首发时间:2023-12-20
摘要:为了解药柱压制过程中关键工艺参数对药柱成型质量的影响,解决药柱压制过程参数选择与质量控制问题。文章选择一种氟橡胶体系压装炸药作为试验材料,研究比压、保压时间、炸药预热温度、模具预热温度对药柱密度的影响。保持单节药柱称药量、压药模具不变,选择比压、保压时间、炸药预热温度、模具预热温度分别作为变量进行药柱压制。药柱压制完成后分别测量药柱高度,计算药柱密度。试验结果表明,比压、保压时间及炸药预热温度对药柱成型密度影响显著,而模具预热温度对成型密度影响很小。

Study on key process parameters of Quality of Press-forming Grain
Abstract:In order to study the influence of key process parameters on the molding quality of the press-forming grain, and solved the selection of parameters and quality control of the grain pressing process. In this paper, a explosive of fluorine rubber was selected as the material to study the effects of different specific pressure, holding time, explosive preheating temperature and mold preheating temperature on the density of the grain. Keep the weight and pressure mold unchanged, and select the specific pressure, holding time, explosive preheating temperature and mold preheating temperature as variables for grain pressing. After the completion of grain pressing, the height of the grain was measured, and the density of the grain was calculated. The test results show that Study on key process parameters of Quality of Press-forming Grainthe specific pressure, holding time and explosive preheating temperature have significant effects on the forming density of the grain, while the mold preheating temperature has little effect on the forming density.
