Yup. Its called spring back, I've made brake press and hydroform dies (hydroform presses use a bed of rubber to form sheet metal around a die through hydraulic pressure, the rubber conforms to the shape of the die) at an aerospace machine shop, and springback is always taken into account when engineering them.
Is the spring back effect usually resolved through trial and error and experience of the designer, or is there software that helps with compensating for this effect?
@@chenrigy experience, some trial and error, lots of calculations and a bit of luck. Don't know if there's any modern software for it, I'm sure there is but I've never seen or heard of it, we've always done it old school.
I was a press brake operator for a few years and it was pretty cool seeing a 350 ton brake lift a 12 foot wide by10 foot long piece of 1/2 inch plate into the air while bending a few inches of the edge along it's length. It's an insane amount of force.
I’m not here to complain about the editing. Thanks for providing this video showing how structured press brake dies form shapes without leading to parts becoming wedged in the dies.
@@obsoleteprofessor2034 That's hard to define. Every bend is different, depending on angle of bend, type of metal and thickness of metal. Best to do it through trial and error using a sample piece of scrap.
Back in the mid 90s we used an old 8ft Lodge & Shipley brake to form .75 thick Invar cone shaped sections that we're then welded together to make a layup mandrel. It was quite a rigged setup..custom made dies. Really strained the "vintage" brake. Had hoists on each side and one ram raised way up to get the taper, lots of bump forming but finally got it done😊.
Excellent video on press brae bending. I love how some of these have side pieces that cam inward to over -bend the workpiece to compensate for spring-back.
Having done precision and custom parts I've never had opportunities to use tooling like this. I've always had to figure my own bending process using existing tooling. I'm sure they're a must have for large volume production runs.
This was beautiful. Im a welder fabricator and I love this sorg of thing. I could do so much with this machine. Even a small machine. All I can do is dream. I sometimes dream of building a press brake so I could make tool boxes and body pannels. The precision maxhining I see in your tools impresses me so much. I was particularly impressed with the machine tools that made the circular tubing for door panels for tool boxes. Wow Just Wow
Now @0:37 i have over broke a lot of materials in sharp die sets before, but I have never seen the rear anti-movement channel before and always remember seeing the punch roll foreword right as it's at the bottom of its stroke. Smart tooling.
Nice to see again, I've also been a Press Man by profession. trained in shipbuilding school Rotterdam as a specialized PressMan (now declared superfluous, in the Netherlands the profession is dying!) Healthy and Friendly greetings from the Netherlands! Rob
Craziest job I ever had to design was a 400 ton bend on a 230 ton brake. 12 foot long piece that we had to flange on both sides and then bend up the ends. Bent the two middle sections first, separated the die sections and then bent the flanges on the ends. Separated the punch sections to leave a short section in the middle to go between the flanges and make a large frame. saved a lot of welding and fitting.
Pretty cool to see. I only have access to gooseneck, knife, flattening, and roll dies, with the exception of a few 3" wide offset dies that will do 2 bends at once. If you are hear to comment that there is nothing impressive here, that just means this video isn't for you. Most people in the world have no clue how any metal fabrication works. I'm sure it's pretty informative for them.
I finally met someone who really knows things about sheet metal bending. Thanks for your comment and hope this video can bring some new ideas for the fabricators.
You have to remember, they guys that come up with this stuff saw simular thing before they designed these. Engineering is just a sequence of small changes and over time they equal big changes.
Its a much less exciting affair when this is basically all you do for 12 hours a day 6 days a week. What is exciting, however, is when you suddenly evacuate your bowels after unintentionally converting your tooling into a claymore, shrapnel and all.
The force heats it up. You should look up videos for tube mills. They take coils of flat metal and roll it into shape. The metal comes out so hot you can burn yourself on it. Zero heat applied.
@@The4MusketeersYT EXACTLY. It the laws of energy conservation. You can neither create more destroy energy, you can only convert it. So, movement is converted to heat.
Seen it, done it. There are even punch machines that can punch and bend at the same time or after. And that was 20 years ago already. Also usually how you make 100000000 of something in a press machine that can punch / cut and bend in one of those step tools.
The new machines do the math. No more figuring out bend deductions. I prefer to watch someone operating in harmony with their brake making 79 3 piece metal door frames with 13 bends each plus a kerf for weather stripping. It looks like a ballet
Is there an equation to understand the amount of spring back of material to know how much you have to over bend it? That was difficult to word I apologize if there’s any misunderstanding.
Most of the shown tools are out of hardened tool steel, i guess there were just painted for the demonstration purpose, . A few, @ 6:21 for example uses elastomer pillows like Eladur® for springback compemsation, instead of the classic spring based lever action formtool construction.
I love how the dies move to over-bend the steel so it returns to the exact desired shape.

I've been using bending dies for years, but this video showed how much I don't know--I'll save this for future reference.
Do you have a good reference for bend allowance on simple stuff? I had one from my airplane days but I lost it.

Same bends but from different distances
would be good to have the multi stage processes in order?!

@@Artizono hey, no problem. I have a few videos on my channel that I made at work. No where near the quality of yours though.
That sure would have saved a lot of time trying to do some of those bends in the past...nice work!
4:31 Fail, the die broke the sheet. Other than that wonderful job very satisfying
Maybe the steel was from Turkey or china
Aha ikr was just bout to post the same totally ruined the asmr streak 😂
This makes me feel like a monkey compared to the guys that design those dies
You have to remember, they guys that come up with this stuff saw simular thing before they designed these. Engineering is just a sequence of small changes and over time they equal big changes.
I'm one of those guys. :)
So soothing to eyes.

I actually believe this channel deserves the amount of views
Yeah this was enjoyable to watch and good choice on music!
I love how no cats were injured during the filming of this.
Years ago I use to set up and run Breakers. I had a lot of fun. This video was was fun too!
Can we marvel for a second at just how strong the dies must be to be able to do these processes repeatedly?
Very nice and inspiring video on sheet metal bending & forming. Thank you for sharing !

Punch In punch out.
I always get thought you had to heat the metal first. It’s wild how malleable metal can be with enough force.
The force heats it up.
You should look up videos for tube mills. They take coils of flat metal and roll it into shape. The metal comes out so hot you can burn yourself on it. Zero heat applied.
@@Caderic that’s interesting. I guess it’s kinda like when you bend a paperclip back and forth and it gets warm.
@@The4MusketeersYT EXACTLY. It the laws of energy conservation. You can neither create more destroy energy, you can only convert it. So, movement is converted to heat.
Not much resists a few hundred tons of force.

My hat is off to salute the engineers
most of these are special coining dies for very specific jobs. Most shops use a variety of 90deg and 30deg air bending dies.
Its hypnotized,very cool.
kind of interesting, I wonder how long it takes to learn all the tricks and whatnot
you're gonna spend some mega bucks on that kind of tooling!
Not in the end when you can make parts others can't
Yep
Good work!!! We also have rich experience in sheet metal fab, we are a strong manufacturer in China, with high quality and competitive price.
Very nice colors.
Thanks for the Animation 🙏
None of it is animated, the dies are painted different colours.
@@nssherlock4547 Oh nice👍
Neat. I work in manufacturing, but there's not any mesmerizing metalwork.
There shouldn’t be this much vibe in a video about bending metal but its great
This has just helped me out so much lol
How do I do this without machinery? I need to bend a radius into a piece of 12 gauge mild steel.
I loved it. Thanks
Is it possible that we can learn what is this profile used for?
That's very cool. Thanks
Awesome stuff!
Steel sheets are not always the same. How do you compensate for spring back? The difference can be 5 to 8 degrees positive or negative.
These post will answer your quesitons: www.machinemfg.com/?s=crowning
Pretty cool stuff
i feel like shit when i watch this videos because i realize how little i know about mechanics even tho its my passion in life
To be fair , it probably took 1000s of hours of design and testing to get that kind of precision eventually.
Mystifyingly entertaining content
How to calculate the Spring back?
How about we take se time to appreciate that title
great video ,, dread to think of the costs involved , but then again if your turning out a lot of something , it must pay , or it wouldnt exist.
Are these punches and dies made on a wire EDM machine?
I got emotional watching the video
Me too

just search "spring back calculation" in google, you will get the answer.

These days a lot of machines do all of your bend deductions and keeps for you and also have libraries of standard bend programs
So I press whatever I want as well as print it.
I'm confused as to what this is supposed to demonstrate.
Name of the software used for making these animation???
Practical effects and lighting, it's real.
Not bad for air bending. Coining is much more effective.
Anybody else get a bit nervous about how misaligned the last setup was? Great way to launch the tooling.
