Abstract: A stamping and bending machine comprises a drive housing with a drive housing visual wall and two drive housing face walls. From each of the drive housing face walls projects at least one housing box. Processing devices are attachable to the housing boxes. A distributor gear is provided within the drive housing. Each of the housing boxes accommodates a housing box shaft drivingly connected with a distributor gear and with the processing devices.

Abstract: A crank drive for the material feeder of a machine tool is constructed so that the position of the crank pin along a line of action thereof, viewed in a position/time curve of the crank pin, is a modified sine curve, which curve is modified in that the peaks of the sine curve are flattened. To achieve this, the crank pin is adjustable relative to a crank disc on the one hand by a basic eccentricity setting device and on the other hand by an eccentricity correcting device. The eccentricity correcting device comprises cams mounted stationarily on the bearing arrangement of the crank disc and a cam follower engaging the cams. The cam follower acts on a main slide movably guided on the crank disc. The basic eccentricity setting device is effective between the main slide and a secondary slide carrying the crank pin. The secondary slide is guided on the main slide.

Abstract: A material loading apparatus for material working machines comprises loading slide elements for stepwise conveying one of a wire and strip material guided in a main guide along a guidance direction. The loading slide elements having a controlled slide-mounted material clamping device, an oscillating drive connected to the loading slide elements and a controlled material holding device. Stopping of the material clamping device at its extreme positions along the main guide is achieved via slide abutments. A resilient transmission system is provided in the driving connection between the oscillating drive and the slide-mounted clamping device. The loading slide elements have, in connection with oscillating drive, a main slide guided in a main guide and a secondary slide provided on the main slide and capable of moving substantially parallel to the main guide.

Abstract: A series of plates are punched in a single punching operation from elongate strip material with the punched plates being successively then fed into a pack formation member with an essentially constant feed speed over the entire pack forming operation, with the pack formation member being moved in an essentially constant advancing speed through a pack forming advancing distance having a direction which is essentially perpendicular to the direction in which punched plates are fed into the formation member.

Abstract: A cage for a frusto-conical roller bearing is formed of a punched flat material strip so that an elongated bar extends along one side of the punched strip with a number of bars extending transversely outwardly from the elongated bar with the ends of these bars being free. As a result of the punching step a number of windows are formed closed on three sides but open on the fourth side opposite the elongated bar. The transversely extending bars are bent out of the plane of the elongated bar. When the punched strip is free into a ring the free ends of the transversely extending bars are located on a circle having a different diameter than the diameter into which the elongated bar is rolled. Another bar is rolled into a ring and is connected to the free ends of the transversely extending bars.

Abstract: A material working machine includes a plurality of workplates each capable of supporting one or more working units. The working units can be swung or rotated about an axis extending perpendicularly to the surface of the workplate. Each working unit mounts a tool carrier displaceable in a rectilinear manner into the path of a material across the workplates. At least two of the workplates extend angularly relative to one another and the angular position can be adjusted. One or two of the workplates form a slot adjacent the path of the material being worked and the tool carrier on a working unit mounted on a workplate not forming the slot is positioned to extend through the slot for effecting an operation on the material being worked.

Abstract: Contact beads of noble metal are welded to a substrate of less corrosion-resistant metal in an apparatus in which one electrode formed with a receptacle is moved cyclically between a welding position adjacent another, stationary electrode and a remote feeding position. A gap between the electrodes receives the substrate, and blanks of contact bead material are fed into the laterally open receptacle through a stationary guide aligned with the receptacle in the feeding position of the movable electrode in a direction transverse to the direction of electrode movement.
