Definitions
- the invention relates to a method for the progressive bending of a metal strip, preferably a hot strip, in particular a hot rolled steel strip, in the inlet region of a thornless band reeling device, wherein the metal strip is guided and bent by rotationally driven bending rolls.
- a bending device for the progressive bending of a metal strip in the inlet region of a thornless band reeling device with a plurality of rotationally driven bending rollers is proposed.
- hot-rolled, windable metal strip is wound up into a bundle after emerging from a rolling stand or after leaving the last rolling stand of a rolling train in a band reeling device.
- This winding process can be done either with the involvement of a reel dome or thornless.
- thornless winding of the metal strip in a band coiler coil box
- the bending device comprises two above a Band carefullyweges arranged driven bending rollers and arranged below the Band properlyweges adjustable and driven bending roller, which is located in the strip running direction of the metal strip at a distance between the two above arranged bending rollers.
- the adjustable bending roller With the adjustable bending roller the bending radius of the set to be added metal band, with changing tape thicknesses can be considered.
- the driven upper bending rollers a common drive unit with a transfer case and the lower bending roller associated with a single drive. Since the metal strip has different radii of curvature during its transport through the bending device at the respective contact lines with the bending rollers, local slip occurs between the bending roller and the metal strip, which leads to surface damage (scoring) on the metal strip.
- the object of the present invention is therefore to avoid the disadvantages of the known prior art and to propose a method and a bending device in which slippage between the metal strip and the Anbiegerollen and resulting surface damage to the metal strip are largely avoided.
- the object is achieved in that the peripheral speed of all driven bending rollers is set at the respective contact line with the metal strip surface on the surface velocity of the metal strip at the contact line.
- the tape passage path of the metal strip between the bending rollers is determined not only by the position of the bending rollers to each other, but also by feed conditions resulting from the last roll stand or Zuzhourollgang, and by drain conditions or by repercussions from the Bund Struktur, such as the current Collar diameter, significantly influenced.
- These complex relationships require an individual control of the driven bending rollers in order to be able to set optimal conditions for the respective operating state. This is ensured by adjusting the peripheral speed of each driven bending roller in the bending device to the surface speed of the metal strip at the respective contact line.
- the surface velocity of the metal strip is determined at the contact line with the bending roller in dependence on the instantaneous positions of the bending rollers involved in the bending process and state variables of the metal strip in a mathematical model and in dependence of which the peripheral speed or the rotational speed of each driven bending roller is adjusted.
- the mathematical model comprises a calculation rule for determining the strains and compressions occurring at the contact line of driven bending rollers and metal strip surface and / or the resulting radius of curvature of the metal strip and depending on the calculated values, the peripheral speed or the rotational speed of each driven bending roller is determined and set ,
- the metal strip thickness, the metal strip temperature and the quality of the metal strip are incorporated into the mathematical model as default values or as measured values.
- the inlet and outlet angle of the metal strip in or out of the bending device is of great importance. Especially the outlet angle from the Bending device is significantly influenced by the current collar diameter and changes the tape passage behavior in the bending device.
- the instantaneous drive torque or a correlating size of one or more driven bending rollers continuously measured and at a drop in the drive torque or falls below a target torque the speed of the rotary drives (drive motors) or the bending rollers or the peripheral speed of the bending rollers in the sense of optimizing the drive torque distribution is changed or regulated.
- alarm signals can be generated, which allow further manual intervention.
- each driven bending roller is connected to an independently controllable rotary drive and all rotary actuators a common Control device is assigned for setting individual peripheral speeds or speeds for each bending roller.
- control device comprises a computing unit with at least one mathematical model for determining the rotational speed or the peripheral speed of each driven bending roller relative to the respective contact line with the metal strip surface.
- the mathematical model is based on the principles of strength theory and takes into account the material behavior of the metal strip in the elastic and plastic range.
- the bending device comprises at least three driven, independently controllable bending rollers.
- the control of the bending rollers here refers exclusively to the rotary drive of the bending rollers.
- Each rotary drive a bending roller are associated with measuring devices for detecting the rotational speed of the rotary drive or the bending roller and the drive torque or a correlating size of the rotary drive, and a controller for controlling the speed of the bending roller.
- the detection of the current drive torque can be done for example by a power consumption measurement with a power consumption meter.
- At least one of the driven bending rollers is supported in bearing blocks for axially parallel displacement of the bending roller, wherein the bearing blocks are connected to an adjustment and the adjusting device comprises an actuator and a position transmitter and this actuator is operatively connected to the control device.
- the bearing blocks are assigned guides. These guides can equally be arranged on special guide blocks that do not simultaneously form the bearing blocks.
- two upper driven bending rollers are supported in bearing blocks for axially parallel displacement of the bending rollers.
- the two upper bending rollers can be positioned so that the continuous metal strip downstream impose a predetermined curvature becomes.

- the wound collar is supported during the winding process on two rotatable support rollers 10.
- the bending device 1 comprises three rotationally driven bending rollers 11, 12, 13, of which two bending rollers are arranged above and one bending roller below a band passageway 14. Thus, a three-point bend of the implemented by passing metal strip.
- Each bending roller 11, 12, 13 is associated with a rotary drive 15, 16, 17 formed by an electric motor, wherein the rotary drives can be controlled independently of one another as required.
- the rotary actuators are connected to a control device 18 common to all rotary drives via signal lines for transmitting actual values of the rotary drives to the control device and manipulated variables from the control device to the rotary drives.
- the bending rollers 11, 12, 13 are rotatably mounted in bearing blocks 19, 20, 21, which in turn are supported in a housing, not shown, of the bending device.

From the position sensor, the respective actual position of the bending roller can be transmitted to the control device 18 and manipulated variables are switched to the actuator 24. With the controlled positioning of the bending rollers 11, 12 relative to the further bending roller 13, the curvature of the metal strip can be specified at the output from the bending device as a function of various influencing variables.
- the invention is in no way limited to the positioning of the upper bending rollers 11, 12 relative to the further bending roller 13.
- the adjustment of the bending rollers relative to one another can take place more or less equally by the displacement of one or more bending rolls forming the bending device.
- the employment can take place here with different structural solutions, for example linear, as shown in Figure 1, or with a lever or a lever system.
- FIG. 2 illustrates the strip pass of the progressively curved metal strip through the bending device along the strip passage 14.
