摘要： To produce a molded part with a through-hole, a rod-shaped blank is pushed through a guide into a cavity and fixed in place. The end region of the blank is compressed and reshaped into a disk. A disk core having the same cross-sectional shape as the blank is ejected out of the disk using a punch and pushed into the guide and moved back together with the unshaped part of the blank. The disk is severed from the disk core and the molded part is removed from the cavity. During the penetration step, the disk present in the cavity is subjected to an axial pressure in the disk core ejection direction and the blank is subjected to an axial counter-force opposite to the disk core ejection direction.

摘要： In order to produce a formed part furnished with a through hole, a rod material is advanced by a defined length in the direction of its lengthwise extension into a forming die through a stationary guide and then immobilised by a clamping arrangement that engages with it circumferentially. The end portion of the rod material is then axially swaged by a swaging tool and is thus shaped into a disc, the circumference of which is defined by the forming die. The disc is then penetrated axially by a dishing tool and impact extruded at the same time, the displaced material flowing between the dishing tool and the inner circumferential wall of the forming die. The formed part located in the forming die is then rotated coaxially relative to the rest of the rod material and thereby separated from the rest of the rod material by torsion shearing.
