Hydraulic sheetmetal bender

[Ball baby]

Hey
I'm kinda upset cause I can't find a simple way to use my excavator hydraulic systems to make a sheet metal bender! I want one and I want everyone to show me how to do this!
Don't make me have to wait for details or ideas either.
I mean it

Hi Ball baby - welcome to HomemadeTools.net

Interesting build. Go ahead and try making a new discussion in our Tools in Progress subforum, and I'm sure you can get some good ideas: Tools in Progress

Hi Ball baby,

Welcome!

I'm interested in the answer to your question, too. If there's a way to do it, someone here will set you on the right path.

What are you planning to make with the new bender?

Thanks Ken
Thinking of tool boxes and tool chests etc.
First I'll take Manhattan then I'll take Berlin

Before I leave to work this morning I started with this on pillow blocks.

The bearing is concentric with housing. Inner of bearing has eccentric bore. Went in looking for ''Dodge'' ''Browning'' and ''Martin'' companies ....taper lock hubs, bearings, that kind of stuff.

That's a project I look forward to seeing, Ball baby. Welcome to the forums!

Well?
What responses or ideas have occurred for this?
That amount of power will need fine control to avoid damage to apron and bed. That will dictate gauge and potential widths for a design. Will also require substantial trunnions, but eccentric cage pillow blocks that you can align will kick this in gear. Parallel is KEY to a brake, in both planes. What material do you intend forming?

Hello Toolmaker
Can you explain some details on the pillow blocks? Would it be for the pins? I'm thinking of using the upper portion of the blade for mounting the bottom plate as it is flat and over 6 ft. Long.

To start off with from the way Your first post was worded it may not be well received by some,
However you didnot mention anything about the size or gauge of the material you desire to build this sheet-metal bender for
nor didyou state the size and breakout force of your excavator for all anyone here knows you may own a little mini excavator like a Kobelco 004 with only a few hundred pounds of force or a huge Kamatsu P600 with hundreds of tons of digging force.
Be that as it mayif you are wanting to use the bucket curl function as means to operate your bender the first thing you would need would be a means of attachment this can be done by the use of a quick tool change assembly similar the the picture below

If you already have one of these it is a simple task to design the bender around that allowing the excavator to replace your hands and arms
just add some pin locations that would resemble those of the bucket to something like this

If you are wanting to use the auxiliary hydraulics function then simply design your bender around the amount of pressure and flow that you have

Thanks everyone best response I've seen on newbie entry.
Sorry if I sounded like a ball baby at first.
My excavator is a Dawoo 140 and has a large blade thumb and 24' reach. I'd like ideas on my plan to build a bolt on bender to the blade and use the bucket for the bending force. Franks ideas are very helpful and run in parallel with my idea. I have not started the build or design just saw it in my mind while running the excavator see how the bucket force can be directed over the blade or the blade raised and lowered ad another way to operate the bending process. Like be able to bend 10 guage steel as this can curl and snap 18 " trees
Fun to be here. Just wonder why I didn't get a email notice that I had responses.
