DAVI Full Hydraulic Plate Roll Model Mcb F-30

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

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)
• 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)
• 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
• 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 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
