Abstract

The invention relates to a high-precision welding system for a metal sheath for a fireproof cable, which comprises a workbench, and an edge trimming device, a wire wrapping device, a welding joint device and a cooling device which are sequentially arranged on the upper surface of the workbench. The welding joint device comprises a detection mechanism and a welding mechanism. The welding mechanism comprises an adjuster fixedly connected to the workbench, a fine adjustment component connected with the adjuster and a welding head connected with the fine adjustment component. The detection mechanism comprises a visual tracking system, the visual tracking system can drive the fine adjustment component to drive the welding head to reciprocate in the horizontal direction, and a welding edge line cleaning device is arranged on the front side of the welding joint device. Before welding, the side edge of a metal band is treated and deburred through the welding edge line cleaning device, the situation that since powder accumulation occurs at the butt welding joint position, the welding quality is affected is avoided, the butt joint position of the metal band is tracked through the visual tracking system in the welding process and fed back to the fine adjustment component for real-time adjustment, and the phenomenon of weld skip is avoided.

Description

Technical field [0001] The present invention relates to the field of cable production, in particular, to a high-precision welding system for metal sheath for fireless cables. Background technique [0002] Mineral insulation cables are an inorganic material cable, and the main materials use inorganic minerals or mineral compounds, which generally have a high melting point, and it is not easy to combust or combustion under flame conditions, gradually become a hot spot in recent years. The mineral insulated cable is formed by a copper conductor, an inorganic insulating material, and a seamless copper tube that is welded to a copper band vertical package. The conventional cable sheath is unstable in the weld at the time of welding, resulting in poor waterproof performance, bending, and the weld is easy to crack when burning. Inventive content [0003] The technical problem to be solved by the present invention is to overcome the shortcomings in the prior art, providing a high-precis...
