枪管径向冷精锻成形技术的应用研究

Application Research of Radial Cold Forging Technology on Barrels Forming

针对小口径枪管弹-线膛一次冷精锻成形技术,通过对不同口径和不同材料的枪管径向冷精锻成形工艺的应用研究,分析精锻枪管炸裂的原因,改进了精锻工艺,并确定了检测方法和标准。经大量试验验证,采用径向冷精锻成形工艺生产的枪管性能,完全满足轻武器的使用要求,并大幅提高了产品的综合性能。

Radial cold forging is a precision forming technology for small-caliber barrel＇s cartridge chamber and rifle. The reasons of forging barrel＇s burst are analyzed and improvements of the forging process are put forward. The testing methods and standards are determined. A large number of tests validates that the gun barrel＇s performance by radial cold forging technology can fully meet the use requirements of light weapons and significantly improve the overall performance of products.
