Method for producing trapezoidal tooth support rings which are used on coupling members in synchronizing systems of vehicle transmissions, from prefabricated blanks or from a sheet-metal strip unwound from a coil, characterized in that in a multi-stage cutting and forming tool on prefabricated blanks that are fed along the blank-insertion direction, or on sheet-metal strips that are fed along the sheet-metal-strip-infeed direction, the following method steps are successively disposed in the direction of the method sequence: - cutting positioning openings and stress-equalization openings as internal breakouts in the round sheet-metal parts; - central-position pre-positioning conjointly with subsequent stamping on the upper side and simultaneous impressing on the lower side of an external periphery on each sheet-metal part; - central-position precision-positioning conjointly with in each case subsequent pre-embossing of the trapezoidal shape, intermediate embossing of the trapezoidal shape and of a relief pre-positioning stamping, and final embossing of the trapezoidal shape; - rotationally secured central-position precision-positioning as a result of post-processing of the positioning opening in each sheet-metal part by cutting simultaneously with the final embossing of the trapezoidal shape and the complete cutting of the ring shape, with cutting out the profile-imparting tooth shape and the internal scrap fragment of the sheet-metal part from the ring part, or the scrap-severing cut of the sheet-metal disk-holding skeleton; - rotationally secured precision-positioning of the ring as a result of cutting positioning windows in each ring part conjointly with the subsequent edge-embossing, the embossing of an encircling chamfer on each ring part, and the embossing of the contact locations, and - transport-positioning on a finished-ring transport installation directed towards a finished-ring storage, as well as separately discharging scrap from the multi-stage forming and cutting tool. - cutting positioning openings and stress-equalization openings as internal breakouts in the round sheet-metal parts; - central-position pre-positioning conjointly with subsequent stamping on the upper side and simultaneous impressing on the lower side of an external periphery on each sheet-metal part; - central-position precision-positioning conjointly with in each case subsequent pre-embossing of the trapezoidal shape, intermediate embossing of the trapezoidal shape and of a relief pre-positioning stamping, and final embossing of the trapezoidal shape; - rotationally secured central-position precision-positioning as a result of post-processing of the positioning opening in each sheet-metal part by cutting simultaneously with the final embossing of the trapezoidal shape and the complete cutting of the ring shape, with cutting out the profile-imparting tooth shape and the internal scrap fragment of the sheet-metal part from the ring part, or the scrap-severing cut of the sheet-metal disk-holding skeleton; - rotationally secured precision-positioning of the ring as a result of cutting positioning windows in each ring part conjointly with the subsequent edge-embossing, the embossing of an encircling chamfer on each ring part, and the embossing of the contact locations, and - transport-positioning on a finished-ring transport installation directed towards a finished-ring storage, as well as separately discharging scrap from the multi-stage forming and cutting tool.
