Inventions come from experiments. If you don’t try things that people never tried because they just don’t make sense, how will you become more than an ordinary metal fabrication shop owner?
Laser cutting machine and metal rolling machine, doesn’t go well with each other, right? There’s nothing common. But laser cutting and plasma cutting machines have similarities like metal bending press brake and metal rolling machines. That’s why hydraulic presses are being used in roll forming applications these days. But how did it happen? Somebody tried. That’s how it happened.
Even though not all of us are using hydraulic press brake in roll forming but there are quite a few who take interest on the idea. But what makes a hydraulic press brake suitable and preferable for roll forming application.
More Efficient
Whether it is stainless steel fabrication, aluminium fabrication, or steel fabrication, every metal fabricator wants to finish their products faster.
Director of marketing and sales at Beckwook Press Co. Mr. Josh Dixon said that the desire to leverage hydraulic press brake’s versatility while the speed is increasing – becoming more prevalent with most manufacturers. He also added that many clients focus on the quicker approach so that they could have a long stroke as well as allow the operator or robot to access the working areas for unloading and loading.
He continued that with Dahlstorm’s coil-applications, they just needed a small stroke which is why it was a bit different. They have been successful in accomplishing this with the custom-made hydraulic circuit, which was designed to let the short cycling of that press, at the same time preventing its ram from any overshooting that programmed retract and extend positions.
He added that it’s easy to achieve speed through separate power packs and they fire up the hydraulic fluid to produce the speed within the short strokes.
As it is a hydraulic press, the Dahlstrom Roll Form isn’t sacrificing any power even with those short strokes. Full tonnage of a hydraulic press could be delivered at any particular point within the stroke. It’s even possible for the point the press hits the part.
Extended Die Life
Most roll forming clients have their tooling for the works performed at the Dahlstrom Roll Form. Anything that should be possible to ensure that venture and increase its life likely would be incredibly appreciable.
Since the hydraulic press’ stroke can be controlled to modify speed anyplace amid the whole stroke, the controls can slow down its ram as it is going to experience the metal for punching. This is done to limit shock, which brings about more steady wears on the die.
Flexibility
Generally, a hydraulic press brake can apply the pressure all over the tonnage range. That’s why it is capable of doing different types of jobs.
Roll forming actually is a ballet of different actions — uncoiling, stopping, feeding, indexing, and punching — happening at the same time. There are likewise pneumatic gags on the instrument that powers on and off as various parts of the strip are punching at multiple stages. At the point when things cooperate as they are customized to do, it makes fabricating less stressing.
