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 the quick locking of the tool on the movable bar of a forging press and for which hammer head rods are used for locking, is known (German utility model No. 7 143 873).
  • 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 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 out through slotted holes in the tool.
  • the object of the present invention is therefore a device for clamping the upper saddle for heavier tools to create, which also allows a rotation of the tool by 90 °, and which is simple and robust in construction and handling and works practically semi-automatically from the control panel without manual work.
  • 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 disposed below the stringer protective plate reuzschlitzring with its hammer head protruding hammer-head rod and arranged on the base of the upper saddle K, wherein a slot provided axially continuously as input and Ausfahrschlitz for the hammer head and a 90 ° befind Anlagen to downwardly open slot as a driver slot with the Hammer head of 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.
  • both processes can be controlled from the control panel without any manual activities.
  • the combination of the hammer head with the Phillips ring which is attached above at the foot of the upper saddle, for the purpose of coupling the. Both parts, whereby a lifting of the upper saddle from the lower saddle and at the same time a rotation by means of the hammer head rod is made possible, can be done remotely via hydraulic elements. A rotation is of course only possible if the hammer head rods of the upper saddle clamping device are unlocked in advance by the tool and retracted in the direction of the movable spar.
  • the hammer head and the Phillips ring represent simple parts that are not very susceptible to rough forging and whose maintenance is low.
  • 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 be pressed against the spring pressure with its lower part from a compression plate mounted on the protective plate into the protective plate and does not hinder its 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 of which then move into the inputs and Removal slots 8 of the upper saddle foot 4 a stand.
  • a two-part hammer head rod 9 is mounted with its upper part 9 a on the spar 1 (FIG. 2).
  • the lower part 9 b can be displaced into one another counter to the pressure of a compression spring 10 in a bore 11 of the upper part 9 a and is also designed to be non-rotatable relative to one another by means of a spring wedge 12.
  • the upper part 9 a of the hammer head rod 9 is provided with a lever 13, to which a rotary actuator 1 on the spar 1 Articulated hydraulic cylinder 14 attacks (Fig. 1).
  • the lever 13 is fastened to a bushing 15, which is connected in a rotationally fixed manner to the upper part 9 a via a wedge 16 and is fastened to the spar 1 by means of a coupling ring 17.
  • the upper part 9 a is supported in a bearing bush 18 which is embedded in a bore in the spar 1.
  • the lower part 9 b of the hammer head rod 9 is offset down and stored in a lower two-part bearing bush 18 a, which is embedded in a protective plate 19 arranged under the spar 1.
  • the hammer head 20 of the hammer head rod 9 protrudes through a Phillips ring 21 into a circular recess 22 in the upper saddle foot 4 a.
  • This recess 22 has a depth that corresponds at least to the height of the hammer head 20.
  • the Phillips ring 21 (FIGS. 4 and 5) is fastened to the top of the upper saddle foot 4 a by means of screws 23 and is provided with a continuous slot 24 for the installation and removal of the hammer head 20 as well as a non-continuous coupling arranged at 90 ° to it. or 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 holes 27 in the protective plate 19 by two centering bolts 26 inserted into the upper saddle foot 4 a to 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 3 a in the direction of slots 8 in the upper saddle foot 4 a.
  • the upper saddle 4 lies on a lower saddle 29 (FIGS. 2 and 3) under the movable spar 1.
  • the movable spar 1 moves downwards until the protective plate 19 rests on the upper saddle foot 4 a.
  • the hammer head rods 3 are pressed 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 4 a.
  • 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 raised onto the upper saddle foot 4 a (FIG. 2).
  • the hammer head 20 of the hammer head rod 9 of the rotating device is guided through the continuous slot 24 into the recess 22 in the upper saddle foot 4 a 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.
  • 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 by 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.
