Abstract: In bending with PUR pad, profile with different curvature radius can be manufactured. Experiment of trough-shaped profile was carried out to investigate the effect of section shape, penetration depth, roller radius and PUR pad thickness. Results show that both the position of neutral surface and section moment of bending have significant effect on curvature radius. Profile with bigger section moment of bending is difficult to bend. Curvature radius of bent profile decrease sharply when penetration depth increase. Change of roller radius has similar effect as the position of neutral surface. PUR pad thickness has big effect under small penetration depth.

Keywords: aluminium alloys; trough-shaped profile; bending; section shape; penetration depth; roller radius; PUR pad thickness; polyurethane pad; curvature radius.
