Press brake for 20 ton hydraulic press

[DaveH]

I was looking to see what angle iron I have.
40x2
40x3
40x5
30x5
25x3
The only 6mm thick is some 25x6 - could I use this or do we think the sides are too short being 25mm long.

All the press brakes I have seen and worked with have a small bottom 'V' may be 1/2" deep, most had a maximum capacity of 2mm thick steel.
So do I need the 'V' to have long sides - does it help to bend the odd 5mm thick piece of steel?

Sorry Dave, too many choices, for me.

That's my problem as well Steve

That's the one I was looking at Willie. It's only slightly more than the cost of my press.

Is that with, or without the added cost of the new air/hydraulic unit?

it depends on how thick the material is that your bending as to how narrow the die can be. the thicker the plate the wider the die needs to be to lower the force that is needed to allow the plate to bend.

Thanks DA,
Most will be 2- 3mm thick but there may be the occasion when I want to bend some 5mm thick say by 30mm wide - small brackets.

OK Dave I'm working on the Pics, ya see my son in law has been tweaking my computer and now it won't recognize my camera.
Kids why can't they leave stuff alone.
