Batch testing machine for torsion durability of wires and cables

Abstract

The invention relates to the technical field of wire and cable testing and particularly relates to a wire and cable torsion durability batch testing machine. The testing machine comprises a workbench, a torsion detection device and a wear resistance detection device, wherein the torsion detection device is arranged on an upper end face of the workbench, and the wear resistance detection device is arranged in the middle of the torsion detection device. According to the testing machine, distortion resistance test detection and wear resistance test detection can be carried out on wires and cables, that is to say, a torsion test or a wear test can be carried out on the wires and cables independently, and the torsion test and the wear test can also be carried out on the wires and cables step by step, so the application range of the device is widened; batch test detection can be carried out on wires and cables in an annular distribution mode, test efficiency is improved, a torsion angle of the wires and cables can be controlled when the torsion test is carried out on the wires and cables, and the test effect of detecting the wires and cables is further improved.

Description

technical field [0001] The invention relates to the technical field of wire and cable testing, in particular to a batch testing machine for twisting durability of wires and cables. Background technique [0002] With the continuous development of the modern economy and society, people's requirements for electricity are getting higher and higher. On this basis, the quality requirements of the power system for wires and cables are also gradually increasing. In order to ensure the normal operation of the power system, the country's testing requirements for wires and cables It is also constantly improved and improved. The quality of wires and cables in the entire work process of the power system is an important guarantee to ensure the stable operation of the power system. Therefore, it is particularly important to detect the twist durability of wires and cables. [0003] At present, the twist durability test is mainly to test the twist durability of the wire and cable by twisting...

AI Technical Summary

Problems solved by technology

[0003] At present, the twist durability test is mainly to test the twist durability of the wire and cable by twisting the wire and cable for a certain number of times. The existing wire and cable twist durability testing machine still has the following problems: a. The existing wire and cable twist Most of the durability testing machines can only perform torsion tests on wires and cables, but in actual use, sometimes twisting and friction coexist in the cables, so while performing torsion tests on the cables, increase the wear resistance of the cables It is also very necessary; b. Most of the existing testing machines test the wires and cables alone, and have not done it in batches, resulting in low test and detection efficiency. At the same time, most of the current twist durability testing machines test the wires and cables at a certain angle Different torsion angles cannot be set during the torsion test, which further improves the test effect of detecting wires and cables
