The Model AHBBQ/SL Qual-Ekon Hairpin Bender/Straightener is a fully automatic machine that will either bend 180 degree hairpin bends or feed, straighten and cut to length copper or aluminum tubes from level wound rolls. This machine processes two tubes pre cycle and uses a hitch type feed system with a chip free orbital cutoff.
The production application of the TRIDAN Model AHBV-4 is to produce hairpin bends from level-wound coiled tubing of copper or aluminum. It is a fully integrated system consisting of a Tube Straightening, Sizing, and Lubrication Section, adjustable-length Tube Feeding Section, a chipless Tube Cutoff Section, and Hairpin Bender Section. Supporting equipment include a Tube Decoiling System.
The Control System is designed in such a manner that all operations are sequenced fully automatically or may be individually placed under manual control. The Tube Straightening, Feeding, and Cutoff Sections are mounted on a machined base plate, which also serves as the top of the weldment-constructed hydraulic reservoir. This over-sized reservoir is an integral part of the machine's frame, and is furnished as standard with a liquid level gauge and thermometer.
The Hairpin Bender Section is mounted on a heavy-duty fully machined base frame to insure positive alignment with the Tube Straightening, Feeding, and Cutoff Section under all setup and operational conditions. The Bender Section is precisely guided on the base frame, again to insure alignment between the tubes and the bending mandrels and mandrel rods. The Tube Decoiling System is built on a weldment frame of sufficient size and rigidity to support the number and size of coils dictated by the application. The Tube Runnout System is designed to provide support for the tubing during it’s feeding when the AHBQB/SL-4 is used in the straight length mode.
