In this video I go over the program mode of the E21 Estun controller on the Tommy Press Brake. This allows you to bend multiple bends at once on a single part. You can adjust both the length and angle of each flange.
Great video! It’s rare to find a video without knife dies being used. You’re right there’s not a lot of sheet metal bending videos out there. When I first started to looking for instructional videos I wanted to find one on figuring out bend deductions on different materials and laying out the sheet before bending. I think that would help a lot of new fabricators
Nice work Adam. I use to make oil skimmers, most were Stainless sheetmetal but did do some Aluminum. Sadly, didn't have a press brake. My bender was a WWII 8 foot long bender. Had to make parts to make it operational. She worked well on 18g SS up to about 5 feet. But sometimes had to bend 12g SS at about 3 feet. That took an 8 foot long cheater bar on the handle. Thankfully didn't do much of that. Thanks very much for sharing. Hope you pick back up your videos soon.
That sounds like a cool old brake. I love old machinery. I’ll have to do some videos on the old Diacro I have at some point. And sorry for the delays on videos. I’m just so busy with projects it’s hard to find time in the day.
hello. The explanations are great, I wish it had been like that when they explained to me I am a press brake operator for 16 years and I tell them if when they taught me they would have explained it that way it would have been great but not only did they tell you here it is the pressure for the angle, dimension and tonnage, thanks for these videos keep going, but a slight detail do not do that of hitting die with die because even if they are hardened the dies degrade, the hardness is only 5 to 7 thousandths, and for For example, you have a die with a radius of .008 or .015, they are fine and to make them like this, hitting a die with a die with tonnage is bad because it ruins the radius instead of being .015, it becomes .024 to .032 and there are jobs that deal with fine dies and then they have to buy others just to center the die, the dies run into each other and with the minimum of tonnage, it is only one point and I say this so that the tool lasts, they are not ours, but they are our tools of work as operators #amadapressbrake #cincinnatipressbrake #accurpresspressbrake #durmanpressbrake #thrumpspressbrake
If there are high surface finish requirements when edge bending/press brake, the Swedish product Tribotextil™ can be applied in the bending/pressing tool and mechanically protect the sheet metal from scratches and other damages. Tribotextil™ is an extremely thin and very strong textile that in this process replaces lubricants in the tool.
Great videos. Im a draftsman in an aluminum fab shop and would like to be able to incorporate bending programs into our shop drawings. Could you make a video describing exactly how you make you bending templates/programs? Cheers - J
When you touch those buttons I freak out a bit. They look weak for industrial use. How much does one of the panels cost to replace? Can you access it by USB instead? If so, is the software to do so open source (in case the company goes broke and/or just stops supporting it at some point in the future)? Do you get any extra panels with the machine?
hi adam, thanks for your video. what is yp? it is not clear to me. is the distance that the punch will advance downwards from when it starts to work at "slow" speed. If I put a very high value in a small v, will the press advance until it breaks the multi v mold?
YP is the position that the internal stop in both hydraulic cylinders go down from the top position. If you put in 3.00 it goes down 3 inches etc. Essentially the cylinders bottom out internally every cycle. You can bump it down slow to check where it bottoms out so you don’t damage anything. See my next video for more on the controls.
It’s going to be different from my machine to a new one as they have made some changes since mine was made. I just write them down on a note pad with pages separated for each thickness and width of material. You need more YP for a wider piece of the same material. Once you get a piece bent say 4” wide for every metal and written down you will be pretty close when you put a like 6” or 2” wide piece in, just will be a few points lower or higher to adjust for spring back
Thanks for the video, is there a way to go single mode where the pedal controls it down slowly till you release it , when you just want to bend one part, actually just got my new unit this week, hope to get it fired up today!
Thank you! My first real video all on my own. And yes I am planning on breaking that down. By the end of the series I’ll have covered every inch of operation and setup.
