SELF-PIERCING BLIND NUT INSERT |
摘要 |
A threaded insert (10) which has a cutting edge (18) on its external surface (12). The cutting edge (18) is configured to punch (22) a hole (22) in a workpiece (24) while leaving a slug (26) intact, still connected to the workpiece structure (24). The cutting edge (18) is configured such that no backup die need be utilized to form the hole (22) in the workpiece (24). The threaded insert (10) includes an internal threaded portion (32), and a deformable side wall (34) which is configured to deform upon installation of the threaded insert (10), to form a blind-side bulb (36) against the workpiece (24), and against the slug (26). The threaded insert (10) is configured such that an installation tool (100) can be threaded (40) into the threaded insert (10), and then the installation tool can be used to cause the threaded insert (10) to pierce through the workpiece (24). Then, the installation tool is actuated (44) to cause the deformable side wall (34) of the threaded insert (10) to plastically deform and form the blind-side bulb (36). |
