From the furnace into the press

Description

Production lines for press hardening combine advance furnace technology, hydraulic press technology, precise controls and rugged automation systems.  Thus, after heating in a rotary hearth furnace the blanks are picked up by a robot or transfer system and placed on the die of the hydraulic press.  Here the actual forming process takes place.  The controlled cool-down to ensure consistent hardening of the parts likewise takes place in the water-cooled die as well as in a downstream cooling zone.  Capacities of the hydraulic presses used here range between 6,000 and 12,000 kN.  Trimming of the finished parts takes place in mechanical blanking presses with integrated dampening systems (Soft-Shock technology) as well as in laser cells.
The technology of form hardening for autobody parts is making strong gains among automakers and their suppliers worldwide.  The reasons for this popularity include growing demands for passenger safety and lowering of permissible limits for CO^₂ emissions, both measures which require weight reduction and simultaneous improvement of the tensile strength of the autobody parts.
