Servo Presses to 2500 Tons
Officials at the Schuler Inc. (Canton, MI) booth spoke at length about its expanded range of blanking and forming servo-drive mechanical presses—available with press force from 275 to 2500 tons and constructed from standard component modules. The presses can produce full-rated work energy operating as slowly as 1 stroke/min. Modular design with standardized components means, say company officials, short delivery times and optimized spare-parts management.
Servo-drive technology allows the individual programming of slide speed and motion sequences so that stampers can optimize parameters during forming and adapt the slide curve to each specific application. The added process control improves part quality and reduces die wear compared to conventional mechanical presses.
Schuler also met with show goers to discuss its expanded press-service capabilities, with engineers and field technicians on staff to maintain hydraulic systems, mechanical presses, control systems and automation equipment for all Schuler and, now, Mueller Weingarten brands. And, the firm now provides technical service, including major upgrades and rebuilds, in an alliance with Bliss Clearing Niagara (BCN) Technical Services.

Next-Generation Leaders Vote on Best of Show
During Next Generation Leaders Day at METALFORM on April 1, members of the PMA Next Generation Leaders Division toured the show floor to vote on the best new products on display in two categories: Best New Equipment/Service, and Best New Software. Here are this year’s winners.
Best New Software: Engineering Technology Associates (ETA)
ETA, Troy, MI, earned recognition for its latest Dynaform release 5.6, which offers many new features and includes a new module called Die System Analysis (DSA). Dynaform allows a manufacturer to entirely bypass the development of soft tooling, reducing overall tryout time, lowering costs, increasing productivity and providing complete confidence in die-system design. It also allows the evaluation of alternative and unconventional designs and materials.
The DSA module offers an LS-Dyna-based finite-element-analysis (FEA) solution to analyze die-system operations including scrap shedding and removal, die structural integrity, and sheetmetal transferring and handling. ETA officials explained to METALFORM visitors that the module can predict and correct for scrap-shedding problems during the trim-die-design stage, and that trimming operations and shedding simulations can be set up in the module’s graphical interface. Also, the DSI module simulates operational loads on the die and generates FEA models of the die structure to evaluate its strength and durability.
Lastly, the software can simulate the transfer of the workpiece through the die stations and predict any interference between the work and the tooling. Stress-strain results also can be used to prevent damage during transfer, loading and unloading.

The Break-A-Beam infrared-light-beam-based palm-button press control, from Break-A-Beam Inc., Warren, MI, now is in its third generation and was introduced at Regional METALFORM in Birmingham. The infrared beam is housed in an ergonomically designed enclosure that supplies an output signal when the press operator places his hands in the enclosure and breaks the beam.
Sold as replacements to mechanical palm buttons, the units help avoid carpal-tunnel syndrome. They include self-monitoring ability to avoid false trips during power-up, and will not activate if the beam is blocked for less than 75 msec. New is a smaller profile—3 by 3 by 3 in.
Die Clamp Includes Preload Indicator
To help die setters and other responsible for setup quickly clamp dies to rolling bolsters, press beds and slides, the Hilma Div. of Carr Lane Roemheld, Ellisville, MO, introduced a hydro-mechanical clamping nut with a built-in preload indicator. To use it, the operator manually positions the clamping nut against the clamping edge, rotates the housing against the die or sub plate, then tightens one or both hex sockets until a preload indicator pin extends fully. This action pressurizes the integral hydraulic piston and converts minimum tightening torque into a high clamping force on the tool. The clamping nut comes in thee sizes, with clamping force of 13,400, 22,400 and 33,700 lb.
