Latest Patents

Two of Bardelli’s listed patent descriptions concern power installation tools for helical coil inserts.

One design uses a tubular body with a bore and a coaxial mandrel rotated by a motor. An air cylinder applies axial force to the mandrel. A recess in the tubular body holds an insert in alignment with the bore, while an opening provides access to the recess. The body can move to bring the insert into engagement with the mandrel, which installs it to a selected depth. The mandrel also slides axially to remove the insert’s tang after installation.

A related design adds a punch positioned inside the mandrel. In this version, the motor rotates the mandrel, while an air cylinder applies axial force to the punch. The mandrel moves from a retracted position to engage and install the insert at a selected depth. The punch then slides through the mandrel to remove the tang.
