Abstract:
Apparatus for cleaning castings comprising a cleaning cabinet,a rotary clamping device in the cabinet rotatably clamping a casting to be cleaned, means for rotating said clamping device, an elongate lance projecting into said cabinet and having a high pressure nozzle at its inner end, means connecting the lance to a source of high pressure water for producing a high pressure jet of water directed against a casting to be cleaned, means mounting said lance for pivotal and rotary movement relative to the cabinet, first and second lance pivoting means connected with said lance and each being rapidly actuated to produce rapid pivotal movement of the lance, the actuation time and the magnitude of pivotal movement of the lance produced by said first lance pivoting means differing from that of the second lance pivoting means, programmable control means operatively connected to said first and second lance pivoting means for selectively controlling the rapid actuation times of the first and second lance pivoting means, said control means being programmable to the desired casting height and cleaning cycle time, said first and second lance pivoting means when actuated by said control means producing random movement of the lance relative to a casting to be cleaned for effecting rapid cleaning and programmable to the desired casting height and cleaning cycle time of a casting.
