Ironworker Shear apparatus
Hello,
I am currently designing an Ironworker machine and I need help designing the shear. See my blog post for more info on the puropse of the machine. ( Removed Link to what appears to be a commercial site )
The shear will need to shear 1"x12" of A36 steel. I need to know what force is necessary when you are shearing with a rotating blade, or what moment would be necessary at the shearing point furthest from the pin. Even just how to calculate this would be valuble. Since the angle is changing therefore the thickness, I'm assuming you'd need some ridiculously complicated equation to find the necessary force.
I would like to use a rotating blade vs. a blade which moves vertically because the rotating blade Ironworkers usually have much simpler designs and need less force.
If it helps, I was told by an ironworker blade manufacturer that with a vertically moving blade with a 5 degree rake, you can shear it with 120 tons.
Any info helps, even just the right terminology.
Thanks,
Brianna
