Embodiment 1
[0031] Embodiment 1: as Figure 1-15 As shown, a full-tension aluminum-embedded crimping structure of aluminum-steel-reinforced wire includes an aluminum splicing tube 1, a steel splicing tube 2, a steel core splicing aluminum tube 3, an inner embedded aluminum tube 4, and an outer embedded aluminum tube 5. and the qualitative ring 6 of the wire, the steel core connecting aluminum tube 3 is sleeved on the two butted steel strands 7, the steel connecting tube sleeve 2 is connected to the outside of the steel core connecting aluminum tube 3, and the steel connecting tube sleeve 2 is crimped to make the steel The core is connected with the embedded aluminum tube 3 to closely fit the steel strand 3 to form a steel strand crimping joint; the inner layer aluminum tube 4 is placed on the steel strand 7 and the inner aluminum strand layer 8 that are connected to each end of the steel core aluminum strand Between the butt-connected steel-cored aluminum stranded wires at each end is con...
Embodiment 2
[0035] Embodiment 2: A full-tension aluminum-embedded crimping method for aluminum-steel-reinforced wires: the method includes the following steps:
[0036] 1) Cut off the aluminum strands of the steel-reinforced aluminum strands at both ends of the butt joint, and the length of the cut-off section at each end = the length of the steel connecting pipe / 2+20mm;
[0037] 2) Pull the two joints of the steel-reinforced aluminum stranded wire to 10 meters, put one end of the steel-reinforced aluminum stranded wire into the aluminum connecting pipe, and move the aluminum connecting pipe to a position that does not affect the next process;
[0038] 3) Insert one end of the steel-cored aluminum stranded wire into the outer embedded aluminum tube, and the large inner diameter end of the outer embedded aluminum tube points to the joint, and move the outer embedded aluminum tube to a position that does not affect the next process;
[0039] 4) Insert the wire setting ring into the butted s...
