Nowadays, when people talking about press brake, they mainly refer to the bending machine for sheet metal bending. However, do you know why such a sheet metal bending machine is been called press brake? For most people, this question confused them for a long time. Before you understand why it is called the press brake, you must understand the meaning of the terms.
The press brake is a pressing machine that is perfect for bending sheets and plate materials. It is most commonly used for sheet metal. The structure of the press brake mainly includes a bracket, a worktable and a clamping plate. The workbench is composed of a base and a pressing plate, and is placed on a support. The base is composed of a seat shell, a coil and a cover plate, and is connected with the clamping plate through a hinge. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, so as to realize the clamping of the thin plate between the pressing plate and the base.
The Origin of The Name of Press Brake
From the origin of the name, please note that the term press brake is completely wrong, because nothing has been damaged or broken. A press brake doesn’t “step on the brakes” to bend, so why is it called a press brake? A brief history of a few words reveals the answer.
The term brake, as used in modern sheet metal fabrication, was derived from the Middle English verb breken, which means to break or change the direction of or deflect. A few centuries later, the past participle of “brake” evolved into “broken”. This means that when you look at the etymology, “break” and “brake” are closely related.You could also “break” when you drew back the string of a bow to shoot an arrow. You could even break a beam of light by deflecting it with a mirror.
Now we know the verb “brake” refers to a machine that bends. And where does the word “press”—describing the machines we know today—come from?
The word press was derived from the phrase presse in the 1300s. This noun means to crowd or crush. In the 14th century, the press became a machine used to juice olives and grapes and for pressing clothes. Since then, press has evolved into a machine or machine that applies force by pressing. In manufacturers’ applications, punch presses and molds can be called “presses” that apply pressure to metal plates and bend them.
That’s where the “press brake” term comes from. Now that you understand where the name comes from, you know why the tool is called a press brake. You also understand better how it works and how the device shapes the sheet metal.
The Development of Metal Sheet Bending Machine
In the past, if you wanted to bend sheet metal, you were forced to attach it to an appropriately sized piece of sheet metal mold, which was filled with lead shots or sand. The T-stake was then used to pound the sheet into the desired shape. This was most common when making breastplates for armor suits. While it is still a method used today, it is manual and taxing on energy and time.
The first press brake was developed in the early 1920s. Today, both electric and mechanical press brakes help make it easier to shape sheet metal. When it was invented, it was a tool for pounding and crushing. Eventually, the name brake because synonymous with the machine, and thus, the device was called a pressing machine.
With the advancement of bending technology, bending machines have evolved from manual bending machines to mechanical bending machines, pneumatic bending machines, hydraulic bending machines and fully automatic bending machines. Senfeng Leiming automatic bending machine is widely used, reducing unnecessary operation procedures and saving manpower and material resources.
