Cable insulating layer sample cutting device and method

Abstract

The invention relates to a device and a method for cutting a sample of a cable insulation layer, which includes an insulation cutting device; The center hole of the insulation-cutting head and the center hole of the insulation-cutting tailstock, the guide rail arranged between the insulation-cutting head and the insulation-cutting tailstock, the mobile set on the guide rail and the copper core hole coaxial with the center hole of the insulation-cutting tailstock Insulation-cutting centering frame, insulation-cutting jaws respectively arranged at the center hole of the insulation-cutting machine head and at the center hole of the insulation-cutting tailstock, the insulation-cutting tip inserted in the center hole, and the insulation-cutting base set on the guide rail one The side and the cutter head are of the same height as the center hole and are driven by the lead screw nut mechanism to cut the insulation three-axis cutter holder; the invention has reasonable design, compact structure and convenient use.

Description

technical field [0001] The invention relates to a device and a method for cutting a cable insulating layer sample. Background technique [0002] At present, wire and cable are wire products that transmit electric (magnetic) energy, transmit information, and realize electromagnetic energy conversion. They are widely used in various fields of national economy and are known as the "vessel" and "nerve" of the national economy. At present, the output value of my country's wire and cable industry exceeds one trillion yuan. It is one of the largest supporting industries in the national economy and the second largest industry in the machinery industry after the automobile industry. Wire and cable products are widely used in electricity, energy, transportation, and communications. , automobile and petrochemical industries.

Problems solved by technology

[0003] In cable testing, traditional cable insulation sheet sampling methods include three methods: radial sampling, axial sampling, and insulating material pressing. The width of the cable is limited. The above two methods can only achieve small-scale sampling of the cable insulation sheet, and cannot test some electrical properties of the cable, such as dielectric constant, volume resistivity, especially the space charge of the flexible DC cable, etc.
