Servomechanicals Shine
To get the most bang for the buck, and to draw the most from servome- chanical presses’ formidable capabil- ities, metal formers would do well to optimize tooling, in-die processes and automation for this technology, accord- ing to Ellard.
To help do that, Stamtec organized its Servo Press Tooling Seminar, a Sep- tember 2019 event held at the compa- ny’s new Servo Press Technology Center and Die Try-Out Facility in Manchester, TN. Targeting those wondering how servo press technology can specifically benefit their own press productivity, improve parts quality and boost prof- itability, the seminar provided onsite consultation with tool and die shops, and demonstrated several servome- chanical presses under power. These included a 660-ton straightside press as well as C-frame presses ranging from 121 to 220 tons.
“The bottleneck for fully realizing servo press potential lies squarely with the parts manufacturers and tool
builders learning to design and build tools for servo presses,” Ellard told Met- alForming while promoting the semi- nar and urging stampers to fully benefit from servomechanical press technol- ogy. “We are seeing more creative die designs because the technology affords virtually unlimited stroke and motion profiles. The evolution of dies will con- tinue, as will the level of sophistication when it comes to integrating controls, processes and automation.”
Controls specifically designed for Stamtec’s servomechanical presses fea- ture user-friendly interfaces, and given the stroke and slide-movement flexi- bility, enable users to perform a variety of jobs—drawing, restrike, warm form- ing, etc.—in one press. Stamtec can custom-supply unique profiles, while customized motion curves allow as many as 20 various segments in a cycle curve, defined by segment position, speed and pause-duration parameters.
The controls can incorporate automation and feed applications, and
enable automatic slide adjustment and die-height auto-correction. Other fea- tures include 100-job storage, pulse generator wheel for die tryout, ethernet link and incorporation of task-assign- ment software.
Stamtec showcased its servome- chanical press and control offerings at FABTECH via a variety of machines configured to run actual production of small deep-drawn parts. Machines displayed included two 110-ton servo presses along with other mechanical link-motion and traditional mechanical presses. The company also displayed a feed line consisting of a combination uncoiler/straightener paired with a servo feeder.
