AI Technical Summary

Technical Problem

The existing blade final forging die has uneven metal distribution during forming, resulting in excessive flash, rapid local wear of the die, and low material utilization.

Method used

By calculating the parameters of the blade part design drawing, the cavity shape and size of the final forging die are designed, so that the metal material is gradually distributed as needed, avoiding the design of flash grooves. The mold parting surface is generated by 3D modeling software to ensure that the metal material is neither insufficient nor excessive during the forming process.

Benefits of technology

It achieves efficient utilization of metal materials, avoids waste of raw materials and blade deformation, improves mold life and blade dimensional stability, and achieves a metal raw material utilization rate of over 80%.

Abstract

The application discloses a kind of final forging forming die of blade and design method, including the following steps, according to the blade part design drawing provided blade profile section coordinate parameter, calculate the blade profile section coordinate parameter after adding allowance;According to the blade profile section coordinate parameter after adding allowance and balance angle, the coordinate parameter of the blade profile section of final forging forming die is calculated;The coordinate parameter of the blade profile section of final forging forming die calculated is imported into three-dimensional modeling design software, the shape of the blade body part of final forging is generated;Blade tenon and process chuck are added to the blade body both ends obtained by final forging;With the blade profile center line of the blade profile section of final forging as parting line, the parting surface of final forging forming die is constructed, and final forging forming die is designed according to parting surface.No flash groove is needed for final forging forming die to accommodate excess metal, metal material is gradually deformed "on demand" distribution, and final forging does not need to be trimmed, which will not cause raw material waste and will not cause blade deformation.
