The invention discloses a heat dissipation and lubrication device for a pressing die of a power cable. The heat dissipation and lubrication device comprises an upper support and a lower support. The upper support and the lower support are connected with the central fixing frame. Four arc-shaped pressing plates are equidistantly mounted on the central fixing frame in the circumferential direction.Driven gears connected with the arc-shaped pressing plates are arranged between the upper support and the lower support, and a driving gear driven by a motor to rotate is installed on the lower support, so that the driven gears support the four arc-shaped pressing plates to be closed under the driving effect of the driving gear so as to compress and bundle the power cable. The lubricating lanternring of the annular structure is used for spraying lubricating oil to the power cable in an all-around mode so that the power cable can be lubricated. The spraying lantern ring of an annular structureis used for carrying out all-around cold water spraying on the power cable, so that the power cable is cooled under the effect of cold water. And then the power cable adsorbed with the cold water isblown in all directions by utilizing the blowing lantern ring with the annular structure, so that efficient blowing drying is realized.
Description
technical field [0001] The invention relates to the technical field of power cable processing, in particular to a heat dissipation and lubricating device for a pressing mold of a power cable. Background technique [0002] The use of power cables has a history of more than 100 years. It is a cable used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In the power line, the proportion of the cable is gradually increasing. Specifically, the power cable is the medium used to transmit and distribute high-power electric energy in the main line of the power system. Because the power cable will be pulled by a large external force during installation and use, it is very easy to have a certain degree of structural expansion and contraction. In order to ensure the stretching and t...
