【摘要】：傳統(tǒng)提高軋輥表面及輥型磨削精度的有效方法主要是專注于磨削過程中砂輪和工件的變化,主要有考慮工件軸向剛度最薄弱處,設計中心架以便提高工件的剛度;采取磨削顫振抑制、誤差補償和分析機床變速磨削的機理、變速磨削等措施。在分析變速磨削的機理、變速磨削與磨削顫振抑制、磨削精度之間的關系的基礎上,提出了根據(jù)軋輥的具體材質(zhì)、軋輥輥型結構,合理確定所用砂輪自身的磨削特性以及具體磨削加工工藝參數(shù),基于直接自適應性模糊控制的軋輥變速微進給磨削工藝策略。并在充分考慮軋輥磨床、軋輥系統(tǒng)沿軋輥軸向剛度的變化、控制磨削中軋輥變形的基礎上提出了基于自適應模糊控制的變速磨削微進給優(yōu)化自適應性控制的新策略,為提高軋輥磨削的精度提出了一種新的較有突破性、有效解決方法。目前對在線測量技術的應用已經(jīng)趨于成熟,并且在機械加工領域中得了廣泛的應用,為機械加工提供實時加工參數(shù),而且為提高加工效率、保護工件和機床、減小加工誤差提供了保障。在先進技術支持的基礎上,分析了軋輥磨削檢測在鋼性板材生產(chǎn)過程中的重要性及目前軋輥輥型及表面粗糙度檢測方法的局限性,設計了一種軋輥輥型在線測量儀,克服了軋輥磨削時合成的曲線運動,并實時測量、反饋軋輥磨削時的主要磨削參數(shù),提出了基于模糊控制理論的在線軋輥輥型測量方法,實現(xiàn)了智能測量系統(tǒng)的檢測在軋輥磨削中的應用。在線測量數(shù)據(jù)采集與磨削加工同步,其位置先于磨削系統(tǒng)。進入正常測量加工工序時,在線測量系統(tǒng)把磨削系統(tǒng)對軋輥即將加工的軋輥表面粗糙度、軋輥輥型等相關數(shù)據(jù)傳輸給模糊控制系統(tǒng),模糊控制系統(tǒng)將測量數(shù)據(jù)與理想模型進行對比、計算。最后輸出軋輥磨削的最優(yōu)磨削速度和磨削力,從而獲得理想的軋輥輥型和軋輥表面粗糙度,實現(xiàn)在線測量、自適應控制。
[Abstract]:The traditional effective method to improve the grinding accuracy of roller surface and roll profile is to focus on the change of grinding wheel and workpiece during grinding process, mainly considering the weakest position of axial stiffness of workpiece, and designing the center frame to improve the rigidity of workpiece. Grinding chatter suppression, error compensation, mechanism of machine tool variable speed grinding and variable speed grinding are adopted. On the basis of analyzing the mechanism of variable speed grinding, the relationship between variable speed grinding and grinding chatter suppression and grinding precision, the roll shape structure is put forward according to the material of roller. The grinding characteristics of the grinding wheel itself and the specific grinding process parameters are reasonably determined. Based on the direct self-adaptive fuzzy control, the rolling roll variable speed micro-feed grinding technology strategy is proposed. On the basis of fully considering the variation of roll grinding machine and roll system along the roll axial stiffness and controlling roll deformation in grinding, a new adaptive control strategy of variable speed grinding micro-feed optimization based on adaptive fuzzy control is put forward. In order to improve the precision of roller grinding, a new breakthrough and effective solution is put forward. At present, the application of on-line measurement technology has become mature, and has been widely used in the field of mechanical processing, which provides real-time processing parameters for machining, and to improve processing efficiency, protect workpieces and machine tools, Reducing the machining error provides a guarantee. Based on the support of advanced technology, the importance of roller grinding detection in steel sheet production and the limitation of current roller profile and surface roughness measurement methods are analyzed. A roll profile on-line measuring instrument is designed. The synthetic curve motion of roller grinding is overcome, and the main grinding parameters of roller grinding are measured in real time, and the on-line roller profile measurement method based on fuzzy control theory is proposed. The application of intelligent measuring system in roller grinding is realized. Online measurement data acquisition and grinding process synchronization, its position before the grinding system. When entering the normal measuring and processing process, the on-line measuring system transmits the relevant data of grinding system to the fuzzy control system, such as the surface roughness of the roller, the roll profile and so on, which are about to be processed by the grinding system. The fuzzy control system compares the measured data with the ideal model and calculates. Finally, the optimal grinding speed and the grinding force are outputted, thus the ideal roll profile and surface roughness are obtained, and the on-line measurement and adaptive control are realized.
