Definitions

  • ABSTRACT An apparatus for balancing inertial forces of reciprocatingly moving masses of tube cold rolling mill stand comprising an air cylinder connectedwith said stand by means of a plunger and having two vertically and two horizontally disposed journals, the longitudinal axes of which are arranged in one vertical plane.
  • This invention relates to the rolling industry, and more specifically, to devices for balancing inertial forces of reciprocatingly moving masses of a stand of the tube cold rolling mill.
  • said air cylinder is additionally provided with two journals vertically disposed along the cylinder diameter having bearing supports encased in a holder on which said horizontally disposed journals are mounted.
  • a device with said four journals has 4 of freedom, increasing its service life term.
  • the longitudinal axes of all said journals are arranged in one vertical plane and in symmetry with the longitudinal axis of the air cylinder.
  • FIG. 1 is a side view with a detail of an apparatus constructed in accordance with the present invention
  • FIG. 2 is a section along llll of FIG. 1.
  • An apparatus for balancing inertial forces of reciprocatingly moving masses of the stand 1 of tube cold rolling mill (not shown in the Figure) comprises an axially disposed air cylinder 2 extending along the rolling axis with piston 3 and plunger 4 connected to the stand 1 by means ofa rocker arm 5 and eye 6. End faces of the air cylinder 2 are provided with covers 7 having packings 8 and through holes.
  • the air cylinder 2 has two vertically disposed journals 9 with bearing supports 10 encased in a holder 11 a (FIG. 2) provided with horizontally secured journals 12, the longitudinal axes of all journals 9 and 12 being arranged in one vertical plane.
  • the bearing supports 10 include bearings 13, located in flanges 14 of the holder 11.
  • the journals 12 of the holder 11 are located in bearing supports 15 which comprise bearings 16 and supporting rings 17 mounted in a stationary housing 18.
  • An apparatus embodying the present invention operates as follows.
  • compressed air is fed into working spaces of air cylinder 1 at a preset initial pressure (a compressed air supply system is not shown in the drawings), resulting in that, with established operating duty of the mill, the elastic reaction-forces of compressed air acting on a stand 1 (FIG. 1) from balancing air cylinder, balance inertial forces developed at reciprocating motion of the stand 1.
  • the rolling of the air cylinder'2 relative to its vertical and horizontal axes allows for excluding additional forces exerted by the stand 1 onto principal compo nents of the balancing device, thus improving their operating conditions and prolonging their service life term.
  • An apparatus for balancing inertial forces of reciprocating masses of a tube cold rolling mill stand which comprises an air cylinder with a plunger, connected with said stand; two journals vertically disposed along the diameter of said cylinder; bearing supports of said vertically disposed journals; a holder encasing said cylinder with said vertically disposed journals; two journals placed into bearing supports and horizontally disposed along the diameter of said cylinder and secured in-said holder.
