摘要：

采用GFM SX16径向锻机，研究了铍青铜QBe2薄壁管径向锻造工艺，设计并制造了径向锻造模具装置。毛坯为Φ125 mm×Φ500 mm铍青铜QBe2原始半连续铸造管坯，经两种不同的径向锻造工艺进行锻造。结果表明：热锻工步最佳锻造比为λ=2~2.3；冷锻工步应保证管坯在α固溶体中淬火软化以提高其塑性，冷锻的最佳锻造比为λ≤1.25，此时管坯表面裂纹消除。分析了铍青铜难变形合金管坯成形过程，计算了径向锻造过程的力能参数和塑性变形过程中的中心应力分布，验证了6个工步的径向锻造是获得铍青铜QBe2无缺陷薄壁管锻件的最佳方案。

By using GFM SX16 radial forging machine, the radial forging process of beryllium bronze QBe2 thin-walled tube was studied, and the radial forging die device was designed and manufactured. Two different radial forging processes were conducted for the beryllium bronze QBe2 original semi-continuous casting tube billet of Φ125 mm×Φ500 mm. The results show that the best forging ratio during hot forging is λ=2~2.3；during the cold forging，the tube
should be quenched and softened in the α solid solution to improve the plasticity，and the best forging rato is λ≤1.25, then the surface crack of tube billet is eliminated. The forming process of difficult-to-deform beryllium bronze alloy tube billet was analyzed，and the force and energy parameters of radial forging process and the distribution of central stress in the plastic deformation process were calculated，which verified that the radial forging with six steps is the best scheme to obtain the thin-walled tube forgings of beryllium bronze QBe2 without defects.
