南昌航空大学科技学院学士学位论文滚筒式抛丸清理机的总体和结构设计学生姓名: 杨挺 班级: 0781053指导老师: 张晓荣 摘要: 本滚筒式抛丸清理机的工作原理是利用高速回转的叶轮将弹丸抛向滚筒内不断翻转的锥铸件或者锻件,来清除其表面的残余型砂或者氧化铁皮、清理均匀、生产效率高,适宜于中、小型铸锻车间清理小件使用,解决了小批量零件的清理工作。设计过程中,利用一级链传动减速带动滚筒和提升斗的回转和实验弹丸的循环使用。为了清除铸件或锻件表面的残余型砂或氧化铁皮利用高速回转的叶轮将弹丸抛向滚筒内不断翻转的零件。要求达到如下目的:a综合运用机械和电器知识;b弹丸循环及分离装置设计;c除尘器设计;d弹丸循环及分离装置、集尘器零件的设计。采用一级齿轮传动带动的抛丸器滚筒的抛丸工作,同时,运用干式旋风型除尘装置进行尘土分离工作。弹丸循环装置由滚筒护板于壳体之间的螺旋带提升斗及分离筛组成。由叶轮抛出的弹丸射击工件之后,从滚筒护板上的格子孔进入护板与筒壳体之间得空隙内,借助螺旋作用流到旋转的提升斗内。提升到上部,经过分离筛去毛刺、钉子、芯骨、砂、粒等。完整的弹丸经导入管再送入抛丸器内。设计针对小批量零件的清理工作,是有较好的实用价值和经济效益。设计对象为总装、弹丸循环及分离装置、除尘器设计、提升斗。本机利用带有独特的集尘装置安装地点不受车间同风管路的限制卫生条件好,本机设有自动停车装置,操作简便。关键词:型砂 氧化铁皮 毛刺 螺旋 指导老师签名:Shot Blasting Machine Drum and structural design of the overall Student name: Yang Ting Class: 0781053 Supervisor: Zhang XiaoRongAbstract: The drum-type shot blasting machine works by using high-speed rotation of the impeller within the projectile thrown constantly turning roller cone castings or forgings, to remove residual sand or the surface oxide skin, clean uniform, high efficiency, suitable for in small and medium casting and forging shop clean up small pieces to use to solve a small part of the clearance volume. The design process, using a slow drive roller chain drive and enhance the struggle of the rotation cycle of the experimental use of the projectile. In order to remove residual casting or forging the surface of sand or iron oxide with a high-speed rotation of the impeller Pillay will continue to turn within the projectile thrown to the drum parts. Required to achieve the following purposes: a comprehensive use of mechanical and electrical knowledge; b projectile design cycle and the separation device; c filter design; d shot cycle and separation equipment, dust collector parts of the design. Using a gear-driven shot blast wheel drum work, while the use of dry-type dedusting cyclone dust separation device work. Projectile loop device of roller retaining plate in between the spiral shell with a separate screen to upgrade the Big Dipper and composition. Firing projectiles thrown by the impeller workpiece, the roller retaining plate from the grid plate and the cylinder bore into the shell protecting the gap between the have, the use of screw rotation to enhance the role of flow within the bucket. Elevated to the top, through the separation screen deburring, nails, core bone, sand, grain and so on. Complete projectile shot by the import into the canal inside. Designed for small batch parts cleaning work, there is a good practical value and economic benefits. Design object for the assembly, projectile circulation and separation devices, filter design, promotion fight. This machine is used with a unique location from workshop dust collection equipment installed wind pipe with good sanitary conditions restrictions, this machine is equipped with automatic stop device, easy to operate.Keyword: moulding sand millscale burr helix Signature of Supervisor:
