Definitions

  • the invention relates to a roller tool for linear sheet metal deformation according to the preamble of claim 1. Furthermore, the invention relates to a sheet metal forming device with such a roller tool.
  • Such a roller tool and a sheet metal forming device with such a roller tool are known from DE 695 10 771 T2. With such a sheet metal forming device straight deformations can be generated in a workpiece. The generation of bent deformations is not possible.
  • the roller body has a plurality of independently rotatable roller discs, generation of bent deformations in a workpiece is readily possible.
  • the bow inner roller disc can then rotate slower than the bow outer roller disc, so that stresses and shear forces that did not allow the generation of bent deformations in the known roller tools, no longer occur.
  • a differential is created, which also allows the production of curved deformations.
  • roller bodies with the different variants of roller disc numbers according to claim 2 have proven to be particularly useful for the practice.
  • a profiling supplement according to claims 3 and 4 results in a reel body with seamless, circumferential profiling. This results in beads with a defined and seamless cross section in both the straight sections and in the bow sections.
  • a counter-body according to claim 5 cooperates advantageously with the roller body for sheet metal deformation.
  • a counter-body according to claim 6 has the same principal advantages as the roller body according to the invention.
  • the counterbody may also be constructed like the roller body from a plurality of roller discs.
  • a arranged according to claim 7 sleeve facilitates the production of the reel body or the counter body in particular when this is composed of a larger number of individual discs.
  • a lubricating device enables automated lubrication of the roller body and / or the counter body.
  • a lubricating device elegantly provides the lubricant where it is needed for lubrication.
  • the lubricant reservoir can be designed so large that the lubrication is ensured over a long period of time until a refill of the lubricant reservoir, z. B. on a standard grease nipple, which is accessible from the outside, is required.
  • a lubricant z. B. a penetrating oil are used.
  • a plurality of connecting channels according to claim 10 enables a uniform lubrication of the roller body and / or the counter body.
  • connection channels according to claim 11 There is also ensured that a circumferentially around the shaft unilateral load of the roller body and / or the counter body does not lead to an unwanted closure of all connecting channels in the region of their mouths from the shell wall.
  • An energy accumulator according to claim 12 leads to a secure lubricant supply.
  • the lubricant supply z. B. be ensured by the influence of gravity, by the creep ability of the lubricant or by a capillary effect.
  • Another object of the invention is to provide a sheet metal forming device with which curved linear deformations in sheets can be produced.
  • a sheet metal forming apparatus 1 which is cut and broken in FIG. 1 serves for line-shaped sheet metal deformation, in particular for the formation of beads.
  • the sheet metal forming apparatus 1 comprises a roller tool 2, which is held by a roller tool holder 5 which is shown schematically only in cutouts 3, 4.
  • the roller tool holder 5 is, as indicated schematically in Fig. 1, with a drive 6 in connection. With the help of the drive 6 pivoting or rotation of the roller tool holder 5 together with the roller tool 2 about a pivot or rotation axis 7 is possible.
  • the pivot axis 7 is perpendicular to a currently machined with the roller tool 2 sheet, which is not shown in the drawing.
  • the roller tool 2 has a press roller 8, which is arranged in FIG. 1 below a sheet metal deformation zone 9 of the sheet metal deformation device 1.
  • the press roller 8 cooperates with a hydraulically actuated counter-body 10 in the sheet-metal deformation zone 9.
  • the sheet to be processed is arranged in the sheet deformation zone 9 between the press roll 8 and the counter body 10 such that the sheet surface is oriented horizontally perpendicular to the drawing plane of FIG. 1 and in FIG. 1.
  • the press roller 8 has a shaft 11 and a roller body rolling about it 12 on. Between the shaft 11 and the roller body 12, a sleeve 13 is arranged, whose extension along the shaft 11 corresponds to that of the roller body 12. The sleeve 13 is rotatable about the shaft 11.
  • the roller body is divided into a plurality of individual roller discs 14 to 23, which are numbered ascending in Fig. 3 from bottom left to top right.
  • the pulleys 14 to 23 are adjacent to each other and together form the applicable to the sheet to be machined portion of the roller body 12.
  • the pulleys 14 to 23 can rotate independently of each other around the sleeve 13 and thus also about the shaft 11.
  • the abutting surfaces of the roller discs 14 to 23 are lubricated.
  • a total of ten roller disks 14 to 23 are present.
  • the ten roller discs 14 to 23 form a roller disc package.
  • the roller discs 14 to 23 each have lateral surfaces, which complement each other seamlessly to a peripheral profiling of the roller body 12, as shown particularly in FIG. 4 can be seen.
  • the circumferential profiling of the roller body 12 has a central circumferential bead 24, with which the bead is produced in the sheet to be machined.
  • This bead 24, which represents a convex profile section of the circumferential profiling of the roller body 12, is formed from the lateral surfaces of the four central roller discs 17 to 20.
  • the peripheral roller discs 14 to 16 and 21 to 23 are designed as rings with flat lateral surfaces.
  • the counter-body 10 is also formed as a roller with a counter-body shaft 25 and a rolling around this counter-roller body 26.
  • the counter-reel body 26 has two annular rollers 27, 28 which extend can rotate independently of each other about the counter-body shaft 25. Between the rollers 27, 28, a spacer sleeve 29 is disposed on the counter-body shaft 25. Between the counter-body shaft 25 and the counter-roller body 26, a counter-body sleeve 30 is arranged. The two rollers 27, 28 are independently rotatable about the counter-body shaft 25.
  • the shafts 11, 25 are rotatably held by grub screws 31 in corresponding shaft receptacles 32.
  • the sheet metal forming apparatus 1 operates as follows: After the sheet to be processed has been introduced into the sheet metal deformation zone 9 between the press roll 8 and the counter body 10, the counter body 10 is fed hydraulically onto the press roll 8. If a predetermined pressing force between the press roller 8 and the counter body 10 is present, the roller tool 2 moves linear relative to the plane of the sheet, wherein the shape of the bead to be formed is traced. The bead does not have to run straight along the sheet, but in particular can also be curved or curved. To form such a bent bead, the roller tool 2 moves the lines of the bead according to such that the shafts 11, 25 are at any time approximately perpendicular to the beading section consformenden. For this purpose, the roller tool 2 is rotated about the drive 6 about the pivot axis 7 each in the required pivot position, while the bead is traversed.
  • the bow outer pulleys 14 to 23 and the bow outer roller 27, 28 have to travel a greater distance than the inner bow pulleys 14 to 23 and the inner bow roller 27, 28.
  • the outer components of the arc which abut the sheet to be machined, then rotate faster than the adjacent sheet metal arc components.
  • the subdivision of the roller body 12 in the roller discs 14 to 23 on the one hand and the subdivision of the counter body 10 in the rollers 27, 28 therefore act as a differential when descending a bent bead portion.
  • roller tool 2 and the counter body 10 is constructed of a plurality of counter-body pulleys, which together form a roller package, in particular with a profiling of the roll package 12 of the roller body complementary profiling.
  • roller body 12 has three, five or eight roller discs.
  • FIGS. 1 to 6 A further embodiment of a counter body 33 for use in a sheet metal forming device such as that described above with reference to FIGS. 1 to 6, Figs. 7 to 9 show components which correspond to those as already described above with reference to FIGS Figs. 1 to 6 have been explained, bear the same reference numerals and will not be discussed again in detail.
  • the counter body 33 has rollers 34, 35, between which a spacer sleeve 36 is arranged. Except for sizing differences, the rollers 34, 35 and the spacer sleeve 36 correspond to the rollers 27, 28 and the spacer sleeve 29 of the embodiment of the counter body 10 of FIGS. 1 to 6.
  • the counter body 33 has no counter-body sleeve 30.
  • a counter-body shaft 37th has a lubricant reservoir 38 in the form of a central, along the shaft 37 extending blind bore. On the front side, in FIGS. 7 and 8 to the right, the lubricant reservoir 38 is closed by a commercially available lubricating nipple 39 with a check valve.
  • a compression spring 40 is arranged in the lubricant reservoir 38, which is supported on one side at the bottom of the blind bore and on the other side on a plunger 41. With the help of the plunger 41, the compression spring 40 exerts pressure on the contents of the lubricant reservoir 38, that is, on the lubricant there in the form z. As a creeping oil.
  • the lubricant reservoir 38 is in fluid connection with an outer jacket wall 45 via a plurality of connecting channels 42 to 44 designed as branch lines.
  • three equidistantly arranged connection channels 42 to 44 are provided, all of which open downwards, so that even without action of the compression spring 40, a lubricant outlet occurs under the influence of gravity.
  • a lubricant outlet can also take place without the influence of the compression spring and without the influence of gravity due to a creeping ability of the lubricant or due to a capillary effect.
  • a lubricant outlet can also take place under the influence of a thermal expansion of the lubricant during operation of the sheet metal forming device 1.
  • connection channels are possible.
  • a counter-body lubricating device 46 is formed. Accordingly, a roller body lubricating device can be constructed. There, in particular, the number and arrangement of the connecting channels can be adapted to the number and the strength of the roller discs 14 to 23. Thus, a roller body lubricating device z. B. have as many connecting channels as roller discs are present.
