Been a while since I posted anything to the DB, been busy, but projects are always running somewhere in the background.
This is a swage pin I made for expanding the end of a 1" od steel pipe. The shank is 1.00" Dia. and is held in an ER collet mounted in an ER/R8 collet chuck. The pipe is held in a 5C collet mounted in a horizontal/vertical collet chuck. The swage end of the pin is 0.930", sized to expand the end of the pipe to the needed external diameter for about 1" depth.
The pipe is heated to bright red in 1/2" increments; the swager being used to plunge quickly into and out of the pipe for about 1/4". The pipe is then again heated for the next plunge. If the pipe is heated for more length, it is likely to collapse ahead of the tool. This setup worked perfectly for it's purpose.
