The 2-WE67K-2000/8000 represents the pinnacle of large-scale bending technology—a dual-machine tandem press brake system that delivers an impressive 2X2000t combined force across an extensive 8000mm working length. Specifically designed for large-scale industrial applications where conventional single-machine press brakes cannot meet the size or force requirements, this system combines two synchronized WE67K-2000/4000 units under a centralized CNC controller to achieve seamless operation.

2-WE67K-2000/8000
TSD
The heart of this system is its advanced synchronization technology, which ensures ±0.05mm positioning accuracy across the entire 8000mm length. This precision is maintained by a real-time digital servo system that continuously monitors and adjusts the position of each machine’s slider, even when processing uneven or thick materials. The integrated hydraulic crowning system automatically compensates for frame deflection during bending, delivering uniform bend angles across extra-long workpieces—a critical feature for applications in shipbuilding, bridge construction, and heavy machinery manufacturing.
The modular design offers exceptional flexibility: each WE67K-2000/4000 unit can operate independently for smaller projects, while the tandem mode handles large-scale components. The centralized control system allows operators to program complex bending sequences once, with the software automatically distributing tasks between the two machines. Additional features include a remote diagnostic system for troubleshooting, a dual-operator station for large workpiece handling, and a high-capacity hydraulic oil cooling system to maintain stable temperatures during extended operation.

Shipbuilding: Fabricates ship hull sections with curved profiles, bulkheads requiring watertight bends, and deck plates for cargo and passenger vessels. The system handles thick steel plates up to 25mm, ensuring structural integrity for marine environments.
Heavy Machinery: Forms excavator booms with high-strength steel, crane arms requiring precise load distribution, and mining equipment parts such as shovel buckets and frame components. Its high force capacity accommodates the thick materials used in heavy-duty machinery.
Bridge Construction: Processes girder segments for both road and railway bridges, steel trusses with complex geometries, and support brackets for bridge infrastructure. The uniform bending ensures proper alignment during on-site assembly.
Energy Infrastructure: Bends LNG storage tank components with cryogenic-grade steel, offshore platform structures resistant to corrosion, and power plant boiler tubes with thick walls. The system’s precision meets the strict standards of the energy industry.
Q: How is synchronization maintained between the two machines?
A: A high-speed digital servo system paired with precision linear encoders (resolution 0.001mm) on each slider ensures real-time coordination. The centralized controller compares position data from both machines 1000 times per second, making micro-adjustments to hydraulic flow to maintain alignment. If deviations exceed 0.1mm, the system triggers an alert and slows operation for correction, preventing workpiece damage.
Q: Can the tandem system handle non-uniform materials?
A: Yes, the advanced hydraulic crowning system dynamically adjusts pressure across the bending length based on real-time feedback from material thickness sensors and strain gauges. This allows the machine to compensate for variations in material hardness or thickness, ensuring consistent bend angles even when processing plates with uneven properties—common in heavy industry applications.
Q: What is the minimum bend radius achievable?
A: For most carbon steel grades (yield strength ≤355MPa), the system can produce 1.5× material thickness radii when using proper tooling. For high-strength steel (yield strength 460-690MPa), the minimum bend radius increases to 2-3× material thickness to prevent cracking, depending on the specific alloy and heat treatment.
Q: Does the machine require a dedicated foundation?
A: Yes, a reinforced concrete foundation with a minimum thickness of 1.5m is required, designed to support a load of 30t/m². The foundation must include vibration-dampening pads (made of polyurethane with hardness 80 Shore A) between the machine base and concrete to isolate vibrations from surrounding equipment. Our engineering team provides detailed foundation drawings and soil bearing requirements prior to installation.
