摘要:
在小直径银导爆索制造过程中，常常有4.9%的产品不能满足爆速在6 700- 7 100 m/s范围内的要求，针对此问题进行了分析和试验验证。结果表明，银管初始装药密度梯度是导致银导爆索被拉制成型后爆速波动的主要原因。通过改进工艺参数设置，减少银管初始装药密度梯度差，可以降低密度梯度产生的扰动对爆速的影响，提高银导爆索爆速精度，减少爆速波动，降低生产成本。
Abstract:
In the manufacturing process of small-diameter silver detonating fuse, 4.9% of the products cannot meet the requirements of detonation velocity in the range of 6 700-7 100 m/s. In view of this problem, the analysis and experimental verification were carried out. Results show that the initial charge density gradient is the main factor causing the detonation velocity fluctuation after the silver detonating fuse is drawn. The measures of improving the process parameters and reducing the initial charge density gradient were put forward. It can reduce the influence of disturbance caused by density gradient of silver detonating fuse on the detonation velocity, improve the detonation velocity accuracy of silver detonating fuse, and reduce detonation velocity fluctuation and production cost.
