  • the invention further relates to a device for edging or spike edging of rolled profiles, in particular to carry out the method according to the invention.
  • Such a known device has, for example, two roles are rotatably mounted in a frame. There is usually a role stored stationary, while the other role trained hired can be. Furthermore, the frame is together with the two roles by means of a special drive in the plane of the two roller axes can be swiveled through an angle of 45 °.
  • the adjustable role so far lifted off the fixed roll so that the stick is unimpeded can get between the two roles. As soon as the stick is between the two roles, the adjustable role lowered again so that the stick passed between the rollers is.
  • DE-OS 25 33 287 describes a device for spike edging of billet-shaped rolling stock, with two parallel to each other at a distance arranged adjusting rollers, of which an adjusting roller is stationary and the other adjusting roller is adjustable.
  • the rolling stock is passed through the pair of rollers by means of truncated cone rollers tipped over an edge, with the incoming stick the adjustable roller against the restoring force of a spring in a Pass position presses.
  • This has the disadvantage that the conveyed in rolling heat by the truncated cone rollers in the skewed edge position Rolled material deformed on opposite edges and thus is damaged.
  • DE-OS 27 42 439 describes a further device for edging or Knit edges of billets known, with against rolling stock surfaces adjustable pairs of gripping devices, for example pairs of rollers, preferably between the furnace and the first stand of a rolling mill.
  • the gripping device is attached to one end of a pivot lever, whose pivot axis lies in the longitudinal axis of the rolling stock and whose at least two pivot points via parallel linkages with two or several other links are pivotally connected, whose Swivel axes in a common plane with the longitudinal axis of the rolling stock are arranged, the parallel linkages parallel to this plane lie.
  • the disadvantage of this device is that after Swing repositioned in the roll stand must be what a lifting height adjustment and other displacement devices required.
  • Swivel levers with, for example, eight joint arrangements result in one overall complex design, with this device also Bending a stick by more than 45 ° is not feasible.
  • the present invention is based on the aforementioned prior art the task is based on a method and a device of the beginning mentioned type to improve significantly while doing the rolling to pivot a fixed point of his profile, thereby turning a repositioning or avoiding movement in the rolling mill, in addition, the rolling stock against a fixed stop defined force to clamp on one side, thereby local deformations or to prevent deflection of the rolling stock and finally the construction of the canter required for this should be special simple and consequently wear-resistant and at compact design, the use of additional rolling fittings on Make roll stand redundant. And beyond that, there should be an edging be feasible up to an edge angle of at least 135 °.
  • the roller head the between its pinch rollers guided billets during the folding process over the transport level of the roller table.
  • the roller head when folding from more than 90 ° enables an edge angle of up to 135 ° and above furthermore damage or deformation or bending of the Rolled goods avoided.
  • the method according to the invention provides that at least one pinch roller is driven in rotation by a motor and thereby the transport movement of the stick on the roller table is supported; this is done by directly flanging one Hydraulic motor, for example, to the upper pinch roller.
  • the method provides that the roller head from its base position by at least 135 ° and preferably by one with an edge of the billet coincident pivot point is pivotable.
  • the measure can be used very advantageously, that the operational flow using a control unit is carried out automatically.
  • An embodiment of the device provides that the swivel drive with two that can be connected by a joint to form a kinematic unit Hydraulic units is formed, of which the one on Frame immovably arranged with its hinge Piston rod head in a linear guide transverse to the swivel axis the roller head is guided, while the other hydraulic unit hinged on the one hand and on the other hand on the roller head and between the two articulation points.
  • Fig. 1 shows an overview of the entire device for edging or Spike edges of a stick 30.
  • the device comprises a frame 20 with a hydraulic unit 19 for moving transversely to the Billet 30 transporting roller table 29, the frame 20 a with pinch rollers 1, 2 for clamping a stick 30 and with one Swivel drive 11 equipped roller head 10.
  • the one pivot axis parallel to the longitudinal axis of the stick 30 preferably around 135 ° swiveling roller head has a fixed pinch roller 2 and a pinch roller movable to pinch the stick 30 1.
  • roller head 10 on a by means of a Hydraulic unit 26 liftable and lowerable swing arm 25 with relative to the transport level x-x of the roller table 29 variable altitude arranged.
  • This rocker 25 is on the hydraulic unit 26 opposite end in the horizontal hinge axis 28 pivotally stored.
  • An embodiment of the device essential to the invention results from the fact that in guide rollers 9 in a circular guide 8th guided roller head 10 formed by hydraulic units 12, 13 Swivel drive 11 has.
  • Such a drive is straightforward, free of wear-prone elements, with commercially available Hydraulic units 12, 13 can be created and stands out by very simple and wear-free construction.
  • the swivel drive 11 is with two by a joint 14 to one Kinematic unit connectable hydraulic units 12, 13 formed, of which the one assembly 12 on the frame 20 immobile is arranged and formed with its hinge 14 Piston rod head 15 in a linear guide 16 transverse to the pivot axis of the roller head 10 is guided, while the other hydraulic unit 13 on the one hand on the joint 14 and on the other hand on the roller head 10 articulated between these two articulation points 14, 14 ' is led.
  • the dash-dotted drawing of Fig. 1 is the position of the hydraulic units 12, 13 during a pivoting movement of the roller head 10 by 135 ° around the pivot point D.
  • FIG. 1 further shows that the frame 20 with rollers 21 horizontally along a travel rail 22 on the foundation 7 is movable and with guide rollers 23 along one with the running rail 22 at a vertical distance parallel guide rail 24th is feasible, and that a hydraulic unit 19th assigned.
  • roller head 10 also makes it possible Advantage that the pinch rollers 1, 2 interchangeable and, for example, against Profile rollers are interchangeable.
  • roller head A very compact and uncomplicated construction of the roller head further results from the fact that this is an annular Guide bar 8, with which it in one with the rocker 25th connected and guide rollers 9 supporting backdrop 6 by 135 ° is pivotally guided. With this arrangement there is still extremely simple assembly and disassembly of the roller head, e.g. in the event that the pinch rollers 1, 2 exchanged and against Profile roles are to be replaced.
  • Fig. 2 shows the arrangement of the device from a front view and shows particularly impressively the compact arrangement of the individual elements and their interaction. Because here the same elements are designated with the same reference numbers, one is unnecessary Repetition of their names.
  • a roller head 10 is each clearly Representation shown. It has an annular guide web 8 with which it is connected to the rocker 25 in a Guide rollers 9 supporting backdrop 6 is pivotally guided by 135 °.
  • This construction is uncomplicated and compact. she is further characterized by the fact that all individual parts quickly can be assembled and disassembled, so that in the event of an inspection or overhaul the work required for this with a least possible effort and manpower as well as Costs are feasible.
  • An embodiment essential to the invention is particularly noteworthy characterized in that the upper pinch roller 1 with its Drive motor 4 and the hydraulic tensioning unit 3 inclusive whose guide 5 is a closed assembly as a functional unit form with the roller head 10 by means of a pivot axis 17 limitable swivel range is articulated.
