A press brake works by applying force to a sheet metal workpiece clamped between a punch (upper tool) and a die (lower tool), causing it to bend at a specific angle. Zhongrui’s press brakes use either hydraulic or electric drives to power the ram’s movement. In hydraulic models, oil under pressure drives cylinders to generate force, while electric press brakes use servo motors for precise motion control. The backgauge positions the sheet metal accurately, and the CNC system coordinates ram speed, force, and depth to achieve the desired bend. Modern press brakes like Zhongrui’s incorporate advanced features such as real-time angle measurement, automatic tool clamping, and adaptive control systems to optimize the bending process.
