Description

Technical Field

[0001] The utility model relates to an extruder bracket for a cable flexible joint, belonging to the field of cable processing equipment. Background Art

[0002] In recent years, with the development of the national economy, long-distance ultra-high voltage direct current transmission projects have been widely used in China. Due to the limitations of production length and transportation conditions, a single cable cannot meet the actual needs of the project, so cable joint manufacturing technology becomes particularly important. Especially for cables in special use scenarios such as submarine cables, they may need to withstand certain external forces (such as bending, stretching) and chemical effects (such as seawater corrosion). Ordinary joint structures will be more prone to cracks, and the consequences of cracks will also be easier and faster to develop further (such as water tree reactions in seawater, causing insulation breakdown).

[0003] The current mainstream technology "two-step method" is to prepare cable flexible joints, that is, first complete the filling and shaping of the insulating material in the injection molding device, then complete the cross-linking of the molded structure in the cross-linking mold, and finally degas the flexible joint. In the process of filling and shaping the insulating material, an insulating material extruder is indispensable. When the extruder and the cable flexible joint are aligned and locked, the flexibility of manual adjustment is poor, and it is difficult to align the two effectively. In addition, the strong vibration caused by the excessive extrusion force of the extruder cannot be avoided, which seriously affects the quality of the product. Utility Model Content
