Abstract
The present invention belongs to the field of metallurgical machine technology, and is especially one centrifugal casting machine set to cast metal melt centrifugally to inner wall of the work piece. The centrifugal casting machine set includes a metal melting furnace, a discharging and casting mechanism, a centrifugal casting machine, etc. It features the metal melting furnace on one pedestal with walking mechanism, the pedestal with material bin and casting conduct pipe, the centrifugal casting machine with two conic forcers, two motors on the frame to drive two forcers to rotate synchronously in the same direction, and two locking hydraulic cylinders below the movable frame. The present invention has the advantages of integrated metal melting furnace and centrifugal casting machine, small production space, high production efficiency, low heat loss and high product quality.
Description
Technical field:
The invention belongs to technical field of metallurgical machinery, be specifically related to a kind of metal liquid that will melt and be cast to spun casting unit on the annular work piece inwall by centrifugal action.
Background technology
At present, prior art is when the metal liquid that has melted toward annular work piece such as bearing inner surface top casting, after often solid metallic being melted in well-type electric furnace, with lifting machine liquation is taken out from stove again and be transported to cast and be poured in the hopper, by the cast conduit metal liquid is delivered in the annular work piece that is rotated by the high speed of the monolateral driving of separate unit motor drives again and carried out spun casting, as shown in Figure 1.
The shortcoming that prior art exists is:
(1) the metal molten stove separates with casting machine, and is far away to the casting distance from discharging, transports inconvenience by lifting machine, and melt temperature is descended, and both wastes time, and lost heat again.
(2) hopper and cast conduit are fixed on the frame in the prior art.Like this, pour point is fixed, and this comes lecture to produce the casting thickness non-uniform phenomenon to long workpiece, influence casting quality.
(3) in the prior art, the shape of the top of two in the casting machine is with the level flat discoid, and periphery has flange.This workpiece to different-diameter just needs to change the top of different-diameter, has increased the quantity of spare part, also can influence production efficiency.
(4) be to drive a top rotation by the monolateral driving of separate unit motor in the prior art, frictionally drives workpiece and the rotation together of another top.This structure is easy to generate skidding, influence casting quality.
(5) the locking sliding seat has only a locking hydraulic locking cylinder in the prior art, is easy to generate lock in the practice and does not tightly reach phenomenons such as coupling mechanism force skewness, can influence locking effect.
Summary of the invention:
The object of the invention provides a kind of spun casting unit of the new construction that has improved, and can overcome the shortcoming that prior art exists effectively.
The present invention is achieved in that it comprises metal molten stove, discharging and cast mechanism, centrifugal casting machine etc.It is characterized in that described metal molten stove is placed in the bottom and is equipped with on the base of walking mechanism, receiving hopper and cast conduit are installed on base, two tops were cone shapes about described centrifugal casting machine is characterized in that, learnt that by experiment the garden cone angle is 30 °～160 °.About two drive two cone shapes tops by transmission mechanism and make the motor mounting of synchronous, equidirectional rotation on the relevant position of frame.Below the locking sliding seat, on the frame, the tight hydraulic cylinder of two stand locks is installed side by side.
During production, workpiece is packed between two tops, advance by the PF cylinder pressure workpiece is clamped, by the tight hydraulic cylinder of two stand locks sliding seat is fixed again.Do two cone shapes top and the rotation at a high speed of workpiece do about synchronous homodromal motor drives for two about starting then, by discharge nozzle metal liquid is poured into receiving hopper by the metal molten stove then, by the cast conduit metal liquid is injected the workpiece of rotation at a high speed again, carry out spun casting.Walking before and after melting furnace is done can be regulated cast conduit move left and right, makes casting more even.
Advantage of the present invention and good effect have:
1. metal molten stove and centrifugal casting machine are connected as a single entity, make operation convenient, both can save time, avoided thermal loss again, also can improve the casting quality.
2. adopt the metal molten stove that to walk, both can make easy to operately, can make casting evenly again, improved product quality.
3. adopt both sides cone shape top transmission, the adaptability of holding workpiece is improved, both can save spare part quantity, can enhance productivity again.
4. adopt the locking of bilateral driving of left and right sides two motors and double hydraulic cylinder, can make production process solid and reliable, skid in having avoided producing and lock tight phenomenon.

The specific embodiment:
As shown in Figure 3, metal molten stove 30 be installed in the bottom be equipped with road wheel, can be on the base 31 that moves on the guide rail 32, receiving hopper 4 and cast conduit 1 are installed on the base 31, two cone shape tops 25 and 26 are installed on the centrifugal casting machine, the garden cone angle is α=65 °, drive the motor 7 and 28 of doing synchronously, rotating in the same way in cone shape top 25 and 26 by belt transmission 5 and 29 respectively and be installed on the frame 1, below sliding seat 15, locking hydraulic cylinder 27 is installed side by side with locking hydraulic cylinder 11.During production workpiece 9 is packed between the two cone shapes top 25 and 26, advance top 26 to move by PF cylinder pressure 14 again, workpiece 9 is clamped.By locking hydraulic cylinder 11 and 27 sliding seat 15 is fixing, start again motor 7 and 28 by belt transmission 5 and 29 drive top 25 and 26 and workpiece 9 do rotation at a high speed.Molten metal is poured in the receiving hopper 4 by discharge nozzle 33 by metal molten stove 30 then, by cast conduit 1 metal liquid is poured in the workpiece 9 of rotation at a high speed again, carry out spun casting.Can also regulate the position of cast conduit 1 by the walking mechanism of metal molten stove 30 bottoms, make casting more even.
