AI Technical Summary

Technical Problem

The current engine blade manufacturing process suffers from low work efficiency, poor product quality, and low material utilization. In particular, when manually stacking composite material blades, defects such as incorrect placement of the blade strips, wrinkles, and adhesion are prone to occur, resulting in long production time, unstable product quality, and serious material waste.

Method used

The blade mold is made of dense array fixtures and shaping tooling. After pre-deformation, the blade strips are automatically laid up. Articulated robots and vision systems are used to achieve precise shaping and fitting of the blade strips. The extrusion head ensures that the blade strips are tightly fitted to the mold surface.

Benefits of technology

It has enabled automated stacking of engine blades, improving work efficiency, ensuring product quality, reducing material waste, and enhancing production efficiency and forming effect.

Abstract

This invention relates to a method for laying up blades of a dense array variable surface engine. The deformable end of the dense array fixture is bonded to the surface of the blade mold and deformed, maintaining its deformed state. The deformable end of the dense array fixture, in its deformed state, is bonded to the deformable end of a shaping fixture, which deforms and maintains its deformed state. The deformable end of the dense array fixture returns to a flat end face, and under the action of an external air source, the deformable end horizontally lifts the blade strip. The end face of the dense array fixture holding the blade strip is bonded to the deformable end of the shaping fixture, and the deformable end of the dense array fixture deforms, causing the blade strip located between the deformable ends of the dense array fixture and the shaping fixture to deform. The dense array fixture transfers the deformed blade strip onto the surface of the blade mold. This achieves pre-deformation of the blade strip before it is laid up on the blade mold, not only realizing automated laying but also greatly improving and ensuring laying efficiency and effectiveness.
