Definitions

  • the invention relates to a cold pilger rolling mill with a reciprocating roll stand, the inertial mass of which can be compensated for by counterweights which are arranged eccentrically on the crank mechanism, which is connected to the roll stand via a push rod.
  • the present invention has for its object to provide a simple constructive and easy to assemble construction for the crank mechanism of a cold pilger rolling mill with rotating mass balancing weights, in which the space requirement is limited and expensive foundations are avoided.
  • the crank mechanism consists of three shafts arranged parallel to one another and equally spaced, of which the central shaft, which is designed as a crankshaft, is connected via its crank pin to the push rod coupling the rolling stand and on the crank thereof by 180 degrees to the articulation point the push rod eccentrically displaces one of the main masses, which balances the inertia forces of the roll stand in half Axis of rotation of the crankshaft is arranged and that two additional shafts of equal size are arranged on the other two shafts, which compensate for the other half of the inertial forces of the roll stand, the shafts being connected in a meshing manner via spur gears for synchronous rotation of the shafts and their masses such that the additional masses rotate in opposite directions to the main mass at the same speed and in the dead centers of the roll stand the sum of the main and additional masses effective there correspond to the inertial mass of the roll stand and the other masses moved with the roll stand.
  • the first order inertia forces are completely compensated for in the dead centers of the roll stand.
  • the rotating weights balance themselves. All intermediate positions are also completely balanced.
  • the arrangement of rotating masses which have twice the speed, also makes it possible to balance the mass forces of the second order.
  • the additionally provided masses are half as large as the additional masses representing a quarter of the total mass if the center of gravity distance of the additional masses from the respective axes of rotation is as large as the crank radius.
  • the shafts can be arranged both vertically and horizontally without leaving the advantages of the invention.
  • Fig. 1 denotes the rolling stand of a cold pilger rolling mill in which the individual rolls 2 are received.
  • the rolling stand 1 can be moved back and forth on the frame 3, etc.
  • the crank mechanism K is driven by a drive motor (not shown).
  • the inertial masses of the entire rolling stand are compensated for by counterweights A, B1 and B2, which are arranged eccentrically on the crank mechanism K.
  • the crank mechanism rotates around vertical axes of rotation.
  • the middle shaft 7 of the crank mechanism K is designed as a crankshaft, on the crank pin of which the push rod 5 is articulated at 6.
  • the counter mass A is offset by 180 degrees to the articulation point 6 of the push rod 5; their weight is so great that it compensates for half the inertial force of the roll stand.
  • Shafts 8 and 9 are provided parallel to shaft 7 and on both sides thereof, on which additional masses B1 and B2 of equal size are arranged, which compensate for the other half of the inertial forces of roll stand 1, the synchronous rotation of shafts 7, 8, 9 by the shafts 7, 8, 9 arranged spur gears 10, 11, 12 is guaranteed, which are intermeshed.
  • the additional masses B1, B2 run in the opposite direction to the main mass A, uz at the same speed and are arranged so that in the dead centers of the roll stand the sum of the main and additional masses A + B1 + B2 of the inertial mass of the roll stand and correspond to the remaining masses moved with the rolling stand.
  • Fig. 3 the same cold pilger rolling mill as in Figs. 1 and 2 is shown, but in the 90 degree position of the rolling stand or the crank mechanism. In this position there are no mass forces from the scaffolding, the rotating masses balance themselves.
  • Fig. 4 shows the position of the cold pilger rolling mill or the crank mechanism in the 180 degree position, here also the counterweights A, B1 and B2 completely balance the mass force, as in the position shown in Fig. 2.
  • FIG. 5 shows a top view of a cold filter rolling mill in the zero position, in which the mass forces of the second order are also compensated for.
  • two further circumferential masses C1 and C2 are provided, which are arranged on shafts 13, 14, which run parallel to shafts 7, 8, 9.
  • the additional masses C1 and C2 rotate at twice the speed as masses A, B1 and B2 and are set in motion by spur gears 15, 16, etc. such that the directions of rotation of the masses C1 and C2 are opposite.
  • a spur gear 16 driving the mass C2 meshes directly with the spur gear 12 of the additional mass B2 and a spur gear 15 driving the mass C1 via an intermediate gear 17 reversing the direction of rotation with the spur gear 10 which moves the additional mass B1.
  • FIG. 6 A particularly favorable design of the cold pilger rolling mill of the invention is shown schematically in FIG. 6.
  • the same parts are numbered the same.
  • FIG. 7 the top view of the cold pilger rolling mill according to FIG. 6, the crankshafts and balance shafts are arranged one behind the other in the rolling direction.
  • the units arranged on the crank drive K housing are easily accessible.
  • FIGS. 8 and 9 Further favorable embodiments of the invention are shown in FIGS. 8 and 9 in plan view and view, in contrast to the previously described solutions two push rods 5a, 5b being articulated on both sides of the crank mechanism K.
  • the same advantages of the invention can also be achieved here.
