Abstract (en)
[origin: DE102007019173B3] Method for press-forming and hardening a steel workpiece in a stamping machine comprises partially moving the stamps (2, 3) away from each other after deforming and passing coolant (6) through the gap (10, 11) between the stamps and the workpiece. The heated workpiece is placed into the molding hollow space (9) above the coolant meniscus (8). The coolant meniscus is raised high enough for the coolant to flow into the hollow space.
