Wire crimping device and wire crimping method

Abstract

The invention provides a wire crimping device and a wire crimping method. The device comprises a supporting main body, a mold cover, a mold, an eddy current heating bent plate, a hydraulic cylinder and a hanging beam, the hydraulic cylinder on the supporting main body controls the mold to be closed and separated so as to realize crimping of a to-be-crimped wire, the eddy current heating bent plate heats the to-be-crimped wire, and the to-be-crimped wire is heated by the hanging beam so as to make the heated wire convenient to crimp, and the performance requirement of a hydraulic machine can be reduced; and the hydraulic mode is simple, the crimping quality is better, the to-be-crimped wire is fixed through the threaded connecting rod and the locking buckle which are connected through the hanging beam, the crimping error caused by position dislocation of the to-be-crimped wire and the mold is reduced, and the crimping quality is improved.

Description

technical field [0001] The invention relates to the technical field of construction of important cross-over lines, in particular to a wire crimping device and a crimping method. Background technique [0002] Important crossings are overhead transmission lines that cross sections such as high-speed railways, expressways, first-class highways, first- and second-level navigable rivers, and important overhead transmission lines. It may cause casualties or major economic losses, so the iron towers, fittings, insulators and wires of important crossing lines should be strengthened; the wires and insulators are connected by tension clamps at both ends of the crossing section. The connection between the wire and the wire is connected by the connecting fitting. When the strain clamp and the connecting fitting are damaged, it will cause a line disconnection accident. Therefore, the safety of the strain clamp and the connecting fitting has an important impact on the entire circuit. [...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, at present, a hydraulic press is mainly used to crimp the wire clip and the wire at room temperature to cause plastic deformation to achieve the purpose of connection. Since the width of the mold is smaller than the crimping width, multiple crimping is required. It is cumbersome to press a mold after finishing one mold, and it requires a relatively large force to plastically deform the tension clamp and the wire at room temperature, which requires relatively high hydraulic pressure and high cost.
