Definitions

  • a device for fastening intermediary plates to the wall of mold includes a supporting frame formed of a pair of vertically arranged arms pivotally connected together at their upper ends and a member associated with the arms for moving them away from and toward one another. Located at the lower ends of each arm is at least one setting gun and upper and lower grippers for holding a plate prior to its attachment to'the mold by the gun.
  • Thesetting guns are arranged in pairs with the driving direction of the guns in each pair being disposed 180 apart.
  • a carrier is pivotally attached to the lower end of each of the arms.
  • the guns in each pair are each rigidly attached to adifferent one ofthe carrie rs and the upper gripper is also rigidly attached to the carrier.
  • the lower gripper is arranged for pivotal movement separate from the upper gripper and it is spring biased in the driving direction of the gun mounted on the arm with which it is associated.
  • the present invention is directed to a device including a supporting frame on which an explosive drivencharge gun is mounted for fastening intermediary plates to the wall of a mold and, more particularly, it is directed to a holder for supporting the plates prior to attaching them to the wall of the mold and to the arrangement of the setting guns in pairs for firing anchors in opposite directions for fixing the plates to the opposite walls of a mold.
  • Setting guns for fastening intermediary plates to a mold surface which are mounted on a supporting frame and have a holder for the plates positioned in front of the muzzle of the setting guns.
  • the lining of a mold with the required intermediary plates takes up considerable time because, if a known gun is used, the gun must be removed from the mold after each use and introduced again into the mold for attaching the plates positioned in the holder.
  • one or several pairs of setting guns are mounted on a supporting frame with the guns in each pair having their driving axes in substantial alignment and with the driving directions of each gun disposed 180 apart. Further, where additional pairs of guns are arranged, the driving axes of the different pairs can be arranged parallel and/or perpendicular to one another.
  • the entire plate fastening operation can be reduced to a minimum number of steps, that is, it is possible to fix at least a major part of all the required intermediary plates on the mold wall in a single operation. If certain of the pairs of guns are arranged at right angles to the other pairs, it is possible to secure the intermediary plates to the mold walls simultaneously in a single securing operation.
  • the guns are arranged in pairs movable in the direction of their driving axes.
  • a pneumatic or hydraulic working cylinder can be incorporated into the supporting device for effecting the required movement of the guns and the device can be operated by remote control from a location spaced from the mold.
  • the movement of the guns can be provided by the use of an electro-motor, an electro-magnet and the like.
  • the guns extending perpendicularly to one another are arranged in spacedplanes which extend perpendicularly to the direction of the supporting frame. With such an arrangement, all of the holding devices can be provided with the necessary intermediary plates when the supporting device is introduced into the mold.
  • the supporting device is lowered into the mold until the intermediary plat-es are in position for attachment to the mold surface and the driving directions of the guns in each pair are disposedl" apart.
  • the supporting device can be lowered further into the mold until the plates extending perpendic-' ularly to the first group of plates are located in position for attachment. Therefore, it is advantageous if each of the pairs of guns disposed in parallel relationship can be fired simultaneously.
  • pairs of guns disposed perpendicularly to one another are all located in the same plane, such as in attaching the intermediary plates to a large sized mold, it is advantageous if all of the guns can be fired at the same time.
  • the guns are tiltable in a vertical plane on the supporting frame.
  • Another feature of the invention is the arrangement of the gripping members which form the holders for the intermediary plates.
  • One of the gripping members is attached to a carrier which also supports the guns while the other gripping member is pivotally mounted on the supporting frame.
  • the gripping members are located above and below the muzzle of the setting gun and are movable toward the plane of the muzzle as the gun is arranged in the firing position. With this arrangement, it is possible to obtain a closely fitting engagement of the intermediary plates with the surface of the mold, though the mold walls are uneven. Since the gripping members arranged above and below the gun can be moved toward the muzzle of the gun until it is in the firing position, the gun muzzle can be supported on the intermediary plate so that the pressure path required for safety reasons in firing the gun can be provided.
  • FIG. 1 is a side view of a device, embodying the present invention, for fastening intermediary plates to the wall surfaces of a mold;

  • a setting gun 16, 17 is rigidly connected to the carrier so that it can be pivoted with the upper gripping member about the pivot pin 7, 8.
  • the arm 3 supports three setting guns 17 disposed in laterally spaced relationship.
  • Each of the guns 17 has a corresponding gun 16 on the opposite carrier 10 of the arm 2 forming a pair of guns arranged in the same horizontal plane with their firing directions disposed 180 apart.
  • the number of pairs of guns associated with the supporting frame 1 can be selected in accordance with the dimension of the mold 20 to which the intermediary plates 23, 24 are to be fastened.
  • the bottom gripping members arranged at the ends of the pivot pins are biased by torsion springs 21, 22 in the driving direction of the associated guns.
  • stops 30, 31 are arranged on the pivot pins 7, 8 and the bottom gripping members.
  • a working cylinder 25 such as a hydraulic or pneumatic cylinder, is pivotally connected by means of pivot bolts 26, 27 to flanges 28, 29 on the arms 2, 3.
  • the working cylinder is located intermediate the ends of the arms and can displace the arms outwardly away from and inwardly toward one another.
  • FIGS. 1 and 2 only a portion of the device is shown having several pairs of guns arranged in parallel with one another, that is the driving axes of the guns are arranged parallel to one another and in the same horizontal plane.
  • the device can be provided with two additional arms 32, 33 for supporting setting guns 34, 35 and the plate holders 36, 37 oriented at right angles tothe arrangement of the setting guns 16, 17 and plate holders 14, 15 shown in FIGS. 1 and 2, that is for securing intermediary plates to the surfaces of the mold 20 disposed perpendicularly to the sides 20a, 20b of the mold.
  • two groups of setting guns are arranged with perpendicular driving axes, as shown in FIG.
  • a head bearing 38 is used with two vertically spaced pivot bolts 5, one for each pair of arms 2, 3 and 32, 33.
  • the setting guns having their driving axes disposed perpendicular to one another, are located in vertically spaced planes as illustrated in FIG. 3.
  • the guns l6, 17 are provided with explosive cartridges and fastening members, and the intermediary plates 23, 24 are inserted into the holders 14, 15 formed by the upper gripping members 12, 13 and the lower gripping members 18, 19 so that, preferably, a three-point support is provided.
  • the device or supporting frame 1 is suspended on a remote lifting and operating mechanism 60 so that the device can be lowered into and lifted out of the mold 20.
  • the supporting frame is low ered into the mold 20 until the intermediary plates 23,
  • the working cylinders 25 are actuated over the mechanism 60 and the arms 2, 3 are moved apart for displacing the plates 23, 24 and the guns 16, 17 toward the mold walls 20a, 20b.
  • the lower gripping members l8, 19 are the first to contact the mold walls and, in reaction, move rearwardly toward the plane of the muzzles 16a, 17a of the guns.
  • the intermediary plates 23, 24 are pressed by the upper gripping members 12, 13 and the muzzles 16a. 17a of the guns against the mold walls.
