Metal Flow Behavior on the Non-Uniform Wall Thickness Three-Way Valve Extrusion

Abstract:

High pressure valve always takes several dozens to several hundreds MPa pressure and which was difficulty to form because of its complex internal structure. In this paper, three-dimensional numerical simulation was carried out to investigate metal flow behavior during the three-way valve extrusion process. The block shape materials were formed to shell shape three-way components by the level and vertical direction uniform temperature simultaneous extrusion. The simulation results show that the metal flows were influenced by both loading sequence and time of the moving die of two directions. The loading process worked out through dynamic simulation can guide the actual processing.
