Deep Draw Hydraulic Press System Run by Robots

In Booth A5023, Greenerd Press & Machine Company, Inc. (Nashua, NH) will showcase their range of innovative hydraulic press systems, including a unique new automated deep draw hydraulic press system that they recently designed and built: an innovative 750 ton deep draw press that is run by robots. They designed and manufactured a custom, complex double-moving platen deep draw hydraulic press, fully integrated with two 6-Axis FANUC robots that, in addition to load/unload, also prompt the press to perform the multiple operations required to produce a heavy duty high pressure cylinder tank. The horizontal four-post gib-guided press has a 750 ton cylinder main ram (adjustable down to 150 tons) with a 350 ton cushion (adjustable down to 70 tons).

The platen size is 113 in tall x 112 in deep, length is 588 in and overall machine height is 173 in with a daylight maximum open distance of 180 in. The press weighs approximately 300,000 lb and is equipped with a powerful, compact control that features simple user-friendly touch screen functions and set-up parameters. The deep draw hydraulic press has a 108 in stroke capability and a 48 in draw. Using a 350 ton cushion to clamp a blank between the main ram and the cushion platen, the main ram of 750 tons pushes the 100 lb/ 60 in blank over a punch that is attached to the stationary platen and coins the part on the top before returning. The double-moving platen design allows the press to draw the long part at one speed and tonnage, and while still moving, switch to another speed and tonnage to coin the part properly. To retrieve the newly drawn part out of the press, a FANUC robot moves in between the double platens, and when in position, instructs the press when and at what velocity to extract the part.

Greenerd’s extensive hydraulic press capabilities include standard models along with custom designed presses to meet challenging application needs. Hydraulic presses are available in a variety of styles ranging from gap frame and straight-side to die-spotting and forging presses, with product capabilities from three tons up to 40,000 tons and bed sizes exceeding 240 in (6,100 mm). Press systems are offered for fabricating in key market segments, such as automotive, aerospace, appliance and HVAC. The company has decades of in-house applications engineering experience, successfully designing innovative, safe, efficient, reliable hydraulic presses with the latest controls and automation features for a broad range of manufacturing applications.
