Definitions

  • DE-A-27 48 033 has already proposed to replace the mechanical positions with hydraulic positions and to assign gage meter circuits to the hydraulic positions for short-term error correction.
  • a joint coupling of the two vertical roller gage meter circles with the two horizontal roller gage meter circles is already described here.
  • long-term errors cannot be corrected with the universal scaffold according to DE-A-27 48 033.
  • a coupling that is effective within certain tolerance ranges for the optimal removal of web and flange thicknesses is also not possible.
  • the invention has for its object to show a method by means of which web and flange thickness errors can be optimally compensated and to develop a device for carrying out the method.
  • the use of hydraulic adjustments enables precise, quick positioning, and it is also easy to implement overpressure protection.
  • the coupling of the gage meter circles ensures that the ratio of web length to flange length remains within the tolerance range and can be varied within this tolerance range.
  • the extent to which errors can be corrected on the web or flange should affect the flange or web via the selectable dimension of the coupling. This ensures that no secondary errors can occur. Secondary errors should be understood here that e.g. an error correction on the web with a hundred percent coupling would also cause a change in the flange setting, although the flanges may be exactly true to size. In this case, changing the flange setting would result in a secondary error.
  • the attenuators in the respective gage meter circle allow the penetration to be set, i.e. the degree of error compensation in the corresponding gage meter circle. For example, It makes perfect sense to only compensate for fifty percent of the errors, however, thereby remaining within the tolerance range of the web-flange-elongation ratio and maintaining a dimensionally accurate profile.
  • the invention is described below with reference to a drawing.
  • the drawing shows a universal scaffold 1 and a control arrangement for the universal scaffold 1 shown as a block diagram.
  • the universal stand has horizontal rollers 2 and 3 and vertical rollers 4 and 5.
  • the horizontal roller 2 and the vertical rollers 4 and 5 can be adjusted hydraulically, while the horizontal roller 3 can only be supported mechanically by means of packages of documents (not shown).
  • This embodiment was chosen to simplify the circuit diagram. Otherwise, two position control loops with corresponding synchronization, two gage meter circles, corresponding coupling circuits etc. would have to be provided for the horizontal roller 3 as well as for the horizontal roller 2.
  • a position control circuit 6, 6 ', 6' ', 6' '' is assigned to each positioning cylinder.
  • the position control circuits 6, 6 ', 6' ', 6' '' consist of a position sensor 7, 7 ', 7' ', 7' '' and a position comparator 8, 8 ', 8' ', 8 '' 'in which the measured position is compared with a position specified by a position setpoint generator 31, 31', 31 '', 31 ''' '.
  • the output variable of the position comparator 8, 8 ', 8' ', 8' ' is used to control a valve 9, 9 ', 9' ', 9' '' by means of which the hydraulic piston-cylinder units are acted upon Employment.
  • the position transducers 7 ', 7' ' are assigned a synchronization circuit 10 which compensates for differences between the determined position values in order to ensure an exact adjustment of the upper horizontal roller 2.
  • a gage meter circuit 11, 11 ', 11'',11''' is also assigned to the hydraulically adjustable rollers 2, 4, 5.
  • Each gage meter circuit 11, 11 ', 11'',11''' has a device to determine the rolling force, here an actual pressure sensor 12, 12 ', 12'',12''', an adder 13, 13 ', 13'',13'', a reference rolling force memory 14, 14 ', 14 '', 14 ''', a multiplier 15, 15', 15 '', 15 ''', a scaffold module memory 16, 16', 16 '', 16 ''', an attenuator 17, 17', 17 '', 17 ''', an adder 18, 18', 18 '', 18 ''', a reference roller position memory 19, 19', 19 '', 19 ''', a position comparator 32, 32' , 32 '', 32 ''and an adder 20, 20', 20 '', 20 '
  • the coupling circuits 21, 21 ', 21'',21'' have memory coupling circuits 22, 23, 24, 25, 26, 27, in which material-dependent, rolling technology relationships are stored, which determine the degree of coupling of the gage meters -Circles 11 to 11 '''are able to influence.
  • the effect of the gage meter circles 11 to 11 '' ' is described below.
  • the current rolling force of the corresponding roller is measured via the pressure actual value transmitter 12 to 12 '' '.
  • the signals of the pressure actual value transmitter 12 to 12' '' are added to a reference force signal from the memory 14 to 14 '' '.
  • the reference force signal can be stored in the memory by manual entry or by force measurement and storage during roll tapping.
  • a comparison signal formed from the reference position signal and the current position signal and any manually enterable correction signals are added to the output signal of the attenuator 17 to 17' ''.
  • the reference position signal can be stored in the memory 19 to 19 '' 'via direct input or via the position detection and storage during the roll tapping.
  • the output signals of the adder 18 to 18 ′′ ′′ are applied to the respective position comparator 8 to 8 ′′ ′′ via the adder 20 to 20 ′′ ′′ and here, as described above, converted into setting signals.
  • the coupling circuit 20 to 20 "" consists of a memory 28 to 28 “” and an adder 29 to 29 "".
  • the memory 28 to 28 ''' is switchable in such a way that it constantly switches the output signals from the adder 18 to 18''' to the adder 29 to 29 '''', where these output signals are subtracted from themselves, so that at the output of the Adders 29 to 29 '''' 0 'is present, and there is no mutual interference between the gage meter circles 11 to 11'''.
  • the memory 28 to 28 ''' can also be stopped so that from this point on, the current output signals of the adder 18 to 18 '''are subtracted from the stored signal.
  • Corresponding material-dependent coupling of the gage meter circuits 11 to 11 ''' will take place via the memory coupling circuits 22 to 27.
  • a measuring circuit 30 to 30 ''' is provided for long-term error detection, which detects the actual thickness of flanges and web and compares it with the target values.
  • the output signals of the measuring circuit 30 to 30 ''' are also applied to the respective position control loop and serve to correct the adjustment.
