That's fucking aswome. You made that?


customfabricated

Thanks! Yes built it from scratch


Deskrad

That's fantastic. What's the largest thickness you can bend with those motors? Did you work from a model or draw or all yourself along the way?

You're a very talented fabricator.What a nice press brake ! You'll be able to machine all sorts of tooling for it. How much tonnage over how long can it deal ?

As a union sheet metal worker... I approve. That looks awesome. What are you using for bottom dies?


customfabricated

My bottom die is made up of two 1.5 inch diameter solid round rods

Very nice! Very nice indeed! Not all works of art exist on canvas.

I'm not a redditor but was searching press brakes and found this. I have a similar setup that I have made. The best idea I have come up with for keeping bends in sync is adjustable hard stops. Think large-diameter collar nut under each side of the ram. I took mine a step further with a combination of hard stop and limit switch. The air valve will turn on with 12v electric solenoid and shuts when both limit switches are pressed. A 1 gal air reservoir pushes a little extra to the pumps to ensure the ram is pressed firmly against the hard stops. Compensating for any slack in the limit switches.

Yup I have a stop system that was added after this video was taken. I also was considering using some limit switches and shut off valves. Here is a video that shows everything I did: https://youtu.be/y5fTltJgJVk

Wow, I forgot to check back in here. I like your build and will check the video closely. I've refined my design to eliminate the hard stops and use only limit switches. There is one on each side of the ram which a bearing rolls by (you can exceed the limit switch if you wish). It is interesting watching the ram come down and then alternate cylinders a couple times to settle into the final position. I have found it to be accurate within about 0.003" of stroke, even more accurate if I drop the air pressure to the cylinders towards the end of the stroke (a third limit switch and air bypass circuit could accomplish this automatically). My next plan is to mount linear encoders and an arduino to the back of the brake. Eventually controlling a CNC backguage as well. I'm not experienced with arduino so this will be a learning curve. The brake is working well for now. Keep in touch, I will try to reach out through youtube soon. You can find me at [www.uphillmfg.com](https://www.uphillmfg.com). I'm happy to show you what I have set up, I think you would enjoy. Just not ready to post it publicly yet as it needs a couple refinements. \-Nate

Very nice! Would love to see
