Abstract
A method of securing a termination element to an end portion of a wire rope, the termination element having an elongated, ductile tubular sleeve portion, including the steps of positioning the end portion of a wire rope within the tubular sleeve portion, positioning the sleeve portion between co-acting dies, the dies having an opening that is non-circular in cross-section, closing the dies a first time to deform the sleeve portion about the wire rope and into a non-circular external cross-section shape opening dies rotating the sleeve portion less than 180° closing the dies a second time to form the sleeve portion into a final external non-circular shape and opening the dies to remove the termination element.
Claims12
A method of securing a termination element to a terminal end of a wire rope, the termination element having an elongated, ductile tubular sleeve portion and an integral socket portion, comprising:
- positioning the terminal end portion of the wire rope within the tubular sleeve portion of the termination element, said sleeve portion having a cylindrical external surface;
- positioning said sleeve portion of said termination element between co-acting dies, said dies having abuttable lands and having an opening that is quasi-polygonal in cross-section with n sides, where n is an even number greater than four, said co-acting dies having at least one of said sides forming a reservoir area wherein a pair of said reservoir areas are on oppositely facing sides said reservoirs accommodating flashing from said sleeve portion;
- fully closing said dies upon said sleeve portion to form a preformed quasi-polygonal swage opening said dies;
- rotating said sleeve portion with respect to said dies an amount V, where V is equal to 360° /n;
- fully closing said co-acting dies whereby said lands abut to form a final quasi-polygonal opening of predetermined after swage dimension, said reservoir again accommodating flashing from the sleeve;
- and
- opening said dies to remove said swaged termination element, said swaged termination element having a quasi-polygonal external surface.
A method of securing a termination element to a terminal end of a wire rope, the termination element having an elongated, ductile tubular sleeve portion and an integral socket portion, comprising:
- positioning the terminal end portion of the wire rope within the tubular sleeve portion of the termination element, said sleeve portion having a cylindrical external surface;
- positioning said sleeve portion of said termination element between co-acting dies, said dies having abuttable lands, said dies having an opening that is quasi-polygonal in cross-section;
- fully closing said co-acting dies upon said sleeve portion whereby said lands abut to form a predetermined quasi-polygonal cross-sectional swage;
- opening said dies;
- rotating said sleeve portion with respect to said dies an amount less than 180°;
- fully closing said co-acting dies whereby said lands abut to form a final quasi-polygonal opening of predetermined after swage dimensions;
- and
- opening said dies to remove said swaged termination element.
