Analysis of Forward Spinning for Aluminium Alloy Tube
In order to obtain actual preferred principle of processing parameter about three-roller forward spinning of aluminium alloy tube, take the aluminium alloy tube that spun by Jiangyang chemical plant as a research object, based on nonlinear FEA software ANSYS/LS-DYNA, carried on 3D dynamic simulation, spinning force and stress-strain analysis to three-roller forward spinning of aluminium alloy tube under different processing parameter. Analysis results indicate: When feeds of spinning roller take 0.66mm/r~1.58mm/r(except 0.97mm/r), spinning force, component forces of spinning force, stress and strain have minimal change. Rounded angle radius of spinning roller should be greater than 60% and less than 125% blank thickness of aluminium alloy tube. Forming angle of spinning roller should take 22°~24°. Diameter of spinning roller should take 220mm~240mm. The conclusion has important meaning to further studies and actual manufacture about three-roller forward spinning of aluminium alloy tube.
