Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, and more specifically, to a cooling mechanism for a cold rolling mill. Background Technology

[0002] A cold rolling mill is a new type of equipment for cold rolling steel bars. It is mainly used to process hot-rolled wire rods or round steel into cold-rolled ribbed steel bars of specific specifications at room temperature under pressure. Temperature control of the sheet material at the outlet of the cold rolling mill is a crucial factor in ensuring product quality. After rolling, metal sheets (especially thin sheets and strips) are typically maintained at a high temperature of 80-150℃ at the time of discharge. If the temperature is not cooled quickly and uniformly, the sheet material's performance will deteriorate, and oxidation on the surface will be accelerated.

[0003] In existing technologies, such as the cooling spray structure for a cold rolling mill disclosed in CN220195950U, the structure includes a base, on which the body of the cold rolling device is fixedly mounted. A support frame is also fixed to the top surface of the base, and a spray mechanism is mounted on the support frame. The spray mechanism includes two fixed frames, which are respectively fixed to the left and right sides of the inner top wall of the support frame. A drive motor is fixedly mounted on the back side of the inner wall of the left fixed frame, and a threaded rod is fixed to the output shaft of the drive motor. A movable block is threadedly connected to the center of the outer surface of the threaded rod. However, the nozzles in the above-mentioned cooling spray structure can only move the movable block back and forth via a connecting rod. Because the spray angle is fixed, uneven coverage and low cooling efficiency are easily caused. Utility Model Content

[0004] Therefore, in order to solve the problem of uneven coverage caused by a fixed spray angle, this utility model provides a cooling mechanism for a cold rolling mill, the specific technical solution of which is as follows:

[0005] A cooling mechanism for a cold rolling mill includes a processing table and a drying assembly. The processing table is equipped with a conveyor belt connected to the discharge end of the cold rolling mill. A processing housing is mounted on the conveyor belt. The processing housing includes a first cooling channel and a second cooling channel connected in sequence. Multiple adjustable nozzles are provided in the first cooling channel, and adjustable nozzles are movably connected to the adjustable nozzles. Multiple water curtain nozzles are provided in the second cooling channel. A recovery belt is also provided on the processing table. The drying assembly includes a hot air blower and a drying hood mounted on the recovery belt. The hot air blower is installed on the side wall of the drying hood, and the outlet of the hot air blower extends into the interior of the drying hood.

[0006] The aforementioned cold rolling mill cooling mechanism, equipped with a conveyor belt, facilitates the receiving and transfer of the sheet material exiting the cold rolling mill. The presence of a first and second cooling channel allows for rapid cooling to remove or reduce oxide scale on the sheet surface, improving surface quality and metal yield. This also helps reduce pickling time and acid consumption before secondary processing, lowering processing costs. The adjustable nozzles allow for changing the spray angle, enabling spraying in confined spaces without adjusting the entire nozzle angle, preventing uneven coverage. A recovery belt facilitates the recycling and retransfer of cooled sheet material. A drying assembly dries the sheet material on the recovery belt, removing moisture, preventing cracking and delamination, and improving the solderability of the pads.

[0007] Furthermore, the bottom of the processing table is provided with multiple displacement structures at intervals. Each displacement structure includes a mounting plate, a rotating seat, and displacement wheels. The mounting plate is fixed to the bottom of the processing table, the top of the rotating seat is rotatably mounted on the mounting plate, and the displacement wheels are installed on one side of the bottom of the rotating seat.

[0008] Furthermore, the conveyor belt is positioned below the recycling belt, and two drive structures are mounted on the processing table. The two drive structures are used to control the operating state of the conveyor belt and the operating state of the recycling belt, respectively.

[0009] Furthermore, several liquid storage tanks are provided on the side wall of the processing table, and each liquid storage tank is connected to a liquid extraction pipe. A valve is provided at one end of the liquid extraction pipe, and multiple first liquid outlet pipes are respectively connected to the other end of the liquid extraction pipe. The first liquid outlet pipes extend into the interior of the first cooling channel, and multiple nozzles are opened on the first liquid outlet pipes. Each nozzle is equipped with an adjusting nozzle.

[0010] Furthermore, the adjustable nozzle includes a fixed head, a nozzle body, and an adjusting ball. One end of the fixed head is threaded onto the nozzle. A movable cavity is provided inside the nozzle body. The adjusting ball is adapted to the movable cavity and rotatably inserted into the movable cavity. The top of the adjusting ball is connected to the other end of the fixed head. A connecting pipe is provided at the bottom of the adjusting ball. The connecting pipe extends and connects to the interior of the adjustable nozzle.

[0011] Furthermore, the adjusting nozzle also includes a locking structure, which includes a threaded rod, a rotating handle, and a locking pad. The threaded rod is threaded into the side wall of the nozzle body, and a rotating handle is detachably fitted onto one end of the threaded rod. The other end of the threaded rod extends into the movable cavity and is fixedly connected to the locking pad.

[0012] Furthermore, a limiting groove is formed on one end of the locking pad near the adjusting ball, and a plurality of extrusion blocks are uniformly protruded on the outer surface of the adjusting ball, the extrusion blocks being adapted to the limiting groove.

[0013] Furthermore, multiple second liquid outlet pipes are inserted into the second cooling channel, and multiple water curtain nozzles are spaced apart on each second liquid outlet pipe. Each water curtain nozzle is equipped with a water curtain nozzle, and the outlet of the water curtain nozzle is elongated. A water curtain space is formed between the water curtain nozzle on each second liquid outlet pipe and the recycling belt for the plate to pass through.

[0014] Furthermore, the drying assembly also includes a feeding hood and a discharging hood connected to both ends of the drying hood. Both the feeding hood and the discharging hood are threadedly fixed to the processing table. A sealing plate is hinged to the feeding end of the feeding hood and the discharging end of the discharging hood.

[0015] Furthermore, a drying chamber is formed inside the drying hood, and a guide air box is provided at the top of the drying chamber. The air outlet of the hot air blower extends into the drying chamber through a connecting hose and communicates with the guide air box. The connecting hose is detachably fixed to the top of the drying hood. Attached Figure Description

[0026] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0027] like Figure 1 , Figure 2 and Figure 5As shown, a cooling mechanism for a cold rolling mill in one embodiment of the present invention includes a processing table 1 and a drying assembly 7. The processing table 1 is provided with a conveyor belt 2 connected to the discharge end of the cold rolling mill. A processing housing 3 is provided on the conveyor belt 2. The processing housing 3 includes a first cooling channel 31 and a second cooling channel 32 connected in sequence. The first cooling channel 31 is provided with a plurality of adjustable nozzles 4, and adjustable nozzles 41 are movably connected to the adjustable nozzles 4. The second cooling channel 32 is provided with a plurality of water curtain nozzles 5. A recovery belt 6 is also provided on the processing table 1. The drying assembly 7 includes a hot air blower 71 and a drying hood 72 covered on the recovery belt 6. The hot air blower 71 is installed on the side wall of the drying hood 72, and the air outlet of the hot air blower 71 extends into the interior of the drying hood 72.

[0028] The aforementioned cold rolling mill cooling mechanism includes a conveyor belt 2 for receiving and transferring the sheet material from the cold rolling mill; a first cooling channel 31 and a second cooling channel 32 for rapidly removing or reducing oxide scale on the sheet surface, improving surface quality and metal yield, reducing pickling time and acid consumption before secondary processing, and lowering processing costs; an adjustable nozzle 41 for changing the spray angle, allowing for spraying in different directions without adjusting the entire nozzle 4 in confined spaces, thus avoiding uneven coverage; a recovery belt 6 for recycling and retransferring the cooled sheet material; and a drying assembly 7 for drying the sheet material on the recovery belt 6, removing moisture, preventing cracking and delamination, and improving solderability of the pads.

[0029] like Figure 1 As shown, in one embodiment, a plurality of displacement structures 8 are spaced apart at the bottom of the processing table 1. The displacement structure 8 includes a mounting plate, a rotating seat and a displacement wheel. The mounting plate is fixed to the bottom of the processing table 1, the top of the rotating seat is rotatably mounted on the mounting plate, and the displacement wheel is installed on one side of the bottom of the rotating seat.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the conveyor belt 2 is positioned below the recovery belt 6, and two drive structures 9 are mounted on the processing table 1. The two drive structures 9 are used to control the operating states of the conveyor belt 2 and the recovery belt 6, respectively. The drive configuration for controlling the conveyor belt 2 and the recovery belt 6 is prior art, and the specific technical features and installation method of the drive structures 9 will not be described in detail here.

[0031] like Figure 1 and Figure 2As shown, in one embodiment, a plurality of liquid storage tanks 11 are provided on the side wall of the processing table 1. Each liquid storage tank 11 is connected to a liquid extraction pipe 12. One end of the liquid extraction pipe is provided with a valve, and the other end of the liquid extraction pipe 12 is respectively connected to a plurality of first liquid outlet pipes 311. The first liquid outlet pipes 311 extend into the interior of the first cooling channel 31, and a plurality of nozzles are opened on the first liquid outlet pipes 311. Each nozzle is equipped with an adjusting nozzle 4. The liquid storage tanks 11 are used to store coolant or other forms of flowable cooling medium. The valves on the liquid storage tanks 11 are used to change the cross-section of the passage and the direction of medium flow, and have functions such as guiding, stopping, throttling, checking, diverting or overflowing pressure relief. The specific details are prior art and will not be described in detail.

[0032] like Figures 2-4 As shown, in one embodiment, the adjustable nozzle 4 includes a fixed head 42, a nozzle body 43, and an adjusting ball 44. One end of the fixed head 42 is threaded onto the nozzle. A movable cavity 431 is formed inside the nozzle body 43. The adjusting ball 44 is adapted to the movable cavity 431 and rotatably inserted into the movable cavity 431. The top of the adjusting ball 44 is connected to the other end of the fixed head 42, and a connecting pipe 45 is provided at the bottom of the adjusting ball 44. The connecting pipe 45 extends and connects to the inside of the adjusting nozzle 41. The adjusting ball 44 can be adjusted at any angle inside the movable cavity 431, thereby changing the angle of the adjusting nozzle 41. In the confined space, this allows for more uniform liquid spraying and better cooling.

[0033] Furthermore, the adjusting ball 44 is hollow, ensuring that the interiors of the fixed head 42, adjusting ball 44, connecting pipe 45, and adjusting nozzle 41 are all interconnected.

[0034] Specifically, the connecting pipe 45 is a flexible hose. The flexible hose is preferably made of a stretchable material (such as rubber, plastic, metal, etc.). The flexibility of the hose allows it to adapt to complex pipe layouts and space constraints, making it particularly convenient for operation in narrow spaces. When the nozzle body 43 rotates, the hose can adjust its length and direction by adjusting the angle of the nozzle 4.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment, the adjusting nozzle 4 further includes a locking structure, which includes a threaded rod 46, a handle 47, and a locking pad 48. The threaded rod 46 is threaded into the side wall of the nozzle body 43. The handle 47 is detachably fitted onto one end of the threaded rod 46, and the other end of the threaded rod 46 extends into the movable cavity 431 and is fixedly connected to the locking pad 48. By providing the handle 47, the operator can use the handle 47 to control the rotation state of the threaded rod 46, thereby adjusting the abutment relationship between the locking pad 48 and the adjusting ball 44, thus restricting the movement of the adjusting ball 44 and completing the angle locking of the adjusting nozzle 4.

[0036] Preferably, the locking pad 48 is a rubber anti-slip pad. By increasing the coefficient of friction, the sliding between the adjusting ball 44 and the locking pad 48 is reduced, thereby effectively limiting the rotation state of the adjusting ball 44.

[0037] like Figure 4 As shown, in one embodiment, a limiting groove is formed on the end of the locking pad 48 near the adjusting ball 44, and a plurality of pressing blocks 441 are uniformly protruded on the outer surface of the adjusting ball 44, the pressing blocks 441 being adapted to the limiting groove. Through the cooperative use of the locking pad 48 and the pressing blocks 441, the adjusting ball 44 and the nozzle body 43 can be fixed after the angle is adjusted. The locking pad 48 and the pressing blocks 441 are pressed against each other, causing the locking pad 48 to deform and thus fit more closely to the pressing blocks 441, resulting in a better fixing effect between the nozzle body 43 and the adjusting ball 44.

[0038] like Figure 2 As shown, in one embodiment, a plurality of second liquid outlet pipes 321 are inserted into the second cooling channel 32. Each second liquid outlet pipe 321 is provided with a plurality of water curtain nozzles 5 at intervals. The water curtain nozzles 5 are equipped with water curtain nozzles, and the outlets of the water curtain nozzles are arranged in an elongated shape. A water curtain space is formed between the water curtain nozzles on each second liquid outlet pipe 321 and the recovery belt 6 for the plate to pass through. By densely spraying water from multiple water curtain nozzles, a water film is formed on the surface of the plate, further controlling the temperature of the plate and improving the cooling efficiency.

[0039] Specifically, the multiple water curtain nozzles on the same second outlet pipe 321 are arranged in parallel.

[0040] like Figure 5 As shown, in one embodiment, the drying assembly 7 further includes an inlet hood 73 and an outlet hood 74 connected to both ends of the drying hood 72. Both the inlet hood 73 and the outlet hood 74 are threadedly fixed to the processing table 1. A sealing plate 75 is hinged to both the inlet end of the inlet hood 73 and the outlet end of the outlet hood 74. The sealing plates 75 at both ends prevent cold air from entering the drying hood 72, thereby maintaining the temperature of the hot airflow and avoiding a reduction in thermal efficiency due to cold air mixing. Furthermore, the sealed state ensures sufficient contact between the hot airflow and the sheet material for adequate heat exchange, improving drying efficiency.

[0041] like Figure 5As shown, in one embodiment, a drying chamber is formed inside the drying hood 72. A guide air box 721 is provided at the top of the drying chamber. The air outlet of the hot air blower 71 extends into the drying chamber through a connecting hose 711 and communicates with the guide air box 721. The connecting hose 711 is detachably fixed to the top of the drying hood 72. The guide air box 721 ensures that the airflow of the hot air blower 71 is distributed to the bottom area of ​​the drying chamber, thereby reducing heat loss and effectively improving drying efficiency.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
