Stretch Forming Presses
Stretch Forming Presses
Process accuracy, consistency, and repeatability using Stretch Forming
Macrodyne Stretch Forming Presses are available in a variety of configurations to form Sheet Metal, Extrusions, and Brake-Formed Profile Parts by using the Stretch Forming method. The Sheet Press is typically used to form large sheets, while the Swing Arm (V-Press) is used for Extrusions and Break Formed parts. Each can be equipped to form any of the three types of parts. These forming methods are used worldwide across many industries. Most notable in the Aerospace industry. We understand the aerospace industry’s requirements, and we have consistently delivered solutions to them that are reliable, repeatable, and precise. Macrodyne is committed to supplying quality hydraulic press solutions that exceed the needs of your industry.
Sheet Stretch Forming Press for Fuselage Skin Panels
Designed to grip each end of the sheet stock material. Then it applies the required tension force to stretch the material beyond its yield point and into its plastic region. It maintains the sheet tension while the sheet is wrapped over the Forming Die. This process creates quality parts with no wrinkles, even stress distribution, and minimum spring back.
The machine’s structural components are designed using FEA, stress relieved, and accurately machined to provide rigid support of the forming process.
The Loading, Unloading, and Forming motions of the press are controlled by a PLC-based CNC control system. An added feature of the control system is the ability to create part forming programs. The programs provides consistent and repeatable forming cycles for quality parts production. The programs can be saved and reloaded for future use.
Control Features
PLC-based Control System with HMI for CNC functional axis control for process accuracy, consistency, and repeatability of more than 30 axes of motion. Forming type available based on press type:
- DrapeStretch DrawTransverse FormingLongitudinal Forming
- Bullnosing, including Leading Edge FormingStretch Wrap – utilizes Tangency tracking deviceTransverse/Longitudinal – w/ Rotating Die Table
Note: Special part, die, and press forming program development software package available.
