Abstract
The invention discloses a kind of involute elbow chute, which includes straightway and bending segment, and one end of bending segment is connected to the discharge end of straightway, and the other end is connected to centrifugation casting machine；Wherein, bending segment is involute bending, and tangent line of the bending segment close to one end of straightway is parallel with straightway, and 18-25 ° of formation enters modular angle between the tangent line and straightway of one end far from straightway.The involute elbow chute has obvious buffer function to molten iron liquid impact force in entrance triangular angular situation identical with straight flange angie type, and in addition to this, involute can be further increased modular angle degree is entered and molten iron fluctuation is also less than traditional straight flange angle elbow.
Description
Technical field
The present invention relates to centrifuge casting craft devices, more particularly to involute elbow chute.
Background technique
Chute is the important equipment for being used to import molten iron centrifugation in centrifuge casting craft, and it is steady to enter mould for raising molten iron
The preshoot of molten iron inertia is reduced, launder outlet generally uses 20 ° or so of straight flange elbow, this technique has used many decades.But
In use because of molten iron inertia impact, at elbow turning because angle stops, often result in molten iron wave, caused by consequence
It is to be unevenly distributed even formation corrugated pipes after molten iron enters mould.
Summary of the invention
The object of the present invention is to provide a kind of involute elbow chute, the involute elbow chute entrance triangular angular with
There is obvious buffer function to molten iron liquid impact force in the identical situation of straight flange angie type, in addition to this, involute can will enter mould
Angle further increases and molten iron fluctuation is also less than traditional straight flange angle elbow.
To achieve the goals above, the present invention provides a kind of involute elbow chute, which includes
Straightway and bending segment, one end of the bending segment are connected to the discharge end of the straightway, and the other end is connected to centrifugation and pours
Machine；Wherein, the bending segment is involute bending, and the bending segment is close to the tangent line of one end of the straightway and described straight
Line segment is parallel, and 18-25 ° of formation enters modular angle between the tangent line and the straightway of one end far from the straightway.
Preferably, it is described enter modular angle angle be 19-23 °.
Preferably, it is described enter modular angle angle be 21-23 °.
Preferably, the bending segment is the continuous kink of curve.
Preferably, the bending segment is continuous straight line bends.
Preferably, multiple wave resistance protrusions are connected on the inside cell wall of the bending segment.
Preferably, the wave resistance protrusion is cylindrical protrusions.
According to the above technical scheme, one end of heretofore described bending segment is connected to the discharge end of the straightway, separately
One end is connected to centrifugation casting machine；Wherein, the bending segment is involute bending, and the bending segment is close to the straightway
The tangent line of one end is parallel with the straightway, is formed between the tangent line and the straightway of one end far from the straightway
18-25 ° enters modular angle.The involute elbow chute is in entrance triangular angular situation identical with straight flange angie type to molten iron liquid
Impact force has obvious buffer function, and in addition to this, involute can will enter that modular angle degree further increases and molten iron fluctuation is also small
In traditional straight flange angle elbow.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
