Abstract
The utility model belongs to a centrifugal casting machine, which is a novel centrifugal casting machine that a main shaft is designed into a double-layer hollow structure, and cold water passes through a main shaft of a strong refrigerating machine from a hollow part. A main shaft structure uses the double-layer hollow structure. Both ends of the main shaft are supported by bearings. One end of the main shaft is provided with a belt wheel for importing power, and a casting mould can be arranged on a main shaft flange on the other end. A main shaft of the double-layer hollow structure can be cooled by watering. The utility model can retain the main shaft and the bearings to operate under normal temperature without the influence of high temperature casts and expansion and dead clamping phenomena; the novel centrifugal casting machine does not need to be specially cooled by intermittent operation, and can realize the running in high speed of the main shaft.
Description
The utility model belongs to centrifugal casting machinery, is its main shaft is designed to double-deck cancelled structure, and cold water cools off the novel centrifugal casting machine of main shaft by pressure from abdomen.
The centrifugal casting machine that uses at present all is that main shaft is hollow shaft or solid shafting, support by two bearings, one end is imported power by belt pulley, the other end has a ring flange, mold can be installed on ring flange, by the high speed rotating of main shaft, make the metal under the molten state of injecting in the mould under centrifugal action, be distributed in mould inner surface during work, reach the purpose of casting.The ubiquitous problem of this structure is: owing to inject high temperature melting state metal down in the mould, high temperature can pass to the bearing of main shaft and spindle nose very soon, and main shaft will produce distortion, and bearing swollen the rising that will be heated causes and vibrate and the bearing stuck phenomenon.In order to keep bearing not stuck, can only be interrupted work, be interrupted cooling.Therefore bring production efficiency low, equipment life is short, because the distortion of main shaft, main shaft raising speed is restricted.
The purpose of this utility model is, proposes the influence that a kind of main shaft and bearing are not subjected to foundry goods high temperature, and main shaft is indeformable, and not swollen the rising of bearing can be not stuck, production efficiency height, the centrifugal casting machine that service life of equipment is long.
This centrifugal casting machine of casting manipulations that is applicable to is characterized in that: the structure of its machine shaft is to have adopted double-deck cancelled structure, two ends are supported by bearing, one end is equipped with belt wheel and is used for importing into power, on the one end spindle flange mold can be installed, the main shaft core of double-deck cancelled structure is equipped with knock-pin and is used in when ejecting cast blank and uses, the belly of double-deck cancelled structure main shaft, at one end lead to into cooling water, cooling water flows to the other end gradually in the empty stomach chamber, throw away by centrifugal force from the aperture of the other end, this process reaches forces cooling to main shaft, has also avoided the intensification of bearing simultaneously.
The utility model has the advantages that: can keep main shaft and bearing under normal temperature, to work, be not subjected to the influence of high temperature foundry goods, main shaft does not have high temperature deformation, bearing does not expand, stuck phenomenon can not occur, need not be interrupted work, be interrupted cooling specially, main shaft and bearing long service life can realize that main shaft runs up.
Description of drawings: figure is the main shaft structure chart of water-cooled centrifugal casting machine host machine part on an empty stomach, among the figure, 1 push rod, 2 springs, 3 belt wheels, 4 bearing caps, 5 bearing blocks, 6 left bearings, 7 bolts, 8 are main shaft, 9 braked wheels, 10 feed pipes, 11 water shutoffs lid, 12 bearing caps, 13 right bearings, 14 bearing blocks, 15 dash bearing caps, 16 bolts, 17 bolts, 18 top boards, 19 moulds, 20 supports, 21 bolts, 22 sealing rings, 23 bolts on an empty stomach.Main shaft 8 left ends are by left bearing 6 supportings on an empty stomach, left bearing 6 is installed on the support 20 by bearing block 5 and bearing cap 4, right-hand member is by right bearing 13 supportings, right bearing 13 is by bearing block 14, bearing cap 12 and dash bearing cap 15 are installed on the support 20, belt wheel 3 is fixed in the left end of main shaft 8 on an empty stomach, braked wheel 9 is fixed in the middle of the empty stomach main shaft 8, water shutoff lid 11 is fixed on the bearing cap 12 by bolt 23, sealing ring 22 is equipped with at water shutoff lid cavity two ends, mould 19 is installed on the ring flange of empty stomach main shaft right-hand member, and push rod 1 and spring 2 are contained in main shaft 8 cores on an empty stomach, and push pedal 18 is fixed in push rod 1 right-hand member.
Now in conjunction with the accompanying drawings the operation principle of the present utility model and the course of work are described in detail.This main frame drives empty stomach main shaft 8 by motor by belt wheel 3 and mould 19 runs up, at this moment the metal that has melted injects in the mould 19, the metal that has melted closely is distributed under action of centrifugal force on the mould inner cylinder, behind the cooling curing, stops motor power, with brake block friction catch wheel 9, main shaft is stopped, promote push rod 1 by ejecting mechanism at A point then and move right, lean on push pedal 18 that blank is released, push rod resets by spring 2, finishes a process.In this process work, its cooling principle and process are: running water is injected in the cavity of water shutoff lid 11 by feed pipe 10 by the aperture B on the water shutoff lid 11, inject in the empty stomach of empty stomach main shaft 8 by empty stomach main shaft several apertures C of 8 gardens on week again, water also is subjected to action of centrifugal force in empty stomach, under centrifugal action, will throw out by several apertures D of empty stomach main shaft right-hand member garden on week, the water that throws away is under the control of dash bearing cap 15, can only lean on following hole E to spill out, flow to sewer, this process reaches the purpose of cooling main shaft.
