Description

Technical Field

[0001] The invention relates to the technical field of forging processing, in particular to a tube forging processing device. Background Art

[0002] Cylinder forgings are a type of mechanical parts made through a forging process. They have the characteristics of high strength, high toughness and high wear resistance. They are widely used in large-scale mechanical equipment, lifting equipment, metallurgy, chemical industry, engineering, offshore shipbuilding, aerospace and other fields, mainly playing a slewing bearing or guiding role.

[0003] During the production process of cylindrical forgings, the outer ring surface of the metal blank of the cylindrical forging needs to be forged by a forging hammer to shape it and improve its strength and toughness. When forging large cylindrical forgings, such cylindrical forgings are usually transported and mounted on a rotating support column connected to a forging manipulator. The rotating support column is controlled to rotate at a small angle, and the cylindrical forging is driven to rotate with the rotating support column by the gravity of the cylindrical forging itself and the friction between the inner circumference of the cylindrical forging and the support column, thereby adjusting the different forging positions of the cylindrical forgings.

[0004] During the forging process of cylindrical forgings, a layer of oxide scale will be formed on the surface of the metal due to the high temperature and mechanical force. Part of the formed oxide scale will fall off by itself during the rotation of the cylindrical forging, and the other part will adhere to the surface of the cylindrical forging. This part of the oxide scale that has not fallen off will move back to the bottom of the forging hammer as the cylindrical forging rotates. As the forging hammer is forged again, this part of the oxide scale will be pressed into the surface of the cylindrical forging again, making the surface of the cylindrical forging rougher, thereby affecting the surface quality of the cylindrical forging and making it difficult to meet the processing requirements. Therefore, it is necessary to remove this part of the oxide scale that has not fallen off in time.

[0005] At present, the cleaning process of the oxide scale produced by forgings is mainly divided into two methods: automatic cleaning and manual cleaning. Automatic cleaning uses mechanical or chemical means to remove the oxide scale. Specifically, mechanical cleaning refers to grinding and polishing the oxide scale on the surface of the cylindrical forgings by a rotating grinding wheel or a cleaning drum, and chemical cleaning refers to the use of pickling to dissolve and remove the oxide scale. These automatic cleaning processes usually need to be completed after the forging operation of the forgings is completed. The removal process cannot be removed during the forging process. For the forging of cylindrical forgings, there is still a problem that the oxide scale cannot be effectively and timely removed, so that the oxide scale will be pressed into the surface again with the rotating cylindrical forgings. Manual cleaning is usually carried out during the forging process, using a manual handheld high-pressure purge device or a scraper device to timely remove the oxide scale produced on the surface of the rotating cylindrical forgings. However, the manual cleaning operation requires constant adjustment of the cleaning area and cleaning angle, which undoubtedly increases the labor intensity, and the manual forging environment is dangerous. The noise, high temperature and oxide scale particles splashing during the hammering process will cause harm to human health. Summary of the invention

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the invention, unless otherwise specified, "plurality" means two or more.

[0032] Example like Figures 1 to 10As shown, an embodiment of the present invention provides a cylindrical forging processing device, including two support arms 1 connected to a manipulator and a rotatable support column 2, the two support arms 1 are arranged horizontally and parallel, the rotatable support column 2 is arranged horizontally between the two support arms 1, a first cleaning mechanism is arranged on the support arm 1, the first cleaning mechanism includes an arc-shaped box body 3 and a rotating part, the inner arc wall of the arc-shaped box body 3 is arranged toward the side wall of the rotatable support column 2, and a plurality of nozzles 31 are evenly distributed on the inner arc wall, a first joint 32 for connecting to a high-pressure airflow delivery pipe is provided at the bottom of the arc-shaped box body 3, the rotating part includes a connecting frame 41, two arc-shaped guide rails 42, a first rack 44, a reset spring 45 and a gear transmission assembly 46, the connecting frame 41 is connected to the support arm 1, and the two arc-shaped guide rails 42 are arranged On both sides of the arc box 3, and slidingly connected with the two side walls of the arc box 3, the two arc guide rails 42 are fixed to the connecting frame 41, and a plurality of meshing teeth 43 are evenly distributed on the outer arc wall of the arc box 3 between the two arc guide rails 42. The first rack 44 is arranged on the opposite side of the plurality of meshing teeth 43, and the top of the first rack 44 is provided with a connecting assembly for detachably connecting with the side wall of the forging hammer. The reset spring 45 is arranged at the bottom of the first rack 44, and the two ends are respectively connected to the first rack 44 and the connecting frame 41, and the gear transmission assembly 46 is meshed and connected between the first rack 44 and the plurality of meshing teeth 43, and is used for converting the reciprocating vertical movement process of the first rack 44 into the reciprocating rotation process of the arc box 3 when the first rack 44 moves up and down with the forging hammer through the connecting assembly.

[0033] In this embodiment, the first cleaning mechanism is provided to realize the function of automatically cleaning the oxide scale generated during the forging process of the cylindrical forgings. The device is arranged on the operating machine as a whole. During forging, the cylindrical forgings to be forged are placed on the rotating support column 2, and the cylindrical forgings are moved to the bottom of the hydraulic forging machine by the operating machine. The first rack 44 is connected to the side wall of the forging hammer through the connecting assembly. When the cylindrical forgings are reciprocated and lifted by the forging hammer, the first rack 44 moves synchronously with the forging hammer through the connecting assembly. During the movement, the first rack 44 drives the multiple meshing teeth 43 arranged on the arc box 3 through the gear transmission assembly 46, so that the arc box 3 can reciprocate along the arc guide rail 42 in an arc trajectory. The first joint 32 provided at the bottom of the arc-shaped box body 3 is connected to the external high-pressure airflow delivery pipe, and the high-pressure airflow is delivered to the arc-shaped box body 3 by a booster pump and sprayed out through multiple nozzles 31, so as to timely clean the oxide scale generated on the outer ring surface of the cylindrical forging after forging. Since the rotating support column 2 will drive the cylindrical forging to flip a certain angle in one direction after each hammering operation of the forging hammer, and the rotation of the arc-shaped box body 3 is bidirectional reciprocating, when the oxide scale on the cylindrical forging is cleaned by blowing, the blowing angle can be continuously changed, which can not only cover the surface area of ​​the cylindrical forging more effectively, but also can clean some oxide scales that are difficult to be removed in the cleaning dead corners on the uneven surface of the cylindrical forging.

[0034] Specifically, as an optional implementation of the connecting component, the connecting component in this embodiment includes a moving rod 51, a hollow screw 52, ​​an insertion rod 53 and a turning handle 54. One end of the moving rod 51 is fixed to the top of the first rack 44. A threaded hole is provided on the side wall of the moving rod 51. The hollow screw 52 is threadedly connected to the threaded hole provided on the moving rod 51. The insertion rod 53 is fixed on the side wall of the forging hammer and is arranged opposite to the hollow screw 52. The turning handle 54 is fixed to one end of the hollow screw 52 facing away from the insertion rod 53.

[0035] In this embodiment, when the first rack 44 is connected to or disassembled from the side wall of the forging hammer through the connecting assembly, the hollow screw 52 is driven to rotate by rotating the handle 54. Since the hollow screw 52 is threadedly connected to the moving rod 51, the distance between the hollow screw 52 and the insertion rod 53 can be adjusted by rotating the hollow screw 52. When it is necessary to connect to the side wall of the forging hammer, the hollow screw 52 is rotated to insert the insertion rod 53 into the interior of the hollow screw 52. At this time, when the forging hammer is lifted and lowered, it will move synchronously with the hollow screw 52 through the insertion rod 53, thereby driving the moving rod 51 and the first rack 44 to move synchronously, thereby driving the arc box 3 to rotate. When it is necessary to release the connection with the side wall of the forging hammer, the insertion rod 53 is disengaged from the inside of the hollow screw 52 by rotating the hollow screw 52 in the opposite direction, thereby separating the two. At this time, unloading and transfer operations can be performed.

[0036] Further, such as Figure 1 and Figure 3 As shown, the connecting frame 41 includes a sliding sleeve 411, two connecting plates 412 and a bottom plate 413. The sliding sleeve 411 is slidably mounted on the support arm 1. The two connecting plates 412 are arranged in parallel. One end of the two connecting plates 412 is fixed to the side wall of the sliding sleeve 411, and the other ends of the two connecting plates 412 are respectively fixed to the two arc guide rails 42. The bottom plate 413 is fixed to the bottom of the two connecting plates 412. One end of the reset spring 45 away from the first rack 44 is connected to the bottom plate 413. The sliding sleeve 411 is arranged to enable the arc box 3 to move on the support arm 1, so as to facilitate the adjustment of different purging and cleaning positions.

[0037] Specifically, the gear transmission assembly 46 includes a first gear 461 and a second gear 462. The first gear 461 and the second gear 462 are both rotatably mounted between the two connecting plates 412 through a gear shaft. One side of the first gear 461 is meshed with the first rack 44, and the other side of the first gear 461 is meshed with one side of the second gear 462. The other side of the second gear 462 is meshed with a plurality of meshing teeth 43. Through the above arrangement, when the first rack 44 moves up and down, the meshing transmission of the first gear 461 and the second gear 462 is utilized to drive the arc box 3 to rotate, and the arc box 3 is rotated upward when the forging hammer rises, and is rotated downward when the forging hammer descends, thereby avoiding the problem of damage to the arc box 3 caused by being hit by the forging hammer.

[0038] Furthermore, a strip slot 11 is opened on the support arm 1 along its length direction, and a linear moving mechanism 61 is arranged in the strip slot 11. The output end of the linear moving mechanism 61 is connected to a slide 62 for driving the slide 62 to move in the strip slot 11. A clamping assembly 63 for clamping the tubular forging is provided on the side of the slide 62 facing the rotatable support column 2. Through the cooperation of the linear moving mechanism 61 and the clamping assembly 63, the different positions of the tubular forgings in the axial direction of the rotatable support column 2 can be adjusted, thereby adjusting the different hammering positions of the tubular forgings along their length direction, thereby realizing the forging and forming operation of the tubular forgings as a whole.

[0039] Specifically, the clamping assembly 63 includes a first motor 631, a bidirectional lead screw 632 and two clamping jaws 634. The first motor 631 is fixed on the side wall of the slide 62 away from the linear moving mechanism 61. One end of the bidirectional lead screw 632 is connected to the output shaft of the first motor 631. An installation opening is opened inside the slide 62. The other end of the bidirectional lead screw 632 extends into the installation opening and is rotatably connected to the inner wall of the installation opening. Nut seats 633 are respectively connected to both sides of the bidirectional lead screw 632. The two clamping jaws 634 are respectively fixedly connected to the side walls of the two nut seats 633 facing the rotating support column 2, and the sliding sleeve 411 is located between the two clamping jaws 634.

[0040] The clamping assembly 63 in this embodiment can realize the centering clamping function. The first motor 631 drives the bidirectional lead screw 632 to rotate to drive the two nut seats 633 to move synchronously close to or away from each other, thereby driving the two clamping claws 634 to move synchronously, so as to realize the clamping function of the two ends of the cylindrical forging. The adjustment of the linear moving mechanism 61 can drive the cylindrical forging to move axially along the rotating support column 2, so as to adjust the forging position of the cylindrical forging. And because the sliding sleeve 411 is located between the two clamping claws 634, the forging position of the clamping sleeve forging is adjusted. The movement will not interfere with the fixed position of the sleeve 411, thereby ensuring that the sleeve 411 and the arc box 3 maintain their current positions, and the forging area is purged and cleaned. When forging is completed, the first rack 44 is separated from the side wall of the forging hammer through the connecting assembly, so that the position of the sleeve 411 is no longer locked, and then the two clamps 634 and the cylindrical forgings are driven to move in translation through the linear moving mechanism 61 to remove the cylindrical forgings from the rotating support column 2. During this process, the clamps 634 will push the sleeve 411 to slide on the support arm 1 to avoid movement interference between the two.

[0041] Specifically, Figure 2 As shown, as several optional embodiments of the linear moving mechanism 61, the linear moving mechanism 61 is a horizontally arranged multi-stage hydraulic cylinder or a multi-stage electric cylinder, the cylinder body of the multi-stage hydraulic cylinder or the cylinder body of the multi-stage electric cylinder is fixed to the inner wall of the mounting port, and the telescopic rod end of the multi-stage hydraulic cylinder or the telescopic rod end of the multi-stage electric cylinder is fixed to the side wall of the slide 62.

[0042] Specifically, Figure 1 As shown, the rotatable support column 2 includes a rotatable driving part and a support column body 25. The rotatable driving part includes a second motor 21, a third gear 22, a rotating shaft 23 and a fourth gear 24. The second motor 21 is fixed on the mounting frame 7, and the mounting frame 7 is connected to the operating machine. The third gear 22 is fixed on the output shaft of the second motor 21. The rotating shaft 23 is arranged below the second motor 21. One end of the rotating shaft 23 is rotatably connected to the mounting frame 7. The fourth gear 24 is fixed on the rotating shaft 23. The fourth gear 24 is meshed with the third gear 22. One end of the support column body 25 is coaxially fixed with the rotating shaft 23.

[0043] When the cylindrical forging is driven to rotate by the rotatable support column 2, the third gear 22 is driven to rotate by controlling the second motor 21. Since the third gear 22 is meshed with the fourth gear 24, the rotating shaft 23 is synchronously driven to rotate, and then the supporting column 25 is driven to rotate through the rotating shaft 23, thereby realizing the rotation adjustment process of the cylindrical forging.

[0044] In another embodiment of the present invention, Figure 1 and Figure 5As shown, considering that during the forging operation, not only the outer wall of the cylindrical forging will produce oxide scale, but the inner wall of the cylindrical forging will also produce a small amount of oxide scale during forging due to the support reaction force of the support column 25. Therefore, in order to be able to realize the cleaning process of the oxide scale on the inner wall of the cylindrical forging after the forging is completed and reduce the cleaning operation process, a second cleaning component is also provided on the support column 25. The second cleaning component includes an air supply channel 81, a second joint 82 and a plurality of spray holes 83. The end of the rotating shaft 23 away from the support column 25 extends to the outside of the mounting frame 7. The air supply channel 81 is opened at the center of the rotating shaft 23 and the support column 25, and is arranged through the rotating shaft 23. The second joint 82 is arranged on one side of the air supply channel 81 at the end of the rotating shaft 23, and is used to connect with the high-pressure air flow delivery pipe. The end of the support column 25 away from the rotating shaft 23 is provided with a conical surface, and a plurality of spray holes 83 are arranged around the conical surface and are connected with the air supply channel 81.

[0045] In this embodiment, the second joint 82 is connected to the high-pressure airflow conveying pipe. After the cylindrical forging is hammered and formed, the two clamps 634 are used to clamp the cylindrical forging and unload it horizontally from the support column 25. The high-pressure airflow is conveyed through the air delivery channel 81 and sprayed out from the multiple nozzles 83. The multiple nozzles 83 will blow the high-pressure airflow into the inner wall of the cylindrical forging. As the cylindrical forging moves, its entire inner wall is blown and cleaned.

[0046] Further, such as Figure 5 As shown, the spray hole 83 is a tapered hole, and the diameter of the spray hole 83 at the tapered surface is larger than the diameter at the gas delivery channel 81. By setting the spray hole 83 as a tapered hole, the range of the high-pressure airflow ejected from the spray hole 83 can be expanded, so that the oxide scale generated on the entire inner wall of the cylindrical forging can be purged and removed.

[0047] In order to adjust the horizontal spacing between the two support arms 1 so as to realize the clamping and purging operation of cylindrical forgings of different diameters, a spacing adjustment mechanism is provided between the two support arms 1, such as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the spacing adjustment mechanism includes a supporting structure, two parallel four-bar linkage arm structures and a driving structure. The supporting structure includes two mounting plates 91 and a fixing frame 92. The two mounting plates 91 are horizontally arranged on the upper and lower sides of the rotating shaft 23. One side of the fixing frame 92 is fixed to the mounting frame 7, and the other side of the fixing frame 92 is fixed to the two mounting plates 91. The two parallel four-bar linkage arm structures are symmetrically arranged on both sides of the rotating shaft 23 and connected between the two mounting plates 91. One end of the support arm 1 is connected to the parallel four-bar linkage arm structure. The driving structure is connected to each parallel four-bar linkage arm structure for driving each four-bar linkage arm structure to perform translational swing.

[0048] Furthermore, the parallel four-link swing arm structure includes two first links 93 and two second links 94, the two first links 93 are arranged horizontally and in parallel, and one end of the two first links 93 is hinged between the two mounting plates 91 through a hinge shaft, the two second links 94 are respectively arranged in parallel on the upper and lower sides of the two first links 93, and the two ends of the two second links 94 are respectively hinged to the other ends of the two first links 93 through a hinge shaft, one end of the support arm 1 is fixed to the side walls of the two second links 94, the output end of the driving structure is connected to one end of one of the first links 93, and the driving structure is used to drive the first link 93 to rotate around the hinge between it and the mounting plate 91, refer to Figure 7 The two first links 93 constitute two parallel swinging swinging rods in the parallel four-link swing arm structure, and the hinge shafts at the ends of the two first links 93 and the mounting plate 91 constitute the frame of the parallel four-link swing arm structure. The two second links 94 are restricted by the other ends of the two first links 93 to form a translation rod parallel to the frame. In this way, when the first link 93 is driven by the driving structure to rotate around the hinge between it and the mounting plate 91, a parallel swinging process will be realized, thereby ensuring that the support arm 1 can be driven to move translationally.

[0049] Specifically, as an optional implementation of the drive structure, the drive structure in this embodiment includes a hydraulic telescopic component and two sets of transmission components. The hydraulic telescopic component includes a cylinder body 95, a piston 96, a piston rod 97 and a hydraulic drive unit arranged on the cylinder body 95. Through holes are provided at both ends of the cylinder body 95. The piston 96 is slidably connected in the cylinder body 95. One end of the piston rod 97 is fixedly connected to the piston 96, and the other end of the piston rod 97 extends to the outside of the cylinder body 95 through the through hole. The piston 96 and the piston rod 97 are hollow structures. The rotating shaft 23 is penetrated inside the piston 96 and the piston rod 97 and is slidably connected between the piston 96 and the piston rod 97. The outer wall of the cylinder body 95 is fixed to the fixed frame 92. The two sets of transmission components are symmetrically arranged on both sides of the piston rod 97. The transmission component includes a second rack 98 and an incomplete gear 99. The second rack 98 is fixed on the side wall of the piston rod 97. The incomplete gear 99 is fixed to the end of the first connecting rod 93 close to the second rack 98, and the incomplete gear 99 is meshed with the second rack 98.

[0050] Among them, Figure 5 and Figure 6 As shown, the hydraulic drive unit includes inlet and outlet liquid channels 951 opened on both sides of the bottom of the cylinder body 95, and an interface 952 is provided at the end of the inlet and outlet liquid channels 951 at the bottom of the cylinder body 95. The interface 952 is connected to an external hydraulic pump through a connecting pipeline, and the hydraulic pump provides high-pressure liquid to drive the piston 96.

[0051] The piston rod 97 and the through hole of the cylinder body 95 are connected in a sliding and sealing manner, and the rotating shaft 23 and the through hole of the cylinder body 95 and the rotating shaft 23 and the piston rod 97 are all connected in a sliding and sealing manner to prevent leakage of the injected hydraulic oil.

[0052] In this embodiment, when the four-bar linkage swing arm structure is driven to translate and swing through the driving structure, the piston 96 is controlled to slide in the cylinder body 95 through the hydraulic driving unit. The sliding of the piston 96 drives the piston rod 97 to move synchronously. When the piston rod 97 moves, it drives the second rack 98 to move. Since the second rack 98 is meshed with the incomplete gear 99, it can drive the incomplete gear 99 and the first connecting rod 93 to rotate around the hinge axis, thereby realizing the translation and swinging process of the parallel four-bar linkage swing arm structure. Moreover, since the piston 96 and the piston rod 97 are hollow structures, the rotating shaft 23 can directly pass through the piston rod 97, so that the entire driving structure is integrated on the rotating shaft 23, which can make the device more compact and reduce the occupied space.

[0053] In summary, the present invention can realize the function of timely and automatic cleaning of the oxide scale generated during the forging and forming process of the cylindrical forgings through the first cleaning mechanism provided. The first cleaning mechanism is implemented by an arc-shaped box body and a rotating part. The oxide scale generated during the forging of the cylindrical forgings is blown and removed in time by using multiple nozzles provided on the arc-shaped box body to spray high-pressure airflow. The arc-shaped box body is driven by the rotating part to reciprocate and the blowing angle can be continuously changed. Compared with single-angle blowing, it can not only more effectively cover the surface area of ​​the cylindrical forgings, but also reduce the problem of incomplete cleaning caused by some cleaning dead corners when uneven areas appear on the surface of the cylindrical forgings. The rotating part relies on the forging hammer in the hydraulic forging machine as the power driving source, and synchronously drives the arc-shaped box body to rotate with the lifting and lowering of the forging hammer, which can not only reduce the production cost, but also avoid the problem of damage to the arc-shaped box body caused by being hit by the forging hammer.

[0054] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
