Stamping Simplified Via Controls
through a VPN connection allows Helm access to the press control to support or address any customer-required changes to the control package. The PLC offers 100-job-recipe storage, aiding Omni Man- ufacturing immensely as it performs fre- quent die changes.
Omni Manufacturing’s press-control quest arose out of its heavy use of in-die sensing and other press automation, such as the aforementioned transfer systems, according to Bob Prater, vice president and tool room manager, and Craig Rupert, systems coordinator.
Benefits Evolving Sensor Program
Omni Manufacturing has employed
sensors in press operations for 30-plus
years, beginning with short-feed and
part-out sensors, according to Prater and Rupert.
cams have returned, and, in transfer applications, that we are monitoring the transfer position. The user-friendliness of the press control has simplified the process of incorpo- rating sensors to our die/press monitoring package.”
Says Rupert: “Helm supplied basic control packages that we could customize to our needs. Up front we provided a
“These were pretty simple applications due to the simple press-control packages we had at the time,” says Prater. “We’ve evolved to where we not only check for short-feed and part-out conditions, we are also checking to ensure that parts are in the correct position, that trim and form
Presses and tooling at Omni Manufacturing are fully sensored. Inside of this press and in the tooling, nearly 50 sensors monitor the transfer and trimming of cylindrical auto- motive-suspension parts.
