Vertical type centrifugal casting device of thin-wall alloy steel

Abstract

The invention provides a vertical type centrifugal casting device of thin-wall alloy steel, belonging to a centrifugal casting device and in particular to a device for casting a flat thin-wall alloy steel cast with complex shape. The device is characterized in that an electromotor is axially, vertically and fixedly arranged on a base; a main shaft is vertically and fixedly on a work table board and a fixed board of a stander; a shaft of the electromotor is connected with a belt wheel of the main shaft through a driving belt; a casting mould is vertically inserted into a rotating drum and is fixed by heat-preserving fiber in a filling way; the rotating drum is clamped on a chuck; the axes of the casting mould, the rotating drum and the chuck and the axes of the main shaft are on the same straight line; the work table board on the stander is provided with a movable enclosing cover which encloses around the rotating drum; the base is provided with a footboard which is connected with an electromagnetic brake; an operation faceplate is arranged on the enclosing cover and is electrically connected with the electromotor, an electric source and the electromagnetic brake. The device has the advantages of novel structure, compactness, reliable running, multiple one-step molding casts, high production efficiency, easy manufacture, convenient installation and maintenance, good quality of the casts, high yield, lower material and power consumption and high practical applicability.

Description

technical field [0001] The invention belongs to a metal centrifugal casting device, in particular to a casting device for casting flat thin-walled alloy steel castings with complex shapes. Background technique [0002] The exhaust impeller of alloy steel turbocharger has a thin wall, only 0.5 mm in thickness, complex shape, dense and uniform internal structure, good surface quality, good hardness, elasticity, strength and rigidity. Therefore, the requirements for the temperature, fluidity and casting pressure of molten steel are very strict when casting this impeller. "A Centrifugal Casting Device" (ZL03271932.9) disclosed by the China Intellectual Property Office only discloses that the device is composed of a central shaft, a turntable and a casting mold connected. The casting mold has a main runner, a secondary runner, and a casting cavity. , exhaust holes, and the central axis of the main runner is consistent with the center of the central rotating shaft. "A Centrifuga...
