Simple Solutions That Work! Issue 8

position your machine to spray from the top or side of your dies is a determination based on available space. Ceiling height and or ancillary equipment in or near the parting line using valuable square footage is a determining factor on how to spray your dies with precise control and accuracy Adjustable Base Height In spraying, adjustability to reach your parts the way they need to be sprayed is critical in preventing surface defects as too little lubricant or too much or both creates surface finish defects. An adjustable base height allows for centering between dies and is the ideal solution for variable part production. Adjustability can be done either manually or electronically through a teach pendent or HMI (operator interface) Programmable Spray / Air Blow Positions are currently produced, and potential parts that will be made in the future. The markets for castings and forgings continues to increase, but not always for the simple, low tolerance parts. More than likely, larger, more complex parts, with higher standards, define the broadening markets. If spraying was critical before, proper spray application is crucial now. Improper application will have an even greater impact on these types of parts that may have very strict surface requirements, or internal porosity standards. Servo Controlled Servo control means the highest automation is being deployed to guarantee accuracy that could otherwise not be achieved. When your parts are long and narrow, are thin or thick walled, nothing provides pin point accuracy like a servo sprayer. The Servo Controlled Sprayer is controlled by a brushless, digital servo motor drive system attached directly to the gear reducer for maximum torque efficiency. Because there are no air cylinders, hydraulics, cams or motor brushes, reliability is improved. Continuous positioning accuracy is achieved by a “closed-loop” absolute encoder feedback system. The encoder is directly mounted to the motor shaft. Positioning accuracy of ±.020 inches provides constant repeatability. Horizontal or Vertical Layout The ability to design equipment around vertical, horizontal or tilt casting is necessity. The ability to A sprayer with independently programmable nozzles ensures repeatability for the highest quality control and guarantees that low temperature versus high temperature areas are treated with the correct amount of lubricant. Servo Controlled Spray allows for pinpoint accuracy at critical predetermined locations of your die. With the ability to stop and spray at multiple positions for a different pre-determined time, this will assist with preventing non-fill, solder and porosity. Air Blow-Off is used for removing excess lube, flash and slag. Blow-off is also capable of being programmed at key programmed positions at different preset times or simply sweeping the die at a desired speed. All these functions can and should be easily set up through the HMI (Operator Interface). Continued on page 54 53
