When using cold-forming processes to assemble parts, several factors, including part design, material, and orientation, may cause workpieces to react unexpectedly. As a result, the components may require clamping before and during forming. If it is possible, part fixtures can incorporate this clamping requirement. When this is not feasible, Orbitform offers pressure pads that are part of the forming head to apply a clamp-load before and during forming. Manufacturers may be familiar with Orbitform’s Orbital and Radial Pressure Pads. However, we also offer an industry-exclusive Thru-Spindle Pressure Pad for our Static and Articulating Roller Forming processes.
What is Roller Forming?
Roller Forming is a non-impact process that uses two or more rollers to apply 360 degrees of symmetrical force around a cylindrical part. This process often replaces press crimping, which can introduce cracking into the material and result in inconsistent forms. Orbitform has been offering Roller Forming since 2005 with two different applications of the process - Static and Articulating. Utilizing these processes, manufacturers can form a smooth lip around a part, add a groove, flare a tubular piece outward, or form an undercut. Like other assemblies, it can be necessary to compress these components before and during forming, requiring our Thru-Spindle Pressure Pad.
What is the Thru-Spindle Pressure Pad?
Unlike our Orbital and Radial Pressure Pads - which attach to the outside of the orbital or radial head - The Thru-Spindle Pressure Pad is installed through the center of the powerhead spindle, directly in line with the forming process. The powerhead also includes an off-set motor drive to allow for clearance of the pressure pad. Installing the pressure pad through the spindle ensures that clamping of the components can occur without interfering with the rollers. Examples of applications requiring clamping include retaining internal components or when specific compression forces are needed, such as when creating a seal.
Utilizing the Thru-Spindle Pressure Pad with our Roller Forming Processes is another way manufacturers partnering with Orbitform ensure their finished assembly meets their functional requirements. With nearly 40 years of experience in the industry, our Assembly Experts can help identify the correct assembly process and any necessary machine options, like a pressure pad, to ensure success.
