[0023] Reference Figure 1 to Figure 9, which is the first embodiment of the present invention, proposes a bar hot rolling cooling device for cooling a bar 1, comprising a frame 2, the frame 2 having a loading section 201 and a unloading section 202; a fixed shell 3 is arranged on the frame 2, located between the loading section 201 and the unloading section 202, the fixed shell 3 has a feed port 301 and a discharge port 302, the feed port 301 and the discharge port 302 are respectively connected to the loading section 201 and the unloading section 202; a rotating member 4 is rotatably arranged in the fixed shell 3, Coinciding with the axis of the fixed shell 3, the rotating member 4 has a plurality of accommodating portions 401, and the accommodating portions 401 and the inner wall of the fixed shell 3 form a plurality of cooling chambers 402; the cooling chambers 402 are used to accommodate the rods 1, and the side walls of the rods 1 are in frictional contact with the accommodating portions 401 and the inner wall of the fixed shell 3; after the rotating member 4 rotates, the plurality of cooling chambers 402 move synchronously, and the plurality of cooling chambers 402 are connected with or disconnected from the feed port 301 and the discharge port 302 in turn, so that the rods 1 entering the cooling chambers 402 rotate.

[0024] In this embodiment, in order to solve the problem of uneven cooling effect of hot-rolled bars in the related art, a bar hot-rolling cooling device is designed. The frame 2 is welded with high-strength steel and has sufficient rigidity and stability. The loading section 201 and the unloading section 202 are located at both ends of the frame 2. The fixed shell 3 is fixedly installed on the frame 2 by bolts, and is located between the loading section 201 and the unloading section 202. The feed port 301 and the discharge port 302 are respectively connected to the loading section 201 and the unloading section 202 to ensure that the bar 1 can enter and exit smoothly. The rotating member 4 is rotatably arranged in the fixed shell 3 through a bearing, and its axis coincides with the axis of the fixed shell 3. A number of accommodating portions 401 of specific shapes and sizes are evenly distributed on the rotating member 4, and each accommodating portion 401 is in the shape of an arc-shaped groove. When the rod 1 is placed in the cooling chamber 402, the side wall of the rod 1 is in close friction contact with the accommodating portion 401 and the inner wall of the fixed shell 3, ensuring that the rod 1 can rotate with the rotation of the rotating member 4 during the cooling process to achieve uniform cooling.

[0025] The advantage is that, through the unique structural design of the frame 2, the fixed shell 3 and the rotating part 4, the bar 1 can continuously rotate in the cooling chamber 402 during the cooling process, avoiding local overheating or overcooling, thereby effectively solving the problem of uneven cooling effect of the hot-rolled bar 1, improving the cooling efficiency, reducing product quality problems caused by uneven cooling, reducing the scrap rate, and thus reducing the waste of resources.

[0026] Furthermore, it also includes universal balls 5 , which are in a certain number and are arranged on the receiving portion 401 . The receiving portion 401 is in contact with the rod 1 through the universal balls 5 .

[0027] In this embodiment, a plurality of universal balls 5 are evenly installed at a certain interval on the inner surface of each receiving portion 401. These universal balls 5 are made of special materials that are resistant to high temperatures and wear, ensuring that they can rotate flexibly and will not fall off. When the rod 1 enters the cooling cavity 402, it first contacts these universal balls 5, which can automatically adjust their direction according to the shape and movement state of the rod 1, reduce the friction between the rod 1 and the receiving portion 401, and enable the rod 1 to enter the cooling cavity 402 more smoothly and rotate smoothly in the cooling cavity 402.

[0028] The advantage is that the provision of the universal ball 5 further reduces the friction resistance between the rod 1 and the accommodating portion 401, which is not only beneficial to the rotation of the rod 1 in the cooling chamber 402, making the cooling more uniform, but also reduces the heat and energy loss generated by friction, thereby extending the service life of the equipment, while also reducing damage to the surface of the rod 1, improving the surface quality of the product, further reducing the scrap rate, and reducing the waste of resources.

[0029] Furthermore, the accommodating portion 401 has a plurality of slide grooves 403, and the universal ball 5 is slidably arranged in the slide grooves 403. After the rod 1 enters the cooling chamber 402, it abuts against the plurality of universal ball 5, squeezing the universal ball 5 to slide into the slide grooves 403. It also includes an elastic member 6, which is arranged in the slide grooves 403. Both ends of the elastic member 6 act on the universal ball 5 and the accommodating portion 401 respectively, so as to provide a force for the universal ball 5 to slide into the cooling chamber 402.

[0030] In this embodiment, the arc surface of the receiving portion 401 is processed with a plurality of slide grooves 403 along its length direction, and the size of the slide grooves 403 matches the universal ball 5, ensuring that the universal ball 5 can slide stably in the slide grooves 403. The elastic member 6 is a high-strength spring, installed in the slide groove 403, one end of which is connected to the universal ball 5, and the other end is fixed to the inner wall of the receiving portion 401. When the rod 1 enters the cooling chamber 402, the rod 1 abuts against a plurality of universal balls 5, squeezing the universal balls 5 to slide into the slide groove 403, at which time the elastic member 6 is compressed and stores a certain amount of elastic potential energy. When the rod 1 leaves this position, the elastic member 6 releases the elastic potential energy, pushing the universal ball 5 back to the original position, and continues to prepare for the entry of the next rod 1.

[0031] The advantage is that the elastic member 6 is used in conjunction with the slide groove 403 and the universal ball 5, so that the universal ball 5 can always maintain close contact with the rod 1. This design can adapt to rods 1 of different diameters. At the same time, even if the rod 1 undergoes certain dimensional changes or position shifts during the cooling process, the elastic member 6 can be adaptively adjusted to ensure a good contact state between the rod 1 and the universal ball 5, thereby further improving the stability and uniformity of the rotation of the rod 1 in the cooling chamber 402, reducing the problem of uneven cooling caused by poor contact between the rod 1 and the accommodating portion 401, improving product quality, and reducing resource waste.

[0032] Furthermore, one end of the rotating member 4 extends out of the fixed shell 3 and has a ring gear 404, and also includes a transmission gear 7, which is rotatably set on the frame 2 and meshes with the ring gear 404; the driving member 8 is set on the frame 2, drives the transmission gear 7 to rotate, and drives the rotating member 4 to rotate.

[0033] In this embodiment, one end of the rotating member 4 extends out of the fixed housing 3, and a gear ring 404 is processed on the extended part to ensure the meshing accuracy and transmission efficiency of the gear ring 404 and the transmission gear 7. The transmission gear 7 is rotatably arranged on the frame 2 through a high-quality bearing, meshes well with the gear ring 404, and can smoothly transmit power. The driving member 8 uses a high-power stepping motor and is connected to the transmission gear 7 through a coupling and a chain. When the motor is started, the driving gear 7 is driven to rotate, thereby driving the rotating member 4 to rotate. After the motor rotates once, the switching between the cooling chambers 402 is realized. Assuming that there are four cooling chambers 402 in total, each rotation of the driving member 8 causes the rotating member 4 to rotate 90°, so that the cooling chamber 402 is accurately switched, and at the same time, it is ensured that the cooling chamber 402 can accurately overlap with the feed port 301, so that the rod 1 can smoothly enter the cooling chamber 402.

[0034] The advantage is that, through the precise coordination of the motor, the transmission gear 7 and the ring gear 404, a stable and reliable power source is provided for the rotating part 4, the rotation speed and accuracy of the rotating part 4 are guaranteed, so that the cooling chamber 402 can be connected or disconnected with the feed port 301 and the discharge port 302 in sequence according to a predetermined procedure, ensuring that the rotation and cooling process of the rod 1 in the cooling chamber 402 can be carried out in an orderly manner, thereby improving the degree of automation and production efficiency of the cooling device, while also ensuring the uniformity of the cooling effect and reducing resource waste.

[0035] Furthermore, the fixed shell 3 has a plurality of liquid inlets 303. After the cooling chamber 402 is disconnected from the feed port 301 and the discharge port 302, the cooling chamber 402 is connected to the liquid inlet 303, and the coolant enters the cooling chamber 402 through the liquid inlet 303. The rotating member 4 also has a through groove 405, and the accommodating portion 401 has a plurality of liquid discharge ports 406, and the plurality of liquid discharge ports 406 are all connected to the through groove 405.

[0036] In this embodiment, a plurality of liquid inlets 303 are evenly distributed on the fixed shell 3, and the liquid inlets 303 are connected to the external coolant circulation system through a pipeline, and a valve and a flow regulating valve are installed on the pipeline to control the amount and flow rate of the coolant entering. When the cooling chamber 402 is disconnected from the feed port 301 and the discharge port 302 as the rotating member 4 rotates, the cooling chamber 402 is connected to the liquid inlet 303 after the rotating member 4 rotates next time, and the coolant enters the cooling chamber 402 quickly and evenly through the liquid inlet 303, so as to efficiently cool the rod 1. A through groove 405 is designed at the center of the rotating member 4, and the through groove 405 is connected to a plurality of liquid discharge ports 406 on the accommodating portion 401. The position and size of the liquid discharge ports 406 are optimized to ensure that the coolant can be discharged smoothly.

[0037] The advantage is that the reasonable design of the liquid inlet 303 and the liquid outlet 406 and the effective connection with the coolant circulation system realize the efficient recycling of the coolant, can provide coolant in a timely and accurate manner according to the cooling needs of the rod 1, and ensure the stability and uniformity of the cooling effect.

[0038] Furthermore, it also includes a drain pipe 9, which is arranged on the frame 2 and located in the through groove 405, for closing a plurality of drain ports 406. The drain pipe 9 has a drain groove 901. After the rotating member 4 rotates, the drain groove 901 is connected with the drain port 406.

[0039] In this embodiment, the drain pipe 9 is made of corrosion-resistant metal material, installed on the frame 2, and located in the through slot 405 in the rotating frame. Its shape and size are closely matched with the through slot 405, and can effectively close a plurality of drain ports 406. A drain groove 901 is designed on the drain pipe 9. When the rotating member 4 rotates, the drain groove 901 can accurately communicate with the drain port 406 of one of the cooling chambers 402, and discharge the coolant in the cooling chamber 402 to an external collection device. The collection device filters, cools and recycles the coolant, thereby improving the utilization rate of the coolant.

[0040] The advantage is that the provision of the drain pipe 9 ensures the orderly discharge and collection of the coolant. Before the drain pipe 9 is added, the coolant can directly flow out from the drain port 406 after entering from the liquid inlet 303, and does not fully contact the rod 1. After the drain pipe 9 is added, the coolant in the cooling cavity 402 where the drain port 406 does not overlap with the drain groove 901 will not be discharged directly, but will remain in the cooling cavity 402, so that the rod 1 can fully contact with the coolant. As the rotating part 4 rotates, the drain port 406 of the cooling cavity 402 overlaps with the drain groove 901, and the coolant in the cooling cavity 402 can be discharged.

[0041] Furthermore, the feed port 301 and the discharge port 302 are both connected to the cooling chamber 402 that rotates to the top, and the drain groove 901 opens upward to discharge the coolant in the top cooling chamber 402.

[0042] In this embodiment, the feed port 301 and the discharge port 302 are both connected to the cooling chamber 402 that rotates to the top, and the drainage groove 901 opens upward and is aligned and connected to the drainage port 406 of the cooling chamber 402 that rotates to the top. After the rod 1 enters the top cooling chamber 402, as the rotating member 4 rotates and completes cooling, the cooled rod 1 is moved to the top again to be connected to the discharge port 302. When a new rod 1 enters the cooling chamber 402, the cooled rod 1 is pushed out of the cooling chamber 402. At the same time, the coolant in the top cooling chamber 402 is discharged into the collection device through the drainage groove 901 that opens upward under the action of gravity, realizing the simultaneous discharge of the rod 1 and the coolant, thereby improving production efficiency.

[0043] The advantage is that the special design of the feed port 301, the discharge port 302 and the drain tank 901 optimizes the cooling and discharge process of the bar 1, reduces production time and energy consumption, and improves production efficiency. At the same time, it ensures the effective discharge and collection of the coolant, further improves the utilization rate of the coolant, reduces resource waste, and also ensures the uniformity and stability of the cooling effect of the bar 1, thereby improving product quality.

[0044] Furthermore, the universal ball 5 is evenly arranged on the accommodating portion 401 , and the universal ball 5 includes a mounting seat 501 , which is slidably arranged in the slide groove 403 and connected to the elastic member 6 ; the abutment ball 502 is rotatably arranged in the mounting seat 501 .

[0045] In this embodiment, the mounting seat 501 of the universal ball 5 has good wear resistance and can slide smoothly in the slide groove 403. The abutment ball 502 is made of high-quality stainless steel material, and the surface is specially treated to have good wear resistance and corrosion resistance. The abutment ball 502 is rotatably arranged in the mounting seat 501 and can be flexibly rotated according to the movement state of the rod 1. The universal ball 5 is evenly arranged on the accommodating portion 401 to ensure that the rod 1 can be evenly supported, and at the same time, it has the function of reducing the friction between the rod 1 and the accommodating portion 401.

[0046] Furthermore, the through slot 405 is located at the center of the rotating member 4 and coincides with the axis of the rotating member 4 .

[0047] In this embodiment, the through groove 405 is located at the center of the rotating member 4 and coincides with the axis of the rotating member 4. The shape of the through groove 405 ensures good communication with the drain port 406 on the accommodating portion 401 without affecting the overall strength and rotation performance of the rotating member 4.

[0048] Furthermore, it also includes rollers 10 , and there are a plurality of rollers 10 . The rollers 10 are evenly rotated and arranged in the loading section 201 and the unloading section 202 . The middle section of the rollers 10 is concave and is used to transport the rods 1 .

[0049] In this embodiment, a plurality of rollers 10 are evenly rotated and arranged in the loading section 201 and the unloading section 202 through high-quality bearings. The middle section of the roller 10 is designed to be concave, and the curvature and depth of the concave are designed according to the size of the bar 1, which can stably support and transport the bar 1 and prevent the bar 1 from deflecting and sliding during the transportation process. Protective plates are installed at both ends of the roller 10 to prevent the bar 1 from accidentally falling during the transportation process.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
