Title:
ALUMINUM ALLOY ELECTRICAL PULSE QUENCHING FORMING PROCESS AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/205362
Kind Code:
A1
Abstract:
A novel aluminum alloy electrical pulse quenching forming process and device, the device comprising an AC power source (7), positive and negative electrodes of the AC power source (7) respectively contacting an aluminum alloy plate (3) by means of two electrical brushes (5) and (6), such that in a stamping process an electrical current continuously passes through the aluminum alloy plate (3). The process comprises applying an electrical pulse to achieve heating; heating the aluminum alloy plate (3) to a solid solution temperature and maintaining the temperature; sizing; constant-temperature cooling and storage; aging; placing the aluminum alloy plate (3) into an electrical pulse auxiliary forming device and performing stamping and maintaining a pressing force.
