The reliable connection of their ends is paramount, directly impacting equipment and personnel safety. Sleeving technology is currently one of the most widely used methods for connecting wire rope ends. Wire rope sleeving machines use a cold-working process to press metal sleeves to permanently connect the wire ropes. However, traditional wire rope sleeving machines suffer from bulky hydraulic cylinders, high overall casting costs, and high maintenance costs. Therefore, a new type of wire rope sleeving machine is urgently needed in this field. Utility Model Content

The base box 1 and the hydraulic system 14 are fixed on the base 15, the lower box 2 is fixed on the base box 1, the lower ends of the four guide columns 4 are fixed to the four symmetrical corners of the lower box 2 by nuts 17, the upper ends of the guide columns 4 pass through the middle box 12 and the upper box 6 in sequence, and are fixed to the upper box 6 by nuts 17. The upper mold 13 and the lower mold 16 are respectively installed at the lower end of the middle box 12 and the upper end of the lower box 2. The hydraulic system 14 is connected to the oil inlet of the hydraulic cylinder 7 through the oil outlet pipe 8, and the oil outlet of the hydraulic cylinder 7 is connected to the hydraulic system 14 through the oil return pipe 20. The hydraulic system 14, the oil outlet pipe 8, the hydraulic cylinder 7, and the oil return pipe 20 form a circulating oil circuit. The upper end of the drive component is connected to the lower end of the hydraulic cylinder 7, and the lower end of the drive component is connected to the upper end of the middle box 12. The hydraulic cylinder 7 pushes the drive component, causing the middle box 12 to slide on the guide column 5.

[0021] The drive components include: two lower left connecting rods 3, two upper left connecting rods 18, two upper right connecting rods 19, two lower right connecting rods 11, a push rod 9, a left connecting rod 5, and a right connecting rod 10. The upper end of the push rod 9 is fixed to the lower end of the hydraulic cylinder 7. The lower end of the push rod 9 is hinged to one end of the left connecting rod 5 and one end of the right connecting rod 10. The other end of the left connecting rod 5 is hinged to one end of the two upper left connecting rods 18 and one end of the two lower left connecting rods 3. The push rod 9 is located at the front of the other end of the left connecting rod 5. Both ends are sequentially equipped with one end of the lower left connecting rod 3 and one end of the upper left connecting rod 18. The pin 21 passes through one end of the upper left connecting rod 18, one end of the lower left connecting rod 3, the other end of the left connecting rod 5, one end of the lower left connecting rod 3, and one end of the upper left connecting rod 18 from front to back. The other ends of the two lower left connecting rods 3 are hinged and fixed to the upper end of the middle box 12 by the pin 21, and the other ends of the two upper left connecting rods 18 are hinged and fixed to the lower end of the upper box 6 by the pin 21.

[0022] At the front and rear ends of the other end of the right connecting rod 10, one end of the lower right connecting rod 11 and one end of the upper right connecting rod 19 are installed in sequence. The pin 21 passes through the upper right connecting rod 19, the lower right connecting rod 11, the other end of the right connecting rod 10, the lower right connecting rod 11, and the upper right connecting rod 19 in sequence from front to back.

[0023] The bottom box 1, upper box 6, lower box 2 and middle box 12 are made of rectangular plates welded together.

[0024] When the hydraulic system 14 is pressurized, the hydraulic cylinder 7 pushes the push rod 9 downward, and the left connecting rod 5 and the right connecting rod 10 open, so that the upper left connecting rod 18 and the lower left connecting rod 3, the upper right connecting rod 19 and the lower right connecting rod 11 are nearly perpendicular and collinear. The upper left connecting rod 18 and the lower left connecting rod 3, the upper right connecting rod 19 and the lower right connecting rod 11 together push the middle box 12 to move downward along the four guide pillars 4, so that the upper mold 13 installed at the lower end of the middle box 12 approaches the lower mold 16, realizing the action of the wire rope pressing sleeve, that is, mold closing.

[0025] Conversely, when the hydraulic system 14 is depressurized, the hydraulic cylinder 7 causes the push rod 9 to move upward, and the left connecting rod 5 and the right connecting rod 10 close, so that the upper left connecting rod 18 and the lower left connecting rod 3, the upper right connecting rod 19 and the lower right connecting rod 11 form an angle. The upper left connecting rod 18 and the lower left connecting rod 3, the upper right connecting rod 19 and the lower right connecting rod 11 together drive the middle box 12 to move upward along the four guide pillars, so that the upper mold 13 installed at the lower end of the middle box 12 moves away from the lower mold 16, realizing the action of decompressing the wire rope, that is, opening the mold.
