Definitions

  • the invention relates to a flanging machine for flanging boiler ends and similar machines comprising a centering device for securing the workpiece in a freely rotatable manner and shaping and smoothing rollers driven by hydraulic motors supplied from a common fluid pressure generator, the shaping roller being preferably pivotally adjustable and the smoothing roller being pivotally and axially adjustable for pressing the workpiece against the shaping roller.
  • the present invention relates to a flanging machine for flanging boiler ends and similar articles.
  • Previously proposed flanging machines have included a clamped workpiece freely rotatable about the axis of a centering device which is engageable by a shaping roller and against which it is pressed by a smoothing roller.
  • Such machines have suffered from the disadvantage that only limited adjustment of only the smoothing roller can be achieved in that the smoothing roller is pivoted to a slide slidable in only one direction with respect to the frame.
  • a flanging machine for flanging boiler ends comprising a frame, a centering device mounted on said frame for securing the workpiece so as to be freely rotatable about the axis of said centering device, a shaping roller mounted on said frame and rotatable about an axis intersecting said axis of said centering device for shaping said workpiece from inside, a first adjustable speed hydraulic motor for driving said shaping roller, a smoothing roller for pressing said workpiece against said shaping roller, a second adjustable speed hydraulic motor for driving said smoothing roller, a slide on which said second hydraulic motor is mounted for axial movement of said smoothing roller in the plane containing the axes of said centering device and said shaping roller, a slide track on which said slide is slidably mounted, a first pressure cylinder for displacing said slide on said slide track, a pivot by means of which said slide track is mounted on said frame for pivotal movement in said plane, a second pressure cylinder for s
  • 1 designates the main part of the machine casing, which also serves as the machine frame.
  • a jib 2 at the top and a carrier 3 at the bottom, which can be detached from it.
  • a respective ram 6 and 7 On each of these two parts 2 and 3 there is disposed a respective ram 6 and 7, each being provided with a respective freely rotatable pressure plate 6b, 7b.
  • the rams are mounted in such a manner that they can be moved away from and towards the main part 1. This reciprocating sliding movement can be effected by mechanical, pneumatic, or electrical means, while additional apparatus may be provided to ensure that the two rams 6 and 7 are situated exactly coaxially to one another in their working positions.
  • the rams 6 and 7 are also slidable towards and away from one another, for which purpose pressure cylinders 4 and 14 respectively are provided.
  • the drawing shows a curved boiler end 5 in the position in which it is held fast by the rams at the commencement of the machining.
  • the shaping roller which shapes the edge of the boiler end into a flange, is here designated by 8.
  • This shaping roller 8 is mounted on a shaping roller shaft 18 which is coupled to the shaft of a hydraulic motor 11.
  • the bearing casing 19 for the shaft 18 is mounted on the main part 1, advantageously in such a manner that the angle formed by the shaft axis 18a with the respective axes 6a and 7a of the rams 6 and 7 can be varied.
  • a sliding track 10 is suspended inside the main part 1 on a pin 9, which may be adjustable for height, about the axis 9a of which it is swingable or pivotable.
  • This axis 911 is perpendicular to the plane containing the axes 6a/ 7a and 18a.
  • the slide track 10 is connected by a pressure cylinder 12 to the main part 1 of the machine casing or frame in such a manner that the pressure cylinder serves as swivelling means for the slide track 10, that is to say it swivels the latter in the clockwise direction when retracted and in the counterclockwise direction when extended.
  • a slide 15 is mounted or suspended slidably on the sliding track 10 and is adapted to be pushed toand-fro by a pressure cylinder 13, of which one end 13a is articulated topthe slide and the other end 13b of which is articulated to the slide track -10.
  • a hydraulic motor 16 is mounted fast on the slide and is coupled to a shaft 20 carrying a smoothing roller 17.
  • the axis 17a of the hydraulic motor 16 and of the smoothing roller 17 lies in the plane containing the axes 6a/7a and 18a, while the sliding track I10 is constructed in such a manner that, on displacement of the slide 15, this position of the axis 17a is always retained.
  • the hydraulic motors 11 and 16 are driven, for anti-slip purposes, from a common pressure fluid generator P.
  • the plate 5 serving as workpiece is first clamped between the pressure plates 6b and 7b of the two rarns 6 and 7, in such a manner that its center lies on the axis 6a/7a.
  • the plate 5 is laid against the shaping roller 8, through lateral movement of the two rams 6 and 7 in such a manner that the flanged edge is formed where it is required.
  • the pressure cylinder 13 is then retracted in such a manner that the smoothing roller 17 lies on the part of the workpiece '5 where the latter lies on the shaping roller 8.
  • the pressure cylinder 12 can now be pressurised with a set pressure and the two hydraulic motors 11 and 16,
  • the pressure applied to the pressure cylinder I12 must be adjusted in accordance with the properties (thickness and strength) of the Workpiece. Because of this joint feeding, slip between the two rollers 8 and 17, or between one of the rollers and the workpiece 5, is avoided. This slipping would necessarily always occur, if a rigid drive was provided for the two rollers, when the instantaneous bearing point of one roller has a different radius from that of the other roller and the two rollers are driven at the same angular velority. By continuous extension of the pressure cylinder 13, the slide 15 is gradually displaced to the left at a speed adapted to the properties of the workpiece.
  • the smoothing roller 17 is guided correspondingly slowly over the entire edge region of the workpiece 5, whereby the desired flanged edge is produced on the latter.
  • the workpiece is removed from the machine, the smoothing roller 17 being first siwung away and the completed boiler and released by raising the ram 6.
  • a flanging machine for flanging boiler ends of the type including a centering device for securing a workpiece so as to be freely rotatable about the axis of the centering device, a shaping roller for shaping the workpiece from inside, and a smoothing roller adjustable during rolling for pressing the workpiece against the shaping roller, with the shaping roller being rotatable for flanging about an axis intersecting the axis of the centering device, and the smoothing roller being pivotally and displaceably mounted, during flanging, in a plane including the axis of the centering device and the axis of the shaping roller; the improvement comprising, in combination, a slideway mounting said smoothing roller for axial displacement; means mounting said slideway for swingable movement about a single axis normal to said plane; and respective hydraulic motors driving said shaping roller and said smoothing roller.
