复合材料发射箱箱体加工技术研究

Solve Processing Technology of Composite Launcher Container

针对某型号武器复合材料发射箱箱体机加工过程中由于工件刚度差、易变形,导致的加工尺寸超差及质量缺陷(如毛刺、分层、崩边)等问题,开展发射箱机械加工技术研究和工艺优化。实验结果表明:通过合理设计发射箱装夹定位方式,优化加工刀具及工艺参数,能够实现对加工缺陷的有效控制,保证产品加工质量;通过对箱体不同工序、工步进行优化,统筹安排管理,将发射箱单件加工时间从100 h降到46 h,生产效率提高54%,大幅降低了生产成本。

In order to solve the probrems such as the machining defects such as delamination,burrs,and chipping due to the poor stiffness and easily deformation of the launcher container,the technology on mechanical processing and optimize the process on a weapon composite launcher container are studied.Result of the test shows that the machining defects can be effectively controlled to ensure the quality of launcher container by designing a reasonable clamping method,optimizing the cutting tools and machining parameters.By optimizing the different processing steps and overall planning,the working time is shortened from 100 h to 46 h,the production efficiency is increased to 54%,significantly reduced the production costs.
