Automatic Measuring Device for Conductivity of Wire Rod

Abstract

The invention discloses a wire rod electric conductivity automatic measuring device. The wire rod electric conductivity automatic measuring device comprises a first pinch roll and a second pinch roll both arranged at the same water level; at least two groups of diameter measuring rolls are arranged between the first pinch roll and the second pinch roll; a test sample clamp capable of clamping a test sample in a vertical lifting and dropping manner is arranged between the two groups of the diameter measuring rolls; a pair of grinding wheels which can be dropped and lifted vertically is arranged between the first pinch roll and the second pinch roll and located above the test sample clamp; the distance between the grinding wheels is greater than the width of the test sample clamp; a group of tips which can retractable horizontally to tightly support against the test sample is arranged below the first and second pinch rolls; the end parts of the tips are connected with a measuring part of an electric conductivity measurement instrument; a coarse correcting machine is arranged on one side of the first pinch roll while the second pinch roll is arranged on the other side thereof; a refined correcting machine is arranged between the coarse correcting machine and the first pinch roll. The test sample is linear after subjected to coarse correction and refined correction; test samples in unit length are cut by the grinding wheels; the whole measuring process is automatic; the measuring efficiency is not only increased, but the measuring precision is also improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to an automatic measuring device for electrical conductivity of a wire rod. Background technique [0002] For cable steel wire rods, the user hopes that the conductivity of each batch of steel can be reflected in the quality assurance certificate, but the measurement of the wire rod conductivity can only be done manually. The manual steps are: randomly take a 1.1m wire rod sample (generally the sample is curved) → scribing → grinding → measuring resistance → measuring the diameter of the wire rod → calculating the resistivity of the wire rod → calculating the measured electrical conductivity → reading the temperature and temperature coefficient of the measured steel at this time → calculating the steel Conductivity at room temperature of 20°C. [0003] Judging from the above steps, the measurement process is more complicated and imprecise, with more human subjective...
