Abstract
Abstract This experimental study investigates the influence of sheet temperature and punch speed on blanking characteristics for aluminum alloy EN AW-5754, zinc and tin alloys, stainless steel 1.4301, press-hardened steel 22MnB5, and deep drawing grade DC06. Blanking experiments were conducted on a mechanical press. Circular blanks of 20 mm diameter with 5 % clearance were blanked with varied punch speed (0.1 m/s and 0.6–0.7 m/s depending on the sheet thickness) and varied initial sheet temperature (room-temperature, heated 50-80 °C, and cooled 0-(-30) °C). The maximum blanking force, blanking work, fracture shear stress, and the quality of the blanked edge were assessed. Experiments reveal that the sheet temperature has a strong effect on the blanking force. In the tested range, the punch speed primarily affects fracture initiation in steels, but has a negligible impact on non-ferrous alloys.
