Introduction: 5ton Press Brake Bender 3 in 1

This is a homemade 5ton hydraulic press. Made from a hydralic jack and some metal struts. check it out!

Step 1: Step One: the Main Frame

The main frame is made out of strong steel struts and leftovers.

It is very basic and the video shows how the chassis looks like. I do not have lot of footage of the build since i did not have my camera at the buildtime.

So, basicly the jack is the one that does all the work. In the top of the jack i made an M8 thread so i could bolt it to the chassis on top. that way you don't have to be affraid it would shoot loose when you are working under pressure. the chassis is a simple square that is steady, and a small strut wich can move freely within the square. since the strut would fall down due to earth gravity forces, it is held in place with 2 strong springs you can find and most hardware stores.

the video will show you most of how it works and how it looks like.

note: the springs:

the springs need to be strong enough to press the jack back into its closed position when opened the srcew too depressurize. but all force more than that will make the jack less effective while pressing due to counterforces (but 5ton is a lot of force luckily, so you have a lot of room for springs)

Step 2: Step 2: the Press Attachments

Well, the press on itself is easy to operate but it still needs some attachments to have a proper functionality.

Again, the video will show you most parts in detail. also the picture can show where the magnets are positioned and so on.

1: My benchvise bender :

seen in one of my ohter insctructables this small handy bender can also be used in this press. since the movable strut on the bottom of the jack is of metal magnets love to stick on it. so an easy way of clamping! just click and go!

2: The powerpin:

a simple 5mm thick plate with a stonechisel on it. so first the chisel is heated, shaped and welded on the metal plate. then it gets a heatthreat on the top of the chisel so it is very hard and good to press without stressing. great to use a lot of force on a small pin.

3: the boxbender:

same principle as the benchvise bender, but with loose fingers so you can easily place them to the right size to make small boxes and such. the main bar has 3 magnets to stick on the movable strut of the bender. and all small fingers have also 1 magnet in their core to stick to the main bar.

a single finger can also be used on the movable strut.

on the top of the fingers hard steel was welded from an old wrench. again later heattreated for strenght.

Thats about it. if you have questions, feel free to put them on youtube where i answer most questons on my videos :-).

Nice job. If getting the right springs was a problem I am sure bungee cords ie elastic ropes would do. I have used these for a automatic lift on a chainsaw clamp/log holder combination for cutting firewood. Work fine, cheap and if you need more power just add more....

i aso thought of strong black nbr rubber. would also work, but i thought for esthetics and the look of a solid machine, springs look better and should be able to last longer in a sunny environment :-) thx for youor comment mate!

I really like the idea with the magnets! Am gonna copy that ;o)

A note on safety, please use safety goggles when you're using any kind of power tools, and this is a power tool! If anything capsizes or shatters (like the nut), it may rocket out of the press, and you don't really want to be in the receiving end ;o)

Stay safe m8

lol, i would say, i did wear my glasses at all times, but when i rewatched my video, i was shocked haha. i'm th guy that ussually always wear the eye protection, just as respirators and such. but for the presentation i didn't wear my workclothes or any protection. not smart of me, offcourse, a press is indeed very dangerous as stuff an shatter in an instance. and the stuff that shatters is usualy more hard and sharp stuff. for the rest. magnets are indeed very handy. that's why i ordered a ton from my neighbour country to use them in a lot more projects. these are so so handy :-) thanks for watching mate! cheers!

Very Good

thanks mate ;-)

Saw the Youtube video and started figuring how to build my own. Now you've told me! Much better than your first version. And the magnets are a very useful idea. Many thanks!!

J%C3%B6rgenB%C3%B6rg made it!(author)2016-12-12

thanks mate. indedd the first one had too many downsides, so i didnt use it a lot. i've seen a lot of videos on the tube, so i tried to combine the best ideas i've seen with some of my own to make a machine that fits my needs :-). the magnet thing is really handy and didnt fail on me ones. since i've got a lot more magnets, future projects will have magnets too hahaha
