波导法兰盘的冲制是指外形和内孔而言。我厂波导法兰盘品种多,批量小,技术要求高,尤其是内孔尺寸要求严,光洁度要求高。长期以来我厂均用机床切削加工,批量稍大,就变成了全厂的“细脖子”远远满足不了生产的需要。为了适应批量生产,我们设计制造了波导法兰盘的简易精冲模,改善了劳动条件,提高了生产效率,取得了良好的技术经济效果。所谓简易精冲是应用精冲原理,采用光洁冲裁的凸、凹模形式并改进模具结构,用带气垫的通用压机,来获得精冲零件的一种冲压方法。与一般精冲比较,具有简化冲模结构,缩短设计与制造周期,降低生产成本等优点。另外,由于使用通用压机,此种方法便于采用。下面仅就我厂的H62黄铜,厚度为4～9毫米的波导法兰盘的简易精冲方法加以说明。
Waveguide flange punching refers to the shape and bore in terms of. Our factory flange waveguide variety, small quantities, high technical requirements, especially the requirements of the inner hole size, high finish requirements. For a long time I have used machine tool cutting plant, slightly larger, it becomes the whole plant “thin neck” can not meet the production needs. In order to meet the mass production, we design and manufacture of waveguide flange precision fine die, improved working conditions and improve production efficiency, and achieved good technical and economic results. The so-called simple fine blanking is the application of fine blanking principle, the use of smooth blanking convex and concave die form and improve the die structure, with a universal cushion with a cushion to get fine blanking parts stamping method. Compared with the general refined red, with a simplified die structure, shorten the design and manufacturing cycle, reduce production costs and so on. In addition, this method is easy to use due to the use of a universal press. The following only I H62 brass plant, the thickness of 4 ~ 9 mm waveguide flange simple fine blanking method to illustrate.
