Abstract: A metal spinning machine with at least one roller holder, the roller holder being mounted exchangeably on a tool rest system with a roller rotatably borne by it. The tool rest system permits the roller to be displaced in at least two coordinate directions relative to a workpiece to be formed by spinning. The workpiece can be mounted on a rotatable metal spinning machine spindle with a rotationally symmetrical shaping tool. The metal spinning machine is equipped with a means limiting the force which can be exerted by the roller on the workpiece.The new metal spinning machine is characterized by the factthat the roller holder (1) is made with two holder parts (2, 3) which are slidingly displaceable on one another, one of them being configured as a fixed holder part (2) which can be attached to the tool rest system (4) and the other being configured as the displaceable holding part (3) bearing the roller (10),that the one holder part (3) is made with a cylinder (20) which can be fed a pressure medium,that the other holder part (3) is made with a piston (30) which can be actuated by the pressure medium with a predeterminable force in the extending direction, andthat the roller (10) can be pushed back dynamically by an excessive force applied to it by the workpiece (30).

Abstract: A method for the manufacture of a machine part with external toothing from a circular sheet metal blank. According to this method the blank is fixed between a tool and a tail stock. Subsequently the circumferential edge of the circular sheet metal blank is bent by a first metal working roll towards the side of the tool by an angle of more than 180.degree. to form a curl. This curl is radially flattened with a second metal working roll. Subsequently the flattened curl is pressed against the tool with a gear cutting roll and shaped to form an external tooth system.

Abstract: Process and apparatus for producing a folded seam connection along a joint between cups made of sheet metal having flanges of folded seam connection and forming a workpiece, in particular a vibration damper, wherein at least one folding tool and the workpiece with the folding flanges, which are pressed on each other, are moved relative to one another. The workpiece is rotated around a rotating axis traversing the workpiece in an essentially perpendicular manner with respect to the plane of the joint. The folded seam connection is produced by rolling over the folding flanges once or several times by at least one folding roller. In the plane of the joint, the folding roller can be swung around relative to the workpiece and/or pressed against the latter. The process and the seaming machine offer the option to simply pass over interruptions of the folded seam connections by providing a correspondingly configured guide surface for the folding roller.

Abstract: In a flow-forming-machine having a rotatable spindle, a rotary drive for the spindle, and a pressure tool fitted to one of the spindle end faces, an axially movable counterpressure support for a workpiece is placed on the pressure tool, the counterpressure support being axially aligned with the spindle and having opposed sides. At least two rotatable pressure rollers are movably guided on a machine frame in a radial direction with respect to the spindle, while a pivot arm is provided on both the sides of the spindle and/or the counterpressure support. Each pivot arm is pivotal around an axis parallel to the longitudinal axis of the spindle by means of a powered drive. At least two pressure rollers are adjustably located on each pivot arm, and one of the pressure rollers is selectively positionable in an operable position and fixable at will for each pivot arm. The spindle together with the rotary drive and the counterpressure support are movable in the axial direction of the spindle relative to the machine frame and to the pressure rollers for executing a forming operation. The pivot arms are "L"-shaped when viewed in the longitudinal direction of the spindle, with the pivotal axis respectively lying at the free end of the short shank of the "L", the powered drive respectively engaging with the free end of the long shank of the "L" and the pressure rollers being arranged in the run of the long shank of the "L". The spindle and the counterpressure support are made in mirror image symmetry.

Abstract: Disclosed are a method, apparatus and tool for the manufacture of a deep-bed wheel rim from a hollow cylindrical preform. In the method the metal preform is shaped to the deep-bed rim in a single mounting on a single tool of several parts, and the constriction of the middle part of the preform to make the bed is performed with concentric rotation of tool and preform. The side portions of the preform are widened to make the bead flanges by a radial shifting of the axis of rotation of the preform together with a tool part shifting appropriately in the plane perpendicular to the axis of rotation to make the bed and the bead seat. The pressing at least during the widening takes place inwardly in a single radial direction, the direction of the axial shift corresponding to the pressing direction. The invention furthermore relates to an apparatus for the practice of the method. According to the invention, this apparatus is a pressing machine with two spindles which bear a tool in common. This tool has a part which is displaceable in a plane perpendicular to the spindles' axis of rotation.
