Servo Press Vs Mechanical Press

The mechanical servo press has a simple driving chain without flywheel brake and clutch that are essential in a conventional mechanical press as seen in figure 1. In conventional mechanical presses the press cycles at constant speed and press loads develop slowly building power to their maximum force at bottom dead center 180 degree crank position and then they reverse direction.

The flywheel driven mechanical press still can do high volume relatively straightforward work faster and cheaper than the servo press.

Servo press vs mechanical press. Isgec started production of hydraulic presses in 1968 with technical know how from john shaw of uk 1967 to 1978 and of mechanical presses in 1985 with tech. Aida is a global leader in the design manufacture sale service and support refurbishment and modernization of metal stamping presses and metalforming automation equipment. And the hydraulic press still remains the only technology with the maximum tonnage available throughout its. Stamtecs servo presses employ siemens servo motors which replace the standard motor flywheel and clutch brake in an otherwise traditional crankshaft or link motion mechanical press. Aida servo presses and mechanical stamping presses range in capacity from 30 to 4000 tons from 1 to 1500 strokes per minute from gap frame to straightside high speed to cold forging transfer and progressive die. The promess electro mechanical assembly press emap is a fully electric programmable motion controlled ball screw press with integrated motion control and monitoring. The stroke slide motion slide position and speed are programmable to allow many different combinations that can work with a wide variety of dies part types and production speeds. Hence all the press motions such as starting stopping and velocity change are done only by the servo motor in the servo press 6. Promess offers 33 different servo presses with capacities ranging from less than an ounce to over 200000 pounds to fit any application. In comparison the servo press uses software to control press speed and position which is much more flexible. Stamtecs non servo link motion press employs link motion drive technology which decreases slide velocity by up to 40 during the working portion of the. The mechanical servo press offers much of the versatility of the hydraulic press at production speeds often approaching traditional mechanical presses. Servo driven mechanical presses wont replace their standard counterparts any time soon sources said. The mechanical servo press provides the best of both worlds as it allows manufacturers to achieve the versatility of a hydraulic press coupled with the production speeds of a traditional. Servo presses parts such as tanks cylinders and bowl shapes as well as parts that require a dwell at the bottom of the stroke including plastics are often run on hydraulic presses.
