The utility model has simple structure, realizes the quick, economic and grading inspection of the inner wall of the round hole of the guide slot through the quick inspection template of the abrasion loss of the inner wall of the round hole of the guide slot of the water cooling line, and provides necessary support for ensuring the smooth production; the abrasion of the inner wall of the round hole of the guide groove can be detected in place through reasonable grading.
Description
Technical Field
The utility model relates to a quick inspection template of high-speed wire rod production line water-cooling line guide slot round hole inner wall wearing and tearing volume.
Background
In order to ensure that the steel rolled piece obtains a metallographic structure satisfied by a customer, a water cooling line area is arranged behind a high-speed rolling area in a high-speed wire rod production line. When the rolled piece passes through the area, the water quantity of the water cooling area water cooling nozzle guide groove is adjusted or the anhydrous soaking sections with different lengths are arranged, so that the process is rapidly cooled, and finally, products with different mechanical properties are obtained after the air quantity of the air cooling line area is adjusted. Because the inner walls of the circular holes of various guide grooves (a forward nozzle guide groove, a reverse nozzle guide groove, a water-cooling nozzle guide groove, an extension nozzle guide groove and a soaking guide groove) in the water-cooling line area are in long-term direct contact with a rolled piece (up to 100 m/s) running at high speed, the inner walls of the circular holes of the guide grooves are extremely easy to wear. Uneven wear of the inner wall of the round hole of the guide groove and overlarge guide groove are easy to cause the rolled piece to shake and break in the operation process, thereby causing accidents such as product scratching, steel piling and the like. Therefore, the inner wall of the round hole of the guide groove must be periodically inspected for abrasion and scrapped when the abrasion exceeds a set standard. When a production line worker inspects the abrasion of the inner wall of the circular hole of the guide groove, the direct size of the inner hole of the guide groove is usually directly measured by a ruler, and the abrasion conditions of other parts of the inner wall of the circular hole cannot be measured and judged.
SUMMERY OF THE UTILITY MODEL
The purpose of the invention is as follows: the utility model provides a high-speed wire rod production line water-cooling line guide slot round hole inner wall wearing and tearing verifying attachment, the device have solved the ruler and have measured guide slot hole diameter size and the unable problem of measuring judgement of the other position wearing and tearing circumstances of round hole inner wall.
The technical scheme is as follows: the utility model discloses a high-speed wire rod production line water-cooling line guide slot round hole inner wall wearing and tearing verifying attachment, all be equipped with the bellied inspection template of semicircle, each including each edge the bellied diameter of semicircle is respectively guide slot round hole inner wall and is scrapped wear dimension to each not waiting to reach between the original design size for the most.
In order to ensure the accuracy of the measuring result, the diameter of each semi-circular arc protrusion is equally designed according to the difference between the maximum scrapped wear dimension of the inner wall of the circular hole of the guide groove and the original design dimension, for example, the difference between the diameters of two adjacent circular arcs is 1 mm.
Wherein, the checking template can be polygonal, at least trilateral, preferably quadrilateral.
In order to conveniently check the abrasion loss of each circular aperture, each semicircular arc is marked with a diameter size mark, and the circular arc diameter mark is positioned in the blank of the template right below the circular arc diameter mark.
And each semicircular arc bulge is positioned in the middle of each edge of the inspection template.
When the guide groove measuring tool is used, the guide groove is placed in the grading arc convex edge on the template for measurement, for example, the maximum scrapped size of the inner wall of the guide groove is 15 mm, the arc diameter of the convex edge is increased progressively according to the standard of 1 mm according to the original design diameter size of 11 mm of the inner wall of the circular hole of the guide groove, and the inner wall of the circular hole of the guide groove can be quickly judged to be positioned between the grades through measurement so as to judge whether to continue to be used, replaced.
Has the advantages that: the utility model has simple structure, realizes the quick, economic and grading inspection of the inner wall of the round hole of the guide slot through the quick inspection template of the abrasion loss of the inner wall of the round hole of the guide slot of the water cooling line, and provides necessary support for ensuring the smooth production; the abrasion of the inner wall of the round hole of the guide groove can be detected in place through reasonable grading.

Detailed Description
Referring to fig. 1 and 2, an embodiment the high-speed wire rod production line water-cooling line guide slot round hole inner wall wearing and tearing verifying attachment, including each edge all be equipped with the protruding 401 quadrangle inspection template 301 of semicircle, the design is equallyd divide to the diameter of the protruding 401 of each semicircle according to the difference between the biggest condemned wearing and tearing size of guide slot 101 round hole inner wall and original design size, the protruding 401 diameter of two adjacent circular arcs differs 1 millimeter, and each the protruding 401 of semicircle marks diameter size mark, and the mark is located its under template blank department. Wherein each of the semicircular arc protrusions 401 is located at the middle position of each edge of the inspection template 301.
As shown in FIG. 3, the water cooling line area of the high-speed production line is partially schematic, and the rolled piece 101 and the guide groove 102 (which are assembled by an upper piece and a lower piece and can be directly separated) are arranged. During production, the rolled piece is in direct contact with the guide groove of the water cooling line, so that the inner wall of the round hole of the guide groove is easily abraded.
As shown in fig. 4, a structural schematic diagram of the measurement of the abrasion loss of the circular hole in the prior art is shown, and before the improvement, a worker can measure the upper part of the circular arc of the guide groove 101 by holding the straight edge 201 by hand, and cannot observe the abrasion loss of other parts of the inner wall of the circular arc.
The utility model discloses a theory of operation does: the circular arc protrusion 401 of the guide slot inspection template is placed into the worn guide slot 101. Because the diameter difference of each arc protrusion 401 is only 1 mm, if one of the two adjacent protrusions with a smaller diameter can be completely placed on the inner wall of the guide groove 101 after the guide groove is worn, and the other protrusion with a larger diameter cannot be completely placed on the inner wall of the guide groove 101 after the guide groove 101 is worn, it can be determined that the size of the inner wall of the guide groove is between the diameters of the two protrusions after the guide groove 101 is worn. If the maximum diameter bulge can be completely put into the guide groove 101 to be worn, the inner wall of the guide groove is judged to be worn too much and discarded.
