Background technique

The crimping of the ground wire is an important link in the connection of power transmission and transformation wires, and the quality of the process is directly related to the safe operation of the power grid. For large-section wires, the crimping length and the required crimping force are relatively large. After the steel cores of the two wires are crimped and inserted into the middle of the connecting tube, the connecting tubes need to be crimped. Crimping the ground next to one die, and moving and crimping 8-16 dies, which lasted about 20-30 minutes. After crimping a mold at multiple crimping positions, the wire and crimping tube need to be lifted and placed on the next mold position for crimping, and the entire connecting tube is crimped in turn. Every time a die is crimped, due to the influence of the center of gravity of the wires on both sides, the angle of entry into the die changes, which will affect the straightness of the crimping of the connecting tube, resulting in poor results in the industry and difficult to correct.
