The video demonstrates Oilgear’s ability to forge at very high stroking rates to within a +/-1.0mm.
The example video shows a 6000T Open Die Push-Down press, having a weight of parts of 250T and a flow rate of 7,200 l/min forging @ 150 strokes per minute with an apple between the dies to illustrate the precision and repeatability of the control.
The high performance fast forging is realized by use of our dual-forge header system that allows flow from the A-Header to be constantly pumped to the main cylinder(s) even while the press is being returned, resulting in a much faster response time when switching from Stop Forge to Forge.
Also, because of the fact that the pump flow is always flowing in the same direction and is only switching directions between the main cylinder(s) and the fast forge valve, no shocks are experienced.
