Insulation Adhesion Test Radial Cutting Device

Abstract

The invention discloses a radial cutting device for insulation adhesion samples, which includes a base, a top plate, a movable support, a column, a hand wheel and a wheel shaft, and is characterized in that the two ends of the column are respectively arranged on the base and the top plate. above; the movable bracket is set on the column; the wheel shaft is set on the top plate, the top is fixedly connected with the handwheel, and the bottom is screwed with the movable bracket; the A blade shaft is provided at the bottom of the movable support, and at least two blades are provided on the blade shaft; a pair of rolling shafts parallel to the blade shafts are provided on the base. As a processing auxiliary tool, the invention can effectively improve the efficiency, and make the size and technology of the sample better meet the requirements of the standard.

Description

technical field [0001] The invention relates to the field of cutting devices, in particular to a radial cutting device for insulated cables, in particular to a radial cutting device for insulation adhesion samples. Background technique [0002] In the "GB / T14049-2008 Rated Voltage 10kV Overhead Insulated Cable" standard, the insulation adhesion test specifies the size and process requirements of the sample. According to the national standard, first take a standard size overhead insulated cable sample, peel off the insulation layer at both ends of the sample, leave a 100mm insulation layer in the middle, and then conduct an adhesion test on the insulation layer. [0003] The method of peeling off the insulation layer is to mark the cutting position on the surface of the sample, first cut the insulation layer of the sample radially until it touches the wire; then make an axial cut, and finally peel off the insulation layer. Usually, the whole process is completed by workers, ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to manual measurement, there may be errors in the cutting position, resulting in the length of the insulating layer not meeting the standard requirements

[0005] 2. Due to the use of manual radial cutting, the consistency of the operation results is poor, which will also cause the length of the insulating layer to fail to meet the standard requirements; at the same time, there is also a deviation phenomenon that the cutting surface is not on the same plane, resulting in irregular cutting end faces

[0006] 3. When the length of the insulation layer of the sample cannot meet the standard requirements, the results of the insulation adhesion test cannot reflect the true performance of the product

The consequence is that on the one hand, products that meet the requirements are misjudged as unqualified, resulting in waste; on the other hand, products that do not meet the requirements are misjudged as qualified, which may cause safety addiction.

[0007] 4. Since the whole process is completed by workers, the work efficiency is low and the labor cost is relatively high, so it is very uneconomical
