Abstract
Description
Technical Field
[0001] This application relates to the field of hot rolling equipment technology, specifically a cobalt-based alloy hot rolling equipment. Background Technology
[0002] Hot rolling mills are equipment for pressure processing of cobalt-based alloys. By applying pressure to cobalt-based alloy billets, they cause plastic deformation at high temperatures, thereby realizing the rolling processing of materials. The billets can be rolled into products of various specifications such as plates, strips, and profiles, providing basic raw materials for subsequent industrial production.
[0003] In the hot rolling production of cobalt-based alloys, most equipment adopts a manual cleaning mode of periodic shutdown for the cleaning of rolls. Workers need to wear high-temperature resistant protective equipment and use tools such as wire brushes and hard scrapers to clean the surface of the rolls in a relatively static state.
[0004] However, manual cleaning of the rolls results in inconsistent cleaning effectiveness. Different personnel have varying cleaning intensity and scope at different times, making it difficult to ensure that the roll surface is cleaned evenly. Consequently, residual oxide scale, metal debris, and other impurities on the rolls will reduce the quality of subsequent metal rolling. Furthermore, manual cleaning is inefficient, as each roll cleaning requires stopping the machine, which interrupts the production process and reduces overall production efficiency. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a hot rolling equipment for cobalt-based alloys.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cobalt-based alloy hot rolling equipment, including a frame, two sets of first transmission seats that can be horizontally lifted and lowered are installed on the upper part of the frame, and first rolls are rotated on the two sets of first transmission seats; two sets of second transmission seats are installed on the lower part of the frame, and second rolls are rotated on the two sets of second transmission seats.
[0007] A cleaning assembly is mounted on the frame. The cleaning assembly includes a first bracket mounted on the first transmission seat and a second bracket mounted on the second transmission seat. Both the first bracket and the second bracket are equipped with guide plates. A first cleaning roller, which is driven by a power and rotates, is mounted on the upper guide plate and is adapted to the first roller. A second cleaning roller, which is driven by a power and rotates, is mounted on the lower guide plate and is adapted to the second roller.
[0008] A drive assembly, mounted on the frame, is adapted to power the cleaning assembly.
[0009] Furthermore, the guide plate has a guide hole, and the first bracket and the second bracket are both equipped with a collection box located below the guide plate. The position of the guide hole corresponds to the position of the collection box.
[0010] Furthermore, one end of the first cleaning roller is equipped with an adapter shaft, one end of the adapter shaft 34 is equipped with a first bevel gear, and one end of the second cleaning roller passes through the machine frame and is equipped with a second bevel gear.
[0011] Furthermore, an adapter sleeve is installed on the adapter shaft, and two sets of symmetrically distributed limiting blocks are installed on the adapter sleeve. An movable hole is opened on the upper part of one side of the frame, and limiting grooves adapted to the limiting blocks are opened on both sides of the movable hole.
[0012] Furthermore, the drive assembly includes a long rod that is driven by power and rotates on one side of the frame, and a third bevel gear that meshes with the second bevel gear is mounted on the long rod;
[0013] A transmission sleeve is installed on one side of the first bracket, and an intermediate cylinder is rotatably installed inside the transmission sleeve. A fourth bevel gear that meshes with the first bevel gear is installed at one end of the intermediate cylinder.
[0014] Furthermore, a motor is installed on the lower part of one side of the frame, and the output end of the motor is connected to one end of the long rod.
[0015] Furthermore, one end of the long rod is equipped with multiple limiting strips, and the middle cylinder has a sliding groove adapted to the limiting strips.
[0016] By adopting the above technical solution, this utility model has the following beneficial effects: the cleaning component, by installing the first bracket with the first transmission seat and the second bracket with the second transmission seat, enables the first cleaning roller and the second cleaning roller to always maintain a proper fit with the first and second rolls. With the stable power provided by the drive component, real-time and efficient cleaning of the surface of the two rolls can be achieved, reducing the impact of impurities on rolling quality. At the same time, cleaning can be completed without stopping the machine, ensuring production continuity and improving production efficiency. Attached Figure Description

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a cobalt-based alloy hot rolling equipment, including a support 1. The support 1 serves as the basic support component of the entire equipment. Its structure can effectively distribute the weight of each component of the equipment and the impact force generated during the rolling process, preventing the equipment from shifting or deforming during long-term operation. A transmission box 11 is bolted to one end of the support 1. The transmission box 11 is a prior art device, which integrates gear sets, bearings and other components for power transmission and speed regulation. It can convert the power of the external power source into the power adapted to the rotation of the rolls according to the rolling process requirements, ensuring that the rolls can perform rolling operations at a stable speed.
[0027] Couplings 12 are hinged to the output shaft of the transmission box 11, and a transmission shaft 13 is hinged to one end of each coupling 12. The coupling 12, as a component connecting the transmission box 11 and the transmission shaft 13, can effectively compensate for the installation error between the output shaft of the transmission box 11 and the transmission shaft 13, and absorb the vibration and impact generated during the rolling process, reduce the damage to the transmission components caused by vibration, and ensure the smoothness of power transmission. Meanwhile, the length and installation position of the transmission shaft 13 are adapted to the overall layout of the equipment and the installation position of the rolls. Its main function is to transmit the power output from the transmission box 11 to the rolls, provide power support for the rotation of the rolls, and ensure that the rolls can rotate stably at the set speed to meet the rolling requirements of cobalt-based alloy billets.
[0028] A frame 2 is bolted to the other end of the support 1. The frame 2 has sufficient strength and rigidity to support the installation and operation of the remaining components, and provides a mounting base for the cleaning and driving parts. Mounting seats 21 are bolted to both sides of the upper part of the frame 2. Hydraulic push rods 22 are bolted to the mounting seats 21. The position of the mounting seats 21 must be adapted to the installation requirements of the hydraulic push rods 22. Its main function is to provide a stable mounting carrier for the hydraulic push rods 22, ensuring that the hydraulic push rods 22 can maintain a fixed installation position during operation, and preventing the decrease in the action accuracy of the hydraulic push rods 22 due to unstable installation.
[0029] Meanwhile, the hydraulic push rod 22, as the actuator for adjusting the position of the rolls, can move the transmission seat up and down through its own telescopic movement according to the requirements of the rolling process for the thickness of the billet, thereby adjusting the distance between the two sets of rolls and controlling the rolling thickness of the cobalt-based alloy billet. The output end of the hydraulic push rod 22 is bolted to the first transmission seat 23, and the first rolls 25 are rotatably connected to the two sets of first transmission seats 23. The first transmission seat 23 is equipped with bearings to support the rotation of the first rolls 25, which can ensure that the first rolls 25 maintain stable coaxiality during rotation and prevent uneven thickness or shape deviation of the rolled billet due to the offset of the first rolls 25.
[0030] One end of the upper drive shaft 13 passes through the first drive seat 23 and is connected to one end of the first roll 25. This connection method must ensure smooth power transmission between the drive shaft 13 and the first roll 25, prevent power transmission interruption or slippage, and ensure that the first roll 25 can rotate stably under the drive of the drive shaft 13.
[0031] Second transmission seats 24 are bolted to both sides of the lower part of the frame 2. Second rolls 26 are rotatably connected to the two sets of second transmission seats 24. The structure of the second transmission seats 24 is similar to that of the first transmission seats 23. They also have bearings installed inside to support the rotation of the second rolls 26. The second rolls 26 work together with the first rolls 25 to complete the rolling of the cobalt-based alloy billet. Their surface treatment process is the same as that of the first rolls 25 to ensure that they can withstand the extrusion and friction of the cobalt-based alloy billet during the rolling process and maintain stable rolling performance over a long period of time.
[0032] One end of the lower drive shaft 13 passes through the second drive seat 24 and is connected to one end of the second roll 26. This connection structure must be consistent with the connection structure between the upper drive shaft 13 and the first roll 25 to ensure that the power can be evenly transmitted to the second roll 26, so that the second roll 26 and the first roll 25 can rotate synchronously, and avoid the billet from being stretched or wrinkled due to the asynchronous speed of the two rolls.
[0033] like Figures 2-5 As shown, a cleaning component 3 is installed on the frame 2. This cleaning component 3 performs real-time cleaning of the surfaces of the first roll 25 and the second roll 26 during the rolling process, removing impurities such as oxide scale and metal shavings attached to the roll surfaces to prevent impurities from affecting the quality of subsequent rolled products. The cleaning component 3 includes a first bracket 31 bolted to the first transmission seat 23. The installation position of the first bracket 31 is adapted to the position of the first roll 25. A second bracket 311 is installed on the second transmission seat 24. The second bracket 311 has the same structure as the first bracket 31 and is installed in a position adapted to the second roll 26, ensuring that the cleaning component 3 can perform cleaning operations on both the upper and lower rolls simultaneously.
[0034] Guide plates 32 are bolted to both the first bracket 31 and the second bracket 311. Guide holes 321 are opened at one end of the bottom of the guide plates 32. The installation angle of the guide plates 32 ensures that they can smoothly receive the impurities removed from the surface of the roll by the cleaning roller, and guide the impurities to the guide holes 321 through their own inclined structure, preventing the impurities from accumulating on the surface of the guide plates 32. At the same time, the surface of the guide plates 32 is kept smooth to reduce the resistance of the impurities during the sliding process, ensuring that the impurities can slide down quickly and smoothly.
[0035] A collection box 322 located below the guide plate 32 is bolted to both the first bracket 31 and the second bracket 311. The opening position of the guide hole 321 corresponds to the position of the collection box 322, ensuring that impurities can smoothly enter the collection box 322 through the guide hole 321. The collection box 322 serves as a container for collecting impurities, and its volume is sufficient to hold the impurities generated within a certain period of time, reducing the frequency of cleaning impurities by staff. At the same time, the connection between the collection box 322 and the bracket must be easy to disassemble, so that staff can clean the collected impurities regularly and prevent excessive accumulation of impurities from affecting the normal operation of the cleaning component 3.
[0036] The other end of the upper guide plate 32 is rotatably connected to a first cleaning roller 33. The length of the first cleaning roller 33 must be matched with the length of the first roll 25 to ensure that it can fully cover the surface of the first roll 25 and reduce the occurrence of cleaning dead corners. At the same time, the contact pressure between the first cleaning roller 33 and the first roll 25 needs to be adjusted to ensure that impurities on the surface of the roll can be effectively removed, while reducing the wear of the roll surface or damage to the cleaning roller caused by excessive contact pressure.
[0037] A second cleaning roller 331 is rotatably connected to the other end of the lower guide plate 32. The structure of the second cleaning roller 331 is the same as that of the first cleaning roller 33, and it is adapted to the second roll 26. Through contact friction with the second roll 26, it removes impurities from the surface of the second roll 26, ensuring that the upper and lower rolls remain clean during the rolling process. The first cleaning roller 33 is adapted to the first roll 25, and the second cleaning roller 331 is adapted to the second roll 26. The adaptation relationship is mainly reflected in the fact that the diameter and length of the cleaning roller match the diameter and length of the roll, and the rotation direction of the cleaning roller matches the rotation direction of the roll. Through the friction generated by the rotation, the efficiency of impurity removal is improved.
[0038] An adapter shaft 34 is bolted to one end of the first cleaning roller 33. The function of the adapter shaft 34 is to connect the first cleaning roller 33 to the bevel gear part, and to transmit the power transmitted by the drive part to the first cleaning roller 33, so as to provide power for the rotation of the first cleaning roller 33. The adapter shaft 34 is installed with the first cleaning roller 33 to maintain coaxiality, so as to prevent the first cleaning roller 33 from shaking when rotating due to coaxiality deviation, which would affect the cleaning effect or damage the parts.
[0039] An adapter sleeve 341 is fixedly installed on the adapter shaft 34. Two sets of symmetrically distributed limiting blocks 342 are fixedly installed on the adapter sleeve 341. The function of the limiting blocks 342 is to restrict the movement direction of the adapter shaft 34, ensuring that the first cleaning roller 33 can only move up and down synchronously with the first roller 25, preventing the first cleaning roller 33 from shifting left or right or rotating, and ensuring that the first cleaning roller 33 and the first roller 25 always maintain a good contact state.
[0040] A movable hole 343 is provided on one side of the upper part of the frame 2. The shape and size of the movable hole 343 are adapted to the diameter and movement range of the adapter shaft 34, providing sufficient space for the vertical movement of the adapter shaft 34. On both sides of the movable hole 343, a limiting groove 344 adapted to the limiting block 342 is provided. The length of the limiting groove 344 is designed according to the adjustment range of the first roller 25, ensuring that the limiting block 342 can slide smoothly in the limiting groove 344 during the vertical adjustment of the first roller 25. At the same time, the side wall of the limiting groove 344 restricts the left and right movement of the limiting block 342, thereby restricting the left and right movement of the adapter shaft 34 and ensuring the stability of the position of the first cleaning roller 33.
[0041] One end of the adapter shaft 34 extends out of the movable hole 343 and is coaxially mounted with a first bevel gear 35. As a power transmission component, the number of teeth and module of the first bevel gear 35 must be matched with the gear of the drive part to ensure smooth meshing and efficient power transmission. The coaxial installation of the first bevel gear 35 and the adapter shaft 34 must be precise to prevent poor gear meshing due to installation deviation, resulting in noise, vibration, or excessive gear wear. One end of the second cleaning roller 331 passes through the frame 2 and is coaxially mounted with a second bevel gear 351. The structure of the second bevel gear 351 is the same as that of the first bevel gear 35. Its number of teeth and module are matched with the gear of the drive part, transmitting the power of the drive part to the second cleaning roller 331, driving the second cleaning roller 331 to rotate, and realizing the cleaning operation of the second roller 26.
[0042] like Figures 3-6 As shown, a drive assembly 4 is installed on one side of the frame 2. The drive assembly 4 serves as the power source for the cleaning assembly 3. Its function is to provide stable power for the rotation of the first cleaning roller 33 and the second cleaning roller 331, ensuring that the cleaning assembly 3 can perform cleaning operations continuously and efficiently.
[0043] The drive assembly 4 includes a motor 41 bolted to the lower part of the outer wall of one side of the frame 2. After the motor 41 is powered on, it is started by the corresponding controller and can provide sufficient power to drive the cleaning roller to rotate. It also has stable speed adjustment performance and can adjust the speed of the cleaning roller according to the speed of the roller and the degree of impurity adhesion to optimize the cleaning effect. A long rod 42 is coaxially mounted on the output end of the motor 41. A third bevel gear 43 that meshes with the second bevel gear 351 is mounted on the long rod 42. The installation of the third bevel gear 43 and the long rod 42 must be firm to ensure that the long rod 42 can drive the third bevel gear 43 to rotate synchronously when it rotates. Then, through the meshing with the second bevel gear 351, the power is transmitted to the second cleaning roller 331.
[0044] The number of teeth and module of the third bevel gear 43 are matched with those of the second bevel gear 351 to ensure that the transmission ratio when the two meshes meets the design requirements, so that the second cleaning roller 331 can obtain a suitable rotation speed and ensure the cleaning effect.
[0045] A transmission sleeve 44 is bolted to the outer wall of one side of the first support 31. An intermediate cylinder 45 is rotatably connected inside the transmission sleeve 44. A fourth bevel gear 46 is coaxially mounted at one end of the intermediate cylinder 45, meshing with the first bevel gear 35. The number of teeth and the module of the fourth bevel gear 46 are matched with those of the first bevel gear 35. Through meshing with the first bevel gear 35, the power transmitted by the intermediate cylinder 45 is converted into the rotational power of the first cleaning roller 33, driving the first cleaning roller 33 to rotate.
[0046] Multiple limiting strips 47 are fixedly installed at one end of the long rod 42. A sliding groove 48 adapted to the limiting strips 47 is opened in the intermediate cylinder 45. The number, shape and distribution of the limiting strips 47 are adapted to the sliding groove 48 in the intermediate cylinder 45 to ensure that the limiting strips 47 can be completely embedded in the sliding groove 48. Through the cooperation of the limiting strips 47 and the sliding groove 48, the power transmission between the long rod 42 and the intermediate cylinder 45 is realized. At the same time, the intermediate cylinder 45 is allowed to slide within a certain range in the axial direction of the long rod 42 to adapt to the position change of the first cleaning roller 33 when it moves up and down with the first roller 25. The length of the sliding groove 48 is designed according to the maximum range of movement of the first cleaning roller 33 to ensure that the intermediate cylinder 45 can slide smoothly on the long rod 42 through the cooperation of the sliding groove 48 and the limiting strips 47 when the first cleaning roller 33 moves up and down.
