If it was for rolling sheet metal it would have rollers from one side to the other to keep it from warping in the center. 

If sheet metal were rolled in it the metal would roll around until it hit the handle.

The tool has to work with something round and laid across the rollers. 

The four rollers turn but on the other side the center piece is all that turns.

The tool has no crank and has to be used with the handles.

I think that rather than crimping, it was used for flaring. Years ago copper tube was flared with a hand tool to connect tubing. A flaring tool of this size could have been used to flare a tube for insertion in a water cooling condenser. It has a mounting shaft and was probably part of an assembly that installed tubes in holes and the flare held them in place, to be soldered in.

Longer shaft to accommodate wider rollers.  Slide the narrow one off, install a wider or narrower one....set screw to adjust for the size of the roller.   Maybe it was used on roof gutters? Mainly to form up an end cap?
