Description

Technical Field

[0001] This invention relates to the field of irregular part forging technology, specifically to an irregular part forging device for large machinery. Background Technology

[0002] Large, irregularly shaped mechanical parts, such as wind turbine main shafts and nuclear power plant rotors, are core components of critical equipment, and their forging quality is of paramount importance. Currently, these large, irregularly shaped parts are mainly produced using free forging technology, which requires the billets to be heated at high temperatures for extended periods. This results in the formation of a large amount of iron oxide scale on the surface of the billets during forging, leading to a series of quality problems.

[0003] During forging, the hard and brittle oxide scale is pressed into the metal matrix, forming pits and depressions, severely damaging the surface quality and dimensional accuracy of the forging. If the defects exceed the machining allowance, the workpiece will be scrapped. Oxide scale coverage makes dimensional measurements inaccurate, leading to increased machining allowances for safety, resulting in low material utilization and high costs. In addition, oxide scale accelerates die wear, interferes with non-destructive testing, masks true defects, and creates safety hazards.

[0004] Existing cleaning methods mainly rely on pre-forging high-pressure water descaling or manual cleaning, which have problems such as low efficiency, unstable results, and inability to achieve continuous automated operation. Especially for large irregular parts with complex surfaces that require multiple heating deformations, it is difficult to ensure surface cleanliness before each critical step of the forging process.

[0005] Therefore, it is necessary to provide a forging device for irregularly shaped parts for large machinery to solve the above problems. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-9The present invention provides a technical solution: a forging device for irregularly shaped parts of large machinery, comprising a forging machine 1, two sets of protective mechanisms 2, two sets of dust removal mechanisms 3, two sets of cleaning mechanisms 4, and two sets of cameras 5. The protective mechanisms 2, dust removal mechanisms 3, cleaning mechanisms 4, and cameras 5 are all mounted on the forging machine 1. The two sets of protective mechanisms 2 are respectively mounted on both sides of the long side of the forging machine 1. The two sets of dust removal mechanisms 3 are respectively mounted on the side of the two sets of protective mechanisms 2 that are close to each other. The two sets of cleaning mechanisms 4 and the two sets of cameras 5 are respectively mounted on both sides of the short side of the forging machine 1. The two sets of cameras 5 are located between the two sets of cleaning mechanisms 4. The protective mechanisms 2 are used to close the forging machine 1 when forging the billet. The dust removal mechanisms 3 are used to blow away and adsorb iron oxide scale. The cleaning mechanisms 4 are used to mechanically remove iron oxide scale from the surface of the billet. The cameras 5 are used to capture the forging process of the billet to determine whether the iron oxide scale on the surface of the billet has been cleaned.

[0037] Specifically, such as Figure 1 As shown, the forging machine 1 is equipped with a forging zone, two sets of inlets and outlets, and two sets of equipment zones. The two sets of inlets and outlets are located on the front and rear sides of the forging zone and are connected to the forging zone. The orientation of the two sets of inlets and outlets is parallel to the short side of the forging machine 1. The two sets of equipment zones are located on the left and right sides of the forging zone and are connected to the forging zone. The orientation of the two sets of equipment zones is parallel to the long side of the forging machine 1.

[0038] Specifically, such as Figures 1-3 As shown, the protective mechanism 2 includes cylinder 21, protective door 22, and cylinder 27. Cylinder 21 is fixed to the top center of the long side wall of the forging machine 1, located above the inlet and outlet. Protective door 22 is fixed to the bottom of the output end of cylinder 21. Two sets of limiting wheels 23 are fixedly connected to the side of cylinder 21. The two sets of limiting wheels 23 are located on both sides of the protective door 22. The two sets of limiting wheels 23 are connected to the bearings on both sides of the protective door 22. Each set of limiting wheels 23 has two parts, located at the top and bottom of the side wall of the protective door 22, respectively. The limiting wheels 23 and the limiting post 24 form a limiting position.

[0039] Two sets of connecting blocks 25 are fixedly connected to the top edge of the protective door 22. The top of the limiting block 26 is fixedly connected to the limiting block 26. A limiting chamber is set in the middle of the limiting block 26. The cylinder 27 is fixed to the side of the limiting block 26 away from the forging machine 1. The output end of the limiting block 26 is fixedly connected to the limiting rod 28. A limiting groove 29 is set on the limiting block 26. The position, shape and size of the limiting groove 29 match those of the limiting rod 28.

[0040] In actual operation, after the billet is placed into the forging machine 1 from the long side, cylinder 21 extends, driving the protective door 22 to descend. The limiting wheels 23 on both sides of the protective door 22 roll on the surface of the limiting post 24, which improves the stability of the protective door 22 during descent. When cylinder 21 is fully extended, the protective door 22 closes the inlet and outlet, forming a relatively enclosed space in the forging area. This prevents the iron oxide scale on the billet from splashing due to the impact of the forging machine 1 on the billet during the forging process, which would affect the environment and create safety hazards. At the same time, the protective door 22 can isolate the noise generated by the forging of the billet inside the forging machine 1 to a certain extent, reducing noise.

[0041] Specifically, such as Figures 4-7 As shown, the dust removal mechanism 3 includes two sets of air pipes 32 and one set of adsorption chambers 36. Two sets of support plates 31 and 35 are fixedly connected to the side of the dust removal mechanism 3. The second support plate 35 is located between the two sets of support plates 31. The two sets of air pipes 32 are respectively set on the side of the two sets of support plates 31 that are close to each other. The air pipes 32 are connected to the support plates 31 by bearings. One end of the air pipe 32 is connected to a fan and an air source through a pipeline. A motor 34 is fixedly connected to the support plate 31. The motor 34 is connected to the air pipe 32 by a pulley drive. Several nozzles 33 are connected to the air pipe 32.

[0042] The adsorption chamber 36 is fixed to the side of the support plate 35. Several adsorption chambers 36 are provided on the adsorption chamber 36. One end of the adsorption port 37 is connected to a vacuum pump through a pipeline. A filter is provided on the pipeline connecting the adsorption port 37 and the vacuum pump.

[0043] It should be noted that the gas source can be selected according to actual needs, and can be clean compressed air or inert gas; on the pipeline connecting the gas pipe 32 and the compressed air, a temperature regulation device can be set according to actual needs. It can be a cooler to cool down the gas entering the gas pipe 32, reduce the temperature around the forging machine 1, increase the cooling rate of the billet, and reduce the subsequent cooling time of the billet; or it can be a heater to heat up the gas entering the gas pipe 32 to avoid the temperature around the forging machine 1 being too low, the billet cooling rate being too fast, and the formation of more iron oxide scale.

[0044] In actual operation, the motor 34 starts and drives the air pipe 32 to rotate through gear transmission, adjusting the direction of the nozzle 33. Then the fan starts and introduces air into the nozzle 33, which blows out to remove the iron oxide scale from the target area, reducing the labor intensity of manual cleaning by the staff. The exhaust fan starts and can adsorb the dust and debris raised during the process of blowing away the iron oxide scale and collect it by the filter, preventing the dust and debris from spreading and reducing the quality of the surrounding environment.

[0045] Specifically, such as Figure 6 and Figure 8As shown, the cleaning mechanism 4 includes a dual-axis moving base 41, a cylinder 45, and a fan wheel 46. The dual-axis moving base 41 is fixed to the short side of the forging machine 1. A drive base 42 is provided on the dual-axis moving base 41. The dual-axis moving base 41 is used to drive the drive base 42 to move back and forth along the short side of the forging machine 1 and to move up and down in the height direction. A rotating cylinder 43 is connected to the drive base 42 by a bearing. A motor 44 is fixedly connected to the top of the drive base 42. The motor 44 is gear-driven to the rotating cylinder 43. The cylinder 45 is located inside the rotating cylinder 43. The output end of the cylinder 45 passes through the rotating cylinder 43 and is fixedly connected to the fan wheel 46. Several bristles 47 are fixedly connected to the fan wheel 46. The fan wheel 46 is located in the equipment area.

[0046] A support base 48 is provided in the equipment area. The support base 48 is fixedly connected to the forging machine 1. A cylinder 49 is fixedly connected to the side of the support base 48. The output end of the cylinder 49 passes through the support base 48. A push plate 410 is fixedly connected to the output end of the cylinder 49.

[0047] In actual operation, the dual-axis moving seat 41 is started, driving the drive seat 42 to move back and forth along the short side of the forging machine 1 and up and down in the height direction. The extension and retraction of cylinder 3 45 is used to adjust the left and right movement of the billet in the length direction of the forging machine 1, thereby adjusting the spatial position of the fan wheel 46 and the brush 47 in the forging area. Then, motor 2 44 is started, driving the rotating cylinder 43 to rotate through gear transmission, which in turn drives cylinder 3 45 and the fan wheel 46 and brush 47 at the end of cylinder 3 45 to rotate. The brush 47 cleans the surface of the billet. The fan wheel 46 is used to provide support for the brush 47 to clean the iron oxide scale. When the brush 47 is completely deformed, it can also be attached to the fan wheel 46. At this time, the rotating brush 47 can still continue to clean the iron oxide scale on the surface of the billet.

[0048] Specifically, such as Figure 9 As shown, a camera 5 is installed in the equipment area. The camera 5 is located above the support base 48 and is fixedly connected to the forging machine 1. The camera 5 is used to capture the forging process of the billet. The camera 5 is connected to an identification and analysis module. The identification and analysis module is electrically connected to the protection mechanism 2, the dust removal mechanism 3, and the cleaning mechanism 4. The identification and analysis module is used to acquire the forging images captured by the camera 5 and analyze the cleaning status of the iron oxide scale on the surface of the billet. Then, it controls the protection mechanism 2, the dust removal mechanism 3, and the cleaning mechanism 4 to perform corresponding operations to remove the iron oxide scale on the surface of the billet.

[0049] Specifically, such as Figure 9 As shown, recycling boxes 6 are provided on the front and rear sides of the forging machine 1. The recycling boxes 6 are located below the inlet and outlet and are used to collect iron oxide scale generated during the forging process.

[0050] Working principle of forging equipment for irregularly shaped parts in large machinery:

[0051] S1: Ready state: The cylinders 21 of the two sets of protective mechanisms 2 retract, driving the protective door 22 to the highest point to ensure that the entrance and exit are fully open. At the same time, the cylinder 27 may start to extend, pushing the limit rod 28 into the limit slot 29 to form a mechanical lock and prevent the protective door 22 from falling accidentally.

[0052] The motor 37 of the dust removal mechanism 3 starts, driving the air pipe 32 to rotate and adjusting the initial angle of the nozzle 33. The initial angle is set manually.

[0053] The retraction of the dual-axis moving seat 41 and cylinder 45 of the cleaning mechanism 4 allows the fan wheel 46 and brush bristles 47 to be located within the equipment area, preventing interference with the entry of the blank.

[0054] S2: Loading: An external trolley or conveyor feeds the preheated hot billet into the forging zone of the forging machine through the front inlet and outlet. The cylinders 49 on both sides of the equipment zone extend, driving the two sets of push plates 410 to move closer to each other, making fine adjustments to the billet and ensuring that it is in a standard initial position, preparing it for subsequent automated cleaning and forging.

[0055] S3: Closure: Cylinder 27 retracts, causing the limit rod 28 to release its restriction on the protective door 22. Cylinder 21 of the protective mechanism 2 extends, driving the protective door 22 to descend. During the descent, the limit wheel 23 rolls along the limit post 24 to ensure that the door is stable and does not shake. At this time, the forging area forms a relatively closed space, preparing for subsequent operations.

[0056] S4: Forging: The main press of forging machine 1 forges the billet. Under the huge pressure, the billet deforms, and the iron oxide scale on its surface cracks and loosens due to the different shrinkage rate of the billet and the base metal.

[0057] S5: Iron Oxide Scale Detection: At the moment the forging head is lifted, the identification and analysis module acquires the image of the billet surface captured by camera 5, and identifies the maximum single area, total coverage percentage, and distribution location of the bright red billet substrate and the dark red and black iron oxide scale. The maximum single area is denoted as S. i-max The total coverage percentage is denoted as ω. i-总 , i∈[1,N], N is the total stage number of forging, N is a positive integer.

[0058] The identification and analysis module is equipped with a maximum single area threshold for determining the size of a single iron oxide scale and a percentage threshold for determining the total amount of iron oxide scale. The maximum single area threshold is denoted as S. i-max The percentage threshold is denoted as ω. i-总 'In S i-max >S i-max At ω, the area of ​​unpeeled iron oxide scale is large. i-总 >ω i-总At that time, there was mostly unpeeled iron oxide scale.

[0059] When S i-max ≤S i-max 'and ω i-总 ≤ω i-总 At this time, the iron oxide scale on the billet is small and minimal, indicating normal iron oxide removal during forging. The iron oxide scale on the billet surface will not affect normal forging. i-max =0 and ω i-总 =0 is the ideal state.

[0060] When S i-max ≤S i-max '、ω i-总 >ω i-总 At this time, the iron oxide scale on the billet is small but numerous. During the forging process, the amount of iron oxide scale produced is small, the iron oxide scale is loose and not easy to peel off, and air blowing is required for cleaning.

[0061] When S i-max >S i-max '、ω i-总 ≤ω i-总 At this time, the iron oxide scale on the billet is large but not numerous, and the local temperature abnormality of the billet makes it difficult to peel off the iron oxide scale, requiring local cleaning.

[0062] When S i-max >S i-max '、ω i-总 >ω i-总 At this time, the iron oxide scale on the billet is large and numerous, which is caused by the large temperature difference between the billet and the environment. This results in a large amount of iron oxide scale being produced, but the high temperature of the billet makes the iron oxide scale difficult to remove, requiring mixing and cleaning.

[0063] S6: Iron oxide scale cleaning: Based on the analysis results, the identification and analysis module intelligently controls the dust removal mechanism 3 and the cleaning mechanism 4 to start different iron oxide scale cleaning methods.

[0064] Air blowing cleaning: The identification and analysis module controls the two sets of motors 34 of the dust removal mechanism 3 to start, driving the air pipe 32 to rotate, aiming the two sets of nozzles 33 at the identified iron oxide scale accumulation area, and controlling the fan and air source to start. High-pressure airflow is sprayed out from the nozzles at high speed, blowing the loose iron oxide scale away from the surface of the billet; at the same time, the exhaust fan starts, and the adsorption port 37 generates a strong suction force, instantly sucking the raised iron oxide scale dust into the adsorption chamber 36, which is then collected by the filter to prevent dust from escaping; at the same time, the identification and analysis module controls the operation of the cooler on the pipeline connecting the air pipe 32 and the compressed air to cool the gas entering the air pipe 32, reduce the temperature around the forging machine 1, increase the cooling rate of the billet, and promote the cooling and peeling off of the iron oxide scale on the surface of the billet.

[0065] Local cleaning: The identification and analysis module controls the dual-axis moving seat 41 to start and the cylinder 3 45 to extend and retract, driving the fan wheel 46 and brush bristles 47 to move in the three-dimensional space of the forging area. The distance between the brush bristles 47 and the surface of the billet is adjusted to accurately position the surface to be cleaned, while ensuring that the contact pressure is moderate. Then, the motor 2 44 is started, and the rotating cylinder 43 is driven to rotate through gear transmission, which in turn drives the fan wheel 46 and brush bristles 47 to rotate, so that the hard brush bristles 47 scrape and brush the surface of the billet, thoroughly removing the firmly attached iron oxide scale.

[0066] Hybrid cleaning: The identification and analysis module controls the air blowing cleaning and performs local cleaning on the basis of air blowing cleaning. During the process, the dual-axis moving seat 41 is continuously in the starting state and the cylinder 3 45 is continuously in the extension and retraction state, so that the fan wheel 46 and brush 47 move in the three-dimensional space of the forging area to scrape and brush the surface of the billet in all directions. At the same time, the identification and analysis module controls the heater on the pipeline connected to the compressed air pipe 32 to start, so as to heat up the gas entering the air pipe 32, increase the temperature around the forging machine 1, slow down the cooling rate of the iron oxide scale of the billet, thereby reducing the amount of iron oxide scale formed and reducing the difficulty of iron oxide scale cleaning.

[0067] S7: Re-test: After cleaning, the camera will be tested again. If S7 still exists... i-max >S i-max 'or ω i-总 >ω i-总 If the error occurs, the identification and analysis module will issue an alarm, and staff will assist in the cleanup.

[0068] S8: Multi-pass forging and intermittent cleaning: Repeat the cleaning cycle of S4-S7 until all passes of the entire forging process are completed.

[0069] S9: Post-forging treatment and workpiece unloading: After all forging processes are completed, the identification and analysis module activates the mixed cleaning mode of the dust removal mechanism 3 to promote the flow of gas around the billet, increase the cooling rate of the billet, and at the same time perform a comprehensive surface cleaning of the billet to ensure a smooth surface of the finished product.

[0070] After cleaning, the identification and analysis module controls cylinder 21 to lift the protective door 22, opening the inlet and outlet. Cylinder 27 extends, causing the limit rod 28 to continue to limit the protective door 22. The external trolley or conveyor takes away the forged billet. Then, the two sets of cylinders 49 extend, pushing the two sets of push plates 410 closer together, pushing the iron oxide scale to the middle of the forging area. Then, the module controls the local cleaning mode, so that the two sets of brush bristles 47 come into contact with each other, achieving self-cleaning of the two sets of brush bristles. At the same time, the fan wheel 46 and brush bristles 47, which move and rotate in three-dimensional space in the forging area, can push all the fallen iron oxide scale into the recycling box 6 for centralized recycling and processing.

[0071] The above methods enable the automatic cleaning and collection of iron oxide scale during the forging process of large billets, thereby improving the forging quality and efficiency of billets and reducing the labor intensity of workers.
