Definitions

  • the invention relates to a roller burnishing tool for producing a tooth structure in the wall of a preform. It is generally about producing a spline in the wall of a cylindrical blank to produce a gear.
  • Such a roller burnishing tool comprises disc-like rollers which are rotatably mounted.
  • the rollers are arranged such that their peripheral edges roll along the lateral surface of the cylindrical blank, applying a pressure to the lateral surface, so that the lateral surface is pressed in, whereby a tooth space is formed.
  • the rollers run - seen in plan view of the cylindrical blank - more or less radially to this.
  • a so-called stamp is provided within the blank. This fills the interior of the blank.
  • the punch is toothed in the manner of a gear, so that when creating a tooth gap through one of said disc-shaped rollers, a tooth of the punch from the inside presses on the wall of the cylindrical blank while pressing material between two adjacent rollers outward and thus forms a tooth on the blank ,
  • EP 2 282 854 B1 which describes a Rollumformmaschinen.
  • DE 2 017 709 describes a tool for rolling longitudinal grooves in cylindrical workpieces, wherein the profile rollers are movably mounted in the direction of the rolling force.
  • Each profile roller is supported by two support rollers touching the profile roller at its circumference, which are mounted in a receiving body.
  • an adjusting wedge is provided, which can be adjusted by two lag screws.
  • a disadvantage of this arrangement is that an exchange of the profile rollers, for example by a roller with a new outer contour for producing a different teeth, only with a simultaneous adjustment, in particular an exchange of the support rollers can be done and the entire arrangement a large space requirement and an unfavorable load application has in the various components.
  • DE 10 2009 044 544 A1 describes a forming device and a Einrichthabilit for introducing an internal and external teeth in a cylindrical workpiece, in which the profile rollers are mounted for adjustment on eccentric bushes.
  • EP 0 761 338 A1 discloses a roller burnishing tool for producing a tooth structure in a wall of a cylindrical blank, wherein a wedge-shaped intermediate body is provided, and wherein radial forces arising are taken up exclusively by the rollers radially supporting abutments, but not by a cage which holds the profile rollers in a common plane.
  • the serving for supporting the rollers shafts or bolts are essentially free of forces.
  • the invention has for its object to design a roller burnishing tool according to the preamble of claim 1 such that you can respond quickly and with little effort to deviations of the workpiece.
  • the roller burnishing tool is intended to provide, in particular, an alternative to the conventional adaptation of the penetration depth or the profile of the rollers, which is improved in terms of installation space and costs, as well as in terms of service life.
  • an intermediate body is advantageously provided. This exerts a pressure on the bearing journals of the rollers, so that they are displaced against the lateral surface of the blank. Each intermediate body is supported by a fixed environment.
  • the intermediate body is wedge-shaped.
  • the contact pressure can be adjusted by adjusting the position of the wedge-shaped intermediate body.
  • the position of the intermediate body in a feed direction for producing a relative movement between the rollers and the blank is determined by at least one replaceable spacer.
  • the at least one spacer is formed by at least one interchangeable positioning ring or interchangeable positioning ring segment, typically a plurality of circumferentially spaced positioning ring segments.
  • the wedge-shaped intermediate body can be enclosed on both sides by exchangeable spacers, in particular exchangeable positioning rings or exchangeable positioning ring segments, in the aforementioned feed direction for generating the relative movement.
  • the spacer in particular the at least one positioning ring or the positioning ring segments, can be detachably connected to the intermediate body, in particular screwed.
  • a hydrostatic pressure chamber is provided.
  • this may for example have a space which can be connected to a hydrostatic pressure medium in order to inflate the said space more or less and thus to change the dimension of the intermediate body in the pressing direction.
  • the intermediate body or another element which exerts the contact pressure at least indirectly can be tempered, preferably by means of electrical resistance heating. Again, this allows the distance between the rollers change relative to the blank.
  • changing the position of the rollers relative to the blank may even be advantageously done during operation, at least without any rebuilding or removal of the rollers.
  • Rolling tool shown comprises the following components: One of numerous rollers 1 (roller burnishing) is rotatably mounted on a journal 2.
  • the bearing journal 2 is in turn mounted in a housing 3.
  • the housing 3 is fixed in a so-called boiler house 4, which has a cover 5.
  • a blank 6 has the shape of a cylindrical hollow body with a closed bottom 6.1 and a cylindrical wall 6.2.
  • the blank 6 is made of a blank by deep drawing.
  • the circuit board is a circular steel disk.
  • 1 grooves must be pressed into the wall 6.2 by rolling by means of the rollers. This is done in the present case in that the blank 6 is moved from an upper position I shown here in a lower position II also shown.
  • the roller 1 is mounted and arranged so that it pushes the wall 6.2 when lowering the blank 6 inward. In each case two adjacent rollers 1 form a tooth which is parallel to the feed direction 7 of the blank 6.
  • the blank 6 is clamped between a counter-holder 8 and a punch 9.
  • the counter-holder 8 is fixedly connected to a quill 10, for example by screwing.
  • the punch 9 is located inside the blank 6. It is itself shaped like a gear. The teeth of the punch 9 work together during rolling process with the rollers 1 by one tooth of the punch 9 engages between two adjacent rollers 1.
  • an intermediate body 11 is provided. This is preferably designed as a wedge ring and surrounds all rollers 1 with the plurality of housings 3 and the center arranged in the blank 6. The arrangement of the wedge ring is made FIG. 2 seen.
  • the intermediate body 11 may be divided into numerous individual bodies or be made in one piece.
  • the radial position of the rollers 1 can be adjusted by means of the wedge-shaped intermediate body 11. How to get out FIG. 1 the further the wedge-shaped intermediate body 11 is driven into the receiving space 12, the deeper penetrates the peripheral edge of the single roller 1 in the material of the blank 6 and thus the tooth height becomes greater ,
  • the boiler house 4 is stationary with the housings 3 and rollers 1 arranged therein.
  • the preform 6 performs the already mentioned translatory movement in the feed direction 7, here from top to bottom, optionally also from bottom to top.
  • the blank 6 takes in its translational movement, the rollers 1 by frictional engagement with and thus puts these in circulation.
  • the rollers 1 thus need no own drive.
  • the position of the intermediate body 11 in the feed direction 7 is defined by exchangeable positioning rings 14.
  • the positioning rings 14 may be designed as circumferentially closed rings. However, they can also be formed by a plurality of individual spaced from each other or adjacent to each other positioned ring segments. Finally, instead of the positioning rings 14 and not annular spacers can be used. By the spacers, here the positioning rings 14, with the position of the intermediate body 11 in the feed direction 7 at the same time the penetration depth of the disc-shaped rollers 1 is defined in the material of the blank 6. Thus, the penetration depth can be changed by inserting accordingly in their thickness (height) designed positioning 14.
  • the positioning ring 14 in the feed direction 7 at the narrow end of the receiving space 12 is comparatively thin, so the wedge-shaped intermediate body 11 immersed deeper into the tapered receiving space 12 a and pushes the housing 3 adjacent to it and thus over the bearing journal 2, the roller 1 comparatively further in the direction of the blank 6. If, however, (in the drawing below in the receiving space 12) a comparatively thicker positioning ring 14 is inserted, the intermediate body 11 in Direction shifted to the other portion of the receiving space 12, so that the housing 3 with the roller 1 in the direction of the supporting fixed environment, here the boiler house 4, press and the role 1 dives less in the wall 6.2 of the blank 6 a.
  • the bearing journals 2 have a special shape, which can also be embodied independently of the features described further in this exemplary embodiment.
  • This flattening 13 is in the FIGS. 1 . 2 and 3 seen.
  • the flats 13 are provided on the peripheral portion of the bearing pin 2, in the direction of the fixed Environment in which the housing 3 supported by the or the intermediate body 11, positioned.
  • a flattening 13 may, for example, as shown in FIG. 2 it can be seen, pass over in each case a chamfer or bevel in the circumferential direction in the round, in particular circular peripheral region of the journal 2.
  • the mating contour in the housing 3 does not have to be designed identically; there, for example, a round or rounded transition in the circumferential direction from the region of the flattening into the round or circular circumferential section is possible.
  • the housings 3 likewise have a planar contact surface on their outer side facing the intermediate body 11, in contrast to an annular bearing surface. This also leads to a more favorable surface pressure.
  • the intermediate body or bodies 11 accordingly have at their inner periphery, which faces the blank 6 is, flat contact surfaces and form, as from the FIG. 3 is particularly well visible, on its inner circumference a polygon.
  • the one or more intermediate body 11 may be annular, but this is not mandatory, depending on the design of the contact surface of the fixed environment, here the boiler house. 4
  • the rollers 1 are mounted exclusively on the bearing journal 2, thus no support rollers or the like are provided or support areas on the outer circumference of the rollers 1.
  • a roller 1 having a first outer contour, which forms a first type of toothing replace with another roller 1 with a different contour for a different type of toothing.
  • the housing 3 it is also easily possible by the design of the housing 3 to take these together with the rollers 1 from the areas between the wedge segments 15. So are always two housing 3 or housing parts angular, in particular designed L-shaped and form in the assembled state a U-shape, in each of which a roll 1 or here a pair of rollers 1 is added. At the outer end, the legs of the L-shaped housing parts abut each other and at the inner end of the distance is defined and secured by the bearing pin 2 used.
  • a Schmierölnut 18 may be introduced, which here in the FIG. 2 can be seen and this is carried out on top of the journal 2.
  • rollers 1 shown here wherein in each case two Rotten1 adjacent to each other in a housing formed from two parts 3 or in two adjacent housing 3 is used, offers the advantage that comparatively small rollers 1 can be used in their diameter, without that the risk of a collision of the components carrying them over the circumference of the blank 6 threatens.
  • a particularly compact embodiment can be created.
  • two spacers preferably in the form of positioning rings 14 or two groups of spacers or positioning ring segments are provided, namely a spacer or a first group under the one or more intermediate bodies 11 and a second spacer or a second group above the or Intermediate bodies 11.
  • These two spacers or groups of spacers together form each a constant height, so that an exchange of the or the intermediate body 11 for setting different penetration depths of the rollers 1 in the blank 6 is not necessary.
  • a spacer or a group of spacers could possibly be dispensed with.
  • spacers are screwed to the intermediate body 11. This is particularly advantageous when a plurality of spacers over the circumference of an intermediate body 11 or a plurality of intermediate bodies 11 over the circumference of the blank 6 is used.
  • intermediate body 11 can have a space which can be connected to a hydrostatic pressure medium, for example to a pressure oil, and which can inflate said space and thus increase the dimension of the intermediate body 11 in the pressing direction. You can also get one Integrate hydrostatic space in the boiler house or in the housing. Then the intermediate body 11 can be omitted.
  • the invention can be applied not only in the production of gradveriereten gears, but also in helical gears. It does not even have to be gears, but it come for the application of the invention, any teeth into consideration, even on non-rotating components.
