Because of variability in processed parts, required accuracy, output volume, etc. each industrial sector requires dedicated manufacturing strategies. When it comes to section bending, such strategies must be accommodated by selecting the right machine based on the specific application. Thanks to the wide range of available angle roll machines, DAVI can offer the most suitable machine for any application. Depending on machine capacity, a 3-roll double pinch machine can operate in two different ways: with horizontal shafts: usual configuration for small machines, allowing for simpler operation due to easy handling of small sections; with vertical shafts: usual configuration for large machines, required to be able to simplify handling of heavy sections by bending them parallel to the ground. Regardless the configuration, DAVI MCP 3-roll machines feature two side rolls moving against the fixed top roll. The side rolls, actuated by planetary guides technology, provide the necessary bending force achieving tight diameters per capacity while obtaining high accuracy.
Improved Handling and Safer Operations thanks to 3 Motorized Rolls as standard
Particularly on a 3-roll machine, it is to hold as much grip as possible on the sections. Featuring three independent motors driving each individual roll as standard, DAVI all-rolls-drive technology guarantees the optimum torque transmission to the sections and distribution between hydraulic motors. Thanks to this system: rolls speed on each roll will be automatically and hydraulically synchronized; the risk of section slipping/falling during the bending process is highly reduced; Turbo and Turbo Booster Rolling speed can be installed on demand.
Maximum Flexibility thanks to exclusive DAVI Torque Management System (DTMS)
Unlike other solutions available on the Market, provisioning a single hydraulic motor driving the three rolls, DAVI MCP features three independent hydraulic motors driving each individual roll. This arrangement, in conjunction with the DAVI exclusive Torque Management System, allows for a perfect control of the overall available machine power. Specifically, the system guarantees: the lowest amount of slippage between rolls and section, for the highest transmission efficiency (avoiding power losses); a low chance of section getting stuck while bending. Whenever higher degree of precision and performance is required, the machine can be provisioned with a technologically superior hydraulic unit capable of: transferring the highest amount of torque where needed (getting out of difficulties balancing the torque for example in case of different torques needed on the three rolls); synchronizing all the rolls contact speed, even in case of tools with different outer diameter.
