Upgrading Air-Over-Oil Cylinders with the H-Series SMART Electro-Hydraulic Actuator

Air-Over-Oil Cylinders

Air-Over-Oil cylinders are often used in Press applications. Examples include:

• Assembly presses
• Metal forming – Various processes:
  • Bending
  • Staking
  • Punching and Piercing
  • Coining
  • Swaging
• Composite forming presses
• And many others…

Air-Over-Oil cylinders incorporate a fast extend stroke, slow load stroke, and fast retract stroke however, there are a number of disadvantages with Air-Over-Oil technology including:

• Operate using inefficient compressed air resulting in high energy consumption
• Control of position and applied force is difficult and not precise
• Require significant maintenance and create unscheduled downtime
• Leaky seals result in drifting and not holding position
• Do not allow programmable acceleration/deceleration profiles that avoid damaging material and tooling

Kyntronics H-Series SHA Advantages:

• All Electric: eliminates pneumatic and hydraulic connections.
• All-In-One Solution: high-speed and high-force actuator in an integrated package.
• Energy Savings: only uses power on demand - eliminates the requirement for compressed air.
• Precision: precise control of position force, accel/decel and speed – provides quality cycle pass/fail data and reduces tool wear.
• Programmable: fully programmable extend stroke, load stroke and retract stroke, reduces cycle time.
• Minimal maintenance: totally-sealed system eliminates leaks and contamination.
