Rotary Draw Bender features internal mandrel.

Press Release Summary:



Mega-Bender® 030 uses mandrel system to produce bends on tubes and hollow profiles. Depending on material, wall thickness, and distance between bends, mandrel can accommodate centerline bend radiuses as small as 1.3 x OD on tube diameters from 3/8-3 in. Mandrel system incorporates 5 separate tools and produces up to 1,000 bends/day. Bender features electromechanical drive and microprocessor control for NC semi-automatic, 3-axis operation.

Rotary Draw Bender Model Mega-Bender 030 with Internal Mandrel



Ercolina's® patented mandrel system adapts easily to the Mega-bender® 030 without modification to produce high quality bends on tubes and hollow profiles when non-mandrel systems are no longer effective. Depending on the material, wall thickness and distance between bends the Ercolina® mandrel system can accommodate centerline bend radiuses as small as 1.3 times the external diameter on tube diameters ranging from 3/8" to 3". Mandrel bend systems incorporate five separate tools to effectively support the profile during the bending process. The five tools are the center former, pressure die, clamping die, wiper die and internal mandrel and are specific to each tube diameter. Traditional mandrel machines require high volume production to be cost effective. The Ercolina® mandrel system is inexpensive alternative to high volume systems making it ideal for prototype or production runs up to 1000 bends daily.

The Mega-bender's ® main drive unit is electromechanical improving reliability and further reducing the cost and maintenance requirements associated with more expensive all hydraulic systems. Our hydraulic system is simple and reliable operating only the clamp die, pressure die and mandrel extractor. Ercolina's® standard micro-processor controls clamping, mandrel movement, bending speed, bending angle and material spring back compensation functions for true NC semi-automatic three axis operation. Mandrel tables are available in four different lengths up to twenty feet to accommodate most applications.
