Abstract
A lock nut having a plurality of sides having a radius crimp which is consistent with the radius of the threaded bore in the lock nut. Preferably, the lock nut is crimped using a three sided die, each die having a radius crimp with relief angles. The relief angles are provided at a desired angle to result in the desired amount of contact area between the lock nut and the die. The device includes a housing, and the housing includes at one end a threaded bore which is configured to mount on a ram. An opposite end of the housing provides a tapered die section in which the three sided die is disposed. The three sided die is engaged with a locking die base which is movable within the housing.
Claims31
A crimped lock nut comprising a plurality of sides and a central, threaded bore, wherein a plurality of the sides are crimped such that there is provided at least one concave crimp radius.
A device for crimping a lock nut having a central, threaded bore, wherein a plurality of the sides are crimped such that there is provided at least one concave crimp radius, said device comprising:
- a housing having an opening;
- and a multiple-sided crimp die disposed in the opening of the housing, wherein each of the sides of the crimp die is configured to crimp a corresponding side of the lock nut with at least one concave crimp radius.
