  1. Using Cleaner Technology for a Brighter Factory

    Comments Off on Using Cleaner Technology for a Brighter Factory

    Outdated Hydraulic systems require constant maintenance and high cost pumps, Pure Pneumatic systems lack the force and controllability, Arbor Presses and Hammers exhaust my employees, Flywheels are dangerous; if these problems sound familiar you’re not alone. Why not use a clean, reliable, consistent & cost-effective product to REPLACE all of these? The Solution is HyperCyl!

    In most automated assembly applications which can be insertion, piercing, forming or assembling, the key ingredients to a successful project are precision, accuracy and repeatability. Continuous Quality Control over these processes that can determine good/bad parts while in motion is the new norm. HyperCyl-EMA, HyperCyl hydra-pneumatic & HyperView-Press are just a few of the options that have made HyperCyl a one-stop solution provider for over 25 years.

    *HyperCyl-EMA (electro-mechanical actuator) is a robust, servo driven actuator designed for precision assembly applications or applications not suited for standard HyperCyl products. Available in both Roller Screw and Ball Screw configurations with load ratings from 5kN to 230kN (1-25 tons), HyperCyl-EMA provides a new level of price/performance in the automotive, aerospace, DOD, appliance, medical, electronics and transportation industries covering a wide range of applications. Capable of extremely high rates of repeatability and up to 500mm/sec ram speeds, HyperCyl-EMA provides the performance and flexibility required in both current and future manufacturing environments and, it’s built in the USA.

    *HyperCyl (hydra-pneumatic cylinder) is a low cost air/oil solution that can replace outdated technologies with a more precise, controllable stroke. Not your grandfathers air/oil unit, we have re-packaged the 3-piece air/oil design into a single self-contained unit ready for use upon shipment. Available from 5kN to 1,780kN (1-200 Tons) using ONLY shop air, HyperCyl provides a long-life cylinder that is simple to maintain, runs on 2 pneumatic valves, requires no drip pans or expensive cooling systems but also boasts a LIFETIME warranty.

    *Available for both the EMA and HyperCyl is the HyperView-Press signature analysis controller. Precise force/distance monitoring coupled with trending, data logging, Cpk and data analysis capabilities will profoundly improve finished product quality and substantially reduce manufacturing costs. During the cycle, the unit gathers information from the Inputs (Analog or Encoder) and provides a wave-form curve with user-adjustable windows indicating what a Valid/Good part is. The “Window 7” embedded software provides the best of both worlds: ease of use/setup and the deployment simplicity of an off-the-shelf solution tailored to your exact press monitoring requirements.

  2. 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.

  4. 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.
