50 TON PRESS BRAKE MODIFICATION
50 TON PRESS BRAKE MODIFICATION
(OP)
I am going to modify my Harbor Freight 50 ton press brake and need some advice. The upper C channel is 7” tall, 2 5/8” deep and 1/4” thick. The lower C channel is 7” tall, 2 5/8” deep and 3/8” thick. Both C channels are 35” to the support pins/ mounting bolts. I would like to widen the working opening from 32” to 52”. How do you calculate the new C channel size for the added span? Looking at the picture of the press, I would like to attach the existing upper C channel that houses the hydraulic ram to the new C channel as to not have to cut out all of the factory welds. If you have any questions regarding measurements and specs, please ask me.

How are you planning to attach the new C-Channel to the existing one?

A press brake is a different tool, intended for a different job.

I could "brake" a 48" wide sheet of .090" aluminum with my bare hands...to a very large radius. Sharper radius = more force, maybe a very large force, depending on what you want to do.
I'm guessing you're planning to use some sort of simple stand-alone brake tooling with the press. Getting a sharp, 48" long, uniform bend with pressure applied to the tooling at a single, central point will require a VERY stiff tool. Look at the construction of factory-built bending equipment for a reality check on this point.

Go to a used machinery dealer and ask them to find you a used 48" press brake.
That's actually pretty small for a press brake; they may have larger ones ready to go.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Alignment of the die set is important. I don't think this DIY hydraulic press brake produced very good results.
