Technical Field
The invention relates to the technical field of wire and cable processing.
Background
Wire and cable are wire products for transmitting electric energy, electric signals and realizing electromagnetic energy conversion. A cable generally comprises a core for transmitting power or electrical signals and a sheath for protecting and insulating. Cables having only one core and having a small diameter are generally called wires. The cable core in the cable is made of metal material with good conductivity, and is usually processed by copper (good conductivity) or aluminum (low cost).
In the existing production process of the wire and the cable, cold pressure welding is generally needed for processing, and the cold pressure welding is a welding method for enabling metal to generate strong plastic deformation to form a joint only by external pressure at normal temperature. The cold-press welding joint does not generate a softening zone, a heat affected zone and a brittle metal intermediate phase, so the cold-press welding joint has good electrical performance, the resistance of the joint changes little compared with that of a base metal, and the cold-press welding joint is widely used in the production of metal wires.
However, most of clamping mechanisms of the existing cold-pressing welding machine are simple in structure and poor in fixing effect, so that the cables are unstable during welding, and the welding effect is affected.
