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: In a wire and band processing machine, a drive system is positioned on one side of a processing plate and a fastening arrangement is provided for mounting processing units on the other side of the processing plate. The processing units are connected to the drive system through holes in the processing plate. The drive system includes at least one worm shaft extending parallel to the processing plate and a worm gear can be releasably positioned in meshed engagement with the worm shaft. The axis of the worm gear extends perpendicularly to the processing plate and to the worm shaft.

Abstract: A workpiece processing machine comprises a stationary main frame 10 with at least one main processing plane G. On the one side of this main processing plane there are arranged worm shafts 15, 16, 17 and 18 extending with their axes substantially parallel with the main processing plane G, mounted in the stationary main frame 10 and connected for drive with one another. On the other side of the main processing plane G there are provided securers for the securing of processing units 25 on the stationary main frame 10. To each worm shaft there is allocated at least one main power take-off position 15a, 16a, 17a, 18a for the drive connection of a processing unit 25 with the respective worm shaft 15, 16, 17, 18 through a worm wheel, meshing with the worm shaft, with worm wheel axis perpendicular to the main processing plane G. At least three worm shafts connected for drive are arranged along mutually adjoining sides of a polygonal line.

Abstract: In apparatus for feeding stock including a feeding slide driven for reciprocal motion within a linear path between two terminal positions by a crank mechanism, an auxiliary device is provided which periodically superimposes motion characteristics on the movement of the feeding slide caused by revolution of the crank mechanism at least in the regions of the terminal positions of the linear path of the feeding slide.

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.
