The thesis solves the design of tools for pressing round eyelet 10 mm diameter from steel sheet of DX51 0,5 mm thick. The ring is produced on the press LENA 25 C. Based on a literary study of shearing, expanding and neck drawing, a tool was developed that combines the hole punching of the sail and expanding of the ring end. The study of the circle edge appearance on SSM 3-E stereo microscope and the measurement of wall thickness using the ATOS Core 80 was performed. A simulation of the strain on the press was performed. The proposed tool was experimentally verified as working.
