Description

Technical Field

[0001] The invention relates to the technical field of forging processing, in particular 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 and deforming metal billets. They are divided into cold forging, warm forging and hot forging. Cold forging is generally processed at room temperature, while hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. During hot forging, more oxide scale will appear on the surface of the workpiece, part of which will fall off during the forging process, and some of the oxide scale will adhere to the forging, which needs to be cleaned.

[0003] The commonly used cleaning method is that the operator uses tools to clean manually, which is time-consuming and labor-intensive, and the effect is also poor. Patent publication number CN210358250U is a pipe forging oxide skin cleaning machine, which mainly includes a frame, a workbench, a motor, a gearbox and a transmission shaft, and the bottom of the transmission shaft is connected to a cylinder and a scraper mounting frame and a scraper; 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 cleaning machine can clean the circumferential surface of the forging, the position of the forging is fixed and there is no flipping structure, which makes it inconvenient to flip the pipe.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, please refer to the attached drawings, the present invention provides a technical solution: An automatic oxide scale cleaning device for improving the surface quality of shaft forgings, such as Figure 1 As shown, it includes a base 100, end plates 103 are symmetrically fixed at both ends of the top surface of the base 100, a moving mechanism 200 is provided between the two end plates 103, and a fixing frame 400 is provided in the middle of the top of the base 100; Two bosses 101 are symmetrically fixed on both sides of the top surface of the base 100. The two ends of the bosses 101 are located at the end plate 103, and a collecting groove 102 is provided between the two bosses 101. The two bottom ends of the fixing frame 400 are respectively fixed to the middle of the outer side surface of the bosses 101. like Figure 7 , 8 As shown, a plurality of lifting cylinders 403 are evenly arranged on the top of the fixing frame 400, and a lifting plate 404 is fixed to the bottom ends of the plurality of lifting cylinders 403. A knocking assembly 500, a shoveling assembly 600 and a cleaning assembly 700 are sequentially arranged on the bottom of the lifting plate 404 along the length direction of the base 100; like Figure 2As shown, a moving mechanism 200 is provided on the top of the boss 101, and a supporting rotating mechanism 300 is connected to the moving mechanism 200. The supporting rotating mechanism 300 includes an adjusting seat 204 connected to the moving mechanism 200, and two supporting boxes 304 and two supporting plates 303 are provided on the top of the adjusting seat 204, and a supporting shaft 302 is rotatably connected through the supporting plates 303 and the supporting boxes 304, and a plurality of supporting wheels 301 are evenly fixed on the supporting shaft 302, and a guide plate 205 inclined inwardly is fixed on the supporting plates 303 and the supporting boxes 304; A cavity is provided inside the adjustment seat 204, the bottom end of the support box 304 is connected to the adjustment seat 204, and a transmission assembly is provided in the adjustment seat 204, a rack 105 is provided between the two end plates 103, the rack 105 passes through the adjustment seat 204, and the support shaft 302 is correspondingly connected to the rack 105 through the transmission assembly.

[0023] When the forgings are transported, they are placed on two supporting rotating mechanisms 300 and on the supporting wheels 301 on both sides, wherein the positions of the supporting wheels 301 can be adjusted by moving the adjusting seat 204 so as to adjust the spacing between the supporting wheels 301 on both sides, thereby lifting the shaft forgings or lowering the position of the forgings, and adjusting the position of the shaft forgings to avoid the shaft forgings being too high or too low, 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 achieved by the lifting cylinder 403 and the lifting plate 404.

[0024] After the forging is in place, the adjusting seat 204 drives the supporting wheel 301 and the shaft forging to move toward the fixing frame 400 through the moving mechanism 200. While moving, the shaft forging and the supporting wheel 301 move relative to the rack 105, and then the supporting shaft 302 drives the supporting wheel 301 and the forging to rotate through the transmission assembly, so that when passing through the fixing frame 400, the circumferential surface of the shaft forging is knocked, the oxide scale is scraped off, and the surface of the forging is cleaned by the knocking assembly 500, the scraping assembly 600 and the cleaning assembly 700 in turn, thereby improving the surface cleaning effect of the forging.

[0025] The present invention uses the moving mechanism 200 to make the supporting rotating mechanism 300 and the forging move synchronously, and during the movement, the forging is driven to rotate by the rotation of the transmission assembly and the supporting wheel 301, so that the surface of the forging is cleaned more comprehensively, and the movement of the forging is consistent with the supporting wheel 301, thereby reducing damage to the supporting wheel 301 and other structures; The present invention uses a knocking component 500 to knock the oxide scale on the surface of the shaft forging, so that the oxide scale becomes loose or even easy to fall off relative to the shaft forging, making subsequent cleaning faster and more convenient. The scraping component 600 is used to scrape and clean the oxide scale remaining after the knocking, making the oxide scale cleaning more thorough. After the oxide scale cleaning is completed, the cleaning component 700 is used to further clean the fine debris and dust adhering to the end surface, thereby improving the surface quality of the forging.

[0026] The present invention can adjust the position of the support wheel 301 and the height position of the structures such as the knocking assembly 500, so as to improve the application range of the equipment. During the cleaning process, the cleaned materials are guided and discharged through the guide plate 205 and fall into the collecting trough 102, which is convenient for subsequent recycling and processing.

[0027] Among them, Figure 2 , 3 As 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, both 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 to a transmission pulley 206, the two transmission pulleys 206 are connected by a transmission belt, and one end of one of the screw rods 202 is connected to a motor, a plurality of adjusting hydraulic cylinders 203 are evenly arranged on the inner side of the moving seat 201, and the outer side surface of the adjusting seat 204 is correspondingly connected to the plurality of adjusting hydraulic cylinders 203.

[0028] When the shaft forgings need to be moved, the two screws 202 are rotated simultaneously through the drive of the motor and the transmission pulley 206, so that the moving seats 201 on both sides move simultaneously, and drive the adjustment seat 204 and the support wheel 301 and other structures to move, so as to move the shaft forgings, so as to realize the transportation of the shaft forgings; the position of the adjustment seat 204 and the support wheel 301 can be adjusted by adjusting the hydraulic cylinder 203, so as to adjust the position of the shaft forgings.

[0029] Among them, Figure 5 As shown, the transmission assembly includes two first pulleys 305 fixed on the support shaft 302, and the two first pulleys 305 are respectively located inside the two support boxes 304, and the lower part of the first pulley 305 is connected to a second pulley 306 through a transmission belt, and the second pulley 306 is rotatably connected to the inner cavity of the adjustment seat 204, and is coaxially fixed with a first bevel gear 307, as shown in FIG. Figure 6 As shown, a second bevel gear 308 is meshed on one side of the first bevel gear 307, the second bevel gear 308 is rotatably connected to the inner wall of the adjustment seat 204, and a moving gear 309 is coaxially fixed to the bottom, and the moving gear 309 is meshed with the rack 105; like Figure 4As shown, a sliding groove 104 is fixed on the inner side of the end plate 103 at a position corresponding to the rack 105, and the end of the rack 105 is slidably connected in the sliding groove 104, and one side of the sliding end is connected to one end of the sliding groove 104 through a spring, so that when the adjustment seat 204 moves, the rack 105 can adjust its position accordingly and remain engaged with the moving gear 309.

[0030] When the adjustment seat 204 and the support wheel 301 and other structures move, the moving gear 309 moves relative to the rack 105, thereby causing the moving gear 309 to rotate, and through the transmission of the first bevel gear 307 and the second bevel gear 308, the first pulley 305 and the second pulley 306, the support shaft 302 drives the support wheel 301 to rotate, so that during the movement, the shaft forgings are driven to rotate so as to clean the oxide scale of the shaft forgings; in order to ensure that the rotation directions of the support wheels 301 on both sides are the same, the front and rear positions of the first bevel gear 307 and other structures in the two support rotating mechanisms 300 relative to the second pulley 306 can be adjusted.

[0031] Among them, Fig. 9 As shown, the knocking assembly 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. Fig.10 As 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; like Fig.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.

[0032] 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.

[0033] Among them, Fig. 9 As shown, the shovel assembly 600 includes a first shovel plate 601 located in the middle below the lifting plate 404. Fig.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. Fig.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.

[0034] When the shaft forging is about to move to the bottom of the first shovel plate 601, the first electromagnet 603 repels each other with the same charges, causing the movable plate 602 to stretch the spring and drive the first shovel plate 601 to move upward, so as to leave a certain distance so that the shaft forging can move smoothly to the bottom of the first shovel plate 601. Then the first electromagnet 603 is powered off, and the movable plate 602, under the action of the spring, drives the first shovel plate 601 to move downward and contact the top of the shaft forging, so as to remove and clean the oxide scale on the surface of the shaft forging during its movement and rotation.

[0035] Among them, Fig. 9 As shown, the cleaning assembly 700 includes a first cleaning plate 701 located below the lifting plate 404. Both sides of the first cleaning plate 701 are symmetrically inclined, and cleaning bristles 702 are evenly distributed on both sides of the bottom. Fig.14As shown, vertical second spring frames 704 are symmetrically fixed on both sides of the top of the first cleaning plate 701, the top of the second spring frame 704 passes through the lifting plate 404, and is fixed with a horizontal second spring plate 705, the top of the second spring plate 705 is connected to the top of the fixing frame 400 through a spring, and the bottom of the second spring plate 705 and the corresponding position on the lifting plate 404 are provided with a second electromagnet 706, and the second electromagnet 706 is electrically connected to a power supply and a switch.

[0036] When the shaft forging approaches the cleaning assembly 700, the second electromagnet 706 is energized to repel each other, causing the second spring plate 705 to compress the spring and drive the second spring frame 704 and the first cleaning plate 701 to move upward, so that the shaft forging can move smoothly to the bottom of the first cleaning plate 701, and then the second electromagnet 706 is de-energized, 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 that the forging is further cleaned during the movement and rotation of the shaft forging, thereby improving the cleaning effect on the surface of the forging.

[0037] Embodiment 2: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 7 As shown, a pump body 401 is provided on the fixing frame 400, and a water inlet pipe 402 is provided on one side of the pump body 401. The water inlet pipe 402 is arranged along the outer side of the fixing frame 400, and the bottom end thereof passes through one of the bosses 101 and extends into the collecting tank 102. A water outlet pipe 406 is provided at the bottom of the pump body 401. Fig.15 As shown, a water spray pipe 707 is provided on the top of the first cleaning plate 701, and a water outlet pipe 406 is connected to the water spray pipe 707, and the water outlet pipe 406 is set as a telescopic tube or a long hose so as to cooperate with the movement of the first cleaning plate 701, and a plurality of nozzles 703 are evenly arranged on the bottom of the water spray pipe 707, and the nozzle 703 passes through the middle position of the first cleaning plate 701, and water is filled in the aggregate trough 102, and water enters the water spray pipe 707 through the water outlet pipe 406 through the pump body 401 and the water inlet pipe 402, and is sprayed out through the nozzle 703, so that while the cleaning brush 702 is cleaning, the forgings can be sprayed and cooled by water, thereby improving the cleaning effect.

[0038] Embodiment 3: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 7 As shown, an end surface cleaning mechanism is provided on one side of the fixing frame 400, and the end surface cleaning mechanism is located at the outer side of the cleaning assembly 700. The end surface cleaning mechanism includes a mounting plate 405 fixed to the middle of the top of the fixing frame 400, and a central shaft 802 is rotatably connected to the middle of the bottom of the mounting plate 405. The inner side end of the central shaft 802 is connected to a motor, and a rotating rod 801 is fixed to the outer side end. A rotating box 800 is fixed to the bottom end of the rotating rod 801, as shown in FIG. Fig.16As shown, a second knocking plate 804 is provided in the middle of both sides of the rotating box 800, a second knocking seat 805 is fixed on the outer surface of the second knocking plate 804, and a vibration assembly is provided between the two second knocking plates 804, a second shovel 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, and the second shovel plate 803 and the second cleaning plate 806 are connected to the rotating box 800 through a telescopic structure, and bristles are evenly distributed on the outer surface of the second cleaning plate 806.

[0039] 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, and during the rotation, the second knocking plate 804 and the second knocking seat 805 are vibrated by the vibration component and contact the end face of the forging so as to perform the knocking treatment, and during the knocking treatment, the second shovel plate 803 and the second cleaning plate 806 do not contact the end face of the shaft forging; When the tapping process is completed, the rotating rod 801 and the rotating box 800 rotate. During the rotation, the vibration component stops working, so that the second knocking plate 804 and other structures no longer vibrate and do not contact the end face of the forging. Then the second cleaning plate 806 and the second scraping plate 803 extend outward under the action of the telescopic structure and contact the end face of the forging. Therefore, during the rotation of the rotating rod 801, the oxide scale on the end face of the forging is first scraped off and cleaned by the second scraping plate 803, and then further cleaned by the bristles on the second cleaning plate 806 to complete the cleaning of the end face of the forging.

[0040] When the forging continues to move forward and the other end moves to the outer side of the end surface cleaning mechanism, the second knocking plate 804, the second shovel plate 803 and the second cleaning plate 806 on the other side of the rotating box 800 are cleaned in the same manner.

[0041] Embodiment 4: The structure of this embodiment is basically the same as that of embodiment 3, except that Fig.17 As shown, the vibration assembly includes two fixed seats 810 symmetrically fixed on the inner side of the rotating box 800, and multiple guide cylinders 812 are symmetrically fixed on both sides of the fixed seats 810. A guide shaft 811 is correspondingly fixed on the inner side surface of the second knocking plate 804. The guide shaft 811 is slidably connected to the corresponding guide cylinder 812, and the inner end is connected to the inner end of the guide cylinder 812 through a spring. Multiple worm gears 814 are evenly arranged and rotatably connected between the two fixed seats 810, and cams 813 are symmetrically fixed on both sides of the worm gear 814. A groove is provided on the side wall of the rotating box 800 at the position corresponding to the cam 813. One side of the multiple worm gears 814 is commonly meshed with a worm 815, and one end of the worm 815 is connected to a motor.

[0042] When the second knocking plate 804 needs to be operated, the worm 815 is driven by a motor, and the multiple cams 813 are rotated through the transmission of the worm wheel 814 and the worm 815. During the rotation, the raised part of the cam 813 contacts the second knocking plate 804 through the groove, and under the guiding and resetting action of the guide shaft 811 and the spring, the second knocking plate 804 moves back and forth to knock the oxide scale on the end face of the forging.

[0043] Embodiment 5: The structure of this embodiment is basically the same as that of embodiment 4, except that Fig.17 As shown, the telescopic structure includes a telescopic plate 808 located on both sides of the fixed seat 810, and a third electromagnet 809 is provided at the relative position of the telescopic plate 808 and the fixed seat 810. The third electromagnet 809 is 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, and the inner end of the second shovel plate 803 extends into the rotating box 800 and is fixed to the telescopic plate 808 on the corresponding side. A plurality of telescopic rods 807 are evenly fixed on 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 telescopic plate 808 on the corresponding side.

[0044] When the second shovel plate 803 and the second cleaning plate 806 are not needed, the third electromagnet 809 is energized to attract each other, causing the telescopic plate 808 to move inward. When the second shovel plate 803 and the second cleaning plate 806 are needed, the third electromagnet 809 is de-energized, and the telescopic plate 808 moves outward under the action of the spring, thereby driving the second shovel 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.
