  1. How To: Determine the Appropriate Technology for High Force/High Speed Applications

    Comments Off on How To: Determine the Appropriate Technology for High Force/High Speed Applications

    Flexibility, performance, capital and operating costs have always been key factors in today’s expanding manufacturing marketplace. For decades hydraulics and mechanical presses were the only options for high-speed, high-force assembly and forming applications. More recently hydra-pneumatics and servo-based systems have emerged as viable low-cost alternatives. So which technology is best suited for a specific application? The following topics can serve as a guideline towards the correct usage.
    Aries Engineering is the only manufacturer Headquartered and Manufactured in North America offering both servo driven and hydra-pneumatic solutions.

    Servo-Based Technology – HyperCyl-EMA

    Capability: Provides exceptional control over force, speed, and distance characteristics. Requires the use of a full PLC/PC based electrical panel and 230V/460V. Best used for push-to-distance or push-to-force applications, push/pull applications and where Extreme repeatability is essential. Signature analysis, data logging, part history, trending and root cause analysis options are also available for added functionality and tracking.

    Reliability: Servo technologies are inherently capable and sizing them appropriately is crucial. Expected lifetime is from 3 Years to 5 Years, configured for any application. Long-Term Reliability coincides with maintenance schedules.

    Speed: Up to 16.00 in/sec with an extremely high rate of repeatability. Requires a deceleration setting before Contact and Home to maximize tooling and screw life.

    Forces: 1-10 Ton in Ball Screw configurations (BS1 & BS2) with a medium dynamic load rating; 1-25 Tons in the Roller Screw configuration with a high dynamic load rating.

    Maintenance: 3/6-month lube schedule & periodic belt tension check dependent on usage and environment.

    Cost: Can be higher initial cost than comparable Hydraulics. Energy efficiency and ROI achieved with minimal downtime, low noise pollution, rapid setting changes without involving tooling, ZERO environmental pollution, comparable energy usage to hydraulics without the mess.

    Hydra-Pneumatic Cylinders – HyperCyl

    Capability: Utilizing 2 pneumatic valves for operation and a FRL greatly reduces start up time. Cylinders are available in 5 design configurations and 11 standard sizes. Best used for; crimping, dimpling, peening, swaging, inserting, clinching, pressing, staking, piercing, punching, marking, bending, and forming. When coupled with the IntelliCyl option, (load cell and LVLT) force distance monitoring is available.

    Reliability: (MTBS) Mean time between service interval of approximately 4-5 million cycles because down time is not an option. LIFETIME warranty on all HPI – HPS – HZ – HZS – HPT cylinders, 1-Ton through 200-Ton.

    Speed: Fast Approach speeds similar to that of a pneumatic cylinder (6 in/sec – 10 in/sec) and High-Pressure speeds similar to that of hydraulic cylinders (1.0 in/sec – 2.0 in/sec).

    Forces: 1-200 tons of output force using 30-100 PSI shop air.

    Maintenance: 20 million cycles before seals require replacement. Field serviceable by maintenance techs and 24-hour HyperCyl assistance is available. Periodic maintenance depends on application and environment.

    Cost: More expensive than Pneumatic cylinders but offers the same clean, quiet & self-contained operation. Less expensive than hydraulic and mechanical systems for both short & long-term investments.

  3. What Is a Servo Actuator?

    Comments Off on What Is a Servo Actuator?

    Actuators are designed to convert energy from different sources, such as electric currents, pneumatic pressure, or hydraulic fluid pressure, into motion. There are three main types of actuators: pneumatic actuators, hydraulic actuators, and servo actuators.

    Servo actuators use feedback signals to move or control mechanical systems in a highly efficient and safe manner. This is possible because servo actuators have a controller that can accurately compare, contrast, and calculate the potential differences between the desired results and system conditions on a real-time basis before the motion starts.

    Servo actuators use a servo motor in either an open or closed-loop control system. Several servo actuator models have a food-grade approved coating of paint for more sanitary wash-down applications.

    Servo actuators are available in both ball and roller screw configurations, like the HyperCyl-EMA, which has several options available for output force. They have an extended service life because they can easily be re-lubricated without disassembly.

    How Does a Servo Actuator Work?

    A servo system has three main core components:

    • A controlled device that allows the actuator to successfully operate
    • An output sensor/signal that acts as the main controller to tell the device what to do
    • A position sensor, encoder feedback, or load cell to provide accurate system feedback readings

    Servo Actuator Control Systems

    The control systems, which allow the actuators to operate, come in two different designs.

    Closed-Loop Control System

    Commonly referred to as feedback controllers, this type of control system is fully automatic and uses the input of the system and the output of the system controls to function. Closed-loop control systems are usually very accurate.

    Open-Loop Control System

    Commonly referred to as a non-feedback system, this type of control system is not automatic and doesn’t have a feedback loop. The output of the system depends on the input. However, the input or controller is independent of the output produced by the system. Open-loop systems do not measure the device’s output or use the information as input for further consideration.

    How Do Servo Actuator Controls Work?

    Servo actuators are controlled by a feedback signal generated by comparing the output signal and the reference-input signal rather than a variable-input signal. Whenever a command or reference-input signal is applied to the system, it is immediately compared with the system’s output-reference signal produced by the output sensor. Lastly, a third signal is produced by the servo actuator’s feedback system before it starts to move.

    The device can also be programmed with certain instructions and autonomously perform the movements on its own. For example, the actuator can receive a command to go to a specific position and immediately follow the command. This makes them very different from comparable pneumatic valves (pneumatic actuators) and pumps (hydraulic actuators), which can only follow simple instructions to ‘power on’ or ‘power off’ on their own.

    Applications of Servo Actuators

    There are numerous applications of servo actuators. Some of these include toys, home electronics, computers, drones, and remote controlled cars.

    Servo actuators also often play a crucial role in the function of both land- and sea-based vehicles – such as automobiles, airplanes, helicopters, and submarines.

    Automobiles

    Servo actuators can contribute to the function of these parts in automobiles:

    • Engine Cradle Assembly
    • Engine Sub-Assembly
    • Ball Joints and Bushings

    Airplanes and Helicopters

    Servo actuators adjust the wing angle of airplanes and control steering by moving the levers back and forth. Airplanes can easily “fly-by-wire” when they have a servo-controlled main system instead of an older hydraulic-powered one.

    Servo actuators can also control the speed of a helicopter by moving a swash plate, which can tilt the pitch of the blades in a certain direction to give it more lift.

    Submarines

    Servo actuators can adjust the submarine’s steering, bay doors, hatches, and rudder.
