Description
Technical field
The present invention relates in cylinder jacket processing technique equipment technology field, be specifically related to the centrifugal of a kind of cylinder jacket of diesel engine
Casting system.
Background technology
Centrifugal casting machine is that one utilizes centrifugal force, and molten metal enters in the type tube of high speed rotating, under centrifugal action
Cooling, molding are to obtain the Casting Equipment of metal casting.Wherein, horizontal casting machine is a kind of typical centrifugal casting machine, mainly
For pouring into a mould various tubular cast.Existing horizontal casting machine primary structure is for including horizontally disposed type tube, by becoming below type tube
Support roller supporting reliable support roller to arranging are rotated, and support roller is connected with power set and leans on it to drive, the internal two ends of type tube
Place is provided with the end cap of annular.
Existing centrifugal casting system has some problem following:
Wherein the centrifugal rotational power of type tube is mainly provided by the frictional force between type tube and support roller, between type tube and support roller is
Linear contact lay, linear contact lay Area comparison is little, it is provided that frictional force smaller, the speed of the centrifugal motion of type tube the most of the prior art
Degree is limited, during as shaping speed demand that rotating speed can not meet pipe fitting occur.In casting production process, watering in type tube
Casting liquid will overflow the end cap of type tube both sides because of centrifugal force and spatter steel or bleed-out not, and, of the prior art
Type tube is when high-speed rotation, and axial constraint is less often jumps even without, type tube on support roller, and fluctuation is relatively big, occurs one
Fixed impact, makes molten steel overflow type tube end cap the most unavoidably and spatters steel.Liquid casting of even casting in operating process is excessive or does exercises
Make human users to rock improper causing, its huge heat energy of molten steel and the kinetic energy impact under centrifugal action, also result in and send out
Steel or bleed-out accident are spattered in life.
And at present in centrifugal casting technique, the internal two ends of type tube use end cap closure, prevent molten metal splashing from solidifying
Tube drawing is affected at type tube two ends.The fixing of end cap typically uses pin at present, loads and unloads use and beat mode, to type tube in production
There is very macrolesion, and owing to beaing vibration, it is also possible to destroy the balance of type tube and affect product quality.So utilizing pin solid
Fixed end lid has safety coefficient big, inconvenient operation low, destructive, affects the shortcomings such as production efficiency.
Pipe drawing device, cleaning plant and spray equipment are the most independent moving trolleys, pipe drawing device, cleaning plant and
Spray equipment completes respective operation, swaps handing-over and enters next operation sequence, needs to spend the longer time, and operation is multiple
Miscellaneous, the production cycle is long, inefficiency, and in operation, in addition it is also necessary to spend substantial amounts of human and material resources, production cost
Height, occupation area of equipment is big.
Molten metal bath is mainly poured in die cavity by the centrifugal casting of prior art by pouring ladle and chute, then enters
Next step casting process of row, but existing cast operation there is problems in that one, has bigger weight due to molten metal,
Expending muscle power, and the Ramp rates of wayward pouring ladle during artificial cast, when toppling over speed and being too fast, molten metal is easily from type
Chamber is overflowed；Three, for horizontal type centrifugal-casting, the chute of prior art is directly watered by the horizontal part of insert type intracavity
Note, molten metal can only flow out from the end of horizontal part, and some fixing point of molten metal intense impact die cavity makes the anticorrosion of this point
Damage of material.
