Description

Technical Field

[0001] This utility model relates to the field of pipe rolling technology, and in particular to a steel strip straightening device for pipe rolling production. Background Technology

[0002] As the core raw material for pipe coiling, steel strip may develop defects such as bending, wavy shape, or edge curling during transportation, storage, or processing. To solve this problem, a steel strip straightening device for pipe coiling is usually used. This device uses multiple sets of leveling rollers in different directions to repeatedly roll the steel strip, eliminating internal stress by utilizing the principle of reverse elastic deformation.

[0003] Existing straightening devices typically involve physically limiting the edges of the steel belt after it enters the device using a set of guide wheels (with arc grooves) to prevent it from shifting left or right during transport. Then, as the steel belt passes through the pressure rollers, the upper and lower rollers apply reverse pressure to it, causing the steel belt to undergo elastic deformation of "bending first and then recovering," thereby releasing internal stress and eliminating defects such as wavy shapes and local bulges.

[0004] Considering that various specifications of rolled tubes are typically produced during tube rolling, and that the core raw material for tube rolling production also varies in width and thickness depending on the specifications, the pressure rollers used to straighten the edges of the steel strip need to be height-adjusted to accommodate steel strips of different widths. However, existing straightening devices often use a single-group independent adjustment mode for the pressure roller height, requiring the use of wrenches and other tools to tighten the fixing bolts of each roller individually to adjust the height. This adjustment mode is not only cumbersome and repetitive, but also consumes a significant amount of manual time for each specification change, severely slowing down the production pace. More importantly, individual group adjustments are prone to inconsistent roller heights due to human error, resulting in uneven force on the steel strip as it passes through, leading to straightening accuracy problems such as edge warping and central depression. Therefore, a steel strip straightening device for tube rolling production is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a steel strip straightening device for tube rolling production. It aims to solve the problem that in existing technologies, tube rolling requires the production of various specifications of rolled tubes, and the width and thickness of the core raw material, steel strip, vary with the specifications. Adjusting the height of the pressure rollers is necessary to adapt to different widths of steel strips. Currently, most methods involve independent adjustment of a single group, requiring tools to tighten the fixing bolts of each pressure roller individually. This method is cumbersome and repetitive, and each specification change is time-consuming, slowing down the production pace. More importantly, individual group adjustments are prone to human error, leading to inconsistent heights of multiple pressure rollers, resulting in uneven stress on the steel strip and precision problems such as edge warping and central depressions.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a steel strip straightening device for tube rolling production, including a support platform 1. The support platform 1 provides a supporting foundation for the entire device, enabling stable installation of each component. A ring 7 is fixedly connected to the center of the outer surface of the support platform 1 via a column 11. The column 11 is used to fix the ring 7, providing an installation support point for the ring 7 and ensuring the stability of the ring 7's position. A connecting rod 14 is slidably connected through the outer surface of the column 11. The connecting rod 14 can slide along the column 11 to drive the pressure roller 6 to adjust its position, adapting to the straightening requirements of steel strips of different widths. The pressure roller 6 is rotatably connected through the outer surface of the connecting rod 14. When the steel strip passes through the pressure roller 6, the pressure roller 6 applies reverse pressure to it, and then the edge of the steel strip is leveled through rotation. A traction ring 9 is fixedly connected to the outer surface of the connecting rod 14. The traction ring 9 is used to link multiple sets of connecting rods 14, enabling multiple sets of connecting rods 14 to adjust their positions synchronously, ensuring the consistency of adjustment of multiple sets of pressure rollers 6.

[0033] Reference Figures 2-3An adjustment component 10 is provided on the outer surface of the traction ring 9. The adjustment component 10 is used to adjust the vertical position of the traction ring 9, thereby driving multiple sets of pressure rollers 6 to adjust synchronously. The adjustment component 10 includes a threaded sleeve 102, which is fixed to the traction ring 9 and provides a threaded connection structure for the threaded column 101. Through the threaded engagement, the rotation of the threaded column 101 is converted into the vertical movement of the traction ring 9. The outer surface of the threaded sleeve 102 is fixedly connected to the inner surface of the traction ring 9 to ensure that the threaded sleeve 102 and the traction ring 9 move synchronously and to ensure the effective transmission of adjustment force. The inner surface of the threaded sleeve 102 is penetrated and threadedly connected to the threaded column 101. The threaded column 101 converts its own rotation into the vertical displacement of the traction ring 9 through the threaded action with the threaded sleeve 102. The bottom of the outer surface of the threaded column 101 is rotatably connected to the middle of the outer surface of the bearing platform 1, so that the threaded column 101 can rotate stably and provide power support for the adjustment of the traction ring 9.

[0034] Reference Figures 3-4 A limiting component 13 is provided on the outer surface of the traction ring 9. The limiting component 13 is used to fix the vertical position of the traction ring 9 to prevent it from shifting position during the correction process. The limiting component 13 includes a limiting strip 131, which is used to transmit the displacement of the traction ring 9 and cooperate with the wedge block 132 to achieve limiting. The bottom end of the outer surface of the limiting strip 131 is fixedly connected to the top end of the outer surface of the traction ring 9, so that the limiting strip 131 moves synchronously with the traction ring 9 to ensure that the limiting position corresponds to the position of the traction ring 9. The top end of the outer surface of the limiting strip 131 penetrates and slides through the inner surface of the ring 7 to provide guidance for the movement of the traction ring 9 and ensure the stability of the vertical movement of the traction ring 9.

[0035] Reference Figures 3-4 A threaded seat 134 is fixedly connected to the top of the outer surface of the ring 7. The threaded seat 134 is used to fix and install the bolt 133, providing a basic structure for the threaded connection of the bolt 133. The inner surface of the threaded seat 134 is threaded through and connected to the bolt 133. The bolt 133 can drive the wedge 132 to slide along the threaded seat 134 when it rotates through the threaded connection with the threaded seat 134. The outer surface of the bolt 133 is rotatably connected to the wedge 132. The wedge 132 can move with the bolt 133 and be inserted into the limiting strip 131 to achieve limiting fixation. The outer surface of the wedge 132 is slidably connected to the top of the outer surface of the threaded seat 134 to ensure that the wedge 132 moves in a straight line and is accurately inserted into the limiting strip 131. The outer surface of the wedge 132 is inserted into the inner surface of the limiting strip 131. When the wedge 132 is inserted into the limiting strip 131, it restricts the movement of the limiting strip 131, thereby fixing the position of the traction ring 9.

[0036] Reference Figure 1The outer surface of the support platform 1 is provided with a guide assembly 2, which is used to guide the steel strip entering the device so that the steel strip can accurately enter the correction area. The guide assembly 2 includes a rod 201, which is used for fixed connection and provides a sliding guide structure for the fixed column 202 to ensure the sliding stability of the fixed column 202. The bottom end of the outer surface of the rod 201 is fixedly connected to the top end of the outer surface of the ring 7 and the top end of the outer surface of the support platform 1, which enhances the installation stability of the rod 201 and ensures that the overall structure of the guide assembly 2 is solid. The inner surface of the rod 201 is slidably connected to the fixed column. 202. The fixed column 202 can slide along the rod 201 to drive the guide plate 203 to adjust its position to adapt to steel strips of different widths. The guide plate 203 is fixedly connected to the bottom of the outer surface of the fixed column 202. The guide plate 203 directly contacts the steel strip to limit and guide the steel strip. The left side of the guide plate 203 is raised to facilitate the smooth sliding of the steel strip into the guide area and reduce the resistance when the steel strip enters. There are four sets of guide plates 203, which are evenly wrapped around the inner surface of the bearing platform 1. They can limit and guide the steel strip from multiple directions to ensure the accurate position of the steel strip when it enters, which is convenient for subsequent correction.

[0037] Reference Figures 1-3 A tension roller 5 is rotatably connected to the bottom of the outer surface of the ring 7. The tension roller 5 applies outward tension to the steel strip to help flatten it. An auxiliary roller 4 is rotatably connected to the middle of the inner surface of the support platform 1. The auxiliary roller 4 is used to provide auxiliary support for the steel strip, so that the steel strip remains stable during the straightening process and facilitates the straightening operation. A discharge roller 12 is rotatably connected to the middle of the outer surface of the support platform 1. The discharge roller 12 is used to discharge the straightened steel strip from the device. Its rotational characteristics can reduce frictional damage to the surface of the steel strip. The discharge roller 12 is set in an inclined shape to facilitate the smooth guidance of the steel strip to the coiling processing area for subsequent collection or processing. A feed groove 3 is opened on the right side of the outer surface of the support platform 1. The feed groove 3 is used to provide a channel for the steel strip to enter the device, so that the steel strip can smoothly enter the inside of the support platform 1 from the right side for straightening.

[0038] Reference Figures 1-3 A guide post 8 is fixedly connected to the middle of the inner surface of the bearing platform 1. The guide post 8 provides guidance for the vertical movement of the traction ring 9, ensuring the straightness of the traction ring 9 when it moves. The inner surface of the traction ring 9 penetrates and slides through the outer surface of the guide post 8, so that the traction ring 9 moves stably along the guide post 8. This ensures that multiple sets of connecting rods 14 and pressure rollers 6 are adjusted synchronously and smoothly. Multiple sets of auxiliary rollers 4, tension rollers 5 and pressure rollers 6 are provided and are evenly wrapped around the middle of the inner surface of the bearing platform 1. Multiple sets of components support and correct the steel strip from multiple angles, improving the correction effect and uniformity, and adapting to the correction needs of steel strips of different widths and shapes.

[0039] Working principle: When changing the width of the steel strip being corrected, the bolt 133 is first pushed outward, causing the bolt 133 to disengage the wedge 132 from the inside of the limiting strip 131, thereby releasing the vertical limit on the traction ring 9. Then, the threaded column 101 is rotated, so that it is connected to the threaded sleeve 102 on the traction ring 9, thereby driving the traction ring 9 to move vertically. At the same time, multiple sets of connecting rods 14 are driven to move vertically along the surface of multiple sets of columns 11 at the bottom of the ring 7, allowing multiple sets of connecting rods 14 to drive multiple sets of pressure rollers 6 to move vertically to adapt to steel strips of different widths. After the adjustment is completed, the bolt 133 is screwed inward, causing the wedge 132 to engage with the inside of the limiting strip 131, thereby fixing the height of the traction ring 9.
