SCHULER AG next month will introduce a 2,000-metric ton mechanical forging press powered by servo-drive technology, which is expected to increase process efficiency and throughput by optimizing the speed during, respectively, forming, die spraying, and part transport.
A servo drive receives a command signal from a control system, then amplifies the signal and transmits an electric current to a servomotor, so that all movement is proportional to the command signal. By monitoring the signals, the drive is able to continually adjust for deviation from programmed behavior. The overall effect is greater reliability and predictability in the production sequence, with greater throughput and thus higher productivity.
For Schuler’s new MSE 2000, running at full-speed during forming allows the process to deliver maximum forming pressure with minimal strain on the die, with contact times as short as possible. This is done without negatively affecting time required for die spraying and part transport.
Schuler designed the MSE 2000 for a forging company, which will take delivery of the machine later this year to produce high-volume parts like shafts, bevel gear wheels, and similar components.
"With our newly-developed MSE 2000, a much higher number of parts can be produced in the same amount of time compared to conventional forging presses," explained Johannes Linden, Division Industry Head at the Schuler Weingarten site. "The lifetime of the die is considerably lengthened. At the same time, the energy needs of the entire machine are reduced."
Schuler ServoDirect drive units in the head of the 2,000-mt forging press make this possible. These drives control the speed with which the die approaches the part and then moves away from it.
The table ejectors of the MSE 2000 also feature an independent servo drive, and are no longer coupled with the main drive, as in older press designs. This increases the flexibility of part transport and also accelerates the production process.
Finally, thanks to the change from a longitudinal to a traverse shaft design in the head unit, the operation of the machine becomes even smoother since the two eccentric wheels rotate in opposite directions.
