Definitions

  • the currently employed support frame mounting the horizontal and vertical rolls must be run out of the universal rolling mill of lthe aforementioned type. This support frame is then exchanged for another that in the meantime was set up for the next size of stock to be reduced. When this new size of stock is being rolled the support frame in the run out position is set up in readiness for the next change of schedule.
  • the object of this invention is to reduce the time required for changing the set-up of a support frame for a change of rolling schedule, when said support frame is in the run-out position and reduction of the current size stock is proceeding.
  • the invention is thus basically addressed to a method of changing the roll set-up of a universal mill that permits the horizontal rolls to be replaced without dismantling the vertical rolls.
  • the basic means of arriving at the desired solution consist of first placing the lower horizontal roll complete with chocks on the carriage, then positioning the support frame mounting the vertical rolls on the carriage, after which the upper horizontal roll is lowered into the support frame before the support frame resting on the carriage is traversed into the windows of the roll housings.
  • the applicants method permits the time required for a change of rolling schedule to be substantially reduced.
  • the invention provides for the support frame that has been run out of the universal mill for a change of set-up, and after the upper horizontal roll with its chocks has been picked out, to be lifted up with the vertical rolls from the carriage, leav- 3,525,244- Patented Aug. 25, 1970 ice ing the lower horizontal roll in position, and to he immediately set down on another, previously prepared carriage mounting a lower horizontal roll for the next size of stock to be reduced. All that remains to be done is for the new upper horizontal roll to be installed from above in the support frame, and the latter is then ready to be shifted into the operative position for the reduction of the next item on the mill schedule.
  • the invention offers a further substantial advantage of reducing the hook load on the crane employed for the roll changing work.
  • the invention permits the load to be divided into the upper horizontal roll, the support frame mounting the vertical rolls, and the lower horizontal roll. The applicant has made this possible by simple means, ⁇ by designing the support frame with openings at the top and bottom for installing the horizontal rolls.
  • FIG. 1 shows in detail a universal mill viewed in the direction of rolling, from which, for the sake of clarity the support frame mounting the horizontal and vertical rolls, has been traversed out of the roll housings.
  • FIG. 2 shows the side view, partly in section, of the universal mill depicted in FIG. 1.
  • the universal rolling mill 3 has two horizontal rolls 1 and two vertical rolls 2. With the aid of a carriage 9 a support frame 8 can be laterally traversed into the windows 6 of the two housings 7 comprising the roll stand 3.
  • This support frame 8 accommodates both the horizontalrolls 1 with their chocks and, to the side thereof but on the same plane, the vertical rolls 2 with their chocks.
  • a quick change in the production schedule is made possible in that all that has to be done is to traverse the support frame 8 laterally out of the windows in the housings 7 and to run in another, previously set-up support frame 8 for the next size of stock to be reduced, into the windows 6 of the housings 7 with the aid of a carriage 9.
  • the upper horizontal roll 1 together with its chocks is removed from the frame 8.
  • the frame 8 together with the vertical rolls 2 and their chocks are lifted olf the carriage 9, leaving the lower horizontal roll 1 to be removed.
  • a substitute lower roll is placed on the carriage followed by the frame 8, including the original vertical rolls 2. All that then remains to be done is for the new upper horizontal roll 1 to be lowered into the support frame 8, and the set-up is thus completed for the new production run.
  • said frame (8) made up of spaced vertical walls between which are received and supporting said vertical rolls in their working positions, together with their bearing-chock assemblies, and having a support surface for the bearing-chock assemblies of said upper horizontal roll,
  • a carriage (9) constructed and arranged to move between a first position outside said window to a second position within said window and having a support surface for the bearing-chock assemblies of said lower horizontal roll,
  • said carriage (9) also having a support surface for said frame (8),
  • said frame having openings at its top and bottom for receiving the upper and lower horizontal rolls (1), respectively, in a manner that when in its said rst position, the lower horizontal roll is mounted on said carriage after which said frame with the vertical rolls is mounted on said carriage (9) and then said upper horizontal roll is mounted on said frame, and
  • a method of mounting the rolls of a universal mill to facilitate the quick assembly and disassembly of the horizontal rolls thereof, said mill having an upper horizontal roll and a lower horizontal roll and a pair of vertical rolls comprising the steps of:
