The TRIDAN® Model RSL Combination Automatic Return Bend Sizer & Brazing Ring Loader is one of two return bend sizers built by TRIDAN®. The other sizer is the Model ARS, which performs only the return bend sizing function. The RSL is designed to meet the requirements and needs of the coil manufacture who wishes to employ an automatic brazing process for the joining of return bends to the tubes in heat transfer coils.
GENERAL MACHINE DESCRIPTION:
The production application of the TRIDAN® Model RSL is to in a fully automatic manner:
1.) Round (size) the tangent legs of return bends.
2.) Apply the solder (brazing) ring to the sized tangent legs of the return bends.
It is designed to accept either copper or aluminum return bends or having outside tube diameters between 5/16″(7.94mm) and 3/4″(19.05mm).
The RSL is a fully integrated system consisting of the Rotary Index Table, Return Bend Feeding System, Return Bend Sizing System, Brazing Ring Feeding System, Brazing Ring Loading System, and Ejection 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 Rotary Index Table, Return Bend and Brazing Ring Feeding and Loading Systems are mounted on a machined base plate, which is supported by a weldment constructed tubular steel frame. The hydraulic reservoir is integrated into this frame, and is furnished with a liquid level gauge and thermometer.
