Definitions

  • the invention relates to a method and an apparatus for extruding curved extruded profiles, wherein the extruded in a Shaped countermember of an extrusion die upstream template and then curved or bent by the action of external forces and in the press flow in Part lengths is separated.
  • the Outlet device For the removal of on a strand or a tube press or a combined extruded and extruded tube extruded profiles is the Outlet device determined depending on the production program. So are in the pressing of bars, profiles, pipes and hollow sections, the facilities for designed the straight pressing, while for the manufacture of wires, the plant for the pressing in the downstream reel must be equipped.
  • Extruding for straight extrusion is located behind the example Yuholm a non-driven roller gear. When reel program can the roller table are extended laterally to make room for the wire inflow channels to accomplish. This is followed by a powered, lowerable roller table between the driven, lowerable rollers arranged Gußplatten.
  • the invention is based on the object, a method and an apparatus of to create the type mentioned above, with which the operation of the Improve extruder, in particular a trouble-free, unhindered Extraction of continuously subsequent extruded profile lengths is possible.
  • This object is achieved by a method according to the invention in that the extruded strand in the press outlet from one supporting the strand base Edition taken and after the separation of a strand length this from the Pad is moved out of the press flow and transported away, during the removal by the condition of simultaneously maintained provision a support surface for the subsequent strand.
  • multi-functional operation of the support overlay is achieved that the strand lengths are not only isolated, so that a sufficient space for the continuously succeeding strand, but for each Following strand also immediately or unchanged a support surface is present, what for. B. in a retractable and extendable or raised and lowered support pad not guaranteed.
  • a preferred proposal of the invention provides that the support pad at least in their altitude is preset. In a production change with others Dimensions of the profile to be squeezed can then be adjusted so that the from the die or the counter-spar exiting profile with its lower edge or side at the level of the support surface pads exit. Since the extruder itself a otherwise it could happen that a different sized Extruded profile emerges without contact contact and in view of the high Temperature then kinks at a certain length.
  • the support pad is advantageously multi-axially adjustable, i. also in Auspreß therapies and across to, it can be depending on the straight produced radius of curvature of the profile either closer or farther away from Position the machine unit, which always with changing profiles effective support zone is achieved.
  • the extruded strand supporting, raising and lowering table is divided into functional fields, of which the adjoining the machine-side, front functional field, rear Functional field is temporarily pivoted in a position inclined to the foundation position.
  • the front function field always remains in its position, takes over in the The main thing is the support of the profile and stands, because stationary as always, also for the subsequent extruded profiles available while that down swing-away rear functional field for the removal of the separated Profile length ensures.
  • the rear function panel is lowered so that this Part length of the support pad can slip down. There it can e.g. of a Handling robot to be taken and transferred to the drainage roller table. Until the Swinging the rear functional field into its supporting position becomes the subsequent strand profile supported solely by the front functional field.
  • a preferred embodiment of the invention provides that the table surface of front functional field is equipped with rollers and the table surface of the rear functional field is executed with graphite plates. Both measures favor the desired low-friction, always gentle for the extruded profile Support and removal support.
  • the invention is a limited, the front Function field subsequent transition area of the rear function field with Roles stocked.
  • Extruded profile lengths support these roles by passing the extruded profile onto the rear functional field.
  • the support pad can be in a simple manner bring in the most favorable position for each pressing program.
  • the support table is according to the invention at least on one side of the outlet roller table intended.
  • the one-sided arrangement of the support table is sufficient if Extruded profiles are produced with a curvature only in this direction should. However, if extruded profiles with alternating curvatures are produced, i.e. with a radius of curvature to the right or left, referenced respectively to the straight Auspreß therapies, there are such support tables on both sides of the Outlet roller table.
  • the invention proposes that both support tables to a Assembly are summarized and as an integral part of a piece of the Auslaufrollganges have.
  • To the transverse or longitudinal method of the tables is here only one adjusting means required for each direction of movement.
  • this double table assembly then positioned so that the roller table section in alignment with the rest Roller table rollers complete the outlet roller table.
  • An extrusion press 1 shown in FIG. 1 is a block 2 to be pressed by means a charging device 3 supplied. This through a shaping die extruded rod profile emerges from the counter-spar 4 and arrives at Straight presses on a arranged in the press outlet 5 outlet roller table. 6
  • a support pad or a support table 10 is arranged at the curvature direction of the extruded profiles 7a, 7b corresponding side next to the outlet roller table 6, a support pad or a support table 10 is arranged.
  • This is divided into function fields A and B, of which the extruder adjacent, machine-near functional field A is equipped with rollers 11 (see Fig .. 2), some of which are powered.
  • the functional field A is the function field B pivoted pivoted. This can be by means of a bottom and side the functional field attacking adjusting cylinder in the dash-dotted lines tilted marked tilt position.
  • A is the function field A subsequent, limited area of the function field B is also with rollers 12 while the remaining, much larger surface area of the Function field B is occupied by graphite plates 13.
  • the entire support table 10, whose function field A rests on post 14, is on the one hand by means not shown lifting elements in the direction of the double arrow Z (see FIG .. 2) in its altitude relative to the center of the extruder 1 adjustable and on the other hand, on a movable substructure 15, e.g. in a cross slide arrangement, in the direction of the double arrows X and Y, i. across and along the straight Auspreßraum 8 movable.
  • the support table 10 can therefore be before Bring the beginning of pressing in an optimum for the strand to be pressed strand, i. depending on its dimension, radius of curvature and part length.
  • An extruded, emerging from the counter-spar 4 curved or Rounded extruded profile 7a, 7b is in the embodiment of a robot 16 with a burner head 17 by flame cutting with the desired length separated.
  • the burner head 17 follows the continuously extruded strand with the squeezing speed and separates the strand profile length 7a and 7b from the continuously further ausspeßten strand above a water basin 18 from which the sloping molten metal harmless to the environment.
  • the cut to length Extruded profile 7a or 7b is already on the rollers 11 of the function field A.
  • the support table 10 and is of these, in particular by the action of driven rollers, so pulled on a gap or removed from the Auspreß Buffalo, that the continuously following extruded strand is not hindered.
  • the function field B in the Inclined position pivoted towards the bottom (see Fig. 2), so that the extruded profile length 7a and 7b slips down over this area.
  • a picking robot 19 can Then take the extruded profile 7a or 7b from there (see the right in Fig. 1 position of the gripper head 20) and transfer to the outlet roller table 6.
  • the functional field B is then pivoted to its horizontal starting position and stands with it Support and in particular for the removal of the extruded secondary profile for Available.
