SHEET METAL SHRINKING AND STRETCHING MACHINE
The cast “G” frame foot-operated shrinker and stretcher has a 6” throat depth and is mounted on a welded steel floor pedestal. The pendulum motion of the foot pedal and the cam mechanism inside the “G” frame, which is balanced by adjustable weights on the treadle rod, controls the stroke of the ram.
Operation of the Model 1447-6DT foot operated shrinker and stretcher is very simple. The operator needs only a few minutes to acquire the knack of feeding the material through the jaws to obtain the desired shapes. The shaping is accomplished swiftly with a minimum number of strokes of the ram. No jaw adjustment is necessary for different thicknesses of metal.
SHRINKING AND STRETCHING JAW ASSEMBLIES
The Model 1447-6DT can be equipped with shrinking jaw and/or stretching jaw assemblies. They are easily interchangeable by means of quick change dovetail slidetype anvils. The stippled surfaces of the jaws are parallel, and grip the work at two points. The action of the jaws then shrinks (or stretches) the material between these two points. For removing wrinkles from the flanges of a channel section, extended jaws are available. Jaw assemblies for special shrinking/stretching applications are available or can be designed and manufactured upon request.
The stippled working surfaces of the jaws grip the work piece and impart a finish to the material surface. A standard No.2 stippled jaw surface is used for a wide variety of applications. There are three finer grades of jaw stipple available: Nos. 1, 0, and 00. For work with harder alloy metals, a more coarse No.3 stippled jaw surface may be appropriate. When stippling on the jaws is worn smooth, they can be reground and restippled in any grade for a nominal charge.
