旋压是利用旋压机使毛坯和模具以一定的速度共同旋转,并在旋转作用下使毛坯在与旋转接触的部位上产生局部的塑性变形。由于旋轮的进给运动和毛坏的旋转运动,使局部的塑性变形逐步的扩展到毛坯的全部表面,并完成零件的旋压加工。 旋压法可以加工圆筒形、锥形、抛物面形或其它各种曲线构成的旋转体,即用于加工各种轴对称形状的零件。 Spinning is the use of spinning machine so that the rough and mold together to a certain speed of rotation, and under the action of rotation in the rough contact with the rotating parts of the local plastic deformation. Due to the feeding motion of the rotary wheel and the bad rotary movement, the local plastic deformation is gradually extended to the entire surface of the blank, and the spinning of the part is completed. Spinning can be processed cylindrical, tapered, parabolic or other curves of the rotating body, which is used to process a variety of axisymmetric shape of the parts.
