Description

Technical Field

[0001] This invention relates to the field of hot rolling equipment technology, specifically to a hot rolling forming equipment for interlayer strengthening composite metal sheet and strip. Background Technology

[0002] Interlayer strengthening hot rolling of metal sheets is an advanced manufacturing technology that introduces a strengthening mechanism between the layers of metal sheets through hot rolling, thereby producing novel metal layered composite sheets with higher mechanical properties (such as strength and stiffness) or specific functions. Simply put, it uses the key processing step of "hot rolling" to "weld" multiple layers of metal sheets together, forming a "reinforced" structure between the layers, ultimately "forming" a single sheet with superior performance. Interlayer strengthening hot rolling technology achieves metallurgical bonding of dissimilar metal layers through atomic diffusion under high temperature and pressure, and is the core process for preparing high-performance layered composite sheets.

[0003] However, in the hot rolling process of layered composite plates, the cleanliness of the interface is a key factor determining the interlayer strengthening effect. In existing technologies, although a descaling process is included before rolling, for multi-layer stacked composite processes, a dense oxide film rapidly forms on the surface of the metal layers during high-temperature heating. These oxide films (iron oxide scale) are difficult to completely break down and remove during hot rolling deformation, and are easily pressed into the metal matrix or retained at the interlayer bonding interface.

[0004] This not only causes surface defects, but more seriously hinders the diffusion and bonding of interlayer atoms, leading to a decrease in interlayer bonding strength, delamination or inclusions, and significantly weakening the mechanical properties and strengthening effect of layered composite plates. Therefore, how to effectively prevent or remove oxide scale from being pressed in during the hot rolling process is a technical problem that urgently needs to be solved to improve the quality of interlayer strengthening hot rolling. Summary of the Invention

[0005] The purpose of this invention is to provide a metal sheet and strip interlayer reinforced composite hot rolling forming equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal sheet and strip interlayer reinforced composite hot rolling forming equipment, including a machine base, a roll support mounted on the machine base, two hot rolling rolls mounted on the roll support, a flushing chamber provided on the input end side of the hot rolling rolls, and an inlet, a flushing chamber and an outlet provided on the flushing chamber, the inlet and the outlet being connected to the flushing chamber;

[0007] The flushing chamber is equipped with an elastic plate that can change the flow pressure of the flushing water. The flushing chamber is equipped with a drive assembly for driving the elastic plate to move. The flushing chamber is slidably connected to a connecting rod. The connecting rod is equipped with a push assembly that pushes the elastic plate to deform as it rotates.

[0008] The connecting rod is provided with a rolling part, and an elastic element is provided between the flushing chamber and the hot rolling roll to provide a pressing force on the flushing chamber toward the hot rolling roll.

[0009] Furthermore, the hot rolling rolls are provided in two and are installed on the roll support from top to bottom. A drive motor is installed at one end of the machine base, and the drive motor is connected to the two hot rolling rolls through a transmission box.

[0010] A fixing plate is installed on the top of the roll support, and an adjusting screw for adjusting the vertical position of the upper hot roll is threaded through the fixing plate.

[0011] Furthermore, the roll support is provided with a mounting bracket, the connecting rod passes through the fixing sleeve on the mounting bracket, one end of the connecting rod is rotatably connected to the connecting plate, and the flushing chamber is installed on the connecting plate;

[0012] The flushing chamber has a receiving cavity on the side facing the connecting plate. The flushing cavity is connected to the receiving cavity. The elastic plate is located in the receiving cavity and separates the receiving cavity from the flushing cavity.

[0013] Furthermore, the length direction of the flushing chamber is parallel to the width direction of the metal sheet to be hot-rolled, and the inlet and outlet are respectively opened on the two side walls of the flushing chamber along the length direction.

[0014] A turbulence chamber is provided at one end of the flushing chamber near the water outlet. The turbulence chamber is connected to the flushing chamber and the water outlet, and the longitudinal height of the inner wall of the turbulence chamber decreases sequentially towards the water outlet.

[0015] Furthermore, the surface of the elastic plate has multiple trough sections that bulge and extend toward the flushing chamber, and sliding parts are fixed to both ends of the elastic plate along its length. The sliding parts are engaged in the receiving cavity and can slide along the length of the flushing chamber.

[0016] An extension arm is fixedly attached to the elastic plate. The extension arm passes through the connecting plate and the mounting bracket in sequence. The driving assembly includes a cylinder mounted on the mounting bracket. The cylinder rod is connected to the extension arm to drive the elastic plate to move horizontally reciprocally.

[0017] Furthermore, the push assembly includes a cam portion fixedly sleeved on one end of the connecting rod extending into the receiving cavity. When the connecting rod rotates, the protruding portion of the cam portion abuts against the sliding portion, causing the two sliding portions to move in a direction that is relatively far apart to stretch the elastic plate.

[0018] Furthermore, the central hole wall of the fixed sleeve is rotatably fitted with a rolling part, and the periphery of the connecting rod is provided with an irregular rolling groove for the rolling part to engage. The irregular rolling groove includes a connected spiral rolling groove and a straight rolling groove.

[0019] When the rolling part rolls from the straight rolling groove into the spiral rolling groove, it can drive the connecting rod to rotate.

[0020] Furthermore, the elastic element is disposed between the fixed sleeve and the wall of the connecting plate, and the elastic element has an elastic abutting force on the connecting plate in the direction of the gap formed by the two hot rolling rolls.

[0021] Furthermore, a limit nut is fitted onto the upper end of the connecting rod, two stop nuts are installed on the cylinder rod end of the cylinder, and a U-shaped notch is opened at the upper end of the extension arm for the cylinder rod to pass through. The two stop nuts slide in contact with the opposite side walls of the extension arm.

[0022] Furthermore, the flushing chamber is provided in two parts and is respectively abutted against the two sides of the metal plate in the thickness direction. When the metal plate is separated from the flushing chamber, the two flushing chambers move closer to each other under the action of the elastic element and are in abutting and closed state. At the same time, the rolling part rolls from the straight section rolling groove to the spiral rolling groove to trigger the connecting rod to rotate, so that the elastic plate is stretched to clean the iron oxide scale attached to its surface.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, high-pressure flushing water is introduced through the inlet, and the edge of the bottom of the flushing chamber is used to physically scrape off the iron oxide scale that is easy to detach from the surface of the metal plate. At the same time, the impact of low-temperature high-pressure water on the high-temperature iron oxide scale generates huge thermal stress, which causes the oxide scale to detach from the metal matrix quickly. This effectively prevents the oxide film from being pressed into the matrix or remaining at the interlayer bonding interface, ensuring the diffusion of interlayer atoms and metallurgical bonding, and significantly improving the mechanical properties and strengthening effect of the composite plate.

[0025] 2. In this invention, the elastic plate in the device has crests and troughs, causing alternating dynamic and static pressure changes as the flushing water flows through. Combined with the cylinder-driven horizontal reciprocating movement of the elastic plate, the positions of the high dynamic and high static pressure areas within the flushing chamber continuously change, creating a "rubbing" effect on the oxide scale. This causes stress concentration at the contact points of the oxide scale, leading to breakage and peeling. Furthermore, after the water enters the turbulent flow chamber, the dynamic pressure further increases due to the decreasing longitudinal cross-section of the chamber, increasing the outlet flow velocity and effectively preventing the peeled oxide scale from depositing within the flushing chamber.

[0026] 3. In this invention, the flushing water flows from one end of the flushing chamber to the other end along the length direction. This directional flow design avoids the flushing water from splashing onto the surface of the metal plate over a large area, thereby controlling the cooling range and preventing the surface of the metal plate from cooling down too much and affecting the rolling effect of the subsequent hot rolling rolls.

[0027] 4. In this invention, when the metal plate is hot-rolled and detaches from the flushing chamber, the flushing chambers close towards each other under the action of the elastic element. This relative movement triggers the linkage mechanism between the rolling groove and the connecting rod, causing the cam to rotate and stretch the elastic plate, reducing its wave peaks and troughs. When flushing water is introduced at this time, the water flow generates a large shear force as it flows on the flattened surface of the elastic plate, which can automatically and efficiently clean off the muddy iron oxide scale adhering to the surface of the elastic plate, realizing the self-cleaning of the equipment and ensuring the stability of long-term operation.

[0028] 5. In this invention, the equipment utilizes the physical positional changes of the metal plate during "entering the rolling mill" and "leaving the rolling mill" as the driving force. When the metal plate detaches, causing the two flushing chambers to close towards each other, under the action of the elastic element's resisting force, the rolling part automatically slides from the straight rolling groove into the spiral rolling groove, converting linear motion into the rotational motion of the connecting rod, which in turn drives the cam to push the elastic plate to undergo tensile deformation. This series of complex mechanical linkages and self-cleaning actions rely entirely on the equipment's own mechanical reset potential energy, requiring no additional power source; the mechanical design is ingenious and energy-efficient.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-10 This invention provides a technical solution: a hot rolling forming device for interlayer strengthening composite metal sheet and strip, comprising a base 10, a roll support 6 mounted at one end of the base 10, two hot rolling rolls 4 sequentially mounted from top to bottom on the roll support 6, a drive motor 1 mounted at the other end of the base 10, and a transmission box mounted on the base 10. The input shaft of the transmission box is driven and connected to the motor shaft of the drive motor 1, and the two output shafts of the transmission box are driven and connected to the two hot rolling rolls 4 respectively through universal bearings, thereby enabling the two hot rolling rolls 4 to rotate synchronously when the motor shaft of the drive motor 1 rotates. The top of the roll support 6 is equipped with... There is a fixed plate 3, on which two adjusting screws 2 are vertically inserted. The adjusting screws 2 are threadedly connected to the fixed plate 3, and the axial direction of the adjusting screws 2 is perpendicular to the axial direction of the hot rolling roll 4. At the same time, the lower ends of the two adjusting screws 2 are rotatably connected to the two ends of the upper hot rolling roll 4. By rotating the adjusting screws 2, the adjusting screws 2 are threadedly engaged with the fixed plate 3. Since the lower ends of the adjusting screws 2 are rotatably connected to the wall of the hot rolling roll 4, the adjusting screws 2 can drive the uppermost hot rolling roll 4 to move vertically, thereby adjusting the gap between the two hot rolling rolls 4 to adjust the thickness of the metal plate after hot rolling.

[0042] Combination Figures 1 to 10 As shown, and please refer to the following: Figure 4 , Figure 5 and Figure 6 Two mounting brackets 7 are installed on the side wall of the roll support 6 facing the input end of the hot roll 4. The mounting brackets 7 are connected to the roll support 6 by screws, and the two mounting brackets 7 are arranged sequentially from top to bottom. A connecting rod 15 is vertically inserted at each end of the mounting bracket 7 corresponding to the axial direction of the hot roll 4. Two fixing sleeves 16 are fixedly embedded on the mounting bracket 7. The two connecting rods 15 on the same mounting bracket 7 are respectively inserted into the central holes of the two fixing sleeves 16, and can move axially along the central holes of the fixing sleeves 16. By sliding, the upper end of the connecting rod 15 is fitted with a limiting nut 11, which is threaded onto the upper end of the connecting rod 15. The end of the connecting rod 15 away from the limiting nut 11 is connected to the connecting plate 8, and the connecting rod 15 is rotatably connected to the connecting plate 8. A flushing chamber 9 is installed on the side of the connecting plate 8 facing the gap between the two hot rolling rolls 4. A receiving cavity 21 is opened on the side of the flushing chamber 9 facing the connecting plate 8. The receiving cavity 21 is open on the side of the connecting plate 8, and the end of the connecting rod 15 away from the limiting nut 11 extends into the receiving cavity 21.

[0043] Combination Figures 1 to 10 As shown, and please refer to the following: Figure 4 , Figure 6 and Figure 8 A flushing chamber 24 is provided on the side of the flushing chamber 9 facing the gap formed by the two hot rolling rolls 4. The flushing chamber 24 is in a through state with the receiving chamber 21, and the length of the flushing chamber 24 is adapted to the width of the metal sheet to be hot rolled. The length direction of the flushing chamber 24 is parallel to the width direction of the metal sheet. A water inlet 12 is provided on one side wall of the flushing chamber 9 along the length direction. The water inlet 12 is connected to the inner cavity of the flushing chamber 24. A water outlet 23 is provided on the other side wall of the flushing chamber 9 along the length direction. The outlet 23 is connected to the flushing chamber 24. An elastic plate 20 is provided in the receiving chamber 21. The width of the elastic plate 20 is adapted to the width of the inner wall of the receiving chamber 21. The surface of the elastic plate 20 has multiple trough sections 17. The trough sections 17 extend upward towards the flushing chamber 24. The elastic plate 20 can separate the receiving chamber 21 and the flushing chamber 24. The longitudinal direction of the elastic plate 20 corresponds to the longitudinal direction of the flushing chamber 9. Sliding parts 19 are fixed at both ends of the longitudinal direction of the elastic plate 20.

[0044] The sliding part 19 engages in the receiving cavity 21 and slides freely along the length of the flushing chamber 9 within the receiving cavity 21. When the two sliding parts 19 move in a direction that is relatively far apart, they can stretch the elastic plate 20, thereby causing the trough section 17 on the elastic plate 20 to gradually flatten out. When the tension on the sliding part 19 disappears, the elastic plate 20 will recover to a state of multiple troughs and peaks under its own elastic deformation. In addition, a turbulence cavity 22 is provided at one end of the flushing chamber 9 near the outlet 23. The turbulence cavity 22 is connected to the flushing cavity 24 and the outlet 23. The longitudinal height dimension of the inner wall of the turbulence cavity 22 decreases from far to near the outlet 23, and the minimum value of the longitudinal height dimension of the inner wall of the turbulence cavity 22 is adapted to the longitudinal height dimension of the outlet 23.

[0045] Combination Figures 1 to 10 As shown, and please refer to the following: Figure 8 and Figure 9 One end of the connecting rod 15 extending into the receiving cavity 21 is fixedly sleeved with a cam portion 18. When the connecting rod 15 rotates, it will synchronously drive the cam portion 18 to rotate, so that the protruding part of the cam portion 18 generates a thrust on the sliding part 19, causing the sliding part 19 to move towards the outside of the flushing chamber 9 within the receiving cavity 21. This causes the two sliding parts 19 to move away from each other, which will stretch the elastic plate 20. When the protruding part of the cam portion 18 moves away from the sliding part 19, the thrust on the sliding part 19 will disappear. Then, under the action of the elastic deformation recovery ability of the elastic plate 20, the sliding part 19 will move towards the inside of the flushing chamber 9.

[0046] Combination Figures 1 to 10 As shown, and please refer to the following: Figure 6 An extension arm 14 is vertically fixed to the middle part of the elastic plate 20. The end of the extension arm 14 away from the elastic plate 20 passes through the connecting plate 8 and the mounting bracket 7 in sequence. The connecting plate 8 and the mounting bracket 7 are provided with clearance grooves that allow the extension arm 14 to move horizontally freely. A cylinder bracket is installed on the mounting bracket 7, and a cylinder 5 is horizontally installed on the cylinder bracket. Two stop nuts are installed at the end of the cylinder rod of the cylinder 5. A U-shaped notch is provided at the upper end of the extension arm 14. The cylinder rod of the cylinder 5 passes through the U-shaped notch, and the two stop nuts slide in contact with the opposite side walls of the extension arm 14. This allows the extension arm 14 to move vertically without interfering with the cylinder rod of the cylinder 5. At the same time, when the cylinder rod of the cylinder 5 extends or shortens, it can drive the extension arm 14 to move horizontally, thereby driving the elastic plate 20 to move horizontally within the receiving cavity 21.

[0047] Combination Figures 1 to 10 As shown, and please refer to the following: Figure 6 , Figure 8 , Figure 9 and Figure 10 Two rolling parts 25 are rotatably embedded in the central hole wall of the fixed sleeve 16. A shaped rolling groove for engaging the rolling parts 25 is formed around the periphery of the connecting rod 15. This shaped rolling groove includes a spiral rolling groove 27 and a straight rolling groove 26 sequentially from far to near in the direction away from the connecting plate 8. The straight rolling groove 26 and the spiral rolling groove 27 are connected end-to-end, allowing the rolling parts 25 to roll freely within the spiral rolling groove 27 and the straight rolling groove 26. An elastic element 13 is provided between the fixed sleeve 16 and the wall of the connecting plate 8. The two ends of the elastic element 13 elastically abut against the walls of the fixed sleeve 16 and the connecting plate 8, respectively. The elastic element 13 also exerts an elastic abutting force on the connecting plate 8 towards the gap formed by the two hot rolling rollers 4. Furthermore, when the rolling parts 25... When the rolling part 25 rolls from the straight section rolling groove 26 into the spiral rolling groove 27, the rolling part 25 will drive the connecting rod 15 to rotate. When the connecting rod 15 rotates, it will drive the cam part 18 to rotate, so that the protruding part of the cam part 18 presses the sliding part 19, causing the sliding part 19 to move towards the outside of the flushing chamber 9. Specifically, in this embodiment, the elastic element 13 can be set as a spring. The spring is wrapped around the periphery of the connecting rod 15, and the two ends of the spring force direction elastically abut against the end face of the fixed sleeve 16 and the wall surface of the connecting plate 8, respectively. In addition, the rolling part 25 can be set as a ball. The central hole wall of the fixed sleeve 16 has two spherical mounting grooves. The two spherical mounting grooves are symmetrically arranged along the axial direction of the fixed sleeve 16. The two balls are embedded in the spherical mounting grooves and can roll freely.

[0048] Working principle of the invention:

[0049] When the metal plate is rolled by the hot rolling roll 4, the elastic force of the elastic element 13 on the connecting plate 8 causes the connecting plate 8 and the flushing chamber 9 to move toward the surface of the metal plate, so that the surface of the flushing chamber 9 is pressed against the surface of the metal plate. At this time, the two flushing chambers 9 are pressed against the two sides of the metal plate in the thickness direction. The external water pump is started, and the water pump delivers the flushing water to the inlet 12 through the pipeline. The water enters the flushing chamber 24 from the inlet 12. The surface of the opening of the flushing chamber 24 (the opening on the side away from the connecting plate 8) is in contact with the surface of the metal plate. The surface of the metal plate can seal the opening of the flushing chamber 24.

[0050] The multiple troughs 17 of the elastic plate 20 form multiple continuous crests and troughs 17. The longitudinal distance between the troughs 17 and the surface of the metal plate is smaller than that between the crests and the surface of the metal plate. This causes the high-pressure water to exhibit a phenomenon of increased dynamic pressure and decreased static pressure when entering the area between the troughs 17 and the surface of the metal plate, and a phenomenon of increased static pressure and decreased dynamic pressure when entering the area between the crests and the surface of the metal plate. When the iron oxide scale is flushed, its surface temperature drops sharply when it is suddenly impacted by the low-temperature high-pressure water. Due to the difference in thermal expansion coefficients between the iron oxide scale and the steel substrate of the metal plate (the thermal expansion coefficient of the iron oxide scale is usually smaller than that of the steel substrate), this huge temperature difference will generate great thermal stress, which allows the iron oxide scale to detach from the surface of the metal plate. Then, it enters the turbulent flow chamber 22 from the flushing chamber 24 with the flushing water flow, and then is discharged from the outlet 23.

[0051] As the flushing water flows from one end of the flushing chamber 9 to the other along its length, its kinetic energy gradually weakens, thus reducing the flushing force on the iron oxide scale. In this embodiment, during the flushing process, the cylinder 5 is activated, and the cylinder rod of the cylinder 5 extends and retracts repeatedly, allowing the extension arm 14 to move horizontally back and forth. This, in turn, drives the elastic plate 20 to move horizontally back and forth within the receiving cavity 21. This causes the areas with high dynamic pressure and low static pressure and areas with low dynamic pressure and high static pressure within the flushing cavity 24 to change position. The flushing water has a higher flow velocity in the areas with high dynamic pressure and low static pressure. Through the reciprocating extension and retraction of the cylinder rod of the cylinder 5, the hot rolling roller 4 slowly conveys the metal plate during hot rolling. This allows the iron oxide scale on the surface of the metal plate to be subjected to the effects of dynamic and static pressure changes of the flushing water in a short period of time.

[0052] Under varying pressure, the iron oxide scale is essentially kneaded, causing stress concentration and breakage at the contact points between the scale and the steel substrate. As the scale falls off, it enters the turbulent chamber 22 with the water flow, where the dynamic pressure gradually increases. This results in a higher flow velocity of the scale at the outlet 23, reducing the deposition of scale in the flushing chamber 24. Additionally, during the conveying process by the hot rolling roll 4, the bottom edge of the flushing chamber 9 can scrape off the easily detachable iron oxide scale from the surface of the metal plate. Furthermore, since the flushing water flows from one end of the flushing chamber 9 to the other along its length, it prevents the flushing water from splashing onto the surface of the metal plate over a large area, thus avoiding excessive cooling of the metal plate surface and affecting the hot rolling effect of the hot rolling roll 4.

[0053] After the metal sheet is hot-rolled, the iron oxide scale may form a mud-like substance under the action of the flushing water, which then adheres to the surface of the crest and trough sections 17 of the elastic plate 20. When the metal sheet detaches from the surface of the flushing chamber 9, the two flushing chambers 9 will move closer to each other, so that the opposing surfaces of the two flushing chambers 9 are in abutting state. At the same time, after the opposing surfaces abut, they can be closed. Then, the external water pump delivers flushing water to the flushing chambers 24 of the two flushing chambers 9 respectively. Previously, when the flushing chambers 9 abutted the surface of the metal sheet, the opposing surfaces of the two flushing chambers 9 had a longitudinal distance equal to the thickness of the metal sheet. The rolling part 25 was engaged in the straight section rolling groove 26 and did not enter the spiral rolling groove 27. Now, after the metal sheet detaches from the flushing chambers 9, the two flushing chambers 9 move closer to each other under the action of the flushing water. Under the elastic resistance of the connecting plate 8, the elastic component 13 will move towards the relatively closer direction, causing the rolling part 25 to start rolling from the straight section rolling groove 26 into the spiral rolling groove 27, thereby causing the connecting rod 15 to rotate. When the connecting rod 15 rotates, it will drive the cam part 18 to rotate, causing the protruding part of the cam part 18 to rotate and abut against the sliding part 19, causing the two sliding parts 19 to move towards the relatively farther direction, thereby producing a stretching effect on the elastic plate 20, reducing the undulation height of the trough section 17 and the crest section on the elastic plate 20. Thus, when the flushing water enters the flushing chamber 24, when the flushing water flows on the surface of the elastic plate 20, the shearing force on the iron oxide scale mud attached to the surface of the elastic plate 20 is large, thereby effectively cleaning off the iron oxide scale mud.

[0054] In addition, during the hot rolling of the metal sheet, the connecting rod 15 is first pulled away from the gap formed by the two hot rolling rollers 4, so that the rolling part 25 rolls in the straight section rolling groove 26, thereby creating a large gap between the opposite surfaces of the two flushing chambers 9, allowing the metal sheet to pass through the gap and be bitten into by the two hot rolling rollers 4. Once bitten in, the connecting rod 15 is released, and under the action of the elastic abutment force of the elastic member 13, the driving connecting rod 15 is moved towards the metal sheet, thereby causing the two flushing chambers 9 to abut against the two sides of the metal sheet in the thickness direction. In this embodiment, the elastic abutment force of the elastic member 13 against the connecting plate 8 is sufficient to drive the connecting rod 15 to rotate, so that the cam part 18 overcomes the elastic deformation resistance of the elastic plate 20 itself, thereby causing the protruding part of the cam part 18 to abut against the sliding part 19, causing the two sliding parts 19 to move relative to each other, thereby allowing the elastic plate 20 to be stretched.
