METHOD FOR STAMPING SHAPED ELEMENTS OF METAL SHEET AND UNIT FOR STAMPING SHAPED ELEMENTS OF METAL SHEET

摘要

The subject of the invention is a method for stamping of shaped elements of metal sheet and a unit for stamping of shaped elements of metal sheet, which is used for the stamping of metal sheet elements in the process of construction of products made by spinning. Characterized in that a metal sheet (12) is placed on a rotating stencil (1), with a shaped frontal surface, and pressed with a blank holder (2) with a shaped frontal surface with an outline corresponding to the outline of the frontal surface of the stencil (1) for shaping the outline of the bottom, and to the top edge of the rotating stencil (1) from the side of the punch (2) at least one shaping roller (9) is pressed, which moves with a continuous and/or oscillatory movement along the edge of the metal sheet (12), at a distance from the external surface of the stencil (1) determined by the thickness of the sheet (12). The method is implemented in a device, characterized in that the frontal surfaces of the stencil (1) and the blank holder (2) are surfaces which are shaped to fit each other, moreover at least on one side of the body (5) a support (8) is placed, on which a shaping roller (9) is mounted with a pressure and control mechanism (10).
