Definitions

  • the present invention relates to a device for Surface treatment, such as deburring or Descaling castings or castings or Forgings by means of sandblasting, having one rotatable drum in which the pieces or bodies be sandblasted, and a method using a Contraption.
  • Freshly cast castings or castings as well Forgings usually have a rough surface on, brows, sprue position and the like, which by means of Sandblasting can be reworked.
  • Medium size and smaller parts, such as connecting rods for Motor vehicles are usually in a rotating drum processed. After finishing the processing, these will be Castings or castings as well as forgings Open the bottom of the drum down, whereby due to a drop of approx. 1 - 2 m the surface of these pieces can be injured, i.e. it can be smaller Nicks or marks, such as so-called marks, arise which are outside of tolerance limits, which can result in relatively high failure rates.
  • the rotating drum in which the castings or castings are sandblasted is formed in at least two parts, such that a removable bottom part is provided, which of the Can be separated, preferably lowered, in one Transport device can be placed integrally with Castings or castings to be loaded or around the surface-treated castings or castings again discharged.
  • this is Bottom part integral in a transport device placeable, having an upstream Feeder and a downstream Collection device, being used for the transport of the castings or castings or forgings at least one each Vibration drive unit is provided to that Transportable surface-treating goods.
  • a method according to the wording is also proposed according to claim 8.
  • the surface to be treated Good or the castings or castings as well as forgings by means of vibration technology into a bottom part of a rotatable one Drum transported, then the drum is each closed at the front and for example by lifting and coupling to another drum part to one in itself closed, rotatable drum assembled, whereupon the Surface treatment of the goods takes place. After done The surface of the drum is treated uncoupled again, whereupon again using vibration technology the treated goods in a collecting facility is transported.
  • the device proposed according to the invention as well the method is particularly suitable for Surface treatment or deburring of medium-sized and smaller castings or castings, such as connecting rods for motor vehicles.
  • Figure 1 shows in cross section and simplified one Device 1 for sandblasting castings and Castings and forgings for their Surface processing as it is known from the prior art is known.
  • a sandblasting device 5 is provided for injecting the sand for surface treatment.
  • a resealable bottom part 9 provided by which after the completion of Surface treatment process the deburred and polished castings down into a drip pan 11 be delivered.
  • Sandblasting device which is the one used today Facilities, the big disadvantage is that when emptying the drum 2, the castings in the Catch pan 11 fall 1 - 2 m down and so Surface damage can result, causing excessive damage Failure rates can result.
  • the invention proposes that Form drum 2 in two parts by using the castings 7 not after the surface treatment be drained, but the lower bottom part of the Drum is lowered separably, then the surface treated Guide castings out of the bottom part.
  • FIG 2 shows schematically in longitudinal section Sandblasting unit 1 designed according to the invention, however having a detachable on the rotatable drum 2 Base part 4, in which the castings to be treated 7 to be ordered.
  • This lower bottom part 4 can be in one Transport device can be lowered, as in longitudinal section shown in Figure 2. Signed in the lowered state with the reference numeral 4 ', the bottom part of the Drum 2 in front of a loading device 21 with the charged raw castings 17 to be treated.
  • the Transport takes place by means of a vibration drive 23, with the drum facing the side Feeding device 21 is open.
  • the side opening 14 opposite the loading system closed and the bottom part 4 'raised to as bottom part 4 with the rest of the drum to be coupled together to the rotatable drum 2 form.
  • the sandblasting process can be started and the parts will be in the lower part of the drum surface-treated. After treatment, it will lower bottom part 4 uncoupled from the drum, lowered to turn in as a bottom part or as a tub 4 ' the transport device to be arranged integrated.
  • Figures 1-3 serve only for a more detailed explanation of the present invention and, of course, is one Device designed according to the invention for Surface treatment of castings or forgings not tied to the explanations in FIGS. 1-3. It is essential that in the sandblasting device provided rotatable drum for sandblasting the Castings is formed at least in two parts, such that a bottom part can be uncoupled from the rotatable drum is, for example, lowerable in order Transport device to be arranged integrally.
