Definitions

  • the invention relates to a forming tool, in particular a swaging tool, which has a base body, in which at least one forming element is provided, which is inclined at a first angle of inclination to a central axis of the forming tool, thereby determining an intake slope of the forming tool.
  • Such a forming tool is known from DE 103 28 052 B4 of the applicant and is used for the forming, in particular for the swaging, of work pieces in a swaging machine.
  • substantial axial forces acting upon the work piece are created, which is true for a feed swaging process as well as for a recess swaging process. These forces can result in a disadvantageous manner in damage symptoms on the work piece, which appear in form of bulgings or cripplings.
  • the axial force created by the forming tools furthermore puts stress on the forming machine as well as on the feed system for the work piece and on the clamping device holding the workpiece, since the afore-mentioned units have got to compensate the axial forces generated by the forming process.
  • DE 103 28 052 B4 discloses that on the surface of the forming element of the forming tool an elevated, relief-like and wave-like surface structure is provided, which has got a plurality of elevations. Via these elevated surface structure on the surface of the forming element a forming tool is created, which has got the advantage that the areas of the work pieces acted upon with this forming tool have got a high surface quality. A further reduction of the stress created by the axial forces during the forming process is still desired.
  • a recessed surface structure is formed, having at least one recess with a declining face, and that the declining face of this recess has got, in relation to the intake slope of the forming element, a second angle of inclination, which is orientated in an opposite direction with regard to the first angle of inclination and the absolute value thereof is larger than or equal to the absolute value of the first angle of inclination.
  • the inventive measures it is achieved in an advantageous way that in the surface of the forming element at least one, preferably a plurality of recesses are provided, the declining face of which is declined larger than the one of the forming element and is oppositely orientated to its declination.
  • At least one recess, preferably all recesses of the surface structure being provided in the surface of the forming element are arranged orthogonally or essentially orthogonal to its longitudinal direction.
  • a further advantageous development of the invention provides that at least two recesses of the surface structure of the forming element of the inventive forming tool run parallel or at least essentially parallel to each other. Such a measure has got advantages in relation to a small torsion load of the work piece acted upon by the inventive forming tool, and in particular, if, according to a further advantageous development of the invention, it is provided that at least two recesses of the surface structure of at least one forming element run essentially straight.
  • a further advantageous development of the invention provides that at least two recesses of the surface structure of the inventive forming tool are arranged inclinedly to the longitudinal direction of the forming element.
  • Such a measure results in that higher torsion load act upon the work piece as it would be in the case of recesses being arranged orthogonal to the longitudinal direction of the forming element and hence to the feed direction of the work piece.
  • the angled arrangement of the recesses of the surface structure has got the advantage that in the case of work pieces, for which a torsion load does not appear to be disturbing, a further reduction of the axial forces acting upon the feeding device and hence opposite to the feeding direction of the forming machine is achieved.
  • FIG. 1 a front view of the exemplary embodiment
  • FIG. 2 a longitudinal section through the forming tool of FIG. 1 along the line II-II,
  • FIG. 3 a schematical representation of the surface structure
  • FIG. 4 a schematical representation of a tool head of a swaging machine with a forming tool according to FIGS. 1 to 3 .
  • FIG. 4 shows a swaging head generally designated with 1 of a swaging machine, this means a tool head of a swaging machine, which has a swaging axle 2 and—in the case described—four swaging modules being radially slightable.
  • Each swaging module has got a swaging plunger 10 , having at its radially outer end a roller path 4 , which is acted upon periodically by pressure rollers 6 being contained in a roller cage 5 , in that the swaging axle 2 and/or the roller cage 5 is driven by an outer ring 7 .
  • the pressure rollers 6 hereby are supported by the outer ring 7 .
  • the swaging modules contain besides the swaging plunger 10 furthermore an adjustment plate 11 and the forming tool 12 .
  • Such a swaging head 1 is generally known and therefore it is not necessary to describe it further in details.
  • a forming element 21 being provided in a base body 12 ′ of the forming tool 12 , which is arranged under a defined first angle of inclination ⁇ 1 to the central axis M of the forming tool 12 and hence to the feed direction of the work piece.
  • a forming tool 12 is known and therefore there is no need to describe it further.
  • the radial forming force which is generated by the forming tool, creates, due to the angled arrangement of the forming elements 21 , a force acting in the axial direction of the work piece, which stresses the work piece and must be compensated by a feeding device (not shown) of the forming machine, by means of which the work piece is fed during the forming process.
  • the described forming tool 12 now provides that in a surface 21 ′ of the forming element 21 a —in relation to the surface 21 —recessed surface structure 22 is provided, which has got (see FIG. 2 ) at least one recess 23 and usually a plurality of recesses 23 .
  • the detailed formation of the surface structure 22 is now described by means of FIG. 3 , in which an exemplary embodiment thereof is shown. But it must be stressed that the angles, radii and further dimensions as well as the surface structure 22 shown there are only of exemplary nature and not to affect the generality of the following explanations:
  • FIG. 3 shows a cross section through the surface structure 22 shown in FIG. 2 .
  • the surface 21 ′ of the forming element 21 of the forming tool 12 shows the surface 21 ′ of the forming tool 12 and further, that the surface structure 22 is not—as it is the case of the forming tool explained at the beginning —provided on the surface 21 ′, and is therefore not elevated.
  • the recesses 23 are arranged in the surface 21 ′ of the forming element 21 .
  • the inclination of the faces 23 a therefore has got a value of ⁇ 2 ⁇ 1 in respect to the central axis M.
  • the inclination of the declining faces 23 a of recesses 23 is oppositely orientated to the first angle of inclination ⁇ 1 defining the slope of the forming element 21 and the absolute value of the second angle of inclination ⁇ 2 is here larger than the one of the first angle of inclination ⁇ 1 of the forming tool 12 .
  • the declining faces 23 a of the recesses 23 therefore form a kind of counter bearing for these axial forces and deviate them in the forming tool 12 :
  • the substance of the work piece of the areas being above the recesses 23 recede in these recesses, so that the declining faces 23 a of the recesses 23 act upon the work piece in the feed direction.
  • the wave-like shape of the surface structure 22 is not compulsory. It is possible too to form the recesses 23 saw tooth-like, wherein the straightly declining face 23 a of such a saw tooth at least partially assimilates the axial forces.
  • the surface structure 22 has got at least one, but in practice a plurality of recesses 23 , which are preferably arranged parallel or essentially parallel to each other and—once again preferably—essentially orthogonal to the longitudinal direction of the forming tool 12 and in this way to the feeding direction V of the work piece. But it is possible too that at least one of the recesses 23 is not—as shown in the figures—provided orthogonal to the longitudinal direction of the forming tool 12 , but it is arranged in a defined angle thereto.
  • a forming tool 12 is generated which excels in that a substantial reduction of the axial forces acting upon the work piece and/or the feed device of the forming machine is achievable.
