  • Patent number: 10022769
    Abstract: A method for producing a shaped part from an aluminum sheet that includes an aluminum alloy, in particular an aluminum alloy of the 5000 series. The method includes introducing at least one aluminum sheet in a forming tool and cold-forming the aluminum sheet in the forming tool, and heating the cold-formed aluminum sheet at least once at least in some regions and at least once further metal forming the aluminum sheet. In order to create advantageous conditions for the method, it is proposed for the heated aluminum sheet to be subjected to the further metal forming step even before a temperature has been reached which the aluminum sheet has during the cold forming thereof.

  • Patent number: 8181331
    Abstract: The invention relates to a method for producing hardened structural parts from sheet steel. The method includes shaping at least one shaped part made of sheet steel provided with a cathodic corrosion protection coating, performing any required final trim of the shaped part and possibly any required punching, or the creation of a perforation pattern, subsequently heating the shaped part, at least over partial areas, under the admission of atmospheric oxygen to a temperature which permits austenizing of the steel material, and thereafter transferring the structural part to a mold-hardening tool and performing mold-hardening in the mold-hardening tool, wherein the structural part is cooled by the contact with and pressing by the mold-hardening tool and is hardened thereby.

    Abstract: The invention relates to a method for producing a shaped part from an aluminum sheet comprising an aluminum alloy, in particular an aluminum alloy of the 5000 series, wherein at least one aluminum sheet is introduced in a forming tool and cold-formed by the same, and in a further step, or in further steps, the cold-formed aluminum sheet is heated at least once at least in some regions and at least once further formed. In order to create advantageous conditions for the method, it is proposed for the heated aluminum sheet to be subjected to the further forming step even before a temperature has been reached which the aluminum sheet has during the cold forming thereof.
