Definitions

  • the invention relates to a drive for a cold pilger rolling mill with mass and mo ent balance according to the preamble of claim 1.
  • Such a cold pilger rolling mill is known from DE-AS-27 40 729, the crank mechanism being arranged laterally offset from the rolling mill.
  • the crank is connected via a crankshaft crank to the balancing mass for torque compensation arranged above the crank mechanism. This is arranged 90 ° out of phase with the crank, and the reciprocating movement is made possible by parallel guides.
  • the rolling mill itself is coupled via a long l / connecting rod, which is supported on the crankshaft crank on one side.
  • the object of the invention is to develop a compact, cost-effective and as little stressed design for the drive from the existing knowledge of the mass and moment compensation of the double slide.
  • the overall vertical design makes it possible for the rolling stand to engage on one side and thus be guided over the entire gear unit. This eliminates the need for a connecting rod that connects the roll stand to the gear unit.
  • the paddock engages the slide directly below the roll stand.
  • the mass required for torque compensation is provided by the coupling itself.
  • the center of gravity of the coupling was placed beyond point D of the positive guidance.
  • the total mass of the coupling is reduced to point D, which in turn keeps the dimensions of the coupling small (flat
  • the coupling rotates with -f and contributes with its mass moment of inertia ®K to an improved uniformity of the overall system. Due to the design and arrangement of the coupling, the focal planes of torque compensation, mass compensation and the roll stand are brought together as closely as possible. This results in a compact design and a relatively low load within the gear unit.
  • the slide guide and positive guide lie approximately in the same plane. This was made possible by an interruption in the forced operation.
  • the positive guidance is only required in the end positions in order to maintain the direction of rotation of the coupling and crank.
  • the embodiment according to claim 3 represents a modified embodiment, with a planetary crank gear (PKG).
  • the structure of the PKG is almost identical to the previously described first version of a double slide mechanism (DG).
  • the difference to the DG is that there is no forced guidance.
  • This is replaced by a planetary gear, which consists of a pinion and an internally toothed gear.
  • the pinion is firmly connected to the crank pin and rolls on the external internal teeth due to the rotating movement of the crank.
  • the superposition of the rotational movement of the pinion and crank results in an exactly opposite one
  • the focal planes of mass and moment balancing and of the rolling mill are relatively short distances apart. This reduces the loads on the bearings and journals.
  • Figure la, b schematically shows a section of a top view of the first embodiment of the drive according to the invention (double slide transmission),
  • FIG. 2 shows a cross section through a structural design of this first drive, FIG. 3a, b the movement of the coupling and crank in two positions,
  • Figure 4a, b schematically shows a section and a plan view of a second embodiment of the drive according to the invention (planetary crank gear) and
  • FIG. 5 shows a cross section through a design of this second drive.
  • the rolling stand (WG) can be moved in a slide guide (Seh).
  • the roll stand is connected to the coupling (KO), which is arranged below the roll stand, and runs about a vertical axis via a pin.
  • the coupling (KO) has a cam roller (1), by means of which the coupling (KO) is guided in positive guides (2).
  • these positive guides (2) are only provided in the area of the end positions of the cam roller (1) or the Koppe] (KO).
  • the coupling (KO) is connected to the crank (KU) via the crank pin (3).
  • Figure lb shows the conditions of crank (KU), coupling (KO) and
  • FIG. 3a and b which show the coupling (KO) and the crank (KU) in different positions to each other, also serve to better understand the sequence of movements.
  • the crank (KU) is connected to the drive (8) (not shown) via a corresponding toothing (5-7).
  • the second embodiment shown in FIGS. 4a, b and 5 differs from the first embodiment in that a planetary crank arrangement is provided instead of the positive guides.
  • the point B on the roll stand is shifted from the kinematic consideration for the same, opposite rotary movements taking into account the geometry present in FIG. 4b.

Abstract

Dans un mécanisme d'entraînement pour laminoirs à pas de pélerin froid avec équilibrage des masses et des couples, la manivelle entraînée est reliée par une bielle à la cage du laminoir. Afin d'obtenir un entraînement ayant une construction compacte, économique et soumise à aussi peu de contraintes que possible, la cage (WG) du laminoir est agencée directement au-dessus de la commande à manivelle (KU) et la bielle (KO) est montée directement sur le tourillon (3) de la manivelle. L'équilibrage des couples est assuré par la masse toute entière de la bielle (KO) et l'équilibrage des masses est assuré par la masse toute entière de la minivelle (KU).
