| 中文摘要: |
| 为了提高弹体毛坯的材料利用率和降低生产成本,开展了钢管一次收口工艺改进。 根据钢管收口过程的变形规律,改进已有工装、模具,最终实现了弹体毛坯由钢管一次收口成形。 该工艺的难点是控制收口的形状,以及收口过程中模具润滑材料的选择。 工艺改进后,简化了工序,减少了工模具及刀具的消耗,改善了工作环境,降低了操作工人的劳动强度,极大地提高了材料利用率,产品质量稳定,符合制造与验收规范要求。 |
| 英文摘要: |
| In order to improve the material utilization of projectile blank and reduce the production cost, a one-pass necking process improvement was carried out by steel tube. According to the deformation rule of steel tube necking process one-pass necking process of projectile blank by steel tube was realized by improving the existing tooling, mold. The process difficulty is control of the necking shape and the mould lubrication material choice in necking process. After process improvement, the process is simplified, the consumption of the die and cutting tool is reduced, working environment is improved, the labor intensity of operators is decreased, material utilization is greatly improved, product quality is stable and the demands of manufacturing and acceptance specification can be met. |
