Press Brake Attachment
I recently purchased a 45-ton
air-over-hydraulic press, so I'm casting about for what sort of tooling
will increase the usefulness of this new machine. One of the most obvious
is a press brake attachment.
Note: If you don't want to design and build a press brake attachment, you can buy a press brake attachment kit.
Here is a design study I did
in Rhino. My press will accomodate a 15" by 31.5" opening. This
brake is designed for 24" punches and dies.
This is a work
in progress, and will probably change significantly before it gets built.
There are some open questions. For example, I'm showing 1" shafting
for the linear bearing system. I thinking it would be better to go up
to 1 1/4" or even more. I'm showing a 5/8" deep tooling slot,
but apparently 13/16" is the industry standard for press brake tooling
I'm planning some
pretty basic specifications:
tooling held via set screws in a standard 1/2" by 13/16" deep
Back gauge features:
- Raise and lower the gage
- Slide back to the right
- Fingers on the gage bar
As usual, I have been canvasing
the various online resources to get ideas.
Below is a collection of photos
and links that are serving as inspiration.

very nice brake and press:

marring of work...

Note the massive
guide system on the sides...

Press Brake Punches & Dies: Great information on the basic punches
and dies for a press brake. Note the standard 1/2" by 5/8" tab
that is used. I will build that into my design so I can run standard tooling
that I find out on eBay and other places.
Notes and Operating Tips: A nice thread on WeldingWeb.com on press
Die and Holder Dimensions: A 4-way die would be really slick.
The nicest ready made press brake attachment I have found.
