Description

Technical Field

[0001] This utility model relates to the field of anode carbon block casting, and in particular to a spring-type carbon block damping system for casting stations. Background Technology

[0002] When producing anode carbon blocks in an electrolytic aluminum production workshop, the anode aluminum guide rod and the carbon block need to be cast together with molten iron. Currently, the production of anode aluminum guide rods and carbon blocks is usually carried out using an automated casting station. During casting, a conveying mechanism is used to move the carbon block to the casting station, and then the casting ladle is flipped to achieve the casting connection between the aluminum guide rod and the anode carbon block.

[0003] Currently, a Chinese patent application with publication number CN 219169604 U and publication date of June 13, 2023, proposes an automatic casting production line for aluminum electrolysis anode carbon blocks and steel claws. The production line includes a carbon block assembly, a molten iron ladle conveying mechanism, and an automatic casting mechanism. The carbon block assembly consists of a carbon block and steel claws. Several blind holes are formed on the upper surface of the carbon block, and the lower ends of the steel claws are inserted into the corresponding blind holes. A gap is left between the steel claws and the blind holes for casting molten iron. The molten iron ladle conveying mechanism is used to convey the molten iron ladle to the casting station. The automatic casting mechanism is used to pour the molten iron into the blind holes on the carbon block.

[0004] In use, molten iron is conveyed to the automatic casting mechanism via the molten iron ladle conveying mechanism. Then, the automatic casting mechanism is used to cast the molten iron into the blind holes on the carbon block, completing the casting connection between the anode guide rod and the carbon block.

[0005] Regarding the aforementioned technologies, when casting carbon blocks, it is necessary to move the carbon blocks to the corresponding casting station. During the movement of the carbon blocks, a damping system needs to be set up to stop the carbon blocks at the casting station. The damping system achieves this by setting up a damping plate that rubs against the carbon blocks. However, due to the wear of the damping plate after prolonged friction, the coefficient of friction changes, often resulting in the carbon block slider or the carbon blocks not reaching the correct position. This requires secondary adjustment of the carbon block's position, leading to low production efficiency. Utility Model Content

[0006] In order to enable carbon blocks to stop more precisely at the casting station, reduce human intervention, and thus improve production efficiency, this utility model provides a spring-type carbon block damping system for casting stations.

[0007] This utility model provides a spring-type carbon block damping system for a casting station, which adopts the following technical solution:

[0008] A spring-type carbon block damping system for a casting station includes: a damping plate assembly and a conveying assembly. The conveying assembly is used to drive the carbon block to move in a directional manner. The damping plate assembly includes a top plate, a bottom plate, a spring, and an adjusting bolt. The bottom plate is fixedly installed on the conveying assembly. The top plate is disposed above the bottom plate. The spring is disposed between the top plate and the bottom plate and has a tendency to move the top plate and the bottom plate away from each other. One end of the adjusting bolt is connected to the top plate, and the other end is connected to the bottom plate. A guide surface is provided above the top plate.

[0009] By adopting the above technical solution, the carbon block will move directionally along the conveying assembly. When the carbon block moves above the damping plate assembly, the top plate will contact the lower surface of the carbon block. The friction between the top plate and the lower surface of the carbon block will stop the carbon block above the top plate. After a long period of friction, the upper surface of the top plate will wear down, which will reduce the coefficient of friction and the height of the top plate, thus reducing the friction between the top plate and the carbon block. At this time, the adjusting bolt is loosened, and the top plate will move upward under the action of the spring, so that when the carbon block moves above the top plate, the top plate can continue to press against the bottom of the carbon block, increasing the friction between the top plate and the carbon block, so that the carbon block can stop more accurately at the casting position. At the same time, when the friction between the top plate and the bottom of the carbon block is too large, the adjusting bolt is tightened, so that the top plate moves downward relative to the bottom plate, thereby reducing the friction between the top plate and the bottom of the carbon block when the carbon block moves above the top plate.

[0010] In this way, by setting adjusting bolts and springs, the height of the top plate can be flexibly adjusted in cooperation with each other, thereby adjusting the friction between the damping plate and the bottom of the carbon block, so that the carbon block can stop more accurately at the casting station.

[0011] Optionally, spring limiting posts are provided at the bottom of the top plate and the top of the bottom plate, and the springs are sleeved on the spring slots.

[0012] By adopting the above technical solution, the spring limiting post forms a limiting structure, enabling the spring to maintain a vertical compression state; when the carbon block moves above the damping plate assembly, there will be lateral friction between the carbon block and the top plate, causing lateral displacement between the top plate and the bottom plate. The two ends of the spring are precisely constrained by the slots, which can reduce the lateral displacement or torsional deformation of the spring, enhance the structural stability of the damping system, and extend the service life of the spring.

[0013] Optionally, a guide rod is also provided below the top plate, the guide rod is arranged in a vertical direction, and a guide hole is provided on the bottom plate, the guide rod is slidably disposed in the guide hole.

[0014] By adopting the above technical solution, the guide rod and the guide hole form a precision sliding pair, restricting the top plate to move only in the vertical direction. When the carbon block is pressed on the top plate, during the relative movement between the carbon block and the top plate, the carbon block will apply a lateral force to the top plate. At this time, the guide rod slides in the vertical direction in the guide hole, reducing the possibility of lateral swaying of the top plate, effectively improving the guiding accuracy of the top plate movement, reducing the positioning deviation caused by the top plate's off-center load, and further improving the accuracy of the carbon block's stopping position.

[0015] Optionally, a wear-resistant layer is also provided above the top plate.

[0016] By adopting the above technical solution, during the frequent contact and friction between the carbon block and the top plate, the wear-resistant layer can effectively resist the wear of the top plate surface, maintain the accuracy of the friction coefficient and height of the top plate, significantly improve the durability and stability of the damping plate assembly, reduce the frequency of equipment maintenance, and reduce the impact of top plate friction on the movement accuracy of the carbon block.

[0017] Optionally, the conveying assembly includes a guide rail, a roller shaft, and a constant-speed motor. The roller shaft is rotatably mounted on the guide rail, and the constant-speed motor is fixedly mounted on the guide rail. The constant-speed motor is used to drive the roller shaft to rotate at a constant speed.

[0018] During the process of relative friction between the top plate and the carbon block driving the carbon block to stop, the frictional force is constant. The stopping position of the carbon block is also affected by its moving speed; a higher moving speed results in a longer sliding distance and smoother movement of the carbon block slider. Conversely, a low moving speed will cause the carbon block to fail to reach its designated position. By adopting the above technical solution, the constant-speed motor drives the roller shaft to maintain a constant rotational speed, ensuring consistent carbon block conveying speed. The continuous arrangement of the roller shaft along the guide rail creates a smooth conveying surface, allowing the carbon block to move more evenly and stably on the guide rail. Thus, by setting up a constant-speed conveying system, a stable moving speed is provided for the carbon block, reducing the impact of speed fluctuations on the carbon block's positioning accuracy and further improving the precision of the carbon block's stopping position.

[0019] Optionally, a torque limiter is also provided between the constant speed motor and the roller shaft, the torque limiter being used to engage or disengage the power transmission between the constant speed motor and the roller shaft.

[0020] During the movement of the carbon block on the guide rail, it is always supported by the roller. Even when the carbon block stops above the damping plate assembly, the roller continues to support the lower surface of the carbon block. However, if the roller continues to rotate when the carbon block stops, it will cause wear between the roller and the carbon block, affecting the service life of both. By adopting the above technical solution, when the carbon block stops above the damping plate, it stops moving. At this time, the roller generates rotational friction with the bottom of the carbon block, increasing the torque of the constant-speed motor driving the roller. At this point, the torque limiter interrupts the power transmission between the constant-speed motor and the roller, causing the roller to stop rotating under the friction of the carbon block. This reduces the wear between the roller and the carbon block, extends the service life of the device, and reduces the wear of the carbon block.

[0021] Optionally, a vertical plate is provided above the guide rail, and the vertical plate is arranged on both sides of the top plate along the length direction of the guide rail.

[0022] By adopting the above technical solution, the vertical plate can provide single-layer support on both sides of the top plate, reducing the probability of the top plate tilting under the pressure and friction of the carbon block, thereby improving the accuracy of the carbon block's stopping position.

[0023] Optionally, the outer circumferential surface of the roller is provided with a wear-resistant coating, which is used to increase the coefficient of friction of the roller surface.

[0024] By adopting the above technical solution, the wear-resistant coating layer not only enhances the wear resistance of the roller surface, but also increases the friction between the roller and the carbon block through the surface texture, thereby reducing the slippage phenomenon between the carbon block and the roller.

[0025] In summary, this utility model has at least one of the following beneficial technical effects:

[0026] By setting adjusting bolts and springs, the height of the top plate can be flexibly adjusted in cooperation with each other, thereby adjusting the friction between the damping plate and the bottom of the carbon block, so that the carbon block can stop more accurately at the casting station.

[0027] By setting a constant-speed motor to drive the roller shaft to rotate, the roller shaft can provide a stable moving speed for the carbon block when it moves on the roller shaft, reducing the impact of speed fluctuations on the positioning accuracy of the carbon block and further improving the accuracy of the carbon block's stopping position.

[0028] Equipped with a torque reducer, it can interrupt the power transmission between the constant speed motor and the roller shaft when the carbon block stops moving, causing the roller shaft to stop rotating under the friction of the carbon block, reducing the wear of the roller shaft and the carbon block, and extending the service life of the device.

Detailed Implementation

[0035] The following combination Figures 1 to 5 The present invention will be described in further detail below.

[0036] This utility model discloses a spring-type carbon block damping system for a casting station. (Refer to...) Figures 1 to 3 A spring-type carbon block damping system for a casting station mainly comprises a damping plate assembly 100 and a conveying assembly 200. When the casting station is in operation, carbon blocks are placed on the conveying assembly 200 and conveyed sequentially to the casting station. When the carbon block moves above the damping plate assembly 100, the bottom of the carbon block rubs against the damping plate, causing the carbon block to stop being conveyed forward and eventually stop at the casting station. The molten iron ladle at the casting station then pours the carbon block.

[0037] Reference Figure 1The conveying assembly 200 includes a guide rail 210, rollers 220, a constant-speed motor 230, and a torque limiter 240. The guide rail 210 is composed of parallel I-beams fixed to the ground. A vertical plate 211 is welded above the guide rail 210 for mounting the rollers 220. Multiple rollers 220 are rotatably mounted on the vertical plate 211 along the length of the guide rail 210. The multiple rollers 220 are arranged in parallel, and the guide rail 210 is driven to rotate synchronously by the constant-speed motor 230 via a chain. The torque limiter 240 is installed between the output shaft of the constant speed motor 230 and the drive shaft of the chain. When the constant speed motor 230 is working, it will synchronously drive multiple rollers 220 to rotate at a constant speed through the chain. When the rollers 220 are resisted by the carbon blocks, once the resistance of the rollers 220 exceeds the limit of the torque limiter 240, the torque limiter 240 will interrupt the transmission between the output shaft of the constant speed motor 230 and the chain. At this time, the constant speed motor 230 will run idle, and the rollers 220 and the carbon blocks will be relatively stationary.

[0038] To increase the friction between the roller 220 and the carbon block, a wear-resistant coating 221 is sprayed onto the surface of the roller 220 to form a protective layer. The protective layer can form a conveying surface with a high coefficient of friction on the surface of the roller 220, thereby reducing the probability of slippage between the carbon block and the roller 220.

[0039] Reference Figure 4 and Figure 5 The damping plate assembly 100 includes a top plate 110, a bottom plate 120, a spring 130, and adjusting bolts 140. The bottom plate 120 is made of sheet metal and is fixedly connected to the guide rail 210 by bolts. Six spring limiting posts 111 are welded onto the upper surface of the bottom plate 120. The lower half of the spring 130 is fitted onto the spring limiting posts 111 on the bottom plate 120. The six spring limiting posts 111 are arranged in two rows on both sides of the bottom upper surface, and four guide holes 121 are also provided on the bottom. Six spring limiting posts 111 are provided on the lower surface of the top plate 110, and six spring limiting posts 140 are provided on the top plate 110. Each spring limiting post 111 is correspondingly set with one of the six locking slots on the base plate 120. The upper part of the spring 130 is sleeved on the spring limiting post 111 below the top plate 110. Four guide rods 112 are also welded to the lower surface of the top plate 110. The four guide rods 112 on the top plate 110 are respectively corresponding to the four guide holes 121 on the base plate 120. The spring limiting posts 111 on the top plate 110 and the base plate 120 are also provided with through positioning holes. The adjusting bolt 140 passes through the positioning hole of the top plate 110 and into the positioning hole of the base plate 120 to fix the top plate 110 and the base plate 120.

[0040] During installation, first, the lower half of the spring 130 is fitted onto the spring limiting post 111 of the base plate 120. Then, the top plate 110 is placed above the spring 130, and the upper half of the spring 130 is fitted onto the spring limiting post 111 on the top plate 110. The guide post on the top plate 110 is then inserted into the guide hole 121 on the base plate 120 to limit the vertical movement of the top plate 110 and the base plate 120. Finally, the adjusting bolt 140 is inserted into the fixing holes of the top plate 110 and the base plate 120 to fix the top plate 110 and the base plate 120. At the same time, the adjusting bolt 140 is tightened to compress the spring 130, so that the top plate 110 and the base plate 120 are in a relatively stable state. The relative height between the top plate 110 and the base plate 120 can also be adjusted during the adjustment of the adjusting bolt 140.

[0041] Reference Figure 4 To increase the service life of the top plate 110, a wear-resistant layer 113 made of 42CrMo material is also provided on the upper surface of the top plate 110. At the same time, in order to make the carbon block contact the upper surface of the top plate 110 more stably, a guide surface 114 is also provided on the upper surface of the top plate 110. The guide surface 114 is a cut surface formed by cutting on both sides of the top plate 110. The cut surface forms a 30-degree angle with the side of the top plate 110. When the carbon block moves above the top plate 110, it will move along the cut surface to the top of the top plate 110.

[0042] When the carbon block moves above the top plate 110 and applies pressure to the top plate 110, the guide rod 112 slides vertically along the guide hole 121, reducing the lateral offset between the top plate 110 and the bottom plate 120. During the relative movement of the top plate 110 and the bottom plate 120, the spring 130 continuously provides an upward preload, keeping the top plate 110 in contact with the carbon block. When the top plate 110 wears down and its height decreases, loosening the adjusting bolt 140 allows the top plate 110 to move automatically upward under the action of the spring 130, maintaining a constant frictional force between the top plate 110 and the carbon block.

[0043] The implementation principle of a spring-type carbon block damping system for a casting station according to this utility model embodiment is as follows:

[0044] During the operation of the casting station, the carbon block moves along the direction of the guide rail 210 to the casting station on the roller 220. When the carbon block moves to the casting station, the roller 220 rotates at a constant speed under the drive of the directional motor, which causes the carbon block to move at a constant speed on the guide rail 210. Then, under the drive of the constant speed motor, it moves along the guide surface 114 of the top plate 110 to above the top plate 110. After the carbon block moves to above the top plate 110, the bottom of the carbon block rubs against the upper surface of the top plate 110, causing the carbon block to gradually stop moving and stop at the casting station. After the carbon block stops at the casting station, the roller 220 connected to the constant speed motor 230 is relatively stationary with the carbon block, which causes the torque of the output shaft of the constant speed motor 230 to increase. The torque limiter 240 disengages the transmission between the constant speed motor 230 and the roller 220, reducing the wear between the roller 220 and the bottom of the carbon block.

[0045] In summary, this application, by setting an adjusting bolt 140 and a spring 130, allows for flexible adjustment of the height of the top plate 110 through their cooperation, thereby adjusting the friction between the damping plate and the bottom of the carbon block, enabling the carbon block to stop more accurately at the casting station. By setting a constant-speed motor 230 to drive the roller 220 to rotate, the roller 220 provides a stable moving speed for the carbon block as it moves, reducing the impact of speed fluctuations on the positioning accuracy of the carbon block and further improving the accuracy of the carbon block's stopping position. Furthermore, a torque reducer is provided to interrupt the power transmission between the constant-speed motor 230 and the roller 220 when the carbon block stops moving, causing the roller 220 to stop rotating under the friction of the carbon block, reducing wear between the roller 220 and the carbon block, and extending the service life of the device.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
