Definitions

  • These machines generally comprise a large number of forming stations, which in the initial machine section generally consist of a motorized unit from which extend two telescopic splined shafts coupled at their opposing ends by a suitable universal joint to two horizontal parallel shafts, of which the upper can be adjusted in level with respect to the fixed lower shaft.
  • the time for equipping the machine for forming pipes of different diameter is reduced to the time necessary for carrying out the following operations on each forming station included in the machine:
  • each individual forming station comprises a base 1, preferably common to all the forming stations.
  • Said base 1 comprises at its top two horizontal parallel guides 2, on which a slide 3 can slide transversely with respect to the axis of the pipe being formed, the sliding movements being controlled in both directions by a double acting cylinder-piston unit 4.
  • Two vertical uprights 5 rise from the slide 3, and between them a slide 6 slides vertically, above a similar member 7 fixed to the base of the uprights.
  • the base 1 10 may also be common to all the forming stations present in the machine.
  • the base 1 On the side opposite the two guides 2, the base 1 carries a locked cylinder-piston unit 12, operated hydraulically, the rod of which carries a member 13. Said member 13 is inserted and locked between two lateral locking guides 14 (see FIG. 3) when the rod of the cylinder-piston unit 12 is lowered.
  • the stroke of the cylinder-piston unit 12 is sufficient to raise the element 13 until it becomes disengaged from the two lateral guides 14, thus enabling it to freely rotate about the axis of the cylinder-piston unit.
  • the female forming rollers 20 are keyed on to the cantilever portion of the shafts 17 and 177.
  • the gears 27 and 28 are similarly engaged with two shafts 33 and 34 projecting in opposing directions from the support connected to the slide 13.
  • the shafts 33 and 34 also carry hand wheels 37 and 38 respectively for manually controlling the small movements of the respective slides, the large initial level adjustments of the slides being made by the geared motor 31.
  • the station is set for forming pipes of a certain diameter, characterised by the shape of the rollers 20 and 22 keyed on the shafts 17 and 19.
  • the machine is stopped, the cylinder-piston unit 4 is then operated to move the slide 3 towards the left, so freeing the ends of the shafts 17 and 19 from the drive unit, together with the end of the upper adjustment shaft 29.
  • the entire element 13 is rotated through to bring the shafts 177 and 199 with the relative new shaped rollers and the adjustment shaft 34 into the working position.
  • said drive means comprises a pair of telescopic members, a first upright nearest said drive means is movable longitudinally of said shaft means from a position supporting one end of each shaft means to a position clear of said shaft means while said drive members telescope, each of said shaft means projects from opposite sides of the other upright for a distance sufficient to enable it to support a forming roller, and said other upright is mounted to rotate about its vertical axis between a first position in which the shaft means projecting from one side of said other upright extend toward said first upright and a second position in which the shaft means projecting from the other side of said other upright extend toward said first upright.
  • Unit as claimed in claim 1 comprising means for raising and lowering said other upright and for locking it in either of its rotational positions when lowered.
  • Unit as claimed in claim 3 in which at least one of the sleeves mounted in said first upright is provided with internal splines which engage external splines on the shaft means received therein, and said splined sleeve is connected to be driven by said drive means.
