The method includes providing a flat blank to a transfer press having a plurality of stations and performing a plurality of pressing operations, in which the flat blank is formed into a cup shape, rough splines are formed on the cup shape, and the rough splines are further pressed to define smooth splines. The component includes a continuous smooth inner diameter defined by a punch of the transfer press and a plurality of smooth splines defined by a die of the transfer press. The minor diameter of the splines is not machined to form the splines.

The invention relates to a method for producing a rod- or pipe-shaped connecting element (100, 100′) having an end face (106) from a semi-finished connecting element (102) made of metal, in particular of a drill or chisel insertion end which is secured in an axially movable manner in a chuck of a hammer drill, a semi-finished connecting element (102) is provided, characterized in that at least one radially movable forming body (206) guided in the recesses (204) of a die (202) for forming at least one longitudinal groove (122, 124) closed on both sides in the semi-finished connecting element (102) has a smaller longitudinal extension (LR) than a planned length (L) of the longitudinal groove (122, 124) and that the forming of the at least one longitudinal groove (122, 124) closed on both sides in the semi-finished connecting element (102) is performed by radially applying the at least one forming body (206) and by subsequently axially shifting the semi-finished connecting element (102) in a longitudinal die opening (214) of the die (202).

To provide a method of manufacturing a shaft for a steering device, the shaft including a spline shaft part to be coupled with an input shaft, a stopper part to be coupled with an output shaft, and an intermediate shaft part that couples the spline shaft part with the stopper part. The method includes: a step of forming a hole part recessed in an axial direction from one end of a pillar-shaped material by forging; and a step of pressing the material in which the hole part has been formed into a die to perform drawing in a radial direction on a portion of the material at which the spline shaft part and the intermediate shaft part are formed, and prolonging a length along the axial direction of the hole part at the same time by forging.

A method for shaping a hollow valve preform of a pull rod (20) includes a structuring bulb (22) which is inserted into the cavity (56) of a shaft portion (44) of a valve preform. The structuring bulb (22) has an outer diameter, and has an outer structuring, whereafter the hollow shaft portion (44) is shaped, wherein at least a portion of an inner diameter of the cavity (56) is reduced below an outer diameter of the structuring bulb (22). The structuring bulb (22) is then pulled out through the shaped shaft portion (44), wherein the outer structuring is at least partially pressed into the surface of the cavity (56).

The invention relates to a method for producing a gland or a gland blank (3), the method comprising a step of producing a blank (3) having a cylindrical shaft (5) formed on a screw head (4), and a blind hole (7) being formed in the blank (3) from an upper side (11) of the screw head (4) facing away from the shaft (5) in a, in particular further, method step, the blind hole (7) extending toward the shaft (5) and forming at least one first section (13), in particular having a polygonal cross section (Q1), preferably for receiving a screw tool. The blind hole (7) is deepened, thus forming at least one second section (14), which borders the first section (13), in a subsequent method step, the second section (14) forming a preferably at least partially continuous cross section (Q2) which is in particular smaller in size than the first cross section (Q1), the shaft (5) being widened in sections, thus forming an undercut (15) at the crossover between the shaft (5) and the screw head (4), in particular by at least indirectly displacing material from at least the second section (14) of the blind hole (7), in the subsequent method step.

A metal sleeve including a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion.

A textured workpiece includes a body having an outer surface with at least a first surface portion. At least one of the body and the first surface portion is non-planar. A first set of barbs extends from and is integral with the first surface portion. A first set of grooves is formed in the first surface portion. Each barb of the first set barbs is associated with a respective one of the grooves of the first set of grooves. The workpiece can be used as reinforcing bar (rebar).
