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 on a ring rolling machine. Background Art

[0002] Metal rings are core components in mechanical transmission, bearings, aerospace, and other fields, 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 and axial rolling. However, during the hot rolling process, the metal material undergoes a violent oxidation reaction with oxygen in a high-temperature environment, and a dense oxide scale layer is inevitably formed 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, and usually ranges 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. Workers need to remove it by cleaning or other means. 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 and cleaning structure, the specific technical solution adopted is:

[0005] The present invention provides an auxiliary peeling and cleaning structure for processing metal rings on a ring rolling machine, comprising two air blowing units that are relatively distributed and are sleeved on the metal ring;

[0006] The air blowing unit includes a rotating ring and a guide unit, and several support columns are distributed circumferentially of the rotating ring. 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.

[0007] Furthermore, the guide unit includes a guide ring, and a guide groove is provided on the end face of the guide ring. The guide groove consists of a first arc groove, two second arc grooves and a third arc groove. When 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.

[0008] Furthermore, the opening shape of the nozzle is wavy.

[0009] Furthermore, the fixed arm passes through the support column and slides relatively, a plurality of sliding columns are slidably arranged in the guide groove, and a fixing platform is provided on each of the sliding columns, and the fixing platform is rotatably connected to the corresponding fixed arm;

[0010] Wherein, the support column and the fixed arm thereon are connected via an elastic body.

[0011] Furthermore, the air blowing unit further comprises a delivery unit for delivering gas to the nozzle;

[0013] The nozzle is connected to the inner shielding ring through a pipeline, and the nozzle is communicated with the annular chamber through the pipeline.

[0014] Furthermore, the rotating ring, the guide 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 each corresponding part of the inner shielding ring.

A driving disk is rotatably arranged on the back plate. The driving disk and the two movable platforms are rotatably connected through an eccentrically arranged push-pull arm.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0033] like Figures 1 to 7 As shown, the present invention provides an auxiliary peeling and cleaning structure for metal rings processed by a ring rolling machine, comprising two relatively distributed air blowing units 1, the air blowing units 1 being sleeved on the metal ring 23;

[0034] The air blowing unit 1 includes a rotating ring 2 and a guide unit. There are several support columns 3 distributed circumferentially around 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. Each support column 3 is provided with a fixed arm 4, one end of which is provided with a nozzle 5. The other end of the fixed arm 4 is connected to the guide unit, and the guide unit is used to adjust the angle between the fixed arm 4 and the nozzle 5.

[0035] In the present invention, the two air blowing units 1 are relatively distributed, so the directions in which the air is discharged by the several nozzles 5 on the two air blowing units 1 are opposite; the rotating ring 2 is used to provide a mounting position for the several support columns 3, and when the rotating ring 2 rotates, it can drive the several support columns 3 to rotate synchronously, so that the nozzles 5 on each support column 3 can perform a circular motion, and the nozzles 5 can perform a circular motion around a part of the metal ring 23, thereby cleaning the outer wall, upper and lower surfaces and inner wall of the circumference of the metal ring 23, and cooperating with the circular motion of the metal ring 23 when rolling the ring, thereby cleaning the surface of the metal ring 23 Perform a comprehensive peeling process; the support column 3 is rotatably installed on the rotating ring 2. Specifically, a penetrating fixed groove can be opened on the inner wall of the rotating ring 2 or the side wall of the rotating ring 2, and the support column 3 can be rotatably installed in the fixed groove. Since the support column 3 can rotate, the inclination angle of the nozzle 5 can be adjusted; since the rotation axis of the support column 3 is perpendicular to the axis of the rotating ring 2, the surface where the adjustment trajectory of the nozzle 5 is located can coincide with the axis of the rotating ring 2, so that the movement trajectory of the nozzle 5 can be limited; the guide unit is mainly used to guide and adjust the inclination angle of the nozzle 5;

[0036] It should be noted that, since the outer circumferential wall of the metal ring 23 is convex, the upper and lower surfaces of the metal ring 23 are flat, and the inner circumferential wall of the metal ring 23 is concave, the tilt direction of the nozzle 5 needs to change when it rotates with the rotating ring 2 to adapt to its different working positions.

[0037] When in use, the metal ring 23 passes through the two rotating rings 2 and rotates, and each rotating ring 2 rotates, and the rotating ring 2 drives several supporting columns 3 on it to move synchronously, so that the nozzle 5 rotates around a part of the metal ring 23, and the nozzle 5 can move to different surfaces on the metal ring 23. The high-speed airflow discharged by the nozzle 5 can be used to blow and clean the oxide scale on the surface of the metal ring 23; because the airflow can drill into the gap between the oxide scale 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, thereby achieving the effect of peeling; because the directions of the cortex warping are different, two air blowing units 1 are required to clean the cortex from two directions, and in other directions, as long as the cortex warps, there will be an open gap in the direction of air flow, so that air can be allowed to drill into the gap, so that the warping phenomenon of the cortex in any direction can be peeled by airflow in two directions;

[0038] By using the air flow to drill into the gap between the oxide scale and the surface of the metal ring 23, the air flow breaks the outer support of the cortex, thereby achieving peeling, and by utilizing the air flow in two relative directions, the peeling of the cortex that is tilted in any direction can be achieved; since the air flow needs to peel different positions of the metal ring 23, such as the outer ring, inner ring, upper and lower surfaces, the inclination angle of the nozzle 5 can be adjusted, which can ensure that the air flow drills into the gap at the optimal angle, thereby increasing the outer support force of the air flow on the cortex; compared with the traditional manual cleaning and peeling operation, this peeling method can save a lot of manpower and improve safety.

[0039] Furthermore, the guide unit includes a guide ring 6, and a guide groove is formed on the end surface of the guide ring 6. The guide groove consists of a first arcuate groove 7, two second arcuate grooves 8 and a third arcuate groove 9. The first arcuate groove 7 is used to make the direction of the nozzle 5 match the outer wall of the metal ring 23, the second arcuate 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 arcuate groove 9 is used to make the direction of the nozzle 5 match the inner wall of the metal ring 23;

[0040] In the present invention, Figure 6 As 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 curvature, center position and other data 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 by 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 flat, 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 by the nozzle 5 only needs to be blown onto the metal ring 23 to make the airflow 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.

[0041] Furthermore, the opening shape of the nozzle 5 is wavy;

[0042] By setting the opening of the nozzle 5 into a wave shape, 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.

[0043] Furthermore, the fixed arm 4 passes through the support column 3 and slides relatively thereto, and a plurality of sliding columns 11 are slidingly 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 to the corresponding fixed arm 4;

[0044] The support column 3 and the upper fixed arm 4 are connected via an elastic body 12;

[0045] Since different positions on the guide ring 6 have different guiding effects on the nozzle 5, the distance between the support column 3 and the guide ring 6 is not equal on any surface where the axis of the rotating ring 2 is located, that is, when the support column 3 and the nozzle 5 follow the rotating ring 2 for circular motion, the fixed arm 4 needs to slide on the support column 3 to ensure that the guide ring 6 always has a guiding effect on the nozzle 5; to achieve the above purpose, the elastomer 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 guide groove on the guide ring 6, thereby ensuring the normal operation of the equipment; the setting of 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.

[0046] Furthermore, the air blowing unit 1 further comprises a delivery unit for delivering gas to the nozzle 5;

[0047] The conveying unit includes an annular chamber consisting 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. The outer circular groove 13 is connected to the external air path.

[0048] The nozzle 5 is connected to the inner shielding ring 14 through a pipe, and the nozzle 5 is connected to the annular chamber through the pipe;

[0049] Since the rotating ring 2 needs to drive several nozzles 5 to perform circular motion, and the nozzles 5 need to continuously exhaust gas outward, a special conveying unit needs to be set up for the nozzles 5 to meet the movement requirements of the nozzles 5; here, the annular chamber and pipeline composed of the outer circular groove 13 and the inner shielding ring 14 can be used to provide gas for the nozzles 5, and when the nozzles 5 rotate, the inner shielding ring 14 will move synchronously, thereby ensuring a continuous and normal supply of gas; in order to simplify the movement method, 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 structure above it to move synchronously.

[0050] Furthermore, the rotating ring 2, the guide ring 6, the outer circular groove 13 and the inner shielding ring 14 are each composed of two parts, and each part of the rotating ring 2 is fixedly connected to each part of the corresponding inner shielding ring 14;

[0051] Since the metal ring 23 needs to pass through the air blowing unit 1 for circular motion, in order to achieve the normal assembly requirements of the metal ring 23 and the air blowing unit 1, the rotating ring 2, the guide ring 6, the outer circular groove 13 and the inner shielding ring 14 need to be set to a structure consisting of two parts, that is, the air blowing unit 1 is divided into an upper and lower structure. 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 are close to each other and docked together. When the metal ring 23 is removed, the two parts of the air blowing unit 1 can be separated from each other.

[0052] Furthermore, each part of the outer circular groove 13 is provided with at least one set of power sources, which are used to provide power to each part of the corresponding inner shielding ring 14;

[0053] Since the air blowing unit 1 is divided into two parts, the upper and lower parts, in order to ensure that the rotating ring 2 can operate normally and avoid separation of a part of the inner shielding ring 14 from a part of the corresponding outer circular groove 13, it is necessary to set at least one group of power sources on each part of the outer circular groove 13. In this way, the power source is used to provide a locking effect for the inner shielding ring 14, ensuring that in the natural state, a part of the inner shielding ring 14 can be firmly fixed on a part of the corresponding power motor 15, and multiple groups of power sources can be used to continuously provide power for the rotation of the rotating ring 2 and the inner shielding ring 14; the power source can be composed of a transmission wheel 16 installed on each part of the outer circular groove 13 and a buckle cover 17 installed at the output end of the transmission wheel 16, and the buckle cover 17 is connected to the corresponding part of the inner shielding ring 14 in a transmission manner.

[0054] Furthermore, the cleaning unit also includes a housing and an adjustment unit. The housing is composed of two buckle covers 17 distributed upper and lower. Each part of the guide ring 6 and each part of the outer circular groove 13 are installed in the corresponding buckle covers 17. A discharge hopper 18 for discharging debris is provided at the bottom of the lower buckle cover 17.

[0055] The adjustment unit includes a back plate 19 and two movable platforms 20 slidably mounted on the back plate 19. The two movable platforms 20 are fixedly connected to the two buckle covers 17 respectively. A driving disk 21 is rotatably provided on the back plate 19. The driving disk 21 and the two movable platforms 20 are rotatably connected via eccentrically arranged push-pull arms 22.

[0056] The housing is composed of two buckle covers 17, which can provide a mounting position for the two parts of each air blowing unit 1. The guide ring 6 and the outer circular groove 13 are fixed in the corresponding buckle covers 17. When the two buckle covers 17 are separated from or approached, the two parts of the air blowing unit 1 are separated from or approached. The discharge hopper 18 installed at the bottom of the housing can be used to provide a discharge channel for the oxide scale debris after peeling, thereby preventing the oxide scale from being deposited in the housing and affecting the normal operation of its internal structure.

[0057] The back plate 19 and the two movable platforms 20 can provide support for the two buckle covers 17, and the back plate 19 can be installed on an external ring rolling machine; the driving disk 21 can drive the two movable platforms 20 and the two buckle covers 17 to move synchronously relative to each other through the two push-pull arms 22, thereby positioning the midpoint position between the two buckle covers 17, and the rotation of the driving disk 21 can be powered by an external drive motor.

[0058] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
