Vertical Arbor Coil Forming

OAK coil form machines produce high-quality distortion-free bends in coils. Recent innovations provide the ability to make bends that were previously impossible when using very low-strength, enhanced fin designs. These machines will form single row coils or multiple single-row coils joined at one end.

The vertical arbor coil form machine incorporates a single, vertically oriented bend arbor that produces one, two, or three 90° bends, which create L-, U-, or box-shaped coils. The cycle time required to produce a single bend - after the coil has been loaded and positioned - is approximately 10 seconds. The vertical arbor technique leaves the mechanical bond between the fin and tube undisturbed, ensuring maximum heat transfer.

  • Economic
    • All electric operation lowers energy consumption and provides greater precision than hydraulic machines
    • Electric drive requires less maintenance than hydraulic machines
    • RFID technology matches part data to arbor cover, prevents forming the wrong radius and reduces expensive scrap
    • Reduced cycle time of ~10 seconds per bend increases productivity
    Technical
    • Forms round and flat-tube coils up to 60" wide and 118" long
    • Soft surface arbors enable tighter bends without fin damage
    • Forms bends up to a total of 200°
    • Forms radii as small as 2¼" (57 mm) and as large as 18" (457 mm)
    • Can form up to three 90° bends or more if bends are less than 90°
    User
    • Single operator operation: Single operator can load flat coil on table and start the machine, machine will automatically position coil(s) for each bend, perform the operation, and present the finished coil upon completion
    • Optional bar code scanner prevents forming incorrect stock
    • Optional coil loading table allows machine to cycle while operator loads next coil
    • Ability to offload coils onto a table or conveyor system
    • Operator touch screen controls can be configured for different languages and feature part recipes
