The TRIDAN® Model REXQ Combination Automatic Return, Elbow, and Dual 90° Crossover Bender is one of a family of three benders built by TRIDAN® that will produce return bends. The REXQ will produce up to two bent tubes per cycle, dependent on tube diameter.
Other models are the RBQ Return Bender which produces up to two (2) return bends per cycle and the RBV Return Bender produces up to six (6) return bends per cycle. Both dependent upon the tubing’s diameter.
With TRIDAN’s development of the REXQ, it is now possible for all coil manufactures to produce their own dual 90° Crossovers and Elbows; and lower-to-moderate volume manufacturer are provided a single source machine for all their connection tubing parts.
GENERAL MACHINE DESCRIPTION:
The production application of the TRIDAN® Model REXQ is fabricate short 180° bends, known as return bends; elbows, 5° to 90°; dual 90° crossover bends; and 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.
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 Uncoiling 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 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 Uncoiling System is built on a weldment frame of sufficient size and rigidity to support the number and size of coils dictated by the application.
