Abstract

The invention relates to aluminum alloy cold forging, in particular to an aluminum alloy propeller cold forging device. The aluminum alloy propeller cold forging device provided by the invention is used for solving the technical problems. The aluminum alloy propeller cold forging device comprises a mounting frame, a controller, a driving belt mechanism, a micro motor, an intermittent stalling mechanism, a propeller blade bending rotating mechanism and an electromagnetic taking and placing mechanism. The right middle portion of the bottom end of the mounting frame is welded to the controller. The left portion of the inner bottom end of the mounting frame is welded to the driving belt mechanism. The aluminum alloy propeller cold forging device achieves the bending effect on single propellerblades of a straight-blade aluminum alloy propeller to change curves of the blades, so that the curves of the propeller blades conform to the fluidics structure. Meanwhile, the air inlet volume of theblades is increased, and the propelling amount of the propeller is increased. Meanwhile, the position of the straight-blade aluminum alloy propeller is limited, so that the straight-blade aluminum alloy propeller is not prone to displacement in twisting. The situation that the straight-blade aluminum alloy propeller is lost in the transfer process and hurts an operator is avoided.

Description

technical field [0001] The invention relates to an aluminum alloy cold forging device, in particular to an aluminum alloy propeller cold forging device. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A marine propeller. There are many types of propellers, and they are widely used, such as propellers for airplanes and ships. [0003] Prior art Chinese patent CN108838372A discloses a copper alloy propeller for a large ship in view of the low control precision of the existing differential pressure casting pressurization curve, which makes it difficult to ensure the smooth filling of propeller hub castings with uneven structural wall thickness. Non-linear pressurization method for propeller hub differential pressure cast...
