Definitions

  • the invention relates to a flow swivel drum, which is provided with an upper jacket opening, is inclined in the longitudinal direction and is pivotally mounted about its axis, for the continuous blasting of workpieces traveling through the drum in the longitudinal direction with the aid of centrifugal wheels.
  • Such a flow swivel drum as is known for example from DE-OS 24 24 086, is continuously swiveled between two limit positions during the blasting process.
  • the workpieces traveling through the flow swivel drum should not only slide longitudinally along the drum, but also rotate about themselves, so that they are struck on their entire surface by the blasting agent which is blown by the centrifugal wheels through the jacket opening in the drum is blasted. Practice shows that this turning around itself does not take place to the desired extent on all workpieces.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of equipping the flow swivel drum with a device which inevitably causes the workpieces in the drum to rotate about themselves brought about, at least significantly favored.
  • the workpieces sliding on the inside of the drum shell during its pivoting movement in the circumferential direction can only do this until they reach one of the turning stages.
  • the workpiece In the turning stage, the workpiece is initially held longer than it corresponds to the swivel angle of the drum shell; until the workpiece is rolled over when the swivel angle is increased further, which then lies against the inside of the swivel drum with another surface.
  • the part of the workpiece surface that faces the opening in the jacket and thus the blast wheels and is blasted changes at the turning stages at the latest every second swivel of the flow swivel drum.
  • the flow swivel drum shown in the figures has an inlet drum 1 in the longitudinal direction, followed by a jet drum 2 and then a sieve drum 3.
  • the flow swivel drum is - which is not shown in the drawing - inclined in the longitudinal direction, so that Workpieces during the swiveling of the flow swivel drum are conveyed in a natural way from the inlet of the inlet drum 1 to the outlet of the sieve drum 3.
  • the inlet drum 1 is narrowed towards the feed side in the manner of a funnel 4.
  • the inlet drum 1 has a flange ring 5 on the end face facing the blasting drum 2.
  • the sieve drum 3 also has a flange ring 6 on the end face facing the blasting drum 2; followed by a support ring 7 towards the outlet side.
  • the bottom of the screening drum 3 is largely designed like a screen 8.
  • a race 11 is provided on the outside of its jacket 10 on each end face of the blasting drum 2.
  • the race 11 on one end face is screwed to the flange ring 5 of the inlet drum 1, which on the other end face is screwed to the flange ring 6 of the screening drum 3 and the associated support ring 7 by means of screw bolts 12.
  • the bottom of the blasting drum 2 is provided with longitudinal openings 13.
  • a casing opening 14 is left open in the jacket 10, through which blasting media emerging from centrifugal wheels hit the workpieces transported, pivoted and turned in the blasting drum 2.
  • the jacket opening 14 is reinforced laterally in the region of its two side edges by an I-beam 15 each. Other reinforcements are possible.
  • the jacket 10 is provided on its side opposite the jacket opening 14 with a turning stage 16.
  • the turning stage 16 extends between the inner surfaces of the races 11. It can extend over the entire length of the blasting drum 2.
  • a turning bar can also be used as a turning stage or a turning edge can be provided.
  • the decisive factor is that when the jet drum 2 is pivoted to the turning stage, bar or edge, the workpieces do not simply slide further along the inner surface of the jacket 10 when the swivel angle is increased, but rather roll over, so that another part of their surface faces the jacket opening 14 , which ensures uniform irradiation of the workpieces.
  • the turning stage 16 is in the exemplary embodiment than in the shell 1 0 pushed outwardly formed in a substantially V-shaped groove.
  • One leg surface 17 of the turning stage 16 merges tangentially into the jacket 10; the other leg surface 18, which is substantially perpendicular to the first leg surface 17, merges into the jacket with a kink.
