具有双偏心套结构的摆辗机摆头可以实现多种运动轨迹,其中圆和直线运动轨迹应用较多。为了直观显示及分析运动轨迹的摆辗成形过程,根据摆头运动原理,建立摆头运动方程,应用MATLAB软件,针对摆辗机摆头圆和直线运动轨迹,叠加坯料向上送进油缸的运动,进行摆头三维运动轨迹的仿真模拟及规律分析。摆头在圆运动轨迹运动时,摆辗成形过程曲线为螺旋线,摆头摆角不为0且固定,摆辗成形过程是连续的局部成形。摆头在直线运动轨迹下,摆辗成形过程曲线为“之”字形曲线,摆角大小变化频繁,当运动曲线通过中心点时,摆头摆角为0,工件成形由局部变为整体成形,所需成形力增大。
With a double eccentric sleeve swing structure swing head can achieve a variety of trajectories, including circular and linear motion trajectory more. In order to visually display and analyze the swinging forming process of the trajectory, according to the principle of swinging head, the equation of swinging motion is established. By using MATLAB software, Simulation and regularity analysis of three-dimensional swinging motion of swing head Swing in the circular motion trajectory movement, the curve of the swing forming process for the spiral, swinging swing angle is not 0 and fixed, the swing forming process is a continuous local forming. Swinging in a straight line under the trajectory of the swinging forming curve “” shaped curve, the swing angle changes frequently in size, when the movement curve through the center point, the swivel swing angle is 0, the workpiece formed by the local into a whole Forming, the required forming force increases.
