| The copper anode plate is the main raw material for cathode copper electrolytic refining,and copper anode plate casting machine is one of the key equipment of copper anode plate casting.Qualified copper anode plate not only requires chemical composition,but also need to have good physical specifications,such as clean and smooth surface,without bubble,flash,burr,slag or other bad appearance.And the main factors affecting the physical specifications of copper anode plate is the stability of the disc casting machine,then this paper take up a study on M16 copper anode plate disc casting machine which is being used.(1)Study the process system and the casting process of M16 copper anode plate disc casting machine.In accordance with the casting process,take up a systematic study on work principle and working mechanism of disc casting machine system.(2)Using Solid Works software to build virtual prototype model of disk device,drive and transmission device,clip device,anode plate Clamping device,lifting device and other device parts.Then complete the modeling and assembly work of disc casting machine,and check interference of casting machine to verify the virtual prototype model.(3)According to the physical specifications and casting process of copper anode plate,using the theory of fluid balance,calculate the maximum acceleration and the maximum angular acceleration of casting machine which meet the requirements of anode plate physical specifications.According to the production demand of smelter,calculate the best theoretical mathematical model for M16 copper disc casting machine.The best theoretical mathematical model provides a best mathematical model for production of casting,and reduces production waste,improves production efficiency.(4)Using Adams to build and simulate the dynamic model of the casting machine,and the dynamic data of the casting machine is obtained.According to the operation process of the disc casting machine,the meshing process of the outer grooved wheel mechanism is analyzed.By analyzing the working angular displacement,angular velocity and angular acceleration of the disc casting machine,the operation rules of the casting machine were found out,and then analyzed the effect of disc casting machine running state to copper anode plate.Combined with the actual production quality,and compared with the simulation data,it shows that the casting machine running in the process of shaking,and the shaking affects the copper anode plate quality,so optimization design is needed for the casting machine.(5)The parametric analysis is presented for the grooved wheel system of casting machine,then choose the driving wheel radius “r” and the center distance “a” as design variables,then theoptimization design of the original casting machine is carried out by minimizing the maximum value of the angular acceleration of the casting machine.The optimal values of the design variables “r” and “a” were found to be 283 mm and 5132 mm.And then conducts a simulation for optimized casting machine and compared the simulation results,the optimized disc casting machine angular displacement is 22.57° which is closer to the theoretical angular displacement22.50°.The maximum angular velocity of the optimized is 3.78°/s,it deduced 11.7% before the optimization,as for angular acceleration,optimized casting machine at the maximum and average values were reduced by 86.8% and 94.3%.After optimization,the disc casting machine not only more to meet the requirements of angular displacement,but also became more stable in the process,greatly improved the dynamic characteristics of machine casting,and the new copper anode plate surface are more smooth,without obvious burr,flash,reduced the failure rate. |
