Press brake is an essential metal manufacturing machine that can utilize punch and die to bend the metal sheet into the required shape. The press brake is widely used in many aspects, like vehicle manufacturing, rail transit, and vehicle manufacturing, and it plays a pivotal role in metal forming. With the continuous development of manufacturing, the manufacturing requirement for larger metal parts’ shapes continuously increases. In order to meet the increased market demand, machine tool manufacturers continuously expanded the size and specification of the press brake. Up to 2023, Ursviken Technology sold the biggest press brake ever produced in the industry---- a bending force of 5,500 tons and a bending length of 73 ft. Our passage will discuss the role of press brakes in metal manufacturing and the features and applications of the biggest press brakes in the world. Press brake is a mechanical equipment widely used in metal sheet fabrication. Its main function is to bend the metal sheet to the required angle and shape through exerting pressure. It forms the anticipated bending through putting the workpiece between the matched top punch and bottom die. The working principle of the press brake is to exert force on the metal sheet. The workpiece is laid on the surface of the bottom die. The top punch will descend through a mechanism or hydraulic pressure, which forces the metal sheet to bend between the two parts. Different types of press brakes vary from each other in control systems and transmission mechanisms. However, they are the same as the primary working principle, which is transforming the shape of the metal sheet via exerting force. Mechanical press brake: this is the most traditional type of press brake. It is operated by a mechanical system driven by flywheel and clutch. Although slow, it is still widely used owing to its simple structures and low cost. Hydraulic press brake: it uses a hydraulic system to move the punch, thus increasing the pressure and force during the bending process. CNC press brake: it achieves high-precision control through CNC technology, which is suitable for metal fabrication required by high precision and complex shapes. Press brake plays a pivotal role in the construction, automotive, and aerospace industries. In construction, it is used to make structural elements such as steel bars, frames, etc. In automotive processing, it is used to process bodies, frames, and other metal components. In aerospace, the press brake is used to manufacture metal parts and frames for aircraft. The history of press brakes dates back to the Industrial Revolution period. At that time, operating the press brake mainly depended on manual and simple mechanical equipment. With the development of technology, in the early 20th century, the mechanical press brake appeared. It uses mechanical wheels and a lever system to exert pressure, improving efficiency and precision. In the mid-20th century, the invention of hydraulic press brake further improved the performance of the press brake. The input of the hydraulic system not only improves the bending strength but also offers more smooth and stable pressure control, making the fabrication more precise and efficient. In the late 20th and the early 21st century, the application of CNC technology stood for a significant leap in press brake technology. CNC press brakes can control the bending process accurately, achieving precise processing with intricate shapes.

Working length: except for bearing capacity, the working length is also essential for verifying whether the press brake is of a large type. The large press brake usually has a longer worktable and bending length, usually 4 meters or more. This allows for easy access to more extensive materials. Machine size: the giant machine looks tremendous in volume and is usually 6 meters or more long. This not only contains the workbench length for matching large workpieces but also contains the height and width of the machine, making them occupy more space. Working speed: the large press brake's working speed is ten beats per minute or faster, improving the working efficiency. High-level control system: in order to deal with material of considerable size and high bearing capacity, the large press brake is usually equipped with a control system. These systems can offer more precise bending angle, pressure, and speed control. Multi-axes back gauge system: the large press brake is usually equipped with a multi-axes back gauge system, which is of vital importance to handling large material. This system can ensure the precise position during the bending process. Strengthened stability and durability: because of heavier loading, the large press brake pays more attention to stability and durability when designed. This means larger materials can be handled. Custom function: the large press brake is usually custom-made according to the specific industrial application. This includes special tools, an expanded workbench, and specific software equipment. Until 2023, Ursviken Technology has sold the industry's biggest press brake ever produced.
