Anatomy of a Roll Forming Line - Part 2 of 4: Coil Straightening & Pre-Punch
Переглядів 2,3 тис.3 роки тому
Part 2 of 4: The second step in the continuous roll forming line is leveling and straightening the metal with coil processing equipment. The straightener removes defects such as bow, camber, and twist. After coil straightening, a pneumatic punch press feeder pulls the strip into a pre-punch press. The servo controlled feeder is accurate to 0.001”. In the pre-punch press, a die punches specifica...

Переглядів 1,4 тис.3 роки тому
Part 4 of 4: The final step in the continuous roll forming line is the cutoff process and secondary operations. A linear encoder records the speed of a metal strip through the roll form mill. The speed is synced with a sensor, which detects pre-punched holes and triggers the cutoff press. Industry-leading AMS controls ensure the process is always running at maximum speed and precision. Once the...

How to Install a Metal Moulding With a Clip
Great clear explanation, definitely from long experience.
This was very well done, thank you for taking the time to put this together!
Well done, great video! Thank you for sharing mate 🙏🏻
I worked at Dahlstrom Machine works in suburban Chicago for 5 years while in high school and college. How does your company relate to that entity that was sold many years ago to Formtek?
You seem like a great boss
This is not taught in classes, and heads up companies now use tapered material. Thanks for the video.
thank you Mr. White
Thank you Mr. White for showing the important aspects of the roll forming process. Nice to see the Company Owner has no problem to makes a hands dirty. Big respect.
What is the typical line speed for roll forming
This is perfect thank you!
helpful😃
Very Informative. Thanks
which is better ? a pre cut roll forming or post cut ??
If young people who stop playing videogames and learn other trades just maybe they wouldn't have that lame excuse I don't know how. But if parents don't get involved WHY should the kids. Easier to commit crimes just sometimes the pay off is a MTHFK
very informative thank you...better than other videos too technical lol
Fantastic explanation, makes me want to do business with Dahlstrom Roll Form. Thank you.
I ran an old shear/slitter press made many years ago.2022 still cuts metal to produce boiler wrappers.
I did my Ph.D. on cold-formed hollow sections, and I enjoyed every little bit of this video. it was very well-explained. Now I'd like to do a research on Open section as well :))
Very good
خوب ه یه چیزایی بلدی
Congratulations on the new digs. Good to see growth in American manufacturing. You have to keep those old carts, they're a classic.
Congrats on the new facility! You'll have to do a walkaround tour video once you're all setup. The addition of powdercoating will prove a valuable add-on service
This is very informative. Thanks
You're welcome!
This helps a lot with understanding the roll forming process for my manufacturing processes class! Thank you for sharing!
You are very welcome!
This is the best explanation I have ever heard!
Thank You!!
Very Good explanation Rob.
Hindi me samajhna hai
It's not for everyone, but I've been really enjoying these videos! Keep it up :D
Sir cold you plz explain the function
Ksi means
Kilogram per square inch
@@carlosguerrero9022 no lol, Kips per Square Inch (kip equals a thousand pounds)
This is all well and good for evaluating our purchase decision. However, it does not help me calculate the load bearing strength of my build, because it only is a 2D specification. For example, a 1 inch square duct tape piece will hold 10x less than 10 layers before stretching and breaking. So, I must assume that a 24 ksi tensile strength aluminum will fail at 1 inch by 1 inch bar at 24,000 lbs, and a 1/8th inch thick by 1 inch long aluminum fail at 3000 lbs.
1 ksi = 1000 psi, psi-pounds per square inch
Rob, Thank You for the educational and interesting video.
My question: How do you apply the steel moulding to the wall say if it were to be a base moulding?
