Casting equipment for automatically flattening inner wall of pipe based on centrifugal force

Abstract

The invention relates to the technical field of centrifugal casting, and discloses casting equipment for automatically flattening the inner wall of a pipe based on centrifugal force. The casting equipment for automatically flattening the inner wall of a pipe based on centrifugal force comprises a frame body, the top of the frame body is rotatably connected with a rotating frame, the left end of the rotating frame is in transmission connection with a first motor, the interior of the left side of the rotating frame is slidably connected with a hinge block, and a first connecting rod is hinged to the middle of the hinge block; a push block is hinged to the end, close to the center of the rotating frame, of the second connecting rod. According to the casting equipment for automatically flattening the inner wall of the pipe based on the centrifugal force, a second centrifugal block abuts against a contact point on the basis of the centrifugal force effect, an electromagnet attracts a first magnetic block to enable annular blocks to be unfolded mutually to extrude the inner hole face of a casting, the first centrifugal blocks are far away from each other under the centrifugal force effect, a push block moves leftwards to compress a first spring, and a first motor is closed after the casting is formed; a pushing block pushes the casting rightwards under the elastic action of the first spring, and appearance damage of the casting in the casting taking-out process is avoided.

Description

technical field [0001] The invention relates to the technical field of centrifugal casting, in particular to casting equipment for automatically flattening the inner wall of a pipe based on centrifugal force. Background technique [0002] Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold to fill the mold and form castings under the action of centrifugal force. The feature of centrifugal casting is that the molten metal is filled and solidified under the action of centrifugal force. The feeding effect is good, the casting structure is dense, and the mechanical properties are good. Therefore, for some specific shapes such as tubular castings, centrifugal casting is a material-saving, energy-saving and high-efficiency process. However, centrifugal casting also has disadvantages. The mold rotates at high speed, and the molten metal rotates with the cavity. When the liquid solidifies, the liquid on the side of the inner hole ...
