Winton’s line of eCNC mandrel tube benders are now available with an optional serpentine bend head. The low profile bend head provides the necessary clearance required for bending a serpentine profile.Both the swing arm that supports the clamp die and pressure die stage are designed to allow a serpentine bend to clear the dies as the dies move in and out.
The serpentine bend head also includes software features for making back to back (serpentine) bends. The figure below show the PC interface with a check box to let the controller know that a serpentine profile is being programmed. When the “serpentine” check box is active in the Window screen above, the controller automatically adjusts for the necessary clearances to form a serpentine profile.
Bending serpentine profiles—successive 180-degree bends, which typically are used in refrigeration systems—can be a challenge. By their nature, they tend to cause interference among the various bend dies, and they can be difficult to handle. Good planning in selecting a bender, planning the process, and paying close attention to infeed and outfeed options, can help make a serpentine project successful.
