Definitions

  • the invention relates to a hydraulic upper saddle clamping device on the movable spar of forging presses, consisting of four hammer head rods arranged parallel to the press axis and the corner distances of the tool plate of the upper saddle, which can be tensioned by disc springs against the underside of the spar or the tool and thus lock the tool , and unlock the tool axially displaceable against the spring force by means of hydraulic cylinders and can be rotated by means of further hydraulic cylinders via rotating rods.
  • a top saddle clamping device which is used for quick locking of the tool on the movable handle of a forging press and for which hammer head rods are used for locking, is known (German utility model No. 7143873).
  • Hammer head rods are used here, which lock the tool by means of spring pressure and unlock the tool on the handlebar by pressing hydraulic cylinders against the spring pressure.
  • a special rotation of the hammer head rods takes place here simultaneously with the axial displacement for unlocking through specially designed sets. After unlocking the tool and rotating the hammer head rods by an angle of 90 °, the spar moves upwards, the hammer head rods with the hammer heads being lifted up out of the tool through slotted holes.
  • the object of the present invention is therefore to provide a device for clamping the upper saddle for heavier tools, which also enables the tool to be rotated through 90 °, and which is simple and robust in construction and handling and is practically semi-automatically remote-controlled from the control panel without manual action is working.
  • the clamping device in the movable spar is assigned a hydraulic upper saddle turning device arranged above the center of the upper saddle, consisting of a vertically arranged and mounted in the spar, rotatable by means of a hydraulic cylinder, from which a protective plate arranged under the spar with its hammer head projecting hammer head rod and a Phillips ring arranged on the foot of the upper saddle, with a slot axially continuous as an entry and exit slot for the hammer head and a slot open at 90 ° to the bottom as a driving slot with the hammer head the hammer head rod can be coupled, and that the foot of the upper saddle below the cross recess ring is provided with a circular recess corresponding to the longitudinal dimensions and the height of the hammer head.
  • the hammer head rod of the rotating device can be axially displaced in two parts against spring pressure and can be rotated relative to one another with the upper bearing of the upper part and lower bearing of the lower part.
  • the hammer head rod can counter the spring pressure with its lower part of a compression plate mounted on the protective plate in the protective plate are pressed back and does not hinder their assembly. Due to the lower bearing of the part with the hammer head, the two-part hammer head rod can absorb the entire weight of the upper saddle during the turning process of the upper saddle by 90 °.
  • rotary drives 2 for rotating hammer head rods 3 for locking the upper saddle 4 are provided on the movable spar 1 of a forging press, not shown.
  • the clamping position of the upper saddle 4 is shown in FIG. 1.
  • a hydraulic cylinder 5 which is articulated on the spar 1, rotates the hammer head rods 3 by 90 ° via levers 6 and rotary rods 7, the hammer heads 3 a then in the installation and removal slots 8 of the upper saddle foot 4a.
  • a two-part hammer head rod 9 is mounted with its upper part 9a on the spar 1 (FIG. 2).
  • the lower part 9b can be pushed against one another against the pressure of a compression spring 10 in a bore 11 of the upper part 9a and can also be designed to be non-rotatable relative to one another by means of a spring wedge 12.
  • the upper part 9a of the hammer head rod 9 is provided with a lever 13, to which a hydraulic cylinder 14 articulated on the spar 1 acts as a rotary drive (FIG. 1).
  • the lever 13 is fastened to a bush 15, which is connected in a rotationally fixed manner to the upper part 9a by means of a wedge 16 and is fastened to the spar 1 by means of a coupling ring 17.
  • the upper part 9a is supported in a bearing bush 18, which is embedded in a bore in the spar 1.
  • the lower part 9b of the hammer head rod 9 is offset downward and supported in a lower two-part bearing bush 18a, which is embedded in a protective plate 19 arranged under the spar 1.
  • the hammer head 20 of the hammer head rod 9 projects through a cross-slot ring 21 into a circular recess 22 in the upper saddle foot 4a.
  • This recess 22 has a depth that corresponds at least to the height of the hammer head 20.
  • the cross-slot ring 21 (FIGS. 4 and 5) is fastened to the top of the saddle foot 4a by means of screws 23 and is provided with a continuous slot 24 for the installation and removal of the hammer head 20 and a non-continuous coupling or staggered by 90 ° Driver slot 25 provided for the hammer head 20.
  • the upper saddle 4 In the locked state of the upper saddle 4 on the protective plate 19 or the movable spar 1 by means of the hammer head rods 3, the upper saddle 4 is centered in two bores 27 in the protective plate 19 by two centering bolts 26 inserted in the upper saddle foot 4a on the right and left of the press axis. Two further bores 27, not shown, are provided in the protective plate 19 at 90 ° to the former.
  • the cross slot ring 21 projects into a recess 28 in the protective plate 19 corresponding to the dimensions of the cross slot ring 21.
  • the hammer head rods 3 are rotated by means of the rotary drives 2 and hydraulic cylinders 5 with the hammer heads 3a in the direction of slots 8 in the upper saddle foot 4a.
  • the upper saddle 4 lies on a lower saddle 29 (FIGS. 2 and 3) below the movable spar 1.
  • the movable spar 1 moves downwards until the protective plate 19 rests on the upper saddle foot 4a.
  • the hammer head rods 3 are pressed down by hydraulic cylinders, not shown, acting in the axial direction of the hammer head rods 3 against the pressure of disc springs, not shown, to such an extent that they are about 30 mm below the underside of the upper saddle foot 4a.
  • the four rotary drives 2 are then rotated by 90 °, so that the hammer heads are rotated by 90 ° to the slots 8.
  • the axially acting hydraulic cylinders, not shown, are then relieved of the pressure.
  • the disc springs, not shown, now clamp the upper saddle 4 against the protective plate 19.
  • the upper saddle is removed in reverse order.
  • the upper saddle 4 To rotate the upper saddle 4, the upper saddle 4 must first be released from the clamping device, as described above.
  • the upper saddle 4 stands on the lower saddle 29, and the protective plate 19 on the spar 1 is moved onto the upper saddle foot 4a (FIG. 2).
  • the hammer head 20 of the hammer head rod 9 of the turning device is guided through the continuous slot 24 into the recess 22 in the upper saddle foot 4a and rotated by 90 ° by means of the hydraulic cylinder 14, so that the hammer head 20 is now exactly below the driver or coupling slot 25 is.
  • the spar 1 now moves upwards until the centering bolts 26 are out of the bores 27 of the protective plate 19.
  • the hammer head 20 moves into the driver or coupling slot 25 of the Phillips ring 21 (FIG. 3).
  • the hammer head rod 9 is then rotated through 90 ° by means of the hydraulic cylinder 14 articulated on the spar 1.
  • the upper saddle 4, which lies slightly on the lower saddle 29, is rotated by means of the coupling slot 25.
