Custom Hydraulic Stamping Press
who explained the workings of this technology.
“The triple-action press consists of a punch or forming tool on the main draw ram, a clamp ram in the middle, and a knockout cylinder and/or bed cushion on the bottom,” he says. “The clamp ram contacts the blank and is engaged throughout the forming process to control material flow, reduc- ing the risk of wrinkles or tears within
the part. By giving operators the ability control material flow, they will achieve greater success in forming parts.”
The clamp ram also features indi- vidual tonnage control on each cylinder. “If operators want one corner of a sheet to flow inward more rapidly, they can reduce tonnage on that cylinder, while increasing tonnage on the other side to provide more holding force,”
says Dixon.

Weldmac’s new press joins this 5000-psi sheet-hydroforming press, installed in early 2016, which doesn’t require mated tooling or secondary finishing, yet yields complex, net-shaped parts.
Unique to all Beckwood triple- action presses is the ability of the lower ram to serve either as a knockout for part ejection or as a cushion, depend- ing on tooling requirements. “Propor- tional control valves regulate the bed cushion, enabling dynamic control through four different travel zones,” Dixon explains. “Through the press’ HMI and recipe settings, the operator can specify a desired bed cushion force at any position within each zone.”
Handles Parts Large and Small
In addition to large-part capability, Beckwood designed the press with added versatility to handle smaller parts on jobs off-loaded from some of Weldmac’s older presses. The main ram offers capacity from 80 to 800 tons, with the clamp-ram bolster providing 10 to 300-ton capacity.
The new press will help Weldmac handle an uptick in exhaust compo- nents produced for commercial sta- tionary turbine engines as well as its thriving aerospace-supply business. It also brings more to the table.
“We excel at building complex com- ponents and assemblies,” says Rugg, “and that work continues to increase. We’ve added customers that usually come to us with one problematic part or assembly, and that leads to more business. When we do a good job, a new customer looks to give us more things to do. New press capacity and capability helps us handle that.” MF
