Patent ID: 8893540

Claim:
A method for producing a component formed from a thin-walled preform, the method comprising: placing the preform in a tool for forming the component, the preform consisting of a metal material and having a wall with a first height x and a first, radially measured wall thickness t 1 , wherein the tool comprises at least one inner wall support body, at least one outer wall support body, at least one upper punch and at least one lower punch for exerting a forming force and at least one die cavity for receiving material of the preform displaced during the forming step, closing the tool in such a way that the inner wall support body is positioned against an inner wall surface of the preform, and the outer wall support body is positioned against an outer wall surface of the preform, and the preform is enclosed between the upper punch and the lower punch, heating the preform at least one of before and during the forming step so that the forming step is one of a warm-forming and a hot-forming, and forming the preform into the component by an effect of the forming force of the punch, wherein the component comprises a support and a structure connected to the support and surrounding a support surface, at least in part, wherein, during the forming step, the wall of the preform is upset from the first height x to a second, smaller height b, and material of the wall of the preform substantially fills the at least one die cavity, and a corresponding radially measured wall thickness t 2 of the component is at least equal to the first wall thickness t 1 of the preform, and wherein material of the wall of the preform outside of the at least one die cavity is pushed into the at least one die cavity and the inner wall support body and the outer wall support body provide support and prevent buckling of the wall of the preform during the forming step.
