Description

Technical Field

[0001] The invention relates to the technical field of cleaning structures, in particular to an auxiliary peeling and cleaning structure for processing metal rings by a ring rolling machine. Background Art

[0002] Metal rings are core basic components in the fields of mechanical transmission, bearings, aerospace, etc., and their manufacturing quality directly affects the performance and service life of the equipment. In the processing of metal rings, the ring rolling machine is an important plastic forming equipment, which gradually forms the metal blank into a ring through radial rolling and axial rolling. However, during the hot rolling forming process, the metal material undergoes a violent oxidation reaction with oxygen in a high temperature environment, and a dense oxide scale layer will inevitably form on the surface. This oxide scale is mainly composed of metal oxides such as iron oxide, and its thickness varies with process parameters such as heating temperature and rolling time, usually ranging from tens to hundreds of microns.

[0003] During the rolling process of the metal ring, the oxide scale on its surface will break, but will not fall off completely, and workers need to remove it by cleaning. However, since the temperature of the metal ring is high during processing, manual peeling is more dangerous. In addition, since the oxide scale has an unfixed warping direction when it breaks, workers need to clean and peel it from different directions, which makes the peeling work more cumbersome and difficult to operate. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a ring rolling machine processing metal ring auxiliary peeling cleaning structure, the specific technical solution adopted is: The invention discloses an auxiliary peeling and cleaning structure for processing a metal ring by a ring rolling machine, comprising two relatively distributed air blowing units, wherein the air blowing units are sleeved on the metal ring; The air blowing unit includes a rotating ring and a guide unit, and the rotating ring is provided with a plurality of support columns distributed circumferentially. The support columns rotate on the rotating ring, and the rotation axis of the support columns is perpendicular to the axis of the rotating ring. Each of the support columns is provided with a fixed arm, and a nozzle is provided at one end of the fixed arm. The other end of the fixed arm is connected to the guide unit, and the guide unit is used to adjust the angle between the fixed arm and the nozzle.

[0005] Furthermore, the guide unit includes a guide ring, a guide groove is opened on the end face of the guide ring, and the guide groove consists of a first arc groove, two second arc grooves and a third arc groove. The first arc groove is used to make the direction of the nozzle match the outer wall of the metal ring, the second arc groove is used to make the direction of the nozzle match the upper and lower planes of the metal ring, and the third arc groove is used to make the direction of the nozzle match the inner wall of the metal ring.

[0006] Further, the opening shape of the nozzle is wavy.

[0007] Further, the fixed arm passes through the support column and slides relative thereto. A plurality of sliding columns are slidably arranged in the guiding groove. Fixing platforms are arranged on each of the sliding columns, and the fixing platforms are rotatably connected to the corresponding fixed arms. Wherein, an elastic body is used to connect the support column and the fixed arm thereon.

[0008] Further, the air-blowing unit further includes a conveying unit for conveying gas to the nozzle. The conveying unit includes an annular chamber composed of an outer circular groove and an inner shielding ring. The inner shielding ring rotates on the outer circular groove, and the rotating ring is connected to the inner shielding ring. The outer circular groove is connected to an external gas path. Wherein, the nozzle is connected to the inner shielding ring through a pipeline, and the nozzle is communicated with the annular chamber through the pipeline.

[0009] Further, the rotating ring, the guiding ring, the outer circular groove and the inner shielding ring are all composed of two parts, and each part of the rotating ring is fixedly connected to the corresponding part of the inner shielding ring.

[0010] Further, at least one set of power sources are arranged on each part of the outer circular groove, and the power sources are used to provide power for the corresponding parts of the inner shielding ring.

[0011] Further, the cleaning unit further includes a housing and an adjusting unit. The housing is composed of two buckles arranged up and down. Each part of the guiding ring and each part of the outer circular groove are installed in the corresponding buckle. A discharge hopper for discharging debris is arranged at the bottom of the lower buckle. The adjusting unit includes a back plate and two moving platforms slidably mounted on the back plate. The two moving platforms are respectively fixedly connected to the two buckles. A driving disc is rotatably arranged on the back plate, and the driving disc is rotatably connected to the two moving platforms through eccentric push-pull arms.

[0012] The beneficial effects of the present invention are as follows: By adopting the method of allowing air flow to drill into the gap between the oxide skin and the surface of the metal ring, the air flow can support and break the outer skin, thereby realizing the skin removal work. Moreover, by using air flows in two opposite directions, the skin removal work for the skin warping in any direction can be realized. Since the air flow needs to perform skin removal treatment on different positions such as the outer ring, inner ring, upper and lower surfaces of the metal ring, the tilt angle of the nozzle can be adjusted, so as to ensure that the air flow drills into the gap at the optimal angle and improve the outer supporting force of the air flow on the skin. Compared with the traditional manual cleaning and skin removal operation, this skin removal method can save a large amount of manpower and improve safety. Description of the Drawings

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] As Figures 1 to 7 shown, an auxiliary debarking and cleaning structure for machining a metal ring by a ring rolling machine according to the present invention includes two air-blowing units 1 distributed oppositely, and the air-blowing unit 1 is sleeved on the metal ring 23; The air-blowing unit 1 includes a rotating ring 2 and a guiding unit. A plurality of support columns 3 are circumferentially distributed on the rotating ring 2. The support columns 3 rotate on the rotating ring 2, and the rotation axis of the support columns 3 is perpendicular to the axis of the rotating ring 2. A fixed arm 4 is provided on each support column 3. One end of the fixed arm 4 is provided with a nozzle 5, and the other end of the fixed arm 4 is connected to the guiding unit, and the guiding unit is used to adjust the angles of the fixed arm 4 and the nozzle 5; In the present invention, the two air-blowing units 1 are distributed oppositely, so the directions of the air discharged from the plurality of nozzles 5 on the two air-blowing units 1 are opposite; the rotating ring 2 is used to provide an installation position for the plurality of support columns 3, and when the rotating ring 2 rotates, it can drive the plurality of support columns 3 to rotate synchronously, so that the nozzles 5 on each support column 3 can perform circular motion, and the nozzles 5 can perform circular motion around a part of the metal ring 23, so as to clean the circumferential outer wall, upper and lower surfaces and circumferential inner wall of the metal ring 23, and cooperate with the circular motion of the metal ring 23 during ring rolling, so as to perform a comprehensive debarking treatment on the surface of the metal ring 23; the support columns 3 are rotatably installed on the rotating ring 2. Specifically, a through fixing groove can be opened on the inner wall or the side wall of the rotating ring 2, and the support columns 3 are rotatably installed in the fixing groove. Since the support columns 3 can rotate, the inclination angle of the nozzles 5 can be adjusted; since the rotation axis of the support columns 3 is perpendicular to the axis of the rotating ring 2, the plane where the adjustment trajectory of the nozzles 5 is located can coincide with the axis of the rotating ring 2, so that the movement trajectory of the nozzles 5 can be limited; the guiding unit is mainly used to guide and adjust the inclination angle of the nozzles 5; It should be noted that since the circumferential outer wall of the metal ring 23 is convex, the upper and lower surfaces of the metal ring 23 are flat, and the circumferential inner wall of the metal ring 23 is concave, when the nozzles 5 rotate with the rotating ring 2, their inclination directions need to change to adapt to their different working positions; When in use, the metal ring 23 passes through the two rotating rings 2 and is rotated. Each rotating ring 2 rotates on itself, and the rotating ring 2 drives several supporting columns 3 thereon to move synchronously, so that the nozzle 5 rotates around a part of the metal ring 23. The nozzle 5 can move to different surfaces on the metal ring 23, and the high-speed airflow discharged by the nozzle 5 can be used for air-blowing and cleaning of the oxide skin on the surface of the metal ring 23; because the airflow can drill into the gap between the oxide skin and the surface of the metal ring 23, the external support force of the airflow in the gap is used to break and fall off the skin layer, thereby achieving the effect of peeling; because the directions of the warping of the skin layer are different, two air-blowing units 1 need to be configured to clean the skin layer from two directions, and in other directions, because as long as the skin layer is warped, there will be an open gap in the direction of air flow, so air can be allowed to drill into the gap, so that the warping phenomenon of the skin layer in any direction can be peeled by airflow in two directions; By using the method of airflow drilling into the gap between the oxide scale and the surface of the metal ring 23, the airflow breaks the outer support of the cortex, thereby achieving peeling, and by utilizing the airflow in two relative directions, the peeling of the cortex that is tilted in any direction can be achieved; because the airflow needs to peel the outer ring, inner ring, upper and lower surfaces of the metal ring 23 and other different positions, the inclination angle of the nozzle 5 can be adjusted, which can ensure that the airflow drills into the gap at the best angle, thereby increasing the outer support force of the airflow on the cortex; compared with the traditional manual cleaning and peeling operation, this peeling method can save a lot of manpower and improve safety.

[0020] Further, the guide unit includes a guide ring 6, and a guide groove is opened on the end surface of the guide ring 6, and the guide groove is composed of a first arc groove 7, two second arc grooves 8 and a third arc groove 9. The first arc groove 7 is used to make the direction of the nozzle 5 match the outer wall of the metal ring 23, the second arc groove 8 is used to make the direction of the nozzle 5 match the upper and lower planes of the metal ring 23, and the third arc groove 9 is used to make the direction of the nozzle 5 match the inner wall of the metal ring 23; In the present invention, Figure 6As shown, since the first arc groove 7, the second arc groove 8 and the third arc groove 9 on the guide ring 6 can guide the fixed arm 4 in different directions, the data such as the curvature, the center position and the like of the first arc groove 7, the second arc groove 8 and the third arc groove 9 are different, and the guide ring 6 can be regarded as composed of parts with different curvatures; since the rotation axis of the support column 3 is perpendicular to the axis of the rotating ring 2, the support column 3 can be used to limit the sliding of the end of the fixed arm 4 in the guide groove, so that the fixed arm 4 cannot move at will; when the end of the fixed arm 4 moves in the first arc groove 7, the nozzle 5 corresponds to the position of the outer wall of the circumference of the metal ring 23. Since the oxide scale on the metal ring 23 at this position is convex, the airflow discharged from the nozzle 5 can flow in the horizontal direction. When the end of the fixed arm 4 is at the first arc groove 7, the nozzle 5 corresponds to the outer wall of the circumference of the metal ring 23. When moving in the second arc groove 8, the nozzle 5 corresponds to the upper and lower surfaces of the metal ring 23. Since the upper and lower surfaces of the metal ring 23 are both planes, the nozzle 5 needs to have a certain inclination angle toward the surface of the metal ring 23. The inclination angle is small, and the air discharged from the nozzle 5 only needs to be blown onto the metal ring 23 to allow the airflow to drill into the gap at the corresponding position. When the end of the fixed arm 4 moves in the third arc groove 9, the nozzle 5 corresponds to the inner wall of the circumference of the metal ring 23. Since the metal ring 23 is concave at this position, the oxide scale is relatively hidden, and the inclination angle of the nozzle 5 needs to be further increased to facilitate blowing the airflow onto the inner wall of the metal ring 23. Therefore, using the above method, the inclination angle of the nozzle 5 can be adjusted in a targeted manner to facilitate the nozzle 5 to effectively clean the oxide scale at different positions on the surface of the metal ring 23.

[0021] Further, the opening shape of the nozzle 5 is wavy; By setting the opening of the nozzle 5 to be wavy, the airflow discharged from the nozzle 5 can contact different positions of the metal ring 23 within a small range in the circumferential direction of the metal ring 23, that is, the airflow discharged from the nozzle 5 diffuses outward in a wave shape, thereby achieving the effect of using the airflow to clean the surface of the metal ring 23, and the number of waves is the number of cleaning times, which effectively improves the peeling effect.

[0022] Furthermore, the fixed arm 4 passes through the support column 3 and slides relatively, and a plurality of sliding columns 11 are slidably arranged in the guide groove, and a fixing platform 10 is arranged on each sliding column 11, and the fixing platform 10 is rotatably connected with the corresponding fixed arm 4; The support column 3 and the upper fixed arm 4 are connected via an elastic body 12; Since different positions on the guiding ring 6 have different guiding effects on the nozzle 5, the distances between the support columns 3 and the guiding ring 6 are not equal on any plane where the axis of the rotating ring 2 lies. That is, when the support columns 3 and the nozzle 5 perform circular motion following the rotating ring 2, the fixed arm 4 needs to slide on the support columns 3 to ensure that the guiding ring 6 always has a guiding effect on the nozzle 5. To achieve the above purpose, the elastic body 12 can be used to provide elastic force for the fixed arm 4, so that the sliding column 11 at the end of the fixed arm 4 is always located in the guiding groove on the guiding ring 6, thus ensuring the normal operation of the equipment. The fixed platform 10 is mainly used to connect the sliding column 11 and the fixed arm 4. And since the support column 3 can rotate on the rotating ring 2, the fixed arm 4 needs to be rotatably connected to the sliding column 11.

[0023] Further, the air-blowing unit 1 further includes a conveying unit for conveying gas to the nozzle 5; The conveying unit includes an annular chamber composed of an outer circular groove 13 and an inner shielding ring 14. The inner shielding ring 14 rotates on the outer circular groove 13, and the rotating ring 2 is connected to the inner shielding ring 14, and the outer circular groove 13 is connected to an external gas path; Wherein, the nozzle 5 is connected to the inner shielding ring 14 through a pipeline, and the nozzle 5 is communicated with the annular chamber through the pipeline; Since the rotating ring 2 needs to drive a plurality of nozzles 5 to perform circular motion, and the nozzles 5 need to continuously exhaust gas outward, a special conveying unit needs to be provided for the nozzles 5 to meet the motion requirements of the nozzles 5. Here, the annular chamber and the pipeline composed of the outer circular groove 13 and the inner shielding ring 14 can be used to supply gas to the nozzle 5. When the nozzle 5 rotates, the inner shielding ring 14 will move synchronously, thus ensuring the continuous and normal supply of gas. To simplify the motion mode, the rotating ring 2 is directly connected to the inner shielding ring 14, so that the movement of the inner shielding ring 14 can drive the rotating ring 2 and the structures thereon to move synchronously.

[0024] Further, the rotating ring 2, the guiding ring 6, the outer circular groove 13 and the inner shielding ring 14 are all composed of two parts, and each part of the rotating ring 2 is fixedly connected to the corresponding part of the inner shielding ring 14; Since the metal ring 23 needs to pass through the air-blowing unit 1 to perform circular motion, to meet the normal assembly requirements of the metal ring 23 and the air-blowing unit 1, the rotating ring 2, the guiding ring 6, the outer circular groove 13 and the inner shielding ring 14 need to be set in a structural form composed of two parts, that is, the air-blowing unit 1 is separated into an upper and a lower part. When the air-blowing unit 1 needs to be assembled to the outside of the metal ring 23, the two parts of the air-blowing unit 1 approach each other and are butt-jointed and combined. When the metal ring 23 is removed, the two parts of the air-blowing unit 1 can be separated from each other.

[0025] Further, at least one set of power sources is provided on each part of the outer circular groove 13, and the power sources are used to provide power for the corresponding parts of the inner shielding ring 14; Since the air injection unit 1 is divided into upper and lower parts, in order to ensure the normal operation of the rotating ring 2 and prevent a part of the inner shielding ring 14 from separating from a part of the corresponding outer circular groove 13, at least one set of power sources needs to be provided on each part of the outer circular groove 13. In this way, the power sources provide a positioning function for the inner shielding ring 14, ensuring that in the natural state, a part of the inner shielding ring 14 can be stably on a part of the corresponding power motor 15, and multiple sets of power sources can continuously provide power for the rotation of the rotating ring 2 and the inner shielding ring 14. The power sources can be composed of transmission wheels 16 installed on each part of the outer circular groove 13 and retaining covers 17 installed at the output ends of the transmission wheels 16. The retaining covers 17 are in transmission connection with the corresponding parts of the inner shielding ring 14.

[0026] Furthermore, the cleaning unit further includes a housing and an adjustment unit. The housing is composed of two retaining covers 17 distributed up and down. Each part of the guiding ring 6 and each part of the outer circular groove 13 are installed in the corresponding retaining cover 17. A discharge hopper 18 for discharging debris is provided at the bottom of the lower retaining cover 17. The adjustment unit includes a back plate 19 and two moving platforms 20 slidably installed on the back plate 19. The two moving platforms 20 are respectively fixedly connected to the two retaining covers 17. A driving disk 21 is rotatably provided on the back plate 19. The driving disk 21 is rotatably connected to the two moving platforms 20 through eccentric push-pull arms 22. The housing composed of two retaining covers 17 can provide installation positions for the two parts of each air injection unit 1. The guiding ring 6 and the outer circular groove 13 are both fixed in the corresponding retaining cover 17. When the two retaining covers 17 separate or approach each other, the two parts of the air injection unit 1 separate or approach each other. The discharge hopper 18 installed at the bottom of the housing can be used to provide a discharge channel for the peeled scale debris, thus preventing the scale from depositing in the housing and affecting the normal operation of its internal structure. The back plate 19 and the two moving platforms 20 can support the two retaining covers 17. The back plate 19 can be installed on an external ring rolling machine. The driving disk 21 can drive the two moving platforms 20 and the two retaining covers 17 to move synchronously relative to each other through the two push-pull arms 22, so as to position the midpoint between the two retaining covers 17. The rotation of the driving disk 21 can be powered by an external driving motor.

[0027] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
