  • Publication number: 20120131977
    Abstract: A forming machine comprises a shearing device for shearing off a section of a bar stock, a forming station for forming the sheared off bar stock section and a transport device for the bar stock. The shearing device has two shearing blades, of which one is movable transverse to the longitudinal extension of the bar stock. The shearing blades each have an assembly block and a shearing insert attached to this. For one of the shearing blades, the shearing insert is made of a heat-resistant, break-proof and thermal shock-resistant hard material and essentially has the form of a cylindrical half-shell. This shearing insert is arranged in a reception recess of the assembly block, which is adapted in shape, and is releasably clamped to the assembly block by means of screwed clamping blocks.

  • Patent number: 6286350
    Abstract: A hot-forming machine for the hot-pressing of workpieces comprises a die (5), an associated extendable and retractable ejector (7) and a forwardly and backwardly movable press ram (1). The ejector (7) is connected to a control piston (8) arranged displaceably in a pressure chamber (28). Liquid can flow out of the pressure chamber (28) via a liquid outlet bore (24) and a liquid discharge line (23). By means of a throttle (25) arranged in the liquid discharge line (23) the outflow of liquid and therefore the repulsion of the extended ejector (7) by the forwardly moving press ram (1) are delayed in such a way that a workpiece (4) arranged between ejector (7) and press ram (1) is pre-upset and descaled outside the die (5).

  • Patent number: 4791803
    Abstract: In a multi-stage forming machine, a die-change device, for male dies in a male-die block has a mounting plate for receiving a clamping face of the male-die block on one side. Bayonet fasteners on hollow pistons in the mounting plate then engage the male dies, and a pressure medium then moves the hollow pistons to move the male dies against thrust pieces displacably in the hollow pistons and the thrust pieces against an adjusting wedge on the opposite side of the mounting plate.

  • Patent number: 4488420
    Abstract: A device for feeding material in the form of a coil of wire from a fixture for receiving and rotating said coil of wire through a straightening apparatus and a heating station to a hot and semi-cold metal-working machine in an intermittent manner. The device includes a cold feeding fixture with one or more pair of rollers which act on the cold wire to pull the wire from the coil and through the straightening apparatus and a hot feeding fixture downstream of the heating station with at least one pair of feed rollers which act on the hot wire and urge the hot wire against a stop of the metal-working machine. The device also includes adjustable link means for driving both feeding fixtures in formulant synchronism with the metal-working machine.

  • Patent number: 4227390
    Abstract: The present invention relates to transfer mechanism for multiple punch presses with two co-operating pairs of conveyor tongs which are fixed to a carrier element. The carrier element is movably mounted in a housing and driven to-and-fro to the operating rhythm of the punch press. The carrier element includes a bore effective to direct a lubricating fluid therethrough. Lubricating lines supply lubricating fluid to the bore at a desired fluid pressure. The bore has an outlet opening contiguous to the structure which incorporates the conveyor tongs. In the event that the conveyor tongs break away from the carrier element, the outlet opening of the bore is uncovered and the fluid pressure drops. The power supply to the press and the lubricating fluid supply are stopped in response to such a pressure drop.
