[0002] The water cooling of the water tank at the rear of the finishing mill is one of the important equipment for post-rolling controlled cooling of high-speed wire rod rolling mill products. Its main function is to rapidly cool the rolled wire rod as required to obtain wire rod products with mechanical properties meeting the requirements. There is a recovery section guide groove between the water tanks. This is mainly because the temperature difference between the core and the surface of the rolled piece is relatively large when it comes out of the water tank. Giving the rolled piece a certain tempering time can reduce the temperature difference between the core and the surface of the rolled piece.
[0003] The existing recovery section guide grooves generally have a fixed inner diameter size and are only applicable to high-speed wire rods of specific sizes. According to the arrangement of the rolling production plan, wire rods with large and small outer diameters often need to be produced alternately. Therefore, it is often necessary to replace two guide grooves with different inner diameters, and the guide groove replacement time is relatively long. This not only causes a large workload for the operators but also slows down the production efficiency of the enterprise. For this reason, the utility model proposes a turnover guide groove for the post-rolling water cooling recovery section of a high-speed wire rod rolling mill to solve the above problems. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] As Figures 1-5 shown, the present invention provides a technical solution: a turning guide groove for the post-rolling water cooling recovery section of a high-speed wire rod rolling mill, including a base 1, a first cover plate 2 is arranged on the top of the base 1, a second cover plate 3 is arranged at the bottom of the base 1, rotating members 4 are arranged on both the left and right sides of the base 1, a plurality of first bosses 5 are equidistantly arranged on both the left and right sides of the base 1, a plurality of second bosses 6 are equidistantly arranged on both the left and right sides of the first cover plate 2, and a plurality of third bosses 7 are equidistantly arranged on both the left and right sides of the second cover plate 3. During use, the entire recovery section guide groove can be installed between two cooling water tanks of a high-speed wire rod finishing mill.
[0024] Among them, a first base groove 11 is opened on the left side of the top of the base 1, a first sealing groove 21 is opened at the bottom of the first cover plate 2, the bottom of the second base groove 12 is in contact with the top of the second sealing groove 31, and the inner diameters of the second base groove 12 and the second sealing groove 31 are the same. The first base groove 11 and the first sealing groove 21 together can form a guide groove with a smaller inner diameter, which can be used to pass a wire rod with a smaller outer diameter.
[0025] Furthermore, a first flared opening 13 is opened on the left side of the inner wall of the first base groove 11, a third flared opening 22 is opened on the left side of the first sealing groove 21, the top of the first flared opening 13 is in contact with the top of the third flared opening 22, and the first flared opening 13 and the third flared opening 22 together can form a flared opening with a smaller inner diameter, which can facilitate guiding a wire rod with a smaller outer diameter into the smaller guide groove.
[0026] Among them, a second base groove 12 is formed at the bottom of the base 1, and a second sealing groove 31 is formed at the bottom of the second cover plate 3. The top of the first base groove 11 is fitted with the bottom of the first sealing groove 21. The inner diameters of the first base groove 11 and the first sealing groove 21 are the same. The second base groove 12 and the second sealing groove 31 together can form a guiding groove with a larger inner diameter, which can be used to pass a wire with a larger outer diameter.
[0027] Furthermore, a second flaring opening 14 is formed on the left side of the inner wall of the second base groove 12, and a fourth flaring opening 32 is formed on the left side of the second sealing groove 31. The bottom of the second flaring opening 14 is fitted with the top of the fourth flaring opening 32. The second flaring opening 14 and the fourth flaring opening 32 together can form a flaring opening with a larger inner diameter, which can facilitate guiding a wire with a larger outer diameter into the larger guiding groove.
[0028] Among them, the rotating member 4 includes a bearing 41. The bearing 41 is embedded in the outer wall of the base 1.

In this way, not only the workload of the operator can be reduced, but also the production efficiency of the enterprise can be guaranteed.
[0030] Among them, the first boss 5, the second boss 6, and the third boss 7 are fixedly connected by bolts. The first boss 5, the second boss 6, and the third boss 7 correspond to each other one by one. During installation, this recovery section guiding groove can be placed on the support beam. The first boss 5, the second boss 6, and the third boss 7 can all play a role in limiting the left and right positions, ensuring the concentricity of the rolling line. At the same time, the bolts can also be screwed out to quickly disassemble the base 1, the first cover plate 2, and the second cover plate 3, so as to facilitate cleaning the inside of the first base groove 11, the first sealing groove 21, the second base groove 12, and the second sealing groove 31.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
