Curving Molding Formation Modelling And Mechanics Analysis

In produces and in the life widespread application along with the curving molding, also day by day enhances to the curving molding's performance and the quality request, however by the rolling way production curving molding's process is a complex elastoplasticity distortion process, contains the material, the geometry and the boundary contact and so on multiple non-linear problems, expresses very difficultly with the accurate mathematics relationship. Therefore, to the plate forming process's distortion rule, distortion mechanics as well as and so on carries on the thorough analysis with it related roller's design and the while going along establishment appears more and more important.The paper research content originates from the National Technical department project "the dummy specimen integration simulation platform and in the non-sign burglar-proof door key equipment development applied research". In view of the Zhumadian culmination family profession production curving molding's rolling mill the crack which and the break phenomenon appears in the rolling process, proposed the corresponding research subject.The article first introduced regarding the curving molding research's domestic and foreign present situations, and the commonly used two kind of processing method ramming and the rolling production working procedure and the characteristic, through the product quality and the production benefit's contrast, has obtained the continuous rolling in the curving molding production superiority.This article to this rolling mill various spare parts correct measurement foundation, has completed the obtained metrical data with the SolidWorks software rolling mill's three dimensional modelling, has carried on the analysis with the aid of finite element analysis software ANSYS10.0 to the modelling, has completed the following work: 1st, through to rolling mill's various components survey, to rolling mill modelling. 2nd, the use finite element's method, completes the roller finite element model in the ANSYS software the establishment, the load, the solution and the computed result analysis, the analysis curving molding distortion process and the stress situation. 3rd, through draws the research conclusion to the molding distortion process's analysis and the roller while going along theoretical calculation.Through finite element simulation, reappearance rolling process, Uses the numerical simulation the method to carry on the stress analysis to the flow of metal, on the one hand can forecast the different craft the final outcome, but can also simulate the technological process, and may act according to the various requirement makes the revision to the craft plan and the parameter, obtains the most superior craft. On the other hand may simulate the steel in rolling process Microstructure change, after and forecasts rolls over, the steel performance, thus the optimization technological parameter, replaces the massive metallographic test and the technological parameter research, not can only reduce the economic loss which, because tests blindly brings, saves the enterprise scientific research cost, but is also advantageous in explores the new craft the goal, solves the actual production problem for the enterprise to provide the reference.
