2. Motor-driven Ram: The ram is the moving part of the press brake that applies force to the metal sheet to bend it. It is driven by a motor that generates the necessary power to move the ram up and down. The motor-driven ram allows for precise control over the bending process, ensuring accurate and consistent results.
3. Die Set: The die set is a critical component of the press brake that shapes the metal sheet into the desired form. It consists of an upper die and a lower die, which are securely mounted onto the machine. The upper die is attached to the ram and moves with it, while the lower die remains stationary. The shape and configuration of the die set determine the final bend angle and radius.
4. Backgauge: The backgauge is a positioning device located behind the die set. It helps to accurately position the metal sheet during the bending process. The backgauge can be manually adjusted or controlled through a computerized system, allowing for precise and repeatable positioning.
5. Control System: The control system of a mechanical press brake is responsible for regulating and monitoring various parameters, such as bending force, ram speed, and backgauge position. It ensures precise control over the bending operation, resulting in consistent and high-quality bends.

Understanding the components and functions of a mechanical press brake is essential for maximizing its potential and ensuring safe and efficient operation. Each component plays a vital role in the bending process, contributing to the machine’s accuracy, repeatability, and overall performance.
