The chill plate can also be used to preheat the can-forming die before the equipment is used if desired, since the heat transfer of the system is non-directional.

Abstract: Pilger rolling mill for working a hollow into a tube has a first roll stand mounted linearly moveable in a direction of motion. Translational motion of the roll stand causes rotational motion of the drive gear due to the cogging of the drive gear with the gear rack and, hence, also rotational motion of the roller arranged on the shaft of the drive gear and rotational motion of the other one of the two rollers in the opposite direction. Roll stand is connected with a crank drive and rotational motion of a motor drive is transformed into an oscillating translational motion of the roll stand by a connecting rod. Gear rack holder allows adjustment of the pilger rolling mill with respect to tube diameters of finished rolled tubes by arranging the first roll stand exchangeable by a second roll stand with a second dimension being different from the first dimension.

The fixed preform is pressed against contour segments of a second inner contour tool by a die of partial dies, fully forming the cage paths and ball tracks.

Abstract: A method for thickening a plastically deformable hollow body wall of a hollow body includes the steps of arranging the hollow body in an outer mold, arranging an inner supporting body inside the hollow body, applying a compressive force to the hollow body wall by means of two application members moving towards one another in an axial direction with a continuous compressing movement, and performing an axial relative movement of the application members performing the continuous compressing movement on the one hand and of the outer mold on the other hand. Due to the compressing movement of the application members, material of the hollow body wall is plasticized and flows into an expansion space of the outer mold, an axial extent of the expansion space increasing due to the axial relative movement of the application members performing the continuous compressing movement and of the outer mold.
