Other models are the Model RBV-1 Return Bender which produces up to six (6) return bends per cycle. As well as the Model REXQ-4 Combination Return and others it has the same capacity specifications as the RBQ-4. However, 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. They previously could not justify the cost and/or the output of return benders producing six to ten bends per cycle.
RBQ – Return Bender GENERAL MACHINE DESCRIPTION:
The production application of the TRIDAN Model RBQ-4 is to fabricate short 180-degree bends. These are also known as return bends. Short straight lengths directly from level-wound coiled tubing of copper or aluminum. Also having outside tube diameters between 1/4″ (6.35mm) and 3/4″ (19.05mm). A 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 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. Also, they may be individually placed under manual control.
The Tube Feeding/Straightening, Bending, and Cutoff/Ejection Sections are built on a machined vertical plate. In addition, it 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. Finally, contact us today to place your order.
