Definitions

  • the invention relates to a cold rolling machine and a method for producing a profile on a workpiece using the cold rolling machine.
  • a cold rolling machine according to the preamble of claim 1 and a method for producing a profile by means of a cold rolling machine are disclosed, for example EP 1 286 794 B1 famous.
  • Cold rolling involves deforming at least a portion of a workpiece and thereby creating a profile in the workpiece that extends circumferentially around the workpiece.
  • the profile can, for example, be straight teeth.
  • the profile can be used to provide a non-rotatable connection between the workpiece, such as a shaft, and another component, such as a gear. This non-rotatable connection must be able to withstand the loads occurring during operation. For this reason, the workpiece is usually hardened.
  • hardening is only possible after the profile has been created by cold rolling. With some workpieces, this means that the profile produced during cold rolling does not have the desired dimensions after hardening. In particular, a conical deformation or a conical distortion of the profile produced can occur as a result of the hardening.
  • It can be the object of the present invention are considered to provide a cold rolling machine and a method for producing a profile, by means of which a profile can be produced which, after hardening, meets the dimensional requirements.
  • the cold rolling machine has a machine frame and two tool units. Each tool unit is arranged on the machine frame and the two tool units are preferably constructed in the same way. Each tool unit has at least one roller bar, which extends along a longitudinal direction, and has a roller bar profile. The rolling rod profiles of the rolling rods of the different tool units face each other. Each roller bar is attached to a tool carriage. The tool carriage is mounted so that it can move linearly in the longitudinal direction by means of a carriage bearing device. A slide drive device is set up to move the tool slide in the longitudinal direction.
  • each tool unit has a pivoting support.
  • the swivel support is mounted on the machine frame so that it can swivel about a swivel axis by means of a swivel bearing device.
  • the pivot axis extends in the longitudinal direction.
  • the carriage bearing device is arranged on the swivel support, on which the tool carriage is supported, which in turn carries the rolling rod.
  • the swivel support can be swiveled about the swivel axis by means of a swivel drive of the tool unit.
  • the rolling rod is also pivoted about the pivot axis together with the pivot carrier. By pivoting about the respective pivot axis, an angle of inclination in a plane perpendicular to the longitudinal direction can be set between the roller rod profiles of the roller rods of the two tool units. If the absolute value of this angle of inclination is not equal to zero, a profile is produced in the workpiece which has a conicity corresponding to the angle of inclination.
  • the angle of inclination in the cold rolling machine can be set such that it at least partially compensates for a conical distortion caused by the subsequent hardening of the workpiece, so that the workpiece has a conicity after hardening that lies within a predetermined tolerance range.
  • a process-related conicity of the profile can thus be compensated with the invention in order to obtain a cylindrical profile.
  • a conicity can result from hardening and/or e.g. if the axial material flow at the ends of the profile is not symmetrical and/or from different process forces.
  • defined conical profiles can also be generated, independently of the further processing of the workpiece.
  • the cold rolling machine has a control device for controlling the swivel drives of the tool units.
  • the control device can be set up to pivot the pivot supports in each case by the same pivot angle amount about the respective pivot axis. This creates a symmetrical alignment of the two tool units relative to a reference plane that is along the longitudinal axis of the workpiece the manufacture of the profile and parallel to the longitudinal direction.
  • each swivel drive has a first wedge body with a first inclined surface that is inclined relative to a longitudinal direction.
  • the pivot carrier of the respective tool unit can be supported at a support point on this first inclined surface.
  • the support point is arranged at a distance radially from the pivot axis.
  • the first wedge body is mounted such that it can be moved or displaced in the longitudinal direction and, in particular, can be displaced linearly.
  • the displacement of the first wedge body changes the position of the support point along the first inclined surface, causing a pivoting movement of the pivoting support.
  • the wedge angle of the first inclined surface relative to the longitudinal direction is less than 5 degrees or less than 3 degrees. In one embodiment, the wedge angle of the first bevel is about 2 degrees.
  • a pivot support can be moved about the pivot axis by a pivot angle of a maximum of 2.0 degrees or a maximum of 1.0 degrees and preferably a maximum of 0.2 degrees.
  • each swivel drive has a second wedge body with a second inclined surface that is inclined relative to the longitudinal direction.
  • the second wedge body is arranged or fastened to the pivoting support.
  • the second bevel is adjacent to the first inclined surface flat. This allows the surface load to be reduced.
  • the first wedge body is arranged on a rotatably mounted shaft.
  • the shaft can be mounted on the machine frame so that it can move linearly in the longitudinal direction.
  • the swivel drive can have a screw drive, by means of which the shaft can be moved in the longitudinal direction.
  • pivoting support has an L-shape in a plane perpendicular to the longitudinal direction.
  • a bearing body is movably mounted in a vertical direction on the pivot support.
  • the height direction is perpendicular to the longitudinal direction and perpendicular to the transverse direction.
  • the tool carriage can be movably arranged on the bearing body.
  • the carriage drive device can be mounted on the pivot support so that it can move in the vertical direction together with the bearing body. This results in an assembly comprising the rolling rod, the tool carriage and the carriage drive device, which is arranged on the pivoting support such that it can be moved in the vertical direction.
  • the pivot carrier and this assembly are in turn mounted pivotably about the pivot axis.
  • the setting drive can, in one embodiment have a third wedge body with a third oblique surface inclined relative to the longitudinal direction.
  • the third wedge body is preferably movably mounted on the pivot support.
  • the bearing body is supported directly or indirectly on the third wedge body or the third inclined surface.
  • a fourth wedge body can be arranged or attached to the bearing body.
  • the fourth wedge body has a fourth oblique surface inclined with respect to the longitudinal direction.
  • the fourth sloping surface can lie flat against the third sloping surface.
  • the carriage drive device has a drivable pinion.
  • the pinion gear may be drivingly connected to a carriage drive motor.
  • the pinion is in engagement with a rack.
  • the toothed rack extends in the longitudinal direction and is arranged or attached to the tool carriage. When the pinion rotates, the toothed rack moves in the longitudinal direction together with the tool slide.
  • any embodiment of the cold rolling machine described above may be used to create a profile on a portion of the workpiece to be profiled.
  • an angle of inclination between the roller rod profiles is first set in the plane at right angles to the longitudinal direction.
  • the section of the workpiece to be profiled is then arranged between the rolling rods or the rolling rod profiles.
  • the roller bars are moved in opposite directions in the longitudinal direction.
  • the rolled rod profiles engage in the section of the workpiece to be profiled and reshape it to create the desired profile.
  • the workpiece rotates around its longitudinal axis and, so to speak, rolls on the roller bar profiles.
  • At least the profiled section of the workpiece can then be hardened.
  • a conicity of the profile produced is preferably measured immediately after the profile is produced and/or after hardening and is compared with a tolerance range. Even if the profile must have a defined conicity directly after cold rolling - a defined conicity can also be a cylindrical profile, i.e. a conicity equal to zero - the profile produced can be measured unhardened and compared with a tolerance range. If the conicity determined is within the tolerance range immediately after the profile production and/or after hardening, the cold rolling machine or the angle of inclination is set correctly and further workpieces can be produced.
  • a change in the angle of inclination is determined based on the deviation and the angle of inclination is changed by the change in the angle of inclination determined.
  • the others Workpieces of the same type can be manufactured with this setting without increased rejects due to conicity distortion during hardening.
