|Type of Press||High Temperature Hot Forming Press|
|Special Features||High-Temperature Heated Platens |
Automatic Insulated Doors
Active Leveling Control
|Challenge||Provide even heat distribution across the platen.|
|Solution||Each heated platen features nine temperature control zones for ultimate temperature uniformity, while the press’ insulated door panels maximize heat efficiency by isolating the work area during forming.|
|Challenge||Minimize the effects of off-center loading.|
|Solution||Beckwood’s proprietary Active Leveling Control System uses a closed-loop control to monitor all four corners of the press ram, maintaining a 0.002 in. tolerance corner to corner. With this technology, the press is able to intelligently, automatically maintain precise bed-to-ram parallelism.|
|Results||Ducommun is able to run nearly 60% of its parts on the Beckwood press. Part quality and repeatability have been excellent, but the biggest gain is that they now have the available time and capacity to make more of the parts their customers need.|
Ducommun AeroStructures engineers and manufactures contoured aero structure components for commercial aircraft, regional and business jet aircraft, military aircraft, helicopters, and space launch vehicles. They employ many unique processes for manufacturing molded composite parts and strong metal alloys including titanium.
Beckwood Press helped analyze Ducommun’s need and manufactured a 75-ton hot forming press capable of temperatures up to 1600°F. The heated platens used in this press provide multiple zones of temperature control for ultimate temperature uniformity – which is critical to Ducommun’s titanium forming operation. Additionally, the press is outfitted with an automatic, insulated door system which helps maximize heat efficiency by isolating the work area during forming.
The press also features Beckwood’s proprietary Active Leveling Control System (ALC) to minimize the effects of off-center loading, allowing it to intelligently and automatically maintain precise bed-to-ram parallelism. The ALC system uses a closed-loop control to monitor all four corners of the press ram, maintaining a 0.002” tolerance corner to corner. “It’s something we hadn’t used before so we were excited about having the technology,” says Joshua Frank, Manufacturing Engineer for Ducommun. “The feature gives us an advantage if we are dealing with part geometry that causes the load to be slightly off-center.”
Variable ram speed control, PressLink communications for remote troubleshooting and a programmable control system with recipe functionality all add to the machine’s flexibility, allowing Ducommun to more efficiently form their current and future family of parts.
This hydraulic hot forming press is able to run nearly 60% of Ducommun’s dies, the press also has the flexibility to run larger jobs that typically require its larger press while still being able to handle small- and medium-sized work. “Part quality and repeatability have been excellent so far,” says Frank. “The biggest gain of course is that by adding this press we now have the available time and capacity to make the parts our customers need.”
