Press riveting is a permanent assembly process that applies a downward force to form/displace material. The head package can be pneumatic, mechanical, hydraulic, servo, or hydro-pneumatic driven. This process is used often when the functional requirement of the joint demands maximum hole fill or workpiece-to-part-surface contact.
The press head applies downward force to form/displace the material, permanently securing the parts together. This process maximizes hole fill within the joint. Press Forming: Special driver and anvil tooling are used to form the material to a specified finished form geometry. Force and distance monitoring can be used to validate success of the process.
Press Bushing Flare and Flatten
A bushing is placed into a hole and is flared at a 45-degree angle then flattened to achieve a 90-degree angle bend to maximize surface contact.
