Description

Technical Field

[0001] This invention relates to the field of hot coil box technology, and more specifically to a dual-station intelligent switching system for hot coil box rolling. Background Technology

[0002] The hot coil box is a key piece of equipment between the roughing and finishing mills in a hot continuous rolling production line. Its core function is to handle high-temperature strip steel at 1000-1200℃. It completes the strip steel transition process through a cycle of coiling and uncoiling. It typically employs a combination of coiling rollers and a rotating mechanism to achieve rapid coiling and uncoiling operations. Refer to the relevant patent CN116809637B. Essentially, it uses a fixed swing arm to stabilize the forming rollers and resist the impact of strip steel coiling. Simultaneously, a driving cylinder controls the forming plate to switch between oblique (fitting the coiled strip) and horizontal (avoiding empty strip) states, working in conjunction with free support rollers to ensure strip steel passage. The transition plate assembly is installed on the swing arm and reinforced with long keys and bolts, balancing maintenance convenience with structural stability.

[0003] To explain from the perspective of hot coil rolling: Traditional single-station hot coil rolling requires stopping the machine to switch between coiling and uncoiling states during operation, which interrupts the rolling process. The switching time is time-consuming and occupies effective working time. Moreover, the strip tension is prone to sudden changes and the temperature drops significantly during the switching process, which can easily cause deviation, wrinkling or oxidation and burning, affecting product quality. Therefore, it is necessary to transfer the strip to an additional uncoiling equipment after coiling is completed. By separating the uncoiling and coiling stations, the uncoiling operation can be avoided from occupying the coiling station, and the uncoiling and coiling operations can be carried out simultaneously, improving work efficiency. To this end, we provide a dual-station intelligent switching system for hot coil rolling to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent switching system for dual-station hot rolling in a hot coil box, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A dual-station intelligent switching system for hot coil rolling includes a base plate. The top surface of the base plate is provided with a dual-station processing unit that can perform coiling and uncoiling operations from two different directions. The interior of the dual-station processing unit is provided with a strip transfer unit that can drive the strip to rotate 180 degrees. The dual-station processing unit includes a protective shell fixedly installed on the top surface of the base plate, a support roller movably installed inside the protective shell for assisting the winding operation, and a main arm set inside the top surface of the protective shell for unwinding operation. The strip steel transfer unit includes a base fixedly connected to the middle of the top surface of the base plate, a bidirectional connecting rod rotatably connected inside the top surface of the base for connecting, and a partition plate fixedly connected to the side of the bidirectional connecting rod for winding the strip steel.

[0006] A further improvement of the technical solution of the present invention is that: a pressure roller bracket is movably connected to one side of the partition, an auxiliary pressure roller is rotatably connected inside the side of the pressure roller bracket, one end of the pressure roller bracket passes through the side of the partition and is fixedly connected to a connecting rod, one end of the connecting rod is movably connected to a telescopic rod, and one end of the telescopic rod is movably connected to the back of the partition.

[0007] A further improvement of the technical solution of the present invention is that: a limiting slide rod is fixedly connected to the bottom surface of the telescopic pressure plate, a gear disk is fixedly connected to the bottom surface of the partition, a winding roller is rotatably connected to the middle of the side surface of the partition, and a telescopic pressure plate is provided inside one end of the side surface of the partition.

[0008] A further improvement of the technical solution of the present invention is that: a power component is provided at one end of the back side of the partition, a drive wheel is fixedly connected to the output end of the power component, a follower gear is rotatably connected inside the partition, the follower gear meshes with the drive wheel, and one end of the take-up roller passes through the side of the partition and is fixedly connected to the side of the follower gear.

[0009] A further improvement of the technical solution of the present invention is that: a limiting track is provided inside the top surface of the base, the limiting slide rod is slidably connected inside the limiting track, a steering power component is provided inside one end of the top surface of the base, and an air outlet is fixedly connected to one end of the top surface of the base.

[0010] A further improvement of the technical solution of the present invention is that: a telescopic pressure plate is provided inside the side of the protective shell, a secondary arm is movably connected to one end of the main arm, an uncoiling knife is movably connected to the bottom surface of the secondary arm, and an auxiliary wheel is rotatably connected inside the side of one end of the uncoiling knife.

[0011] A further improvement of the technical solution of the present invention is that: a telescopic rod two is movably connected to the top surface of the main arm, one end of the telescopic rod two is movably connected to the inside of the side of the auxiliary arm, a telescopic rod three is movably connected to one end of the top surface of the auxiliary arm, and one end of the telescopic rod three is movably connected to the inside of the side of the uncoiling knife.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides a dual-station intelligent switching system for hot coil rolling. The system uses a power component to drive a drive wheel to rotate, which in turn drives a coiling roller to coil the strip steel through a meshing follower gear. During the coiling operation, a telescopic rod drives a connecting rod to keep the auxiliary pressure roller on the side of the pressure roller bracket in constant contact with the strip steel, ensuring coiling efficiency. At the same time, a telescopic pressure plate driven by a hydraulic rod and a component in the same position inside the dual-station processing unit restrict the deviation of the strip steel in the width direction, preventing interlayer misalignment of the steel coil during coiling and preventing the strip steel from deviating during uncoiling.

[0013] 2. This invention provides a dual-station intelligent switching system for hot coil rolling. After the coiling roller completes the coiling operation, the telescopic rod retracts, causing the pressure roller bracket to press tightly against the surface of the strip steel to prevent the strip steel from scattering during transfer. Subsequently, the steering power component drives the gear disk to rotate 180 degrees, further moving the strip steel on the surface of the coiling roller to another station. During the rotation, the limiting slide rod always slides inside the limiting track to avoid damage to the equipment due to excessive weight of the strip steel. When the equipment is working, the air outlet connected to the blower will blow air directly onto the surfaces of the power component, telescopic rod, and other structures to prevent them from malfunctioning due to high temperature.

[0014] 3. This invention provides a dual-station intelligent switching system for hot coil rolling. When the coiling operation is performed in the dual-station processing unit, the hydraulic system at the bottom of the support roller will push it out to assist in the coiling operation. At the same time, the telescopic pressure plate two and the telescopic pressure plate one will be adjusted to a suitable length to restrict the strip steel, ensuring the smooth progress of the strip steel coiling operation. After the winding operation is completed, the dual-station processing unit moves the winding roller with the strip steel on its surface to the inside of the protective shell with the main arm and other structures, and moves the idle winding roller to the winding station to continue the winding operation. At the same time, the main arm, the auxiliary arm and the uncoiler work together to complete the uncoiling operation of the strip steel, realizing the synchronous operation of winding and uncoiling, improving work efficiency and reducing resource consumption.

[0017] The present invention will be further described in detail below with reference to embodiments: Example 1: As Figure 1-7 As shown, the present invention provides a hot coil box dual-station intelligent switching system, including a base plate 1. The top surface of the base plate 1 is provided with a dual-station processing unit 2 that can complete coiling and uncoiling operations from two different directions respectively. The dual-station processing unit 2 is provided with a strip transfer unit 3 that can drive the strip to rotate 180 degrees. The strip transfer unit 3 includes a base 31 fixedly connected to the middle of the top surface of the base plate 1, a bidirectional connecting rod 32 rotatably connected to the inside of the top surface of the base 31 for connecting, and a partition plate 33 fixedly connected to the side of the bidirectional connecting rod 32 for coiling the strip. The bidirectional connecting rod 32 has two opposing partitions 33 on its left and right sides, which are respectively for processing operations of different directions and processes on both sides. The two partitions 33 are in opposite directions. A pressure roller bracket 36 is movably connected to one side of the partition 33. An auxiliary pressure roller 37 is rotatably connected inside the side of the pressure roller bracket 36. One end of the pressure roller bracket 36 passes through the side of the partition 33 and is fixedly connected to a connecting rod 34. One end of the connecting rod 34 is movably connected to a telescopic rod 35. One end of the telescopic rod 35 is movably connected to the back of the partition 33. The winding roller 312 provided on the side of the partition 33 can be used as the basis for winding the strip. The extension and retraction of the telescopic rod 35 can drive the connecting rod 34 to move, which in turn drives the pressure roller bracket 36 to move. The bottom curvature of the pressure roller bracket 36 is adapted to the curvature of the strip after winding. The auxiliary pressure roller 37 rotatably connected to the side of the pressure roller bracket 36 can assist in winding the strip. The telescopic pressure plate 310 is driven by a hydraulic push rod fixedly connected to the side of the partition 33. The telescopic pressure plate 310 will move along the axial direction of the partition 33. The power assembly 38 set on the back of the partition 33 is composed of a motor and a reducer, and can drive the follower gear 313 to rotate for transportation through the drive wheel 314.

[0018] In this embodiment, the drive wheel 314 is driven to rotate by the power component 38, and then the follower gear 313 meshing with it drives the coiling roller 312 to perform coiling operation on the strip. During the coiling operation, the telescopic rod 35 drives the connecting rod 34 to drive the auxiliary pressure roller 37 set on the side of the pressure roller bracket 36 to always be in contact with the strip, ensuring the coiling efficiency of the strip. At the same time, the telescopic pressure plate 310 driven by the hydraulic rod and the component in the same position inside the dual-station processing unit 2 will limit the deviation of the strip width direction, avoid the interlayer misalignment of the steel coil during coiling, and prevent the strip from running off-center when uncoiling.

[0019] Example 2: As Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a limiting slide rod 311 is fixedly connected to the bottom surface of the telescopic pressure plate 310, a gear disk 39 is fixedly connected to the bottom surface of the partition 33, a take-up roller 312 is rotatably connected to the middle of the side of the partition 33, the telescopic pressure plate 310 is provided inside one side of the partition 33, a power assembly 38 is provided at one back end of the partition 33, a drive wheel 314 is fixedly connected to the output end of the power assembly 38, a follower gear 313 is rotatably connected inside the partition 33, the follower gear 313 meshes with the drive wheel 314, and one end of the take-up roller 312 passes through the side of the partition 33 and is fixedly connected to the side of the follower gear 313. The overall shape of the bidirectional linkage 32 is T-shaped. Its bottom is connected to the gear disk 39 and the rotating rod is rotatably connected to the inside of the top surface of the base 31. The gear disk 39 rotates on the bottom surface inside the base 31 and meshes with the output end of the steering power assembly 316. The overall structure of the steering power assembly 316 is similar to that of the power assembly 38. A limiting track 315 is provided inside the top surface of the base 31, and a limiting slide rod 311 is slidably connected inside the limiting track 315. A steering power assembly 316 is provided inside one end of the top surface of the base 31, and an air outlet 317 is fixedly connected to one end of the top surface of the base 31. The interior of the limiting track 315 is a complete circular track, the size of which is adapted to the limiting slide bar 311, while ensuring that the limiting slide bar 311 can slide inside it. The air outlet 317 can be connected to an external blower, and its position corresponds to the position of the power component 38 on the back of the partition 33.

[0020] In this embodiment, after the take-up roller 312 completes the take-up operation, the telescopic rod 35 retracts, causing the pressure roller bracket 36 to press tightly against the strip surface to prevent the strip from scattering during transfer. Then, the steering power assembly 316 drives the gear disk 39 to rotate 180 degrees, further moving the strip on the surface of the take-up roller 312 to another station. During the rotation, the limiting slide rod 311 always slides inside the limiting track 315 to avoid damage to the equipment due to excessive weight of the strip. When the equipment is working, the air outlet 317 connected to the blower will blow the airflow directly onto the surfaces of the power assembly 38, telescopic rod 35, and other structures to prevent them from malfunctioning due to high temperature.

[0021] Example 3: As Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the dual-station processing unit 2 includes a protective shell 21 fixedly installed on the top surface of the base plate 1, a support roller 22 movably installed inside the protective shell 21 for assisting the winding operation, and a main arm 24 disposed inside the top surface of the protective shell 21 for unwinding operation. There are two protective shells 21, each facing a different direction. Their positions correspond to the positions of the two partitions 33. The second telescopic pressure plate 23 corresponds to the position of the first telescopic pressure plate 310 and is also driven by the hydraulic system. The second telescopic pressure plate 23 is stored inside the protective shell 21 and will not affect the normal rotation of the strip transfer unit 3. The width of the support roller 22 is slightly smaller than the width of the winding roller 312, and its bottom surface is provided with a hydraulic structure for driving. The protective shell 21 has a telescopic pressure plate 23 inside its side. One end of the main boom 24 is movably connected to a secondary boom 25. The bottom surface of the secondary boom 25 is movably connected to a coil cutter 26. One side end of the coil cutter 26 is rotatably connected to an auxiliary wheel 27. The top surface of the main boom 24 is movably connected to a telescopic rod 28. One end of the telescopic rod 28 is movably connected to the inside of the side of the secondary boom 25. One top end of the secondary boom 25 is movably connected to a telescopic rod 29. One end of the telescopic rod 29 is movably connected to the inside of the side of the coil cutter 26. The main boom 24 is driven by a motor for angle adjustment, and the movement of the auxiliary boom 25 and the uncoiler 26 is further controlled by the telescopic rod 28 and the telescopic rod 29. The uncoiler 26 is provided with auxiliary wheels 27 on its side so that it can adapt to the surface of the strip steel.

[0022] In this embodiment, when the winding operation is performed in the dual-station processing unit 2, the hydraulic system at the bottom of the support roller 22 will push it out to assist in the winding operation. At the same time, the telescopic pressure plate 23 and the telescopic pressure plate 310 will be adjusted to a suitable length to restrict the strip steel and ensure the smooth progress of the strip steel winding operation. After the winding operation is completed, the dual-station processing unit 2 will move the winding roller 312 with the strip steel on its surface to the inside of the protective shell 21 with the main arm 24 and other structures, and move the idle winding roller 312 to the winding station to continue the winding operation. At the same time, the cooperation of the main arm 24, the auxiliary arm 25 and the uncoiling knife 26 will complete the uncoiling operation of the strip steel, realizing the synchronous operation of winding and uncoiling, improving work efficiency and reducing resource consumption.

[0023] The working principle of this dual-station intelligent switching system for hot-rolling coils will be explained in detail below.

[0024] like Figure 1-7 As shown, the drive wheel 314 is driven to rotate by the power component 38, and then the winding roller 312 is driven to wind the strip steel by the follower gear 313 meshing with it. During the winding operation, the hydraulic system at the bottom of the support roller 22 will push it out to assist the winding operation. At the same time, the telescopic pressure plate 23 and the telescopic pressure plate 310 will be adjusted to a suitable length to restrict the strip steel and ensure the smooth progress of the strip steel winding operation. The telescopic rod 35 drives the connecting rod 34 to keep the auxiliary pressure roller 37 on the side of the pressure roller bracket 36 in contact with the strip steel, ensuring the strip steel winding efficiency. At the same time, the telescopic pressure plate 310 driven by the hydraulic rod and the component in the same position inside the dual-station processing unit 2 will limit the deviation of the strip steel in the width direction, avoid the steel coil from being misaligned between layers during winding, and prevent the strip steel from running off-center when uncoiling. After the take-up roller 312 completes the take-up operation, the telescopic rod 35 retracts and drives the pressure roller bracket 36 to press tightly against the surface of the strip steel to prevent the strip steel from scattering during transfer. Then, the turning power assembly 316 drives the gear disk 39 to rotate 180 degrees, further moving the strip steel on the surface of the take-up roller 312 to another station. During the rotation, the limiting slide rod 311 always slides inside the limiting track 315 to avoid damage to the equipment due to excessive weight of the strip steel. When the equipment is working, the air outlet 317 connected to the blower will blow the airflow directly onto the surface of the power assembly 38, telescopic rod 35 and other structures to prevent them from malfunctioning due to high temperature. After the winding operation is completed, the dual-station processing unit 2 will move the winding roller 312 with the strip steel on its surface to the inside of the protective shell 21 with the main arm 24 and other structures, and move the idle winding roller 312 to the winding station to continue the winding operation. At the same time, the cooperation of the main arm 24, the auxiliary arm 25 and the uncoiling knife 26 will complete the uncoiling operation of the strip steel, realizing the synchronous operation of winding and uncoiling, improving work efficiency and reducing resource consumption.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
