Definitions

  • the invention relates to roll forming machines and in particular to such machines adapted to form standard cross-sections of various sizes.
  • Roll forming machines of the type under discussion conventionally comprise a series of stands through which the material to be processed is gradually formed into the desired cross-sectional shape, for example a basic channel section.
  • Each stand normally consists of a number of shaped opposed rollers though which the material is passed.
  • rollers at each stand there have been at least four rollers at each stand, two upper rollers and two opposed lower rollers.
  • the rollers being mounted on a single drive shaft running parallel to a similar drive shaft for the lower rollers. If varying widths or depths of channel were required, the width of the raw sheet fed into the machine could be varied as well as the axial spacing between the rollers on their respective shafts.
  • the present invention seeks to overcome these disadvantages by providing a roll forming machine wherein the spacing between axially adjacent rollers can be readily and easily adjusted.
  • the invention consists in a roll forming machine having at least one rolling stand comprising, two or more pairs of upper and lower opposed rollers through which the material to be formed is passed, each roller being mounted on a cantilevered drive shaft which extends towards a drive shaft of an associated roller in another pair, said drive shafts being mounted to allow the axial spacing therebetween to be adjustably varied.
  • the cantilevered drive shafts are mounted in bearing assemblies which are fixedly attached to respective chassis frames which extend the length of the roll forming machine.
  • Each chassis may be supported upon parallel support shafts extending transversely of the machine.
  • each chassis may be altered by means of two or more right and left handedly threaded adjustment shafts also extending transversely of the machine and engaging nuts fixed to a respective chassis.
  • the adjustment shafts may be gear connected to a longitudinally extending drive shaft therefor, so that rotation of the drive shaft causes concerted rotation of the adjustment shafts and thus uniform adjustment of the roller spacing.
  • the longitudinal drive shaft may be driven by any suitable motor gear-box.
  • the invention provides a guillotine for use in conjunction with said roll forming machine, said guillotine having anvil blocks adapted to move with respect to each other to accommodate various sized product from the roll forming machine and a broad guillotine blade adapted to move downwardly between slots provided in said envil blocks, said blade being further adapted to hold said product against the anvil blocks during the guillotining operation.
  • Figure l shows the roll forming machine comprising a main base frame l upon which are mounted on two rafts 8.
  • the rafts are adjustable transversely of the machine by means of shafts l4, l7 and l8.
  • Upper and lower roller pairs 3 and 4 respectively are positioned on stand support frames 5.
  • Each shaft is mounted on the base frame by bearing blocks ll and l9 positioned on either side thereof, as shown in Figure 3.
  • Shaft l7 supports the rafts 8 by means of sliding bearings 20 positioned on each side thereof.
  • the spacing between the rafts 8 is adjusted by means of a pair of ball nuts 22 each attached by means of bracket 2l to the rafts.
  • the ball nuts are driven by two linear screws 24 formed on each end portion of driven shaft 60.
  • the nuts are arranged to have opposing threads to that rotation of shaft 60 in one direction moves the nuts inwardly towards one another and rotation in the other direction moves the nuts outwardly away from one another.
  • Two driven shafts are provided in this embodiment, one at either end of the roll forming machine. These shafts are driven synchronously by a longitudinal drive shaft 7. This shaft is coupled to said driven shafts by means of bevel gears l4 positioned at each end thereof.
  • a drive motor 6 mounted centrally of said roll forming machine rotates the longitudinal drive shaft as required to vary the spacing between the rafts 8.
  • the drive arrangment for the upper and lower rollers will be described with particular reference to figure 5.
  • the lower roller 3l is driven by a chain drive and coupled to drive the upper rollers by means of gear wheels 33 and 66.
  • the lower roller shaft has a pair of co-axially mounted chain sprockets 3l and 32.
  • a motor l0 drives a sprocket 28 which in turn drives shaft 26 via a chain coupled to driven sprocket 29 fixed to shaft 26.
  • Shaft 26 has splined ends for drivably and slidably mounting sprockets 30 and 6l.
  • the shaft is supported by bearing blocks 25.
  • Sprocket 30 is coupled to driven sprocket 32 by a further chain drive (not shown) which drives the lower roller as well as driving sprocket 3l.
  • Driving sprocket 3l drives the driven sprocket of the next roller pair on the roll forming machine.
  • driving sprocket 6l drives driven sprocket 62 and driving sprocket 63 to rotate the lower roller.
  • Bevelled rollers 27 and 69 are mounted on shafts 39 and 40 respectively. These rollers have depressions provided in the surface thereof to give a "dimpled" surface to material 4l being roll-formed therebetween.
  • Shaft 40 is rotated by driven sprocket 32 and is mounted on bearing blocks 36. Each bearing block being supported and attached to a support plate 35.
  • Sprocket 3l is a driving sprocket mounted co-axially and rotating in unison with sprocket 32 as to drive the sprocket of a further roller set.
  • Upper roller 27 is mounted to allow for longitudinal axial movement of the shaft 39. This movement allows upper roller 27 to act as a pressure roller on sheet 4l.
  • the pressure being applied by spring means 37, which preferably comprise disk springs. These springs are held against a bearing carrier block 65 by lock nut means 38.
  • This flexible mounting of shaft 39 enables roller 27 to automatically compensate for varying thicknesses of material 4l.
  • Gear train 33, 66 drives the upper roller in an opposing direction to the lower roller, drawing the material 4l through the roller pair.
  • Figure 7 illustrates an embodiment of the guillotine apparatus according to the invention.
  • the guillotine preferably comprises a broad V-shaped blade 77 mounted movably on a support frame 82 and drivable downwardly by means of a hydraulic ram 78.
  • a pair of split anvil blocks 75 and 76 are located below the blade such that as the blade descends it moves between each half of the split blocks.
  • the blocks are adapted to hold the finished product firmly therebetween during the cutting operation.
  • the spacing between said anvil blocks 75 and 76 is adjustable by means of drive screws 83 and 84 which engage nuts attached to said blocks so that rotation of said drive screws results in inward and outward movement of said blocks relative to each other dependent on the direction of rotation of the screws.
  • Screws 83 and 84 are driven from a main drive shaft 72 by belt drives 85 and 86 coupling pulleys 79, 80 and 73, 74 respectively.
  • Drive screws 83 and 84 are mounted on support plate 7l which in turn is supported on base 8l.
  • the spacing of the anvil blocks is ad usted by means of motor 70 driving shaft 72 to accommodate the width of the product from the roll forming machine.
  • the operation of the machine and in particular the adjustment of the axial spacing is controlled by suitable programmed means, such as a computer or microprocessor.
