Definitions
- the present invention relates to a device for decoring casting pieces which is particularly but not exclusively useful in the casting industry for aluminum alloys and the like.
- Breaking the shell is in itself an extremely simple operation, since it is sufficient to shake the casting, while in order to free the casting from the core it is necessary to act violently, for example with a pneumatic hammer, on the core until it breaks up, and then make the sand thereof exit from the casting through the openings of the casting. It is evident that this typically manual method is unfeasible in medium, large and very large mass-productions.
- sand flogging, or knock-out, devices have been provided which consist substantially of a platform which supports a percussion member and a fixed abutment which face each other and between which the operator places the casting, after it has been freed of the shell, in order to subject it to strong vibration so as to break up the internal core.
- a first drawback of these devices is the rather long time required to perform the process, due both to the difficulties that operators encounter in handling the parts and to the efficiency and. effectiveness of the apparatus itself, accordingly entailing significantly high labor and running costs.
- a second drawback is due to the higher-than-normal noise and vibrations to which operators of this device are exposed.
- US-5,213,150 discloses a core knock-out fixture mounted on a door of a cabinet for holding a casting against a vibrating plate inside the cabinet.
- the aim of the present invention is to overcome the above cited drawbacks of the prior art devices for decoring casting pieces.
- An object of the invention is to provide a device for decoring casting pieces which allows to minimize manual intervention.
- a further object of the invention is to minimize the process times, achieving a considerable economic advantage with respect to the prior art devices.
- a further object of the invention is to provide a device for decoring casting pieces with constructive solutions which drastically reduce the transmission of vibrations to the floor and accordingly to the operators and the overall noise of the process.
- Still a further object of the invention is to provide a device for decoring casting pieces which complies with the limits and constraints of applicable statutory provisions covering workplace hygiene and safety.
- the device for decoring casting pieces comprises a metal frame 2 which is composed of a pair of facing vertical portals 3 and 4 and by lateral longitudinal members 5 for joining the portals 3 and 4.
- Three wings 6 protrude within the area formed by the front portal 3.
- One of the wings protrudes from the upper cross-member and two of the wings protrude from the lower cross-member, and each wing rotatably supports a guiding member 7.
- three wings 8 protrude within the area formed by the rear portal 4. Two of the wings protrude from the upper cross-member and one of the wings protrudes from the lower cross-member, and each wing rotatably supports a guiding member 9.
- the vibrating means 10 comprises a first tubular body, generally designated by the reference numeral 11, whose longitudinal axis is parallel to the floor.
- the tubular body elastically accommodates a second coaxial tubular body, generally designated by the reference numeral 12, which in turn supports a pneumatic vibrating head, generally designated by the reference numeral 13, at its front end.
- An actuation source such as a gearmotor 14 arranged on the frame 2 in an upward region, and a transmission member, associated with the first tubular body, in the specific case an annular ring 15 which surrounds it circumferentially, which are mutually connected by means of a motion transmission member, for example a chain 16, turn on command the vibrating means 10 about the longitudinal axis of the first tubular body 11.
- a motion transmission member for example a chain 16
- the first tubular body 11 is composed of two first facing annular members 18a and 18b which are joined by welding to four first bars 19 which have the same length, are arranged around their perimeter and are evenly spaced.
- the outer edge of the first annular members 18a and 18b which faces the guiding members 7 and 9 is shaped so as to form rolling tracks for the members.
- the outer edge of the first front annular member 18a is raised so as to engage complementarily shaped circumferential grooves formed in the guiding members 7.
- the second tubular body 12 is formed by a second rear annular member 20 and by a front circular plate 21 which face each other and are joined by welding, as in the first tubular body 11, to four second bars 22 which are in turn rigidly coupled to the first bars 19 by interposing, at their ends, elastic inserts 23, for example small rubber cylinders.
- the front plate 21 is centrally provided with a through hole for accommodating the vibrating head 13 and rigidly supports the casting clamping means, generally designated by the reference numeral 24.
- the vibrating head 13 comprises a tubular member 25 which is fixed to the plate 21 inside its central hole, a percussion means 26, which is accommodated within the tubular member 25, and can mutually slide axially by pneumatic actuation between a retracted position (Figure 3) with respect to the casting (G) and a forward position ( Figure 4) in contact with the surface thereof, and a front lid 27 for closing the tubular member 25 with a central hole for the passage of the percussion means 26.
- the clamping means 24 is constituted by a first fixed jaw 28, which is rigidly connected by bolting to the plate 21, and by a second jaw 29, which can move between a spaced position (Figure 3) with respect to the first jaw 28, for loading and unloading the casting (G), and a closer position ( Figure 4) for locking the casting.
- the first jaw 28 has a central through hole, which corresponds to the hole of the lid 27 and from which the front portion of the percussion means 26 protrudes when the percussion means is in the forward position, and supports, at its ends, two cylindrical guides 30 which are engaged in corresponding holes, formed at the ends, of the second jaw 29 which in turn is provided with a central hole which is aligned with the hole of the first jaw 28, for accommodating a member 31 for reacting to the action applied by the vibrating head 13.
- the reacting member is constituted by a mushroom-shaped pin 32, whose stem is partially inserted in the hole and whose head is in contact with the surface of the locked casting (G), and by a pack of springs 33, for example of the Belleville type, which are interposed between the head and the second jaw 29.
- the sand flogging device 1 comprises a soundproofing enclosure, generally designated by the reference numeral 34, which can be opened by moving, in guillotine fashion, a front panel 35 and an upper panel 36 for loading and unloading the parts.
- the sand flogging device also includes a control console (not shown) of the keypad type for actuating, stopping and controlling respectively the rotation of the vibrating means 10, the vibrating head 13, the front panel 35 and the upper panel 36.
- the sand flogging device 1 is provided with a bracket-like structure (not shown) which is preset for a series of castings (G) and is rigidly connected to one of the jaws 28 and 29.
- a bracket-like structure not shown
- the operator loads a casting (G) onto the bracket system and then, after closing the front panel 35 and the upper panel 36, locks it between the vibrating head 13 and the reacting member 31, actuating the clamping means 24 by means of the keypad.
- the operator activates the vibrating head 13 and turns, according to requirements, in one direction or the other the vibrating means 10.
- the core (A) subjected to the vibrating action, begins to break up and the grains of sand begin to flow out continuously from the openings of the casting (G).
- the operator stops the vibrating head 13 and the rotation of the vibrating means 10, so that the casting (G) arranges itself in the initial position; then he releases the clamping means 24, opens the front panel 35 and the upper panel 36 and manually unloads the casting (G). The operation is repeated likewise for the other castings of the series.
- the described sand flogging device achieves the intended aim and objects, since it achieves a true reduction in operating costs due to the significant reduction in the time for which workers handle the castings and due to the speed of execution of the process. Furthermore, by providing, inside the factory, processing stations which are composed of a plurality of sand flogging devices, it is possible to optimize the casting processing cycle. Careful choice of the components and their assembly allow the sand flogging device to easily exceed the statutory standards covering workplace health and hygiene, significantly helping to improve the working conditions of the personnel.
