Deformation Analysis And Structure Improvement For Core Components Of Coiler

Now, with the pace of China’s manufacturing industry growing stronger, a variety of modern design methods more and more widely are applied to optimize the design of the manufacturing equipment. In order to better promote the country’s industrialization process, the active promotion and application of new technologies are applied to optimize production. Through a variety of ways to access a large number of related documents, analysis the important role of the cold-rolled strip winder and reel in the rolling production, research and analysis the key parts and components sector plate of the poor rolls and jaw stress state in the actual strip production process because of the structure is irrational, resulting in the bending stress is too large, resulting in part of local is damaged and the coiler’s severe vibration. Bending deformation of sector plate is too large lead to the coiler’s jamming in the process of shrink. The bending deformation of the jaw is too large to result in the strip bite is not tight.Solving these problems, we have the theoretical analysis of the stress state and calculation of the relevant design parameters, focus on application of the classical finite element software ANSYS are played to the static, modal, transient dynamic analysis of fan-shaped plate and jaw, and optimized comparative validation analysis with the results of the analysis combining of failure modes in the actual production Finally optimize the structure. The main contents are as follows:First, according to the parameters of the actual production in the20-roll mill coiler, calculate the radial pressure of the roll, and make the roll simplified into a shaft and obtain its theoretical stress analysis. Analyze the bending moment and torque of the different locations, and finally synthesize the bending and torsion to determine the adequacy of its strength.Secondly, according to the coiler’s CAD drawings, use UG software to create accurate three-dimensional model of the fan-shaped plate and the fixed jaw. Because this model is imported to the ANSYS software, so simplification to establish a simplified model of the fan-shaped plate and the fixed jaw is necessary. Sector plate structure is relatively large and more complex, according to the characteristics of the basic symmetry, establishes the three-dimensional model of the second one, so that can be analyzed well in the ANSYS software.Then import the good three-dimensional model to ANSYS software, select the appropriate element type and meshing accuracy, combining with the part’s actual working conditions, load properly and solve its static, modal and transient dynamic Analysis. Solving Fan-shaped structure of the board, we just analyze the half model. Set the symmetry constraints and the final extension. Force status of the fixed jaw, we just analyze the period, so that accuracy can be higher. At the same time, the length of the fixed jaw size is relatively large, and therefore can be simplified into a plane strain finite element analysis.Finally, according to the finite element analysis results, combing with the destruction of the actual production, optimize the large local deformation, and make the finite element analysis for the optimized model. Determine whether the optimal results are gained by the contrast of the stress and deformation. Make the topology optimization design of large fixed jaw plane’s analysis.
