Definitions

  • Rolling frames of this type include rolls with one or more roll grooves and which perform rotational oscillating movements; the oscillating roll movement is accomplished by means of cooperating pinions and racks.
  • FIG. 1 is a fragmentary vertical sectional view taken at right angle to the direction of rolling on the line 1-1 of FIG. 2, showing a three-groove rolling frame of a step-back rolling machine for cold rolling;
  • FIG. 2 is a schematic end elevational view parallel to the rolling direction
  • FIG. 3 is a fragmentary sectional view taken on the line 33 of FIG. 2;
  • FIG. 4 is a fragmentary sectional view taken on the line 44 of FIG. 2.
  • FIGS. 1 and 2 there is provided a three-groove rolling frame that comprises two end posts 1 and 2, and a rolling unit 4.
  • the posts 1 and 2 are held together by means of four spacer bolts 3.
  • the rolling unit 4 comprises a lower roll shaft 5 and an upper roll shaft 6, each provided with end pinions; and each sha-ft carries mounted thereon, for instance shrunk thereon, rolls 7; on each side of each roll 7 there is mounted a bearing member 8.
  • Eachbearing member 8 of one shaft is disposed adjacent and opposite a bearing member of the other shaft and is connected thereto to form a bearing housing.
  • the connection of the two bearing members 8 of each housing is made by two bolts 9 which are so pre-tensioned that during rolling there occurs substantially no resilient longitudinal yield by the bolts.
  • each pair of rolls of the two shafts is flanked on each side by a bearing housing that is composed of two bearing members 8; each bearing member 8 journals one of the shafts, and each pair of bearing members is united into a bearing housing by the pre-tensioned bolts 9.
  • a bearing housing that is composed of two bearing members 8; each bearing member 8 journals one of the shafts, and each pair of bearing members is united into a bearing housing by the pre-tensioned bolts 9.
  • three pairs of rolls 7 which have four bearing housings, each composed of a pair of bearing members 8 and held together by the bolts 9.
  • the end bearing housings are mounted on the end posts 1 and 2, respectively.
  • each end post has a U-shaped cut-out that serves as a receptacle, open on top, for the end housing.
  • Each end housing may, as shown in FIG. 3, be in sliding engagement, for instance by a tenon and kerf construction in the U-shaped receptacle, and be supported at the bottom by a raised portion formed in the receptacle.
  • the receptacle is closed by a removable beam 11, which includes a set screw that is mounted on the beam 11 and adjustably bears down on the housing below it in the receptacle.
  • the beam of each end post is held in position by two tiltable holders 12 that are pivoted to the respective end post.
  • the upper shaft 6 carries on each end a pinion 13, and a rack 14 is provided for each pinion 13 of the upper shaft 6 and is in mesh therewith.
  • racks 14 for the upper shaft 6 there are two racks 14 for the upper shaft 6, and each is slidably supported from the respective end post by a wall 16 near the ends of the shaft 6, with the toothed portion facing upwardly.
  • the lower shaft 5 is shorter than the upper shaft 6, and carries at each shaft end two meshing pinions 13 and 15 (see FIGS. 2 and 4).
  • the pinion 13 is mounted on the shaft 5, while the pinion 15 is borne adjacent thereto.
  • the pinion 15 is larger than the pinion 13, and thus is visible behind the pinion 13 in FIG. 1. v.
  • Two racks 14 are assigned to the lower shaft 5 and are slidably supported from the end posts 1 and 2, respectively, near the wall 16, and have their toothed portions facing upwardly.
  • the pinions 13 and their racks 14 of the upper shaft 6 are spaced apart for a greater distance than the pinions 13, 15 and their racks 14 of the lower shaft 5.
  • each end post 1, 2 is provided with a bearing 17 of well-known construction for the connection of the connecting rod 18 for the main drive of the rolling frame.
  • a support including two end posts, a pair of roll shafts operable for oscillating rotary movement supported by said support, a plurality of rolls mounted on each shaft, said rolls being oppositely positioned in pairs on the shafts and defining 7 roll grooves, oscillating driving means for said shafts including pinions mounted on each shaft and racks, each rack meshing with a pinion, and means operable for journalling said roll shafts comprising a series of bearing members journalling each shaft, each roll being disposed between two bearing members, each bearing member of one shaft being disposed opposite and connected to a bearing member of the other shaft and forming therewith a bearing housing, and pre-tensioned bolts connecting the two bearing members of each bearing housing.
  • each shaft being disposed one above the other, each shaft having one pinion mounted on each end, the pinions on the upper shaft meshing with its rack, the racks and pinions of the upper shaft being off-set in the longitudinal shaft direction from the racks and pinions of the lower shaft.
  • the said shafts being disposed one above theother, the lower shaft including a pair of meshing inner and outer pinions on each end, the inner pinions driving said shaft, each outer pinion meshing with the respective inner pinion and with the respective rack.
  • a rolling frame as claimed in claim 1, the two shafts with the rolls and at least some of the pinions and the bearing housings forming a rolling unit, mountable on and dismountable from said support including the racks, as an entity.
  • each post defining a receptacle open on top, the housing on each end of said unit being disposed in said receptacle, and means for closing said receptacles comprising a beam removably positioned'on said post and including means bearing from above against the end housing in each receptacle, and tiltable holders for said beams pivoted on each post.
  • a rolling frame as claimed in claim 4, said racks being supported by said support and having the toothed portion facing upwardly, a pinion supported from each shaft end and being in mesh with a rack, the racks and pinions of the upper shaft being spaced apart for a larger distance than the racks and pinions of the lower shaft, whereby said rolling unit may be lifted, as an entity, off said racks, for dismounting.
