Definitions

  • the invention relates to a drive system for a rolling mill, in particular for a cold pilger rolling mill, with the features specified in the preamble of the independent claim, as by the DE 18 15 521 A1 known.
  • a disadvantage is both in this known embodiment, as well as in the version with hydraulic motors as drives according to the generic document DE 18 15 521 A1 in that, overall, a rather complicated construction of the entire drive system results, because a large number of machine elements - intermeshing via toothing - are required. This also increases the cost of the drive system and thus of the cold pilger rolling mill, which means not only the investment costs for the system itself, but also the costs for the plant foundation, for spare and wearing parts and for maintenance and repair.
  • the DE 36 13 036 C1 discloses a drive for the mill stand of a cold pilger mill using a planetary crank drive to drive and balance mass and mass moments. Although with this solution, an optimal mass balance can be done, this drive is only suitable for smaller cold pilger mills, because in larger systems, the size of such a drive system increases disproportionately and thus causes high costs.
  • crankshafts In known drive systems for cold pilger rolling mills, two-cranked, expensive crankshafts are therefore used which move the rolling stand in an oscillating manner via push rods.
  • the balancing weights on the crankshaft and on additional rotating additional shafts eliminate the mass forces caused by the rolling motion of the rolling mill.
  • the invention is therefore based on the invention to design a generic drive system in particular for a cold pilger rolling mill so that the mass forces - at least the first order - can be kept as low as possible in a simplified and thus cost-effective design.
  • the two units are preferably formed mirror-image to the center plane.
  • the electric motor is preferably designed as a low-speed, high-torque motor.
  • the crank mechanism is preferably designed as a non-limited crank.
  • the proposed drive system is preferably free of further waves with balancing weights.
  • the masses of the balance weights can be selected so that the first-order framework mass forces are at least substantially, preferably completely, compensated during operation of the drive system.
  • crank mechanisms are very simple. In particular, it does not require the special crank mechanisms which are typically used in the previously known drives for cold pilger mills. In particular, can be dispensed with doubly cranked crankshafts, which are complicated and expensive.
  • a separate balance shaft can be omitted, as is known in the art.
  • the entire system can build shorter by the proposal according to the invention.
  • the drive system makes the mechanical connection of the two crankshafts of the crank mechanisms dispensable.
  • the crank mechanisms are designed as unrestricted cranks; the push rod joint to the rolling mill thus moves on a straight line which passes through the axis of rotation of the crank.
  • Both cranks are preferably driven by separate motors.
  • the cranks have an opposite sense of rotation, which is why alone with the balancing weights on the cranks mass forces of the first order can be fully compensated.
  • An additional shaft with counterweights can be omitted assuming opposite rotation of the cranks.
  • FIG. 1 and 2 shows a drive system for a rolling mill, which does not fall below the intended scope.
  • a drive system 1 is used to drive a cold pilger rolling mill, of which a rolling stand 2 is shown, which is in the horizontal direction oscillating back and forth to perform the known cold pilger rolling process.
  • the oscillating drive of the roll stand 2 takes place with two mirror images of a vertically aligned center plane 8 (s. Fig. 2 ) arranged units, each consisting of a crank mechanism 3 'and 3 ", a crank arm 4' and 4", a balance weight 5 'and 5 "and a push rod 7' and 7" exist. These units are known as such for driving a cold pilger mill.
  • crank mechanism 3' of the one unit rotates on one side of the center plane 8, for example in a clockwise direction
  • crank mechanism 3 "of the other unit on the opposite side of the center plane 8 moves counterclockwise.
  • the rolling stand 2 is acted upon by two push rods 7 ', 7 ", which in turn are driven in opposite directions via the two crank mechanisms 3', 3" by the separate motors 6 ', 6 “. 5 “of the crank mechanisms 3 ', 3” rotate in opposite directions, so that mass forces of the first order can be completely compensated.
  • gearbox 9 ', 9 has been dispensed with between the motors 6', 6" and the crank mechanisms 3 ', 3 ", ie the drive of the crank mechanisms 3', 3” takes place directly from the drive shaft of the motors 6 ', 6 ".
  • the waiver of the reduction stage of the transmission 9 ', 9 " is favored or made possible by the use of low-speed and high-torque motors.
