Abstract

The invention relates to mechanical engineering and can be used to associate information tags and reusable locking elements. The invention makes it possible to securely connect the ends of the rope by tightening its ends through a flattened tube with the formation of a loop. Alternatively, the connection can be placed on a support. The rope pulled into the tube is tensioned with calibrated fixtures until the free loops are removed with a force of no more than 45% of the break. The thickness of the splice tube is not more than three thicknesses of its wall, s. 2 sec. the item of f-ly, 8 ill.

Description

The invention relates to mechanical engineering and can be used for tying information tags and reusable locking elements.

The purpose of the invention is to increase the reliability ’and durability of the connections.

Figure 1-6 shows the sequence of methods for implementing the method; in FIG. 7 and 8 are distinctive sketches of an embodiment of the method.

The method of connecting and attaching the ends of a small-diameter metal rope with a metal tube (its variants) consists in pre-flattening the tube 1 with a mandrel on a press (Fig. 1) to create a shape that allows three diameters of the rope 2 to be placed in a row. The end 3 of the rope 2 is introduced into tube 1 (FIG. 2) and, forming a loop 4 (FIG. 3), lead back, and the end 5 of the same rope (FIG. 4) is threaded into loop 4 and inserted into the tube from the opposite side (FIG. 5).

In a variant of the method, the tube 1 is preliminarily flattened to create a shape that allows three rope diameters to be placed in a row. The end 6 of the rope 7 is captured by a loop. 8 support 9 and bring it back through the tube 1, and the free end 6 is introduced into the tube from the side of the loop 8.

The rope (2 or 7) is pulled along the arrow A, B or C, with a calibrated device until free loops are removed with a force of not more than 45% of the breaking one, and the tube 1 is flattened at the ends of the rope with the help of calibrated pliers to a thickness of 10-15% less than three wall thicknesses, ensuring reliable adhesion of the tube to the rope without its destruction. The ends 3, 5, 6 of ropes 2 or 7 (FIGS. 5 and 8) should not protrude from the tube. The tube material should be more viscous than the material of the wire rope. The tube wall thickness is equal to the lumen width of the pre-flattened tube (rope diameter) to ensure that the rope bends along a radius equal to the rope diameter and prevents destructive stretch marks and wire fractures, and the wall bend radius is equal to its thickness. The length of the tube is 10-20 thicknesses of its wall (10-20 widths of the clearance of the pre-flattened tube or 10-20 diameters of the rope) to ensure reliable retention of the ends of the rope and together with 5 the wall thickness of strength equal to or greater than the strength of the rope. The internal cross-sectional area of the pre-flattened tube must contain the rope diameter three times and the edges of the tube are rounded.

The invention relates to mechanical engineering and can be used to associate information tags and reusable locking elements. The purpose of the invention is to increase the reliability and durability of compounds. Figures 1-6 illustrate a sequence of techniques for carrying out the method; in fig. 7 and 8 are distinctive sketches of an embodiment of the method. The method of connecting and fixing the ends of a metal rope of small diameter with a metal tube (its variants) is that the mandrel 1 on the press presses tube 1 (fig. 1) to create a mold that allows you to place The three diameters of the rope 2, the end 3 of the rope 2 are inserted into the tube 1 (Fig. 2) and, forming a loop 4 (Fig. 3), are retracted, and the end 5 of the same rope (Fig. 4) is threaded into the loop 4 and introduced into the tube from the opposite side (Fig. 5). In a variation of the method, tube 1 is pre-flattened to create a mold that allows three diameters of the rope to be placed in a row. End 6 of rope 7 lock loop. 8, the support 9 and the cable trough it back through the tube 1, and the free end 6 is inserted into the tube from the side of the loop 8. The rope (2 or 7) is pulled along the arrow A, B or B using a tared device until the free loop is eliminated with a force of no more than 45% of the breaking and flatten the tube 1 at the ends of the rope finally using tarirov pliers to a thickness of 10-15% less than three wall thicknesses, ensuring reliable adhesion of the tube with the rope without destroying it. The ends 3, 5, 6 of the ropes 2 or 7 (figure 5 and 8) from the tube should not protrude. The tube material must be more viscous than the wire wire material. The wall thickness of the tube is equal to the width. The lumen is not pre-expanded with a valuable tube (rope diameter) for wrapping liver bends of a rope along a radius equal to the diameter of the rope and preventing destructive strains and fractures of wires, and the bending radius of the walls is equal to its thickness. The length of the tube is 10-20 its wall thickness (10-20 width 12 6 of the lumen of the previously spun tube or 10-20 rope diameters) to ensure reliable holding of the ends of the rope and, together with the wall thickness, equal or greater strength of the rope. The inner cross-sectional area of the pre-expanded tube must contain the diameter of the rope three times and the edges of the tube are rounded. Claim 1. The method of connecting and fixing the ends of a metal rope of small diameter with a metal tube, which consists in pre-flattening the tube, passing the end of the rope through the tube, forming a loop and inserting the free end back into the tube, while the free end does not protrude beyond the end of the tube, due to the fact that, in order to increase reliability, the second end of the rope is threaded through the formed loop and inserted into the opposite end of the loop of the tube, and the tube is flattened out finally, while the tube has a wall of thickness The width of the gap is flat in the flattened state, the length of the gap is chosen from the calculation of the placement of three ropes in a row, and the bending radius of the tube wall is equal to the wall thickness. 2. The method of connecting and fixing the ends of a metal rope of small diameter with a metal tube, preferably with a support, which consists in the fact that the tube is pre-flattened, the end of the rope is inserted into the tube, a loop is formed, and the free end is again inserted inside the tube. the end does not protrude beyond the end of the tube, characterized in that at the time of looping the end of the rope captures the support element, said end of the rope is inserted into the tube from the loop side, and the tube is flattened finally, while the tube s an wall thickness equal to the width of the lumen in a collapsed state, length of the lumen three times prevshaet width and the wall of the tube bend radius is equal to the wall thickness.
