The animation shows the operating principle of a stationary-spindle swager. The dies in the SS swager have the same radial reciprocating action as in the rotary machines. However, they do not rotate around the workpiece and there is no rotation of the part being swaged. Rather, the head rotates and drives the roll rack while the spindle and forming parts stay fixed.
Three or four-die configurations are available to accommodate the different shapes. The machine can be converted to/from three to four-dies simply by changing the spindle. In addition to changing cross sectional configurations, the stationary spindle swaging machine can reduce any given shape to the same shape with a smaller cross sectional area, or can achieve a smooth transition from one shape to another, for example round to square. The swaging operation can be performed either on the ends of the work or along its entire length.
Whether you have a standard reduction from round to square or any eccentric shape requirement, Torrington’s stationary-spindle swagers stand by ready to help:
