DEVICE FOR LUBRICATING MOULDS Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: device has bridge crane mounted over train with moulds, oil atomizer, crane mounted truck for transverse replacement, oil atomizer rod ajoint to carrier, oil atomizer rod movement mechanism. Carrier is mounted on rollers for movement along vertical rail fastened to truck. Oil atomizer rod movement mechanism has cable guiding blocks, drum-type winch with electric motor and worm reducer. Device is provided with reciprocating spring with adjusting screw mounted on a cable between oil atomizer rod and winch drum, steady magnets and magnet controlled contacts mounted on oil atomizer rod rail and diamagnetic flags fixed on oil atomizer rod. When oil atomizer rod drops and brakes, reciprocating spring acumulates power and after oil atomizer rod stops completely reciprocating spring coordinates acumulated power with drum winch power, directed to rod lifting after electric motor is turned on lifting. Reciprocated spring and winch forces are coordinated with the help of magnet controlled contacts. In this case retention of rod with oil atomizer in lower part of mould and power consumption are minimal. Mould lubrication results even. EFFECT: improved design. 3 dwg
