Method for the non-cutting production of a hub of a transmission component possessing the hub

Device for the non-cutting production of a hub of a transmission component possessing the hub from a sheet metal blank, the sheet metal blank being formed into a cap, comprising a tool (3) carried by a main spindle (4), with a tool pin (5) and a clamping chuck (15) and a movable stop (8) which is arranged opposite the tool pin (5) and which, together with the tool pin (5) and the clamping chuck (15), fixes a cap (2), and spinning rollers (9, 10), forming rollers (11) and thickening rollers (12, 14) which successively load said cap (2).

Method for the non-cutting production of a hub of a transmission component possessing the hub from a sheet metal blank, characterized in that the sheet metal blank (21) carried by a tool (23) of a main spindle (22) and rotating relative to one or more spinning rollers (26) is reduced in thickness by spinning by means of the spinning roller (26), and the material thus obtained is deformed into a cylindrical projection (28), projecting from the sheet metal blank (21), around a tool pin (24) passing centrically through the sheet metal blank (21).

Device for the non-cutting production of a hub of a transmission component possessing the hub from a sheet metal blank, comprising a tool (23) carried by a main spindle (22), with a centric tool pin (24) and a clamping chuck (29) loading the edge region of the sheet metal blank (21) and a movable stop (25) which is arranged opposite the tool pin (24) and the outer circumference of which is larger than the outer circumference of the tool pin (24) and of which the side directed towards the sheet metal blank (21) terminates at a distance from the sheet metal blank (21) and thus forms a space by means of an abutment (34), and at least one spinning roller (26) movable parallel to the plane of the sheet metal blank (21) towards the center of the sheet metal blank (21).
