【摘要】：文章针对变角度缓面零件加工表面波纹不均匀、成形尺寸精度差的问题,提出了一种基于增量角度Δθ来控制增量步长Δz的方法,建立了Δz与Δθ之间的数学方程,并利用Matlab软件求解出给定Δθ时的增量步长Δz,并将该方法成功应用于变角度缓面零件成形。试验对比结果表明:该方法改善了变角度缓面零件的表面波纹,减小了底部圆形区域大小,能提高成形效率,提高变角度缓面零件的使用性能。
[Abstract]:In this paper, aiming at the problem of uneven surface ripple and poor dimensional precision of variable angle slow surface parts, a method of controlling increment step size 螖 z based on increment angle 螖 胃 is put forward, and the mathematical equation between 螖 z and 螖 胃 is established. The increment step 螖 z for a given 螖 胃 is solved by using Matlab software, and the method is successfully applied to the forming of a variable angle slow surface part. The experimental results show that the method improves the surface ripple of a variable angle slow surface part. By reducing the size of the bottom circular area, the forming efficiency can be improved and the performance of the parts with variable angle and slow surface can be improved.
