AI Technical Summary

Technical Problem

Existing technologies for preparing bent Y-shaped aluminum alloy forgings suffer from serious material waste and uneven deformation, especially in free forging and simple die forging processes, resulting in low material utilization and poor forging stability.

Method used

A forging die is designed, including an upper die and a lower die. Process bosses are provided on the lower die to guide the deformation of the billet and ensure uniformity. By adding process bosses at key positions of the die, the surface of the billet contacts first and flows outwards. The conformal design reduces the weight of the forging blank.

Benefits of technology

It significantly reduces the weight of forging blanks, improves the dimensional consistency of billets and the stability of forgings, reduces forging pressure, and achieves a more uniform deformation effect.

Abstract

The invention belongs to the technical field of aluminum alloy plastic forming, and particularly relates to a die forging die and a forming method of a bent Y-shaped aluminum alloy forge piece, the die forging die comprises an upper die and a lower die, and a cavity matched with the bent Y-shaped aluminum alloy forge piece in appearance is formed between the upper die and the lower die; the upper die is provided with a cavity for forming an A-shaped boss and a cylindrical boss; a head process boss is arranged at the position, corresponding to the arc-shaped turning position, of the lower die, and the head process boss is in a circular arc shape. A support arm process boss is arranged at the position, corresponding to the cylindrical boss, of the lower die, and the support arm process boss is in a circular arc shape; the blanking weight is reduced, the forging pressure is reduced, and the deformation uniformity is improved.
