Description

Technical Field

[0001] This utility model relates to the field of bar and wire rolling technology, and in particular to a high-efficiency bar and wire rolling cooling device. Background Technology

[0002] Bar and wire rod rolling is a metal plastic processing technology, mainly used to roll raw materials such as steel billets through a series of rolling mills. In bar and wire rod rolling, the rolling and cooling process has a crucial impact on product quality and production efficiency.

[0003] In traditional rolling cooling, static nozzles are often used to spray bars and wires. Although this method can achieve basic cooling, the limited spray angle makes it impossible to dissipate heat from all directions, resulting in uneven cooling. Therefore, a high-efficiency rolling cooling device for bars and wires is proposed. Utility Model Content

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0027] Reference Figures 1-5 As an embodiment of the present invention, a high-efficiency rolling cooling device for bar and wire rod is provided, which includes: a housing 1, a turntable 7 rotatably connected to one side of the housing 1, and an annular block 2 fixedly connected to the other side;

[0028] An annular block 2 is rotatably connected to an annular water tank 3 in a sealed manner. An annular cavity is formed between the annular block 2 and the annular water tank 3. A water channel 2a and a through hole 3a are respectively opened on the annular block 2 and the annular water tank 3 to connect to the annular cavity. A water inlet pipe 4 connected to the water channel 2a is fixedly connected to the annular block 2. The water inlet pipe 4 passes through the shell 1. A water supply pipe 5 is fixedly connected between the annular water tank 3 and the turntable 7. The water supply pipe 5 is connected to the annular water tank 3. Multiple sets of nozzles 6 are fixedly connected to the water supply pipe 5.

[0029] The rotating shaft connecting the turntable 7 and the housing 1 is a hollow shaft and extends out of the housing 1. The hollow shaft is used to provide a channel for the rod and wire to pass through the device. A drive mechanism 9 for driving the turntable 7 to rotate is fixed at the bottom of the housing 1. The housing 1 has an opening for the rod and wire to pass through at the position opposite to the inner hole of the annular block 2. When in use, the rod and wire pass through the device through the opening of the housing 1, the inner hole of 2 and the hollow shaft of the turntable 7.

[0030] When the turntable 7 rotates, it drives the annular water tank 3 to rotate synchronously through the water supply pipe 5. During the rotation of the annular water tank 3, it is always connected to the annular cavity through the through hole 3a. Here, when the annular water tank 3 rotates, the coolant can continuously enter the water tank 3 through the water inlet pipe 4, water channel 2a, annular cavity, and through hole 3a. Therefore, multiple sets of nozzles 6 can spray coolant while the wire rod is rotating. The nozzles of multiple sets of nozzles 6 are all facing the axis of the turntable 7.

[0031] like Figure 3 As shown, the nozzle 6 is tilted in the direction of bar and wire conveying. The tilted nozzle 6 allows the coolant impacting the bar and wire to provide additional driving force, which is conducive to the stable conveying of the bar and wire. The tilt angle is 60°-75°. This angle design allows the coolant to impact the surface of the bar and wire in a way that is closer to the surface of the bar and wire, which is conducive to the coolant spreading and flowing quickly along the surface of the red steel, thereby forming a better coverage and continuous cooling effect.

[0032] like Figure 5 As shown, there are four sets of water supply pipes 5, which are evenly distributed around the axis of the annular water tank 3. By setting multiple sets of water supply pipes 5 in conjunction with the nozzles 6, the spraying frequency can be increased, which is beneficial to improving the cooling effect.

[0033] like Figure 5 As shown, support frames 8 are fixedly connected to both sides of the bottom of the housing 1. The support frames 8 are used to support the device. A drain outlet 10 is fixedly connected to the bottom of the housing 1. The drain outlet 10 is used to discharge wastewater from the housing 1.

[0034] like Figures 1 to 3As shown, the drive mechanism 9 includes a drive motor 91 and two sets of pulleys 92. The drive motor 91 is fixedly connected to a set of support frames 8 near the turntable 7. The two sets of pulleys 92 are fixedly connected to the drive motor 91 and the rotating shaft of the turntable 7, respectively. The two sets of pulleys 92 are connected by belt drive.

[0035] like Figure 5 As shown, multiple sets of reinforcing strips 11 are fixedly connected between the annular water tank 3 and the turntable 7. The multiple sets of reinforcing strips 11 are evenly distributed around the axis of the annular water tank 3. The multiple sets of reinforcing strips 11 are used to further enhance the structural strength of the device.

[0036] Working principle: The bar wire is passed through the turntable 7, the annular block 2 and the housing 1 in sequence. The water inlet pipe 4 is connected to the water supply pipe. During cooling, the drive motor 91 and two sets of pulleys 92 work together to drive the turntable 7 to rotate. The turntable 7 drives the water supply pipe 5 to rotate. The water supply pipe 5 drives the annular water tank 3 and multiple sets of nozzles 6 to rotate. The coolant passes through the water inlet pipe 4, water channel 2a, annular cavity, through hole 3a, annular water tank 3 and water supply pipe 5 in sequence and is then sprayed out from the multiple sets of nozzles 6 to impact the bar wire, thus cooling the bar wire. The multiple sets of nozzles 6 continuously rotate around the bar wire to achieve all-round cooling of the bar wire.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
