弹簧件冲压工业化生产研究

Research on Industrialized Stamping Production of Spring Components

摘要: 弹簧件是典型的薄壁火工品零件，采用传统机加单工序冲压分工序加工完成，该种生产模式生产周期长、生产成本高，逐渐与商业航天的发展方向不符。本文结合弹簧件的设计要求对弹簧件采用连续冲压工业化生产方式进行研究，结合仿真分析结果判断弹簧件加工的可行性，设计连续模具并制定冲压工业化生产工艺。研究结果表明：弹簧件可以采用连续模的方式进行生产，各项检测结果满足设计图样要求，可显著降低生产成本，同时大幅度提升生产效率。

Abstract: Spring components are typical thin-walled pyrotechnic parts, which are traditionally manufactured by separate processes of machining and single-operation stamping. This production mode is characterized by long production cycles and high manufacturing costs, and is gradually inconsistent with the development trend of commercial aerospace. In this paper, combined with the design requirements of spring components, a study on the industrialized production of spring components using progressive stamping is carried out. The feasibility of spring component processing is evaluated based on simulation analysis results, and progressive dies are designed while the stamping industrialized production process is formulated. The research results indicate that spring components can be produced by means of progressive dies, with all inspection results meeting the requirements of design drawings, which can significantly reduce production costs and greatly improve production efficiency simultaneously.
