小长径比药盘钢模压制成型工艺研究

Research about Press Shaping Process of a Charge Disc with Small Ratio of Length to Radius

通过对炸药压装成型过程的深入分析，揭示了钢模压制小长径比药盘的技术关键是必须使所装填的散粒体炸药在压件的横断面上全面实现其质量的合理分配，设计定程式双向钢质压模，合理确定垫圈厚度和括药器结构。

This paper reveals that the key technical condition of pressing the charge disc with small ratio of length to radius by a steel die is to realize the reasonable dispersion of moulding powder charged on the cross section of the disc. The problem can be solved to design a bidirectional steel die with fixed travel ,and to get a resonable washer thickness and a good scraper structure.
