分析了弹体收带工艺产生的变形问题,理论计算弹带收带所需挤压力,确定收带弹体变形产生的原因,通过改进收带工艺和夹爪结构、优化调整收带芯子与弹体内膛配合间隙,减少了薄壁弹体收带变形,降低了收带废品率,保证了薄壁弹体收带质量,节约了生产成本。 The deformation problem of the take-up process of the projectile is analyzed. The compressive force required to close the take-up band is calculated theoretically to determine the cause of the deformation of the take-up projectile. By optimizing the take-up process and the structure of the clamping jaws, With the body with the gap with the breech, reducing the deformation of the thin-walled body with take-off, reducing the rate of take-off of waste, to ensure the quality of thin-walled body with take-off, saving production costs.
