Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a cooling device for preventing cold shearing of steel bars at bends. Background Technology

[0002] In the traditional process of steel bar production, after the steel bars are rolled out, they are cooled slightly on a cooling bed and then sent to a fixed-length gantry shear via a conveyor roller to be cut into fixed lengths of different specifications. When the steel bars are cut in the fixed-length gantry shear, a bending phenomenon will occur. The countermeasures are generally to avoid steel bar stacking and replace the cold shear blades. However, the root cause of the bending is that when the steel temperature is high, its plasticity is very strong, and it is easy to deform under the action of shearing torque, thus leading to the formation of bending.

[0003] After the steel bars are rolled, they are placed on a cooling bed for air cooling. Due to space limitations, the temperature is generally reduced to 300℃~500℃ before cold shearing, so the steel bars need to be cooled. Patent publication number CN115608795A discloses a device and method for reducing the shearing bends of hot-rolled ribbed steel bars. The cooling method of this patent is to set up a water spray device before cold shearing to cool the cut end of the steel bar to 60℃-120℃. This method does prevent the formation of bends in the steel bars, but the water spray will leave moisture residue, resulting in the steel bar head being more prone to corrosion. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cooling device to prevent cold shearing of steel bars, which solves the technical problem in the prior art that using spray water to cool high-temperature steel bars results in water residue, making the steel bar heads more susceptible to corrosion.

[0016] Optionally, the middle part of the frame is a drain section, and the water tank is also located at the bottom of the drain section. The water tank is also used to receive the water flow below the drain section.

[0027] Optionally, the bottom of the frame has a lifting support for adjusting the height of the frame.

[0028] The beneficial effects of the embodiments of this utility model are as follows:

[0029] In this invention, when high-temperature steel bars are conveyed from the feed end to the conveyor chain, they pass under each air-cooling component in sequence as the chain moves. Temperature sensors located at different positions detect the temperature changes of the steel bars in real time and feed them back to the controller. Based on the temperature data at each detection point, the controller independently adjusts the output power of the corresponding air-cooling component: when the detected steel bar temperature is higher than the set range, the power of the corresponding air-cooling component is increased to enhance cooling; when the temperature is close to the target range, the power is reduced to avoid over-cooling. Through segmented cooling and dynamic power adjustment of multiple sets of air-cooling components, gradient cooling of the steel bars is achieved, ensuring that the temperature drops to the target range when it reaches the discharge end.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-3 As shown, this invention illustrates a cooling device for preventing cold shearing of reinforcing bars in one embodiment. The frame 1 of the cooling device has a long, narrow frame structure, with an inlet 101 for the reinforcing bars to enter at one end and an outlet 102 for the reinforcing bars to exit at the other end. A conveyor chain 2 is arranged in a closed loop around the frame 1 and rotates cyclically via a drive mechanism to carry the reinforcing bars to be cooled and convey them along the length of the frame 1. Multiple sets of air-cooling components 3 are spaced apart on the frame 1 from the inlet 101 to the outlet 102. Each set of air-cooling components 3 includes a support structure fixed to both sides of the frame 1, and a blowing device facing the conveyor chain 2 is installed on the support structure. The air outlet 301 is vertically or inclined toward the upper surface of the conveyor chain 2 to ensure that the blown airflow can cover the surface of the reinforcing bars. Temperature sensors 4 are fixed at preset intervals to the top or side of the frame 1, with their sensing ends facing the conveyor chain 2, for real-time acquisition of the surface temperature of the reinforcing bars. The controller 5 is located in the control box on one side of the rack 1. It is electrically connected to the temperature sensor 4 and the air-cooling component 3 via wires. It receives the temperature signal transmitted by the temperature sensor 4 and sends a power adjustment command to the air-cooling component 3 according to the preset temperature threshold and control logic.

[0046] For example, such as Figure 1As shown, when high-temperature steel bars are conveyed from the feed end 101 to the conveyor chain plate 2, they pass under each air-cooling component 3 in sequence as the chain plate moves. Temperature sensors 4 located at different positions detect the temperature changes of the steel bars in real time and feed them back to the controller 5. The controller 5 independently adjusts the output power of the corresponding air-cooling component 3 based on the temperature data of each detection point: when the detected steel bar temperature is higher than the set range, the power of the corresponding air-cooling component 3 is increased to enhance cooling; when the temperature is close to the target range, the power is reduced to avoid over-cooling. Through the segmented cooling and dynamic power adjustment of multiple sets of air-cooling components 3, the steel bars are cooled in a gradient manner, ensuring that their temperature drops to the target range when they reach the discharge end 102.

[0047] Multiple sets of air-cooling components 3 spaced apart on the frame 1 form segmented cooling zones, allowing the steel bars to cool gradually during transport. This avoids uneven cooling caused by excessive load on a single cooling unit, improving cooling efficiency and temperature control accuracy. The electrical connection between the temperature sensor 4 and the controller 5 enables real-time acquisition and processing of temperature signals. The controller 5 dynamically adjusts the power of the air-cooling components 3 based on the feedback signals, forming a closed-loop control circuit. This ensures that the steel bars receive matching cooling intensity at different cooling stages, avoiding both the risk of plastic deformation due to insufficient cooling and energy waste caused by over-cooling.

[0048] The air outlet 301 of the air-cooled component 3 is oriented towards the conveyor chain plate 2, allowing the airflow to directly act on the surface of the reinforcing bar. Forced convection heat transfer quickly removes heat, completely avoiding the problem of rust on the head of the reinforcing bar caused by residual moisture compared to existing spray cooling methods. It also eliminates the additional energy consumption of subsequent drying processes. The cyclical arrangement of the conveyor chain plate 2 enables continuous conveying of the reinforcing bar. Combined with the layout of multiple sets of air-cooled components 3, it forms a streamlined cooling operation, significantly improving the automation and continuity of the production process. The spaced arrangement of temperature sensors 4 ensures continuous monitoring of the reinforcing bar cooling process. The centralized control function of the controller 5 enables the cooling components to work collaboratively, effectively solving the rust defects caused by spray cooling in existing technologies. Simultaneously, precise temperature control reduces shear bending caused by excessively high steel temperatures.

[0049] Specifically, the air-cooling component can be divided into three groups to achieve multi-stage cooling. The first stage (500℃-400℃) is low-speed air cooling to avoid thermal stress; the second stage (400-250℃) is medium-speed air cooling; and the third stage (250-180℃) is high-speed air cooling to ensure that the temperature meets the standard before shearing.

[0050] In some examples, the mounting bracket 31 of the air-cooled assembly 3 is connected to the side wall of the frame 1 via a hinge shaft that extends horizontally, allowing the mounting bracket 31 to swing about the hinge shaft in a vertical plane. The frequency-modulated fan 32 is detachably mounted to the mounting surface of the mounting bracket 31 by bolts. When it is necessary to adjust the blowing angle, the limiting structure of the mounting bracket 31 is loosened, the mounting bracket 31 is manually rotated, causing the frequency-modulated fan 32 to swing, so that the air outlet 301 faces the desired angle. Then the limiting structure is fixed to complete the adjustment of the air outlet direction.

[0051] For example, such as Figure 2 As shown, the air-cooling component 3 can flexibly adjust the air outlet direction according to the specific placement of the reinforcing bars on the conveyor chain plate 2 and the size of reinforcing bars of different specifications. When conveying reinforcing bars of different diameters or shapes, the air outlet 301 can be adjusted to a more closely fitted angle to the surface of the reinforcing bars, enhancing the contact effect between the airflow and the surface of the reinforcing bars and improving cooling efficiency. At the same time, when it is necessary to strengthen the cooling of specific areas, the swing mounting bracket 31 can be used to target and cool the local area of ​​the reinforcing bars, avoiding the cooling blind spots caused by the fixed air outlet direction, making the cooling process more uniform and efficient.

[0052] In some examples, casters are installed at the four bottom corners of the frame 1 and the four bottom corners of the water tank 7. These casters are equipped with brakes to lock the device in place. The wheels 8 are made of wear-resistant rubber and can withstand the overall weight of the device. The wheel mounts are bolted to the bottom of the frame 1 and the water tank 7 for easy disassembly and replacement.

[0053] For example, such as Figure 1 As shown, when the cooling device needs to be moved, release the swivel wheel brakes and push the device to move it on the workshop floor. After reaching the designated position, lock the brake fixing device. The wheels 8 allow the device to move flexibly, adapting to production line layout adjustments or equipment maintenance needs, and can complete position changes without the need for lifting equipment.

[0054] In some examples, four lifting supports 9 are provided at the bottom of the frame 1. Each support includes a base, a hydraulic cylinder and a support column. The hydraulic cylinder is fixed on the base, the piston rod is connected to the support column, and the top of the support column is hinged to the bottom of the frame 1.

[0055] For example, such as Figure 1 As shown, when the height of frame 1 needs to be adjusted to match the height of upstream and downstream equipment (such as a cold shear machine), the hydraulic pump is started, and the piston rod of the hydraulic cylinder is extended and retracted through the control panel, driving the support column to rise and fall, thereby adjusting the overall height of frame 1. During the adjustment process, sensors monitor the height of each support in real time to avoid the problem of the conveyor chain plate 2 getting stuck due to inconsistent heights.

[0056] The lifting support 9 allows the cooling device to flexibly adapt to production line equipment of different heights, achieving seamless integration with upstream and downstream equipment and improving the overall coordination of the production line. The hydraulically driven lifting structure has the advantages of strong load-bearing capacity and high adjustment precision, ensuring the stability and reliability of the height adjustment of the frame 1 and meeting the installation requirements of different production environments.

[0057] Example 2

[0058] like Figures 4-7 As shown, this illustrates another embodiment of the present invention. The only difference between this embodiment and the first embodiment is that this embodiment not only uses the air-cooling component 3, but also adds a liquid-cooling component near the feed end 101. Through the liquid-cooling component and the air-cooling component 3, the steel bars can be cooled more quickly. Moreover, by installing the air-cooling component 3 at the discharge end 102, the water on the surface of the steel bars can be quickly dried to prevent the steel bars from rusting.

[0059] In some examples, the spray assembly 6 is set at the feed end 101 of the frame 1. The spray assembly 6 is fixed to both sides of the frame 1 by a bracket. The height of the bracket can be manually adjusted to accommodate steel bars of different diameters and the spray range can be adjusted.

[0060] For example, such as Figure 4 As shown, when the reinforcing bars enter the cooling device from the feed end 101, they first pass under the spray assembly 6. The controller 5 controls the solenoid valve to open based on the initial reinforcing bar temperature (e.g., 300-500℃) detected by the temperature sensor 4, and the spray assembly 6 sprays atomized water onto the surface of the reinforcing bars for initial cooling. The spraying time and water volume are automatically adjusted according to the initial temperature of the reinforcing bars and the conveying speed. After initial cooling, the reinforcing bars continue to move with the chain plate and enter the subsequent air-cooling assembly 3 for further cooling and drying.

[0061] A spray assembly 6 is installed at the feed end 101, which, together with the air-cooling assembly 3, forms a composite cooling method of "spray pre-cooling + air-cooling drying". The rapid heat exchange capacity of the spray water is used to initially cool the high-temperature steel bars, reducing the subsequent air-cooling load and improving the overall cooling efficiency. At the same time, the subsequent air-cooling assembly 3 can dry the residual moisture on the surface of the steel bars, avoiding the rust problem caused by traditional single spray cooling, thus balancing the cooling speed and rust prevention requirements.

[0062] In some examples, a rectangular water tank 7 is welded to the bottom of the frame 1. The top opening of the water tank 7 is aligned with the drainage holes at the bottom of the frame 1, and the drainage holes are evenly distributed below the conveyor chain plate 2. The water tank 7 is made of stainless steel with an anti-corrosion coating on the inner wall. It has a drain outlet and a filter screen at the bottom, and the drain outlet is connected to a wastewater treatment system via a pipe. The length of the water tank 7 is the same as the width of the bottom of the frame 1.

[0063] For example, such as Figure 7As shown, the water sprayed from the spray assembly 6 falls onto the surface of the reinforcing bars on the conveyor chain plate 2. Some of the water drips down with the movement of the reinforcing bars and falls into the water tank 7 below through the gaps in the chain plate and the drainage holes at the bottom of the frame 1. The filter screen inside the water tank 7 intercepts impurities in the water (such as steel oxide scale) to prevent clogging of the drainage pipes. Operators can periodically clean the filter screen and drain the wastewater from the water tank 7, achieving preliminary collection and treatment of water resources. The water tank 7 effectively receives the water sprayed from the spray assembly 6, preventing cooling water from splashing everywhere and polluting the production environment. At the same time, it facilitates centralized wastewater treatment, reducing water waste and environmental pollution.

[0064] In some examples, a drain section 103 is provided in the middle of the frame 1. It should be noted that this solution uses a conveyor chain plate 2 to transport the reinforcing bars. It is understood that the conveyor chain plate 2 has gaps, allowing water to fall into the water tank 7 below through the gaps. No spray assembly 6 is installed above the drain section 103, but guide plates can be installed on both sides to prevent water from splashing out. The water tank 7 is located at the bottom of the drain section 103 and is fixedly connected to the frame 1.

[0065] For example, such as Figure 4 and Figure 5 As shown, after the steel bars are pre-cooled by spraying, they enter the dewatering section 103. Residual moisture on their surface drips through the gaps in the chain plates under gravity, flowing into the water tanks 7 on both sides along the inclined surface at the bottom of the frame 1. The dewatering section 103 allows the steel bars to naturally drain before entering the subsequent air-cooling assembly 3, reducing water carryover and improving air-cooling drying efficiency. Simultaneously, the inclined bottom of the frame 1 and the guide plates ensure that water quickly converges into the water tanks 7, preventing water accumulation from affecting the chain plate operation.

[0066] In some examples, a set of dedicated air-cooling components 3 are set on the frame 1 near the discharge end 102. The air-cooling components 3 in this embodiment have the same structure as the air-cooling components 3 in embodiment one, but the air outlet 301 has a higher wind speed (rated wind speed 20m / s) and the wind direction is vertically downward and aimed at the surface of the conveyor chain plate 2 to ensure that there is enough air volume to dry the residual moisture on the surface of the steel bars.

[0067] For example, such as Figure 5 As shown, this completely solves the problem of wet steel bar surfaces caused by traditional spray cooling, effectively preventing corrosion caused by residual moisture.

[0068] In some examples, the spray assembly 6 includes a lifting seat 61, which is mounted on the frame 1; a main water outlet pipe 62 is mounted on the movable end of the lifting seat 61, and the main water outlet pipe 62 can move up and down with the movable end of the lifting seat 61; there are several spray pipes 63, one end of each spray pipe 63 is connected to the main water outlet pipe 62, the other end of each spray pipe 63 is located above the conveyor chain plate 2, and the outlet of each spray pipe 63 faces the conveyor chain plate 2.

[0069] For example, such as Figure 7 As shown, when cooling steel bars of different diameters is required, the operator can manually or via the control panel input the steel bar diameter parameters to drive the lifting seat 61 to raise and lower the main water outlet pipe 62 and the spray pipe 63, adjusting the distance between the nozzle and the steel bar surface to ensure that the spray covers the entire steel bar cross-section. The controller 5 synchronously adjusts the spray pressure and flow rate according to the steel bar diameter and conveying speed, so that the atomized water is evenly sprayed on the steel bar surface to achieve the best pre-cooling effect.

[0070] In some examples, the lifting seat 61 employs a screw 613 and nut transmission mechanism. The fixing sleeve 611 is vertically mounted on the side wall of the frame 1. The lifting housing 612 contains a nut that mates with the screw 613. The screw 613 is driven to rotate manually or by a servo motor to meet different height adjustment requirements. The main water outlet pipe 62 is fixed to the side of the lifting housing 612 via a flange and rises and falls synchronously with the housing.

[0071] For example, such as Figure 7 As shown, when the height of the spray assembly 6 needs to be adjusted, the servo motor drives the screw 613 to rotate, which in turn drives the lifting housing 612 to slide vertically within the fixed sleeve 611 via the nut, thereby adjusting the height of the main water outlet pipe 62 and the spray pipe 63. The height adjustment process can be operated manually or automatically controlled by the controller 5 according to the specifications of the reinforcing steel bars. The screw 613 transmission has a self-locking function to ensure that the spray assembly 6 is stably fixed after being raised or lowered, avoiding height changes due to vibration.

[0072] 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.
