大口径弹体的一次收口成形

摘要

The basic principle and the related factors of projectile shell body necking are introduced. The importance of temperature control in necking is analyzed. Heating temperature, heating length, heating time before necking are explained. The design of the blank before necking and necking die is illustrated.%阐述了弹体收口的基本原理及其相关因素，分析了收口成形时温度控制的重要性，并对收口前弹体加热温度、加热长度、加热时间、毛坯图的设计、收口成形工装设计加以说明。
