Definitions

  • the invention relates to a device and a method according to the preambles of the independent claims.
  • a similar device with an additional roller and a support member for a semi-finished flange is made of DE 10 2004 040 257 A1 known.
  • An apparatus according to the preamble of claim 1 is the EP 1 537 922 A1 refer to.
  • the translational movement and the rotational movement are generated largely independently.
  • the disadvantage here is that the linear actuator responsible for the translational movement must perform the entire Verschubarbeit alone when a pure translational motion is generated, and that the responsible for the rotational movement of the linear actuator must perform the entire twisting work alone when a pure rotational motion is generated. Therefore, the two linear actuators taken together have to be designed to be larger in size both in terms of performance and dimensions than in order to be able to operate them actually required overall performance would be necessary.
  • the invention has for its object to enable the rolling profiling of cold or hot profiles with variable cross-section of rolls and dies by means of power-poorer and space-saving drives.
  • each of the two at least existing linear actuators is at a location spaced from the axis of rotation of the mill stand on the mill stand in which the linear actuator responsible for translational motion extends along the line connecting the machine-fixed support of the linear actuator and the axis of rotation of the mill stand hinged.
  • both a pure translational movement and a pure rotational movement of the rolling stand is generated jointly by the two at least existing linear actuators.
  • shifting work and twisting work are distributed over the two linear actuators, and particularly uniformly in the case of the often required pure translational and rotational movements of the rolling mill stand. Therefore, the linear actuators can be much less powerful and more compact than those of the known bending devices.

  • the two drive motors 12 protrude beyond the base plate 2 in the X direction, and they are arranged side by side parallel to the axis of the X direction.

  • the base plate 8 or the roll stand can be subjected to any combination of rotational movements about the Y-axis and translational movements in the X-direction, ie moved in two degrees of freedom, to a semi-finished profile just worked to be provided with variable cross-section.
  • Both torques and shear forces that are to be exerted are distributed evenly on both drive motors 12, so that they can be dimensioned smaller than in conventional Verstellgerüsten. Also, the power transmission members of the drive motors 12 to the base plate 8 can be dimensioned smaller.
  • the drive motors 12 are arranged so that they are parallel and not moved. This allows a short distance between roll stands, each on an adjustment frame as in Fig. 1 are shown attached.
