Electromagnetic Metalworking: Creation of a Sealed Structure via Shearing, Flanging, and Hemming
Вставка
- Опубліковано 12 сер 2024
- This video illustrates the use of the electromagnetic metalworking method to conduct several common manufacturing operations. Strong electromagnetic forces are applied to aluminum sheet metal workpieces via a single-turn copper path actuator connected to a capacitor bank discharge source. Electrical energy is charged to several thousand volts in the capacitors, and then it is released through the coil over less than a millisecond, initiating electromagnetic repulsive forces that act on the workpiece. A single coil geometry is used to conduct a set of operations, including blank shearing, 90 degree edge flanging, and air-tight sealing hemming, demonstrating the versatility of the equipment. Combination of these methods produces a sealed container structure to showcase the real-world applicability of this technology.

The Slo-Mo Guys might be interested in filming this
I was thinking about the same thing, then I found your comment.
It would really be interesting to see the metal bend and curl in 100k fps
I could watch another dozen of these
That is a neat process, especially the hemming
This is the future of home canning.. my grammy would be proud
I can't believe that I've never heard of this technology and it's been around for decades! Very cool video thanks for sharing..
It's been around since 1960s but recently got in trend again decade ago
So Cool! Thank you for posting!
Now we’re need a DIY parts list and construction 😊
One of the best videos I have seen to date. A practical application of fringe technology.
Fringe technology? This tech has been around since the Apollo days.
@@BEdmonson85 Yeah, been around but still fringe. You will not be able to point out many items in your home that have been made using the tech. So fringe older tech.
@@KallePihlajasaari Can't deny that. Good point. I think I equated the word fringe to cutting-edge or state-of-the-art.
@@BEdmonson85 state of the art just means it's too expensive for anyone to afford!
This is awesome!!!
Wow , this is a very impressive technology.
Nice video bro,do more videos like this.!
A nice way to seal the Deal..
That was cool.
thnx...bhai.....so much helpfull for me.....✌for U
Impressive
Very good. Who are the 20 sad sacs that downvote a vid like this?
"It's amazing!"
Bend radius thickness deformation calculated values will remain the same as other process ?
Does speedy process need additional factors consideration?
Not sure why I watched this (I have nothing to do with any metal working of any sort) but it's awsome. I'm wondering though dose it matter how conductive the material is? Also dose it matter how big the piece is or dose it just depend on how much it had to move?
It depends on all of those things
Ryan, Could you provide detail on the forming working template? I am curious if the forming template had, after process occurs; any "residual" magnetic field.
considering the template looks like uhmw plastic, there will be none
Dear ryan I need some help in this project can you help me making the circuit diagram of impulse generator
how is the current switched, is it a mechanical switch or solid state?
A damped sinusoidal current flows through the could when the capacitor bank discharges
Какое напряжение на конденсаторе? Отличное видео, даже если никто не ответит. Ого, сколько времени прошло %)
Wow this 1960's video looks new.
What's the purpose of the air nozzle on the last one? Venting or removal?
might be for testing how airtight it is
is that zpinch principle?
interesting , unless you doing this to metal the thickness of kitchen foil i doubt it can be done safely in a hobby enviroment because of the obviously enormous load in the capasitors (guessing old transformator style welder loading the capacirors and a relay from hell switching that current through the coil ) , wonder how big the electromagnetic pulse would be ( might overload laptops and other electronics )
How is the visible flash generated at 5:25?
I would assume the shear speed of it. perhaps igniting the air or the nylon as it went?
I think that was just a reflection of light from the camera as the angle changed on the part.
Metal deformed
aluminum is very flamable but it oxadizes instantly preventing it from bursting into flames normally but this process is so fast that the metal burns under the enourmous pressure and friction under such a short time that some flashing comes off durring the induction process
Flash --- edge formation
"low capital cost" compared to what? last time I checked a 32kJ pulse capacitor with a lifetime of 1000 shots at 80% rated voltage and 20% voltage reversal was like $10k A cap bank with long lifetime and with enough energy to do all this in a slightly larger scale probably costs like $50k and up, then you have to add the power supply, pulse forming network and safety devices, the work coils. So a magnetic pulse metal forming machine in the medium scale of things (frying pans) must cost like $100k and up. You have to use forming dies anyway so I don't see the real benefit in cost.
I think that no one invented this process. I think it was discovered by accident. Then someone was like "Wait a minute, maybe I can do something with this."
I kind of think a lot of stuff is "invented" that way.
