Description

Technical Field

[0001] This invention relates to the field of steel plate rolling technology, and more specifically, to a thin steel plate production rolling equipment and forming method. Background Technology

[0002] Thin steel sheets are one of the most commonly used metal sheets in industrial production. Their thickness, surface quality, and flatness are typically controlled through rolling equipment. Thin steel sheet rolling equipment generally includes a frame, rolls, a drive assembly, and an inlet support structure located on the feed side of the rolls. The drive assembly drives the rolls to rotate, while the inlet support structure supports and guides the thin steel sheet before it enters the rolling zone between the rolls, ensuring the sheet enters the rolling zone with a relatively stable posture.

[0003] In the existing cold rolling process of thin steel plates, in order to reduce rolling friction, reduce wear on the rolls and the surface of the thin steel plate, and improve the surface quality after rolling, rolling oil, emulsion or other lubricating coolant is usually sprayed in the rolling area or near the rolls. After spraying, some of the rolling oil will adhere to the surface of the thin steel plate, some will adhere to the surface of the rolls, and some will fall onto the inlet support structure on the feed side of the rolls due to dripping, splashing or backflow.

[0004] In the above rolling process, thin steel plates usually need to be supported by an inlet support structure before entering the rolls. Existing inlet support structures mostly use flat plate trays or ordinary guide trays. Their main function is to support and guide the thin steel plates into the rolls. For plates with larger thickness or better rigidity, ordinary flat plate trays can meet the basic feeding support requirements. When the plate slides on the tray, it is not easily affected by the small amount of residual liquid on the tray surface.

[0005] However, for single thin steel sheets, due to their small thickness, light weight, and relatively flat lower surface, when the rolling oil under cold rolling spray lubrication conditions remains on the surface of the inlet pallet, a continuous liquid film is easily formed between the lower surface of the thin steel sheet and the inlet pallet. This continuous liquid film will cause adhesion and viscous resistance between the thin steel sheet and the inlet pallet, which can easily lead to problems such as feeding jamming, sudden slippage, plate head shaking, or skewed entry into the rolls before the thin steel sheet is bitten by the rolls. This will affect the posture stability of the thin steel sheet when it enters the rolls and may cause scratches on the lower surface of the thin steel sheet, plate head creases, and unstable quality in the initial stage of rolling. Summary of the Invention

[0006] The present invention provides a thin steel plate production rolling equipment and forming method, which aims to solve the following problem: Under cold rolling spray lubrication conditions, existing thin steel plate rolling equipment tends to retain rolling oil on the surface of the inlet pallet, resulting in the formation of a continuous liquid film between the lower surface of a single thin steel plate and the inlet pallet, thereby causing adhesion and feeding stickiness, which affects the stable entry of the thin steel plate into the roll.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a thin steel plate production rolling equipment, comprising: a rolling equipment, the rolling equipment including a frame, rolls, a drive assembly, and an anti-adsorption inlet support mechanism disposed on the feed side of the rolls, the rolls being rotatably disposed on the frame and driven to rotate by the drive assembly, for rolling the thin steel plate entering the rolling area of ​​the rolls;

[0008] The anti-adsorption inlet support mechanism includes a support plate and a drainage assembly. The support plate is located on the feed side of the roll and is used to support the thin steel plate before it enters the roll.

[0009] The pallet is provided with multiple supporting ribs, which are used to create an intermittent support state between the lower surface of the thin steel plate and the pallet. The multiple supporting ribs extend along the feeding direction of the thin steel plate and are arranged at intervals along the width direction of the thin steel plate. A drainage groove is formed between two adjacent supporting ribs, which is used to contain and guide the liquid between the lower surface of the thin steel plate and the pallet.

[0010] The drain assembly is connected to the drain tank and is used to drain the rolling oil in the drain tank.

[0011] In a preferred embodiment, the drain assembly includes an oil collecting seat, a liquid guiding hole, and a drain hole. The oil collecting seat is located below the support plate, the liquid guiding hole is located at the bottom of the drain trough and communicates with the oil collecting seat, and the drain hole is located on the oil collecting seat to drain the liquid that enters the oil collecting seat through the liquid guiding hole. In a preferred embodiment, the drain trough extends along the feeding direction of the thin steel plate, and the bottom of each drain trough is provided with multiple liquid guiding holes at intervals along its length.

[0012] In a preferred embodiment, the drain trough is further provided with an interrib support mechanism, which includes multiple support strips disposed in the corresponding drain troughs to provide auxiliary support for the portion of the large-format thin steel plate located between adjacent support ribs.

[0013] In a preferred embodiment, the interrib support mechanism further includes a support adjustment component for adjusting the horizontal swing angle of the support bar relative to the feeding direction of the thin steel plate in the drainage trough, so as to change the planar support coverage of the support bar in the drainage trough.

[0014] In a preferred embodiment, the support adjustment assembly includes a linear drive assembly, a connecting bar, a round shaft, a rotating shaft, and a rectangular frame. The support bar and the rectangular frame are both fixedly connected to the rotating shaft, which is rotatably mounted on the oil collection seat. The connecting bar is fixedly connected to the output end of the linear drive assembly. The round shaft includes multiple round shafts, which are fixedly mounted on the connecting bar and movably connected within the corresponding rectangular frames.

[0015] In a preferred embodiment, the bottom of the oil collecting seat is provided with a height adjustment mechanism, which is used to adjust the height difference between the upper supporting surface of the support bar and the upper supporting surface of the support rib.

[0016] In a preferred embodiment, the height adjustment mechanism includes a second linear drive assembly, a crossbar, a rotating cylinder, and a guide assembly. The guide assembly includes a guide bar and a guide groove. The second linear drive assembly is used to drive the crossbar to move. The crossbar cooperates with the guide assembly through the rotating cylinder to drive the support bar to make fine adjustments to its height within the drainage tank.

[0017] In a preferred embodiment, the drive assembly includes a drive component mounted on a frame, a drive gear mounted on the output end of the drive component, two rolls, each roll having a driven gear mounted on its end, the two driven gears meshing with each other, and the drive gear meshing with one of the driven gears.

[0018] A forming method for a thin steel plate production rolling mill includes the following steps:

[0019] Step 1: Drive the two rollers to rotate through the drive assembly, and convey the thin steel plate to be rolled to the pallet of the anti-adsorption inlet support mechanism along the feeding direction;

[0020] Step 2: When the thin steel plate moves on the pallet, multiple supporting ribs provide intermittent support to the lower surface of the thin steel plate, thereby breaking the continuous liquid film between the lower surface of the thin steel plate and the pallet. At the same time, the liquid carried by the lower surface of the thin steel plate or retained on the surface of the pallet enters the drainage channel between adjacent supporting ribs.

[0021] Step 3: The liquid entering the drain tank enters the oil collection seat through the liquid guide hole and is discharged through the drain hole to reduce the adhesion and viscous resistance between the thin steel plate and the support plate.

[0022] Step 4: Adjust the horizontal swing angle of the support bar in the drainage tank by using the support adjustment component, so that the support bar provides auxiliary support for the thin steel plate in the area between adjacent support ribs;

[0023] Step 5: Adjust the height difference between the upper support surface of the support strip and the upper support surface of the support rib by adjusting the height adjustment mechanism to change the timing of the support strip's auxiliary support intervention on the thin steel plate.

[0024] Step 6: After being supported by the anti-adsorption inlet support mechanism and the interrib support mechanism, the thin steel plate enters the rolling area of ​​the rolls, where it is rolled into shape by the rolls.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention sets up an anti-adsorption inlet support mechanism, which allows the thin steel plate to be supported intermittently by the supporting ribs, and allows the liquid between the lower surface of the thin steel plate and the support plate to enter the drainage tank and be discharged, thereby breaking the continuous liquid film, reducing the adhesion and viscous resistance of the thin steel plate during the feeding process, and improving the stability of the thin steel plate before entering the roll.

[0027] By setting up an interrib support mechanism, this invention can provide auxiliary support for the area between adjacent support ribs of large-format thin steel plates without canceling the drainage function of the drainage trough. This reduces the sinking of the thin steel plates between the ribs above the drainage trough and reduces the problem of local micro-waveforms and unstable posture before entering the roller.

[0028] This invention, by setting up a support adjustment component and a height adjustment mechanism, enables the support strip to be adjusted in horizontal swing angle and finely adjusted in height, thereby adjusting the support range and the timing of support intervention according to the sinking of thin steel plates of different specifications, taking into account the effects of drainage, anti-adsorption, sinking limitation and anti-abrasion.

[0041] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Refer to the instruction manual appendix Figures 1 to 4 A thin steel plate production rolling equipment includes: a rolling equipment 1, which includes a frame 11, a roll 12, a drive assembly 13, and an anti-adsorption inlet support mechanism 2 disposed on the feed side of the roll 12. The roll 12 is rotatably disposed on the frame 11 and is driven to rotate by the drive assembly 13 for rolling the thin steel plate entering the rolling area of ​​the roll 12.

[0043] The anti-adsorption inlet support mechanism 2 includes a support plate 21 and a drain assembly 22. The support plate 21 is disposed on the feed side of the roll 12 and is used to support the thin steel plate before it enters the roll 12.

[0044] The pallet 21 is provided with multiple supporting ribs 211. The multiple supporting ribs 211 are used to form an intermittent support state between the lower surface of the thin steel plate and the pallet 21. The multiple supporting ribs 211 extend along the feeding direction of the thin steel plate and are arranged at intervals along the width direction of the thin steel plate. A drain groove 212 is formed between two adjacent supporting ribs 211. The drain groove 212 is used to contain and guide the liquid between the lower surface of the thin steel plate and the pallet 21.

[0045] The drain assembly 22 is connected to the drain tank 212 and is used to drain the rolling oil in the drain tank 212.

[0046] It should be noted that when the thin steel plate is supported by the anti-adsorption inlet support mechanism 2 and enters the roll 12, multiple supporting ribs 211 are used to form an intermittent support state between the lower surface of the thin steel plate and the support plate 21. The drain trough 212 is used to contain and guide the liquid between the lower surface of the thin steel plate and the support plate 21, thereby breaking the continuous liquid film between the lower surface of the thin steel plate and the support plate 21, thus reducing the adhesion, adsorption and viscous resistance of the thin steel plate during the feeding process.

[0047] It should be noted that the supporting ribs 211 extend along the feeding direction of the thin steel plate, which allows the thin steel plate to slide along the extension direction of the supporting ribs 211 during the feeding process. This avoids the thin steel plate getting stuck due to frequently crossing the protruding structure during feeding. Multiple supporting ribs 211 are arranged at intervals along the width direction of the thin steel plate, which can form multiple support areas in the width direction of the thin steel plate. This allows the thin steel plate to be supported while the drainage grooves 212 for containing liquid are still retained between the supporting ribs 211. This ensures that the supporting ribs 211 can provide support for the thin steel plate without causing the lower surface of the thin steel plate to re-form large-area contact with the support plate 21.

[0048] It should also be noted that the bottom of the drain trough 212 is lower than the upper support surface of the support rib 211. The upper support surface of the support rib 211 can be set as an arc surface, a rounded surface, or a smooth transition surface. This is used to reduce the contact area of ​​the lower surface of the thin steel plate while reducing the risk of the support rib 211 scratching the lower surface of the thin steel plate. A liquid-blocking end can be set at one end of the drain trough 212 near the roll 12. The liquid-blocking end is used to restrict the liquid in the drain trough 212 from continuing to flow into the rolling area of ​​the roll 12, thereby reducing the probability of liquid accumulating at the inlet of the roll 12. At least one drain position connected to the drain assembly 22 can be set near the liquid-blocking end so that the liquid flowing to the end of the drain trough 212 can be discharged in time.

[0049] In this embodiment, the specific implementation scenario is as follows: the thin steel plate is a single sheet of thin steel plate. Under the condition of cold rolling spray lubrication or rolling oil assisted feeding, the thin steel plate is fed above the pallet 21. Since the thin steel plate is thin and light, if the pallet 21 is a normal planar structure, the lower surface of the thin steel plate is easy to form a continuous liquid film with the rolling oil remaining on the surface of the pallet 21, thereby generating adhesion and viscous resistance. Through the anti-adsorption inlet support mechanism 2, the lower surface of the thin steel plate is first supported by multiple supporting ribs 211, so that the lower surface of the thin steel plate and the pallet 21 change from a large area surface contact to a multi-interval support state. At the same time, the drain trough 212 located between adjacent supporting ribs 211 can accommodate the liquid carried by the lower surface of the thin steel plate and the liquid retained on the surface of the pallet 21, so that the liquid enters the drain trough 212 and is discharged by the drain assembly 22, thereby breaking the continuous liquid film between the lower surface of the thin steel plate and the pallet 21, reducing the adsorption resistance and viscous resistance when the thin steel plate is fed.

[0050] Further, please refer to the appendix to the instruction manual. Figure 3 , Figure 4 The drainage assembly 22 includes an oil collection seat 221, a liquid guiding hole 222, and a drainage hole 223. The oil collection seat 221 is located below the support plate 21. The liquid guiding hole 222 is located at the bottom of the drainage tank 212 and communicates with the oil collection seat 221. The drainage hole 223 is located on the oil collection seat 221 and is used to discharge the liquid that enters the oil collection seat 221 through the liquid guiding hole 222.

[0051] It should be noted that when the thin steel plate enters the roll 12 along the support plate 21, the liquid carried on the lower surface of the thin steel plate or the liquid retained on the surface of the support plate 21 is guided into the drain trough 212. The liquid entering the drain trough 212 flows to the liquid guide hole 222 at the bottom of the drain trough 212 under its own gravity, and enters the oil collection seat 221 through the liquid guide hole 222. The liquid entering the oil collection seat 221 is then discharged through the drain hole 223, thus completing the drain process from the drain trough 212 to the oil collection seat 221 and then discharged from the oil collection seat 221. Through the above structure, it is possible to avoid the liquid from staying on the upper surface of the support plate 21 for a long time, and also to reduce the probability of the liquid in the drain trough 212 spreading to the lower surface of the thin steel plate again.

[0052] Further, please refer to the appendix to the instruction manual. Figure 3 , Figure 4 The drain trough 212 extends along the feeding direction of the thin steel plate, and the bottom of each drain trough 212 is provided with multiple liquid guiding holes 222 at intervals along its length, so that the liquid in the drain trough 212 can enter the oil collection seat 221 in sections along the feeding direction of the thin steel plate, which can reduce the retention of liquid on the upper surface of the tray 21.

[0053] It should be noted that when the thin steel plate moves on the pallet 21, the liquid is not concentrated at a fixed position on the pallet 21, but may be carried along the feeding direction along the lower surface of the thin steel plate. If each drain trough 212 is provided with only one guide hole 222, the liquid at a position far from the guide hole 222 needs to flow a long distance in the drain trough 212 before it can be discharged, which can easily cause local liquid accumulation. Especially when the rolling oil viscosity is high or the spray lubrication volume is large, the liquid in the drain trough 212 may not be able to be discharged in time and will come into contact with the lower surface of the thin steel plate again. Therefore, in this embodiment, multiple guide holes 222 are provided at intervals along the length direction at the bottom of each drain trough 212, so that the liquid at different positions in the drain trough 212 can enter the corresponding guide hole 222 nearby, thereby shortening the flow distance of the liquid in the drain trough 212 and improving the drainage speed.

[0054] In the above technical solution, the anti-adsorption inlet support mechanism 2, by setting multiple support ribs 211 and drainage grooves 212 on the pallet 21, can change the large-area surface contact between the lower surface of the thin steel plate and the pallet 21 to an intermittent support, and allow the rolling oil carried on the lower surface of the thin steel plate or the rolling oil retained on the surface of the pallet 21 to enter the drainage groove 212 for discharge, thereby breaking the continuous liquid film and reducing the adhesion, adsorption and viscous resistance when the thin steel plate is fed. However, the thin steel plate is not continuously supported by the entire upper surface of the pallet 21, but is mainly supported by the support ribs 211 arranged at intervals along the width direction of the thin steel plate. Drainage grooves 212 are formed between adjacent support ribs 211 for drainage. When the thin steel sheet to be rolled is a standard-sized sheet, its inherent rigidity is usually sufficient to overcome the gap between adjacent supporting ribs 211, making significant deformation unlikely. However, when the thin steel sheet to be rolled is a large-format single sheet, its overall bending stiffness is low due to its larger width and length and smaller thickness. The area between adjacent supporting ribs 211 is prone to sagging towards the drain trough 212, causing local micro-waves to form on the thin steel sheet before entering the roll 12. Simultaneously, the top of the supporting ribs 211 forms a relatively concentrated narrow band of support on the lower surface of the thin steel sheet, easily leading to support marks, localized scratches, unstable roll entry posture, and a decrease in sheet shape quality in the initial rolling stage. Therefore, while maintaining the drain trough 212's function of draining liquid and disrupting the continuous liquid film, further auxiliary support is needed for the sagging area between adjacent supporting ribs 211 on the large-format thin steel sheet.

[0055] Further, please refer to the appendix to the instruction manual. Figures 5 to 7 The drain trough 212 is also provided with a rib support mechanism 3. The rib support mechanism 3 includes multiple support bars 31. The multiple support bars 31 are set in the corresponding drain trough 212 and are used to provide auxiliary support for the part of the large-format thin steel plate located between adjacent support ribs 211.

[0056] It should be noted that after the thin steel plate enters the pallet 21 along the feeding direction, the lower surface of the thin steel plate is first supported by multiple supporting ribs 211 at intervals. The rolling oil carried on the lower surface of the thin steel plate or the rolling oil retained on the surface of the pallet 21 enters the drain groove 212 between adjacent supporting ribs 211. When the thin steel plate is a large-format thin steel plate, the part of the thin steel plate located between adjacent supporting ribs 211 moves downward and approaches the drain groove 212. At this time, the supporting strip 31 set in the drain groove 212 provides auxiliary support for the sunken area, so that the area of ​​the thin steel plate above the drain groove 212 will not continue to sink significantly, thereby improving the flatness of the thin steel plate before entering the roll 12.

[0057] It should also be noted that the support strip 31 can be a long strip, a plate, a round rod, a narrow strip, or an irregularly shaped strip structure with a smooth support surface at the top. The support strip 31 extends along the length of the drainage channel 212, or is segmented along a local length of the drainage channel 212; one support strip 31 can be provided in each drainage channel 212, or multiple support strips 31 can be provided along the length or width of the drainage channel 212, as long as the support strip 31 can provide auxiliary support for the area of ​​the thin steel plate located between adjacent support ribs 211.

[0058] It should be further explained that the upper supporting surface of the support strip 31 can be lower than or not higher than the upper supporting surface of the support rib 211, so that the support rib 211 still serves as the main supporting part of the thin steel plate, while the support strip 31 serves as an auxiliary supporting part when the thin steel plate experiences interrib sagging. With this structure, when the sagging of the thin steel plate is small, the thin steel plate is mainly supported by the support rib 211, and the support strip 31 will not generate excessive friction on the lower surface of the thin steel plate; when the sagging of the thin steel plate increases, the support strip 31 provides supplementary support to the lower surface of the thin steel plate, thereby avoiding premature contact of the support strip 31 with the lower surface of the thin steel plate and the generation of unnecessary support marks.

[0059] Further, please refer to the appendix to the instruction manual. Figure 7 The interrib support mechanism 3 also includes a support adjustment component 32. The support adjustment component 32 is used to adjust the horizontal swing angle of the support bar 31 relative to the feeding direction of the thin steel plate in the drain trough 212, so as to change the planar support coverage of the support bar 31 in the drain trough 212. The support adjustment component 32 includes a linear drive component 321, a connecting bar 322, a round shaft 323, a rotating shaft 324, and a rectangular frame 325. The support bar 31 and the rectangular frame 325 are both fixedly connected to the rotating shaft 324. The rotating shaft 324 is rotatably mounted on the oil collection seat 221. The connecting bar 322 is fixedly connected to the output end of the linear drive component 321. The round shaft 323 includes multiple round shafts, which are fixedly mounted on the connecting bar 322 and movably connected in the corresponding rectangular frame 325.

[0060] It should be noted that when the thin steel plate to be rolled has good rigidity or a small amount of sag, the horizontal swing angle of the support strip 31 can be reduced by adjusting the support adjustment component 32, so that the support strip 31 is arranged more along the extension direction of the drain groove 212, so as to retain a larger drain space and reduce the influence of the support strip 31 on the flow of oil in the drain groove 212. When the thin steel plate to be rolled has a large width, a small thickness, or a significant sag between adjacent support ribs 211, the horizontal swing angle of the support strip 31 can be increased by adjusting the support adjustment component 32, so that the support strip 31 forms a larger planar support coverage area in the drain groove 212, thereby providing more sufficient auxiliary support for the rib sag area of ​​the thin steel plate.

[0061] It should also be noted that when the horizontal swing angle of the support bar 31 needs to be adjusted, the connecting bar 322 is driven to move linearly by the linear drive assembly 321. When the connecting bar 322 moves, the multiple round shafts 323 fixed on the connecting bar 322 move synchronously. Since the multiple round shafts 323 are movably connected to the corresponding rectangular frame 325, the round shafts 323 will push the inner wall of the rectangular frame 325 during the movement, causing the rectangular frame 325 to swing around the rotation axis 324. The rectangular frame 325 is fixedly connected to the rotation axis 324. Therefore, when the rectangular frame 325 swings, it drives the rotation axis 324 to rotate. The support bar 31 is fixedly connected to the rotation axis 324. Therefore, when the rotation axis 324 rotates, it drives the support bar 31 to change the horizontal swing angle synchronously in the drain tank 212.

[0062] In the above technical solution, by setting a support strip 31 in the drain trough 212 and adjusting the horizontal swing angle of the support strip 31 relative to the feeding direction of the thin steel plate using the support adjustment component 32, the planar support coverage of the support strip 31 in the drain trough 212 can be changed. This allows the support strip 31 to maintain the draining function of the drain trough 212 while providing auxiliary support for the area between adjacent support ribs 211 of the large-format thin steel plate, thereby reducing the sagging between the ribs of the large-format thin steel plate. However, when the same equipment needs to roll large-format thin steel plates of different thicknesses, different rigidities, or different aspect ratios... When rolling, the actual amount of depression between adjacent support ribs 211 varies for different thin steel plates. If the height of the upper support surface of the support strip 31 is fixed, for thin steel plates with good rigidity and small depression, the support strip 31 may contact the lower surface of the thin steel plate too early, increasing unnecessary sliding friction and forming support bright marks or local scratches. For thinner steel plates with poorer rigidity and larger depression, the support strip 31 may intervene too late due to its low height, resulting in interrib depression, local micro-waves, and unstable roll entry posture of the thin steel plate before entering the roll 12. Therefore, in addition to adjusting the horizontal swing angle of the support strip 31, it is necessary to further adjust the height difference between the upper support surface of the support strip 31 and the upper support surface of the support rib 211, so that the support strip 31 can change the intervention timing and support strength of the auxiliary support according to the actual depression of thin steel plates of different specifications.

[0063] For details, please refer to the instruction manual appendix. Figures 8 to 10 The bottom of the oil collection seat 221 is provided with a height adjustment mechanism 4, which is used to adjust the height difference between the upper support surface of the support strip 31 and the upper support surface of the support rib 211.

[0064] It should be noted that when the thin steel plate to be rolled has good rigidity, relatively large thickness, or small amount of depression between adjacent support ribs 211, the support strip 31 can be positioned lower relative to the support ribs 211 by the height adjustment mechanism 4. In this case, the thin steel plate is mainly supported by the support ribs 211, and the support strip 31 is less likely to contact the lower surface of the thin steel plate too early, thereby reducing unnecessary sliding friction and support bright marks. When the thin steel plate to be rolled has small thickness, poor rigidity, or large amount of depression between adjacent support ribs 211, the support strip 31 can be appropriately raised by the height adjustment mechanism 4, so that the support strip 31 contacts the depression area of ​​the thin steel plate above the drain trough 212 earlier, providing auxiliary support for the thin steel plate, thereby reducing the interrib depression and local micro-waves before the thin steel plate enters the roll 12.

[0065] Further, please refer to the appendix to the instruction manual. Figure 9 , Figure 10The height adjustment mechanism 4 includes a linear drive assembly 41, a crossbar 42, a rotating cylinder 43, and a guide assembly 44. The guide assembly 44 includes a guide bar 441 and a guide groove 442. The linear drive assembly 41 is used to drive the crossbar 42 to move. The crossbar 42 cooperates with the guide assembly 44 through the rotating cylinder 43 to drive the support bar 31 to adjust its height in the drain tank 212. The rotating shaft 324 is rotatably mounted on the crossbar 42.

[0066] It should be noted that the linear drive assembly 41 can be a cylinder, electric push rod, hydraulic cylinder, linear motor, lead screw slide, or other drive components capable of outputting linear displacement. When the support bar 31 needs to be raised, the linear drive assembly 41 pushes the crossbar 42 upward, and the crossbar 42 drives the rotating shaft 324 to move synchronously, causing the support bar 31 to move upward. This makes the upper support surface of the support bar 31 closer to the upper support surface of the supporting rib 211, allowing the support bar 31 to provide auxiliary support for the sunken thin steel plate earlier. When the support bar 31 needs to be lowered, the output end of the linear drive assembly 41 moves in the opposite direction, causing the support bar 31 to move downward, thereby increasing the height difference between the upper support surface of the support bar 31 and the upper support surface of the supporting rib 211. In this case, for thin steel plates with good rigidity or small amount of sunkenness, the support bar 31 should not contact the lower surface of the thin steel plate too early, which can reduce unnecessary friction contact and support marks.

[0067] Further, please refer to the appendix to the instruction manual. Figure 1 The drive assembly 13 includes a drive component 131 mounted on the frame 11. A drive gear 132 is mounted on the output end of the drive component 131. The rollers 12 include two rollers. A driven gear 133 is mounted on the end of each roller 12. The two driven gears 133 mesh with each other, and the drive gear 132 meshes with one of the driven gears 133.

[0068] It should be noted that the drive component 131 can be a power source capable of outputting rotational power, such as a servo motor, frequency converter, ordinary geared motor, hydraulic motor, or pneumatic motor. The drive component 131 drives the drive gear 132 to rotate, and the drive gear 132 drives one of the driven gears 133 meshing with it to rotate. The driven gear 133 drives a roller 12 fixedly connected to it to rotate. Since the two driven gears 133 mesh with each other, the other driven gear 133 rotates synchronously in the opposite direction and drives the other roller 12 to rotate in the opposite direction, so that the two rollers 12 can rotate synchronously in opposite directions, so that the thin steel plate located between the two rollers 12 is clamped and pulled into the rolling area, thereby realizing the rolling and forming of the thin steel plate.

[0069] Refer to the instruction manual appendix Figure 11 A forming method for a thin steel plate production rolling equipment includes the following steps:

[0070] Step 1: Drive the two rollers 12 to rotate through the drive assembly 13, and transport the thin steel plate to be rolled along the feeding direction to the pallet 21 of the anti-adsorption inlet support mechanism 2;

[0071] Step 2: When the thin steel plate moves on the pallet 21, multiple supporting ribs 211 provide intermittent support to the lower surface of the thin steel plate, thereby breaking the continuous liquid film between the lower surface of the thin steel plate and the pallet 21. At the same time, the liquid carried by the lower surface of the thin steel plate or the liquid retained on the surface of the pallet 21 enters the drainage groove 212 between adjacent supporting ribs 211.

[0072] Step 3: The liquid entering the drain tank 212 enters the oil collection seat 221 through the liquid guide hole 222 and is discharged through the drain hole 223 to reduce the adhesion and viscous resistance between the thin steel plate and the support plate 21.

[0073] Step 4: Adjust the horizontal swing angle of the support bar 31 in the drainage tank 212 by using the support adjustment component 32, so that the support bar 31 provides auxiliary support for the thin steel plate in the area between adjacent support ribs 211.

[0074] Step 5: Adjust the height difference between the upper support surface of the support strip 31 and the upper support surface of the support rib 211 by adjusting the height adjustment mechanism 4, thereby changing the timing of the auxiliary support intervention of the support strip 31 on the thin steel plate.

[0075] Step 6: After being supported by the anti-adsorption inlet support mechanism 2 and the interrib support mechanism 3, the thin steel plate enters the rolling area of ​​the roll 12, where the roll 12 rolls the thin steel plate into shape.

[0076] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
