Description

one

The invention relates to a foundry, namely, to centrifugal casting of shaped castings of small and medium weight in smelting and melting installations having centrifugal tables of large diameters.

The purpose of the invention is to expand the range of castings.

The drawing shows the structure of the device.

The device consists of a filling chamber 1, a centrifugal table made of a central disk 2 and concentrically arranged in one another rings 3 and 4.

On the centrifugal table, containers 5 with casting molds 6 are installed, which are connected to metal receivers 7–9 and ring-casing channels 10. Mold 6 in containers 5 installed on one part of the centrifugal table have one common metal receiver.

Above the metal receivers installed common drain chute 11. The centrifugal table has drives 12 with gears, the Device operates as follows.

Before pouring the metal into the casting molds, the disk 2 and the rings 3 and 4 of the centrifugal table with the coitaker 5, the mold 6 and the central 7 and the ring 8 and 9 metal receivers are placed in rotation. Moreover, the angular rotational speeds are chosen so that

The centrifugal forces acting during the rotation of the central disk and individual rings on the liquid metal were optimal. If necessary for

reducing the centrifugal device's vibration; the drive design allows part of the rings to rotate in the opposite direction. After the required rotational speeds have been established, the liquid metal is poured into the channel 11. Through the holes in the channel, the metal enters the rotating central and ring metal receivers and then through the holes in them through the casting channels 10 into the molds. After the metal crystallizes in the molds, the centrifugal device stops.

This device allows the use of a central disk and concentric rings of a centrifugal table in various ways, for example: when they all rotate at the same angular speed as one table; when rings 3 and A rotate

with one, and the central disk 2 with a different angular velocity; when the central disk 2 and the rings 3 and 4 rotate at different angular speeds. This makes this device universal and allows casting on it both small and large size castings.

The use of the device allows to increase the load factor of equipment intended for the production of large casting.
