China Hydraulic Torsion-Bar NC Press Brake Suppliers - Compact Factory for Efficient Sheet Metal Bending
Product Introduction
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 its synchronization mechanism work?
A torsion bar press brake uses a rigid torsion bar connected to the left and right sliding blocks through a gear system. When one block is driven by hydraulic force, the torsion shaft elastically deforms and transmits equal torque to the opposite side, forcing both blocks to move in perfect unison. This ensures symmetrical bending angles and prevents workpiece distortion.
QWhat control system does the TPB Simple Bend Press Brake use, and how many axes does it support?
The machine is equipped with the E21 ESTUN CNC controller manufactured in Nanjing, China. It supports a 4+1 axis configuration and includes a built-in angle calculation function, eliminating the need to manually search for bending parameters and significantly reducing operator setup time.
QWhat industries is this CNC press brake best suited for?
This press brake is well suited for precision metal sheet forming across multiple industries, including electrical enclosures and server racks, automotive and aerospace structural components, construction elements such as HVAC ducts and building facades, consumer electronics housings, and general fabrication for brackets, shelves, and custom metal parts.
QCan the power supply configuration be customized for different countries?
Yes. The standard configuration is 380V / 50Hz / Three-Phase, but custom voltage and frequency specifications are available to meet regional power supply requirements. Please provide your local power specifications at the time of inquiry so we can configure the machine accordingly.
QDoes this press brake carry CE certification?
Yes, the TPB Simple Bend Press Brake is CE certified, confirming compliance with European Union machinery safety directives. This is essential for customers importing equipment into Europe and other markets that require CE compliance before the machine can be legally operated or sold.
QWhat advantage do dual servo motors provide over a single-motor design?
Dual servo motors deliver faster ram travel speeds and higher positioning accuracy compared to single-motor configurations, directly improving throughput and bending consistency. Combined with the fast-clamp tooling system that enables rapid die changes, the machine is optimized for high-volume production with minimal downtime between jobs.
