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 with relatively low purchase and operating costs. This design is well-suited for batch bending of medium-thick plates where extreme precision is not critical.
Performance Benefits
High-Efficiency Processing for Medium & Thin Sheet
Built with a high-rigidity mechanical synchronisation structure, this machine delivers stable performance, simple 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. Connected to the left and right screw drives or hydraulic cylinders via linkages at both ends, it ensures excellent synchronisation and structural integrity throughout ram movement.
Simplified and Reliable Hydraulic System
Synchronisation operates independently of servo valves or closed-loop feedback. The hydraulic system uses a straightforward design, mainly employing proportional or conventional hydraulic valves. This reduces oil cleanliness requirements, making maintenance easier and improving overall reliability.
High-Strength Monolithic Machine Frame
The machine frame is manufactured as a single piece, providing robust 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, ensuring excellent straightness and perpendicularity.
Flexible Manual Front Support Module
The front support includes roller supports that slide manually left and right along linear guides on the Z-axis. Height adjustment is easily achieved via a handwheel, providing reliable and flexible material support.
High-Precision Backgauge Module
The backgauge features a high-precision worm-gear transmission system for fast X-axis movement. Anti-collision backgauge fingers are designed for quick replacement, facilitating maintenance and long-term operation.
Wide Range of Tooling Options
A wide selection of upper and lower tools is available to accommodate diverse bending applications and process requirements.
Quick-Clamping System
The upper tool includes a quick-clamping system for rapid, easy tool changes, significantly reducing setup time and boosting 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.
