Abstract
A hand-held portable crimping tool for crimping fittings to hose assemblies, is manually operable, has removable snap-in dies, and yoke that is hydraulically powered. Operation of the tool causes the snap-in dies to crimp the fitting, wherein a linear force is transformed into a non-linear force applied by the snap-in dies to the fitting.
Claims13
A hand-held portable crimping tool for securing a fitting to a hose comprising:
- a hydraulic body having a crimping piston;
- a yoke comprising a top yoke and a bottom yoke, wherein the bottom yoke is coupled to the hydraulic body and the top yoke is coupled to the bottom yoke;
- a top die locator in communication with the top yoke;
- a bottom die locator in communication with the bottom yoke;
- crimping-dies for crimping the hose, said crimping-dies coupled to the bottom die locator and the top die locator;
- and,
- a guide foot and a corresponding guide hole for a particular crimping-die, the guide foot is comprised of a resilient material, wherein movement of the guide foot into the corresponding guide hole changes the relative position the particular crimping die when a crimping force is applied by the crimping-dies to the fitting;
- wherein application of a linear crimping force applied by the crimping piston is transformed to a controlled non-linear crimping force as applied by the crimping-dies to the fitting.
