Blow Molding Process Optimization of Amorphous Alloy Tube Blank Based on POLYFLOW Software
Aimed at Zr44Ti11Cu10Ni10Be25 amorphous alloy and based on POLYFLOW software, studies the influence of die inlet diameter, blowing pressure and die transition fillet on the blow molding performance of tube blank systemly, and raises a new evaluation index to evaluate the formability of amorphous tube blank, limit height to diameter ratio (LHTDR) . The simulation results indicate that the forming limit of tube blank can be multiple improved with the decrease of die inlet diameter, blowing pressure has a significant effect on the forming limit which can be improved by decreasing the pressure, and the larger of the die transition fillet the higher of the forming limit in certain range. Finally, a set of reasonable process parameters is given which has great significance for guiding the formulation of blow molding process scheme.
