Experimental Study on Composite Deformation of Drawing-Flanging for Axisymmetric Holed Slab
The experimental study on the influencing regularity of the technological parameters to the deformed tendency & the forming load during drawing forming axisymmetric holed slab was carried out. The influence of the pre-punched hole size, and punching stroke o n the deformed tendency & their r elation with the forming load were analyzed. Result of experiment can be used as basic consideration for the process design of drawing after hole punching and the techno logical measures to punch technological hole for releasing stress at the region difficult to form to improve the deformation degree.
