Three-dimensional Design And Study Of Optimization On Key Structures For ABS Automatic Plastics Electroplating Line

ABS automatic plastics electroplating line is composed of frame, tank, pipe, ventilation, conducting system, cathode sweeping and other auxiliary equipments.The development and research for electroplating line is a systemic project which needs a lot of time, plenty of cost, but the research achievement has great using value.The paper emphasizes on the three-dimensional way for electroplating line and use UG software to do three-dimensional modeling for key components and virtual assembly for whole line. In the paper, the processes and methods for three-dimensional were elaborated for modeling and virtual assembly, which improve the efficiency and precision of modeling. The methods mentioned above are very useful which can be used to shorten the design cycle, increase design precision, save material and eliminate components interference during assembly process. The study also offers a theoretical basis for further research on the three-dimensional design methods for electroplating line.The paper also has done theoretical analysis for side sheet model of tank with classical Levy solution, which concludes the computed expressions of displacement of bending distortion under the pressure of static water. Theoretical basis for optimization analysis is offered for tank. It also analyzes the displacement and Von-Mises stress of tank under the load of full water with ANSYS software. The copper sulphate plastics tank which is used in company now has been analyzed. The results show that the displacement is 5.9mm and the stress is 57.6MPa which meet the using requirements of design criteria of tank.Through the analysis for tank models of different structures with stiffeners, a new optimization model of tank was pointed out. After the analysis for the optimization model, the results show that the displacement is only 1.6mm and the stress is 31.3MPa which meet the criteria completely. The new model simplifies tank production process and saves material. The quantity of using rectangle steel is down by 18% than the tank without optimization and the cost has been saved about 440 Yuan.Through the modal analysis for frame of electroplating line, it shows the former 10 modal vibration modes and natural frequency. The analysis finds out that the bending and twist distortion of frame can result in fatigue breakage of related components, even bring on the rupture on welding places. The results also show that the bending distortion of middle beams occur on 7th and 8th modal vibration modes which the displacement is the maximum. The displacement is 79.055mm and the frequency is 15.072Hz when the vibration mode is 7th. When the vibration is 8th, the displacement is 79.055mm, the frequency is 15.072Hz.Therefore, when frame and related components are working, it should avoid the frequency which is 15Hz so that it can prevent the breakage phenomenon because of sympathetic vibration. The modal parameters from analysis are conducive to improve the frame structure and optimize the parameters of beam cross-section.
