AI Technical Summary
Existing methods for forming conical parts have defects such as porosity, cracks, and slag inclusions. The process is complex, making it difficult to process large-diameter, thick-walled parts. Furthermore, frequent equipment and mold replacements and poor repeatability result in poor workpiece quality.
The 5A06 aluminum alloy thick-walled conical structure is spun into a shape using a spinning method that includes hot spinning and optimized annealing processes. The spinning process is carried out in two passes using a CNC open spinning machine and a spray gun for local heating, combined with annealing to control deformation and precision.
It has achieved high-precision forming of large-diameter, thick-walled conical structures, reducing mold costs and processing cycles, and improving workpiece quality and production efficiency.
