Finalizing method of sprinkling temperature-lowering finalizing device for electric power cable external insulation layer processing

Abstract

The invention discloses a finalizing method of a sprinkling temperature-lowering finalizing device for electric power cable external insulation layer processing. An electric power cable insulation layer after completion of processing enters a temperature-lowering sprinkling water box, a circulating water hot water pump conveys 40 DEG C-50 DEG C hot water through a sprinkling water hot water pipe to continuously sprinkle the hot water to all sprinkling cloth curtains via sprinkling heads, so as to make the sprinkling cloth curtains fit on the upper face of the soft electric power cable insulation layer, the sprinkling cloth curtains are used for temperature lowering and cooling of the insulation layer, temperature lowering is performed until the surface of the insulation layer is finalized,and the electric power cable insulation layer with the surface finalized enters a next processing procedure through a wire-passing soft gasket in a wire outlet. The sprinkling temperature-lowering finalizing device is provided with the sprinkling heads and the cloth curtains; when the soft electric power cable insulation layer with higher temperature passes through, the surface layer of the softinsulation layer is finalized by the sprinkling cloth curtains, and the surface layer of the insulation layer is guaranteed to have a certain toughness and strength, the design is reasonable, unqualified products are reduced, the operation is convenient, and the quality of the products can be improved.

Description

technical field [0001] The invention relates to the shaping and cooling of the processing equipment for the outer insulating layer of electric cables, in particular to a shaping method of the spraying cooling and shaping device for the processing of the outer insulating layer of the electric cables. Background technique [0002] At present, when the outer insulating layer of the existing power cable is processed, the processing temperature of the outer insulating layer of the processed power cable is relatively high, the insulating layer is soft, and the surface cannot touch hard objects, and the outer insulating layer of the power cable cannot be guided during processing. The materials with higher temperature on the outer insulating layer of power cables are shaped through a slow cooling process. Generally, warm water in a heated water tank is used to shape the outer insulating layer of high-temperature cables. The soft insulating layer causes damage, deformation, unqualifi...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the processing temperature of the processed outer insulating layer of power cables is relatively high, the insulating layer is soft, and the surface cannot be touched by hard objects. Because the material with high temperature of the outer insulation layer of the power cable is shaped through a slow cooling process, generally the warm water in the heated water tank is used to shape the high-temperature outer insulation layer of the cable, but it is easy to place the guide roller in the water of the heated water tank It will damage and deform the soft insulation layer with high temperature, cause the product to be unqualified, and cause a lot of losses to the enterprise. Through reasonable design, it provides a method for shaping the outer insulation layer of power cables by spraying and cooling. The invented spray cooling and shaping device is equipped with a spray head and a cloth curtain. When the soft insulation layer with a higher temperature of the power cable passes through, the surface layer of the soft insulation layer is shaped by the spray curtain, and the soft insulation layer with a higher temperature of the power cable passes through it. After the surface of the insulating layer is shaped, it enters the circulating water for cooling and shaping to ensure that the surface of the insulating layer has a certain toughness and strength. When the power cable enters the heated water tank, the guide roller will not damage or deform the insulating layer. The design is reasonable , reduce unqualified products, easy to operate, and can improve product quality
