Definitions

  • the first one of the above two requirements stems from the necessity of, on the one hand protecting the tool against a considerable temperature rise and, on the other, preventing such a great loss of heat from the workpiece that its capacity to be subjected to the deformation in question is reduced to an unacceptable level.
  • the prevailing circumstances call for a great number of strokes during a short time period.
  • 390,173 is that it comprises a power-driven, large mass, annular flywheel supported at its periphery only and provided at the inner side of the wheel rim with excenters, cam curves or similar guiding means which, over forcemultiplying means, actuate the movable tool.
  • the force-multiplying means in such a machine comprises wedges, which are displaceable in the radial direction of the fly-wheel and arranged to generate a tool-actuating force directed parallel to the rotational axis of the wheel.
  • FIG. 1 is a part-sectional, vertical view of the machine
  • FIG. 2 is a vertical section through the central portion of the machine, taken in a sectional plane rotated by 90 relative to the corresponding plane in FIG. 1.
  • the machine shown on the drawing has a base 1 secured in an immersed position in a concrete floor.
  • the base supports the machine frame proper which comprises a lower yoke 2, two columns 3 and 4, and an upper yoke 5.
  • This frame is in its entirety surrounded by a reinforcing frame 6 comprising wires or tapes 7 biased under tension. The location of those biasing means is apparent from the broken away portion at the top of FIG. 1.
  • the machine is intended by a pressing operation to deform a workpiece (not shown in the drawing) positioned between a stationary and a mobile tool.
  • the stationary tool can be constituted either by the bottom surface of yoke 5 or, which is generally the case, by a die or the like secured thereto.
  • the mobile tool in this case comprises a press piston 8.
  • the latter is guided by a heavy ring 9 mounted at the top of a generally parallel epipedic box 10.
  • two wedges 32 and 33 which over slide shoes 24, 26 and coupling means 31 may be forced radially inwards with respect to the longitudinal axis of piston 8 under the influence of guide rails 22 and 23, arranged in the inner wall of an annular fly-wheel 21.
  • a gear ring 30 for cooperation with drive means, including pinions or tooth-wheels.
  • drive means including pinions or tooth-wheels.
  • Those components can be conventional and have accordingly not been shown on the drawing.
  • means 31 can be displaced into and out from their active positions, in which latter case wedges 32, 33 are disengaged and not actuated upon the fly-wheel irrespectively of whether its rotational movement is interrupted or not.
  • the radially outwards directed movement of the wedges is effected by the gravity force exerted by the heavy piston 8 resting on top of them. It is generally suitable to arrange special stop means limiting said outward movement of the wedges, as this function cannot be performed by means 31 when they are in their disengaged position.
  • a device as above described can be combined with one or more devices arranged according to the teaching of said application Ser. No. 390,173.
  • the machine may comprise wedges which are hydraulically controlled, the related hydraulic cylinders acting between the wedges and a stationary annular frame suitably provided with a tension-biased winding absorbing the reactional forces.
  • Such a mechanism can also be used for the purpose of adjusting the free working space of the press to match it to workpieces of different heights. Accordingly, in such a case the mechanism is passive during the working operation proper of the press.
  • a machine for treating workpieces at elevated pressures comprising:
  • At least one tool (8) which is movable in relation to said stationary tool
  • force-multiplying means comprising at least two wedges (32, 33) having mutually cooperative inclined surfaces coupling said control means to said movable tool and arranged such that said control means imparts a radial movement to said wedges relative to said fly-wheel to generate a force parallel to the rotational axis of the fly-wheel (21) and driving said movable tool (8).
  • control means (22, 23) of said fly-wheel (21) includes internal cam curve control means (22, 23) coupled to and actuating said wedges (32, 33) of said forcemultiplying means.
  • cam curve means (22, 23) are circular.
  • said force-multiplying means includes slide shoes (26, 24) coupling said cam curve means (22, 23) to said wedges (32, 33).
  • said force-multiplying means further includes coupling means (31) for selectively engaging and disengaging said wedges (32, 33) with said cam curve means 22, 23
  • said control means of said fly-wheel (21) includes internal cam curves (22, 23) each of which is circular but excentrically located both in relation to the rotational axis of the fly-wheel (21) and to the centers of the other cam curves so that, in the active positions of the wedges, the fly-wheel is subjected to symmetric loads.
