Definitions

  • the invention relates to a roller for a radial thread rolling head according to the Preamble of claim 1.
  • the thread form profile seen in the circumferential direction a flat, a thread inlet section, a thread calibration section and a thread run-out section.
  • the sections mentioned extend over a certain angle. So the flattening usually extends over an angle of about 40 ° Inlet section over an angle of 160 °, the calibration section over a 90 ° angle and the outlet section over an angle of 70 °.
  • the length of the Calibration section is usually such that it is a multiple of Corresponds to the circumferential length of the workpiece to be shaped.
  • Thread rolls Due to the frictional connection between the workpiece and the thread rolls, the Thread rolls rotated, and a spring mechanism is tensioned, and after completion of the rolling process, a clutch is engaged so that the thread rolling Release the workpiece again.
  • Such a thread rolling head or form rolls for such thread rolling heads are from DE 39 30 131 C1 or Fette company script Roll systems "became known.
  • the rollers usually have a certain axial length. This can be for one given execution of a rolling head can no longer be changed. On the other hand it happens with a number of uses that the thread forming roll only over a limited axial area is used. This area wears out with the Time while the rest of the area remains operational, but because of its location is unused.
  • the invention is therefore based on the object of a form roller for a radial thread rolling head to create the most effective for the formation of short Thread sections is suitable, but allows full utilization.
  • an annular circumferential groove section is formed on the circumference.
  • This groove section does not extend into the flattened area or it is not required to lead him into this area.
  • a thread form profile molded in that has an opposite pitch has, the flats of the thread form profiles aligned with each other are.
  • this is a thread form profile for a right-hand thread
  • the other thread form profile is also suitable for right-hand threads, if the roll is rotated 180 ° in the roll head. It is possible to use identical ones Thread form profile sections to form identical threads in the workpiece.
  • the groove ensures that the workpiece is not with the second shape profile section comes into engagement. Therefore corresponds to one more Embodiment of the invention, the width of the groove at least the slope of the Thread form profile plus a certain amount of excess.
  • the groove should preferably also have a minimum depth that is equal to the height of the profile plus a minimal inlet stroke.
  • the thread forming roller shown in FIGS. 1 to 3 has two thread form profile sections on the circumference 10, 12, which are separated from one another by a groove 14.
  • the thread form profile 12 has a flat 16, one approximately 160 ° extending inlet section 18, an approximately 90 ° extending Calibration section 20 and an outlet section extending approximately over 70 ° 22 on.
  • the profile section 10 has a flat 24, an inlet section 26, a calibration section 28 and an outlet section 30. How from 2 and 3, the flats 16, 24 are aligned with each other, and the remaining sections of the shaped profiles are the same, but symmetrical to Center plane, which is spanned by the groove 14.
  • Thread molding section 10, 12 in the same way to that also not shown Workpiece with which it is brought into engagement.
  • Threads generated depending on which thread form profile 10, 12 is used. Is therefore z. B. the profile section 10 is worn out, the role in the thread rolling head Inserted rotated 180 °, so that the profile section 12 is now used reached. In this way, the entire length of the profile roll can be used, what the role has a significant service life. This only applies to relatively short ones Thread sections to be formed, but these applications are relatively common.
  • the thread profile sections 10, 12 are identical have to be. Rather, they can have a different slope and also a different hub.
  • the Radial profile height of the inlet section compared to that of the calibration section shifted inwards. This is indicated in FIG. 3 by the dashed line 32, which represents the final profile height.
  • the radial offset, marked with 34 is also referred to as a hub.
  • the outlet section 22 or 30 results there is also a relocation of the profile height in the direction of the flat 16 or 24 to facilitate the roll out of the roll on the workpiece.
  • a thread forming roll is shown, the two thread profile sections 10a, 12a, which are separated from one another by a groove 14.
  • the groove 14 corresponds of groove 14 according to FIG. 1.
  • the thread profile sections have 10a, 12a a different diameter.
  • the groove 14 should also be noted that it has a width that is slightly larger than that Slope of the shaped profile sections. This also causes a certain overflow at the Formation of the thread on the workpiece possible.
  • the depth of the groove 14 corresponds to that Profile height of the shaped profile sections plus a minimal inlet stroke. Thereby there is no groove in the flattened area 16 or 24.
