Definitions

  • the present invention is in 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.
  • Dismantling 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 de-bashing device is characterized in that it consists of two 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 cylinder.
  • 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 studs 6a, 6b, 7a, 7b, to the outlet flange 2 a cylinder body or cylinder 1, the end of the rod 1a of which is secured to the base of the wedge 3.
  • dovetail pads 14a, 14b On the internal face of the jaws 4a, 4b are respectively provided dovetail pads 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 placed between the counterweight and the foundry piece simply move away under the action of the wedge 3 so as to be almost instantaneous and very powerful , the jaw spacing speed being increased by the fact that the jaws 4a, 4b being retained by the links 5a, 5b, the latter also open by pulling said jaws backwards.
  • the operation takes place in a silent manner and without jerks, while making it possible to routinely break sections of feeder necks of 100 mm in diameter thanks to the reduction due to the corner force, although it there is no theoretical opposition to breaking weights with a diameter greater than 100 mm.
  • the flyweight always breaks at the desired location, that is to say its channel connecting to the foundry piece.
  • This constricted area at the base of the counterweight which is always more heated during casting, has in fact a more fragile coarse-grained structure. This fragility is often reinforced by breaking points called in the foundry "breaking chamfers".
  • This operation requires about twenty seconds, which constitutes another appreciable advantage of the de-balancing device according to the invention.
