Blade mold manufacturing system and blade mold manufacturing method

Abstract

The invention provides a vane die manufacturing system and a vane die manufacturing method. The system comprises a sectional vane die mold base, a 3D printer and an accompanying feeding trolley, wherein the sectional vane die mold base is located in the printing scope of the 3D printer, the 3D printer is used for printing female mold-type vane die cavities in layers on the sectional vane die mold base, and the accompanying feeding trolley is connected with a feed box the 3D printer and used for supplementing a material to the feed box of the 3D printer. According to the invention, through printing of female mold-type vane die cavities in layers on the sectional vane die mold base, cost for preparation of vane male molds is saved, manufacturing precision of a large vane die can be substantially improved, and manufacturing cost for the large vane die can be reduced; since the die cavities are integrally printed and molded, the sections of the die can be increased, the length of each section of the die can be decreased, the phenomena of cracks and air leakage of vane dies caused by sectioning of the die in the process of die production can be thoroughly prevented, and vane quality is improved.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a blade mold manufacturing system and a blade mold manufacturing method. Background technique [0002] With the increase in the size of the impellers of wind turbines, the length of the blades continues to increase. The length of the existing blades has reached tens of meters, and the weight has reached more than ten to ten tons, which has gradually increased the transportation cost and difficulty of the blades, especially in mountainous and hilly areas. The difficulty of transportation and the cost of opening transportation channels will increase greatly. In order to solve the problem of blade transportation, blade manufacturers currently move blade manufacturing to the wind field or near the wind field, and some manufacturers also divide the blade mold into sections for the transportation of the mold. [0003] At present, large blade molds are generally made of FRP materials....

AI Technical Summary

Problems solved by technology

In the mold making, because the FRP mold undergoes the process of turning the male mold into the female mold, handling, and fixing the female mold, and the size of the mold is relatively large, it is difficult to guarantee the accuracy of the blade mold cavity. After being spliced ​​again, it is easy to cause cracks in the splicing part during the repeated heating and cooling process of the mold, resulting in air leakage of the female mold during vacuum suction
