General Information

The Model AHBVB Belt-Fed Heairpin Bender is a fully automatic machine that is used to bend thin wall tubing 180 degrees. The tubing either copper or aluminum is fed onto bending mandrels by a continues belt-type feed system. This machine also uses Tridan’s revolutionary chip free cutoff system for burrless tube ends.

The production application of the TRIDAN Model AHBVB-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, 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 automatic 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 onditions. 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.
