Fractional Plate Leveler Roll Bending Device

In recent years, our country steel output continues to grow, along with the unceasing enhancement of users to the plate quality requirement, the key point of plate development is shifting from pursuit of production to pursuit of quality. Take measures to improve the plate quality has become the matter which the producer urgently need to solve. Straightening machine is the main equipment that improves the plate quality. Domestic manufacturers need to attach new technical roller straightening machine, specially has the bending roller device type straightening machine.The bending roll device of medium and heavy plate leveler is mainly to promote the straightening production efficiency, and as an important device, it can improve the straightening effect on the plate with shape deficiencies. At present, China Plate Bending straightening machine devices, mainly from the digestion of foreign technology, the essence of the technology is still a lack of research.Base on the analysis of Metallurgical equipment designs theory and the technology Shanxi Province key laboratory's roller straightener, the analysis of the bending roll device includes the following content mainly:1. Structural analysis on the bending roll device, ascertaining whose every component effect and effect thinning out mutually. Creat the mechanism sketch for the bending roll device , analysis on the motion of the bending roll devicewhich is analysed.2. Mechanics being in progress to the bending roll device analyses , builds the Mechanics model. Adopt the method finding the solution backward , asks the roller working to reach what in advance curved deflection needs a force out first , then seeks out the acting force of the bending roller hydraulic cylinder, partiality axis , axle sleeve , key , turning axis , fixing axis , the left pressure frame , the right pressure frame , balancing cylinder , screwdown cylinder again backward.3. Check for the main component of the bending roll device. By the fact that the strength check and rigidity check, verify under the condition being loaded with, if the design parameter of the bending roller device critical piece satisfy call for.In a word, by carrying out structural analysis on bending roller device, ascertaining whose motion condition; By analyzing the mechanics of the the bending roller device, ascertained accurately the bending roller force, provides a theoretical basis for the structural design and control analysis.
