Abstract:
A method of connecting workpieces with a press tool, the press tool having at least two press jaws, the at least two press jaws having partially cylindrical inside surfaces and being connected together by at least one bearing bolt, the method comprising the following steps:opening the press tool by pivoting the at least two press jaws about the at least one bearing bolt; surrounding the workpieces with the press tool; exerting cold-forming forces on the workpieces with the at least two press jaws by introducing a drive force on one or more of the at least two press jaws to close the press tool on the workpieces; and preventing formation of a flash on an outside surface of the workpieces between end faces of the press jaws by forming a bevel on an inside surface of one or more of the press jaws adjacent the end face such that the bevel is angled outward relative to the outside surface of the workpieces when the press tool is closed about the workpieces.
