Description

Technical Field

[0001] The present invention relates to the technical field of forging processing, and specifically relates to an automatic oxide scale cleaning device for improving the surface quality of shaft forgings. Background Art

[0002] Forgings are workpieces or blanks obtained by forging deformation of metal billets, and are divided into cold forging, warm forging and hot forging. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. Among them, a large amount of oxide scale will appear on the surface of the workpiece during hot forging processing. During the forging process, part of the oxide scale will fall off, and some oxide scale adheres to the forging, which needs to be cleaned.

[0003] The commonly used cleaning method is that the operator manually cleans with tools, which is time-consuming and laborious, and the effect is also poor. An oxide scale cleaning machine for pipe forgings with the patent publication number CN210358250U mainly includes a frame, a workbench, a motor, a gearbox, a transmission shaft and other structures, and a cylinder and a scraper mounting bracket and a scraper are connected to the bottom of the transmission shaft; the pipe forging is conveyed to the workbench through the feed port and the conveyor belt, and the oxide on the outer surface of the forging is processed by the scraper.

[0004] Although the above-mentioned cleaning machine can clean the circumferential surface of the forging, the position of the forging is fixed and there is no turning structure, resulting in inconvenient turning of the pipe fitting. During cleaning, only the scraper is used for cleaning, the cleaning structure is single, and the effect is poor.

[0005] Based on this, the present invention designs an automatic oxide scale cleaning device for improving the surface quality of shaft forgings to solve the above problems. Summary of the Invention

Detailed implementation manners

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0057] Embodiment 1. Please refer to the accompanying drawings. The present invention provides a technical solution:

[0058] An automatic scale cleaning device for improving the surface quality of shaft forgings, as Figure 1 shown, includes a base 100. At both ends of the top surface of the base 100, end plates 103 are symmetrically fixed. A moving mechanism 200 is arranged between the two end plates 103, and a fixing frame 400 is arranged in the middle of the top of the base 100;

[0059] On both sides of the top surface of the base 100, two bosses 101 are symmetrically fixed. The two ends of the bosses 101 are located at the end plates 103, and a collecting groove 102 is arranged between the two bosses 101. The two bottom ends of the fixing frame 400 are respectively fixed to the middle parts of the outer sides of the bosses 101;

[0060] As Figure 7 、 8 shown, a plurality of lifting cylinders 403 are evenly arranged on the top of the fixing frame 400, and a lifting plate 404 is jointly fixed to the bottom ends of the plurality of lifting cylinders 403. Along the length direction of the base 100 at the bottom of the lifting plate 404, a knocking assembly 500, a shoveling assembly 600, and a cleaning assembly 700 are arranged in sequence;

[0061] As Figure 2 shown, a moving mechanism 200 is arranged on the top of the boss 101. A support rotating mechanism 300 is connected to the moving mechanism 200. The support rotating mechanism 300 includes an adjusting seat 204 connected to the moving mechanism 200. Two support boxes 304 and two support plates 303 are arranged on the top of the adjusting seat 204, and a support shaft 302 is rotatably connected through the support plates 303 and the support boxes 304. A plurality of support wheels 301 are evenly fixed on the support shaft 302, and a guide plate 205 inclined inward is jointly fixed on the support plates 303 and the support boxes 304;

[0062] A cavity is arranged inside the adjusting seat 204. The bottom end of the support box 304 is communicated with the adjusting seat 204, and a transmission assembly is arranged in the adjusting seat 204. A rack 105 is arranged between the two end plates 103. The rack 105 passes through the adjusting seat 204, and the support shaft 302 is correspondingly connected to the rack 105 through the transmission assembly.

[0063] When transporting the forging, the forging is placed on the two support rotating mechanisms 300 and located on the support wheels 301 on both sides. The position of the support wheels 301 can be adjusted by the movement of the adjusting seat 204, so as to adjust the distance between the support wheels 301 on both sides, and then jack up the shaft forging or lower the position of the forging, adjust the position of the shaft forging, and avoid situations such as too high or too low position of the shaft forging, so as to adapt to the lifting range of structures such as the knocking assembly 500, and the lifting of structures such as the knocking assembly 500 is realized through the lifting cylinder 403 and the lifting plate 404.

[0064] After the forging is placed in place, the moving mechanism 200 drives the adjusting seat 204 to drive the supporting wheel 301 and the shaft forging to move towards the fixing frame 400. During the movement, the shaft forging and the supporting wheel 301 move relative to the rack 105. Furthermore, the driving assembly enables the supporting shaft 302 to drive the supporting wheel 301 and the forging to rotate, so that when passing through the fixing frame 400, the circumferential surface of the shaft forging is successively subjected to operations such as knocking treatment, scale removal, and forging surface cleaning by the knocking assembly 500, the material shoveling assembly 600, and the cleaning assembly 700, thereby improving the forging surface cleaning effect.

[0065] In the present invention, the moving mechanism 200 enables the supporting and rotating mechanism 300 and the forging to move synchronously, and during the movement, the forging is driven to rotate through the driving assembly and the rotation of the supporting wheel 301, making the forging surface cleaning more comprehensive. Moreover, the movement of the forging is consistent with that of the supporting wheel 301, reducing the damage to structures such as the supporting wheel 301.

[0066] In the present invention, the knocking assembly 500 knocks the scale on the surface of the shaft forging, causing the scale to loosen or even be easily detached relative to the shaft forging, making the subsequent cleaning faster and more convenient. The material shoveling assembly 600 shovels and cleans the remaining scale after knocking, making the scale cleaning more thorough. After the scale cleaning is completed, the cleaning assembly 700 further cleans the fine fragments and dust adhering to the end face surface, improving the forging surface quality.

[0067] The present invention can adjust the position of the supporting wheel 301 and can also adjust the height position of structures such as the knocking assembly 500, thereby expanding the application range of the equipment. During the cleaning process, the guide plate 205 guides the cleaned materials for downward feeding and drops them into the aggregate tank 102, facilitating subsequent recycling and processing.

[0068] Among them, as Figure 2 、 3 shown, the moving mechanism 200 includes a moving seat 201 slidably connected to the top surface of the boss 101. A screw rod 202 is threadedly connected in the moving seat 201. The two ends of the screw rod 202 are rotatably connected to the end plates 103 on both sides. One end of the screw rod 202 is connected with a transmission belt pulley 206. The two transmission belt pulleys 206 are connected by a transmission belt. And one end of one of the screw rods 202 is connected with a motor. A plurality of adjusting hydraulic cylinders 203 are evenly arranged inside the moving seat 201, and the outer side surface of the adjusting seat 204 is correspondingly connected with the plurality of adjusting hydraulic cylinders 203.

[0069] When it is necessary to move the shaft forging, through the drive of the motor and the transmission of the belt pulley 206, the two screws 202 rotate simultaneously, so that the moving seats 201 on both sides move simultaneously, and drive structures such as the adjusting seat 204 and the supporting wheel 301 to move, thereby moving the shaft forging to realize the conveying of the shaft forging; the position of the adjusting seat 204 and the supporting wheel 301 can be adjusted by adjusting the hydraulic cylinder 203 to adjust the position of the shaft forging.

[0070] Among them, as Figure 5 shown, the transmission component includes two first belt pulleys 305 fixed on the support shaft 302, and the two first belt pulleys 305 are respectively located inside the two support boxes 304. A second belt pulley 306 is connected below the first belt pulley 305 through a transmission belt. The second belt pulley 306 is rotatably connected to the inner cavity of the adjusting seat 204 and coaxially fixed with a first bevel gear 307. As Figure 6 shown, a second bevel gear 308 is meshed with one side of the first bevel gear 307. The second bevel gear 308 is rotatably connected to the inner side wall of the adjusting seat 204, and a moving gear 309 is coaxially fixed at the bottom. The moving gear 309 is meshed with the rack 105;

[0071] As Figure 4 shown, a sliding groove 104 is fixed on the inner side of the end plate 103 corresponding to the position of the rack 105. The end of the rack 105 is slidably connected to the sliding groove 104, and one side of the sliding end is connected to one end of the sliding groove 104 through a spring. When the adjusting seat 204 moves, the rack 105 can adjust its position accordingly and remain meshed with the moving gear 309.

[0072] When structures such as the adjusting seat 204 and the supporting wheel 301 move, the moving gear 309 moves relative to the rack 105, so that the moving gear 309 rotates, and through the transmission of the first bevel gear 307 and the second bevel gear 308, the first belt pulley 305 and the second belt pulley 306, the support shaft 302 drives the supporting wheel 301 to rotate, so as to drive the shaft forging to rotate during the movement to clean the scale of the shaft forging; in order to ensure the same rotation direction of the two supporting wheels 301, the front and rear positions of structures such as the first bevel gear 307 in the two supporting rotation mechanisms 300 relative to the second belt pulley 306 can be adjusted.

[0073] Among them, as Figure 9 shown, the knocking component 500 includes a first knocking plate 501 located below the lifting plate 404. The two sides of the first knocking plate 501 are symmetrically inclined, and two first knocking seats 502 are symmetrically fixed at the bottom. As Figure 10As shown, two first spring frames 503 are symmetrically fixed on the top surface of the first knocking plate 501, the top of the first spring frame 503 passes through the lifting plate 404, and is fixed with a horizontal first spring plate 504, and the top of the first spring plate 504 is connected to the top of the fixing frame 400 through a spring;

[0074] like Figure 11 As shown, two rotating seats are symmetrically fixed at the position corresponding to the top of the lifting plate 404 between the two first spring frames 503, and two parallel rotating frames 506 are rotatably connected to each rotating seat, and a first gear 507 is coaxially fixed to the rotating connection of one of the rotating frames 506, and a driving wheel 505 is fixed to the other end of the rotating frame 506. The two driving wheels 505 on the same rotating seat are located at the bottom of the same first spring plate 504, and a rotating groove 407 is provided at the position of the lifting plate 404 corresponding to the driving wheel 505 and the rotating frame 506, and the two first gears 507 are meshed with second gears 508, and the two second gears 508 are meshed with each other and rotatably connected to the top of the lifting plate 404, and one of the second gears 508 is connected to a motor.

[0075] When the shaft forging moves to the bottom of the knocking assembly 500, the rotating frames 506 on both sides are rotated through the drive of the motor and the transmission of the first gear 507 and the second gear 508, and the driving wheel 505 is driven to move. In the process of the rotating frame 506 and the driving wheel 505 rotating upward, the driving wheel 505 drives the first spring plate 504 to move upward, thereby driving the first spring frame 503 and the first knocking plate 501 and other structures to move up a certain distance; when the driving wheel 505 continues to rotate, its position is staggered with the position of the first spring plate 504, As a result, the first spring plate 504 moves downward rapidly under the action of the spring return and the gravity of the first knocking plate 501 and other structures, so that the first knocking seat 502 knocks the surface of the shaft forging, so that the oxide scale can loosen or even fall off relative to the surface of the shaft forging, which is convenient for subsequent further cleaning; during the rotation of the rotating frame 506, the pushing wheel 505 repeatedly contacts, lifts up, and disengages from the first spring plate 504, so that the first knocking seat 502 repeatedly rises and falls, and the shaft forgings are fully knocked during the movement and rotation process.

[0076] Among them, Figure 9 As shown, the shovel assembly 600 includes a first shovel plate 601 located in the middle below the lifting plate 404. Figure 12 As shown, the top of the first shovel plate 601 passes through the lifting plate 404 and is fixed with a moving plate 602. Figure 13 As shown, the two sides of the bottom of the movable plate 602 are connected to the top surface of the lifting plate 404 through springs, and the first electromagnet 603 is fixed at the corresponding positions of the bottom of the movable plate 602 and the top of the lifting plate 404, and the first electromagnet 603 is electrically connected to a power supply and a switch.

[0077] When the shaft forging is about to move below the first shovel plate 601, the first electromagnet 603 is electrified and repels, causing the moving plate 602 to stretch the spring and drive the first shovel plate 601 to move upward, so as to leave a certain distance for the shaft forging to smoothly move below the first shovel plate 601. Then the first electromagnet 603 is powered off, and the moving plate 602 drives the first shovel plate 601 to move downward under the action of the spring and contacts the top of the shaft forging, so as to remove the scale on its surface during the movement and rotation of the shaft forging.

[0078] Among them, as Figure 9 shown, the cleaning assembly 700 includes a first cleaning plate 701 located below the lifting plate 404. The two sides of the first cleaning plate 701 are symmetrically inclined, and cleaning bristles 702 are evenly distributed on both sides of the bottom. As Figure 14 shown, two vertical second spring brackets 704 are symmetrically fixed on both sides of the top of the first cleaning plate 701. The top ends of the second spring brackets 704 pass through the lifting plate 404 and are fixed with a horizontal second spring plate 705. The top of the second spring plate 705 is connected to the top of the fixed frame 400 through a spring, and second electromagnets 706 are provided at the corresponding positions on the bottom of the second spring plate 705 and the lifting plate 404. The second electromagnets 706 are electrically connected to a power supply and a switch.

[0079] When the shaft forging approaches the cleaning assembly 700, the second electromagnets 706 are electrified and repel, causing the second spring plate 705 to compress the spring and drive the second spring brackets 704 and the first cleaning plate 701 to move upward, so that the shaft forging can smoothly move below the first cleaning plate 701. Then the second electromagnets 706 are powered off, and the first cleaning plate 701 moves downward under the action of the spring and its own weight, and contacts the shaft forging through the cleaning bristles 702, so as to further clean the forging during the movement and rotation of the shaft forging and improve the cleaning effect on the surface of the forging.

[0080] Embodiment 2. The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that, as Figure 7 shown, a pump body 401 is provided on the fixed frame 400. A water inlet pipe 402 is provided on one side of the pump body 401. The water inlet pipe 402 is arranged along the outside of the fixed frame 400, and the bottom end passes through one of the bosses 101 and extends into the aggregate tank 102. A water outlet pipe 406 is provided at the bottom of the pump body 401. As Figure 15As shown in the figure, a water spray pipe 707 is provided at the top of the first cleaning plate 701. The water outlet pipe 406 is connected to the water spray pipe 707, and the water outlet pipe 406 is set as a telescopic pipe or a hose with a longer length so as to be able to cooperate with the movement of the first cleaning plate 701. A plurality of nozzles 703 are evenly provided at the bottom of the water spray pipe 707, and the nozzles 703 pass through the middle position of the first cleaning plate 701. Water is filled in the aggregate tank 102. Through the pump body 401 and the water inlet pipe 402, the water enters the water spray pipe 707 through the water outlet pipe 406 and is sprayed out through the nozzles 703, so as to perform spray flushing treatment and cooling on the forging while the cleaning brush hairs 702 are cleaning, thereby improving the cleaning effect.

[0081] Embodiment 3. The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that, as Figure 7 shown, an end face cleaning mechanism is provided on one side of the fixing frame 400, and the end face cleaning mechanism is located outside the cleaning assembly 700. The end face cleaning mechanism includes a mounting plate 405 fixed to the middle of the top of the fixing frame 400. A central shaft 802 is rotatably connected to the middle of the bottom of the mounting plate 405. The inner end of the central shaft 802 is connected with a motor, and the outer end is fixed with a rotating rod 801. The bottom end of the rotating rod 801 is fixed with a rotating box 800. As Figure 16 shown, second knocking plates 804 are provided in the middle of both sides of the rotating box 800. Second knocking seats 805 are fixed on the outer side surfaces of the second knocking plates 804, and a vibration assembly is provided between the two second knocking plates 804. A second shoveling plate 803 is provided on one side of the second knocking plate 804, and a second cleaning plate 806 is provided on the other side. Both the second shoveling plate 803 and the second cleaning plate 806 are connected to the rotating box 800 through a telescopic structure. Brush hairs are evenly distributed on the outer side surface of the second cleaning plate 806.

[0082] When the end face of the shaft forging approaches the end face cleaning mechanism, the motor is used to rotate the rotating rod 801 and the rotating box 800 from one side above the base 100 to the other side. During the rotation process, the second knocking plates 804 and the second knocking seats 805 are vibrated through the vibration assembly and come into contact with the end face of the forging for knocking treatment. During the knocking treatment process, the second shoveling plate 803 and the second cleaning plate 806 do not come into contact with the end face of the shaft forging;

[0083] When the knocking treatment is completed, the rotating rod 801 and the rotating box 800 rotate back. During the rotation back process, the vibration assembly stops working, so that structures such as the second knocking plates 804 no longer vibrate and do not come into contact with the forging end face. Then, the second cleaning plate 806 and the second shoveling plate 803 extend out under the action of the telescopic structure and come into contact with the forging end face. Thus, during the rotation back process of the rotating rod 801, first, the second shoveling plate 803 shovels and cleans the scale on the forging end face, and then the brush hairs on the second cleaning plate 806 are used for further cleaning to complete the cleaning of the forging end face.

[0084] When the forging continues to move forward and the other end moves to the outer position of the end face cleaning mechanism, the second knocking plate 804, the second shoveling plate 803 and the second cleaning plate 806 on the other side of the rotating box 800 are used to perform cleaning in the same way.

[0085] Embodiment 4. The structure of this embodiment is basically the same as that of Embodiment 3, except that, as Figure 17 shown, the vibration assembly includes two fixing seats 810 symmetrically fixed to the inner side of the rotating box 800. A plurality of guiding cylinders 812 are symmetrically fixed to both sides of the fixing seats 810. A guiding shaft 811 is correspondingly fixed to the inner side surface of the second knocking plate 804. The guiding shaft 811 is slidably connected to the corresponding guiding cylinder 812, and the inner end is connected to the inner end of the guiding cylinder 812 through a spring. A plurality of worm wheels 814 are evenly arranged and rotatably connected between the two fixing seats 810. Cam 813 is symmetrically fixed on both sides of the worm wheel 814. A notch is provided on the side wall of the rotating box 800 corresponding to the position of the cam 813. A worm 815 is commonly engaged with one side of the plurality of worm wheels 814. One end of the worm 815 is connected to a motor.

[0086] When it is necessary to make the second knocking plate 804 work, the motor drives the worm 815, and through the transmission of the worm wheel 814 and the worm 815, the plurality of cams 813 rotate. During the rotation of the convex part of the cam 813, it contacts the second knocking plate 804 through the notch, and under the guiding and resetting action of the guiding shaft 811 and the spring, the second knocking plate 804 reciprocates to knock the scale on the end face of the forging.

[0087] Embodiment 5. The structure of this embodiment is basically the same as that of Embodiment 4, except that, as Figure 17 shown, the telescopic structure includes telescopic plates 808 located on both sides of the fixing seats 810. Third electromagnets 809 are provided at the relative positions of the telescopic plates 808 and the fixing seats 810. The third electromagnets 809 are electrically connected to a power supply and a switch. The other side of the telescopic plate 808 is connected to the inner side surface of the rotating box 800 through a spring. The inner end of the second shoveling plate 803 extends into the rotating box 800 and is fixed to the corresponding telescopic plate 808. A plurality of telescopic rods 807 are evenly fixed to the inner side surface of the second cleaning plate 806, and the inner ends of the plurality of telescopic rods 807 extend into the rotating box 800 and are fixedly connected to the corresponding telescopic plates 808.

[0088] When the second shoveling plate 803 and the second cleaning plate 806 are not needed, the third electromagnets 809 are energized to attract each other, causing the telescopic plates 808 to move inward. When the second shoveling plate 803 and the second cleaning plate 806 are needed, the third electromagnets 809 are powered off, and the telescopic plates 808 move outward under the action of the spring, thereby driving the second shoveling plate 803 and the second cleaning plate 806 to move outward so as to contact the end face of the forging and perform corresponding cleaning work.
