A tandem press brake is a powerful and versatile machine used in metal fabrication to bend and shape large and heavy sheet metal or plate material. It consists of two or more press brakes operating in tandem, which allows for handling longer workpieces that would be difficult or impossible to manage with a single press brake.
Key Features and Benefits
1. **Extended Length Capacity:**
- By combining two or more press brakes, a tandem setup can accommodate much longer workpieces than a single press brake, making it ideal for producing large parts such as beams, panels, and structural components.
2. **Increased Flexibility:**
- Tandem press brakes can be operated independently or in tandem, offering flexibility for different production needs. Each press brake can handle smaller parts independently, increasing overall productivity.
3. **Enhanced Precision:**
- Modern tandem press brakes are equipped with advanced CNC (Computer Numerical Control) systems that ensure precise and consistent bends across the entire length of the workpiece. Synchronization between the press brakes is crucial for maintaining accuracy.
4. **Higher Tonnage Capacity:**
- The combined tonnage of two or more press brakes allows for the bending of thicker and tougher materials that require more force than a single press brake can provide.
5. **Reduced Setup Time:**
- Using a tandem press brake can reduce setup times when transitioning between different jobs, as operators do not need to handle multiple setups for long workpieces on separate machines.
Applications
Tandem press brakes are commonly used in industries where large and heavy metal components are required, such as:
- **Automotive Manufacturing:** For producing large body panels and structural components.
- **Aerospace:** For forming large aircraft parts and assemblies.
- **Construction:** For bending large beams, columns, and panels used in buildings and infrastructure projects.
- **Shipbuilding:** For shaping large metal sheets used in hulls and other ship components.
Operation and Safety
Operating a tandem press brake requires skilled operators trained in using CNC controls and understanding the complexities of synchronized bending operations. Safety features such as light curtains, laser sensors, and emergency stop mechanisms are critical to preventing accidents and safely handling large workpieces.
Conclusion
A tandem press brake is an essential tool in modern metal fabrication. It offers significant advantages in handling large, heavy materials with precision and efficiency. Its ability to work with extended lengths and higher tonnage makes it indispensable in various high-demand industries.
1--A Hydraulic press brake is a steel sheet bending machine composed of a supporting frame, worktable, and pressing board.
2--The main frame is processed by annealing art, long time use, no shape changing, and high bending precision.
3--The Bending die is processed by special art and has a long working life. The hydraulic press brake, a CNC press brake, a CNC steel sheet bending machine, an electro-hydraulic synchronized CNC press brake, or an NC steel sheet bending machine are mainly used for steel sheet bending or stainless bending.
4--Mainly in the steel metal processing industry, Like cabinet processing, decoration, electrical lift surface wrapping, and other steel metal or stainless board processing industries.
