Definitions

  • Tube rolling on taper plug impairs the quality of tube causing the corrugated inner surface and uneven wall thickness.
  • tube cold rolling method wherein no rolling takes place during the backward stroke of the working stand as during this stroke the roll passes are parted without contacting the tube being rolled.
  • the object of the present invention is to provide a tube cold rolling method allowing the productivity of the rolling process to be substantially increased and the quality of rolled tubes to be improved.
  • the method of cold rolling of tubes periodically delivered by the feed chuck to the deformation zone utilizes a roll stand 1 and roller stand 2 positioned in a straightaway setup and reciprocated in opposite directions.
  • the roll stand 1 is reciprocated from a motor through a crank and connecting-rod gear, while the roller stand 2 is reciprocated from the roll stand 1 by means of rack-and-gear drive 3.
  • the roll stand 1 incorporates periodic passes 4. All profile sections of the passes 4 are roughing, which allows the tube 5 to be rolled in the passes of the roll stand 1 with maximum possible deformation of the tube 5 both in diameter and wall thickness, thus giving a substantial increase in productivity as compared with conventional roll stands.
  • sizing of the tube in diameter and wall thickness is effected in the roller stand 2 on a cylindrical plug 6 by rollers 7 with constant-section groove, the latter rollers running along straight supporting strips 8 and the tube rolling operations kept continuous. This makes possible to eliminate all intermediate technological operations needed after rolling tubes in stands to prepare tubes for rolling and sizing in roller stands, namely cutting, annealing, pickling, straightening, copper plating, phosphating and lubrication.
  • the tube rolling process starts in the roll stand 1 on the taper plug 9 after bringing a tube billet to the deformation zone with the stand 1 moving forward, complete rough deformation (reduction) of the tube 5 in diameter and wall thickness taking place during this period. Further sizing of the tube in diameter and wall thickness, also rolling off buckle and surface polishing of the tube 5 are effected in' the roller stand 2 on the cylindrical plug 6 by rollers 7 with constant groove section.
  • the taper plug 9 of the roll stand 1 and the cylindrical plug 6 of the roller stand 2 are screwed on a common bar 10.
