Definitions

  • the invention relates to a method for producing a dressing tool for a grinding tool, preferably for a grinding worm, according to the preamble of claim 1.
  • a dressable multi-start grinding worm is generally used when machining gears, in particular, with rolling tools.
  • the grinding worm is dressed with a single or multi-groove dressing roller.
  • the present invention relates to a method for producing such a dressing tool.
  • Multi-groove full profile rollers are preferably provided here, which can be used for the efficient dressing of grinding worms.
  • a method of the type mentioned is from CH 684 249 A5 known.
  • a solid steel tool core is used as a support element.
  • Another solution is in the DE 101 56 661 A1 described.
  • a similar process is disclosed in JP H04 244 377 A .
  • Other solutions show that US 2002/0182401 A1 that US 2014/0273773 A1 that US 2014/0302757 A1 that WO 2007/000831 A1 and the US 6 200 360 B1 .
  • a shaped ring is produced by another method, which is provided with the workpiece-specific profile.
  • a diamond or nickel layer is usually deposited on this profile in a galvanic process, which - glued to a core - ultimately results in the dressing tool mentioned at the beginning after various other process steps.
  • the manufacturing process is very complex. Often, the form ring is already in a galvanic bath for up to three weeks for the production of the diamond or nickel layer.
  • the profile of the dressing tool generated in this way sometimes has errors that can be traced back to various causes. Specifically, the outer flanks of the profile "fold out", which is attributed to tensions in the structure. Furthermore, thermal stresses are also noticeable, which lead to errors in the profile.
  • the invention is therefore based on the object of developing a generic method in such a way that the profile of the dressing tool produced corresponds as closely as possible to the ideal contour; this is to eliminate profile errors on the dressing tool.
  • the deformation of the nickel layer remains as small as possible. Accordingly, the dressing tool should have the most precise possible geometry.
  • the solution to this problem by the invention provides a method in which the invention provides that an open lattice structure with openings is used as the support element, so that the radially inner surface is not closed radially by the support element.
  • the support element preferably extends over a width that corresponds to between 90% and 100% of the width of the dressing tool.
  • a structure is preferably used as the support element which has a number of rings which run in the circumferential direction of the radially inner surface, the rings being connected to one another by means of cross struts, the cross struts running in the axial direction of the dressing tool.
  • the rings and / or the cross struts are preferably made of metal.
  • the rings and / or the cross struts preferably have a circular cross section. In this respect, a wire with a circular cross section can be used as the base material for the production of the support element.
  • the number of rings preferably results from the number of projections plus one. In this case there is a ring on both sides of each recess of the shaped ring.
  • the rings and the cross struts can be cohesively connected to one another before they are used or before they are introduced into the shaped ring; this is particularly thought of welding or soldering.
  • the form ring can rotate at least temporarily around its axis while performing step c) above. This can cause the abrasive material (in particular the diamond powder) to be held in the recesses of the shaped ring by the centrifugal force until it is fixed to the surface of the recess by the (in particular galvanic) coating process.
  • abrasive material in particular the diamond powder
  • the removal of the shaped ring according to step d) above is preferably carried out by machining, in particular by turning off, the shaped ring.
  • One aspect of the present invention thus consists in introducing a strut (i.e. the support element) into the nickel layer that forms during the preferably galvanically carried out coating process.
  • This strut counteracts and prevents possible deformation.
  • a galvanic coating electrochemical deposition; "galvanic nickel”
  • a chemical coating can also be provided (“chemical nickel”).
  • Various coating materials are of course also possible, nickel being preferred.
  • the material of the support element is chosen so that it can be easily inserted into the nickel layer and deforms as little as possible. Care is taken to ensure that the deposited galvanic layer cannot deform.
  • the support element is galvanically connected to the galvanic layer, which may already have been applied beforehand (as part of a first fixation of the abrasive material in the molded ring) and which already contains the abrasive body.
  • the design of the support element is selected so that it counteracts any deformation stress that may be acting.
  • the support element is designed or designed in such a way that a uniform deposition of the galvanic layer can also be achieved after the support element has been introduced.
  • the support element may not form a shield; the exchange of the electrolyte must be guaranteed.
  • the support element can be introduced before or after diamond coating (i.e. before or after the abrasive material is introduced onto the surface of the above-mentioned recesses).
  • the proposed configuration of the support element ensures that the support element does not cause any change in the grain density (number of grains on the surface) and no grain defects during electroplating.
  • the proposed invention is used in particular in the case of solid profile rolls or in the case of galvanic negative coating.
  • a dressing tool 1 is shown in the form of a dressing roller.
  • the dressing tool 1 consists of a rotationally symmetrical component which has an axial direction a and a radial direction r.
  • the dressing tool 1 has a width B in the axial direction.
  • the dressing tool 1 has three annular projections 2 which run in the circumferential direction and extend in the radial direction r. These projections 2 are provided with abrasive material 6 in the form of diamond powder (corresponding grain size; depending on the grinding tool to be dressed), so that a grinding worm can be dressed with the dressing tool 1. This method is known as such and need not be explained in more detail here.
  • FIG. 2 The manufacture of such a dressing tool 1 is shown in Figure 2 illustrated.
  • the central element for the production is a shaped ring 3, which has an essentially hollow cylindrical shape.
  • recesses 5 are machined (ie ground in with high accuracy), which are congruent with the projections 2 (negative method).
  • the abrasive material 6 (diamond powder) is first placed in the recesses 5 during the manufacture of the dressing tool 1, so that the surface 8 of the recesses 5 is at least partially covered or covered with this abrasive material 6.
  • a galvanic coating 7 is then produced, so that the abrasive material 6 is fixed on the surface 8 of the recess 5 and is available for the later dressing process.
  • Figure 2 a state can be seen in which the galvanic coating process has already largely been completed, ie the area of the recesses 5 has already been filled with the material of the coating and, moreover, has detected a region which extends radially inwards.
  • a support element 9 was introduced into the mold ring 3, which was at least partially integrated into the dressing tool 1 that was formed by the galvanic coating process.
  • Figure 2 it can be seen that the support element 9 has been completely integrated into the coating material, ie is surrounded by it. Thus, the support element is integrally connected to the dressing tool 1 being produced. However, it is also possible that the support element 9 is not completely surrounded by the coating material after the coating process has been completed.
  • the mold ring 3 is removed, which can be done by a machining operation.
  • the dressing tool 1 is thus available for its intended use.
  • the supporting elements 9 used can be seen again in a perspective view. It can be seen here that the support element 9 has a width b which essentially corresponds to the width of the dressing tool 1 or is slightly smaller than said width B.
  • the support element 9 consists of several (in the exemplary embodiment: four) rings 11 which are connected to one another (in particular: soldered) by cross struts 12 which are arranged equidistantly around the circumference. 20 to 80 cross struts 12 are preferred over the circumference. So what results in Figure 3 can be seen, openings 10, which make it possible for electrolyte to pass through the support element 9 during the coating process and thus the plating process is not or hardly hindered by the support element 9.
  • the support element 9 (or support grid) is designed as a grid-shaped structure made of longitudinal and transverse struts, which is clamped into the molded ring.
  • the dimensions of the grid structure are adapted to the contour to be supported.
  • the support element is positioned in the form ring in such a way that the total width of the grooves (recesses) is covered and the support element is completely embedded in the nickel layer.
  • the coating process which is usually carried out as a galvanic process, advantageously takes place in two stages: In a first stage, the abrasive material 6 located in the recesses 5 is fixed in a first work station by a first coating with nickel, the molding ring 3 rotating, so that the abrasive material 6 is held in the region of the surface 8 of the recess 5 by the centrifugal force .
  • the coating 7 can finally be carried out in a second work station to the extent desired. Before this takes place, however, the support element 9 is introduced into the mold ring 3 and integrally bonded through the coating process.
