Peeling method of insulated lead of distribution wire and peeling knife thereof

Abstract

The invention relates to a peeling method of an insulated lead of a distribution wire and a peeling knife thereof. The peeling method adopts a jaw vice-shaped peeling knife, wherein the inside of a knife block of the peeling knife is provided with an upper knife block and a lower knife block which are arranged oppositely in vertical direction and can move relatively; symmetrical cambered concave cutting knife edges are formed on the side mouths of both knife blocks; the inner side of each knife block is provided with a single cutting knife edge; the cutting knife edges are connected with an electric hot plate to perform direct-current preheating for 8 to 10 minutes, and the temperature is controlled between 95 and 125 DEG C; and finally, the cutting knife edges are sleeved on a to-be-peeled insulated lead and are fed simultaneously through screwing a handle to cut in an insulation layer of the insulated lead and peel off the insulation layer. The peeling method has the advantages that the method not only improves the knife structure, but also switches on a direct current power supply to heat the cutting knife edges and cut the insulated lead through rotary feed; and at the same time, the insulation layer of the insulated lead is heated and softened during feed and a rotary knife body separates the insulation layer from the core of the insulated lead, thereby reducing the hardness of the insulation layer and facilitating the feeding, cutting and peeling off.

Description

technical field [0001] The present invention relates to a construction tool for distribution lines of electric power systems. Specifically, the present invention relates to a method for stripping insulated conductors of distribution lines and a stripping knife thereof. The method for stripping insulated conductors of power distribution lines and the stripping knife can be It is convenient to peel off the sheath of the outer insulating layer of the insulated wire without damaging the wire itself. Background technique [0002] The development direction of power system distribution lines is insulation. At present, the insulation rate of distribution lines in the domestic power system is increasing year by year, and some cities above the regional level have also implemented insulation of distribution lines, and it is constantly expanding. [0003] As the insulation rate of distribution lines continues to increase, the construction requirements and methods of insulated wires are...

Problems solved by technology

[0005] In addition, there are also such influencing factors: that is, in lower temperature weather, the hardness of the insulation layer increases, and the existing wire stripper for power line construction is difficult work, even with a knife

As a result, sometimes the method of hard cutting with an electrician's knife during construction is easy to damage the metal part of the wire and cause hidden dangers, and it is very unsafe
