Definitions

  • the invention relates to a burnishing tool for producing a toothed structure in the wall of a preform. In general, this involves the production of splines in the wall of a cylindrical blank in order to produce a gear wheel.
  • Such a roller burnishing tool comprises disc-like rollers that are rotatably mounted.
  • the rollers are arranged such that their peripheral edges roll along the lateral surface of the cylindrical blank while exerting a pressure on the lateral surface so that the lateral surface is indented, forming a tooth gap.
  • a variety of roles are associated with the preform. The roles run - viewed in plan view of the cylindrical blank - more or less radially to this.
  • a so-called stamp is provided inside the blank. This fills the interior of the blank.
  • the stamp is toothed in the manner of a gear wheel, so that when a tooth gap is created by one of the disc-shaped rollers mentioned, a tooth of the stamp presses from the inside onto the wall of the cylindrical blank, thereby pushing material between two adjacent rollers outwards and thus forming a tooth on the blank .
  • the aim is to produce an end product that will maintain the specified dimensions with a high level of accuracy. This applies in particular to the width of the tooth gaps. However, it has been shown again and again that this requirement cannot be met. Deviations from the target dimension are primarily due to differences in the quality of the steel used. This can lead to significant deviations from the target dimensions when using qualitatively different steel batches.
  • roller burnishing tool changes must be made to the roller burnishing tool. In particular, it is then necessary to replace the disk-shaped rollers. If the roller burnishing process leads to excessively deep tooth gaps, then rollers with a small diameter must be selected, and vice versa. Such change processes are time-consuming and expensive. In particular, a large stock of burnishing rollers is required. If there are dimensional deviations in the workpiece, the current rollers must be removed from the roller burnishing tool, suitable roller rollers selected from stock and installed.
  • DE 2 017 709 describes a tool for rolling longitudinal grooves into cylindrical workpieces, the profile rollers being movably mounted in the direction of the rolling force.
  • Each profile roller is supported by two support rollers which touch the profile roller on their circumference and are mounted in a receiving body.
  • An adjustment wedge is provided between each receiving body and an inner wall of a reinforcement ring, which can be adjusted by two tension screws.
  • the disadvantage of this arrangement is that the profile rollers can only be replaced, for example by a roller with a new outer contour to produce a different type of toothing, with a simultaneous adjustment, in particular an exchange of the support rollers, and the entire arrangement requires a large amount of space and an unfavorable load introduction into the various components.
  • DE 10 2009 044 544 A1 describes a forming device and a setup method for introducing internal and external teeth into a cylindrical workpiece, in which the profile rollers are mounted on eccentric bushes for adjustment.
  • DE 10 2008 017 608 B3 and DE 10 2007 062 361 A1 referred.
  • EP 0 761 338 A1 discloses a burnishing tool for producing a tooth structure in a wall of a cylindrical blank, with a wedge-shaped intermediate body being provided, and with radial forces arising being absorbed exclusively by abutments that radially support the rollers, but not by a cage that holds the profile rollers in a common plane.
  • the shafts or bolts used to support the rollers are essentially force-free.
  • the invention is based on the object of designing a burnishing tool in accordance with the preamble of claim 1 in such a way that one can react quickly and with little effort to dimensional deviations of the workpiece.
  • the roller burnishing tool is intended to provide an alternative to the conventional adaptation of the penetration depth or the profile of the rollers that is improved in terms of installation space and costs as well as in terms of service life.
  • An intermediate body is advantageously provided for all three main ideas. This exerts pressure on the bearing journals of the rollers so that they are pushed against the outer surface of the blank. Each intermediate body is supported on 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 generating a relative movement between the rollers and the blank is determined by at least one exchangeable spacer.
  • the at least one spacer is formed by at least one exchangeable positioning ring or an exchangeable positioning ring segment, generally a multiplicity of positioning ring segments arranged distributed over the circumference.
  • the wedge-shaped intermediate body in the feed direction mentioned for generating the relative movement can be enclosed on both sides by exchangeable spacers, in particular by exchangeable positioning rings or exchangeable positioning ring segments.
  • the wedge-shaped intermediate body which is advantageously designed as a wedge ring, rests on at least one spacer element, advantageously at least one positioning ring or a large number of positioning ring segments, and is carried by it.
  • the spacer in particular the at least one positioning ring or the positioning ring segments, can be detachably connected, in particular screwed, to the intermediate body.
  • an intermediate body which includes a hydrostatic pressure chamber.
  • the hydrostatic chamber can be connected to a hydrostatic pressure medium in order to inflate said chamber to a greater or lesser extent and thus change the dimensions of the intermediate body in the pressing direction.
  • the temperature of the intermediate body or another element that exerts the contact pressure at least indirectly can be controlled, preferably by means of electrical resistance heating. This also allows the distance between the rollers to be changed relative to the blank.
  • the position of the rollers relative to the blank can be changed advantageously during operation, at least without any modification or removal of the rollers.
  • the roller burnishing tool shown comprises the following components: One of numerous rollers 1 (roller rollers) is rotatably mounted on a bearing pin 2 .
  • the bearing pin 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 from a blank by deep drawing.
  • the circuit board is a circular steel disk.
  • grooves must be pressed into the wall 6.2 by rolling using the rollers 1. In the present case, this occurs in that the blank 6 is shifted from an upper position I, shown here, into a lower position II, also shown.
  • the roller 1 is mounted and arranged in such a way that when the blank 6 is lowered, it presses its wall 6.2 inwards. Two adjacent rollers 1 each form a tooth that runs 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 firmly connected to a sleeve 10, for example by screwing.
  • the stamp 9 is located within the blank 6. It is itself designed like a gear.
  • the teeth of the stamp 9 work together with the rollers 1 during the burnishing process, in that one tooth of the stamp 9 engages between two rollers 1 that are adjacent to one another.
  • an intermediate body 11 is provided. This is preferably designed as a wedge ring and encloses all the rollers 1 with the plurality of housings 3 and the blank 6 arranged in the center figure 2 apparent.
  • the intermediate body 11 can be divided into numerous individual bodies or can 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 figure 1 recognizes, this is located in a likewise annular and wedge-shaped receiving space 12. The further the wedge-shaped intermediate body 11 is driven into the receiving space 12, the deeper the peripheral edge of the individual roller 1 penetrates into the material of the blank 6 and the greater the tooth height .
  • rollers 1 Two adjacent rollers 1 are arranged in a housing 3, here in two parts.
  • a wedge segment 15 is located between two adjacent pairs of rollers 1. This is stationary and determines the orientation and position of the housing 3, and thus also of the rollers 1.
  • the boiler house 4 with the housings 3 and rollers 1 arranged therein is stationary.
  • the preform 6 performs the already mentioned translational movement in the feed direction 7, here from top to bottom, optionally also from bottom to top.
  • the blank 6 takes the rollers 1 with it by means of frictional engagement and thus causes them to rotate.
  • the rollers 1 therefore do not need their own drive.
  • the position of the intermediate body 11 in the feed direction 7 is defined by interchangeable positioning rings 14.
  • the positioning rings 14 can be designed as rings that are closed over the circumference. However, they can also be formed by a multiplicity of individual ring segments positioned at a distance from one another or adjacent to one another.
  • non-annular spacers can also be used instead of the positioning rings 14.
  • the spacers, here the positioning rings 14, define the penetration depth of the disc-shaped rollers 1 into the material of the blank 6 with the position of the intermediate body 11 in the feed direction 7 at the same time. The penetration depth can thus be changed by inserting positioning rings 14 of a thickness (height) designed accordingly.
  • the wedge-shaped intermediate body 11 penetrates deeper into the tapering receiving space 12 and pushes the housing 3 resting against it and thus the roller 1 via the bearing journal 2 comparatively further in the direction of the blank 6. If, on the other hand, a comparatively thicker positioning ring 14 is inserted here (in the drawing below in the receiving space 12), the intermediate body 11 in Shifted towards the further section of the receiving space 12, so that the housing 3 with the roller 1 can press further in the direction of the supporting fixed environment, here the boiler house 4, and the roller 1 dips less into the wall 6.2 of the blank 6.
  • the bearing journals 2 have a special shape, which can also be designed independently of the features further described in this exemplary embodiment.
  • the bearing journals 2, each of which carries a roller 1, here a pair of rollers 1 are provided with a flattening 13 on their axial sections which protrude beyond the rollers 1 and are inserted into the housing 3 or the housings 3.
  • This flattening 13 is in the figures 1 , 2 and 3 evident.
  • the flats 13 are provided on the peripheral portion of the bearing journals 2 positioned towards the fixed environment on which the housings 3 are supported via the intermediate body or bodies 11 .
  • a flattening 13 can, for example, as shown in FIG figure 2 as can be seen, transition into the round, in particular circular, peripheral region of the bearing journal 2 via a bevel or a chamfer in the circumferential direction.
  • the counter-contour in the housing 3 does not have to be designed identically; for example, a round or rounded transition in the circumferential direction from the area of the flattening to the round or circular circumferential section is possible there.
  • the bearing journals which are essentially cylindrical with the exception of the flat areas 13, are provided with beveled end faces, see bevel 16.
  • the two end bevels 16 of a bearing journal 2 run towards one another in the direction of the blank 6.
  • the bearing journals 2 can be positioned closer to one another in the manner of a polygon over the circumference of the blank 6 .
  • the housing 3 accommodating the bearing journals 2 has a corresponding bevel 17 on the sides facing away from the rollers 1 it carries, which in particular ends flush with the bevel 16 of the bearing journals 2 and/or is positioned plane-parallel thereto.
  • the housings 3 also have a flat contact surface on their outer side facing the intermediate body 11, in contrast to an annular contact surface. This also leads to a more favorable surface pressure.
  • the one or more intermediate bodies 11 accordingly have flat contact surfaces on their inner circumference, which faces the blank 6, and form, as can be seen from FIG figure 3 is particularly clearly visible, a polygon on its inner circumference.
  • the outer circumference of the intermediate body or bodies 11 can be annular, although 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 pins 2, so no support rollers or the like are provided or support areas on the outer circumference of the rollers 1. It is therefore particularly easy to use a roller 1 with a first outer contour, which forms a first type of toothing. to be replaced by another roller 1 with a different contour for a different type of toothing. In the present case it is also easily possible due to the design of the housing 3 to remove it together with the rollers 1 from the areas between the wedge segments 15 .
  • two housings 3 or housing parts are always angular, in particular L-shaped, and form a U-shape when assembled, in which a roller 1 or, in this case, a pair of rollers 1 is accommodated. At the outer end, the legs of the L-shaped housing parts abut one another and at the inner end, the distance is defined and secured by the bearing pins 2 used.
  • a lubricating oil groove 18 can be introduced, which here in the figure 2 can be seen and is present on top of the bearing pin 2 is carried out.
  • rollers 1 shown here, with two sets 1 being inserted adjacent to one another in a housing 3 formed from two parts or in two adjacent housings 3, offers the advantage that rollers 1 that are comparatively small in diameter are used can without the risk of a collision of the components supporting them over the circumference of the blank 6 looming. A particularly compact embodiment can thus be created.
  • two spacers are provided, preferably in the form of positioning rings 14 or two groups of spacers or positioning ring segments, namely a spacer or a first group below the intermediate body or bodies 11 and a second spacer or a second group above the one or the Intermediate bodies 11.
  • These two spacers or groups of spacers together form a constant height, so that an exchange of the intermediate body or bodies 11 for setting different penetration depths of the rollers 1 into the blank 6 is not necessary. If the intermediate body or bodies 11 were to be fastened in another way, however, 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 large number of spacers are used over the circumference of an intermediate body 11 or a large number of intermediate bodies 11 are used over the circumference of the blank 6 .
  • the other two main ideas are also very interesting in practice. This allows the dimension of the intermediate body (or a plurality of intermediate bodies) 11 to be changed in the pressing direction of the rollers 1 . In the case of the second main idea, this happens by means of hydrostatic pressure.
  • Intermediate body 11 can namely 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 dimensions of intermediate body 11 in the pressing direction.
  • the contact pressure that acts on the bearing pin 2 and thus on the penetration depth of the roller 1 into the wall 6.2 of the blank 6 is generated by tempering, preferably by means of electrical resistance heating. Whether you use an intermediate body or another element that is responsible for the contact pressure is a secondary question.
  • the invention can be used not only in the production of spur gears, but also in helical gears. It does not even have to be gear wheels, but any gearing can be considered for the application of the invention, even on non-rotating components.
