APPARATUS FOR BENDING RODS

A rod for forming a glow plug is fed between two grooved rollers one of which is rotatable around the other to make a 90 DEG bend in the rod. The rod is then fed to an arcuate die groove of small radius, the groove being carried by a two part die. The bent portion of the rod is clamped in front of t...

Zusammenfassung:	A rod for forming a glow plug is fed between two grooved rollers one of which is rotatable around the other to make a 90 DEG bend in the rod. The rod is then fed to an arcuate die groove of small radius, the groove being carried by a two part die. The bent portion of the rod is clamped in front of the arcuate die groove and a grooved roller is swung orbitally 270 DEG around the arcuate die groove to force the unbent portions of the rod into and around the arcuate die groove, thereby forming a 270 DEG arcuate bend of small radius. The two parts of the die are then separated and the bent rod is removed therefrom.
