Abstract
A method for forming a semi-finished product is disclosed, wherein the semi-finished product is provided in a provision step and, in a solid-stock forming step, a forming region of the semi-finished product is formed such that a thickness of the deformed forming region increases continuously toward one margin of the semi-finished product.
Claims10
A method for forming a product, comprising:
- providing a blank to form the product in a provision step;
- forming the blank in a forming step via a forming tool punch, wherein a thickness of the formed blank is substantially constant, and wherein the forming step creates a bend in the blank in a forming region of the blank;
- and
- forming the forming region of the blank in a solid-stock forming step via an edge forming punch different than the forming tool punch by moving the edge forming punch in a direction towards the forming tool punch,
- wherein, during the solid stock forming step, the forming region of the blank is formed such that a thickness of a deformed forming region increases continuously and tapers in increasing thickness toward one margin of the product, and
- wherein the forming step is carried out after the provision step, while the solid-stock forming step is carried out after the forming step.

A device for forming a product comprising a molding tool, the molding tool comprising:
- a forming tool punch;
- and
- an edge forming punch,
- wherein the molding tool is adapted to:
- form a blank with the forming tool punch, wherein a thickness of the formed blank is substantially constant, and wherein forming the blank creates a bend in the blank in a forming region of the blank;
- and
- deform the blank forming the product with the edge forming tool, by moving the edge forming punch in a direction towards the forming tool punch, to form the forming region of the blank such that a thickness of the deformed forming region increases continuously and tapers in increasing thickness toward one margin of the product,
- wherein the molding tool is adapted to deform the blank to form the forming region after the forming step.
