Description
- 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. During such a forming process performed by means of the known forming tools 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. In order to counteract these axial forces, 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.
- It is the object of the present invention to further develop a forming tool of the afore-mentioned kind, so that by means of the inventive forming tool a reduction of the axial forces is achieved.
- This object is solved by the invention in that in the surface of the forming element being inclined with the first angle of inclination 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.
- By 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. By this it is achieved that, when radial forming forces act upon the work piece, the declining faces of the recesses assimilate the axial force component, so that the axial forces acting upon the forming machine in the feeding direction and being generated by the working process are reduced.
- An advantageous further development of the invention provides that 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. These measures got the advantage that such an arrangement of the recesses of the inventive surface structure provides that only a very small torsion load acts upon the work piece, which is created when the forming tool rotates during the forming process around the stationary work piece. The recess being arranged orthogonally to the longitudinal direction and hence in the feed direction of the work piece therefore results in an advantageous way not only in small axial forces, but yields that the forming tool only impacts no or only a small torsion force on the work piece.
- 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. But 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.
- Further advantageous developments of the invention are the subject matter of the dependent claims.
- Further details and advantages of the invention are given in the exemplary embodiment, which is described by means of the figures. They show:
-
FIG. 1 : a front view of the exemplary embodiment, -
FIG. 2 : a longitudinal section through the forming tool ofFIG. 1 along the line II-II, -
FIG. 3 : a schematical representation of the surface structure, and -
FIG. 4 : a schematical representation of a tool head of a swaging machine with a forming tool according toFIGS. 1 to 3 . - Before in details the exemplary embodiment of a forming tool generally designated with 12 is described, for the sake of an easier understanding the basic actions occurring in a forming process carried out by means of such an forming tool are described:
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 aswaging axle 2 and—in the case described—four swaging modules being radially slightable. Each swaging module has got aswaging plunger 10, having at its radially outer end aroller path 4, which is acted upon periodically bypressure rollers 6 being contained in aroller cage 5, in that theswaging axle 2 and/or theroller cage 5 is driven by anouter ring 7. Thepressure rollers 6 hereby are supported by theouter ring 7. The swaging modules contain besides the swaging plunger 10 furthermore anadjustment plate 11 and the formingtool 12. Such aswaging head 1 is generally known and therefore it is not necessary to describe it further in details. - In order to produce from a tube- or rod-like initial work piece an end product, which has got in a first section still the non-reduced initial diameter of the initial work piece, which has got in a second section a diameter being reduced due to the forming process, and which has a transition section between the first and second section, in which the outer diameter of the work piece increases continuously from the reduced diameter to the initial diameter, so that in the final work piece the axially inclining transition section is formed, it is provided that the forming
tool 12 has got—as it can be seen from FIG. 2—a formingelement 21 being provided in abase body 12′ of the formingtool 12, which is arranged under a defined first angle of inclination α1 to the central axis M of the formingtool 12 and hence to the feed direction of the work piece. Such a formingtool 12 is known and therefore there is no need to describe it further. For the sake of an easier understanding only it has got to be explained that the radial forming force, which is generated by the forming tool, creates, due to the angled arrangement of the formingelements 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. - In order to better compensate these axial forces and to reduce the axial load of the work piece, which can lead to cripplings and bulgings, as well as the one of the feeding device, the described forming
tool 12 now provides that in asurface 21′ of the forming element 21 a—in relation to thesurface 21—recessed surface structure 22 is provided, which has got (seeFIG. 2 ) at least onerecess 23 and usually a plurality ofrecesses 23. The detailed formation of thesurface structure 22 is now described by means ofFIG. 3 , in which an exemplary embodiment thereof is shown. But it must be stressed that the angles, radii and further dimensions as well as thesurface 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 thesurface structure 22 shown inFIG. 2 . One can see thesurface 21′ of the formingelement 21 of the formingtool 12 and further, that thesurface structure 22 is not—as it is the case of the forming tool explained at the beginning —provided on thesurface 21′, and is therefore not elevated. Contrary to that, it is provided that therecesses 23 are arranged in thesurface 21′ of the formingelement 21. In the exemplary embodiment described, the inclination of intake slope S of the formingelement 21, namely the first angle of inclination, is α1 =10°, in relation to the central axis M of the tool. Each of therecesses 23 has got adeclining face 23 a and aninclining face 23 b, wherein—as shown in FIG. 4—thedeclining face 23 a of therecess 23 is provided under a second angle of inclination of (in this case:) α2=29° in respect to the intake slope S. The inclination of thefaces 23 a therefore has got a value of α2−α1 in respect to the central axis M. The inclination of thedeclining faces 23 a ofrecesses 23 is oppositely orientated to the first angle of inclination α1 defining the slope of the formingelement 21 and the absolute value of the second angle of inclination α2 is here larger than the one of the first angle of inclination α1 of the formingtool 12. The opposite orientation of the inclinations of the formingelement 21 and thedeclining faces 23 a of therecesses 23 brings forth that the axial forces, which are generated by the swaging modules, are at least partially assimilated by the formingtool 12 and therefore do not act upon the work piece and/or the feeding device of the forming machine, since these axial forces are assimilated by thefaces 23 a being arranged oppositely to the inclination of the formingelement 21. The decliningfaces 23 a of therecesses 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 therecesses 23 recede in these recesses, so that thedeclining faces 23 a of therecesses 23 act upon the work piece in the feed direction. - It is evident for the person skilled in the art that the afore-mentioned exemplary values of the first angle of inclination of α1=10° and of the second angle of inclination α2=29° only have got an exemplary character. Important is only that the
faces 23 a are inclined in relation to the intake face S, so that the absolute value of the second angle of inclination α2 is equal to the absolute value of the first angle of inclination α1. - It must be noted in this context that the wave-like shape of the
surface structure 22 is not compulsory. It is possible too to form therecesses 23 saw tooth-like, wherein the straightly decliningface 23 a of such a saw tooth at least partially assimilates the axial forces. - As it can be seen from
FIG. 4 , thesurface structure 22 has got at least one, but in practice a plurality ofrecesses 23, which are preferably arranged parallel or essentially parallel to each other and—once again preferably—essentially orthogonal to the longitudinal direction of the formingtool 12 and in this way to the feeding direction V of the work piece. But it is possible too that at least one of therecesses 23 is not—as shown in the figures—provided orthogonal to the longitudinal direction of the formingtool 12, but it is arranged in a defined angle thereto. - Concludingly, it must be stated that the described design of the forming
tool 12 with arecessed surface structure 22 in combination with the described formation of therecesses 23 and in particular with the one of the declined faces 23 a, a formingtool 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.
