China Hydraulic Torsion-Bar NC Press Brake for Sheet Metal Bending - Reliable Suppliers and Factory Solutions
Product Introduction
Overview
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
What is a torsion bar press brake and how does it work?
A torsion bar press brake uses a torsion shaft connected to the left and right sliding blocks via gears. When one block moves under force, the torsion shaft undergoes elastic deformation, driving the other block to move synchronously — ensuring consistent bending angles and precision on both sides of the workpiece.
What tonnage range is the TPB Simple Bend Press Brake suitable for?
The TPB Simple Bend Press Brake is designed for medium and small tonnage bending requirements, making it ideal for workshops and fabrication facilities that handle a high volume of straightforward bending tasks.
What control system does this press brake use?
This machine is equipped with the E21 ESTUN control system (manufactured in Nanjing, China), which supports angle calculation functions and 4+1 axis control, eliminating the need to manually locate parameters during operation.
Can the voltage and power supply be customized?
Yes. The standard configuration is 380V / 50Hz / Three-Phase, but the voltage and frequency can be customized to meet different regional power supply requirements. Please contact us with your specific needs before ordering.
Does the TPB press brake come with CE certification?
Yes, the TPB Simple Bend Press Brake holds CE certification, confirming that it meets European safety, health, and environmental protection standards — making it suitable for export to European and international markets.
