Definitions

  • the invention relates to a cold rolling machine according to the preamble of patent claim 1 and a method for cold rolling a workpiece.
  • the workpiece to be machined is rotatably tensioned between two tips or other quick-action clamping devices, this workpiece clamping device generally being associated with a feed axis.
  • the desired profiling of the workpiece via two synchronously counter-rotating rolling rods, which impinge simultaneously on the workpiece and this initially by frictional engagement and later by positive engagement in rotation.
  • the material is in the free spaces of the tool, d. H. displaced by the rolling rods.
  • the height of the ground profile of the rolling rod increases in the forming area, so that each tooth of the rolling rod is pressed slightly deeper into the workpiece, as the preceding.
  • This non-cutting cold forming of profiles is about thirty times faster than the machining of the profiles.
  • Cold rolled workpieces also offer higher strength, better surface finish and high accuracy.
  • transverse roll strips provided, which are arranged by linear drives in a direction transverse to the axis of rotation movable.
  • the transverse rolling strips are received by an upper support and sub-support, wherein the upper support in a vertical direction above and a sub-support in a vertical direction below the tool chuck are arranged movable.
  • the rolling rod For dimensional corrections on the workpiece, it may be necessary to deliver the rolling rod in the radial direction (relative to the workpiece) in order to form the predetermined tread depth. This delivery is done manually via adjusting screws, over which the radial position of the rolling rods is adjustable relative to the workpiece. For this readjustment of the rolling process must be interrupted, so that the productivity of the system is reduced.
  • the present invention seeks to provide a cold rolling machine and a method for cold rolling, through which the downtime during production are reduced.
  • the cold rolling machine is provided with a feed device with an integrated feed drive, via which the rolling rods can be adjusted during the rolling process in the direction of engagement. That is, each rolling rod is associated with a feed axis, which allows an adjustment of the rolling rods in approximately radial direction with respect to the workpiece to be machined.
  • this feed device thus the tread depth can be changed during the rolling process, so that, for example, the desired Endprofiliefe not - as required in the prior art - during a feed movement of the rolling rods, but during several Walzstangenh Claus can be formed, in which the rolling rods are readjusted in the radial direction. This makes it possible to minimize the length of the rolling rod, so that the dimensions of the cold rolling machine remain relatively low.
  • the rolling rods can be performed substantially with constant tread depth, so that their production is much easier than in the conventional rolling rods with increasing profile depth in the rolling direction.
  • the calibration and relaxation zones described above can be formed by means of small ramps at the end sections of the rolling rods, wherein the region of the rolling rods extending between the ramps is formed essentially with the same profile depth.
  • Each of the two rolling rods is in each case assigned a guide carriage, which is displaceable along inclined guides.
  • These two inclined guides are employed in a V-shaped manner with respect to one another, so that the radial distance between the rolling rod and the workpiece can be changed by displacing the guide carriage along the associated inclined guide.
  • the feed movement is carried out by moving the rolling rod along the wedge-shaped inclined guides, so that by adjusting the rolling rods without tool change a variation of the number of teeth, the rolling of even and odd numbers of teeth, a positioned rolling and the quality optimization of the profile by division correction is possible.
  • each guide carriage is assigned its own feed drive, for example a planetary spindle drive.
  • feed drive for example a planetary spindle drive.
  • suitable drives such as rack drives, ball screw drives or hydraulic drives can be used.
  • the structure of the cold rolling machine according to the invention can be further simplified if the free end portions of the guide slide displaceable along the inclined guides are connected via a console on which the drives for the rolling rod device are mounted.
  • the inventive concept can be used particularly advantageously in cold rolling machines, the rolling rods are driven in the vertical direction, so that the footprint of the machine according to the invention is minimal.
  • the height can be minimized by driving the rolling rods in the horizontal direction.
  • the workpiece can be driven via the rolling rods transmitted forces or via its own rotary drive, which is synchronized with the drive of the rolling rods.
  • the forming area of the workpiece is subjected to ultrasound.
  • ultrasound the flow limit is lowered during the forming process, so that the forming forces are reduced compared to conventional solutions.
  • the guide rails supporting the inclined guides are advantageously supported on two spaced support legs of a machine bed, these two support legs are connected to increase the rigidity over cross straps.
