Definitions

  • the invention relates to a method for producing a profile of a profile knife by means of at least one grinding tool according to the preamble of claim 1.
  • the profile knives must be provided with the required profile.
  • a template is made that has the necessary profile.
  • the template is clamped in a template holder, while a blank for producing the profile knife is clamped in a holder.
  • the grinding tool With the grinding tool, the corresponding profile is then ground into the knife blank by scanning the profile of the template with the copying part.
  • the profile knives are manufactured one after the other.
  • alignment surfaces are required on the profile knives that interact with cam-like approaches of a clamping wedge of a clamping device of the processing machine. The profile knives therefore have a complicated shape.
  • the installation of the profile knives in the cutter head is complex. That is why the tool change is time-consuming, and the changeover and downtimes of the processing machine are relatively high.
  • the exact position of the profile knives in the processing machine must be checked, for which a test run is carried out. This requires a workpiece every time, which is always rejected if the knife setting is not exactly correct.
  • the invention has for its object to design the generic method so that the profile knives can be manufactured so that a simple tool change is possible, the reject rate is minimized when checking the position of the profile knives and the changeover and downtimes of the processing machine are reduced to a minimum .
  • the profile knives to be ground are clamped in the cutter head, so that an exact assignment of the profile knives and their profiles to the cutter head is guaranteed at all times.
  • the profile knife is clamped in the cutter head in the method according to the invention in such a way that the profile start of the profile knife has a predetermined distance from the cutter head stop, which corresponds to the distance that the profile start of the workpiece has from the system of the machine spindle to which the cutter head in the processing machine , preferably a moulder.
  • the exact position of the cutter head for the grinding process can be set very easily by bringing the cutter head into contact with the stop of the holder.
  • the knife head with the ground profile knife can then be pushed and clamped immediately on the spindle of the processing machine.
  • the profile knife then takes up its exact position within the processing machine, so that the cutter head with the ground profile knives can be put into operation without carrying out a test run. A corresponding workpiece scrap therefore does not occur.
  • the changeover and downtimes of the processing machine for the tool change are extremely short as a result of the method according to the invention.
  • a tool change in a moulder can be carried out quickly and easily. This is achieved in that a template according to which a profile knife is produced, a grinding machine for producing this profile knife and the moulder are matched to one another. The reject rate for adjustment work is reduced to almost 0 as a result of this facility. The changeover and downtimes of the moulder are reduced to a minimum.

  • the grinding wheel 21 is precisely aligned with respect to the profile knife 9 to be ground.
  • a zero washer 13 is also inserted on the stop pin 12 on the left in FIG. 2 (dash-dotted line), and the profile template 1 with its side opposite the stop side 4 is placed against the zero washer.

Since in the starting position the copier pin 24 also bears against the stop side 4 of the profile template 1, the profile knife is aligned with the grinding wheel in exactly the same way as that Profile template 1 with respect to the copy pin 24th
  • the profile 26 in the profile knife 9 is produced in a known manner by moving the template carrier 10 with the grinding arbor 14 over the cross slide 28 in such a way that it gropes along the copy pin 24 in a known manner is guided along the profile 6 of the profile template 1. To the same extent, the grinding wheel 21 grinds the profile 26 in the profile knife 9.
  • the profile template 1 rests with its stop side 4 on the zero disk 13.
  • the profile 6 of the profile template 1 begins at a distance 8 from the stop side 4, as has been explained with reference to FIG. 1.
  • the cutter head 31 with the bearing part 32 is designed such that the beginning of the profile 26 of the profile knife 9 also begins at a distance 8 from the side 19 of the collar 17.
  • FIG. 4 shows an embodiment of a cutter head 31a that is not hydraulically clamped on the spindle head 14 with a bearing part. Rather, the cutter head 31a is attached to the spindle head 14 in a conventional manner. Since the cutter head 31a has no protruding bearing part, its end face 34a lies directly against the side 19 of the collar 17. If, as in the exemplary embodiment according to FIG. 3, the profile template 1 were in contact with a zero wheel, then the grinding wheel 21 would start to grind the profile 26 on the profile knife 9 at too great a distance from the side surface 33. The beginning of the profile of the profile knives would then, depending on the cutter head in which the profile knife was clamped during the manufacture of the profile, start at a different distance from the side surface 33.
  • the distance 35 between the The two stop pins 12 correspond to the length 20 of the grinding arbor 14 plus the distance 8 that the beginning of the profile 6 has from the stop side 4 of the profile template 1.
  • the distance 35 is 245 mm in the exemplary embodiment and is the basic dimension of the template carrier 10 when the profile knife 9 is clamped in the cutter head 31a.

  • the start of the profile 26 of the profile knife 9 is at a distance 36 from the side surface 33.
  • the distance 36 is exactly half as large as the distance 8.
  • the beginning of the profile begins with the profile knife clamped in the cutter head 31a 9 with the distance 36 from the corresponding side surface 33.
  • the zero wheel 13 is placed on the stop pin 12, as will be explained with reference to FIG. 2. Since the cutter head 31a has no axially protruding bearing part, the zero disk 13 is removed from the journal 12 as compensation when grinding the profile knives 9.
  • the template carrier 10 is moved until the profile template 1 rests on the stop pin 12, the grinding wheel 21 is displaced to the same extent into the position shown in FIG. 4. It then has the distance 8 from the start of the profile 26 of the profile knife 9.
  • the profile template 1 thus shifts by the wall thickness of the zero disk 13. This dimension is at the same time the difference between the distance 8 and the distance 36.

  • the stop edge 38 is located at a distance 8 from the system 39.
  • This distance 8 also corresponds to the distance from the start of the profile 26 of the knife 9 from the contact surface 32 'of the bearing part 32 bearing against the spindle stop 39. Since the profile knife 9 in the manner described above has been made that the beginning of the profile has the distance 8 from the end face of the contact surface 32 ⁇ , the cutter head 31 can be mounted precisely on the spindle 37. It is only pushed open until the contact surface 32 ⁇ comes to rest on the spindle stop 39. Then the cutter head 31 with the profile cutters 9 is exactly aligned with the stop edge 38. The spindle 37 is thus set to the basic axial dimension 8 behind the stop edge 38. In this way, all the spindles of the moulder that carry the cutter heads 31 are aligned relative to the stop edge.
