WC67Y Digital Display Torsion Bar Press Brake: Performance and Application Advantages
Posted by PLSON Engineering Team | Last Updated: August 2026 | 6 mins read
Introduction
A torsion bar press brake is a widely used machine in the metal fabrication industry. Its main function is to bend sheet metal into the required shapes and angles by applying controlled force through the machine’s drive system.
The WC67Y digital display torsion bar press brake is designed for workshops that need stable bending performance, straightforward operation, and reliable positioning. This article introduces its main performance features and practical advantages.
1. Welded Steel Frame with Stress Relief
The WC67Y press brake uses a welded steel plate frame. After welding, the machine frame undergoes vibration stress-relief treatment to reduce internal stress.
This construction helps improve the machine’s rigidity and dimensional stability. It also reduces the risk of deformation and vibration during operation, allowing the press brake to maintain stable performance under different working conditions.
Key Benefits
- Rigid welded structure
- Reduced internal welding stress
- Improved resistance to deformation
- Stable performance during repeated bending operations
2. Hydraulic Twin-Cylinder Drive and Torsion Bar Synchronization
The WC67Y adopts a hydraulic twin-cylinder top-drive system, combined with a mechanical stop and torsion bar synchronization technology.
The two hydraulic cylinders drive the upper beam from both sides, while the torsion bar helps maintain synchronized movement between the left and right sides of the machine. This coordinated design supports smoother operation and more consistent bending results.
How the System Works
- The hydraulic cylinders move the upper beam up and down.
- The mechanical stop controls the preset stroke position.
- The torsion bar links the two sides mechanically to maintain synchronization.
- The combined system helps keep bend angles consistent during production.
This configuration is especially suitable for workshops that need reliable performance for repeated and standard bending tasks.
3. Digital Control for Back Gauge and Ram Positioning
The WC67Y is equipped with a digital control system for setting the back gauge distance and ram stroke position.
Operators can enter the required values through a simple interface. Once the parameters are set, the machine positions the back gauge and controls the ram stroke according to the programmed values.
Depending on the selected configuration, the machine can support different CNC control systems and multi-step programming functions. These functions allow the operator to:
- Create multi-step bending programs
- Run a sequence of operations automatically
- Perform continuous positioning
- Adjust the back gauge position
- Set and repeat ram stroke positions
This reduces repetitive manual adjustment and helps improve setup efficiency for multi-bend workpieces.
4. Bend Counting and Power-Off Memory
The WC67Y also includes practical functions for production management and data protection.
Bend Counting Function
The bend counting function displays the processed quantity in real time. Operators and production managers can use this information to monitor output during a shift.
Power-Off Memory Function
The power-off memory function stores important settings, including:
- Back gauge position
- Ram position
- Bending programs
- Machine parameters
If the machine loses power, these settings can be retained, helping prevent unnecessary interruptions and data loss when production resumes.

6. Who Is the WC67Y Suitable For?
The WC67Y digital display torsion bar press brake can be considered by:
- Small and medium-sized metal fabrication workshops
- General sheet metal processing companies
- Workshops producing standard bent parts
- Manufacturers looking for simple and reliable machine control
- Users who need multi-step programs without a highly complex operating system
The final configuration should be selected according to the customer’s material thickness, bending length, production volume, accuracy requirements, and preferred control system.
Conclusion
The WC67Y digital display torsion bar press brake combines a welded and stress-relieved steel frame, hydraulic twin-cylinder drive, torsion bar synchronization, digital positioning control, multi-step programming, bend counting, and power-off memory.
These features make the machine suitable for a wide range of sheet metal bending applications. Whether you operate a small workshop or a large manufacturing facility, selecting the appropriate working length, tonnage, control system, and tooling configuration can help you achieve reliable production performance and improve overall manufacturing efficiency.
