Coil-handling equipment feeds the new servo-driven press at Bayloff, with finished parts routing to an integrated parts washer if required.
“This transfer is not a bolt-on com- ponent, but was designed to integrate with the press,” explains Brian Bayer, Bayloff co-owner and also Rich’s son. “Both the press and the transfer system use a Siemens control platforms, allowing for increased integration and flexibility.”
Big Boost for Deep Drawing Stainless Steel
To make room for the new line, Bayloff transferred welding equipment to its other local facility and also relo- cated some light-assembly operations. Crews also added a mezzanine to house electrical panels, and the line now sits snuggly in Bayloff’s main press area.
Line production includes flow work to reduce capacity issues on other presses, including stamping of high-strength stainless-steel muffler components that require complex double draws. When performing trans- fer work, the press runs at speeds to 15 strokes/min., and should increase as the company gains experience with the new technology.
With that experience, Chris sees benefits in the stainless-steel muffler- component markets.
“Stainless is difficult to draw,” he says, “and production using the servo- press line with its drawing capabilities positions us to be more aggressive in those markets.” MF
live with a Nidec Minster FX2 600-ton servo-driven press and accompanying coil line. Based on the company’s E2 HeviStamper tie-rod-frame design, the FX2 servo press features a Siemens servo motor powering the twin-end drive and using liquid-cooling tech- nology as well as a system that opti- mizes energy usage during production. As compared to air cooling, common on large servo motors, the liquid- cooled drive affords a cooler operating temperature for longer motor life and less heat transfer to the press, accord- ing to Nidec Minster officials. In addi- tion, they say, being a closed-loop sys- tem, the liquid-cooled drive results in fewer contaminates than a typical air- cooled system that is susceptible to airborne pollutants. The press also fea- tures programmable motion profiles with many profile shapes.
A large operator interface incorpo- rates many of Minster’s Production Management Control (PMC) pro- gramming, including complete inte- gration with the coil line. Especially appreciated by lead press operator Brandon Cadreau, who was chosen for this position via his diesetting experi- ence and expertise, is a hand-wheel setup mode, allowing for precise posi- tioning of the slide during job setup and die tryout. Cadreau told Metal- Forming that the handwheel allows for fine-tuning, providing for quicker
and easier setups.
Initially, Bayloff strictly used pro-
gressive dies in the press. But with a Wayne Trail through-the-window trans- fer system, integrated as the press was installed, the press has now begun doing transfer work.
“Incorporating a transfer system into a servo press is a major challenge,” says Chris. “Coordinating the press’ slide position with the position of the transfer entails different methods than with a traditional mechanical press.”
Assisting in integrating the transfer system with the press are common control platforms.
