Metal sheet joint manufacturing method, involves forming collar by deformation at thin-walled material, where collar is formed for accommodating screw profile, and forming reinforcement profile surrounding collar at thin-walled material

摘要

The method involves forming a collar by deformation at a thin-walled material (102), where the collar is formed for accommodating a screw profile. A reinforcement profile surrounding the collar is formed at the thin-walled material, where the reinforcement profile is designed as a roof. The collar and the reinforcement profile are formed in a workpiece support. A through hole surrounded by the collar is formed. A reinforcement profile-embossing contour (112) is formed at an embossing stamp (110), which is coaxially arranged to another embossing stamp (104). Independent claims are also included for the following: (1) a device for manufacturing a metal sheet joint (2) a metal sheet joint comprising a collar.
