3-ROLL VARIABLE AXIS PLATE BENDING MACHINE

A 3-roll variable-axis plate rolling machine operating principle is conceptually similar to that of a press-brake, with the top roll pressing the plate between the two side rolls. However, a 3-roll bending machine is much more flexible and accurate, being able to vary the interaxis distance between the bottom rolls. In this regard, DAVI MAV allows for individual, horizontal movement of both side rolls and vertical movement of the top roll. Furthermore, each one of the 3 rolls features rotation drives and can be tilted in every direction for cone bending.

DAVI MCB 4-ROLL PLATE BENDING MACHINE

Whenever repeatability, productivityand ease of use are of essence, the 4-roll is the technology of choice. In a 4-roll machine, latest development of the rolling technology, the bottom roll clamps the plate guaranteeing a perfect control over its position throughout the whole forming process. The side rolls, actuated by the unique DAVI planetary guides technology, provide the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy thanks to the perfect parallelism offered by the patented Servo-Tronic© system. Compared to other technologies, 4-roll machines stand out for allowing fully CNC-automated production processes, significantly decreasing the reliance on operators’ skills and, hence, making it the most suitable tech for mass-production.

DAVI MCP - 3-ROLL DOUBLE PINCH ANGLE ROLL MACHINE

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.
