The Connecting Technology And Equipment Of Titanium Plates And Copper Ears

In order to overcome the various disadvantanges of the rivet that titanium species plates and copper ear connect in the production process of electrolytic nickel now, this paper presents the method of resistance brazing to the connection of titanium species plates and copper ears. Under the parameters of orthogonal experimental design, we successfully carry out a large area of overlap welding through a series of tests. At the same time,we study the combination of welding joint through SEM, EPMA and so on. The analysis results show that, with proper welding parameters, the connection between titanium species plate and copper ear was good performance, diffudion and fusing happened between the main metal atoms of solder and the base metal Ti and Cu reached scopic interatomic and without defects. With SEM analysis of fracture surfaces of Tensile joints,we found that a good combination of micro-joints for ductile fracture, a bad combination of micro-joints for brittle fracture. The different methods of fracture is due to the formation of different compounds in the welding process.According to the structure of resistance welding machine and the shape of the workpiece, using Solidworks software, we preliminary designed copper ear automatic welding machine and virtual assembly. Reference to the virtual assembly drawings, using CAD mapping technology, we initially designed the mechanical assembly General Plan of copper ear automatic welding machine. Then,we preliminary designed the main parts of welding equipment,such as electrode contacts with the first,copper ear supporting frames,plate positioning block,slide,welding table and so on.And we preliminary determined the model of the electric motor. Next, according to the designing sizes,we will produce the components, then assembling with the whole body.So we can design the copper ears automatic welding equipments to the needs of the production.
