Caliper guide

Abstract

Provided is a guide-and-guard apparatus used at the outlet of a diameter-measuring instrument. The guide-and-guard apparatus comprises a guiding conduit (10) through which wire material passes, and an air current guidance mechanism, provided near the material outlet of the guiding conduit (10), for guiding the air current and the material to advance in the same direction. By means of the guidance provided by the air current guidance mechanism, the air currents in the guiding conduit (10) cavity all advance together with the material, or the wire rod, and can easily be discharged from the guiding conduit (10) cavity. In this way, high-temperature foreign matter and iron shavings are prevented from falling onto the guiding conduit (10) wall whereon they can form residue and increase frictional force, as well as affect the dimensions of the guiding conduit (10). Once the guiding conduit (10) and the entire guide-and-guard apparatus are mounted, the instrument can be used for an extended period, reducing the number of repairs or adjustments, and thereby allowing for a long service life and reduced maintenance costs.

Description

technical field [0001] The invention relates to a guide device used for the outlet of a caliper. Background technique [0002] In the metallurgical industry, during the binding and forming process of wires and rods, it is necessary to use a caliper to detect their radial dimensions, especially a caliper for real-time detection of the wire during the rolling process, because the newly drawn wire is at high temperature Therefore, when passing the caliper, it is inevitable that there will be sparks, high-temperature impurities, iron filings splashing and falling and accumulating on precision parts such as light-transmitting mirrors, which will pollute the testing equipment, reduce the detection accuracy, and even cause imaging failure. Serious consequences such as detection failure. [0003] In order to avoid scratching and damaging the caliper due to the jumping of the wire bar, and to avoid scratching between the wire bar and the caliper, reduce impurities and iron filings, ...

AI Technical Summary

Problems solved by technology

[0005] However, in practice, the dust and impurities in the caliper cannot be discharged smoothly, which affects the reliability and accuracy of the detection; the dust, impurities and high-temperature iron filings in the guide keep falling and sticking On the wall of the guide tube, slag accumulates continuously due to its own high temperature, which will cause the wall of the guide tube to be rough and increase the friction with the wire. When the slagging accumulates to a certain extent, the lumen of the guide tube will change small, the wire travels unstable, increasing the risk of scratching the caliper, and even losing the functions of the caliper and guide

Generally speaking, it is difficult to maintain the cleanliness of the caliper equipment and guides in the prior art, which affects the reliability of detection
