Roper Whitney Magnabend

Electromagnetic Sheet Metal Bending BrakeThe Roper Whitney Magnabend offers performance characteristics no conventional bending brake can match. The unique electromagnetic design of the keeper clamping system allows you to form many complex shapes not possible before. Plus, Magnabend can handle all regular shapes in light ferrous and non-ferrous sheet metal (up to 4' wide, 18 ga.) in a simpler, less time consuming and efficient manner.The rugged simple construction incorporating only one moving part assures low maintenance and versatility for all light duty forming requirements.A wide variety of complex shapes can be formed with Magnabend. These include rolled edges up 330°, partial length bends, closed shapes, unlimited depth for boxes and heavier material bends (up to 10 ga.) in shorter widths.Model MBB 4181 SpecificationsInput Voltage: 115V, single phase, 60 hertz. Input current: 12 amps. Duty cycle: 20%Maximum Bend Length: 49.38" - or 51" with manual location of keeper.Full Length Bend Capacity: With 1.5" lip (extension piece fitted to bending beam) 18 Ga. in mild steel or non-ferrous material. (Typical Bend Radius - .16")Minimum Reverse Bend: 1.5" with work support; .75" without work support.Keepers (Clamping Members): Both models furnished with 11 keepers - 3/4", 1", 1 3/8", 1 7/8", 2 3/4", 3 3/4", 4 3/4", 6", 12", 21 5/8", and full length 51 1/4".Net Weight: 275 lbs. (Shipping weight 300 lbs.)Design Features Assure QualitySimplicity is evident in Magnabend's electromagnetic design which eliminates a conventional upper beam and more complex finger arrangements. Keepers (clamping members) are simply positioned over the workpiece and are clamped in place electromagnetically when the bending beam is raised. Keepers self-adjust for material thickness as the apron moves.Electromagnetic Design Magnabend - Designed to eliminate the hindrance of an upper beam with the introduction of an elongated electromagnet and keeper system.Self Locating - A simple and effective method of locating the full length keeper is achieved by spring-loaded steel locator balls.Triple Hinge System - Three hinges allow Magnabend to have a lighter bending beam without limiting durability and reliability.Bend-Angle Gauge - Convenient bend angle gauge features adjustable stop for precise, efficient repeat bends.Back Gauge - Production efficiency in repeat bends is provided by adjustable back gauge.Safety Features - The safety button engages a light magnetic force on the keeper. As well as a safety device, this force is a convenient way to stabilize the work piece for precise measurement before you activate full clamping power.
