Problems solved by technology

The usual practice is to tie a knot at the end of the fiber rope, but obviously the problem of uneven stress caused by knotting is a fatal defect. If the stress of the fiber rope cannot be made uniform, as long as one of the fiber filaments breaks, it will cause other problems. fiber breakage

Embodiment Construction

[0011] A method for forming the end of a fiber rope, including a fiber rope and a joint, spreading out each strand at one end of the fiber rope, taking about 1 / 3, folding and inserting in half, and then pre-tensioning to make the inserting part uniform, so that the end of the cable body increase in diameter;

[0012] The connection end of the joint has a tapered hole, and the small-diameter end of the tapered hole is selected for the joint to be 2 to 3 mm larger than the diameter of the end of the thickened fiber cable, and the length of the tapered hole is 3 times the diameter of the thickened fiber cable end. -5 times, the taper is 12-15 degrees, and then, the end of the thickened fiber cable is penetrated from the small-diameter end of the joint, and then the end of the fiber cable is scattered into a cone shape, so that the fibers are evenly dispersed inside the joint In the casting cup, and keep the fiber cable coaxial with the taper hole,

[0013] Then the fiber strands...

Abstract

The invention discloses an end molding method for fiber ropes. The fiber ropes comprises fiber rope bodies and joints. The end molding method comprising the following steps of: loosening each strand of one end of every fiber rope, folding about 1 / 3 of the fiber ropes, performing inserted weaving, and pre-stretching to cause the inserted and weaved part to be uniform and the diameters of the end heads of the rope bodies to be increased. Compared with the prior art, the end molding method for the fiber ropes solves the problem of intensity casting of soft ropes, and particularly has an obvious effect on high-intensity fiber ropes, such as aramid fiber, ultra-high molecular-weight polyethylene fiber ropes and PBO (Poly-p-phenylenebenzobisthiazole) fiber ropes.

Description

technical field [0001] The invention relates to a method for forming a fiber rope end, which belongs to the technical field of rigging manufacturing. Background technique [0002] The durability and tensile strength of the fiber rope are a key factor affecting the life of the fiber rope. In order to improve the endurance requirements of the fiber rope, the end of the fiber rope is subjected to various stresses, so the service life of the end of the fiber rope directly affects the service life of the entire fiber rope. The usual practice is to tie a knot at the end of the fiber rope, but obviously the problem of uneven stress caused by knotting is a fatal defect. If the stress of the fiber rope cannot be made uniform, as long as one of the fiber filaments breaks, it will cause other problems. Fiber breakage. Therefore, based on the above content, it is necessary to design a fiber rope with uniform stress. Contents of the invention [0003] In order to make joint casting ...
