Turnover Door Heat Exchange Vertical Tube Expanding Machine

Designed for precision forming of fin heat-exchanger components, this dedicated expander delivers integrated machining solutions tailored to heat exchanger manufacturing demands, perfectly matching the standardized production rhythm of finned heat exchanger workshops. During a single complete working cycle, the equipment consecutively completes core fabrication steps including pipe expanding, tube flaring and end flanging, eliminating repeated workpiece clamping and transitional positioning between separate processes to greatly streamline production workflows.

As a core variant within the product lineup, Vertical Tube Expander Machine adopts upright structural layout, optimizes vertical feeding and pressing stroke design, which effectively avoids workpiece offset during high-pressure pipe expansion and stabilizes machining dimensional tolerance for slender heat exchange tubes. Compared with conventional horizontal expanding equipment, matched Vertical Expander simplifies transmission assembly structure, occupies less workshop floor space and facilitates daily routine maintenance and component replacement for on-site operators.

For enterprises pursuing intelligent automated production, the configurable CNC Pipe Expander Machine version of this expander supports programmable parameter input, enabling one-click switching of different expansion specifications to adapt to diversified heat exchanger tube sizes. Merging three critical forming procedures into one-cycle processing effectively cuts auxiliary production time, improves finished product consistency, and becomes reliable processing equipment for medium and large-scale fin heat-exchanger batch production.

*Workpiece length: 1600mm , 2000mm , 2500mm , 3000mm etc , the length different , the machine specification will be different

*For the length of workpiece less than 1600mm , machine is with manual door or double rotary worktable

*For the length of workpiece more than 1600mm , machine is with turnover door oblique 84° also with the manual door which is for the workpiece length less than 1200mm

*For the length above 1600mm , the machine design is interal oil cylinder type.
