Rotary draw bender with internal mandrel

CML USA supplies a wide range of Ercolina pipe benders, tube benders and tooling for round or square tube, including the Megabender ® 030 rotary draw bender with internal mandrel. Ercolina’s patented mandrel system adapts easily to the Megabender 030 without

Traditional mandrel machines require high volume production to be cost effective. The Ercolina system is an inexpensive alternative to high volume systems, making it suitable for prototype or production runs requiring up to 1,000 bends per day. The Megabender’s main drive unit is electromechanical, which improves reliability and reduces the cost and maintenance requirements associated with more expensive completely hyd- raulic systems. The simple hydraulic system operates only the clamp die, pressure die and mandrel extractor. Ercolina’s standardmicro- processor controls clamping, mandrel movement, bending speed, bending angle and material spring back compensation functions for true NC semi- automatic three axis operation. Newly redesigned mandrel tables are available in 5, 10 or 20ft lengths, to accommodate most applications.

bends, the Ercolina mandrel system can accommodate centreline bend radii as small as 1.5 times the external diameter, on tube diameters ranging from 3 / 8 " to 3". Mandrel bend systems incorporate six separate tools to effectively support the profile during the bending process. The six tools are the centre former, pressure die, clamping die, wiper die, collet and internal mandrel, and are specific to material type and dimension. Omni-X Inc, USA and Czech Republic, is the manufacturer of high precision and performance tube bending tooling for the aerospace, automotive, shipyard, HVAC, furniture and bathroom accessory industries. The range includes bending and end forming tools for any size, make and model of tube bender and endformer on the market. Bend dies, clamp dies and pressure dies are developed using the latest software and over 80 years of combined experience in the tube bending industry. The company’s engineering department is capable of designing both simple and complex compounds and stackable multi-radius bend dies in minutes. Quick change design minimizes downtime between tool changes, grip sections for all applications (serrated, knurled, smooth, grit-blast) and mandrel- less tooling.
