Abstract

The invention discloses a method for producing and molding an axial flow fan impeller, comprising the following steps: a. Raw material processing: putting the raw materials required for producing blades into a mixer for raw material mixing; b. Injection molding: mixing the raw materials Put it into the injection molding machine and get the blades by injection molding; c. Component assembly: assemble the produced blades on the impeller to obtain the finished product; d. Finished product cleaning: put the assembled finished impeller into the clean water tank for cleaning, and remove the blades Dust and other impurities on the surface. The invention improves the raw material mixing effect and raw material processing efficiency under the action of the mixer, improves the entire blade processing technology, and improves the overall processing efficiency of the blade, so as to quickly complete the production of the blade after modeling, increase the output of the blade, and complete the amount of the blade Produce.

Description

technical field [0001] The invention belongs to the technical field of 3D modeling of blades, and in particular relates to a production and molding method for an axial flow fan impeller. Background technique [0002] With the development of computer technology, the three-dimensional model of the impeller will be used to analyze the strength, stiffness, and mode when designing the impeller. The efficiency and accuracy of impeller modeling have a certain impact on the design. [0003] For 4-73 impeller modeling, the commonly used method is to model through two sections A-A and B-B. The steps to establish the blade part are as follows: draw the A-A and B-B cross-sectional sketches respectively —> surface lofting —> extension surface —> closed surface —> clipping surface —> thickening —> shelling and other steps, the whole process has more steps and several steps There are often problems during generation, or the software takes a long time to calculate; the ra...
