A forming tool and a method for hot forming and partially press hardening a workpiece, wherein the workpiece is heated prior to forming and is subsequently hot formed in a forming tool including a die, a punch, and a cooling device. When the forming tool is closed, the contact between the workpiece and the contact surfaces of the die and the punch of the forming tool is interrupted by moving apart a movable die part and a movable punch part. The die includes a first die part and at least one second die part which is movable relative to the first die part. The punch includes a first punch part and at least one second punch part which is movable relative to the first punch part. The at least one movable second die part and the at least one movable second punch part interact with an opening device.
A method for hot forming and partially press hardening a workpiece made of sheet steel, in which the workpiece is heated prior to forming and is subsequently hot formed in a forming tool comprising a die having at least a first die part and a second die part for forming the workpiece, a punch having at least a first punch part and a second punch part for forming the workpiece, and a cooling device, the method comprising:
