and mandrel C m , friction coefficient between tube and wiper die f w , clearance between tube and pressure die C p , friction coefficient betw...
