Abstract:
A crimping tool for a metal hub plate comprising:a plunger assembly having a central axis and being moveable along said central axis, said plunger assembly including: a plurality of crimping jaws positioned radially with respect to said central axis, said crimping jaws being subjected to a force such that said crimping jaws project from an end of said plunger assembly; and a plurality of surfaces oriented at an acute angle with respect to said central axis, each of said crimping jaws being slidable on a respective one of said surfaces such that when one of said crimping jaws slides on said respective one of said surfaces, the motion of said crimping jaw relative to the surface has a first component parallel to said axis and a second component perpendicular to said axis said surfaces being oriented such that said crimping jaws move towards said central axis to crimp said metal hub plate when said crimping jaws are moved in a direction opposite to said force; and a die for retaining said metal hub plate and positioned in said tool that said crimping jaws contact said die to move said crimping jaws towards said central axis when said plunger assembly is displaced a distance from a retracted position in the direction of said force along said axis.
