The Research About Milling Technology Of The Lugs Of Copper Anode Plates

The milling technology of the lugs of copper anode plates is called the core technology of plastic processing of copper anode plates. Because the surface of the lugs of copper anode plates is coarse and the lugs of copper anode plates have very large pattern draft, as a result, during the electrolytic process of copper anode plates, the interface of the lugs of copper anode plates and electric sheet is reduced, the resistance of the electric from electric sheet to copper anode plates is increased, the consumptive energy of electrolysis is also increased and electrolytic efficiency is reduced. As the development of production, the intrinsic resource is hard up gradually, so the feeble-minded high efficiency mode of production is developed strongly in our country. Under this situation, the copper anode plates plastic processing unit is developed, to do plastic processing to copper anode plates, including to mill the pattern draft at the bottom of the lugs of copper anode plates at high speed, so that the interface of the lugs of copper anode plates and electric sheet is increased and the feeble-minded high efficiency mode of production is realized. But in the process that the pattern draft at the bottom of the lug of copper anode plates is being milled at high speed, the tool is worn quickly, the durability of the tool is low and the phenomenon of cracked edge of the tool is found, as a result, the blade is replaced frequently under such condition that the machine is stopped, which increases the production cost and reduces the productivity.Under such condition that the productivity is insured not to decline, in view of the high speed milling process characteristic of the lug of anode copperplate and based on the high speed cutting theory, these factors are studied and analysed deeply that are associated with milling technology in the process of high-speed milling of the lugs of copper anode plates-the tool material, the tool diameter, the amount of the cutter edge, the mode of cutting, the amount of the blade, the shape of the blade, the installation mode of blade, the cutting parameter, the geometrical parameter of the tool and the clamping mean of workpieces. Then the tool material, the tool diameter, the amount of the cutter edge, the mode of cutting, the amount of the blade, the shape of the blade, the cutting parameter,the geometrical parameter of the tool and the clamping mean of workpieces that are propitious to high-speed milling of the lugs of copper anode plates are selected and a milling cutter that is propitious to high-speed milling of the lugs of copper anode plates is got in terms of theory, to reduce the cutting force and increase the stability of system, so that the tool wear rate and the phenomenon of cracked edge of the tool is reduced, the endurance of the tool is improved and the cost of production is cut down, which offers theory reference for practical manufacture.In order to examine the rationality of the theory analysis result, a tool in accord with theoretical value has been selected from Harbin Measuring&Cutting Tool Group company with limited liability which produce more complete type of tool at home, then being installed to the machine of milling lug which is part of copper anode plates plastic processing unit, then the high-speed milling experiment of the lugs of copper anode plates is made. Through a lot of analysis and observation of high-speed milling experiment of the lugs of copper anode plates, the result is that the milling process runs smoothly and the milling quality of lugs meets the requirements of electrolysis completly, which indicates the rationality of the theoretical analysis results of this thesis.
