Technical Field

[0001] This utility model relates to the field of tension leveling roller technology, specifically to a tension leveling roller structure for a tension leveling machine used in strip steel production. Background Technology

[0002] A sheet metal straightening machine is a device used for straightening metal sheets and profiles, and is widely used in industries such as strip steel and non-ferrous metals. Its main function is to eliminate surface irregularities, waviness, wavy lines, warping, and slight camber in materials through stretching and bending, thereby significantly improving the straightness of the materials.

[0003] The straightening operation of the tension leveler is mainly achieved through tension leveling rollers. However, in the traditional technology, tension leveling rollers lack effective material limiting measures. After the material comes into contact with the tension leveling rollers, the material is prone to deviating, making it difficult to guarantee the tension leveling quality of the material.

[0004] Based on this, we propose a tension roller structure for a tension leveling machine used in strip steel production. Utility Model Content

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-5 As shown, this embodiment proposes a straightening roller structure for a strip steel production straightening machine, including a hollow rotating shaft 1. A straightening ring 2 is fixedly connected to the outer side of the hollow rotating shaft 1. Displacement plates 3 are slidably connected to both ends inside the hollow rotating shaft 1. Multiple push seats 4 are fixedly connected to the outer side of the displacement plates 3. The outer side of both ends of the hollow rotating shaft 1 is provided with relief grooves 5 corresponding to the push seats 4. The push seats 4 are also slidably connected inside the corresponding relief grooves 5. A transmission component is provided inside the hollow rotating shaft 1. The transmission component is used to drive the two displacement plates 3 to move. A positioning plate 6 is fixedly connected to the end of the push seat 4 away from the displacement plate 3. A limit component 7 is provided on the positioning plate 6. The limit component 7 is used to cooperate with the positioning plate 6 to form a lateral limit of the strip steel.

[0027] The transmission assembly includes a transmission rack 8, a linkage shaft 9, and a linkage spur gear 10. The two displacement plates 3 are fixedly connected to the ends of each other. The linkage shaft 9 is rotatably connected to the middle of the hollow shaft 1. The linkage spur gear 10 is fixedly connected to the middle of the linkage shaft 9. The two transmission racks 8 are respectively meshed and connected to the two ends of the linkage spur gear 10. A locking plate 11 is fixedly connected to one end of the hollow shaft 1. A locking groove 12 is opened on one side of the locking plate 11. A limit pin 13 is fixedly connected to one side of one of the push seats 4 corresponding to the locking plate 11. One end of the limit pin 13 passes through the locking groove 12. A threaded section 14 is opened on the outer end of the limit pin 13. A locking piece 15 is threadedly connected to the threaded section 14.

[0028] In this embodiment, a support hole is provided in the middle of the inner side of the hollow rotating shaft 1. The linkage rotating shaft 9 is connected to the inside of the support hole through a ball bearing. The support hole enables the linkage rotating shaft 9 to be effectively assembled. In addition, the ball bearing effectively improves the smoothness of the rotation of the linkage rotating shaft 9 and reduces wear.

[0029] In this embodiment, protective pads are fixedly connected to the sides of the locking groove 12 and the locking piece 15 that are close to each other, and anti-slip textures are provided on the protective pads. By setting the protective pads, the friction force when the locking groove 12 and the locking piece 15 come into contact can be increased, and uncontrollable displacement of the push seat 4 can be avoided.

[0030] Example 2

[0031] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a limiting component 7;

[0032] In this embodiment, the limiting component 7 includes a limiting plate 16, a positioning seat 17, a positioning shaft 18, and a positioning frame 19. The two ends of one side of the positioning disk 6 are slidably connected to the limiting plate 16, and the two ends of the other side of the positioning disk 6 are fixedly connected to the positioning seat 17. The positioning shaft 18 is rotatably connected to the inner side of the positioning seat 17, and the positioning frame 19 is fixedly connected to the positioning shaft 18. The top end of the positioning shaft 18 is threaded with an anti-rotation screw 20.

[0033] In this embodiment, both ends of one side of the positioning disk 6 are provided with linear slide grooves, and one side of the limiting plate 16 is fixedly connected with a linear slide rail. The limiting plate 16 is connected to the inside of the linear slide groove through the linear slide rail. By setting the linear slide groove, when the positioning disk 6 and the limiting plate 16 are assembled, the linear slide rail is first aligned with the linear slide groove, and the limiting plate 16 is pushed. When the linear slide rail reaches the end of the linear slide groove, the limiting plate 16 can be installed in the predetermined position.

[0034] In this embodiment, a plurality of alloy balls are provided at the end of the limiting plate 16 away from the linear slide rail. By setting the alloy balls, the lateral limiting of the strip can be achieved by the limiting plate 16, while also reducing the wear between the limiting plate 16 and the strip.

[0035] In this embodiment, the limiting plate 16 has an arc-shaped structure, and a noise reduction strip is provided at the connection between the two limiting plates 16. Due to the structural characteristics of the limiting plate 16, a complete ring can be formed when the two limiting plates 16 come into contact with each other.

[0036] A specific application of the above two embodiments is that pushing any one of the push seats 4 causes the displacement piece 3 to move inside the hollow rotating shaft 1, and pushes the positioning disk 6 to adjust outside the hollow rotating shaft 1. In conjunction with the connection between the transmission rack 8 and the displacement piece 3, when the displacement piece 3 moves, it can use the transmission rack 8 to move the linkage spur gear 10. Since both transmission racks 8 are meshed with the linkage spur gear 10, the linkage spur gear 10 can then move another transmission rack 8, causing the two displacement pieces 3 to move towards each other, and causing the two positioning disks 6 to move closer to each other. The distance between the two positioning disks 6 is the tensioning width of the strip steel. After adjustment, rotating the locking piece 15 causes the locking piece 15 to move on the threaded section 14 until the locking piece 15 is tightly fitted with the locking through groove 12, thereby increasing the friction when the push seat 4 moves, and finally locking the position of the positioning disk 6.

[0037] During straightening, the lateral movement of the strip can be limited by the limiting plate 16 to prevent the strip from deviating. When the limiting plate 16 is severely worn, the anti-rotation screw 20 can be loosened to move the anti-rotation screw 20 away from the positioning seat 17, thereby reducing the friction when the positioning shaft 18 rotates. Then, the positioning frame 19 can be pulled away from the limiting plate 16. Finally, the limiting plate 16 can be removed from the positioning plate 6 and replaced.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
