【摘要】：為研究工藝參數和坯料尺寸對鉤尾框成形輥鍛件長度、最大輥鍛力矩和終鍛件填充率的影響,以13B型鉤尾框的成形為例,基于Matlab中的MBC工具箱,建立了以坯料長度為局部變量,以軋輥間隙、摩擦因數、坯料溫度和軋輥轉速為全局變量以及以輥鍛件長度、最大輥鍛力矩和終鍛件填充率為目標函數的數學模型,并進行有限元模擬,最后利用MBC工具箱中的CAGE工具箱對目標函數進行優(yōu)化,得到了優(yōu)化組合查閱表和最佳的鍛件成形參數組合,即坯料尺寸鐖160 mm×865 mm、軋輥間隙3 mm、摩擦因數0.67、坯料溫度1180℃、軋輥轉速15 r/min.通過有限元模擬和實際生產驗證,證明文中優(yōu)化方法是可行的,可藉此有效控制精密輥鍛件的長度和終鍛件的填充率.
[Abstract]:In order to study the influence of process parameters and blank size on the length of roll forging, maximum roll forging moment and filling rate of final forging, taking the forming of 13B type hook tail frame as an example, based on the MBC toolbox in Matlab, the local variable of blank length is established. Taking roll clearance, friction coefficient, blank temperature and roll rotational speed as global variables and taking roll forging length, maximum roll forging moment and final forging filling rate as objective functions, the finite element simulation was carried out. Finally, the objective function is optimized by using the case toolbox of MBC toolbox, and the optimized combination table and the best forging forming parameters are obtained, namely, the blank size is 160mm 脳 865mm, the roll gap is 3mm, the friction coefficient is 0.67, the blank temperature is 1180 鈩，
