Stripping device of cable insulation shielding layer

Abstract

The invention relates to a stripping device of a cable insulation shielding layer. A knife rest with adjustable height is connected with the upper part of a support in a sliding way, a knife installation wheel is arranged on the knife rest and can be used for annularly cutting a cable to be cut, two rollers are arranged at the lower part of the support and are in correspondence to the knife installation wheel, the rolling directions of the two rollers and the knife installation wheel are the same, an axial cutting device is arranged at the side part of the support, a knife is used for annularly cutting along the outer surface of a cable, the height of the knife rest is adjusted after cutting a certain depth, the cutting depth is adjusted according to demand, thus, the cutting accuracy of the cable insulation shielding layer can be improved, and the cut cable is axially cut by the axial cutting device so as to conveniently strip the insulation shielding layer. By such structure, secondary cutting and manual stripping work are avoided, the working efficiency is greatly improved, moreover, labor and time are saved, and the safety is high.

Description

technical field [0001] The invention relates to the field of cable laying tools, in particular to a device for stripping cable insulation and shielding layers. Background technique [0002] Substation maintenance, testing, and overhaul require the production of multiple cable terminals. Each cable terminal takes 3 hours to produce, and about 300 cable joints need to be produced each year, of which stripping the insulation shielding layer accounts for more than 60% of the total time. Since the thickness of the insulating shielding layer is only 1-2mm, the insulating shielding layer must be completely stripped when making the cable terminal, and the internal cable structure cannot be damaged. Therefore, how to increase the speed of stripping the cable insulating shielding layer has become an urgent problem. In the prior art Generally, the stripping work is performed manually. When the operator cuts the insulating shielding layer, the internal structure may be damaged, resultin...

AI Technical Summary

Problems solved by technology

Since the thickness of the insulating shielding layer is only 1-2mm, the insulating shielding layer must be completely stripped when making the cable terminal, and the internal cable structure cannot be damaged. Therefore, how to increase the speed of stripping the cable insulating shielding layer has become an urgent problem. In the prior art Generally, the stripping work is carried out manually. When the operator cuts the insulating shielding layer, the internal structure may be damaged, resulting in a decrease in the insulation of the cable and burying hidden dangers of accidents.

In addition, in order to solve this problem, people have invented a variety of cable insulation stripping tools, such as a cable sheath stripping tool that cuts the insulation layer along the axial direction of the cable. This stripping method is difficult to remove the cut insulation layer. Removal requires secondary cutting, the operation is more complicated, and it is not convenient for tool replacement and height adjustment, so the cutting accuracy of the insulating layer is low and the practicability is not strong
