Definitions

  • the invention relates to a portable blasting machine with an endless special belt running over rollers and a rotatable disc provided on its outer surface with a profiled bandage, the special belt partially wrapping around the bandage and the blasting material between the outer surfaces of the bandage and the special belt being accelerated.
  • the object on which the invention is based is to propose a device of the type mentioned in the introduction, in which a secure positive guidance of the special belt is ensured, so that the special belt does not slide off the rollers during operation of the blasting material centrifuge. Furthermore, it should be possible to spin the blasting material as precisely as possible without the special belt being able to slide sideways. Retensioning the special belt should be possible in a simple manner.
  • the outer surface of the bandage has circumferential grooves and that the inner surface of the special belt is provided with a profile running parallel to the circumferential direction, in which the outer surface of the rollers guiding the special belt engages with a corresponding profile.
  • the special belt partially wrapping around the bandage is frictionally carried along by the bandage, the blasting material lying between the grooves of the bandage and the special belt.
  • the blasting material supplied is grasped, accelerated and then thrown off tangentially.
  • the special belt is positively guided on its inner surface via the interlocking profiles of this inner surface and the outer surface of the rollers, the special belt not being able to slide laterally from the rollers. This ensures that the special belt remains securely in its position even when the blasting material is fed unevenly.
  • the blasting material is accelerated between the circumferential grooves of the bandage and the outer surface of the special belt. This mode of operation is similar to a belt drive only under other conditions.
  • the disc 2 with bandage 3 is driven by the electric flange motor 1.
  • the disk 2 is provided with the bandage 3 on its outer surface.
  • This bandage 3 is designed with conveyor grooves, which each overlap the surface of the disk with a collar on one side, and is fastened to the disk 2 by means of bores with a fastening screw 4.
  • the centrifuge housing 5 serves as protection and for attaching further parts.
  • the blasting material container 6 is firmly connected to the housing 5 by the tab connection 19. After opening the gate valve 8, the blasting material 7 can slide (open / close) into the movable hose 10 using the operating lever 9.
  • the hose 10 is designed in particular as a rubber hose and guides the blasting material 7 to the blasting material feed pipe 11, which is fastened on the annular disc 12.
  • the washer 12 is cross-divided, is used with the threaded clamping bolt 16 for retensioning the special belt 15 and carries the beam feed tube 11, the two rollers 14 and 26, the threaded clamping bolt 16 with right and left hand threads, the two threaded stops 17 and the pivot lever 18 and the push rod 25
  • the ring disk guide 13 is designed as a tab guide.
  • the endless belt 15 runs over the two rollers 14 and 26. Die. Rollers 14 and 26 have on their outer surface the profile 29 which engages in the profile 28 on the inner surface of the special belt 15. These profiling formed as circumferential grooves prevent the special belt 15 from sliding off the rollers 14 and 26.
  • the profiling 28 and 29 run over the entire width of the special belt 15 or the rollers 14 and 26. They interlock with one another. Furthermore, the bandage 3 is provided with circumferential grooves 27 which are semicircular in cross section. The blasting material 7 is located in these circumferential grooves 27 of the bandage 3 and the special belt 15. The resulting beam 21 strikes the object 20 to be blasted. The handle 22 is fastened to the housing 5.
  • the blasting material 7 introduced between the bandage 3 and the special belt 15 via the blasting material feed pipe 11 is grasped and brought to the required speed so that it hits the object 20 to be processed as a beam 21.
  • the swivel lever 18 With the swivel lever 18, a change in the emerging beam direction can be effected by adjusting the annular disc 12.
  • a change in the tension of the special belt 15 is made possible via the rollers 14 and 26.
  • the annular disc 12 is brought into pivoting movements by means of an eccentric disc 24 with a motor.
  • the push rod 25 establishes the connection between the eccentric disc 24 and the annular disc 12.
  • the blasting material centrifuge has a continuously operating and pivoting annular disc 12. If this device is operated with the eccentric disc 24, the larger and elongated beam surface 23 is obtained in contrast to the beam 21.
  • This additional device has very great advantages because the beam surface length can be adapted to the workpiece surface. No blasting material is lost, the areas are hit more intensively and they are irradiated in a shorter time. Manual operation of the swivel lever 18 according to FIG. 1 is not possible by the operator in such a uniform manner, so that an unclean spray pattern is produced.
  • the special belt 15 runs with circumferential grooves in the two grooved tensioning rollers 14 and 26 and thus prevents the bandage 3 from running off when the blasting material is supplied unevenly.
  • the bandage 3 guides the special belt 15 laterally through the edges of the rim, so that this also prevents the bandage 3 from running off.
  • the pretensioning of the special belt 15 presses it against the bandage 3, acts in a force-locking manner and thereby encloses the blasting material 7 in the deep grooves 27 of the bandage 3 and thus causes acceleration by the bandage 3 and the special belt 15, which is similar to a belt drive.
  • the tensioning of the special belt 15 and the adjustment of the split washer 12 is effected by the threaded clamping bolt 16 with right and left hand threads.
  • a device according to the embodiment shown in the drawings has proven itself well in trial runs.
