Convenient Route

Tube drawing is a convenient route to manufacture near net tubular product with high accuracy. In this paper, the tube drawing process was investigated through finite element method. The metal flow rule of tube drawing and influence of mold conical angle on the drawing force and equivalent strain during tube drawing process were studied. The reasonable mold conical angle was obtained from the simulated results.

Element Simulation

In this paper the drawing process of Box-torque was simulated by Dynaform, which is FEM simulation software. The process parameters, which affected the quality of forming, were optimized by finite element simulation. The emphasis was focus on the optimization of draw-bead and BHF and data were summarized from the optimization graphs. In this simulation, lengthways draw-bead was set on the technical face for reducing or eliminating wrinkle. It was innovation difference from the usual that the draw-bead was set on binder. Finally the correctness of simulation was approved by comparing the optimization of simulation with the data of experimentation.

Element Simulation

In order to investigate the deformation behavior of a plate during a vertical-horizontal rolling process, a thermo-mechanical coupling analysis is carried out by three-dimensional (3-D) rigid-plastic FEM to simulate the process. The metal flow and the shape evolution of the plate are focused during this investigation. The thickness and the width of the plate agree well with the measured values.
