Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • 3-roll machines or 4-roll machines are used, which form the cut sheet, which has two opposing, curved edges of different lengths, in one or more passages to form the cone. Since the surface lines of a cone are not parallel to each other, the sheet must not be moved straight through the machines; it must rather change its direction continuously in such a way that the surface lines always run parallel to the roller axes, or, which is synonymous, so that the position of each curved edge which is between the transport rollers always indicates the direction of advance.
  • the conventional roll-sheet metal rounding machines have a brake shoe against which the shorter of the two curved edges rests and from which it is braked, so that the change in direction is ensured.
  • the invention also relates to a roll sheet metal rounding machine having the features of claims 4 and 7.
  • 1 denotes the top roller, 2 the bottom roller, 3 and 4 the two side rollers.
  • the workpiece ie here the finished machined cone jacket, is designated by 5.
  • the bearings of the individual rollers are not shown, and it is known to mount the top roller in such a way that one of its bearings can be folded down so that the finished workpiece can be removed from the machine.
  • the hydraulic cylinders which are used to move the roller bearings and which are shown as if they were acting on the geometric axes of the rollers are only indicated schematically.
  • the hydraulic cylinders of the lower roller are designated with 21 and 22, those of the side rollers with 31 and 32 and 41 respectively.
  • the second cylinder belonging to the side roller 4 is not visible in the drawing. Also not shown in the drawing are the drive elements of the top roller and the bottom roller.
  • a metal plate cut to produce a cone serves as the workpiece. If a straight cone is to be made, the plate has two concentric, arcuate edges and two straight edges connecting these edges, the extensions of which intersect at the center of the arcuate edges. If a slanted cone is to be produced or a cone with a non-circular cross-section, the workpiece naturally has a slightly different shape that is known per se.
  • the workpiece 5 is, as usual, inserted into the roll plate rounding machine and held on the entire length of the workpiece between the upper roll 1 and the lower roll 2. Then its free edge is bent by infeed of the side roller 3 serving as a bending roller. Then the side roller 3 is removed from the workpiece 5 again and the lower roller 2 is pivoted such that the gap opens in the direction toward the hydraulic cylinder 21, as can be seen from FIG. 1, where only the longer arcuate edge 5a of the workpiece 5 is clamped between the two rollers 1 and 2. Now the workpiece is advanced a very small distance by turning the rollers.
  • a brake shoe, not shown, or a controllable clamping device causes the workpiece to pivot so that the surface lines of the workpiece to be generated are located between the two transport rollers 1 and 2.
  • a measuring roller or an optical scanning device that measures the feed at the shorter of the two arcuate edges. The size of this feed can be compared in a computer with the feed caused by the roll rotation on the longer arcuate edge. If the ratio determined in this way does not match the ratio of the lengths of the two arcuate edges entered in the computer, the opening angle of the gap between the rollers is changed or the clamping device is actuated in order to obtain the correct ratio between feed and pivoting. Since such computers, which issue control commands when the measured values deviate from an entered target value, are known per se, they are not described in more detail here.
