  • the present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 7, (see eg US-A-4,307,592 ).
  • impact rolling machines are conventionally used.
  • the movements of the tools i. the working movement, direction and delivery of Profiltechniksrollen resp. rollers, and the movement of the workpiece, i. the axial feed to the tools as well as the rotation of the workpiece, coordinated with each other geometrically determined to achieve the desired profiling in the appropriate dimensions and accuracies.
  • the working movement and feed movement of both the tools as well as the workpiece can be done continuously, which can be realized by coupling these movements by means of mechanical or electronic transmission.
  • the workpiece should ideally be discontinuous resp. be rotated intermittently.
  • Such a movement can be mechanically, for example by means of a gear construction based on the Realize Malter Heilgetriebes.
  • a transmission allows the generation of discontinuous rotational movements starting from a continuously rotating drive machine.
  • the respective rotational steps or graduation steps are dependent on the geometry of the transmission and its translation. This means that the division steps to be achieved must be defined and, based on this, the gearbox must be designed and built accordingly.
  • such a transmission and thus the production plant is limited to a specific, predetermined number of workpiece teeth.
  • the object of the present invention was to find such a device, which allows easy adjustment of the pitching steps in the rotation of workpieces, in particular for workpieces for processing with impact rolling machines.
  • the device for producing cylindrical workpieces which have a defined profiling, with an axially displaceable and intermittently rotatable about the longitudinal axis Workpiece holder and periodically acting on the workpiece forming tools, at least one separate from the drive of the forming tools separate drive for the intermittent rotation of the workpiece holder on.
  • This separate drive is connected to an electronic control, which controls the intermittent rotation in response to the drive of the forming tools.
  • This can advantageously be the rotational position of the workpiece as desired depending on the respective movement resp. Set the position of the forming tools and thus produce a precise profile geometry over the entire length of the profile of the workpiece. Both the position and the duration of the workpiece standstill during the Umformwerkmaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschine
  • the forming tools are profiled rollers or rollers, which are driven continuously circulating on a circular path, wherein the circular path is arranged parallel or obliquely with respect to the longitudinal axis of the workpiece, preferably adjustable, extending.
  • the electronic control of the intermittent rotation of the workpiece has proved to be particularly advantageous.
  • the workpiece holder is mounted in a parallel to the workpiece axis guided and displaceable headstock and connected via an at least axially elastic coupling with the drive.
  • the drive is advantageously free of the forces acting on the workpiece forces of the forming tools and despite the high forming forces exact positioning resp. guarantee intermittent rotation.
  • the drive is arranged in a likewise guided parallel to the workpiece axis and displaceable secondary headstock.
  • the secondary headstock can be arranged either in the same guide as the headstock of the workpiece holder, or in a separate, arranged parallel thereto guide.
  • This will be achieved a very large variation of the movements and allows the production of complicated profile geometries.
  • such a device is also suitable for the generation of obliquely extending with respect to the longitudinal axis profilings. Gearing.
  • the workpieces are cylindrical solid or hollow body.
  • the inventive device is advantageously suitable both for the processing of solid bodies as well as for the processing of hollow bodies.
  • hollow bodies both external and internal profiles can be resp. -veriereitch be generated.
  • the hollow workpieces are applied to a cylindrical mandrel, which preferably has a profiled, preferably longitudinally profiled, surface.
  • the method for producing cylindrical workpieces with a defined profiling with an axially displaceable work fixture for the workpieces and intermittently rotatable about the longitudinal axis, and forming tools acting periodically on the work piece, is characterized in that the work piece is moved about its longitudinal axis by means of an electronic control system with one of the forming tools separate drive rotates resp. is stopped. This happens according to the invention as a function of the movement of the forming tools and thus to produce a certain defined profiling geometry.
  • control imposes on the workpiece both a left and right turn as well as a standstill.
  • desired profiling geometry can be generated very accurately according to the geometry and movement of the forming tools.
  • the controller also controls the drive and the feed movement of the forming tools according to specifications, as well as the axial feed movement of the workpiece.
  • the gearboxes do not have to be readjusted in a labor-intensive manner due to different division numbers for different workpieces, for example. be rebuilt.
  • the invention further claims the use of a device according to the invention and / or application of the method according to the invention for producing helical gears on cylindrical workpieces.
  • FIG. 1 shows the longitudinal section through a conventional impact rolling machine for machining cylindrical workpieces.
  • the workpiece 1 is seated on a workpiece holder 2, which can be fed along its axis z into the processing area 3.
  • the delivery takes place for example via its own drive 4, which drives a spindle 6 via a gear 5.
  • the forming tools 9, which are driven by the drive 8, are mechanically connected directly to the workpiece holder 2 via a maltese-cross-type transmission 7.
  • the intermittent rotation about the axis Z of the workpiece holder 2 with the movement of the forming tools 9 is directly coupled according to the interpretation of the translation and the maltesernchartigen gear 7, respectively. synchronized. Due to this design, a defined profile can now be incorporated into the surface of the workpiece 1 by the forming tools 9.
  • FIG. 2 is now shown schematically the longitudinal section through an inventive device.
  • the structure and drive of the processing area 3 corresponds to the known structure, as in FIG. 1 is shown.
  • the drive 8 is advantageously connected via a mechanical transmission 10 with the forming tools 9.
  • the workpiece holder 2 with the workpiece 1 now has its own drive 11.
  • the delivery of the workpiece 1 is again advantageously via a separate drive 4 with gear 5 and spindle 6, wherein the drive 11 together with the workpiece 1, respectively. the workpiece holder 2 is delivered.
  • both the drive 8 and the drive 11 advantageously have corresponding position sensors.
  • the big advantage of the electronic synchronization is on the one hand that the control accordingly
  • the specifications for the profile division can each be set individually quickly and easily without having to intervene in the impact rolling machine.
  • Programming tools provided a particularly simple setting resp. Programming the control of the machine, eliminating the need for manual adjustment.
  • FIG. 3 is still schematically the front view of a workpiece 1 shown with engaged machining tool in the form of a profile roller 12.
  • the profile roller 12 is shown here in its current maximum penetration depth into the surface of the workpiece 1.
  • a profiling of the workpiece surface is achieved, in each case at a distance t, which is referred to as profile division.
  • this area is now still shown in longitudinal section, from which it can be seen that the profile roller 12 is guided on a circular path, wherein the circle 13 represents the trajectory of the outer regions of the profile roller 12.
  • the profile roller is shown on the one hand in the exit position 12 ', where it just leaves the surface of the workpiece 1, and in the preliminary work position 12 ", where the forming work on the workpiece 1 is started, and the profiled roller enters the area of the profile just formed during the following revolution of the profile roller 12, it has to be rotated around its circular path about the profile pitch t in order to achieve a profiling around the entire circumference, this standstill phase can be achieved according to the invention precisely by the separate drive and electronic synchronization and the number of teeth to be generated, in particular be easily adjusted in relation to the position and duration of the workpiece standstill.
  • a helical toothing can be realized by means of the impact rolling tools.
  • inventive embodiment with electronically coupled drive also allows the use of the same machine for spin forming with spinning rollers, not an intermittent rotation of the workpiece is necessary, but this must be driven in rotation with a certain, usually very high constant speed. This eliminates the need for conventional switching devices of the mechanical transmission, as these can also be easily set and performed electronically by the controller.
  • This flow-forming process makes it possible to preform in the same operation first on a spinning mandrel from a disc a thin-walled hollow part and then to interlock this on the same spinning mandrel.
