Description

Technical Field

[0001] The utility model relates to a novel slow cooling guide groove device for high-speed wires, belonging to the field of metallurgical steel rolling. Background Art

[0002] A slow cooling guide trough refers to a device or apparatus used to control and adjust the temperature distribution and cooling rate of metal materials during the cooling process in a heat treatment process. It is used to control the thermal balance of metal materials during the cooling process. The slow cooling guide trough is an important equipment in the production process of high-speed wire rods. After the red steel wire rods are cooled by a water tank, they must pass through a slow cooling guide trough to achieve uniform temperature, thereby obtaining the required spinning temperature. However, the existing slow cooling guide troughs are designed to be very long based on the needs of cooling and the slow cooling line design length may even reach 90m. Therefore, due to the functional and structural limitations of the slow cooling guide trough itself, scratches on the wire rods often occur in the slow cooling guide trough, which directly affects the product quality.

[0003] Therefore, it is urgent to propose a new type of slow cooling guide groove device for high-speed wire to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection, including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: choose welding connection for fixed connection and hinge connection for detachable connection.

[0027] Specific implementation method 1: Combination Figure 1-7The present embodiment is described. A novel slow cooling guide groove device for high-speed wire rod in the present embodiment comprises a guide groove 1, a bracket 2 and a double-wheel guide device 3. The guide groove 1 has a guide groove channel 6 which passes through the front and back. The front side of the guide groove channel 6 is a bell mouth 4. The double-wheel guide device 3 is fixedly installed on the rear side of the guide groove 1 through the bracket 2. The double-wheel guide device 3 comprises two guide wheels 31 which are rotatably arranged in parallel on the bracket 2. The side walls of the guide wheels 31 are processed with arc-shaped guide wheel grooves 32. Two symmetrical arc-shaped guide wheel grooves 32 form a guide wheel channel 38. The cross-sectional area of ​​the guide wheel channel 38 is smaller than the cross-sectional area of ​​the guide groove channel 6. For example, the size of the guide wheel channel 38 is 3 mm smaller than the size of the guide groove channel 6. The diameter of the guide wheel channel 38 is 22 mm. The steel walking and guiding functions can be realized. The wire rod enters the channel from the bell mouth 4, and then passes through the arc-shaped guide wheel grooves 32 of the two guide wheels 31 and then passes out. Therefore, the red steel wire rod does not directly contact the guide groove 1 when walking in the guide groove, so as to avoid scratches. A plurality of legs 5 are fixedly mounted on both sides of the guide groove 1 for supporting and fixing the guide groove 1 .

[0028] The guide groove 1 can be improved by using the original guide groove, shortening the original guide groove to 90mm, and processing two M16 deep 30 threaded holes on the top and side of the end. The double-wheel guide device is provided with four corresponding mounting holes, which can be connected and fixed with M16x40 hexagon socket bolts to form a new guide groove device.

[0029] The bracket 2 includes an end plate 21 and a fixed plate 22. The fixed plate 22 is installed at the end of the guide groove 1 through the end plate 21. Two guide wheels 31 are rotatably arranged on the fixed plate 22. The end plate 21 is provided with a through hole 23. The through hole 23 has the same size as the guide groove and can be set to a diameter of 25 mm. A bell mouth is also provided on the front side of the through hole 23 to avoid collision during steel running. After the wire passes through the through hole 23, it enters between the arc-shaped guide wheel grooves 32 of the two guide wheels 31. When steel running, the height of the wire is higher than the guide groove channel 6, thereby avoiding contact between the wire and the guide groove and avoiding scratches.

[0030] The dual-wheel guide device 3 also includes a guide roller shaft 33, a bearing 34, an oil distribution ring 35, a spacer ring 36 and a locking nut 37. The guide roller shaft 33 is rotatably mounted with the guide wheel 31 through the bearing 34. The guide roller shaft 33 at both ends of the bearing 34 is respectively provided with an oil distribution ring 35 and a spacer ring 36. The guide roller shaft 33 is fixedly mounted on the fixed plate 22 through a locking nut 37.

[0031] Two rows of cooling water outlets 24 are provided on the end plate 21, and the cooling water outlets 24 are located above the guide wheel 31. A cooling water channel is built into the end plate 21, and one end of the cooling water channel is connected to an external cooling water source through a cooling water inlet 25. After the cooling water passes through the cooling water channel, it flows from the cooling water outlet 24 at the other end to the guide wheel 31 to cool the guide wheel. At the same time, the cooling water channel also serves the dual function of enhancing the heat exchange and heat dissipation of the device itself.

[0032] The bracket 2 is provided with an oil-gas lubrication pipeline, one end of which is connected to lubricating oil and gas through an oil-gas inlet 26 , and the other end of which is connected to the bearing 34 through an oil hole provided on the guide roller shaft 33 .

[0033] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined, and those skilled in the art can exhaust all possibilities based on the mathematical knowledge of arrangement and combination. Therefore, the present utility model will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present utility model.

[0034] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
