Torsion Axis Press Brake Machine

A torsion axis press brake is a machine used for bending metal sheets, utilizing a synchronized mechanical system to ensure precision. Its key component is a torsion bar (or shaft) connecting two hydraulic cylinders on either side of the machine. When activated, hydraulic pressure drives the cylinders upward, creating torque in the torsion bar. This torque forces the upper beam (ram) to descend uniformly, pressing the metal against a die to form a precise bend. The torsion bar mechanically synchronizes the cylinders, maintaining parallelism between the ram and the bed during operation. This design offers simplicity, durability, and cost-efficiency compared to CNC servo-driven models, making it ideal for repetitive bends in small-to-medium workshops. Adjustments are typically manual, focusing on bend angle and depth.

Torsion axis press brakes offer distinct advantages in metal fabrication. Their torsion bar synchronization mechanism ensures uniform force distribution across the ram, enabling high-precision bending with consistent angular accuracy (±0.5°), particularly beneficial for complex or long workpieces. This rigid construction minimizes deflection, maintaining parallelism between upper and lower dies even under heavy loads (up to 3000 tons). Operators benefit from simplified programming with angle-memory systems that automatically calculate required tonnage, reducing setup time by 30-40% compared to conventional presses. The direct-drive transmission eliminates hydraulic components, cutting energy consumption by 25% while achieving faster stroke cycles (15-20 RPM). Enhanced durability comes from reduced wear components, lowering maintenance costs by approximately 50% over hydraulic equivalents. These machines particularly excel in high-volume production of automotive chassis and architectural metalwork, where repeatable precision is critical.
