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.

Embodiment Construction

[0037] Such as Figure 1-7 , the existing cable includes several copper cores (2), an insulating layer (4) covering the copper cores (2), an armor layer (1) covering all the copper cores (2), and an armor layer Filling layer (3) between (1) and copper core (2). The invention realizes the automatic stripping of the existing cables, thereby obtaining an insulating layer with uniform thickness.

[0038] Such as figure 1As shown, the cable insulation layer sample cutting device of the present embodiment includes a cutting insulation device 11; The cutting insulation machine head 50 center hole on the insulation machine base 49 and the insulation cutting tailstock 54 center holes, the guide rail that is arranged between the insulation cutting machine head 50 and the insulation cutting tailstock 54, moves and is arranged on the guide rail and is connected with the insulation cutting tailstock. The center hole of the seat 54 is coaxial with the insulation-cutting centering frame 5...

Abstract

The invention relates to a cable insulation layer sample cutting device and method. A cutting insulation device is arranged, and comprises a cutting insulation base for acquiring a strip insulation layer by cutting, a cutting insulation head center hole and a cutting insulation tail center hole coaxially arranged on the cutting insulation base, a guide rail arranged between the cutting insulationhead and the cutting insulation tail, a cutting insulation strengthening frame movably arranged on the guide rail and coaxial with the cutting insulation tail center hole, cutting insulation clampingclaws arranged at the cutting insulation head center hole and the cutting insulation tail center hole respectively, a cutting insulation top inserted to the center hole and a cutting insulation three-axis cutter holder arranged on the cutting insulation base, located at one side of the guide rail, with the head having the same height with the center hole and driven by a lead screw nut mechanism. The design is reasonable, the structure is compact and the use is convenient.

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. [0003] In cable testing, traditional cable insulation sheet sampling methods include three methods: radial sampling, axial sampling, and insulating material pres...
