大型复杂“U形”件弯曲的试验研究

Experimental Research on Bending of Large and Complex “U Shape” Parts

研究板料弯曲过程中力臂和力矩的变化规律,通过数学运算与试验研究,建立了板料弯曲“U形”件的数学模型及弯曲过程的运动学图形。在制定大型复杂弯曲件工艺时,运用该研究结果可以解决弯曲回弹的问题。

For changing law of force arm and moment in research process about plate bend, with the help of mathematical operation experiment research, the mathematical model on 'U shape' parts for plate bend and the kinematics figure has been set up. When law down the technology on the complicated large bending parts, we utilize this research result to resolve the return bounce on bend.
