| Abstract: | In view of that the tube die forgings are long, thin and difficult to be forged, a multi-step and sectional forming method was proposed in which the super long tube die forgings can be made by short core shaft. The drawing process was analyzed by computer simulation technology and the reasonable drawing parameters were determined. |
