NC Hydraulic Press Brake – Features , Cost, Controllers ＆ More

A NC hydraulic press brake is a powerful machine used in metalworking and fabrication processes. NC means numerical control. It’s designed to bend or fold sheet metal into various shapes and angles with high precision and efficiency. Here’s an introduction to its key components and workings:

1. Hydraulic System: The hydraulic system is the heart of the press brake. It generates the force needed to bend the metal. Typically, it consists of a hydraulic pump, cylinders, valves, and hoses. When activated, the hydraulic pump pressurizes hydraulic fluid, which is then directed to the cylinders to produce the bending force.
2. Numerical Control (NC): The NC part of the press brake refers to its computerized control system. This system allows operators to input bending parameters such as bend angle, bend length, and material thickness into the machine. The NC system then controls the movement of the machine’s various components, such as the back gauge and ram, to achieve precise bends according to the programmed specifications.
3. Ram and Bed: The ram is the upper part of the press brake that applies the bending force to the sheet metal. It moves up and down under the control of the hydraulic system. The bed, or lower part of the press brake, provides support for the sheet metal during bending.
4. Back Gauge: The back gauge is an adjustable stop positioned behind the bending point. It ensures accurate and consistent bending by controlling the position of the metal workpiece. In an NC press brake, the back gauge can be automatically adjusted based on the programmed bending parameters.
5. Safety Features: Hydraulic NC press brakes are equipped with various safety features to protect operators and prevent accidents. These may include light curtains, interlocks, emergency stop buttons, and safety shields.
6. Control Panel: The control panel is where operators input bending parameters and control the operation of the press brake. It typically includes a touchscreen interface or a keypad for entering data and making adjustments.
7. Tooling: Press brakes use tooling, such as punches and dies, to shape the metal. Tooling comes in various sizes and shapes to accommodate different bending requirements.
8. Applications: Hydraulic NC press brakes are used in a wide range of industries for bending sheet metal components used in products such as automotive parts, appliances, electronics, and machinery.

• Compliant with international standards, the press brake integrates top-quality electrical components and switches, ensuring reliability and ease of use across diverse industrial applications.

What Are Controllers Suitable for NC Hydraulic Press Brake?

1. Dedicated NC Controller: Many hydraulic press brakes come equipped with a dedicated numerical control (NC) system specifically designed for controlling the bending process. These controllers typically offer a user-friendly interface for inputting bending parameters, such as bend angle, bend length, and material thickness. They can control various aspects of the machine’s operation, including ram movement, back gauge positioning, and tonnage adjustment.
2. CNC (Computer Numerical Control) Controller: CNC controllers provide advanced programming capabilities and greater flexibility compared to dedicated NC systems. They allow operators to create complex bending sequences and patterns, as well as store and recall multiple bending programs. CNC controllers often feature graphical interfaces and touchscreen displays for intuitive operation.
3. PLC (Programmable Logic Controller) with HMI (Human Machine Interface): Some hydraulic press brakes utilize PLCs in conjunction with HMIs for control and monitoring purposes. PLCs offer robust programming capabilities for automation and sequencing tasks, while HMIs provide a user-friendly interface for operator interaction. This combination allows for highly customizable control solutions tailored to specific production requirements.
4. Hybrid Control Systems: Certain press brakes feature hybrid control systems that combine the advantages of both CNC and PLC technologies. These systems offer the flexibility of CNC programming with the reliability and real-time control capabilities of PLCs. They are well-suited for applications that require both complex programming and precise, responsive control.
5. Integrated CAD/CAM Systems: Some advanced hydraulic press brakes are compatible with integrated CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) systems. These systems enable operators to design bending profiles and generate bending programs directly from CAD drawings. This seamless integration streamlines the programming process and ensures accurate reproduction of complex geometries.
