Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a driving mechanism for a support roller of a cold rolling mill. Background Art

[0002] At present, the main machines of cold rolling mills and foil rolling mills for metals such as aluminum alloys, steel strips and copper alloys are mainly divided into two types, one is a four-roll mill (driven by working rolls) and the other is a six-roll mill (driven by intermediate rolls). Whether it is a four-roll mill or a six-roll mill, the upper and lower rolls acting on the rolled products are driven by a group of single or multiple motors: the motor group is connected to the reducer through a coupling, and then drives the upper and lower rolls simultaneously through a universal coupling and a split gear box. The reducer is connected to the split gear box through a coupling, and then the split gear box is connected to the upper and lower rolls through two universal couplings, respectively, to provide power for the upper and lower rolls, so that the upper and lower rolls maintain the same rotational angular velocity to ensure that the upper and lower rolls have the same speed. The existing cold rolling mill support roller drive mechanism is connected to the support roller through a coupling. During operation, the two ends of the coupling are fixed, while the middle part is in a suspended state, which may cause the coupling to deform during operation, thereby affecting the performance and life of the entire drive mechanism. Utility Model Content

[0003] Based on this, the purpose of the utility model is to provide a driving mechanism for the support rollers of a cold rolling mill to solve the technical problem that the middle part is in a suspended state, which may cause the coupling to deform during operation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a driving mechanism for a cold rolling mill support roller, comprising a gearbox, a cross coupling is fixedly connected to one side of the gearbox, a first support mechanism is arranged below the cross coupling, the first support mechanism comprises a first bottom plate, the first bottom plate, a first support rod is fixedly connected to one side of the top of the first bottom plate, a first inner rod is slidably connected to the top of the first support rod, and a first upper support platform is fixedly connected to the top of the first inner rod;

[0005] The top end of the first support rod is connected with an adjusting ring through a thread, the adjusting ring is provided with a groove, a first buffer spring is arranged inside the groove, and the top end of the first buffer spring is in conflict with the first upper support platform.

[0006] By adopting the above technical solution, the first upper support platform in the first support mechanism is connected to the adjustment ring through the first buffer spring, so that the support platform can support the cross coupling with different elasticities as needed, effectively reducing the vibration and impact during the operation of the coupling.

[0007] Furthermore, an arc-shaped groove is formed on the upper support platform, and a rolling ball is engaged on the inner wall of the arc-shaped groove.

[0008] By adopting the above technical solution, the arc groove opened on the upper support platform is combined with the ball engaged therein to form a support surface that can effectively reduce friction. When the cross coupling is running, its outer surface contacts the ball. Since the ball can roll freely, the original sliding friction is converted into rolling friction, which greatly reduces the friction resistance.

[0009] Furthermore, two second buffer springs are fixedly connected to the other side of the top of the first bottom plate, and the top ends of the two second buffer springs are fixedly connected to the first lower support platform, and the inner wall of the first lower support platform is engaged with the rolling ball.

[0010] By adopting the above technical solution, by arranging two second buffer springs and the first lower support platform on the other side of the top of the first base plate, additional support points are provided for the cross coupling, so that during the operation of the cross coupling, not only the upper cross coupling is stably supported, but the lower cross coupling also has corresponding buffer and support structures, thereby ensuring the overall stability of the coupling mechanism.

[0011] Furthermore, a plurality of the rolling balls are provided, and the plurality of the rolling balls are arranged equidistantly in a ring shape.

[0012] By adopting the above technical solution, by setting up multiple rolling balls and arranging them equidistantly in a ring, it is ensured that the support for the cross coupling is all-round and uniform, avoiding stress concentration and imbalance that may be caused by single-point support, thereby improving the stability and reliability of the support.

[0013] Furthermore, a second supporting mechanism is provided below the cross coupling, and the second supporting mechanism includes a second bottom plate.

[0014] By adopting the above technical solution, the existence of the second supporting mechanism provides another supporting method for the cross coupling, thereby effectively adapting to the angle of the coupling during the tilting operation and enhancing the supporting stability of the cross coupling.

[0015] Furthermore, both sides of the second bottom plate are fixedly connected with a third buffer spring group, and the top end of the third buffer spring group is fixedly connected with a second lower support platform.

[0016] By adopting the above technical solution, by fixing the third buffer spring group on both sides of the second base plate, a support with buffering function is provided for the cross coupling, so that when the cross coupling below is subjected to external impact or vibration, the third buffer spring group can absorb and disperse these forces, thereby reducing direct damage to the coupling.

[0017] Furthermore, a second support rod is arranged between the two third buffer spring groups, and the top end of the second support rod is slidably connected to a second inner rod.

[0018] By adopting the above technical solution, the second inner rod slidably connected to the top of the second support rod provides flexibility for the support structure, allowing the second inner rod to slide up and down to a certain extent inside the second support rod to adapt to the vertical displacement that may occur in the cross coupling during operation.

[0019] Furthermore, two of the second support rods and the second inner rods are provided, and a balance plate is rotatably connected between the two second inner rods.

[0020] By adopting the above technical solution, the balance plate can rotate freely between the two second inner rods, so that it can be adjusted according to the real-time position and angle of the cross coupling, thereby always maintaining stable support for the coupling.

[0021] Furthermore, the two sides of the balance board are rotatably connected with second upper support platforms, and the interiors of the two second upper support platforms are engaged with the rolling balls.

[0022] By adopting the above technical solution, by rotatably connecting the second upper support platforms on both sides of the balance plate and ensuring that the insides of the two second upper support platforms are engaged with the rolling balls, a more precise and stable support is provided for the cross coupling.

[0023] Furthermore, the top end of the second support rod is threadedly connected to the adjustment ring, and a fourth buffer spring is arranged inside the groove.

[0024] By adopting the above technical solution, by threading the top end of the second support rod with the adjustment ring, the function of fine-tuning the support elasticity is achieved, so that the staff can accurately adjust the support force by rotating the adjustment ring as needed, effectively improving the adaptability of the support.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model sets a first support mechanism, and the rotating adjustment ring can accurately adjust the support force of the first buffer spring on the first upper support platform. The existence of the first lower support platform further improves the support system, provides solid support for the coupling below, ensures that the cross coupling can be stably supported during operation, improves the stability and balance of the equipment operation, and effectively prevents problems such as vibration, deviation or wear caused by insufficient support;

[0027] 2. The utility model introduces a rolling contact surface between the cross coupling and the support table by setting the rolling ball, thereby reducing the friction force, thereby greatly reducing the friction resistance, improving the mechanical efficiency, and protecting the key components from unnecessary damage;

[0028] 3. The utility model realizes dynamic balancing support for the cross coupling by setting up a second supporting mechanism. By utilizing the balance plate that can rotate freely and the two second lower supporting platforms, the supporting platforms on both sides can be adaptively adjusted according to the real-time angle of the cross coupling, ensuring that no matter how the angle of the cross coupling changes, the supporting platforms can always provide it with stable and reliable support.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A driving mechanism for a cold rolling mill support roller, such as Figure 1-Figure 4 As shown, it includes a gearbox 1, a cross coupling 2 is fixedly connected to one side of the gearbox 1, a first supporting mechanism 3 is arranged below the cross coupling 2, and the first supporting mechanism 3 includes a first bottom plate 301, the first bottom plate 301, a first supporting rod 302 is fixedly connected to one side of the top of the first bottom plate 301, a first inner rod 303 is slidably connected to the top of the first supporting rod 302, and a first upper supporting platform 304 is fixedly connected to the top of the first inner rod 303;

[0038] The top of the first support rod 302 is connected to an adjusting ring 306 via a thread 305, and a groove 307 is provided on the adjusting ring 306. A first buffer spring 308 is arranged inside the groove 307. The top of the first buffer spring 308 is in conflict with the first upper support platform 304. The first upper support platform 304 in the first support mechanism 3 is connected to the adjusting ring 306 via the first buffer spring 308, so that the support platform 304 can support the cross coupling 2 with different elasticities as needed, effectively reducing the vibration and impact during the operation of the coupling. At the same time, the adjusting ring 306 is connected to the first support rod 302 via a thread 305. The compression degree of the first buffer spring 308 can be accurately adjusted by rotating the adjusting ring 306, thereby controlling the size of the supporting force. This is not only convenient for installation and maintenance, but also can flexibly adjust the stiffness of the support mechanism under different working conditions to meet different support requirements.

[0039] See also Figure 1 , Figure 2 and Figure 3 An arc groove 309 is provided on the upper support platform 304, and a ball 310 is engaged with the inner wall of the arc groove 309. The arc groove 309 provided on the upper support platform 304 is combined with the ball 310 engaged therein to form a support surface that can effectively reduce friction. When the cross coupling 2 is in operation, its outer surface is in contact with the ball 310. Since the ball 310 can roll freely, the original sliding friction is converted into rolling friction, which greatly reduces the friction resistance. At the same time, this design also reduces the heat and wear generated by friction during the operation of the cross coupling 2, thereby increasing the service life of the coupling.

[0040] See also Figure 1 , Figure 2 and Figure 3Two second buffer springs 311 are fixedly connected to the other side of the top of the first base plate 301, and the top ends of the two second buffer springs 311 are fixedly connected to the first lower support platform 312, and the inner wall of the first lower support platform 312 is engaged with the ball 310. By arranging two second buffer springs 311 and the first lower support platform 312 on the other side of the top of the first base plate 301, additional support points are provided for the cross coupling 2, so that during the operation of the cross coupling 2, not only the upper cross coupling 2 is stably supported, but the lower cross coupling 2 also has corresponding buffering and supporting structures, thereby ensuring the overall stability of the coupling mechanism. At the same time, the inner wall of the first lower support platform 312 is engaged with the ball 310, and when the cross coupling 2 rotates, the ball 310 can roll freely between the first lower support platform 312 and the upper support platform 304, reducing friction and wear and improving support efficiency.

[0041] See also Figure 1 , Figure 2 and Figure 3 A plurality of rolling balls 310 are provided, and the plurality of rolling balls 310 are arranged equidistantly in a ring shape. By providing a plurality of rolling balls 310 and arranging them equidistantly in a ring shape, it is ensured that the support for the cross coupling 2 is all-round and uniform, and stress concentration and imbalance that may be caused by single-point support are avoided, thereby improving the stability and reliability of the support. At the same time, the presence of a plurality of rolling balls 310 further disperses the friction and wear, so that the load borne by each rolling ball 310 is more uniform, extending their service life, and improving the operating efficiency and durability of the entire drive mechanism.

[0042] The implementation principle of the utility model is as follows: first, the adjusting ring 306 is rotated to adjust the supporting force of the first buffer spring 308 on the first upper support platform 304, so that the upper support platform 304 can maintain a stable support for the cross coupling 2 above, and at the same time, the first lower support platform 312 provides support for the cross coupling 2 below, so that no matter what position the cross coupling 2 is in during operation, it can be stably supported;

[0043] The rolling balls 310 reduce the friction force and prevent the outer surface of the cross coupling 2 from being greatly worn.

[0044] Embodiment 2:

[0045] See also Figure 4A second supporting mechanism 4 is arranged below the cross coupling 2, and the second supporting mechanism 4 includes a second bottom plate 401. The existence of the second supporting mechanism 4 provides another supporting method for the cross coupling 2, thereby effectively adapting to the angle of the coupling during the tilting operation and enhancing the supporting stability of the cross coupling 2. At the same time, the second bottom plate 401 in the second supporting mechanism 4 serves as the base of the entire supporting mechanism, providing a stable installation platform for other supporting components, which not only ensures the structural strength of the second supporting mechanism 4 itself, but also helps to maintain the compactness and integrity of the entire driving mechanism.

[0046] See also Figure 4 The second bottom plate 401 is fixedly connected with a third buffer spring group 402 on both sides, and the top of the third buffer spring group 402 is fixedly connected with a second lower support platform 403. By fixing the third buffer spring group 402 on both sides of the second bottom plate 401, a support with a buffering function is provided for the cross coupling 2, so that when the cross coupling 2 below is subjected to external impact or vibration, the third buffer spring group 402 can absorb and disperse these forces, thereby reducing direct damage to the coupling. At the same time, the second lower support platform 403 provides a supporting surface matching the lower surface of the cross coupling 2, so that the coupling can obtain uniform supporting force during operation, thereby ensuring the stability and accuracy of the support.

[0047] See also Figure 4 A second support rod 404 is arranged between the two third buffer spring groups 402, and a second inner rod 405 is slidably connected to the top end of the second support rod 404. The second inner rod 405 slidably connected to the top end of the second support rod 404 provides flexibility for the supporting structure, allowing the second inner rod 405 to slide up and down to a certain extent inside the second support rod 404 to adapt to the vertical displacement that may occur in the cross coupling 2 during operation. The existence of the second inner rod 405 not only ensures the continuity of the support, but also cooperates with the subsequent springs to buffer the vibration caused by the displacement of the coupling, thereby improving the durability of the entire driving mechanism.

[0048] See also Figure 4 There are two second support rods 404 and two second inner rods 405, and a balance plate 406 is rotatably connected between the two second inner rods 405. The balance plate 406 can rotate freely between the two second inner rods 405, so that it can be adjusted according to the real-time position and angle of the cross coupling 2, so as to always maintain stable support for the coupling. At the same time, no matter how the position and posture of the cross coupling 2 changes during operation, the balance plate 406 can redistribute the supporting force by rotating, ensuring that the supporting point always matches the center of gravity of the coupling, thereby improving the stability and reliability of the support, and effectively reducing the vibration and noise caused by improper support, thereby improving the working performance and life of the entire drive mechanism.

[0049] See also Figure 4 The second upper support platforms 407 are rotatably connected to both sides of the balance plate 406, and the interiors of the two second upper support platforms 407 are engaged with the rolling balls 310. By rotatably connecting the second upper support platforms 407 on both sides of the balance plate 406 and ensuring that the interiors of the two second upper support platforms 407 are engaged with the rolling balls 310, a more precise and stable support is provided for the cross coupling 2. At the same time, the free rolling characteristics of the rolling balls 310 convert the friction between the support points into rolling friction, which greatly reduces the friction resistance and improves the support efficiency.

[0050] See also Figure 4 The top end of the second support rod 404 is threadedly connected to the adjustment ring 306, and a fourth buffer spring 408 is arranged inside the groove 307. By threading the top end of the second support rod 404 to the adjustment ring 306, the fine-tuning function of the support elasticity is achieved, so that the staff can accurately adjust the support force by rotating the adjustment ring 306 as needed, which effectively improves the adaptability of the support. At the same time, the fourth buffer spring 408 can provide additional buffering effect when the cross coupling 2 is impacted or vibrated, absorb and disperse these forces, thereby protecting the coupling and the entire drive mechanism from damage.

[0051] The implementation principle of the utility model is: first, through the balance plate 406, the second upper support platforms 407 on both sides of the balance plate 406 can reliably support the two ends of the upper cross coupling 2 according to the angle of the cross coupling 2, and at the same time, the two second lower support platforms 403 can provide reliable support for the two ends of the lower cross coupling 2, no matter what angle it is at.

[0052] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0053] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
