Definitions

  • the beard chisel (6) according to the invention which is wear-resistant due to its self-rotating grinding and inexpensive due to its round, flat shape, has been replaced by a much more expensive and more wear-resistant beard chisel (7) developed.
  • the higher wear and tear and the higher costs must be offset by sufficient other advantages.
  • An advantage could be a higher number for the production, if the usual beard caps (6) could also be replaced by the new beard chisel (7). To do this, the specific service life would have to be increased. This means that they could be used for cold and warm beards (1) at the same time.
  • the beard chisel (7) in the area of the cutting edges (8) is made wear-resistant by welding on a very expensive but sufficiently hard and tough material even when heated.
  • a particular contradiction when changing from round beard caps (6) to rectangular beard chisels (7) is the higher deburring force required for cold beards compared to warm or hot separating beards.
  • the round beard cap (6) has previously been pressed against the burnt beard (1) only with an arcuate part of the leading edge and therefore only a part of the total deburring energy per beard cap (6) and thus only a lower deburring force is initially required.
  • a smooth movement of the deburring piston (4) by lubrication over its entire length, a tolerance-preserving cooling of the same and the cylinder liner (12) and also a lubrication of the rubbing and shearing deburring process on the deburring tool (5) are made possible by the fact that in shown, both the sealing ring (13) and the scraper ring (14) are sufficiently broken for the compressed air outlet.
  • the annular gap (15) between the embedding piston (4) and the cylinder liner (12) must be approx. 0.1 - 0.3 mm
  • the sealing ring (13) has keyway-type passages (16) of 0.5 x 5 mm the piston side (6). This controls the amount of compressed air.
  • claims 5 and 6 also list deburring tools (5) which are particularly advantageous in terms of production technology. It is according to around triangular blocks on a lathe faceplate (21) fixed in a circle around the middle of them using the later mounting holes of the deburring tools (5) on the debarring piston (4) and then worked on the outside with R 1 and on the inside with R 2 in the area of the upper working form by turning, specifically to bring up the working form, the preparation of the weld seam and the corresponding cut-backs or the rework after welding. The other sides and tips of the triangle can also be machined by repositioning by 180 °.
