Abstract

The invention relates to an aluminum alloy cold forging device, in particular to an aluminum alloy propeller cold forging device. The technical problem to be solved by the present invention is to provide an aluminum alloy propeller cold forging device. An aluminum alloy propeller cold forging device, including a mounting frame, a controller, a transmission belt mechanism, a micro motor, a step-stop mechanism, a blade bending mechanism and an electromagnetic pick-and-place mechanism; Welding; the left part of the bottom end of the installation frame is welded with the transmission belt mechanism. The invention achieves the bending of a single blade of a straight-blade aluminum alloy propeller, so that the blade undergoes a curve change, so that the curve of the blade conforms to a fluid structure, and at the same time increases the air intake of the blade and the propulsion of the propeller. At the same time, the position of the straight-blade aluminum alloy propeller is limited so that it is not easy to shift during twisting, preventing the straight-blade aluminum alloy propeller from being lost during the transfer process and causing injury to the operator.

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...
