ABSTRACT:
The invention relates to a method for producing hollow bodies such as nut elements to be fastened to components that usually consist of sheet metal. The invention especially relates to a method for producing hollow bodies with an at least substantially square or rectangular outline by cutting individual bodies from a profile in the form of a profile rod or a reel after respective holes have been punched into the profile, and optionally afterwards producing a threaded cylinder. The inventive method is further characterized in that before or after the punching of the profile a passage treatment is carried out in order to produce a cylindrical or annular projection, concentric to the punching or the intended punching, on the side of the profile facing the component by flow of material. The projection is optionally shaped to an annular punched section in an additional molding cycle. The invention further relates to various hollow bodies, assembly units and molds for producing said hollow bodies.
