OAK CSE-M590-950 Vertical Expander : 

OAK VERTICAL EXPANDER
The OAK line of tube expanders feature machines dedicated to dependably expand heat exchange coils with little damage. Accuracy and precision during tube entry and exit ensure that tubes are expanded uniformly, and fins remain unharmed. Higher production rates are made possible by the short cycle time. The coil lift and eject systems assist in operator safety and ergonomics.

MECHANICAL EXPANDERS
The vertical mechanical expander is designed specifically for the production of high-quality heat exchanger coils.
The short cycle time allows for both mass production environments and flexible, short run situations.
A standard expander package may include the following:
■ Compact Design
■ Standard Lift with Fixed Enclosures
■ Self-Storing Backplates
■ Rod Short-Out System
■ Final Expander Support Mechanism
■ Coil Eject
■ Hydraulic Cooling System (Oil to Air)

Economic Advantages
■ Expansion speeds over 50 fpm, means a 36” (914 mm) coil can be expanded in 15 seconds or 120” (3 m) coil in 35 seconds.
■ All tubes can be expanded in a single cycle.
■ Customized options for short- or long-run production environments.

Technical Advantages
■ Structure is designed for a specific task: accuracy and longevity.
■ 5 mm to 1” (25.4 mm) diameter tubing, coil widths up to 60” (1,524 mm) standard or 72” (1,828 mm) special.
■ Rod short-out system prevents damage before it occurs by detecting expander rod buckling, saving perishable tooling scrap and coils.
■ Coil length is repeatable to 1/16” (1.5 mm).
■ Many options to enhance production rate & operator ergonomics: coil handling, coil movement and coil containment during expansion.
■ Auto-rod option reduces set-up time.
User Advantages
■ Touch screen auto setup of coil height control ensures consistent, repeatable, part-specific setups vs. operator-based setups.
■ Touch screen based auto rod pattern reduces changeover time.
■ Coil eject system pushes coil out after expansion.
■ Operator touch screen controls can be configured for different languages.
