You need to make a fixture.
The Fixture will consist of:
1. Shaft with 2 diameters (1) peice. Turn it on the lathe from 4" dia HRS. Make a neck 2"dia x 2"lg and step to 4"dia X 1/2"lg. On the 4" dia x 1/2"lg part dril and tap 4 holes 1/2-13unc on 3...
Experiment is required. The coil is suppose to have a camber 1/8" in 10'Lg, but not allways is in this tolerances.
Stripper with nitrogen cylinders is required and closer tolerance than usual 8% of material thickness as well. And when the punch gets dull, it will try to extrude more...

I am building Roll Forming Machinery and roll forming is a process where the theory and exact engineering calculations are not aplicable. In the process of roll forming the stress deviates and creates:
SIDE EFECTS OF ROLL FORMING
Side effects can be expected with the first time running the...
Hi Christian!
If you try to solve your problem theoreticaly you can spend lots of time, apply different theoretical approach, but the results will never be correct.
The problem is that for the same type of coil, material etc, the spring effect is different and the way the line is set up - close...
