Stationary Spindle Swager

Stationary spindle (SS) swagers offer infinite possibilities in cold or hot forming of cross sectional shapes on tubing and solid bars. Parts swaged on the SS swagers include fluted screwdriver points, rectangular soldering iron tips, gun drills, flexible shaft ends, punches, and shaped tubing for special applications. The machine may also be used for compacting material in tubing of other cross sections than round.

Operating Principle

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.

Machine Specifications

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.
