Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

When the finishing mill, reducing mill and sizing mill adopt centralized transmission, the finishing mill, reducing mill and sizing mill are limited by the centralized transmission structure, and it is difficult to independently adjust the operation of each finishing mill, reducing mill and sizing mill. The rolling speed lacks the flexibility of adjustment, and it is difficult to meet the needs of different wire rods for different rolling speeds. However, when the finishing mill, reducing machine and sizing machine are all independently adjusted, on the one hand, the number of driving devices is increased, and the investment cost is increased; There will be a speed error in the process, and when there are multiple rolling mills, the speed error will gradually superimpose and act on the wire rod, which is not conducive to controlling the production quality of the wire rod. The present application provides a high-speed wire rod production system, which is mainly used to solve the problem of rolling speed control of a rolling mill.

Please refer to FIG. 1 to FIG. 7 , an embodiment of the present application provides a high-speed wire rod production system, including: a finishing rolling unit 1 arranged in sequence, the finishing rolling unit 1 includes a plurality of groups of finishing rolling modules 11 arranged in a row and a first driving device 12 disposed on each of the finishing rolling modules 11, the first driving device 12 is used to drive the corresponding finishing rolling module 11; the diameter reducing unit 2, the diameter reducing unit 2 includes at least A set of reducing modules 21 and a second driving device 22 arranged on the reducing module 21, the second driving device 22 is used to drive the corresponding reducing modules 21; the sizing unit 3, the The sizing unit 3 includes at least one set of sizing modules 31 and a third driving device 32 disposed on the sizing module 31 , and the third driving device 32 is used to drive the corresponding sizing module 31 .

On the whole, when the high-speed wire rod production system described in this application is used, the finishing rolling operation of the high-speed wire rod is carried out by the finishing rolling unit 1, the diameter reduction operation of the high-speed wire rod is performed by the diameter reducing unit 2, and finally the high-speed wire rod is subjected to the diameter reduction operation by the sizing unit 3. Carry out sizing operation. The high-speed wire rod can be processed into the desired shape and size by the finishing rolling unit 1, the reducing unit 2 and the sizing unit 3. Specifically, four sets of finishing rolling modules 11 can be set in the finishing rolling unit 1, a set of reducing modules 21 can be set in the reducing set 2, and a set of sizing modules 31 can be set in the sizing set 3 . Of course, the designer can also adjust the number of finishing rolling modules 1 , reducing modules 21 and sizing modules 31 as required, which is only an example here, and other setting methods are not limited.

Since the high-speed wire rod will be deformed between each unit, the rolling speed of the high-speed wire rod by each unit is different. In order to obtain better rolling quality of high-speed wire rods, it is necessary to adjust the rolling speed of each unit to make the rolling speed of each unit more matched to increase the rolling quality of high-speed wire rods. The designer can adjust the rolling speed of each unit according to the rolling process, which is not limited here.

Specifically, please refer to FIG. 1 to FIG. 7 , the high-speed wire rod production system may include: a finishing rolling unit 1 ; a diameter reducing unit 2 ; and a sizing unit 3 .

In this embodiment, since the high-speed wire rod will be deformed and elongated during the finishing rolling process, in order to better roll the high-speed wire rod, each finishing rolling module needs to be controlled by the first driving device 12 provided on the finishing rolling module 11 11, so that the rolling speed of the four groups of finishing rolling modules 11 can be matched with the production requirements of high-speed wire rods.

Wherein, when the high-speed wire rod is rolled, it will be extended to increase the line speed, so that the rolling speed of the finishing rolling module 11 needs to be gradually increased accordingly. The designer can pre-store the mathematical relationship between the elongation during the high-speed wire rod rolling and the rolling speed required by the finishing rolling module 11 . When rolling the high-speed wire rod, the operator can control the rolling speed of the finishing rolling module 11 through the first driving device 12 according to the aforementioned mathematical relationship. Of course, the designer can also adopt other corresponding relationships to determine the rolling speed of the finishing rolling module 11 , which is not limited here.

In this embodiment, referring to FIG. 1 and FIG. 2 , the finishing rolling module 11 includes two finishing rolling mills 111 arranged on top of each other, and the first driving device 12 includes a first motor 121 and a first transmission 122 .

By using the first driving device 12 to drive the two finishing mills 111 synchronously, the rolling speed error between the two finishing mills 111 can also be eliminated, so that the finishing mills 111 can roll high-speed wire rods more stably and accurately. When in use, the rolling speed of the corresponding finishing rolling mill 111 can be controlled by the first driving device 12, so as to increase the flexibility of the rolling speed adjustment of the finishing rolling module 11, so that a variety of different rolling mills can be formed between the finishing rolling modules 11. The ratio of rolling speed is convenient to match the elongation of the high-speed wire rod with the rolling speed of the finishing mill 111, thereby improving the rolling quality.

Among them, the production of high-speed wire rods with different diameters has different requirements on the number of finishing rolling modules 11 used. For example, when producing small-sized wire rods, four sets of finishing rolling modules 11 need to be used to roll high-speed wire rods to reduce the diameter of the high-speed wire rods. When producing large-scale wire rods, all 4 groups of finishing rolling modules 11 are not required to roll high-speed wire rods, and the high-speed wire rods can be controlled to pass through any finishing rolling module 11 to reduce the deformation amount of high-speed wire rods. The finishing rolling module 11 can independently adjust the rolling speed to meet the wire rolling speed and elongation requirements. When the high-speed wire rod passes part of the finishing rolling modules 11, since each finishing rolling module 11 is provided with the first driving device 12, the passing finishing rolling modules 11 can be independently closed in advance without adjusting the rolling speed. This can save production preparation time and improve work efficiency, an advantage that is not available with centralized transmission.

When in use, the rolling speeds of the two reducing machines 211 can be independently adjusted through the two second driving devices 22 , so as to realize flexible adjustment of the rolling elongation between the two reducing machines 211 . And the elongation can be adjusted by replacing the roller rings on the reducer 211 or adjusting the hole pattern between the roller rings, so as to handle wires of different diameters. By independently arranging the second drive device 22 on the reducer 211, the rolling speed of each reducer 211 can be independently adjusted by the second drive device 22, so that the speed ratio between the two reducers 211 is relatively high. The large adjustment range can meet the rolling speed required for the extension change after the wire is rolled.
