Embodiment Construction

[0023] use as Figure 1-Figure 5 A uniform feeding centrifugal casting method according to an embodiment of the present invention is described as follows.

[0024] Such as Figure 1 to Figure 3 Shown, the centrifugal casting method of a kind of uniform feed of the present invention, this method comprises the steps:

[0025] S1: A filter is installed inside the feeding pipe of the centrifugal casting equipment, and the filter is used to filter the molten metal; the molten metal is introduced into the feeding pipe, and the molten metal enters the feeding pipe, and the auger rotates to feed, and the auger rotates During the process, the first bevel gear is driven to rotate, thereby driving the second bevel gear and the rotating shaft to rotate. The ball swings outward under the action of centrifugal force. After the ball rotates to the maximum angle, it keeps rotating and enters the feeding tube. Stir the metal liquid to prevent the metal liquid from clogging inside the feeding...

Abstract

The invention belongs to the technical field of centrifugal casting, and specifically relates to a centrifugal casting method with uniform feeding. The method includes the following steps: a first bevel gear is fixedly connected to the outside of the auger of the centrifugal casting equipment, and the top of the first bevel gear meshes with the A second bevel gear is connected, and the top of the second bevel gear is fixedly connected with a rotating shaft, and the top of the rotating shaft extends to the inside of the feeding tube; a filter screen is arranged inside the feeding tube, and the top of the filter screen is fixedly connected with two left and right symmetrical settings. The fixed rod; the filtered metal liquid is introduced into the casting roll through the feeding pipe, the casting is formed, and the fan blade rotates after forming to generate wind along the radial direction of the casting roll, which exerts wind pressure on the free surface of the casting to eliminate air bubbles and looseness on the free surface of the casting ; After the air bubbles and porosity on the free surface of the casting are eliminated, the casting waits for cooling, the fan blade changes the angle, and the rotation of the fan blade generates wind along the axial direction of the casting roll to accelerate cooling; after the casting is cooled, the casting is stripped to complete the casting of the casting.

Description

technical field [0001] The invention belongs to the technical field of centrifugal casting, in particular to a centrifugal casting method with uniform feeding. Background technique [0002] The existing centrifugal casting device fills the mold with liquid metal under the action of centrifugal force. The metal feeding effect of the casting casted by the centrifugal casting device is good, and the free surface is used to generate a cylinder to form a ring-shaped casting, which can save the core and gating system , saving labor, saving materials, reducing the cost of castings. The characteristics of centrifugal casting are that the molten metal is filled and solidified under the action of centrifugal force, the effect of metal feeding is good, the structure of the casting is dense, the mechanical performance is good, and the casting of hollow castings does not need a riser. The utilization rate of metal can be greatly improved, but the existing centrifugal casting machine is n...
