Seamless rings are widely used in machinery manufacturing industry in many industrial fields, ring rolling is a Plastic Processing technology that produce High-performance seamless ring, it has a significant reduction in tonnage of equipment and investment, a small shock, save energy and materials, low production costs, all this is Significant technical and economic advantages. But also it has other significant advantages is effort, high productivity, product scope is broad, easy to implement, etc. Ring rolling in ring line is a large key machine, the quality of ring and the speed of Ring rolling determine the quality of product, the Production efficiency and material utilization of ring line.The D53K-2500A ring rolling machine is a device of the large ring rolling machine, The design scheme of this ring rolling machine was based on experience, not through the check test, which is resulting in some problems, such as too much mass of machine body, not sufficient resevation of strength and stiffness of key body parts. This subject of this paper is extracted and carried out the analysis due to the strength and stiffness of the cone assembly and the rack assembly of the D53K-2500A ring rolling Axial rolling body.In this paper, numerical simulation analysis is carried out to the axia rolling bodiesl of the D53K-2500A ring rolling machine shear by using the FEM code of ANSYS. Both Cone assembly carrier and the rack assembly are deeply investigated on the basic theory of finite element method. The structural improvements of Cone assembly carrier are based on the results of Cone assembly element analysis. The main conclusions of this paper are as follows.Firstly, through analysis and compare the case loading on the taper surface of the D53K-2500A ring rolling machine axial rolling body, and it is simulate under several different levels in the grid finite element, so it obtained deformation, stress, strain distribution of the cone assembly. We change the position of loading parts, we can know the maximum equivalent stress, the maximum equivalent strain. Are thess appease the material requirements and summed up the law.Secondly, we establish the frame assembly Finite element model of the D53K-2500A ring rolling machine axial rolling body, on the base of the D53K-2500A axial ring rolling machine rolling body cone assembly based on the analysis. We simulate the frame assembly under the different loading parts. Then we know the maximum deflection, the maximum equivalent stress, the maximum equivalent strain. And the result for the cone rollers provide a basis for the structure in the further improvement.Thirdly, making based on the finite element analysis, we do the structural improvements and cone anglenof the D53K-2500A ring rolling machine axial rolling body cone assembly, it base on the dates of the Finite element analysis. Ten improvement designs of tool carrier and frame are put forward and compared between each other based on the results of FEA by using ANSYS. Then we obtain the structure of relatively better, while increasing the ring roller cone axis strength and stiffness.In summary, this paper's research work, the axial ring rolling machine for rolling mechanism design, finite element analysis, structure and improvement of reference, and for improving the quality of ring rolling and guide the actual production of engineering value.
