Torque Transmission
The mechanical transfer of rotational power from hydraulic or electric motors through gearboxes to the rolls, driving the plate forward under heavy load.
Technical FAQ
Heavy industrial manufacturers need the flexibility to form a wide range of extreme thicknesses and tight diameters on a single piece of machinery. A 3-roll variable-axis machine operates with a top roll that moves vertically, while the two lower side rolls move independently along a horizontal plane. This geometry allows you to increase the horizontal interaxis distance to gain massive mechanical leverage for thick plates, or narrow it to form tight, thin-walled cylinders. The Davi MAV line features full horizontal and vertical axis mobility, offering versatility comparable to a press brake but with total rolling precision.
Bending complex structural shapes with varying outer tool diameters can cause profile jamming or surface marking. DTMS is an exclusive control system that monitors and dynamically balances hydraulic power across three independent roll motors. It synchronizes the contact speed of all rolls, eliminates energy-wasting slippage, and prevents profiles from getting stuck during tight-radius forming. Integrated into the MCP series, DTMS provides precise control over available machine power.
Preventing surface damage and torque imbalances when rolling plates of varying thicknesses is critical to quality consistency. Torque synchronization automatically balances the rotational speed and hydraulic or electric power delivery between the top and side rolls. It protects the workpiece from surface friction marks, maximizes power efficiency, and prevents material distortion during complex shapes forming. Davi machines utilize automatic hydraulic or electronic synchronization circuits to match surface speed across all driven rolls under any load conditions.
Waiting for standard shipping on simple wear components during a critical production run reduces a job shop's productivity. A custom spare parts kit provides an on-site inventory of essential seals, filters, sensors, and wear items tailored to your machine model. It allows your maintenance team to replace common wear parts instantly, minimizing waiting times and protecting operational continuity. Davi stocks over 11,000 different items at its global service hubs to ensure rapid fulfillment and kit customization.
