The Parametric Analysis And Scheme Determination Of 2650 Medium And Heavy Plate Leveler

In recent years, with the rapid development of the industry in our country, plate has been widely used, more and more varieties and specifications of the plate products are appeared, to meet the demand for products, designing the plate straightening equipment which straightening range wider has great theoretical significance and engineering practical value. the paper is according to changes in product mix of the Bao steel factory, they need to add an medium and heavy plate leveler which could straightening the plate in thick 50mm and wide 2650mm, researching the straightening program and reasonable choice of the main parameters for the product characteristics of the plate leveler have the wide range of specifications and yield strength, the thesis's research contents as follows:First, based on the roller straightening theory, determined the determination principle of the roller leveler main parameter. On this basis, combined with VC++ programming software had compiled the design and calculation system of the medium and heavy plate leveler. According to the basic parameter and the technical requirements of the plate which the medium and heavy plate leveler straightening, computing the multiple sets of parameters program and comparing and analyzing the results repeatedly by the calculation system. Determined the main design parameters of the medium and heavy plate leveler reasonably.Second, analyzed the straightening ability of the medium and heavy plate leveler, According to the MATLAB software, analyzed the relationship between the parameters and the total and maximum straightening force of the leveler in the specifications and materials intensity range of straightening plates. By plotting the graph, based on based on the requirements of the total straightening force and maximum force, to obtain the specification range of the work piece which the leveler straightening.Finally, described the general scheme of the medium and heavy plate leveler, and combined with the straining force which obtained from the design and calculation system of the plate roller leveler, the pre-stressed rack is carried out the static strength analysis that is the basis component of the leveler. obtained the stress and displacement distribution regulation which apply the straightening force.
