Definitions
- the invention relates to an installation for dismantling or destemming of foundry parts, of the type comprising a tool press for demasselotting or destemming of the parts which are presented under the tool at the work station on a lower tool. positioning, such an installation is oleja like.
- It relates to an embodiment of such an installation specially designed for rapid and safe mechanized handling of the parts to be treated as well as for dismantling or destemming any type of part, by lending itself to a rapid change of tools.
- the installation according to the invention comprising a tool-holder press for dismantling or destemming the parts presented under the tool at the work station on a lower positioning tool, is characterized in that it comprises a carousel with a star arm adapted at their free end to support the lower positioning tools by engagement of reciprocal shapes, and that the dismantling or destemming station includes a lifting device for each positioning tool in the dismantling position or de-stemming, this device being adapted to support the force of the press tool and to release the corresponding arm from the carousel.
- Figure 5 is a detail view in elevation and partial section of the lifting device of the lower tool at the dismantling station.
- FIGS. 1 and 2 The installation shown in FIGS. 1 and 2 comprises, with a vertical hydraulic press designated by 1 as a whole and intended to be provided with a de-balancing tool 2 movable along the vertical axis 3 of the press, a designated handling carousel par 4 as a whole and comprising star arms 5, here six in number, intended to be driven step by step with a rotational movement of 60 ° around the central axis 6 of the carousel, which is offset from to the axis 3 of the press so that the ends of the arms 5, intended to receive a tool for supporting the parts to be dismantled, are placed successively under the dismantling tool 2.
- a vertical hydraulic press designated by 1 as a whole and intended to be provided with a de-balancing tool 2 movable along the vertical axis 3 of the press
- a designated handling carousel par 4 as a whole and comprising star arms 5, here six in number, intended to be driven step by step with a rotational movement of 60 ° around the central
- the sorting tool 2 can be assembled with the tool holder 7 of the press by fitting therein two pins 8 integral with the tool 2, each pin being split at its end at 9 and then forming a socket 10 for engaging an assembly block 11 linked to the piston rod 12 of a hydraulic cylinder 13 mounted on the tool holder.
- the wedge 11 is guided movably in the tool holder between its assembly position shown in solid lines in the drawing and its erasing position shown in phantom in Figure 3, for which it is to be seen that the split end in 9 of the spindle is then freely engaged and disengageable relative to the piston rod 12 of the actuator of the wedge.
- the parts to be dismantled are arranged for the operation of dismantling on a holding cradle 15 of suitable shape, this cradle being secured , for example by screw, with a lower tool for positioning the part comprising a plate 16 which is positioned on the corresponding arm 5 by a simple engagement of form here provided using a lower yoke 17 whose cheeks overlap the arm 5 and have end notches 18 engaging on an axis 19 fixed transversely to the arm 5.
- This double engagement of the cheeks of the yoke 17 with the arm 5 and notches 18 with the axis 19 leads to positioning predetermined of the tray 16-cradle 15 assembly, and therefore of any part P disposed on the latter.
- the plate 16 further comprises at its lower part feet 20, here four being placed in pairs on each side of the arm 5, and with which is intended to cooperate an elevating device installed at the dismantling station and designated by 21 as a whole.
- Figure 2 as shown in more detail in Figure 5.
- This lifting device comprises a hydraulic cylinder, the cylinder 22 of which, fixed on a base 23, has a double outlet of the piston rod.
- the piston 24 in fact comprises an upper rod 25 on which is fixed a lifting plate 26 provided at its upper part with four pads 27 of distribution and shape adapted, here frustoconical, to cooperate with the ends of conjugate shape of the feet 20 of the plate 16 of the lower press tools.
- the piston 24 comprises a lower rod 28, under the lower face 28a of which, in the high position of the lifting plate 26, is intended to be engaged a blocking block 29 linked to the piston rod 30 of a hydraulic cylinder 31, the cylinder of which is fixed to the base 23.
- the carousel arm is therefore not subjected to the dismantling effort, while the jack 22-24 is here limited in its efforts to its lifting function, it being understood that the blocking block 29 is slid under the face 28a of the lower piston rod, so that the lifting device forms a sort of rigid heap of abutment resistant to the dismantling effort.
- the shim 29 is erased and the jack 22-24 fed from the top so that the lifting plate 26 is lowered to allow the lower tooling to come to rest on the arm 5.
- the simple engagement of shape provided between the plate 16 of the lower tool and the arm 5 not only allows this procedure of dismantling, but also allows to provide an easy evacuation of the part remaining on the lower tool (plate 16-cradle 15) at an evacuation station as designated by 35 as a whole.
- This station comprises a handling arm 36, mounted tilting in the extension of the corresponding arm 5 and provided with two fingers 37 movable under the action of jacks not shown, these fingers being intended to engage in sleeves 38 fixed under the plate 16 parallel to the axis of the arm 5.
- the handling arm 36 is pivotally mounted around an axis 39 held between two support uprights 40, and it has an articulation yoke 36a with the piston rod 41 of a cylinder 42, the cylinder bottom of which is itself articulated at 43 in a yoke 44 secured to a base 45 carrying the uprights 40.
- the lower tool (16-15) is brought back into position on the arm 5 of the carousel, ready to be reloaded with a piece to be dismantled by an operator at one of the other stop stations of the arm 5 considered which separate the evacuation station 35 from the dismantling station.
- a device for receiving and discharging the flyweights 14 which is formed by means of two troughs 47 which are placed on either side of the arm 5 and of the lower tool carrying the part to be dismantled, between the moment of presentation of the latter under the dismantling tool and the implementation thereof.
- These chutes 47 are for this purpose linked to tilting arms 48 mounted integral with an axis 49 which is pivotally installed between uprights integral with the press frame and which carries a central lever 50 articulated at 51 with the piston rod 52 of a jack 53, the cylinder 54 of which is articulated at 55 on the base of the device.
- the troughs 47 are then tilted upwards and outwards relative to the carousel, to the position shown in phantom, in which their outer wall 47a then forms an inclined plane for gravity unloading in a recovery box 56.
- chutes such as 47 which receive the parts during their destemming by the press tool and the evacuation station 35 which receives the part of the cluster which remains on the cradle after destemming of the parts.
