阳极氧化挂具的设计与应用

Design and applications of special racks for anodizing

草酸阳极氧化、硬质阳极氧化处理工艺电流密度大、电压高、产热量大,必须采用压缩空气不断搅拌槽液,由此可能导致工件与挂具接触不良,引起工件烧伤和报废。设计和制作了专用挂具,保证挂具与导电杆连接牢固,挂具将工件夹紧,又便于拆卸。

High current density and voltage used in oxalic anodizing and hard anodizing process cause quantities of bath heat. Therefore air agitation is necessary which probably results in bad contact of the workpieces with the racks, and consequently produces burned and rejected workpieces. Special racks were designed and fabricated. The racks can connect with the conduct rail and the workpieces firmly, and can be disassembled easily.
