Definitions
- the present invention due to the collaboration of Jean-Paul ROUGIER, is from the field of foundry. It relates more precisely to a device making it possible to separate a foundry part from the flyweight to which it is connected. De-bashing is a common foundry operation.
- the present invention aims to provide a portable device allowing this operation to be carried out more silently and without shocks, while avoiding false maneuvers.
- the dismantling device according to the invention is characterized by the fact that it consists of jaws, connected by a system of links to the outlet flange of a body of hydraulic jack whose piston is secured by its free end to a corner mounted sliding between the two jaws so as to cause their separation almost instantaneous during the actuation of said jack.
- FIG. 2 is a side view of the dismantling device of FIG. 1 in operation
- FIG. 3 is an exploded partial perspective view of a dismantling device according to the invention.
- the sorting device consists of a wedge 3 slidably mounted between two jaws 4a, 4b, each connected by a system of links 5a, 5b and pins 6a, 6b, 7a, 7b, to the outlet flange 2 a cylinder body or cylinder 1 the end of the rod of which is secured to the base of the corner 3.
- jaws 4a., 4b On the internal face of the jaws 4a., 4b are respectively provided pads that ⁇ e d ⁇ round 14a, 14b intended to slide in longitudinal recesses of corresponding shape 3a, 3b provided on the bevelled faces of the corner 3.
- the jaws 4a, 4b places between the counterweight and the foundry piece (not shown in the drawings) simply move away under the action of the wedge 3 so as to be almost instantaneous and very powerful , jaw spacing speed being increased because the jaws 4a, 4b being retained by the links 5a, 5b, the latter also open by pulling said jaws backwards.
- the jaws are changed very easily by uncoupling the axis which connects them to the link.
- This operation takes place according to the following process: a) the pin E is taken, which is for example of the agricultural tractor pin type (this pin is however not necessary if the device is always used horizontally; the studs 6a and 6b then hold by gravity); b) the studs 6a, 6b are raised; c) the two connecting rods 5a, 5b are removed (these can be linked in rotation with one another to simplify the operation of replacing the stud); d) the coin-jaw assembly is rotated (the assembly is linked to the hydraulic piston which naturally rotates in the cylinder); e) the jaw 4 is removed towards the rear, by sliding of the element 14 out of its housing 3a; f) the new jaw is introduced from the rear to the front, then, after having replaced the example bit-jaw in its starting position, the bolt 6 is relocked.
- This operation requires about twenty seconds, which constitutes another appreciable advantage of the de-balancing device according to the invention.
