Why is a press brake called a press brake?

Have you ever wondered why a press brake is called a press brake and not something else like a sheet metal bender or metal former? In this article, we’ll explore the origins of the term “press brake” and how it relates to the machine’s function. Join us on a journey through history as we unravel the mystery behind the name.

The Evolution of Sheet Metal Shaping

Before the invention of machines, shaping sheet metal was a manual process. Craftsmen would attach a piece of sheet metal to a mold or scale model and use various tools like hammers, stakes, and spoons to shape it. This method is still used today in autobody repair and art fabrication shops. However, the need for more efficient methods led to the development of specialized tools.

The Birth of the Cornice Brake

In 1882, the first machine resembling a modern press brake was patented. It was called the “cornice brake” and featured a manually operated leaf that clamped the sheet metal, allowing it to be bent in a straight line. Over time, this design evolved into the leaf brakes, box and pan brakes, and folding machines we know today.

From Flywheel-Driven Machines to Modern Press Brakes

Around a hundred years ago, powered press brakes emerged, starting with flywheel-driven machines. These were followed by hydromechanical, hydraulic, and electric press brakes. But why are they all called press brakes? To understand this, we need to dive into the etymology of the term.

The Etymology of "Brake"

The word “brake” has its roots in archaic terms from Old English, Middle English, Dutch, German, and Gothic languages. In the 15th century, “brake” referred to an instrument for crushing or pounding. Over time, it became synonymous with “machine,” derived from machines used to crush grain and plant fibers. Thus, a “pressing machine” and a “press brake” essentially mean the same thing.

The Connection Between "Break" and "Brake"

The verb “break” and the term “brake” have a close relationship. “Break” originally meant to violently divide solid objects or to destroy. The past participle of “brake” was “broken.” When we examine the etymology, we find that “brake” in the context of sheet metal fabrication evolved from the Middle English verb “breken,” which meant to bend, change direction, or deflect.

The Origin of "Press"

The term “press” has its origins in Old French, where “presse” meant to crush or crowd. By the late 14th century, “press” referred to a device for pressing clothes or squeezing juice from fruits. Eventually, it came to represent a machine or mechanism that applies force by squeezing. In the context of sheet metal fabrication, the punches and dies of a press brake exert force on the metal to cause it to bend.

Putting It All Together

So, a press brake is a machine that bends sheet metal. The term “brake” comes from the Middle English word meaning to bend, while “press” refers to the machine’s ability to exert force. As technology advanced, modifiers like mechanical, hydromechanical, hydraulic, and electric were added to describe different types of press brakes. Regardless of the name, a press brake is a machine that crushes, squeezes, and bends sheet metal.
