Metal Brake backstop

[MP&C]

Here's a nifty trick I used in the shop recently, perhaps someone can make use of it on their own projects.. We had some standoff "hat sections" to fabricate a couple weeks back, and needed multiple quantities.



One of the bends was to form a 1/2" flange, so the press brake was used with a 1" wide die...



Using some rare earth magnets placed on the back side of the lower die to act as a backstop.... much easier set up than fooling with the Diacro's built in backstop..



The bonus was it pulled the galvanized sheet metal in tightly toward the magnet, a self-loading if you will...



Some of the finished products...

Robert, I'm curious how you made the reverse bends. I've tried to do something like that before and couldn't figure out a way to do it. Do you have a segmented lower die?

[MP&C]

I've got a few lower dies that are trimmed to size for such bends..

Do you know of any way to make those reverse bends without using a press-brake? I ended up clamping my parts to my workbench between pieces of angle iron and using a hammer to make the bend. It worked, but it was not the way I'd prefer to do it.

Look at this thread for the posts by TheRodDoc...

What a PITA! You can't even see threads as a guest without registering, putting in your name and location, and even introducing yourself? Seems overkill to me.

The second link worked....after I logged in. Don't these sites want people to be able to read what's posted? I understand keeping them from posting but guests should be able to see the threads at least.

I still didn't see anything on doing that reverse bend, other than the weird brake with the rollers and slots.

I did see something about making a joggle that will help me!
