Definitions

  • This invention relates to roll-forming machines and particularly to roll-forming heads for such machines.
  • Known roll-forming machines include heads which comprise rolls configured to form the required shapes in panels and the like. These machines, however, present a major disadvantage in that, in order to change the shape imparted to panels passing through the machine, it is necessary to remove and replace the rolls, which can take many man hours and require the machine to be out of use for a considerable time.
  • a roll-forming machine comprising a roll-forming head including shafts or spindles for mounting two series of rolls, the head being adjustable so that the shafts or spindles can be arranged to permit either series of rolls to be brought into an operable position.
  • FIG. 1 is a fragmentary perspective view of arollforming machine incorporating a roll-forming head according to the present'invention
  • FIG. 2 is a fragmentary side view to the rolls
  • FIG. 3 is a view corresponding to FIG. 2 showing the drive disconnected to permit adjustment of the head
  • FIG. 4 is a section of the line IVIV of FIG. 3.
  • a roll-forming machine for imparting a shape to two parallel edges of a panel.
  • This machine comprises a base supporting two laterallyspaced sub-bases 11 each of which supports a rollforming head 12, and means 13 for driving the rolls of the heads 12.
  • Each head 12 comprises a frame 14 supporting a series of pairs of parallel, vertically-spaced shafts or spindles 15 which traverse the frame 14.
  • a forming roll 16 can be attached to either end of each shaft or spindle 15, the roll 16 at one end of each shaft or spindle 15 being of different shape from that at'the other end.
  • the shafts or spindles 15 are driven by gearwheels 17 disposed intermediate the ends of the shafts or spindles l5 centrally of the frame 14.
  • Each forming head frame 14 has a ring 18 fixed thereto at its center this ring being of diameter just sufficient to fit inside a ring 19 fixed to the corresponding sub-base ll of the machine.
  • An annular groove 20 on the outer edge of the inner ring 18 is engaged by a grub screw 21 passing through the outer ring 19.
  • the forming head 12 may revolve on the sub-base 11 as the ring 18 turns inside the ring 19.
  • the head 12 at one end is provided at each side with'an apertured block 22 adapted to be aligned with an aperture 23 on its sub-base 11, a locking pin 24 being secured by a chain 25 to the sub-base l1 and being adapted to pass through the apertured block 22 and aperture 23 to secure the head 12 in position.
  • the drive to the rolls 16 of each head 12 is from a motor 26 via chain wheels 27 and 28 and a chain 29, which chain transmission is central to the sub-frame 11.
  • the chain wheel 28 is fast on a spindle 30 which mounts another chain wheel 31 on the inner side of the showing the drive vertically adjustable as an assembly and for this purpose are carried by a block 37 at each side of the subframe 11, which blocks 37 are vertically slidable in slots 38.
  • a cam 39 engages each of the blocks 37 and is rotatable by a handle 40.
  • the heads 12 When it is desired to change the shape to be imparted to a panel passing through the machine, the heads 12 may be revolved to present the other forming rolls to the panel.
  • the assembly 33, 34 and 35 is lowered, the chain 32 being held taut by a spring loaded jockey 41, the head 12 is revolved, pins 24 are placed in position to hold the head 12 stationary, and the assembly 33, 34 and 35 is lifted to engage the drive of the head.
  • one of the heads is conveniently adjustable laterally. This is achieved by having its sub-base 11 slidable laterally, the chainwheel 31 and 33 sliding over their spindles to" which they are keyed as the sub-base is moved.
  • either of the roll-forming head 12 may be easily removed and replaced by unscrewing the grub screw 21 in the outer ring 19 and lifting the head 12 off the sub-base 11.
  • a roll-forming machine comprising:
  • a roll-forming head detachably supported on the frame and rotatable about a vertical axis
  • a second ring mounted on the roll-forming head and disposed within the first ring, the rings being coaxial and relatively rotatable and their axis being the axis of rotation of the roll-forming head;
  • a machine as claimed in claim 1 in which there are a pair of parallel roll-forming heads, each rotatable bodily relative to the frame to bring the desired series of forming rolls to the operative position.
  • a machine as claimed in claim 1, in which the means for axially restraining'the rings is a screw carried by the outer ring for engaging in a circumferential groove formed in the outer circumference of the inner ring.
  • a carrier means vertically slidable in the frame and supporting the drive gearwheel, spindle, and transmission wheel, and
  • cam means for moving the carrier means be tween 21 position whereat the drive gearwheel meshes with said one of the shaft gearwheels and a position whereat they are out of mesh.
