There are Mechanical and there are Hydraulic versions. They both are very cool but Hydraulic can be far far more accurate when working with sheet metal for example. I have used both. What they do it press down on a dis to give metal a shape that is that of the die. The brands I used are most likely still not in business but then again there were a lot of them around. Pacifc Press Break made the best Heydraulic and Cinsinati made a very good mechanical press break. One thing I did NOT like about the Cinsinati is the large heavy spinning wheel that stores energy for use when you are ready to have the RAM on the break come down and press something. Onece you press that you are committed. And these things can kill you if you are not careful. And they can kill others anywhere near if not careful. So be careful. Do NOT even use one unless you have been certified to use it.

Don't answer someone's lazy question. This guy didn't even try to make it sound like it wasn't a homework problem. He also didn't explain why he wanted this info to begin with.

What you have described I know as "press" without the "brake". They come in Fly press, "c" press, inclinable power fed etc. To me a press brake is specifically the type in the You Tube ad in post #6. The mechanical versions of which are capable of ....... to the O.P.; finish this sentence.

... Please!

You would not think how important that word is!

Also you will notice that the word is never being used in homework questions, hence yours sounds like one!

One or two cylinders push this big bar down, bending the piece of metal (or Jello or whatever) under it.

Press Brake that uses hydraulics to operate. Brief enough?

Here is one in action. This is a small one. Press Breaks are rated by size (Width of the dia ) and how much pressure they can exert to beend metal. Mostly for sheet metal. But there are also presbreaks that can press heavy up to 1/2 inch think steel.

Video of smaller pressbreak. Smaller as to width and pressure.

There nothing more satisfying than doing someone else's remedial homework.

If you don't know what it is, then you definitely shouldn't be around it, It could Mame or Kill You!

You need to pay attention while in class. Enough said.

Ashwani, May I know if you are engineer? or engineering student. If yes then you would not ask such question. You should have asked some of your more knowledgeable friends. You are wasting time of experts here in this forum.

It is what stops your car/truck/tractor when you push on it.

Re: What is Hydraulic Press Brake

08/01/2014 8:16 AM

you asked the hydraulic press brake ,this equipment do the bending of metal sheet with hydraulic force applied on the punch through 2 hydraulic cylinders .and the lower tool which is V type tool ,gives the desired angle to sheet .normally if you want to make 90degree bend then you have to choose the 85degree V and the over-bended sheet will be get the exact angle after releasing the pressure and the back to right angle function called the spring back .No-2 the upper tool will never touch the bottom of the V which will use the 4 times less force to do the job it called the air bending and an operation till reaching the bottom of V called the bottoming .

there are many kinds of press brakes like simple hydraulic with torsion bar and stopper shaft where stopper shaft limit the stroke descend movement . also there are cnc press brakes which uses the servo hydraulic with nc controls this kind of machines are able to calculate the stroke depth /tonnage and the back gauge movement by entering the sheet material /tensile strength /sheet thickness and length .you can study the delem cnc controller to understand the machine functions .

Here can be found a much larger description of the information you are looking for.

If you only want a brief description, only read the first paragraph.

Please come back for specific answers not provided by the article.

(ie. "What types do you prefer?" or "What type is the best for the type of part I want to make?" or "How do I get my arm out of this thing?")

First press, and then have a brake.

Later, I try the other eye lid.

The Lone Ranger and Tonto were riding along when they were chased by a pack of hostile Mohawks.
As they got nearer, arrows began to fly, hitting the lone ranger but they managed to out ride their pursuers.
Falling from his horse, his back looking like a pincushion, the Lone Ranger said to Tonto: "How is it that my back is covered in arrows but they didn't hit you once?"
'It's because of my aftershave' Tonto explained.
"What's that my trusted friend?" asked the Lone Ranger.
'Aramis' Tonto replied.

The Lone Ranger and Tonto are sitting round the campfire one evening. Tonto gets up, walks a few yards across the prairie, drops down to his knees, then lies flat with his ear on the ground. Gets up, walks back to the fire, puts a finger in the air and says "Buffalo come". The Lone Ranger, hugely impressed, says "How can you tell?". "Ear sticky".

I see you have made a geunuine attempt to help the OP. However, most of the respondents seem to think the question is homework, so most of the respondents have responded with a humourous reply.

Same working principle as your car foot brake system
