Stacked type propeller manufacturing method

Abstract

The invention provides a stacked type propeller manufacturing method. The method comprises the following steps that a three-dimensional model diagram of a propeller is built through computer-assisted software; format conversion is carried out on the three-dimensional model diagram of the propeller to generate hierarchical data of the propeller, and the hierarchical data is input into identifiable equipment; the data of materials selected for manufacturing the propeller is input into the identifiable equipment; supporting bodies of the propeller are provided for the identifiable equipment; the identifiable equipment is used for stacking the supporting bodies for providing the propeller layer by layer according to the sequence from bottom to top on the basis of the obtained hierarchical data and the data of the selected materials, and a base body of the propeller is output; and the base body of the propeller is post-processed to obtain the finished product. According to the method, various types of propellers can be manufactured in a layer-by-layer stacking mode according to the requirements of a designer, the autonomy of the designer and product variety are greatly enhanced, the manufacturing cost is reduced, and market requirements are met.

Description

technical field [0001] The invention belongs to the propeller manufacturing process, in particular to a method for manufacturing a stacked propeller. Background technique [0002] A propeller is a device that converts the rotational power of the engine into propulsion or lift by the rotation of the blades. It consists of multiple blades and a central hub on which the blades are mounted like a twisted, slender wing, to which the motor shaft is connected and drives it to rotate. Propellers can be divided into many types and are widely used, such as propulsion devices for aircraft and ships. [0003] The ship propeller is one of the main power equipment of the hull, which converts the kinetic energy of the hull into the driving force of the ship, so the manufacturing quality and process of the propeller are very important. The main manufacturing material of ship propellers is metal, and its traditional manufacturing processes include mold molding, metal casting, blank process...

AI Technical Summary

Problems solved by technology

With the continuous expansion of the manufacturing scale of ship propellers, it is more and more difficult to adopt a one-time casting process, with low controllability and huge cost. The traditional manufacturing process greatly limits the development of ship propellers.
