DAVI 4-ROLLS Plate Bending Machine Mca 2017

  

Benefits

· The most accurate, easy to operate and fast plate roll configuration in the market

· The flat end is the shortest (excellent prebending) thanks to the clamp that can take the edge to the precise tangent

· No need to prebend both ends before starting to roll as required with a 3 roll double pinch

· It is the easiest machine to roll a plate, as it requires one only position for each side bending roll

· The entire plate can be finished in one pass only (on a suitable capacity) including prebending of both edges

· No need to remove, turn and re-insert the plate as on a 3 roll asymmetrical single pinch

· The most suitable to be CNC operated, as the plate is always under control clamped between the top and bottom rolls until the part is finished

Features

· Machine engineered, built, checked, tested and guaranteed according to the strict ISO 2008:9001

· ISO 9000 certified components (the most reputed brands in the market)

· ISO 9000 top certified subcontractors (the best know-how, expertise and quality available)

· Hydrautronic

· Digital, electronic synchronised fully hydraulic machine

· Exclusive Roll by Wire digital technology (much faster, accurate and reliable)

· Servo-Tronic parallel system the most accurate and reliable (0.1 tolerance)

· Guiding The Side Rolls

· Planetary guides system for side roll movement (no linear guides affected by friction

· Self aligning (double crown) heavy duty, largely dimensioned roller bearing for rolls rotation

· Rolls Rotation

· 2 powered rolls by means of 2 planetary gearboxes coupled with 2 hydraulic motors

· Hydraulic instant stop rotation brakes to improve the safety, avoiding unexpected movements of the rolls during pre-bending

· Hydraulic protection againts oveload (the hydraulic pressure is limited to safety level)

· Hydraulic System

· Hydraulic unit (Rexroth, Parker or Vickers type) including electric motors, hydraulic pumps, solenoid valves ini manifold to prevent oil leaks, protecting safety systems from oveloads

· Rolls with multiple speeds, pre-selectable by the console

· Hydraulic operated drop end Yoke
