Definitions

  • the initial raw casting in step (1) may be produced by an appropriate process.
  • the casting operation may be carried out in a mould having a core associated therewith.
  • the mould may have an internal mould cavity of complementary shape to the desired shape of the raw casting and the core or core pin may be located in the mould cavity having one end thereof extending into a core retaining recess at one end of the mould cavity.
  • the molten metal as is usual with casting operations may be poured with the assistance of gravity into the mould cavity.
  • the mould may be formed by an upper mould component or "cope” and a lower mould component or “drag".
  • the core which is suitably formed from a mixture of sand and resin may be cast in the lower mould component part of the mould cavity and is responsible for forming an internal bore of the metal article of desired configuration.
  • the casting may be removed from the lathe which is preferably an NC (numerically controlled) lathe and reversed so that the front clevis or rod clevis end is mounted in the tailstock and the rear clevis end is mounted in the chuck.
  • the rod clevis end may be a pair of opposed holes formed in each fork or opposed part of the front bifurcated end by a suitably drilling tool and also a tapping tool associated with the tailstock of the lathe if a thread is required.
  • FIGS 3-4 there are also shown tie bolt securing lugs 17A in the form of a continuous outwardly extending rib of casting 9 together with adjacent cavities 18A for tie bolts (not shown). Also shown are opposed apertures 19A for a cross bolt facility.
  • FIG 9 there is also shown casting 9 supported in V-block 29B with hardened clamp pads 32A. Also shown is locating pin 29A.
  • the front end cap 39 may be formed by part-off tool 33.
  • the front end cap 39 may have a boring tool 40 to form an internal bore thereof and grooves 41 and 43 may be formed by grooving tool 42.
  • the invention also includes within its scope the casting per se.
