What Is A Press Brake Machine?
A press brake machine is a specialized manufacturing piece of equipment that can bend sheet metal. It is usually narrow and long to allow for the bending of large pieces of sheet metal. It is able to do this by lowering a punch onto a sheet metal placed on top of a die. The sheet metal can bend several times until the desired form is attained.
What Kinds Of Press Brakes Are Available?
Bending sheet metal is no small feat. It requires a significant amount of force, and the way to achieve this is with a punch that is lowered onto the sheet using several methods, including hydraulics, electrical, mechanical, or pneumatic systems. In most cases, how a press brake machine applies forces will be highlighted in its name, for example, a hydraulic press brake.
Press brake machines exert different amounts of force, known as tonnage. This terminology is used to describe the tons of force a press brake can deliver. Usually, hydraulic presses are picked for applications requiring high amounts of force. In contrast, their pneumatic and servo-electric counterparts are used in settings requiring minimal amounts of force.
Different press brakes operate at different speeds and accuracies. For instance, a servo-electric press brake is typically faster and has the highest degree of accuracy.
Things to Keep In Mind When Bending a Metal Using a Press Brake
Press brake machines can create different bends based on the metal used. As you prepare for the bending process, it is essential that you also consider the punch, die, and bending force in play.
Knowing what kind of metal is being bent is important mainly because each metal contains different properties. For instance, when dealing with a high carbon steel sheet, you will find it less bendable by a press brake machine than other metals like aluminum alloys because of the differences in strength and flexibility. In most cases, metals have a recommended bending radius that will let you know how much you can bend the material without damaging it.
The punch and die used on the press brake machine also play a significant role in the bending process. The punch refers to a solid material dropped down onto the metal, while the die is a hollow element that the metal is placed on top of before bending. It is also very hard and strong and usually resembles the desired shape of the bending metal.
In most cases, the required metal shape after a press brake operation takes place will be determined by the size and shape of the dies and punches. Since the pressing motion of the punch onto the sheet metal and die is what causes it to bend, both of their shapes have to be accurate enough for the bending job to be successful. The two elements are often designed so that you can easily interchange them to allow for a wide range of applications.
Standard Press Brake Applications
Some standard applications of the press brake machine include automotive panels, airframes, metal artistry, metal containers, and other sheet-forming tasks.
In Summary
In today’s industrialized automation world, press brake machines are necessary in almost every metal fabrication shop. However, despite being of such great importance, very little is known about them and how they function, even by those who consider themselves professionals. This is why as a fabricator, you need to understand how a press brake machine works if you want to make good use of it.
