Description

Technical Field

[0001] This utility model relates to the field of controlled cooling equipment technology, and in particular to a positioning mechanism and a nozzle base. Background Technology

[0002] Controlled rolling and cooling systems are essential components of modern bar production lines. Their mechanism involves online water spray cooling of the steel, followed by tempering using its residual heat, and then final rolling at the required temperature to ensure its mechanical properties. A controlled rolling and cooling system generally consists of a water tank and a nozzle base, with cooling water flowing between them via a circular interface. Each time a steel rolling mill changes specifications, the cooling nozzle base needs to be replaced. Replacement is typically done by hoisting the nozzle base from the mill and aligning it with the interface on the water tank. However, precise alignment of the circular interface is difficult, requiring constant fine-tuning on-site and relying on experience. This often results in misalignment, reducing the efficiency of nozzle base installation. Furthermore, misalignment can lead to water leakage, causing uneven cooling of the rolled steel. There is also the risk of base displacement and process malfunctions. Therefore, we propose a positioning mechanism and nozzle base. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the technical problem of difficulty in aligning the nozzle base with the water tank in the prior art, this utility model is proposed.

[0005] The purpose of this invention is to provide a positioning mechanism that solves the problem of low installation efficiency between the nozzle base and the water tank.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a positioning mechanism, which includes a cooling control component, including a nozzle base and a cooling water tank, wherein the nozzle base is located on the upper part of the cooling water tank, the cooling water tank is provided with a water tank interface communicating with the inner cavity on the side near the nozzle base, and the nozzle base is provided with a nozzle interface cooperating with the water tank interface on the side near the cooling water tank.

[0007] The positioning component includes positioning block one and positioning block two, which are disposed on the cooling water tank and located around the water tank interface, and a positioning interval is constructed between positioning block one and positioning block two for the nozzle interface to engage.

[0008] In a preferred embodiment of the positioning mechanism of this utility model, both positioning block one and positioning block two are made of nuts and are fixed to the cooling water tank by welding.

[0009] In a preferred embodiment of the positioning mechanism of this utility model, the number of positioning block one and positioning block two are three and one, respectively.

[0010] As a preferred embodiment of the positioning mechanism of this utility model, the cooling water tank is provided with a connecting pipe communicating with the inner cavity on one side, and a connecting flange is provided at one end of the connecting pipe.

[0011] As a preferred embodiment of the positioning mechanism of this utility model, a sealing component for preventing cooling water leakage is provided between the nozzle interface and the water tank interface. The sealing component includes a sealing groove formed around the water tank interface, and a sealing ring that fits into the nozzle interface is provided in the sealing groove.

[0012] As a preferred embodiment of the positioning mechanism of this utility model, the cooling water tank is provided with a fixing component for improving the installation stability between the cooling water tank and the nozzle base. The fixing component includes a fixing plate fixedly installed on both sides of the nozzle interface. The cooling water tank is provided with a fixing pad that contacts the fixing plate. The fixing pad is provided with a fixing block that abuts against the fixing plate.

[0013] In a preferred embodiment of the positioning mechanism of this utility model, the contact end between the fixing block and the fixing plate is inclined.

[0014] The beneficial effects of the positioning mechanism of this utility model are as follows: by setting positioning block one and positioning block two, a positioning range is constructed at the water tank interface. When the nozzle interface descends, it will fall directly into the positioning range. Furthermore, under the obstruction of positioning block one and positioning block two, the nozzle interface is not prone to displacement, thereby ensuring the positioning quality and improving the assembly efficiency between the nozzle base and the cooling water tank. At the same time, the special setting of positioning block two increases the contact area between positioning block two and the nozzle interface, thereby improving the installation stability between the nozzle base and the cooling water tank.

[0015] Another objective of this invention is to provide a nozzle base that reduces frictional losses when the vehicle is connected to the nozzle base.

[0017] In a preferred embodiment of the nozzle base of this utility model, the edge of the lifting hole is designed as a smooth curved surface.

[0018] The beneficial effects of the nozzle base of this utility model are as follows: the setting of the lifting protrusion and the lifting hole facilitates the connection between the nozzle base and the trolley, making it convenient for the nozzle base to be raised, lowered and moved. In addition, the setting at the edge of the lifting hole can reduce the wear when the trolley and the nozzle base are connected, thereby extending the service life of the corresponding workpiece.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] 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.

[0027] 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.

[0028] Example 1, referring to Figures 1-4This is the first embodiment of the present invention. This embodiment provides a positioning mechanism, including a controlled cooling assembly 100, comprising a nozzle base 101 and a cooling water tank 102. The nozzle base 101 is located on the upper part of the cooling water tank 102. The cooling water tank 102 has a water tank interface 105 communicating with the inner cavity on the side near the nozzle base 101, and a nozzle interface 103 cooperating with the water tank interface 105 on the side near the cooling water tank 102. Controlled rolling and controlled cooling technology is an important process in modern steel rolling production used to improve the performance of steel. It improves the strength, toughness and weldability of steel by controlling process parameters such as heating temperature, rolling process and cooling conditions during rolling. In this embodiment, the cooling water in the cooling water tank 102 is introduced into the nozzle base 101 through the connection of the water tank interface 105 and the nozzle interface 103, thereby controlling the cooling operation and improving the performance of the steel.

[0029] The positioning component 200 includes a positioning block 1 201 and a positioning block 202 disposed on the cooling water tank 102 and located around the water tank interface 105, and a positioning interval is constructed between the positioning block 1 201 and the positioning block 202 for engaging the nozzle interface 103. During actual installation of the nozzle interface 103 and the water tank interface 105, the operator needs to stand on the platform and repeatedly direct the crane to lift the nozzle base 101 and the nozzle interface 103 on it. Because the alignment between the nozzle interface 103 and the water tank interface 105 is difficult, it is necessary to make continuous fine adjustments on site, and the adjustment can only be made by experience. This makes the work efficiency extremely low. Replacing 6 sections of nozzle base 101 often takes about 45 minutes. Therefore, in this embodiment, positioning block 1 201 and positioning block 2 202 are provided around the water tank interface 105. A positioning interval is constructed between positioning block 1 201 and positioning block 2 202. When the nozzle interface 103 is lowered, it will fall directly into the positioning interval. Under the obstruction of positioning block 1 201 and positioning block 2 202, the nozzle interface 103 is not easy to deviate, thereby ensuring the positioning quality and improving the assembly efficiency between the nozzle base 101 and the cooling water tank 102.

[0030] Furthermore, both positioning block 1 201 and positioning block 2 202 are made of nuts and are fixed to the cooling water tank 102 by welding. Because both positioning block 1 201 and positioning block 2 202 are made of nuts of the same size, the difficulty of obtaining positioning block 1 201 and positioning block 202 is reduced, thereby reducing the manufacturing cost of positioning component 200, which is conducive to the promotion of equipment and the replacement of its internal components.

[0031] Furthermore, the number of positioning blocks 1 (201) and 2 (202) are three and one, respectively. For example... Figure 3As shown, due to space constraints, the number of positioning blocks 1 201 and positioning blocks 2 202 are three and one respectively. Positioning block 2 202 is positioned directly opposite the water tank interface 105, thereby increasing the contact area between positioning block 2 202 and nozzle interface 103 and improving the installation stability between nozzle base 101 and cooling water tank 102.

[0032] Furthermore, a connecting pipe 104 communicating with the inner cavity is provided on one side of the cooling water tank 102, and a connecting flange is provided at one end of the connecting pipe 104. The connection pipe 104 and the connecting flange facilitate the connection of the cooling water tank 102 with other controlled cooling equipment, allowing the cooling water inside to flow freely and ensuring the normal operation of the controlled cooling process.

[0033] In use, a positioning range is constructed at the water tank interface 105 by setting positioning block 1 201 and positioning block 2 202. When the nozzle interface 103 descends, it will fall directly into the positioning range. Under the obstruction of positioning block 1 201 and positioning block 2 202, the nozzle interface 103 is not easy to deviate, thus ensuring the positioning quality and improving the assembly efficiency between the nozzle base 101 and the cooling water tank 102. At the same time, the special setting of positioning block 2 202 increases the contact area between positioning block 2 202 and nozzle interface 103, improving the installation stability between nozzle base 101 and cooling water tank 102.

[0034] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, it further includes a sealing component 300 between the nozzle interface 103 and the water tank interface 105 to prevent cooling water leakage. The sealing component 300 includes a sealing groove 301 formed around the water tank interface 105, and a sealing ring 302 that fits snugly against the nozzle interface 103 is provided in the sealing groove 301. The sealing ring 302 is made of rubber and has a certain degree of resilience. When the nozzle interface 103 is pressed against it under its own weight, the sealing ring 302 is first compressed, and then, under its own properties, begins to rebound, thus tightly fitting against the nozzle interface 103. This reduces the assembly gap between the nozzle interface 103 and the water tank interface 105, preventing cooling water leakage.

[0035] Furthermore, the cooling water tank 102 is provided with a fixing component 400 to improve the installation stability between the cooling water tank 102 and the nozzle base 101. The fixing component 400 includes a fixing plate 401 fixedly installed on both sides of the nozzle interface 103, a fixing pad 402 on the cooling water tank 102 that contacts the fixing plate 401, and a fixing block 403 on the fixing pad 402 that abuts against the fixing plate 401. Figure 3As shown, when the nozzle base 101 and the cooling water tank 102 are assembled together, one end of the fixing plate 401 on both sides of the nozzle interface 103 will abut against the fixing block 403 respectively, thereby fixing the nozzle base 101 and greatly achieving the function of the nozzle base 101 moving laterally.

[0036] Furthermore, the contact end between the fixing block 403 and the fixing plate 401 is inclined. The inclined arrangement of the contact end between the fixing block 403 and the fixing plate 401 facilitates the contact between the fixing plate 401 of different sizes and the fixing block 403, thereby improving the versatility and flexibility of assembly with the cooling water tank 102. Moreover, it eliminates the need to design and manufacture corresponding fixing blocks 403 separately for each size of fixing plate 401, thereby reducing production costs and maintenance difficulty.

[0037] In use, the combination of the self-rebound performance of the sealing groove 301 and the sealing ring 302 can reduce the assembly gap between the nozzle interface 103 and the water tank interface 105, thus avoiding the leakage of cooling water. At the same time, the inclined setting of the contact end between the fixing block 403 and the fixing plate 401 makes it easier for fixing plates 401 of different sizes to abut against the fixing block 403, thereby improving the versatility and flexibility of assembly with the cooling water tank 102.

[0038] Example 3, referring to Figure 5 This is the third embodiment of the present invention, which further provides a nozzle base. It includes an auxiliary component 500, comprising a lifting protrusion 501 disposed on the nozzle base 101, and a lifting hole 502 on the lifting protrusion 501. Because the nozzle base 101 in the controlled rolling and cooling device is relatively large and heavy, during the actual installation of the nozzle interface 103 and the water tank interface 105, the operator needs to stand on the platform and repeatedly direct the crane to raise and lower the nozzle base 101 and its nozzle interface 103. The lifting protrusion 501 and lifting hole 502 provided in this embodiment facilitate the connection between the nozzle base 101 and the crane, thereby facilitating the raising, lowering, and moving of the nozzle base 101.

[0039] Furthermore, the edge of the lifting hole 502 is designed as a smooth curved surface. A smoother surface treatment can reduce surface friction and wear on the workpiece, because rough surfaces tend to have more surface irregularities or small protrusions, leading to increased friction and wear when the workpiece moves on other surfaces, thus improving corrosion resistance. Smooth surfaces have less exposed surface area, making corrosion less likely. Rough surfaces tend to have more surface area exposed to the environment, which may increase the possibility of corrosion. Therefore, the smooth curved surface provided at the edge of the lifting hole 502 in this embodiment can reduce wear when the trolley engages with the nozzle base 101, thereby extending the service life of the corresponding workpiece.

[0040] In use, the lifting protrusion 501 and the lifting hole 502 facilitate the connection between the nozzle base 101 and the trolley, making it easy to lift and move the nozzle base 101. In addition, the setting at the edge of the lifting hole 502 can reduce the wear when the trolley is connected to the nozzle base 101, thereby extending the service life of the corresponding workpiece.
