Homemade Hydraulic press brake

This press is my own interpretation of what a home shop press should
look like. I designed it to be used as a press or metal brake. It is 50" wide, so it can handle a full width sheet of steel.
I will build dies for bending pipe, tubing and angle iron as well.

Nice work. Good quality machine.

[@islandlass74]

Just watched this with Dad an Dale!!! Pretty impressive Big Bro❤

[@KimberlyRPeacock]

Awesome job. I would love to see plans. I need one of these and cannot afford a used ebay version. I also need a plate roller, for rolling vacuum cylinders and need large diameter. You give me hope that I am not on mission impossible. I just have to keep building and bootstrapping. Thank you for the inspiration.

[@BentRZR]

Thanks Kimberly! We just wing it when building, so there's not much for plans. If you're stuck on any of the design aspects, feel free to reach out.

I own a stainless steel business that I built from nothing. Trust me, if you're motivated and making progressively larger steps as you go you can build a successful shop in 5 years. The secret is to get jobs. You bid the price of the tools you need into the job. Get 50% down and never look back.

[@arcturusbbqsausagemaking2435]

Awesome build love it ,Makes my 75 ton press look like fly swatter .

[@cjbionicmarine]

This is badass man! American ingenuity at its best, lots of knowledge in your head! Not many people that build every part of a press even the hydraulics! Very impressive!

[@BentRZR]

Thanks! Yes, I'm pretty proud of it!

[@dixielivin]

And I just thought my little press I was building was cool! Great craftsmanship!!!

[@outwhitu08]

man what a beast, excellent craftsmanship, good job!

[@BentRZR]

Thanks!

[@CharlesXavierRoy]

My god ! Soo overkill, love it !

[@karolthiesen4707]

I want one of those. Maybe me and my powerarc can make a slightly smaller version.

[@geoffkelly8160]

very impressive. No pun intended.. :) I'm working on something very similar.. maybe about half the size tho.. thanks for posting.. it keeps the happy world of youtube turning. :)

[@thejourneyretold]

You must live by the saying "go big or go home" jesus hell man

[@johnshea3353]

That's insane. Awesome power. Did you fabricate the dies?

[@dennykurzawski3690]

Thank you...

[@mfarooq001]

Can you please give a detailed drawing with size for each part of this press so that it may be duplicated? Also can you please let us know about hydraulic pump specs and details.?

[@BentRZR]

Thats my hired foreman "Bitching" about my florescent lights ballast humming ;)

[@russhellmy]

Nice press. I like how you made the top and bottom beams movable rather than just one like most presses. I'm curious about the 3 pin system you are using, could you give some more details about that?

[@BentRZR]

russhellmy Thanks Russ. I went with a 3 pin pattern because it is much stronger than a 2 pin pattern. With over 400 tons of push at my disposal, the last thing I want is for the lower deck to get twisted and bind the pins inplace. The pins are 3" 4340 so with 3 in each corner, I feel pretty safe. If I loosen the lock nuts for each pin, they still pull out and slide in easily.

[@darrenmarsden5797]

Wow fantastic buddy - come to England I have a job for you

[@richardknopp8211]

man that is slick. I'm drawing up one similar for my shop great work on this build. would love to hear if you would have done anything different . and also where to buy those dies from

[@BentRZR]

+Richard Knopp Thanks Richard. Nope, everything about it is perfect. The frame and tri-pin design has handled the stresses to date with no issue. The company I bought the brake die from is: AMERICAN MACHINE TOOLS 5864 NORTHWEST HWY CHICAGO, IL 60631-0000, US Good luck!

[@LarrySbrusch]

Very nice set up. Could you please give me more information on the brand and type of Hydraulic rams you are using. How are they plummed. I would like to build something like this to bend 10 ga BBQ Pit doors.

[@BentRZR]

Larry Sbrusch Hey Larry, I built the rams myself. They are made from 12" schedule 80 Grade 359 pipe. I cut the top, bottom and plunger plates from 2" mild steel, machined them, drilled and tapped the base plate and flange. The plunger has a 4 seal system including wiper, to prevent fluid loss. They will handle your 1/4" doors with no problem, as long as they aren't wider than 51".

[@brianmcghee1080]

That press.is wicked awesome .. but what is that horrible buzzing sound?

[@repalmore]

I'm not an engineer but I think you have more ram power then frame strength. My press is about 90 ton and it's bellied out a pair of half inch bottom bars that are over 18 inches tall. One way to test is just put the ram on the bed and crank hold the valve open till you reach max pressure. If it's built properly, no problem. This is one of those times I hope I'm wrong.

[@BentRZR]

Hey Robert. I stalled the press engine out and the gauge read 3500 psi. When I first built the press. Afterwards I was able to pull all pins out! There was no deformation in the bed or frame. This was the very first test I ran. Since then I have put this unit through much more rigorous jobs and it is still straight!

[@repalmore]

Good to be wrong;0)

[@brianschaffner8372]

very sweet press id love to get the plans if you would be so kind to share or what all you used to build it and dimensions email me at [e-mail]

[@wickweckwerth1880]

Can you tell me more about the plumbing requirements of running twin cylinders. is there a flow control to equalize the pressure to each cylinder?

[@BentRZR]

+Wick Weckwerth In this setup, I don't have any special flow controls. I have isolation valving incase I want to control each ram independently, but I haven't needed to yet. When I am pressing anything, I make sure it is in the middle, so both rams apply equal pressure on the piece.

[@jacktaylor3985]

I’m been doing some research on hydraulic systems and I’ve been told I need a flow divider so the correct amount of oil goes to each cylinder, did you do this? If so any idea on what flow divider?

[@blue5632]

Can you please give the idea of the weight, and in what material you have built the frame, are m/s channels used, by the way this looks a beautiful, rugged machine, can it bend 1\4", 4 ft wide m/s sheet. Zubair Agha

[@blue5632]

Thanks for the info, must comend you for a job well done, I am wanting to build such a machine, would welcome any other info, thanks. Zubair Agha

[@RC-Heli835]

Amazing job man! What's the thickest metal it will bend?

[@BentRZR]

Thanks Blade. The thickest piece I have bent, is a 2' length of 3/4" steel plate. It didn't even struggle.

[@RC-Heli835]

@@BentRZR Wow what's it cost to build?

[@BentRZR]

@@RC-Heli835 I never kept track of the cost of materials, but the 2 cylinders needed to be precision bored by my buddy, who is a hydraulics specialist, he also machined the 3" thick base and head for the cylinders. I would say the overall cost without labor would be under 10 grand.

[@RC-Heli835]

@@BentRZR Woohoo! I figured it was pricey!😁😃

[@RC-Heli835]

@@BentRZR I am curious about the 3 pin system for the lower dies. My 1st thought is that almost all of the metal is gone in 4 panels of steel on each side. I was just curious if that is tested and proven to be the strongest design for the application? When you think of it holding 880,000 lbs it makes me wonder but I see that you have inserted and welded collars inside each hole which would make it many time harder to rip out.

[@127069]

i do like it but the 3 pins configuration has caused more weakness , side by side is bad still cool though

[@BentRZR]

Thanks Dan! As I said before, I have had 400 tons of push on the press bending some stubborn material. Afterwards, I checked the pins because I was worried about them. They slid out like they were greased! So, this configuration works very well for my needs!

[@jameshorrocks2939]

Wow.

[@jacktaylor3985]

Nice build can you bend steel plate the full length of this and how thick will it bend?

[@BentRZR]

Thanks Jack. I know it will bend 4' of 1/2" plate steel without much trouble.

[@jacktaylor3985]

BentRZR nice! Thanks for getting back to me.

[@jhitt79]

Why a gas engine? Why not use an electric motor? Don't get me wrong, I think the press is awesome just not a big fan of exhaust fumes if I can help it.

[@dennykurzawski3690]

Are the up-rights solid or channel? What size?

[@BentRZR]

DENNY KURZAWSKI The legs are 10" heavy wall channel with 1/4" Q/T 100 backing plates

[@Kimplekaks]

here is 400 ton press for you. Pacific Hydraulic Press Brake, 400 Ton

[@red66chevy]

yeah his 440 ton calc. is off by at least 300 ton. even if the cylinders are capable the frame is not. nice build other wise

[@robertatwood2503]

Kimplekaks that was a real s*** show you talk it's about something built by manufacturing company this dude built this with his own hands

[@dennykurzawski3690]

I'm sorry but what does QT 100 mean?

[@BentRZR]

DENNY KURZAWSKI (Q)uenched and (T)empered Steel is heat-treated to develop yield strength. This is a cost effective choice for applications which require high strength, improved notch toughness, superior weldability and good forming ability, as well as good resistance to brittle fracture and is suitable for structures where notch toughness at low temperatures are a design requirement. This meets specific strength and Charpy V-notch requirements.
