Description
The torsion bar press brake, often called a mechanical synchronisation press brake, uses a purely mechanical torsion bar to synchronise ram movement on both sides. It performs exceptionally well under harsh conditions, such as eccentric loading, and requires simple maintenance along with relatively low purchase and operating costs. This design is ideal for batch bending of medium-thick plates where extreme precision is not critical.Performance Benefits
High-Efficiency Processing for Medium & Thin Sheet
Designed with a high-rigidity mechanical synchronisation structure, this machine delivers stable performance, easy maintenance, and low operating costs. It is ideal for bending medium and thin sheets used in heavy cabinets, structural components, and general machinery.
- Bending force: 400-4000kN
- Effective bending length: 1600-4100mm
- Max. bending speed: 10mm/s
- Opening height: 430-485mm
High-Rigidity Mechanical Structure
A high-strength torsion shaft runs the full length of the ram, serving as the core mechanical synchronisation mechanism. Linked at both ends to the left and right screw drives or hydraulic cylinders, it ensures excellent synchronisation and structural integrity during ram movement.
Simplified and Reliable Hydraulic System
Synchronisation does not rely on servo valves or closed-loop feedback. The hydraulic system has a simple design, mainly using proportional or conventional hydraulic valves, with lower requirements for oil cleanliness. This results in easier maintenance and higher reliability.
High-Strength Monolithic Machine Frame
The frame is formed as a single piece, providing ample tensile and compressive strength while keeping table deflection within safe limits. Stress is relieved through annealing, and precision machining is completed in a single pass on a large gantry milling machine to ensure excellent straightness and perpendicularity.
Flexible Manual Front Support Module
The front support features roller supports that slide manually left and right along Z-axis linear guides. Height adjustments are made easily via a handwheel, providing flexible and reliable material support.
High-Precision Backgauge Module
The backgauge uses a high-precision worm-gear transmission system for fast X-axis movement. Anti-collision backgauge fingers are designed for quick replacement, ensuring convenient maintenance and long-term operation.
Wide Range of Tooling Options
A broad selection of upper and lower tools is available to accommodate diverse bending applications and process requirements.
Quick-Clamping System
The upper tool incorporates a quick-clamping system for fast and easy tool changes, significantly reducing setup time and improving productivity.
Stable, High-Quality Oil Pump
The oil pump has a high-strength cast iron housing with an integrated noise-reduction design. It delivers stable performance, strong resistance to oil contamination, and a long service life.
