Through the adjustment function of the horizontal adjustment mechanism, the position of the toothed rollers can be quickly adjusted when there are deviations in the width of the steel strip or when changing to steel strips of different widths. This avoids excessive compression deformation or missed processing of the steel strip sides due to horizontal position deviations, thus preventing deformation problems caused by horizontal deviations. Furthermore, it reduces operation time during specification changes, thereby improving the adaptability of the device to different specifications of steel strips, ensuring the stability of processing quality, and increasing production efficiency.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.
[0020] See Figure 1 and Figure 2This invention discloses a synchronous steel strip gear rolling device, including a frame 1, an upper roller pressing mechanism 2, a lower roller pressing mechanism 3, and a horizontal adjustment mechanism 4 mounted on the frame 1. The frame 1 provides support for the overall structure and includes side plates 11. The roller pressing mechanism and the horizontal adjustment mechanism 4 are disposed between the two side plates 11. The side plates 11 serve as supporting components, confining the upper roller pressing mechanism 2, the lower roller pressing mechanism 3, and the horizontal adjustment mechanism 4 between the two side plates 11, ensuring the relative position stability of each component and providing a basic framework for the stable conveying of the steel strip 7 and the gear rolling 41 processing. The upper roller pressing mechanism 2 includes an upper pressure roller 21, and the lower roller pressing mechanism 3 includes a lower pressure roller 31. The upper pressure roller 21 and the lower pressure roller 31 are arranged parallel to each other, and a gap 6 is provided between the upper pressure roller 21 and the lower pressure roller 31. The steel strip 7 enters the synchronous steel strip gear rolling device through the gap 6. After the steel strip 7 enters the device through the gap 6, it is continuously and smoothly conveyed by the cooperation of the upper pressure roller 21 and the lower pressure roller 31, providing stable feeding conditions for the hobbing of the gears 41 on both sides.
[0021] Two horizontal adjustment mechanisms 4 are respectively connected to the two side plates 11 and arranged opposite each other. Each horizontal adjustment mechanism 4 includes a gear hobbing 41 and a horizontal adjustment rod 42. The gear hobbing 41 of the two horizontal adjustment mechanisms 4 is respectively arranged on both sides of the gap 6. The gear hobbing 41 abuts against both sides of the steel strip 7 to form the gear hobbing 41 on both sides of the steel strip 7. The horizontal adjustment rod 42 is used to adjust the distance from the gear hobbing 41 to the gap 6. When the gear hobbing 41 abuts against both sides of the steel strip 7 entering the gap 6, it can directly form the gear hobbing 41 on both sides of the steel strip 7; while the setting of the horizontal adjustment rod 42 allows the distance from the gear hobbing 41 to the gap 6 to be flexibly adjusted.
[0022] Specifically, when the width of the steel strip 7 to be processed deviates or when it is necessary to replace it with a steel strip 7 of different width specifications, the position of the hobbing teeth 41 on both sides can be quickly adjusted by operating the horizontal adjustment rod 42, so that the hobbing teeth 41 always accurately abut against both sides of the steel strip 7, thereby ensuring uniform forming depth and consistent tooth profile accuracy of the hobbing teeth 41, solving the problem of poor forming accuracy caused by the inability to adjust the position in the existing fixed structure. At the same time, this adjustment method does not require the overall disassembly and assembly of the hobbing teeth 41, avoiding excessive extrusion deformation or missed processing caused by horizontal position deviation of the steel strip 7, reducing the operation time when changing specifications, and enabling the device to adapt to steel strips 7 of different width specifications, effectively improving the stability of processing quality and production efficiency.
[0023] The beneficial effects of the embodiments of the present invention are as follows: The synchronous steel strip tooth rolling device of this invention includes a frame 1, an upper pressure roller 21, a lower pressure roller 31, and two opposing horizontal adjustment mechanisms 4. Each horizontal adjustment mechanism 4 includes toothed rollers 41 and a horizontal adjustment rod 42, with the two toothed rollers 41 respectively positioned on both sides of the gap 6. By adjusting the distance between the toothed rollers 41 and the gap 6 using the horizontal adjustment rod 42, the toothed rollers 41 can precisely abut against the sides of steel strips 7 of different widths, ensuring uniform forming depth and consistent tooth profile accuracy, thereby improving the precision of the roll forming process. Through the adjustment function of the horizontal adjustment mechanism 4, the position of the toothed rollers 41 can be quickly adjusted when there is a deviation in the width of the steel strip 7 or when changing to a steel strip 7 of different width specifications. This avoids excessive compression deformation or missed processing of the steel strip 7 sides due to horizontal position deviation, thus preventing deformation problems caused by horizontal deviation. Furthermore, it reduces the operation time during specification switching, thereby improving the adaptability of the device to different specifications of steel strips 7, ensuring the stability of processing quality, and improving production efficiency.
[0024] See Figure 3 The frame 1 also includes a support plate 12, one end of which is fixed to the side plate 11, providing a stable support base for the installation and movement of the horizontal adjustment mechanism 4. The horizontal adjustment mechanism 4 also includes a slide 43, in which the hobbing teeth 41 are horizontally arranged and rotatably connected to the slide 43, so that when the hobbing teeth 41 are forming the two sides of the steel strip 7, they can rotate synchronously with the conveying of the steel strip 7, ensuring a smooth hobbing process. One end of the horizontal adjusting rod 42 is connected to the slide 43. The bottom of the slide 43 is provided with a protrusion 431, which protrudes downward. Correspondingly, the support plate 12 is provided with a sliding hole 121, which is set along the horizontal direction. The protrusion 431 can be inserted into the sliding hole 121 and move horizontally within the sliding hole 121. The cooperation between the protrusion 431 and the sliding hole 121 provides guidance for the horizontal movement of the slide 43, ensuring that the slide 43 drives the hobbing gear 41 to adjust its position only in the horizontal direction, avoiding vertical offset or shaking during the adjustment process.
[0025] The horizontal adjusting rod 42 is a lead screw, and the side plate 11 is correspondingly provided with an internal thread. The horizontal adjusting rod 42 meshes with the side plate 11, and one end of the horizontal adjusting rod 42 spirally passes through the side plate 11 and is connected to the connecting plate 432 for transmission. By rotating the horizontal adjusting rod 42, the thread transmission characteristics of the lead screw can be used to drive the slide 43 to move smoothly along the sliding hole 121, thereby achieving precise adjustment of the distance between the hobbing gear 41 and the gap 6.
[0026] See Figure 3The carriage 43 includes a connecting plate 432, an upper limit plate 433 and a lower limit plate 434 disposed at the upper and lower ends of the connecting plate 432. The hobbing gear 41 is detachably rotatably connected between the upper limit plate 433 and the lower limit plate 434. The upper limit plate 433 and the lower limit plate 434 are arranged opposite to each other, jointly limiting the hobbing gear 41 in the vertical direction, which can stably restrict the hobbing gear 41 within a preset rotation space, preventing the hobbing gear 41 from moving up and down when processing the steel strip 7, and ensuring that the position of the hobbing gear 41 abutting against both sides of the steel strip 7 is always accurate. The detachable connection between the upper limit plate 433 and the lower limit plate 434 provides operational convenience for the subsequent maintenance and reuse of the hobbing gear 41. The protrusion 431 is disposed on the lower surface of the lower limiting plate 434 and forms a "T" shape with the lower limiting plate 434. The lower limiting plate 434 abuts against the support plate 12. The "T" shape effectively prevents the protrusion 431 from dislodging from the sliding hole 121 when it moves horizontally within the sliding hole 121. Combined with the abutment between the lower limiting plate 434 and the support plate 12, it can further enhance the stability of the slide 43 during movement, prevent the slide 43 from tilting due to uneven force, and ensure the positional accuracy of the hobbing gear 41 during adjustment.
[0027] The horizontal centerline of the hobbing tooth 41 is higher than the horizontal centerline of the gap 6. This ensures that the processed portion of the steel strip 7 corresponds to the lower part of the horizontal centerline of the hobbing tooth 41. During long-term processing, the lower part of the hobbing tooth 41 in contact with the steel strip 7 will wear due to friction. At this time, the hobbing tooth 41 can be disassembled, its upper and lower surfaces flipped, and then reinstalled between the upper limit plate 433 and the lower limit plate 434. After flipping, the unworn upper part of the hobbing tooth 41 will be precisely aligned with the processed portion of the steel strip 7, allowing for continued hobbing. This structure enables bidirectional reuse of the hobbing tooth 41, significantly extending its service life compared to the prior art where the hobbing tooth 41 needs to be scrapped after wear on only one side, thus reducing the consumable costs and maintenance frequency of the equipment.
[0028] Because the reaction force of the steel strip 7 on the hobbing teeth 41 deviates from the centerline of the hobbing teeth 41, resulting in unilateral unbalanced stress, the horizontal adjustment mechanism 4 further includes a pull plate 44 to ensure that the hobbing teeth 41 do not shift or move under unilateral stress. The pull plate 44 is located below the sliding hole 121, and its upper part has an upward protrusion. The longitudinal section of the pull plate 44 is inverted "T" shaped, allowing the upward protrusion to be inserted into the sliding hole 121. The pull plate 44 has a tensioning hole 441, through which a fastener is connected to the protrusion 431 to lock the carriage 43 onto the support plate 12. When the hobbing teeth 41 are adjusted to a preset position by the horizontal adjustment rod 42, the fastener can pass through the tensioning hole 441 and connect to the protrusion 431, thereby firmly locking the carriage 43 onto the support plate 12. This locking structure can counteract the effect of unilateral unbalanced stress on the hobbing gear 41, prevent the carriage 43 from causing the hobbing gear 41 to shift or move during processing, and ensure that the hobbing gear 41 always maintains precise contact with both sides of the steel strip 7.
[0029] Both the upper roller pressing mechanism 2 and the lower roller pressing mechanism 3 include a connecting shaft 22. The connecting shaft 22 passes horizontally through the upper roller 21 and the lower roller 31, providing through-type support for the upper roller 21 and the lower roller 31. This allows the upper roller 21 and the lower roller 31 to rotate stably around the connecting shaft 22, ensuring that their rotation axes remain parallel. Both ends of the connecting shaft 22 are rotatably connected to the side plate 11. This connection method both limits the axial position of the connecting shaft 22 and ensures that the connecting shaft 22 can rotate flexibly, thereby driving the upper roller 21 and the lower roller 31 to rotate synchronously.
[0030] See Figure 2 and Figure 4The synchronous steel belt gear hobbing device also includes a vertical adjustment mechanism 5, which includes an adjustment plate 51 and a vertical adjustment rod 52. The side plate 11 has a movable groove 111, and the adjustment plate 51 is disposed within the movable groove 111. The movable groove 111 provides precise vertical guidance for the movement of the adjustment plate 51, ensuring that the adjustment plate 51 can only move in the vertical direction and avoiding horizontal deviation during adjustment. The vertical adjustment rod 52 is drively connected to the adjustment plate 51, and the end of the connecting shaft 22 is rotatably connected to the adjustment plate 51. The vertical adjustment rod 52, by rotating, can drive the adjustment plate 51 to move vertically within the groove 511. This ensures that the connecting shaft 22 can rotate normally to drive the upper pressure roller 21 or the lower pressure roller 31 to rotate, and also allows the connecting shaft 22 to adjust its position synchronously with the vertical movement of the adjustment plate 51. When the adjusting plate 51 moves, the connecting shaft 22 can drive the upper pressure roller 21 to move closer to or further away from the lower pressure roller 31, thereby achieving flexible adjustment of the height of the gap 6. Compared with the cumbersome operation of adjusting the gap 6 by disassembling components in the prior art, this structure can complete the adjustment of the gap 6 without disassembly, which not only reduces the operation time, but also avoids the impact on the accuracy of components during disassembly. At the same time, precise control of the gap 6 can ensure that the clamping force of the upper pressure roller 21 and the lower pressure roller 31 on the steel strip 7 is moderate, avoiding excessive deformation of the steel strip 7 due to the gap 6 being too small, or unstable conveying of the steel strip 7 due to the gap 6 being too large, further improving the stability of the gear hobbing 41 processing and the product quality.
[0031] See Figure 5 The movable groove 111 has vertically arranged slide rails 112 on both sides, and the adjusting plate 51 has a sliding groove 511 on its side, into which the slide rails 112 are inserted. The slide rails 112 and the sliding grooves 511 provide dual guiding constraints for the vertical movement of the adjusting plate 51, effectively limiting the horizontal offset and swaying of the adjusting plate 51 during movement, ensuring that the adjusting plate 51 always moves smoothly in the vertical direction. The adjusting plate 51 is rotatably connected to the end of the connecting shaft 22, and its smooth movement can further drive the connecting shaft 22 and the upper pressure roller 21 to accurately adjust their positions, avoiding the tilting of the axes of the upper pressure roller 21 and the lower pressure roller 31 due to the offset of the adjusting plate 51, thereby ensuring that the gap 6 between the upper pressure roller 21 and the lower pressure roller 31 is always uniform.
[0032] The vertical adjustment mechanism 5 also includes an upper adjustment frame 53, which is fixed above the movable slot 111, providing stable installation support and positioning reference for the vertical adjustment rod 52. The vertical adjustment rod 52 passes downward through the upper adjustment frame 53 and is connected to the adjustment plate 51 via a transmission mechanism. The vertical adjustment rod 52 is a lead screw, and the lead screw transmission makes the transmission path of the vertical adjustment rod 52 more stable.
[0033] See Figure 6 This invention also discloses a method for adjusting the tooth rolling 41 of a steel strip 7, which uses the synchronous steel strip tooth rolling device described above to adjust the tooth rolling 41 forming process of the steel strip 7, including the following steps: S01, Initial debugging preparation: Align one end of the steel strip 7 to be processed with the gap 6 between the upper pressure roller 21 and the lower pressure roller 31 to ensure that the initial position of the steel strip 7 is aligned with the center line of the device. S02, Horizontal position adjustment: Rotate the horizontal adjustment rods 42 of the two horizontal adjustment mechanisms 4 to drive the slide 43 to move horizontally along the sliding hole 121 of the support plate 12, thereby adjusting the distance between the hobbing teeth 41 and the gap 6, so that the hobbing teeth 41 on both sides abut against the two side edges of the steel strip 7, until the hobbing teeth 41 fit against the side of the steel strip 7. S03, Position locking: The slide 43 is locked onto the support plate 12 by fasteners passing through the tension hole 441 of the pull plate 44 and connecting to the protrusion 431 of the lower limit plate 434 of the slide 43. S04, Vertical gap 6 adjustment: Rotate the vertical adjustment rod 52 of the vertical adjustment mechanism 5 to drive the adjustment plate 51 to move vertically along the movable groove 111 of the side plate 11, thereby driving the upper pressure roller 21 to move closer to or further away from the lower pressure roller 31, and adjusting the gap 6 between the upper pressure roller 21 and the lower pressure roller 31 so that the height of the gap 6 is adapted to the thickness of the steel strip 7. S05, Trial run verification: Start the device to transport the steel belt 7 along the gap 6, check whether the forming of the hobbing teeth 41 on the side of the steel belt 7 is qualified, and check whether the center line of the steel belt 7 is deviated during the transport process.
[0034] During the initial debugging and preparation phase, one end of the steel strip 7 to be processed is aligned with the gap 6 between the upper pressure roller 21 and the lower pressure roller 31 to ensure that the initial position of the steel strip 7 is aligned with the center line of the device. This step provides a reference for all subsequent adjustment operations, avoiding cumulative errors in subsequent horizontal and vertical adjustments due to the initial offset of the steel strip 7, and solving the problem in the prior art that neglecting initial alignment and directly starting processing can easily lead to overall gear hobbing 41 accuracy deviation.
[0035] Entering the horizontal position adjustment stage, the horizontal adjustment rods 42 of the two horizontal adjustment mechanisms 4 are rotated. Through the transmission action of the horizontal adjustment rods 42, the slide 43 is driven to move horizontally along the sliding holes 121 of the support plate 12, thereby adjusting the distance between the hobbing teeth 41 and the gap 6 until the hobbing teeth 41 on both sides abut against and fit against the sides of the steel strip 7. During this process, the sliding holes 121 provide guidance for the movement of the slide 43, ensuring that the hobbing teeth 41 are adjusted only in the horizontal direction, avoiding vertical offset. Through the adjustment of the horizontal adjustment rods 42, the hobbing teeth 41 can flexibly adapt to steel strips 7 of different widths, solving the problem in the prior art where the hobbing teeth 41 are fixed and cannot fit against the sides of steel strips 7 of different widths, ensuring uniform contact between the hobbing teeth 41 and the sides of the steel strip 7 during subsequent hobbing tooth forming.
[0036] After horizontal position adjustment is completed, position locking is performed. The fastener passes through the tension hole 441 of the pull plate 44 and connects to the protrusion 431 of the lower limit plate 434 of the carriage 43, locking the carriage 43 onto the support plate 12. This locking structure utilizes the fastening force of the fastener to form a stable connection between the carriage 43 and the support plate 12, which can counteract the unilateral unbalanced stress generated by the reaction force of the steel strip 7 on the hobbing gear 41, preventing the carriage 43 from shifting or moving during the conveying of the steel strip 7 and the processing of the hobbing gear 41.
[0037] During the horizontal position adjustment, the vertical gap 6 can be adjusted simultaneously. Rotating the vertical adjustment rod 52 of the vertical adjustment mechanism 5 drives the adjustment plate 51 to move vertically along the movable groove 111 of the side plate 11. The movement of the adjustment plate 51 causes the connecting shaft 22 to move vertically synchronously, thereby moving the upper pressure roller 21 closer to or further away from the lower pressure roller 31. This adjusts the gap 6 between the upper pressure roller 21 and the lower pressure roller 31, ensuring that the height of the gap 6 matches the thickness of the steel strip 7. Through fine-tuning of the vertical adjustment rod 52, the gap 6 can be precisely matched to steel strips 7 of different thicknesses, solving the problem in the prior art where the gap 6 is fixed and cannot adapt to steel strips 7 of various thicknesses. This ensures that the steel strip 7 is stably clamped during conveying and is not easily deformed due to improper gap 6.
[0038] Finally, a trial run was conducted for verification. The device was started to convey the steel strip 7 along the gap 6. During this process, the quality of the forming of the hobbing teeth 41 on the side of the steel strip 7 was checked, and the centerline of the steel strip 7 was also checked for deviation. By simulating the actual processing scenario, hidden problems such as uneven forming depth of the hobbing teeth 41, insufficient tooth profile accuracy, or deviation of the centerline of the steel strip 7 can be detected in real time. This allows for timely return to previous steps for secondary adjustments, avoiding direct entry into batch processing and the generation of a large number of defective products.
[0039] The method for adjusting the steel strip 7 hobbing gear 41 also includes the following steps: During the hobbing process of steel strip 7, a laser alignment instrument is used to monitor the centerline position and parallelism of steel strip 7. If the centerline offset is detected to exceed the centerline error value, the device operation is paused, the fasteners on the pull plate 44 are loosened, and the horizontal adjustment rod 42 is rotated to adjust the horizontal position of the slide 43. If the parallelism error is detected to exceed the parallelism error value, the device operation is paused, and the vertical adjustment rod 52 is rotated to adjust the vertical position of the upper pressure roller 21.
[0040] During the continuous processing of the steel strip 7 by the hobbing gear 41, the laser alignment instrument is introduced to monitor the centerline position and parallelism of the steel strip 7 in real time. The laser alignment instrument has the advantages of high precision and real-time monitoring, and can continuously capture subtle positional changes of the steel strip 7 during the conveying process, providing accurate data for subsequent deviation correction. When the laser alignment instrument detects that the centerline deviation of the steel strip 7 exceeds the preset centerline error value (e.g., 0.03mm), the operation of the device is immediately paused. At this time, the fasteners on the pull plate 44 are loosened first, releasing the locking state between the slide 43 and the support plate 12; then the horizontal adjustment rod 42 of the horizontal adjustment mechanism 4 is rotated, and the slide 43 is driven to move horizontally along the sliding hole 121 of the support plate 12 through the transmission action of the horizontal adjustment rod 42, thereby driving the hobbing gear 41 to synchronously fine-tune its position. Since the hobbing teeth 41 abut against the two side edges of the steel strip 7, the fine adjustment of the hobbing teeth 41 can indirectly pull the centerline of the steel strip 7 back to the reference position until the laser alignment instrument detects that the centerline deviation of the steel strip 7 has returned to the centerline error range (≤0.03mm). This operation can quickly correct the centerline deviation without disassembling the core components of the device, solving the problems of needing to stop the machine for disassembly and assembly and low adjustment efficiency in the prior art after the centerline deviation. At the same time, it ensures that the hobbing teeth 41 can still accurately fit the side of the steel strip 7 after correction, avoiding new hobbing tooth 41 forming deviation caused by the correction operation.
[0041] If the laser alignment instrument detects that the parallelism error of the steel strip 7 exceeds a preset parallelism error value (e.g., 0.05mm), the operation of the device is also paused. At this time, the vertical adjustment rod 52 of the vertical adjustment mechanism 5 is directly rotated. Through the transmission cooperation between the vertical adjustment rod 52 and the adjustment plate 51, the adjustment plate 51 is driven to move vertically along the movable groove 111 of the side plate 11. Since the end of the connecting shaft 22 is rotatably connected to the adjustment plate 51, the movement of the adjustment plate 51 will drive the upper pressure roller 21 to make a synchronous vertical position fine adjustment, thereby adjusting the uniformity of the gap 6 between the upper pressure roller 21 and the lower pressure roller 31. By fine-tuning the vertical position of the upper pressure roller 21, the parallelism of the axes of the upper pressure roller 21 and the lower pressure roller 31 can be corrected, so that the axes of the two remain precisely parallel, until the laser alignment instrument detects that the parallelism error of the steel strip 7 has fallen back to the parallelism error value range (≤0.05mm).
[0042] The method for adjusting the steel strip 7 hobbing gear 41 also includes the following steps: When the actual width of the steel strip 7 to be processed deviates from the width of the steel strip 7 processed in the previous batch by a greater than or equal to the width deviation value, loosen the fastener on the pull plate 44, and rotate the horizontal adjustment rod 42 again to increase or decrease the spacing between the two sides of the hobbing teeth 41, and make the contact gap 6 between the hobbing teeth 41 and the side of the steel strip 7 less than or equal to the maximum allowable gap 6, and the contact pressure of the hobbing teeth 41 on the side of the steel strip 7 is stably maintained within the first preset pressure range; When the actual thickness of the steel strip 7 to be processed deviates from the thickness of the steel strip 7 processed in the previous batch by a greater or equal thickness deviation value, the vertical adjustment rod 52 is rotated again to increase or decrease the height of the gap 6, and the contact pressure of the upper pressure roller 21 and the lower pressure roller 31 on the surface of the steel strip 7 is stably maintained within the second preset pressure range. When wear occurs at the part of the hobbing tooth 41 that contacts the steel strip 7, the hobbing tooth 41 is disassembled, the upper and lower sides of the hobbing tooth 41 are reversed, and then the hobbing tooth 41 is installed into the carriage 43 so that the unworn part abuts against the side of the steel strip 7.
[0043] During the processing of the steel strip 7 by the hobbing teeth 41, when switching between different batches of the steel strip 7 to be processed, the actual width of the steel strip 7 to be processed must first be compared with the width of the steel strip 7 processed in the previous batch. If the width deviation is detected to be greater than or equal to the width deviation value (0.5mm-1.2mm), the fasteners on the pull plate 44 are loosened to release the locking state of the slide 43. Then, the horizontal adjustment rod 42 of the horizontal adjustment mechanism 4 is rotated again, and the slide 43 is driven to move horizontally along the sliding hole 121 of the support plate 12 through the horizontal adjustment rod 42, thereby increasing or decreasing the distance between the hobbing teeth 41 on both sides.
[0044] During adjustment, the contact gap 6 between the hobbing teeth 41 and the side of the steel strip 7 must be less than or equal to the maximum allowable gap 6. Simultaneously, the contact pressure of the hobbing teeth 41 against the side of the steel strip 7 is stably maintained within a first preset pressure range by controlling the adjustment force of the horizontal adjusting rod 42. For thin steel strips 7, the pressure can be controlled at 15-22N to avoid side deformation; for thick steel strips 7, the pressure can be increased to 20-28N to ensure the forming depth of the hobbing teeth 41. This operation solves the problem in the prior art where the hobbing teeth 41 have a fixed spacing and cannot adapt to steel strips 7 with different width deviations, ensuring that steel strips 7 of different widths can accurately fit with the hobbing teeth 41, guaranteeing the consistency of the hobbing teeth 41 forming.
[0045] When comparing the actual thickness of the steel strip 7 to be processed with the thickness of the steel strip 7 processed in the previous batch, if the thickness deviation is detected to be greater than or equal to the thickness deviation value (0.2mm-0.8mm), then there is no need to disassemble other components; the vertical adjustment rod 52 of the vertical adjustment mechanism 5 can be directly rotated again. The vertical adjustment rod 52 drives the adjustment plate 51 to move vertically along the movable groove 111 of the side plate 11, causing the upper pressure roller 21 to move closer to or further away from the lower pressure roller 31, thereby increasing or decreasing the height of the gap 6 between the upper pressure roller 21 and the lower pressure roller 31.
[0046] Simultaneously, the contact pressure between the upper pressure roller 21 and the lower pressure roller 31 on the surface of the steel strip 7 needs to be stably maintained within the second preset pressure range by controlling the adjustment force of the vertical adjustment rod 52. For thin steel strips 7, the pressure is controlled at 30-40N to avoid surface depression; for thick steel strips 7, the pressure is increased to 40-55N to ensure stable clamping and prevent the steel strip 7 from shifting during conveying. This adjustment method solves the problem in the prior art where the gap 6 is fixed and cannot adapt to steel strips 7 with different thickness deviations, ensuring that steel strips 7 of different thicknesses can be stably clamped and are not easily deformed due to improper pressure.
[0047] During long-term processing, the part of the hobbing gear 41 that contacts the steel strip 7 will wear due to continuous friction. Since the reaction force of the steel strip 7 on the hobbing gear 41 is located at the lower part of the hobbing gear 41, the initial damage location of the hobbing gear 41 is at the lower part. At this time, it is not necessary to replace the hobbing gear 41 with a brand new one. Simply disassemble the hobbing gear 41, then reverse its upper and lower sides so that the originally unworn upper area faces downward. Then, reinstall the reversed hobbing gear 41 between the upper limit plate 433 and the lower limit plate 434 of the carriage 43, ensuring that the unworn part can abut against the side of the steel strip 7. This achieves bidirectional reuse of the hobbing gear 41, solving the problem in the prior art that the hobbing gear 41 needs to be scrapped after wear on only one side, greatly extending the service life of the hobbing gear 41, while reducing consumable replacement costs and downtime maintenance time, and improving processing efficiency.
[0048] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
