Innovative GB90/GB100 mandrel tube and pipe bender

Ercolina, USA, has launched the GB90/ GB100 semi-automatic Giga Bender mandrel machine for large radii tooling up to 16” CLR. The bender is ideal for bending tube, pipe, square and rectangular profiles to centreline radius as tight as 1.5D. The interactive PLC touchscreen offers easy access to auto and manual operating modes, system diagnostics and multiple language capability. The heavy steel structure of the GB90/GB100 provides a rigid platform and minimizes vibration. The machine is complete with a high capacity hydraulic reservoir with automatic cooling system. The GB90/GB100 offers programmable bend angles with an independent material springback setting for each bend. Programmable auto mandrel positioning allows the operator to optimize extraction for improved bend quality. Clamping, pressure die and boost movements are programmable with a manual override. Convenient USB connectivity is available for unlimited program memory storage and communication.

The machines are available with full CNC (6) axis control, with precision encoders on each axis ensuring highly accurate bending. This accuracy is highlighted by the interactive touchscreen that displays absolute (ABS) or incremental (INC) positioning with inch or metric readout. In addition, a programmable tail stock interference zone monitors position and eliminates workhead collision. The bender accepts YBC and XYZ input values.

Standard hydraulic ports accept Ercolina’s patented (KST) clam shell or (FST) finger clamp systems. The hand-held remote bending control is certified class 3 safety and all electrical components are UL, CSA and CE approved.

Application fields include chemical and petrochemical industries, ammonia and urea systems, fertilising and refinery plants. The new technology creates a unique bimetallic tube from two distinct tubes of different materials. The main advantage of this kind of tube is the possibility to join together two materials with different mechanical properties and with opposite aims. For example, the first material (inner or outer) could be a high corrosion resistant alloy (eg copper, aluminium-brass, zirconium) and the second one a high stress resistant alloy (such as steel, stainless steel, iron, duplex, titanium). The new manufacturing technology is designed to be cheap and fast, and the production method is easy to carry out.
