Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a rolling mill roll that is easy to change quickly. Background Technology

[0002] A rolling mill roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing and transmits the rolling force to the mill stand through the bearing housing and the pressing device. The drive end shaft end is connected to a gear housing via a connecting shaft, transmitting the rotational torque of the motor to the roll.

[0003] In the rolling production process of steel, non-ferrous metals, etc., the roll is one of the core components. Its performance directly affects the quality of rolled products and production efficiency. Traditional roll replacement methods are usually cumbersome and require a lot of time and manpower for disassembly and installation. Utility Model Content

[0004] The purpose of this invention is to provide a roll that is easy to change quickly, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a roll that is easy to change quickly, including a roll body, a quick locking mechanism is provided on both the left and right sides of the roll body, and an adjustment mechanism is provided on the right side of the quick locking mechanism;

[0006] The quick-locking mechanism includes a mounting plate, a support plate fixedly connected to the bottom left side of the mounting plate, a connecting sleeve rotatably connected to the support plate, a motor fixedly connected to the left side of the connecting sleeve, a plurality of grooves opened at one end of the connecting sleeve, a connecting block provided in each of the plurality of grooves, a first spring fixedly connected to the top of the connecting block, a fixed ball fixedly connected to the inner side of the connecting block, a support ring fixedly connected to the outer side of the connecting sleeve, a second spring fixedly connected to one side of the support ring, a compression sleeve provided on the outer side of the support ring, a compression block fixedly connected to the inner wall of the compression sleeve, and a fixing block fixedly connected to the inner wall of the connecting sleeve.

[0007] Preferably, the motor is fixedly connected to the left side of the support plate, and the end of the first spring away from the connecting block is fixedly connected to the top wall of the groove.

[0008] Furthermore, the motor is fixedly connected to the left side of the support plate. The connection method of the first spring is also explained. The end of the first spring away from the connecting block is fixedly connected to the inner top wall of the groove. This design ensures that the motor has a stable installation position on the support plate and that the first spring can play its elastic role normally in the groove, providing a stable mechanical basis for the operation of the connecting block and other components in the quick locking mechanism.

[0009] Preferably, there are multiple fixed balls, which are movably connected to multiple grooves opened at one end of the connecting sleeve, and the end of the second spring away from the support ring is fixedly connected to the inner side of the extrusion block.

[0010] Furthermore, multiple fixed balls are provided, and these fixed balls are movably connected to multiple grooves opened at one end of the connecting sleeve. This layout allows the fixed balls to rotate flexibly within the grooves, facilitating their cooperation with the roll body to achieve the locking function. The connection method of the second spring is also explained. The end of the second spring away from the support ring is fixedly connected to the inner side of the extrusion block, ensuring that the second spring can extend and retract normally between the extrusion sleeve and the support ring, providing elastic force for the extrusion sleeve to extrude the components on the connecting sleeve.

[0011] Preferably, the left and right sides of the roll body are provided with a plurality of grooves that are adapted to the bottom of the fixed balls, and the bottom of the plurality of fixed balls are movably connected to the grooves provided at one end of the roll body.

[0012] Furthermore, multiple grooves adapted to the bottom of the fixed balls are provided on the left and right sides of the roll body, and the bottom of the multiple fixed balls is movably connected to the groove provided at one end of the roll body. This design allows the fixed balls to be embedded in the grooves of the roll body. When the quick locking mechanism is working, the fixed balls cooperate with the grooves of the roll body to achieve quick locking and positioning of the roll body, ensuring the stability of the roll during operation.

[0013] Preferably, the adjusting mechanism includes a connecting plate, on which a screw is threadedly connected, a slider is provided on the left side of the screw, and a rotating rod is fixedly connected to the right side of the screw.

[0014] Preferably, the connecting plate is fixedly connected to the bottom right side of the mounting plate, and a sliding groove is provided on the bottom right side of the mounting plate, and the top of the slider is slidably connected to the sliding groove provided on the bottom right side of the mounting plate.

[0015] Furthermore, the connecting plate is fixedly connected to the bottom right side of the mounting plate. A groove is provided on the bottom right side of the mounting plate, and the top of the slider is slidably connected to the groove on the bottom right side of the mounting plate. This design ensures that the slider can slide stably in the groove at the bottom of the mounting plate, so that the rotation of the screw in the adjustment mechanism can be smoothly converted into the linear motion of the slider, thereby realizing the adjustment function.

[0016] Preferably, there are two connecting sleeves, which are rotatably connected to the support plate and the slider, respectively, and the left and right ends of the roller body are respectively inserted into the two connecting sleeves.

[0017] Furthermore, there are two connecting sleeves, and the two connecting sleeves are rotatably connected to the support plate and the slider respectively. This design allows the connecting sleeves to rotate flexibly on the support plate and the slider, which facilitates the installation and disassembly of the roll body. At the same time, the left and right ends of the roll body are respectively inserted into the two connecting sleeves. The insertion method realizes the quick connection between the roll body and the quick locking mechanism, which facilitates the quick replacement of the roll.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] First, in this invention, one end of the roll body is carefully aligned with the connecting sleeve in the quick-locking mechanism equipped with a motor. Since multiple grooves are opened at one end of the connecting sleeve, and a connecting block, a first spring, and a fixed ball are arranged in the grooves, during the docking process, the end of the roll body will gradually squeeze the fixed ball. After being squeezed, the fixed ball will overcome the elastic force of the first spring and retract into the groove, thereby making room for the end of the roll body to insert, so that the roll body can be smoothly inserted into the connecting sleeve. When the end of the roll body is inserted to a suitable depth, that is, when the groove on the surface of the roll body that is adapted to the bottom of the fixed ball is aligned with the bottom of the fixed ball, the first spring returns to its deformation, pushing the connecting block and the fixed ball to move outward, so that the bottom of the fixed ball is locked into the groove on the surface of the roll body, thus initially fixing the end of the roll body with the motor. Observe the relative position of the other end of the roll body and the connecting sleeve in another quick-locking mechanism. According to the actual length of the roll body, adjust the position of the connecting sleeve using the adjustment mechanism. After adjusting the position of the other end of the connecting sleeve, insert the other end of the roll body into the connecting sleeve. The insertion process is similar to that of the end with the motor installed. The end of the roll body presses against the fixed ball inside the connecting sleeve, causing the fixed ball to contract against the elastic force of the first spring. When the groove on the surface of the roll body aligns with the bottom of the fixed ball, the first spring pushes the fixed ball into the groove, completing the initial fixation of the other end of the roll body. After the roll is installed and locked, check whether the connections of each component are secure. After confirming that everything is correct, start the motor. The motor drives the connecting sleeve... The connecting sleeve drives the roll body to rotate, starting the rolling process. When the roll needs to be replaced, the motor is stopped first, and then the locking control device is operated to reset the extrusion sleeve, releasing the extrusion block's pressure on the fixed balls. Next, the roll body is pulled to both sides, and the end of the roll body squeezes the fixed balls, causing the fixed balls to contract against the first spring force, thereby pulling the roll body out of the two connecting sleeves and completing the roll disassembly. Through the coordinated work of the quick locking mechanism and the adjusting mechanism, the roll replacement time can be greatly shortened, production efficiency can be significantly improved, and production downtime caused by roll replacement can be reduced.

[0020] Secondly, in the rotating adjustment mechanism of this utility model, the rotating rod drives the screw to rotate. Because the screw is threadedly connected to the connecting plate, and the top of the slider is slidably connected to the groove opened on the bottom right side of the mounting plate, the rotation of the screw will push the slider to move in the groove. Since another connecting sleeve is rotatably connected to the slider, the movement of the slider will drive this connecting sleeve to move synchronously, so that it gradually approaches the other end of the roll body until the connecting sleeve and the other end of the roll body can be smoothly connected, so that the roll device can adapt to the installation requirements of rolls of different lengths.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A roll that is easy to change quickly includes a roll body 1, quick locking mechanisms 2 are provided on both the left and right sides of the roll body 1, and an adjustment mechanism 3 is provided on the right side of the quick locking mechanism 2.

[0030] The quick-locking mechanism 2 includes a mounting plate 21. A support plate 22 is fixedly connected to the bottom left side of the mounting plate 21. A connecting sleeve 23 is rotatably connected to the support plate 22. A motor 24 is fixedly connected to the left side of the connecting sleeve 23. Multiple grooves are provided at one end of the connecting sleeve 23. A connecting block 25 is provided in each of the multiple grooves. A first spring 26 is fixedly connected to the top of the connecting block 25. A fixing ball 27 is fixedly connected to the inner side of the connecting block 25. A support ring 28 is fixedly connected to the outer side of the connecting sleeve 23. A second spring 29 is fixedly connected to one side of the support ring 28. A compression sleeve 210 is provided on the outer side of the support ring 28. A compression block 211 is fixedly connected to the inner wall of the compression sleeve 210. A fixing block 212 is fixedly connected to the inner wall of the connecting sleeve 23.

[0031] Specifically, the motor 24 is fixedly connected to the left side of the support plate 22, and the end of the first spring 26 away from the connecting block 25 is fixedly connected to the top wall of the groove.

[0032] Specifically, multiple fixed balls 27 are provided, and the multiple fixed balls 27 are movably connected in multiple grooves opened at one end of the connecting sleeve 23. The end of the second spring 29 away from the support ring 28 is fixedly connected to the inner side of the extrusion block 211.

[0033] Specifically, multiple fixed balls 27 are provided on the left and right sides of the roll body 1 with grooves that are adapted to the bottom of the balls 27, and the bottom of the balls 27 are movably connected to the grooves provided at one end of the roll body 1.

[0034] Through the above technical solution, firstly, one end of the roll body 1 is carefully aligned with the connecting sleeve 23 in the quick-locking mechanism 2 equipped with the motor 24. Since one end of the connecting sleeve 23 has multiple grooves, and the grooves are equipped with connecting blocks 25, first springs 26, and fixing balls 27, during the docking process, the end of the roll body 1 will gradually squeeze the fixing balls 27. After being squeezed, the fixing balls 27 will overcome the elastic force of the first spring 26 and retract into the groove, thereby making room for the end of the roll body 1 to insert, so that the roll body... 1. It can be smoothly inserted into the connecting sleeve 23. When the end of the roll body 1 is inserted to a suitable depth, that is, when the groove on the surface of the roll body 1 that is adapted to the bottom of the fixed ball 27 is aligned with the bottom of the fixed ball 27, the first spring 26 restores its deformation, pushes the connecting block 25 and the fixed ball 27 to move outward, so that the bottom of the fixed ball 27 is stuck in the groove on the surface of the roll body 1, and initially realizes the fixation of the end of the roll body 1 with the motor 24. Observe the relative position of the other end of the roll body 1 and the connecting sleeve 23 in another quick locking mechanism 2. Based on the actual length of the roll body 1, the position of the connecting sleeve 23 is adjusted by operating the adjustment mechanism 3. After adjusting the position of the other end of the connecting sleeve 23, the other end of the roll body 1 is inserted into the connecting sleeve 23. The insertion process is similar to that of the end with the motor 24 installed. The end of the roll body 1 presses against the fixed ball 27 inside the connecting sleeve 23, causing the fixed ball 27 to contract against the elastic force of the first spring 26. When the groove on the surface of the roll body 1 is aligned with the bottom of the fixed ball 27, the first spring 26 pushes the fixed ball 27 into the groove, completing the initial fixation of the other end of the roll body 1. After the roll is installed and locked, the connection of each component is checked to ensure it is secure. After confirming that there are no errors, the internal wiring connection of the motor 24 is existing technology and will not be described in detail. The motor 24 is started, and the motor 24 drives the roll body 1 to rotate through the connecting sleeve 23 to start the rolling operation. When the roll needs to be replaced, the motor 24 is stopped first, and then the locking control device is operated to reset the extrusion sleeve 210 and release the extrusion block 211 from the fixed ball 27. Then, the roll body 1 is pulled to both sides, and the end of the roll body 1 extrudes the fixed ball 27, causing the fixed ball 27 to contract against the elastic force of the first spring 26, thereby pulling the roll body 1 out from the two connecting sleeves 23 and completing the disassembly of the roll. Through the coordinated work of the quick locking mechanism 2 and the adjusting mechanism 3, the roll replacement time can be greatly shortened, the production efficiency can be significantly improved, and the production downtime caused by the roll replacement can be reduced.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4Furthermore, based on Embodiment 1, the adjustment mechanism 3 includes a connecting plate 31, a screw 32 is threadedly connected to the connecting plate 31, a slider 33 is provided on the left side of the screw 32, and a rotating rod 34 is fixedly connected to the right side of the screw 32.

[0037] Specifically, the connecting plate 31 is fixedly connected to the bottom right side of the mounting plate 21, and a groove is provided on the bottom right side of the mounting plate 21. The top of the slider 33 is slidably connected to the groove provided on the bottom right side of the mounting plate 21.

[0038] Specifically, there are two connecting sleeves 23. The two connecting sleeves 23 are rotatably connected to the support plate 22 and the slider 33 respectively. The left and right ends of the roll body 1 are respectively inserted into the two connecting sleeves 23.

[0039] Through the above technical solution, the rotating rod 34 in the rotating adjustment mechanism 3 drives the screw 32 to rotate. Because the screw 32 is threadedly connected to the connecting plate 31, and the top of the slider 33 is slidably connected to the groove opened on the bottom right side of the mounting plate 21, the rotation of the screw 32 will push the slider 33 to move in the groove. Since another connecting sleeve 23 is rotatably connected to the slider 33, the movement of the slider 33 will drive the connecting sleeve 23 to move synchronously, so that it gradually approaches the other end of the roll body 1 until the connecting sleeve 23 and the other end of the roll body 1 can be smoothly connected, so that the roll device can adapt to the installation requirements of rolls of different lengths.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
