Definitions

  • the present invention relates to a tumbling machine and according to the preamble of claim 1.
  • a machine is known from US-A-3624970 is particularly suited to carry out a series of finishing operations, such as degreasing, pickling, fettling or dressing-off,smoothing,washing and protection of mechanical components.
  • Both the rectilinear machines and the spiral machines have considerable overall size, and in both cases the pieces to be processed remain in the machine for a period of time that is proportional to the length of the machine and to the speed at which the piece advances, being, however, sufficient to carry out a single operation, for example, the dressing-off of the piece.
  • the speed of advancement of the piece may not, furthermore, be reduced beyond a reasonable limit, since any excessive slowing down thereof causes it to advance irregularly, and an excessive build-up of the pieces may arise, with the possibility of their damaging each other.
  • US-A-3,624,970 discloses a finishing machine comprising a plurality of finishing chambers joined together in the form of closed circle, but the chambers cannot move.
  • the object of the present invention is to provide a tumbling machine capable of overcoming the disadvantages referred to above and thus capable of ensuring a processing time for the piece or the pieces that is absolutely constant and widely adjustable with, furthermore, the possibility of carrying out, with almost total automation, a tumbling cycle in which the piece undergoes various treatments.
  • Figure 1 is a schematic plan view from above the tumbling machine according to the invention.
  • Figure 2 is a cross-sectional view along the line II-II of Figure 1;
  • Figure 4 is a scrap sectional view of a detail of the wear-resistant shell of a vibratory barrel of a tumbling machine according to the invention.
  • the machine comprises a plurality of tumblers 2a, b, c, d, e, f and g of the vibratory-tub type, a carousel support structure 3 on each tumbler is mounted, a series of processing stations 4, 5, 6, 7, 8, and 9 facing the carousel structure 3 on the perimeter thereof, and intermittent drive means 10 to advance the plurality of tumblers 2a, b, c, d, e, f and g in relative to the processing stations 4, 5, 6, 7, 8 and 9.
  • the carousel support structure 3 includes an annular base 15 supported upon a pedestal 16 and to which is fixed a guide 17 formed by a pair of circular concentric tracks 17a, 17b supported on the lateral walls 18 of the base 15.
  • Each tumbler 2a, 2b, 2c, 2d, 2e, 2f, 2g includes a frame 20 movable along the tracks 17a, 17b by means of supporting wheels 21 and guide wheels 22, all of which are freely rotatably mounted on the frame.
  • Each of the frames 20 is provided with a pair of buffers 25a, 25b at opposite ends, each provided with a buffer pad 26 and disposed in such a way that corresponding buffer pads of adjacent frames are in contact with each other.
  • a vibratory tub 31 is supported by means of springs 30,the details of the tub being more clearly visible in Figure 3; the vibratory tub 31 comprises an outer casing 32 to which the suspension springs 30 are connected by means of brackets 33.
  • the tub 31 is closed at the bottom by a curved base 34, in which there is a plurality of holes 35, and has an internal wear-resistant lining 36.
  • the mouth of the tub 31 opposite the base 34 is closed by a removable cover 37 made of or coated with sound-absorbent matrial, and in which there are formed slits 38a, 38b for the introduction of processing liquid.
  • cover 37 should be supported directly upon the frame 20, for example, by means of studs, not shown.
  • the introduction of liquid occurs at one or more of the processing stations 5, 6, 7, 8 and 9, each of which is equipped with a pipe 40 drawing from a reservoir 41 and terminating in a pair of spouts 42a, 42b aligned with the corresponding slits 38a, 38b of the cover 37.
  • the spouts 42a, 42b have a longitudinal extension which is smaller in size than the slits, so as not to require a precise positioning of the corresponding tumbler 2 upon the carousel structure 3 for the introduction of liquid into the tub 31.
  • the processing liquid introduced through the spouts 42a, 42b immediately flows from the tub 31 through the holes 35, draining into a collecting basin 44, formed in the base 15 of the carousel structure so as to be aligned with each of the processing stations equipped with spouts 42a, 42b.
  • the collecting basins 44 preferably have two inclined walls 45 disposed at opposite circumferential ends on the base so as to form a preferential mouth for recovery of the processing liquid, its filtering and possible return to the corresponding reservoir 41.
  • the station 4 at which loading and unloading of the piece or pieces to be processed in each tumbler is carried out, is provided with a vertically movable fork element 50 located in the base 15 and formed by a plurality of prongs 51,directed towards the base 34 of the overhead tub 31.
  • the fork element 50 is movable by a fluid pressure actuator 52 housed in a sump 53 below the pedestal 16.
  • the prongs 51 are thrust through the holes 35 of the base 34 of the tub 31, and are located in these holes with play in such a way as to lift the piece being processed out of the tub.
  • Each of the prongs 51 is provided at its upper end with a tip 55 made in a soft material so as to avoid any damage to the piece during lifting of the latter.
  • motor vibrators 56a, 56b of standard type, which impart vibratory stresses to granules, not shown, contained n the tub 31.
  • the intermittent drive means 10 comprise a thrust cylinder 60, pivotally mounted on the base 15 to which it is connected by means of a lug 61, and a training cylinder 62, also pivotally mounted by means of an eyelet on the base 15 and acting upon the thrust-cylinder 60 to effect training movement thereof.
  • the cylinder 60 has a stem 63 provided with a fork 64 which is removably engaged with a stake 65 carried by a striker 66 fixed to the frame 20 of each tumbler.
  • the station 4 is further equipped with a movable arm 70 of standard type for loading and unloading the pieces undergoing treatment or for the removal of the cover 27.
  • the wear-resistant lining 36 to advantage has a plurality of parallel inwardly projecting ribs 71 which prevent the piece from bearing critically upon the base 34 of the tub 31, thus avoiding any accidental damage 69 the piece.
  • the tumbling machine functions as follows: at station 4 the piece is loaded/unloaded into or out of the tubs 31 of the tumbler during its temporary transit beneath this station.
  • each of the tubs 31 in addition to the pieces to be processed, there are present granules of a conventional type of the size, conformation and in the quantity desired.
  • the prongs 51 of the fork element 50 penetrate the holes 35 of the tubs 31, so lifting the piece or pieces immersed in the granules through the mouth of the tank 31, the cover 37 having been previously removed.
  • the prongs 51 serve to free these holes of any granules that may possibly have become stuck therein or from any other possible obstruction.
  • the intermittent drive means 10 act upn the tumbler immediately preceding this so as to transfer it into a precise position above the fork element.
  • the thrust cylinder 60 retracts its rod 63 and is then trained by the fluid pressure cylinder 62 which carries this, in a retracted state, into a position opposite the striker 66 on the frame 20 of the tumbler 2g.
  • the training cylinder 62 is then disposed in a neutral position and follows the displacement caused by the main thrust cylinder 60 in transferring the tumbler 2g from the station 9 to the station 4.
  • the motor-vibrators carried on the tub 31 serve in a manner known per se to vibrate it to effect mechanical abrasion of the pieces.
  • the liquid introduced is drained through the holes 35, through which any undersized or worn granules, also pass, and is collected in the basin 44 formed in the base at each of the positions 5, 6, 7, 8 and 9.
  • the motor-vibrators may be inverted, in particular, if it is necessary to treat pieces with oppositely and threaded blind holes, which process permits all such holes to be freed from dirt, burrs and the like.
  • each of the said frames 20 carries two or more barrels up to the point where, for small-capacity tumblers, there is a single frame with a rotatable platform supporting the entire series of vibratory tubs.
