Description

Technical Field

[0001] The invention relates to a joint device for rubber cable vulcanization and a use method thereof. Background Art

[0002] In the rubber-sheathed cable industry, the conductors used in production are mainly copper. The characteristic of copper is that it is easy to oxidize and turn black when encountering a high temperature and high humidity environment. At present, the production and manufacturing process of rubber-sheathed cables mostly uses a continuously vulcanized vulcanized pipeline as the main vulcanization processing method. This method is based on the vulcanized pipeline. The rubber wire machine extrude a traction sleeve, connect the traction sleeve with the rubber cable, and pass the rubber cable through the vulcanized pipeline. During production, 160° to 210° steam will be input into the pipeline. If there is a gap at the junction of the traction sleeve and the rubber cable, the water vapor in the pipeline will enter the interior of the rubber cable through the gap, and then oxidize the conductor. For this reason, it is urgent to prevent and eliminate the occurrence of the above defects. Summary of the invention
