The Model RBQ-4 Qual-Ekon Return Bender is one of a family, of three return benders built by TRIDAN. The Model RBV-1 Volutron Return Bender produces up to six (6) return bends per cycle, dependent upon tube diameter. The Model REXQ-4 Qual-Ekon Combination Return, Elbow, and Dual 90 Degree Crossover Bender have the same capacity specifications as the RBQ-4; however, as the name implies, it will produce elbow and dual 90 degree crossovers in addition to return bends.
The RBQ-4 was designed specifically for the lower-to-moderate volume coil manufacturer, who previously could not justify the cost and/or the output of return benders producing six to ten bends per cycle.
GENERAL MACHINE DESCRIPTION:
The production application of the TRIDAN Model RBQ-4 is to fabricate short 180 degree bends, known as return bends, or short straight lengths directly from level-wound coiled tubing of copper or aluminum having outside tube diameters between 1/4" (6.35mm) and 3/4" (19.05mm). Random straight length of tubing may also be employed; however, the productive output will be reduced and between 12" and 16" (305/406mm) of tubing will be wasted per straight length. With an alternate control & feed cylinder design, this machine can also produce a “J” Bend (a 180 degree bends with two different leg lengths).
It is a fully integrated system consisting of an adjustable-length Tube Feeding and Straightening Section, Tube Bending Section, and Cutoff/Bend Ejection Section. Supporting equipment includes a Tube Decoiling System. The Control System is designed in such a manner that all operations are sequenced automatically or may be individually placed under manual control.
The Tube Feeding/Straightening, Bending, and Cutoff/Ejection Sections are built on a machined vertical plate, which is attached to a base plate that 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 with a liquid level gauge and thermometer, as standard equipment.
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.
