TPT November 2007

In the production of extremely thin walled welded tubes the coil is often drawn to shape rather than roll formed. With the latest version of Copra ® RF, it is also possible to integrate the drawing dies within a roll forming tool set. This allows the analysis of the complete forming process and to predict and optimise the final tube’s properties. œ

to 76mm diameter for most applications, with minimal cycle times. The shear blade is fabricated from high impact steel for maximum durability, and the simple design of the head and electrical components provides increased accessibility for fast tool changes. The machine to be displayed will feature Eagle’s optional ‘double-cut’ feature, which reduces the dimple usually associated with a stab cutting operation. An I/O 3000 inside/outside sizing machine will also be on show. The I/O 3000 is one of the company’s next generation tube end- formers with all-electric operation (ie no hydraulics). The all-electric design of this machine results in clean, quiet tube sizing. A programmable control provides menu driven programs and enables data storage of 250 parts. All Eagle CNC tube bending machines on display will be operated using BendPro G2, the company’s latest bender control software, which provides a compact and powerful bending machine control solution, through an easy to use Windows interface.

EFD Induction AS Norway Booth 23037

EFD Induction develops, commercialises and supplies complete industrial heating processes, including power sources, mechanical handling equipment and control systems based on the latest IT technology. EFD Induction has emerged as a pioneer in finding new induction heating applications and solutions. The Weldac G2 is the company’s family of high-output solid-state welders. It is available with output power of 150-2,000kW and with 100, 200 and 300kHz nominal frequencies. The Weldac uses rugged IGBT transistors, which due to EFD’s patented switching pattern, can now be used in high-frequency applications, such as tube welding. IGBT transistors are virtually short- circuit proof, making the Weldac a very reliable and robust equipment that will give more uptime and more output.

Eagle Precision Canada Booth 23071

Eagle will exhibit some of its latest equipment and tooling at the show, as well as highlighting its cell automation and integration capabilities. Equipment being shown will include EPT-10 (½") and EPT- 25 (1") CNC tube benders. The EPT-10 is a fully programmable, 3-axis machine featuring a servo motor for all axes including the bend arm, providing accurate and quiet operation. Eagle will display the EPT-10 integrated to a Motoman robot to highlight some of the automation and integration options available.

The EPT-25 is a fully programmable, 3-axis machine capable of both empty and mandrel bending. The standard EPT-25 is designed to handle 1" diameter tubing. The machine being displayed will include Eagle’s new optional roll bending package. In addition to manufacturing new equipment Eagle offers a full spectrum of upgrade, modernisation and re-manufacturing services. A re-manufactured CL-300 tube bender with 3-axis CNC upgrade will be exhibited at the show. The CL-300 tube bender is an example of the various upgrade and retrofit packages that Eagle has designed for older single axis machines to convert to full 3-axis CNC capability. Also on display will be a TC-2000 tube cut- off machine, capable of cutting tubing up

Apart from capitalising on the strengths of standardised IGBT transistors across the entire frequency range, the Weldac G2 system also provides continuous electronic load matching. Continuous electronic load matching secures full power output across a wide range of tube sizes, ensuring maximum welding speed for each size. The Weldac eliminates the need for costly compensation capacitors by using diode rectifiers that result in a high, constant power factor (0.95) at all power levels. Test-verified efficiency from input at the rectifier to output at the coil is 85–87 per cent. Cooling water consumption is low, with no need for expensive de-ionized water.
