Description

Technical Field

[0001] The invention relates to the technical field of annealing furnaces, in particular to an annealing furnace for casting production. Background Art

[0002] Annealing furnace is a metal heat treatment process that slowly heats metal parts to a certain temperature in different annealing furnaces, keeps them warm for a period of time, and then cools them at an appropriate speed. After the castings enter the annealing furnace, oxide scale will appear on their surface, which will fall onto the heating device at the bottom of the annealing furnace. If these oxide scales are not handled in time, it is easy to cause a short circuit in the heating components, thereby causing damage to the heating components and making it impossible to continue heating normally.

[0003] In this regard, China's patent application number: CN202210152611.2 discloses an annealing furnace with a safety insurance mechanism, including an annealing furnace body, a fixed base welded at the lower end of the annealing furnace body, a receiving groove opened at the upper end of the fixed base, grooves symmetrically opened on the inner side of the receiving groove, sliding grooves equidistantly opened on the side of the receiving groove, a grid partition connected by bolts at the upper end of the fixed base, a heating device body is arranged in the receiving groove, slide plates are symmetrically welded on the left and right sides of the heating device body, and a fixed block is symmetrically welded on the lower end of the heating device body. The beneficial effect of the invention is that when it is necessary to clean the oxide scale of the workpiece in the receiving groove, the oxide scale and debris of the workpiece in the receiving groove are absorbed and cleaned by the dust suction pipe, and at the same time, the driving motor rotates, the driving motor drives the screw rod to rotate, the screw rod drives the movable nut to move, and the movable nut drives the dust suction pipe to slide along the receiving groove, so that the oxide scale and debris of the workpiece in the receiving groove can be cleaned.

[0004] The annealing furnace uses a reset mechanism and a shaking mechanism to shake off the oxide scale on the heating device body. However, since the heating device body is horizontally movable, for some oxide scales with a larger area, the reciprocating shaking will only drive them to move horizontally on the heating device body, but cannot shake them off the heating device body. Therefore, the oxide scales with a larger area will remain on the heating device body and need to be manually cleaned by maintenance personnel, which is inconvenient and will affect the normal operation of the annealing furnace.

[0005] Therefore, in order to solve the above problems, an annealing furnace for casting production is proposed. Summary of the invention

[0006] The object of the present invention is to provide an annealing furnace for casting production, so as to solve the problem that the annealing furnace in the prior art proposed in the above background technology cooperates with a resetting mechanism and a shaking mechanism to shake off the oxide scale on the heating device body, but since the heating device body is horizontally movable, for some oxide scales with larger areas, the reciprocating shaking will only drive them to move horizontally on the heating device body, but cannot shake them off from the heating device body. Therefore, the oxide scales with larger areas will remain on the heating device body, requiring maintenance personnel to manually clean them, which is inconvenient and will affect the normal operation and use of the annealing furnace.

[0007] To achieve the above object, the present invention provides the following technical solution: an annealing furnace for casting production, comprising: a fixed base, the top surface of which is mounted an annealing furnace body, a grid partition is fixedly mounted in the middle of the top surface of the fixed base, a fixed block is fixedly mounted on the inner wall of the fixed base, and a heating device body is mounted on the fixed block;

[0008] A movable door is installed on the front of the fixed base;

[0009] The driving mechanism that the cam is in the center is that the cam is provided with a toothed plate, and the toothed plate is provided with a toothed plate at the bottom.

[0010] Preferably, a pushing structure is installed on the lower side of the cleaning structure, and the pushing structure includes a threaded shaft, which is movably mounted on the inner wall of the fixed base through a bearing, and a driving motor is fixedly mounted on the rear wall of the fixed base. The middle part of the threaded shaft is threadedly connected with a threaded block, and the threaded shaft, the driving motor and the threaded block are respectively provided in two groups, and the bottom ends of the two groups of threaded blocks are respectively rotatably mounted with a right scraper and a left scraper, and the left end of the right scraper is movably mounted with a rotating connecting block through a rotating shaft, and a sliding groove is provided on the surface of the left scraper.

[0011] Preferably, the heating device body, the threaded rod and the threaded shaft are all installed in a front-to-back direction and are parallel to each other.

[0015] Preferably, the front end of the rotating connecting block is slidably mounted inside the sliding groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the annealing furnace of the present invention arranges elastic bristles and a pressure plate at the gap of the heating device body, and the elastic bristles can push upwards the oxide scale with a smaller area to tilt it, so that the oxide scale can fall downwards from the gap of the heating device body, and the pressure plate can crush the oxide scale with a larger area, so that the surface of the heating device body remains clean and tidy, thereby ensuring the user experience of the device.

[0017] A cleaning structure and a pushing structure are provided, and a driving motor is started, and the driving motor drives the threaded rod to rotate. The threaded rod is threadedly connected to the threaded sleeve. The rotation of the threaded rod drives the threaded sleeve and the rotating shaft to move from back to front in the fixed base. The rotating shaft moves relative to the rack plate, and the rotating gear is meshed with the rack plate. When the rotating shaft moves, the rotating gear rotates and rolls forward on the rack plate. When the rotating gear rotates, it drives the rotating shaft to rotate on the threaded sleeve, and the rotating shaft drives the pressure plate to rotate. When the rotating shaft moves, it drives the bracket to move forward through the connecting arm, and the bracket drives the heat insulation arc shield to move forward at the gap of the heating device body, so the pressure plate, the heat insulation arc shield and the rotating plate move forward together;

[0018] When the rotating shaft rotates, the rotating disk is driven to rotate through the first pulley, the transmission belt body and the second pulley. When the rotating disk rotates, the elastic bristles are driven to rotate. When the elastic bristles rotate, one end of the oxide skin with a smaller area accumulated on the top surface of the heating device body can be lifted up, so that the oxide skin is inclined, which is convenient for the oxide skin to fall downward through the gap of the heating device body to the bottom surface of the inner side of the fixed base. At the same time, the rotating disk and the elastic bristles will rotate at the gap of the heating device body, and the heat-insulating arc shielding plate will shield the rotating disk and the elastic bristles on both sides. The heat-insulating arc shielding plate is placed between the heating device body and the elastic bristles, which can prevent the elastic bristles from melting, bending and being damaged by contacting the high-temperature heating device body when rotating, thereby extending the service life of the elastic bristles and ensuring the pushing effect of the elastic bristles on the oxide skin.

[0019] As the pressure plate and the rotating plate continue to move forward, the pressure plate will contact the oxide scale with a larger area. When the pressure plate rotates, it can crush the oxide scale with a larger area and push it downward through the gap of the main body of the heating device to the bottom surface of the inner side of the fixed base, so that the surface of the main body of the heating device remains clean and tidy, ensuring the user experience of the device;

[0020] Start the driving motor, the driving motor drives the threaded shaft to rotate, the threaded shaft is threadedly connected with the threaded block, the rotation of the threaded shaft means that the threaded block moves forward in the fixed base, two groups of threaded blocks are provided, and the bottom ends are rotatably mounted inside the top surfaces of the right scraper and the left scraper respectively, and at the same time, the rotating connection block on the right scraper is slidably mounted in the sliding groove on the left scraper, so the movement of the two groups of threaded blocks can simultaneously drive the right scraper and the left scraper to move forward in the fixed base, and the movement of the right scraper and the left scraper pushes the oxide scale that falls on the inner bottom surface of the fixed base to move forward, so that the movable door can be opened to take it out;

[0021] When the front of the left scraper contacts the front side wall inside the fixed base, as the drive motor continues to run, the threaded shaft drives the threaded block to continue to move forward, and the right scraper and the left scraper rotate on the bottom of the threaded block, and the rotating connecting block will slide in the sliding groove, so that the right scraper and the left scraper remain horizontal, and the left scraper fits the front side wall inside the fixed base, which can improve the effect of pushing out the oxide scale, reduce the residue of oxide scale on the inside of the fixed base, and improve the user experience of the device.

A rack plate 26 is fixedly installed on the inner wall of the fixed base 1, and a pressure plate 27 is fixedly installed in the middle part of the rotating shaft 24. First pulleys 28 are installed on both sides of the pressure plate 27, and connecting arms 29 are movably installed on both ends of the rotating shaft 24 through bearings. The front end of the connecting arm 29 is fixedly connected to a bracket 210, and the top surface of the bracket 210 is fixedly connected to the bottom surface of the bracket 210.

Second pulleys 214 are fixedly installed on the left and right ends of the rotating disk 212, and a transmission belt body 215 is sleeved on the outer side of the second pulley 214. By arranging elastic bristles 213 and a pressure plate 27 at the gap of the heating device body 15, the elastic bristles 213 can push the oxide scale with a smaller area upward to tilt it, so that the oxide scale can fall downward from the gap of the heating device body 15, and for the oxide scale with a larger area, the pressure plate 27 can crush it, so that the surface of the heating device body 15 remains clean, ensuring the user experience of the device.

[0039] Furthermore, a pushing structure 3 is installed at the lower side of the cleaning structure 2, and the pushing structure 3 includes a threaded shaft 31, and the threaded shaft 31 is movably installed on the inner wall of the fixed base 1 through a bearing, and a driving motor 32 is fixedly installed on the rear wall of the fixed base 1. The middle part of the threaded shaft 31 is threadedly connected with a threaded block 33, and the threaded shaft 31, the driving motor 32 and the threaded block 33 are respectively provided with two groups, and the bottom ends of the two groups of threaded blocks 33 are rotatably installed with a right scraper 34 and a left scraper 36, respectively, and the left end of the right scraper 34 is movably installed with a rotating connecting block 35 through a rotating shaft, and a sliding groove 37 is provided on the surface of the left scraper 36. When the driving motor 32 is started, the driving motor 32 drives the screw The threaded shaft 31 rotates, and the threaded shaft 31 is threadedly connected to the threaded block 33. The rotation of the threaded shaft 31 means that the threaded block 33 moves forward in the fixed base 1. Two groups of threaded blocks 33 are provided, and the bottom ends are rotatably mounted inside the top surfaces of the right scraper 34 and the left scraper 36 respectively. At the same time, the rotating connecting block 35 on the right scraper 34 is slidably mounted in the sliding groove 37 on the left scraper 36. Therefore, the movement of the two groups of threaded blocks 33 can simultaneously drive the right scraper 34 and the left scraper 36 to move forward in the fixed base 1. The movement of the right scraper 34 and the left scraper 36 pushes the oxide scale dropped on the inner bottom surface of the fixed base 1 to move forward, making it easy to open the movable door 12 to remove it.

[0040] Furthermore, the heating device body 15, the threaded rod 21 and the threaded shaft 31 are all installed in the front-to-back direction and are parallel to each other. The threaded rod 21 and the threaded shaft 31 can respectively drive the pressure plate 27 and the right scraper 34 and the left scraper 36 to move forward and backward to realize the movement of the cleaning structure 2 and the pushing structure 3.

[0041] Furthermore, the output end of the driving motor 22 is fixedly connected to the threaded rod 21, the rotating shaft 24 is perpendicular to the heating device body 15, the rotating gear 25 is meshed with the rack plate 26, the pressure plate 27 and the rotating disk 212 are both located in the gap of the heating device body 15, and the rotating disk 212 is arranged at intervals. The driving motor 22 provides power for the rotation of the threaded rod 21. When the rotating shaft 24 moves, it can rotate by the meshing of the rotating gear 25 and the rack plate 26, and the pressure plate 27 and the rotating disk 212 can move in the gap of the heating device body 15.

[0042] Furthermore, the left and right ends of the bracket 210 are respectively sleeved on two groups of threaded rods 21, the heat-insulating arc-shaped shield plate 211 is located between the rotating disk 212 and the heating device body 15, and one end of the transmission belt body 215 is sleeved on the first pulley 28. The bracket 210 can move on the threaded rod 21 under the push of the connecting arm 29, and the heat-insulating arc-shaped shield plate 211 is placed between the heating device body 15 and the elastic bristles 213. It can prevent the elastic bristles 213 from melting, bending and being damaged by contacting the high-temperature heating device body 15 during rotation, and can extend the service life of the elastic bristles 213 and ensure the pushing effect of the elastic bristles 213 on the oxide scale. When the first pulley 28 rotates, the rotating disk 212 can be driven to rotate through the transmission belt body 215 and the second pulley 214.

[0043] Furthermore, the output end of the drive motor 32 is fixedly connected to the threaded shaft 31, the left end of the left scraper 36 and the right end of the right scraper 34 are respectively fitted with the left and right walls inside the fixed base 1, the bottom surfaces of the right scraper 34 and the left scraper 36 are both fitted with the bottom surface inside the fixed base 1, the right scraper 34 and the left scraper 36 are both installed at an angle, the drive motor 32 provides power for the rotation of the threaded shaft 31, the left scraper 36 and the right scraper 34 can move along the inner bottom surface and side wall of the fixed base 1, and can avoid missing oxide scale.

[0044] Furthermore, the front end of the rotating connecting block 35 is slidably installed inside the sliding groove 37, and the right scraper 34 and the left scraper 36 can be deflected at an angle so that the right scraper 34 and the left scraper 36 are parallel, which can ensure the pushing effect on the oxide scale.

[0045] Working principle: when it is necessary to clean the oxide scale of the casting at the gap of the heating device body 15, start the driving motor 22, the driving motor 22 drives the threaded rod 21 to rotate, the threaded rod 21 is threadedly connected with the threaded sleeve 23, the rotation of the threaded rod 21 drives the threaded sleeve 23 and the rotating shaft 24 to move from back to front in the fixed base 1, the rotating shaft 24 moves relative to the rack plate 26, the rotating gear 25 is meshed with the rack plate 26, when the rotating shaft 24 moves, the rotating gear 25 rotates and rolls forward on the rack plate 26, when the rotating gear 25 rotates, it drives the rotating shaft 24 to rotate on the threaded sleeve 23, the rotating shaft 24 drives the pressure plate 27 to rotate, when the rotating shaft 24 moves, it drives the bracket 210 to move forward through the connecting arm 29, the bracket 210 drives the heat insulation arc shield 211 to move forward at the gap of the heating device body 15, so the pressure plate 27, the heat insulation arc shield 211 and the rotating disk 212 move forward together;

[0046] When the rotating shaft 24 rotates, the rotating disk 212 is driven to rotate through the first pulley 28, the transmission belt body 215 and the second pulley 214. When the rotating disk 212 rotates, the elastic bristles 213 are driven to rotate. When the elastic bristles 213 rotate, one end of the oxide skin with a smaller area accumulated on the top surface of the heating device body 15 can be lifted up, so that the oxide skin is inclined, which is convenient for the oxide skin to fall downward through the gap of the heating device body 15 to the bottom surface of the inner side of the fixed base 1. At the same time, the rotating disk 212 and the elastic bristles 213 will rotate at the gap of the heating device body 15, and the heat insulation arc shielding plate 211 blocks the rotating disk 212 and the elastic bristles 213 on both sides. The heat insulation arc shielding plate 211 is placed between the heating device body 15 and the elastic bristles 213, which can prevent the elastic bristles 213 from melting, bending and being damaged by contacting the high-temperature heating device body 15 when rotating, and can extend the service life of the elastic bristles 213, and ensure the pushing effect of the elastic bristles 213 on the oxide skin;

[0047] Moreover, for some oxide scales with a larger area, the elastic bristles 213 cannot push them, or the pushing angle cannot make them fall downward from the gap of the heating device body 15. At this time, as the pressure plate 27 and the rotating plate 212 continue to move forward, the pressure plate 27 will contact the oxide scales with a larger area. When the pressure plate 27 rotates, it can crush the oxide scales with a larger area and push them downward through the gap of the heating device body 15 to fall onto the bottom surface of the inner side of the fixed base 1, so that the surface of the heating device body 15 remains clean and tidy, ensuring the user experience of the device.

[0048] At the same time, the driving motor 32 is started, and the driving motor 32 drives the threaded shaft 31 to rotate. The threaded shaft 31 is threadedly connected with the threaded block 33. The rotation of the threaded shaft 31 means that the threaded block 33 moves forward in the fixed base 1. The threaded block 33 is provided with two groups, and the bottom ends are rotatably mounted inside the top surfaces of the right scraper 34 and the left scraper 36 respectively. At the same time, the rotating connecting block 35 on the right scraper 34 is slidably mounted in the sliding groove 37 on the left scraper 36. Therefore, the movement of the two groups of threaded blocks 33 can simultaneously drive the right scraper 34 and the left scraper 36 to move forward in the fixed base 1. The movement of the right scraper 34 and the left scraper 36 pushes the oxide scale dropped on the inner bottom surface of the fixed base 1 to move forward, so that the movable door 12 can be opened to remove it.

[0049] When the front of the left scraper 36 contacts the front side wall of the inner side of the fixed base 1, as the drive motor 32 continues to run, the threaded shaft 31 drives the threaded block 33 to continue to move forward, and the right scraper 34 and the left scraper 36 rotate on the bottom surface of the threaded block 33, and the rotating connecting block 35 will slide in the sliding groove 37, so that the right scraper 34 and the left scraper 36 remain horizontal, and the left scraper 36 fits the front side wall of the inner side of the fixed base 1, which can improve the effect of pushing out the oxide scale, reduce the residual oxide scale on the inner side of the fixed base 1, and improve the user experience of the device.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
