Abstract:
1. An oil-pressure swaging tool for rebuilding a connecting pipe comprising: an abutting member abutting against an oil-pressure device, a first end of the connecting pipe retained by the abutting member, a connector inserted into the connecting pipe, a first end of a first axial member passing through the abutting member and connected to a first end of the connector, and a second end of the first axial member connected to the oil-pressure device; a rebuilding member assembled to a second end of the connecting pipe, a pressure collar adjacent to a first end of the rebuilding member opposite to the connecting pipe, a first end of a second axial member passing through the rebuilding member and connected to the pressure collar, a second end of the second axial member connected to a second end of the connector; and the rebuilding member having an oblique surface at a second end thereof, the oblique surface abutting against a surface of an opening at the second end of the connecting pipe; wherein, when the oil-pressure device is working, the first axial member is pulled by the oil-pressure device; then, the connector and the second axial member move toward the abutting member via the motion of the first axial member, and the pressure collar pushes the rebuilding member toward the second end of the connecting pipe via the motion of the second axial member; thereafter, the oblique surface of the rebuilding member presses the surface of the opening at the second end of the connecting pipe until that is rebuilt and the oil-pressure device stops operating.
