Abstract

1399377 Extruding; forging LANGENSTEIN & SCHEMANN AG 30 June 1972 [30 June 1971] 30701/72 Addition to 1352375 Headings B3P and B3H [Also in Division B5] A press comprises a ram 4 driven by a wedge 5 sliding on one end thereof, an impact mechanism acting on the wedge in the direction of movement of the wedge and including a rotatable spindle 8 and flywheel(s) 17, 18, and an hydraulic press mechanism 11, 12 for applying a substantial force to the wedge in its direction of movement whereby the press may be used to carry out a flow pressing operation. The spindle is either axially fixed in the wedge or in the press frame, and the flywheels 17 and 18 are spring pressed against a flange 16 secured to the spindle and are rotated thereby. Alternatively the weights may be driven by an electric motor (21, Fig. 4, not shown) and are detachably coupled to the spindle. During an impact operation the spindle may be driven by an electric motor or by a piston 13 movable inside the piston 12. During flow pressing both pistons act on the wedge. In Fig. 3 (not shown) there are a pair of cylinders having a common piston-rod connected to the wedge, the smaller cylinder alone being operative during impact operation. The ram is retracted by a pair of hydraulic cylinders 7. The ram may carry an extrusion moulding punch and a stamping or forging punch side by side. Beneath the ram there may be a sliding table carrying two pairs of dies arranged so that while one pair is being punched the other pair can be loaded and unloaded by pinchers. Ejector pins are situated beneath the table in alignment with the ram.
