摘要： The invention relates to a method for extracting a die (4) from a hollow object (11) having several grooves (16, 17) arranged opposite one another on the surface of the inner sheath whereby the longitudinal axes thereof extend crosswise relative to the corresponding longitudinal central planes (i.e. cross-grooves), whereby said die (4) is part of a tool (10) having a matrix (1) for forming the hollow object (11) and several other die segments (9a, 9b) arranged opposite one another relative to the central axis (2) thereof. Each of said die segments has an outer ridge (21a, 21b); in order to form the hollow object, said die segments (9a, 9b) are expanded into a working position, whereby the ridges (21a, 21b) are fitted into corresponding grooves (16, 17), and extracted after the hollow object (11) has been formed. In order to facilitate extraction, all die segments (9a, 9b) are extracted by contraction movements (9d) perpendicular to the central axis (2) and a relative axial movement (9c) between the die segments (9a, 9b).

摘要： The subject matter of the invention is a method of manufacturing a shift gearwheel (1) with coaxially disposed and axially projecting shift teeth (5), which have an axial undercut. To said end, a shift gearwheel blank (1) having preformed shift teeth (5) and a forming tool (16) having corresponding tooth recesses (18) are brought into engagement and set in gyratory motion relative to one another. Further described are a device for effecting the method and a shift gearwheel (1), which may be manufactured by the method. The latter is notable for the fact that the flanks (23, 24) of the shift teeth (5) upon completion of the manufacturing method are concave so as to produce an undercut.

摘要： The invention relates to a method of manufacturing the outer part of a constant velocity joint, the outer part having in the finished condition a hollow chamber with a cylinder-shaped inner wall, in which there are provided ball raceways (1c) which run obliquely of the cylinder axis and are inclined with respect to one another. First, a wobble press die (4) is axially introduced into a goblet-shaped preliminary workpiece (1a) for the outer part having a conically developing inner and outer wall and pre-formed ball raceways (1c) in the inner wall. The preliminary workpiece (1a) is pressed (drawing process) by means of the wobble press die (4), sitting on the floor of the hollow chamber, through an opening in an outer die (2), so that a drawing process is carried out in which the preliminary workpiece (1a) is so cold formed that the inner wall of the hollow chamber is given a cylindrical shape. Thereafter the outer die (2) and the wobble press die (4), having a truncated cone-shaped outer contour, and having elevations (4a) on its outer side corresponding to the ball raceways (1c) and having a lesser diameter than the cylindrical hollow chamber of the drawn preliminary workpiece (1a), are set into a wobbling circular movement relative to one another such that the elevations (4a) of the wobble press die (4) move over the pre-formed ball raceways (1c) on the inner wall of the hollow chamber in a pressing and material shaping manner. Thereafter the wobble press die (4) is axially drawn out of the preliminary workpiece (1a) and finally, the finished joint outer part is ejected from the outer die (2).
