Hydraulic Torsion-Bar Simple Bend NC Press Brake - Top China Suppliers and Factory for Sheet Metal Processing
Introduce
The torsion bar structure of the simple NC torsion-axis press brake is the core of the synchronization mechanism, connecting the left and right sliding blocks via a set of gears and the torsion bar. During operation, when one sliding block moves under force, the torsion shaft undergoes elastic deformation due to torque, which drives the other sliding block to move synchronously. This ensures consistent displacement of the sliding blocks on both sides, guarantees the symmetry and precision of bending angles, avoids workpiece deformation, and is suitable for medium and small tonnage bending requirements.

Frequently Asked Questions
QWhat is a torsion bar press brake and how does it work?
A torsion bar press brake uses a torsion shaft connected to left and right sliding blocks via gears. When one block moves under force, the torsion bar undergoes elastic deformation, driving the other block to move synchronously — ensuring consistent bending angles and dimensional precision across the workpiece.
QWhat control system does the TPB Simple Bend Press Brake use?
The TPB Simple Bend Press Brake is equipped with the E21 ESTUN control system, manufactured in Nanjing, China. It features an angle calculation function with 4+1 axes, eliminating the need to manually find bending parameters.
QWhat industries can this CNC press brake be used in?
This machine is versatile and used across multiple industries including metal enclosure and cabinet manufacturing, automotive and aerospace fabrication, construction and architecture, electronics and appliances, and general metal fabrication for brackets, shelves, and custom parts.
QDoes the TPB Press Brake have CE certification?
Yes, the TPB Simple Bend Press Brake holds CE certification, confirming it meets European safety, health, and environmental protection standards, making it suitable for international markets and export use.
QCan the voltage and power supply specifications be customized?
Yes. The standard configuration is 380V / 50Hz / Three-Phase, but voltage and power supply specifications can be customized to meet different regional electrical standards and customer requirements.
QWhat are the advantages of dual servo motors on this press brake?
The dual servo motor configuration provides faster operational speeds and higher working efficiency compared to traditional single-motor setups. It also improves energy efficiency, motion precision, and overall machine responsiveness, making it ideal for high-volume bending tasks.
