Definitions

  • the invention relates to a take-off device on an extrusion press Run-out path for the support of the elongated, ejected from the extrusion press Workpiece, the face of a movable by the trigger device Gripper is graspable, with two spaced apart, parallel to the discharge path, above the runout and to the side of an imaginary vertical Longitudinal median plane of the runout rails are set and along each rail has a carriage that is mounted on each of the two Carriage is arranged an arm carrying a gripper, the arms of the two Gripper designed in one piece and are pivotable such that the gripper in the Run-out path are pivotable in and out of the run-out path.
  • Extraction devices in extrusion presses are known per se (EP-A-04 71 339; DE-A-30 40 236).
  • the rails running parallel to the run-out track, on which the wagons are attached the grippers are movably supported, vertically one above the other on the side of the discharge path, the arms that are articulated on the wagon and that carry the grippers are formed in several parts, and the sections forming an arm against each other are rotatable and pivotable or displaceable, so that the grippers that in the case of active use, drive directly above the run-out path, unhindered can go through the intended withdrawal distance.
  • the trigger device according to JP-Y-59 022 883 is also closed here name, in which the rails for the car with the grippers also above the run-out path and laterally an imaginary vertical longitudinal median plane the same are arranged.
  • the grippers are attached to arms with which they can be pivoted into the run-out path or out of the run-out path.
  • the swivel axes are parallel to the run-out path.
  • the invention aims to provide a trigger device of the type mentioned at the beginning in a structurally simple manner, if possible to design a smaller overall width, which is achieved according to the invention in that the possibly substantially L-shaped arms around horizontal and Axes pivotable at right angles to the direction of ejection of the extrusion press are.
  • the two are each expediently forming an L-shaped arm Leg rigidly connected to one another or the arm itself is designed in one piece. Welded structures are expediently provided for this.
  • the two L-shaped arms are designed identically and are the ones carrying the grippers horizontal leg of these arms to the vertical longitudinal median plane of the Outfeed path directed, so attach the gripper, which is not insignificant Strong, torsion-resistant supports are available to absorb forces.
  • the on the car legs of each arm pivoted about a horizontal axis in its swivel plane is cranked or bent, so for accommodation and favorable structural conditions for the points of attack of the adjustment mechanism created.
  • Fig. 1 shows a cross section through an outlet path 1, which is on the front side or ejection side of an extrusion press, not shown here, and on which is the elongated workpiece ejected from the extruder, hereinafter Extruded profile called 2, picks up.
  • this runway 1 is a support frame 3 arranged with an upper horizontal boom 4.
  • the runway 1 which can be up to fifty meters or more long (the runway 1 extends at right angles to the plane of the drawing in Fig. 1), there are several such boom 4 provided.
  • Rails 5 and 6 are now on these arms 4 set, both of which lie in an imaginary, common horizontal plane 23 and which in relation to the vertical longitudinal median plane 7 of the outlet track 1 are arranged symmetrically.
  • the two rails 5 and 6 run parallel to Longitudinal extension of the run-out track 1.
  • Carriages 8, 9 movably supported.
  • On each of the two carriages, which are identical Have structure is now around a horizontal axis 10 or 11, which is rectangular to the longitudinal center plane 7 of the outlet path 1, a one-piece arm 12, 13 by means of a piston-cylinder unit 14 and 15 in a vertical plane pivoted, these one-piece arms 12, 13 are rigid and convenient in themselves here L-shaped. If the arms 12, 13 are L-shaped, as shown here in the exemplary embodiment, the two legs form this L-shape a rigid unit. Like the carriages 8, 9, these are one-piece arms 12, 13 formed identically.
  • the arms 12, 13 are L-shaped, they are each horizontal legs, which carry the grippers 16, 17, to the longitudinal center plane 7 directed.
  • These grippers can be designed differently.
  • these grippers 16, 17 each consist of a U-profile piece With relatively high sidewalls.
  • On one of these sidewalls in the area of their free Axis 18 connecting ends are several, parallel to each other, free movable slats 19 pivotally mounted (at right angles to the plane of the drawing in Fig. 1).
  • Grippers of this type are the subject matter of trigger devices kind known.
  • the rails 5 and 6 and the carriages 8 and 9 lie - in relation to the drawing level - one after the other.
  • the gripper 16 has an ejected from the extrusion press, not shown Extruded profile 2 gripped at the front and pulls it to the right (arrow 20).
  • the gripper 16 is by means of the arm 12 or the piston-cylinder unit 14 lowered to the runway 1.
  • the gripper 17 and the arm 13 are raised by means of the piston-cylinder unit 15 (see FIG. 1), see above that the cars 8 and 9 can pass each other unhindered, since yes Grippers 16 and 17 are one above the other.
  • the carriage 9 drives to the extrusion press in waiting position.
  • the rails 5 and 6 which carry the grippers 16 and 17 Arms can be made in one piece and therefore very simply. They are practical in one piece, and for their actuation (lifting and lowering) is only a simple piston-cylinder unit required. Instead of piston-cylinder units 14 and 15 other lifting mechanisms can also be used.
  • the trigger device is one side of the discharge path 1 freely accessible, via which the extracted and deflected extruded profiles 2 can be removed (arrow 22).
  • the one-piece arms 12 and 13 are L-shaped designed. This L shape is not mandatory for these arms. The poor could also - seen from above - have a curved course. Rather essential is according to the invention that these arms are in one piece and between the respective Grippers and the pivot axes 10 and 11 of these arms no more There are subdivisions that can be pivoted or rotated relative to one another.
