Describe the difference between the Boltmaker and Cold Nut Former transfer as far as the motion of the transfer fingers is concerned.
The fingers on a Cold Nut Former transfer travel in a semi-circular arc away from one die to another. The fingers can be converted to rotate the blank 180o between any two dies or to transfer the blank without rotation. The fingers can be spread by the use of a special finger opening mechanism or sometimes by the punch itself.
What is meant when someone says “single extruded” bolt?
A bolt that is made from body size wire so that only the pitch diameter must be forward extruded
What is meant when someone says “double extruded” bolt?
A bolt that is made from wire which is larger in diameter than the body of the bolt thus requiring one forward extrusion to body diameter size and a second forward extrusion to pitch diameter size
