Abstract Scope |
In the hot stamping process suggested in the present study, the liquid CO2 served simultaneously as a quenching media for a high cooling rate and a lubricant to reduce seizures in stamping. For proper lubricating performance, an additive manufactured die with micro-holes was designed to directly supply the liquid CO2. There are three stages in the hot stamping with the liquid CO2. The aluminum 6061 alloy sheet was heated to solid heat treatment temperature during the heating stage. In the stamping stage, the liquid CO2 was supplied to provide lubrication between the workpiece and the die while the heated sheet was being deformed to the desired shape. Finally, the stamped sheet was quenched by the liquid CO2 and the die at the holding stage. The material property of the hot-stamped aluminum 6061 alloys was analyzed by the Vicker hardness test, and surface roughness test. |
