Definitions

  • the present invention relates to a metal chip shredder for direct attachment to metal processing machines.
  • chip shredders which make chips from the chips, which can then be better disposed of and recycled.
  • a known chip shredder has two rotatable shafts, on which there are disk-shaped knives arranged at a distance from one another, which mesh with the knives of the other shaft and rotate in opposite directions.
  • the present invention is based on the object of proposing a metal chip shredder which is designed to be as small and compact as possible with a throughput required for the usual machines and which is distinguished by high operational reliability and service life.
  • the metal chip shredder designed according to the invention has a chip shredding chamber in which a drum is arranged which is rotatable about its longitudinal axis. On the circumference of the drum there are spirally arranged cutting knives which enter correspondingly designed counter knives arranged on the inside on the long side of the chip size reduction chamber. Below the drum there is a sieve made of wear-resistant material that is adapted to the radius of the drum, and below it is a chip chip collection chamber. The cutting knives and counter-knives shred the chips that get onto the rotating drum until the chips can fall through the holes in the sieve.
  • the gap between the rotating cutting blades and the fixed counter blades is important. This must not be chosen too large, so that no uncrushed chips are drawn down to the sieve.
  • the metal chips to be shredded on the drum are automatically drawn in and shredded by the metal chip shredder.
  • the emulsions and rinsing liquids that are inevitably present can also be removed via the chip shredder and the sieve.
  • the hole size of the screen depends on the material to be shredded and the desired chip size.
  • the sieve as a sheet metal part made of steel with the alloy additives 0.15-0.22% carbon, 0.20-0.65% silicon, 1.0-1.7% manganese, ⁇ 0.025% phosphorus, ⁇ 0.025% sulfur, 0.80-1.5% chromium, ⁇ 0.50% copper, ⁇ 0.30% molybdenum and ⁇ 0.60% nickel.
  • Such a material is known under the designation VSS 295 and VSS 296 with the materials nos. 1.8704 and 1.8705 ensures a long service life when shredding metal chips.
  • the distance of the edge of the counter knife from the drum surface increases in the direction of rotation of the drum. This means that the smallest distance between the cutting knife and the associated counter knife, which is decisive for the comminution of the metal chip, is only at the foremost edges of the two knives.
  • the rake angle is negative according to a preferred embodiment.
  • the knives have the shape of an acute-angled triangle in cross section, the height of the triangle decreasing in the longitudinal direction of the cutting knives arranged on the drum.
  • the cutting knives arranged spirally on the circumference of the drum are advantageously arranged tangentially, so that the longitudinal axis of the knife blade runs vertically and the transverse axis of the knife blade runs parallel to the longitudinal axis of the drum and the cutting knives themselves are arranged parallel to one another.
  • the gap between the front edge of the cutting knife and the counter knife is preferably 0.1 to 0.3 mm, so that no uncut metal chips are drawn down to the screen.
  • baffle plate above the counter knife, which ends in the area of the entry of the knife into the area of the counter knife and is arranged at a distance from the surface of the drum, so that large, non-comminutable parts are held in the area above the drum and thus cannot lead to the blocking of the knives and the intake of the metal chips is promoted.
  • the device designed according to the invention thus ensures a small and compact metal chip shredder with high operational reliability, which allows the metal chips to be shredded directly on the chip-producing machine.
  • Figure 1 shows the metal chip shredder 1 with the motor 2, the gear 3 and the cutting unit 4.
  • the cutting unit 4 is the chip shredding chamber 5 with the triangular counter knives 6 on the long side.
  • a second arrangement of counter knives 7 on the opposite longitudinal side is designed in such a way that chips which have already been comminuted from below are carried on them Counter knives can be cut again.
  • the drum rotating in the chip shredding chamber 5 is not shown.
  • FIG. 2 shows the cutting mechanism 4 in cross section with the drum 8 rotatably mounted in the longitudinal direction about the axis 9 in the chip reduction space 5.
  • the drum 8 has cutting knives 10 on its circumference, which are arranged spirally over the circumferential surface.
  • the cutting knives are interchangeable insert knives with an acute-angled triangular cross-section.
  • the distance of the apex 11 from the drum surface 12 decreases from the cutting edge 13 to the rear edge 14 of the cutting knife 10.
  • the rake angle of the cutting knife 10 is negative.
  • the cutting knives 10 are designed such that they can run into the openings 15 formed by the counter knives 6 and shown in FIG. 1.
  • the counter knives 6 are arranged in such a way that the narrowest point is between the cutting edge 13 and the counter knife edge 16. It is 0.1 to 0.3 mm.
  • the sieve 17 arranged under the drum 8 is designed according to the radius of the drum and has a maximum distance of 0.5 mm from the front cutting edge 13 of the cutting knife 10. Below the sieve 17 there is a collecting space 20 for the chip chips passing through the perforation 19 (FIG. 3) of the sieve 17.
  • the baffle plate 18 is arranged above the counter knife 6 so that larger, non-crushable parts remain removed from the cutting area of the knives 6 and 10.
  • FIG. 3 shows a sieve 17 with two sieve holes 19 of different sizes, the smaller sieve hole serving in particular for the passage of the rinsing liquid or emulsion.
  • VSS 295 Of the Sieve itself is made of VSS 295 to ensure a long service life and operational reliability of the device. The thickness of the material depends on the types and sizes of the chips.
  • the drum 8 is shown in a side view, in which the recesses 21 for receiving the cutting knife 10 can be seen.
  • the cutting blades 10 are held in the recesses 21 by means of screw connections.
  • the spiral arrangement of the individual cutting knives can also be seen from this figure.
  • the cutting knives themselves are arranged parallel to one another, so that the apex 11 of the cutting knives 10 runs perpendicular to the drum axis 9 and the cutting edge 13 runs parallel to the drum axis 9, as shown in FIG. 5.
  • FIG. 5 shows the development of the drum 8 with the inserts of the cutting knives 10, the parallel alignment of the cutting knives and apices 11 and the cutting edges 13.
