Method for producing a shaped sheet metal part having wall thicknesses differing from each other by region, and axle subframe

摘要

A method for producing a shaped sheet metal component having wall thicknesses differing from each other is disclosed including providing a sheet metal material having a constant wall thickness, pre-shaping the sheet metal material into a preform by means of a hold-down press, producing at least one bulge in an inner region such that the material is stretched and has a reduced wall thickness, flattening and/or extending the produced preform, cutting the sheet metal material in order to form a blank before, during, or after the pre-shaping, and shaping the blank into the shaped sheet metal component.
