Definitions

  • the invention relates to a cold pilger rolling mill with a reciprocating roll stand according to the preamble of claim 1.
  • Such a cold pilger rolling mill is known from US-A 3,030,835.
  • Drive the two divided transmission parts via a common drive train, the so is designed so that the cranks rotate in the same direction of rotation.
  • the back and forth movement of the mill stand of conventional cold pilger rolling mills is carried out by different crank drive designs.
  • the large moving masses of inertia Roll stands with the rolls generate very large inertia forces, which are countermeasures Make it necessary to reduce vibration emissions.
  • the countermeasures are limited to attaching counterweights to the Crank of the crank mechanism, which, however, only cause poor mass balance and are not suitable for preventing vibration emission.
  • crank mechanism Cold pilger rolling mill to simplify that this from three there are shafts arranged parallel to one another and equally spaced, of which the middle shaft designed as a crankshaft over their Crank pin connected to the push rod that can be coupled to the roll stand is.
  • a main mass is offset eccentrically on the crank, while on the other two shafts there are additional masses to balance the total inertia of the roll stand.
  • the invention proposes that the drive train be off Engine, clutch and bevel gear and the cranks of the two gear parts in rotate in opposite directions to each other.
  • a crank operation which consists of two on the right and one on the left of the rolling center arranged sub-transmissions, the axes of rotation of the shafts of Sub-transmission are horizontal, with the exception of the drive shaft preferably in one common level.
  • the division into two gear parts enables free passage for the rolled pipe also large dimensions, the drives below or also are to be arranged above the roller level. This will only make flat foundations required.
  • crank drive arrangement allows the use of non-offset Push cranks as a roll stand drive, which was the case with previous drives, for example of the type SEA was not possible because the pipe produced in the cold crawl process via the crankshaft had to be led away.
  • the drive of the cold pilger rolling mill one arranged below the rolling plane Drive motor with drive shaft parallel to the rolling axis has the interposition of a clutch with a transfer case is connected, the two sides of which are perpendicular to the Rolling axis and horizontally running output shaft halves the drive torque introduce into the transmission parts. That way it has to generated pipe just passed over the underlying drive while the crank drives are half on both sides of the tube are arranged.
  • the centrifugal weights on the cranks of the gear parts are equal to the centrifugal forces of the rotating masses of the crank mechanism and push rod.
  • An additional centrifugal weight component on each crank and this component same flyweights on rotating in opposite directions with the speed of the cranks Intermediate shafts allow the complete compensation of the first order oscillating inertia force component of the roll stand and Push rod.
  • Another proposal of the invention is to compensate for oscillating Second order inertia forces are provided on the two drive shafts eccentrically arranged on both sides of the vertical plane to provide vertical rotating masses. These are double Crank speed and driven in opposite directions of rotation.
  • the additional flyweights of each gear part can be after another Proposed the invention also divided into two parallel waves be on both sides of the split crank mechanism of each gear part are arranged synchronized via spur gears.
  • crank mechanism solves the task the following effects to compensate for the mass effects:
  • the centrifugal weights on the cranks initially equal the centrifugal forces of the rotating masses of crank mechanism and push rod.
  • An additional centrifugal weight component on each crank and this component same flyweights on rotating in opposite directions with the speed of the crank Intermediate shafts allow the oscillating to be completely balanced First order inertia force component of the roll stand and push rod.
  • the centrifugal weights on the intermediate shafts can also be reduced to two Waves be divided.
  • the special arrangement of the gear parts prevents the formation of Moments of inertia due to the flyweights, because they are in the crank drive parts Compensate remaining moments of inertia.
  • cranks The opposite movement of the cranks causes the mass moments compensate the push rods.
  • FIG 1 1 is the reciprocating mill stand, in which the cold pilger roller pair 2 is included.
  • a push rod 4 is pivotally arranged, the opposite side at 5 on the crank pin 6 each a crank 7 is mounted, which in turn at 8 and 9 on the housing, not shown is stored.
  • Level two mirror-image gear parts to provide both include the crank 7 as well as the other drive parts.
  • a flyweight 11 which is the sum of both Flyweights 11 of both gear parts is so large that all rotating and oscillating first order inertial forces can be compensated.
  • the drivetrain consists of, as the lower half of the drawing of Figure 1 shows the motor 12, the clutch 13 and the bevel gear 14, which the Driving torque on the two half-waves 15a aligned with one another and 15b distributed perpendicular to the drive train and horizontally.
  • Each of the half-waves 15a, 15b carries a flywheel in shape a flywheel 16 for smoothing the speed curve of the crankshaft.
  • the half-waves 15a and 15b are mounted at 17 and each enter Spur gear 18, which in the exemplary embodiment has a 4: 1 ratio translated spur gear 19 on the crank mechanism 7 and this rotates transferred.
  • the flywheels 16 and the flyweights 11 run in the direction of the arrow with synchronized speeds and enable them Way the compensation.
  • crank drive arrangement shown in Figure 2 still allows one better balance by additional flyweights 20, which together with the centrifugal forces of the centrifugal weights 11 on the two cranks 7 rotating masses of crank and push rod as well as the oscillating First order inertia force component of the roll stand and push rod compensate.
  • the additional flyweights 20 are on shafts 21 arranged parallel to the axis of rotation of the cranks 7 in the same horizontal plane and at the same time a spur gear 22 wear on the one hand with the spur gears 18 of the drive half-shafts 15a and 15 b and on the other hand comb with the spur gears 19 on the cranks 7 and transfer the drive torque with the appropriate gear ratio.
  • flywheels 16 eccentrically arranged such that they with the speed doubled compared to the crank drive speed, the oscillating Compensate for second order inertia forces. Similar components are identified in the same way in FIG.
  • Figure 3 shows a mechanism that also with the same direction of rotation of the two cranks 7 a perfect balance of the mass forces and first order inertia moments, but then none Equalization of the mass moments of the push rods.
  • the one shown here Arrangement of the crank mechanism according to the invention are the additional ones Centrifugal weights 20a and 20b divided into two shafts 21a and 21b, which are arranged on both sides and parallel to the axis of rotation of the cranks 7. Both flyweights 20a and 20b run in the opposite direction to the crank rotation Direction around, the drive torque via the spur gears 18, 22a, 19 and 22b is distributed.
