solutions for de-riveting assemblies

Manufacturers turn to Orbitform for assembly solutions, but what can be done when disassembling permanent fasteners is required?  De-riveting is a common technique used to save money and re-work parts.  When seeking a solution for de-riveting assemblies, many manufacturers turn to Orbitform.

Orbitform has worked with manufacturers in many industries to develop de-riveting systems.  Typical applications include brakes especially for trucks, automotive components and reusable sports equipment.  De-riveting solutions are sought out when one of the components of an assembly can be replaced in the aftermarket, or when one or more of the components are of a high value and require rework.  The proper path of de-riveting is determined by whether a solid or semi-tubular rivet is used.

Semi-Tubular De-Riveting

When de-riveting semi-tubular rivets, a straight push applies force to the formed head of the rivet. This can be accomplished by either an impact or press machine.  As the driver pushes and overcomes the retention force, the formed head uncurls, allowing it to be pushed back through the hole.

Solid De-Riveting

Solid rivets present a larger challenge when de-riveting.  The manufactured head must be ground or milled off prior to pushing the rivet back through the hole.  When removing solid rivets, the material of the component surrounding the hole must be considered.  If the material is softer than the rivet, there is a chance it will be damaged.  If the hardness is equal to or harder than the rivet the risk of damage is lower, as it will maintain its shape while the softer rivet is pushed back through.  How the rivet was initially formed also plays a role in the de-riveting process.  The larger the shank swell created in the forming process, the higher the risk of damage to the surrounding component.
