Next-Gen. Servo-Press Control

Monday, October 1, 2018
 

Aida DSF-series servo press controlAida-America, Dayton, OH, has released the next generation of its exclusive Allen-Bradley-based DSF-series servo press control for machines with capacities from 315 to 3500 tons. The control utilizes an Allen-Bradley Compact Logix programmable logic controller for press operations, diagnostics and safety on a 19-in. Allen-Bradley PC touchscreen. Features include direct access to a pdf of the press manual and infinitely programmable stroke and velocity profiles, reportedly allowing for higher productivity than mechanical presses and improved precision as compared to hydraulic presses.

The servo-press control system includes a Beckhoff servo-motor motion controller, a 500-job recipe with flash-drive loading/ unloading capability, remote diagnostics via eWon routers, 16 die-protection control channels with PNP/NPN inputs and sensors interfaced and stored in the job-recipe memory, 16 programmable-limit-switch circuits with sensors interfaced with the job-recipe memory for quick setup, and display of actual and virtual crank angles. The control’s teach function minimizes the possibility of operator-entry error, while a three-speed, CNC handwheel step-feed control provides precise setup functionality.

Available options include an integrated four-channel, strain-gauge-type, forward-and-reverse tonnage monitor with signature analysis. An automatic counterbalance control with an electrically controlled pneumatic regulator, another option, automatically sets the slide counterbalance pressure during die setup. With the automatic die-height-adjustment control option, a resolver tracks die-height position and reports it to a control module. A variable-frequency drive for the slide-adjust motor provides two adjustment speeds—high speed (for faster adjustment) and slow speed (for fine adjustment). And, slide position can be set automatically from the job-recipe memory.

The automatic single-stroke option solves timing issues when the automation equipment cannot keep up with the press. With this feature, the press automatically stops and waits for the next initiation signal from the automation equipment. Other options include continuous on-demand operation, servo-feed-control integration and servo-press/servo-transfer integration interface.
