Description

Technical Field

[0001] The present invention relates to the technical field of forging equipment, and in particular to a forging processing equipment for pressure vessel forgings with impurity removal. Background Art

[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Special forging equipment is required for forging treatment during the production and processing of pressure vessels.

[0003] As a pressure-bearing closed device, professional forging equipment is needed for the forgings of pressure vessels during production and processing. At present, most existing forging equipment relies on the forging head to hammer the workpiece into shape. However, during the high-temperature forging process, an oxide layer is extremely likely to form on the surface of the workpiece. This not only reduces the surface finish and dimensional accuracy of the forging, affecting subsequent processing and assembly, but also may form stress concentration points, weakening the mechanical properties of the forging and threatening the safety and service life of the pressure vessel. Therefore, we provide a forging processing equipment for pressure vessel forgings with impurity removal to solve the above problems. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting up the cooperation of parts such as the driving motor, when a circular workpiece needs to be forged, the circular workpiece can be placed on the top of the support seat, and then the four first hydraulic cylinders are started to drive a curved pressure plate to press on the four sides of the circular workpiece, so as to limit the circular workpiece. After the circular workpiece is hammered and forged by the forging head, when the forging head is reset, a driving motor can be started first, and the output end of the driving motor drives a spur gear to rotate, thereby driving the spur gear ring to drive the symmetrical support plate to rotate in a circle. When the rotating curved pressure plate is aligned with the non-rotating arc pressure plate, the arc pressure plate is rotated. When the two moving arc-shaped pressure plates come into contact, one drive motor stops and the other drive motor starts, thereby driving the other two arc-shaped pressure plates to rotate in a circular motion, thereby scraping the four sides of the circular workpiece, effectively removing impurities such as oxide scale, burrs, and flash generated during the forging process. If these impurities are not removed, they may cause surface defects on the workpiece, affect the subsequent processing accuracy, or cause stress concentration problems. Through the continuous scraping of the arc-shaped pressure plates, the roughness of the workpiece periphery can be improved, making its surface smoother and flatter, reducing the workload of subsequent machining (such as turning and grinding), and reducing material loss and processing costs;

[0015] 2. By arranging the cooperation of parts such as T-shaped blocks, when the support plate rotates in a circle, the T-shaped blocks are driven to rotate synchronously, so that the ball moves up and down along the arch block, thereby pushing the arc-shaped pressure plate to move up and down to scrape, thereby expanding the scraping effect on the surface of circular workpieces and solving the problem of blind spots in cleaning irregular surfaces caused by traditional fixed-height scraping.

[0016] 3. By arranging the cooperation of the spherical rod and other parts, when the arc pressure plate starts to move, the second hydraulic cylinder is started first, and the output end of the second hydraulic cylinder drives the connecting rod to drive the arched scraper to move toward the circular workpiece. When the front end of the arched scraper moves to above the circular workpiece, the spherical rod moves to the highest point of the inclined surface of the front end of the trapezoidal block, so that when the arched scraper continues to move, the first power spring is no longer subjected to the lifting force, so that the arched scraper is pressed tightly against the top of the circular workpiece under the action of the first power spring, so that the arc pressure plate drives the arched scraper to actively scrape the top edge of the circular workpiece during the circular rotation. The curved surface of the arched scraper fits tightly with the edge of the workpiece, and can continuously scrape off raised flash and burrs along the circumferential direction, thereby improving the cleaning effect of the circular workpiece.

[0017] 4. By arranging the arched scraper and other parts to cooperate, when the arched scraper encounters a large obstacle during the circular rotation, the torsion spring can be driven by the rotating shaft to twist, thereby achieving the arched scraper to avoid, thereby preventing the arched scraper from hard contact and causing breakage, thereby improving the overall practicality of the device;

[0018] 5. By setting the cooperation of parts such as the limit pin, since the diameter of the jacking hole is larger than that of the limit pin, when the diameter of the circular workpiece becomes larger during the hammering process, the arc-shaped pressing plate can contract adaptively, and the circular workpiece will not generate too much extrusion force on the arc-shaped pressing plate, thus playing a protective role for the device.

The embodiments of the present invention will be described below according to its overall structure.

[0032] Please refer to Figures 1 to 10, this embodiment provides a forging processing equipment for pressure vessel forgings with impurity removal, including: a forging table 1 and a forging head 4 installed inside the forging table 1. A support seat 2 is fixedly connected to the top inside the forging table 1, and a circular workpiece 3 is placed on the top of the support seat 2; a supporting mechanism, located on the top of the support seat 2, the supporting mechanism includes four support plates 10 arranged on the top of the support seat 2. An adjusting auxiliary device is arranged at the bottom of the support plate 10, and an L-shaped seat 12 is arranged at the top of the support plate 10. A reciprocating lifting assembly is arranged between the support plate 10 and the L-shaped seat 12. A first hydraulic cylinder 13 is installed inside the L-shaped seat 12. The output end of the first hydraulic cylinder 13 penetrates to the inside of the L-shaped seat 12 and is fixedly connected to a fixed sleeve 17. A sliding rod 6 is slidably connected inside the fixed sleeve 17, and one end of the sliding rod 6 is fixedly connected to an arc-shaped pressing plate 5. A locking assembly is arranged between the sliding rod 6 and the fixed sleeve 17. The adjusting auxiliary device includes two straight gear rings 9 rotatably connected to the top of the support seat 2, and each two support plates 10 are fixedly connected to one straight gear ring 9. Two installation holes 21 are opened on the top of the support seat 2, and a driving motor 20 is installed inside each of the two installation holes 21. The output end of the driving motor 20 is fixedly connected to a straight gear 19, and the two straight gears 19 are respectively meshed with one straight gear ring 9;

[0033] Inclined surfaces for scraping are arranged around the arc-shaped pressing plate 5. The two support plates 10 fixed on the top of each straight gear ring 9 are symmetrically arranged. The forging head 4 is driven to move up and down by a hydraulic driving component. Since it is prior art, this solution is not described in detail here. First, when it is necessary to forge the circular workpiece 3, the circular workpiece 3 can be placed on the top of the support seat 2. Subsequently, four first hydraulic cylinders 13 are started, so as to drive an arc-shaped pressing plate 5 to press on the four sides of the circular workpiece 3 respectively, thereby limiting the circular workpiece 3. When the forging head 4 descends to hammer and forge the circular workpiece 3, when the forging head 4 is reset, a driving motor 20 can be started first. The output end of the driving motor 20 drives a straight gear 19 to rotate, thereby driving the straight gear ring 9 to drive the symmetrically arranged support plates 10 to rotate circumferentially. When the rotating arc-shaped pressing plate 5 contacts the non-rotating arc-shaped pressing plate 5, one driving motor 20 stops, and the other driving motor 20 starts, so as to drive the other two arc-shaped pressing plates 5 to rotate circumferentially, thereby scraping the four sides of the circular workpiece 3, effectively removing impurities such as scale, burrs, and flash generated during the forging process. If these impurities are not removed, they may cause surface defects of the workpiece, affect the subsequent processing accuracy, or cause stress concentration problems, so that the arc-shaped pressing plate 5 can not only be used to limit the circular workpiece 3 during actual use, but also scrape the outer wall of the circular workpiece 3 during actual use;

[0034] The above-mentioned circumferential scraping operation is implemented during each hammering and lifting process of the forging head 4.

[0035] See also Figures 2 to 6 The reciprocating lifting assembly includes a T-shaped block 11 slidably connected to the inner side of the support plate 10, a connecting spring 22 is installed between the T-shaped block 11 and the support plate 10, and the T-shaped block 11 is fixedly connected to the L-shaped seat 12, the bottom of the T-shaped block 11 is fixedly connected to a connecting column 23, and a ball 24 is embedded in the bottom of the connecting column 23. The outer wall of the support seat 2 is fixedly connected to a fixing ring 7, and the top of the fixing ring 7 is fixedly connected to a plurality of arched blocks 8, and the plurality of arched blocks 8 are distributed equidistantly around the top of the fixing ring 7;

[0036] When the support plate 10 rotates in a circle, it drives the T-shaped block 11 to rotate synchronously, so that the ball 24 moves up and down along the arch block 8, thereby pushing the arc pressure plate 5 to move up and down to scrape, thereby expanding the scraping effect on the surface of the circular workpiece 3 and solving the blind spot problem of cleaning irregular surfaces with traditional fixed height scraping.

[0037] See also Figures 1 to 10 , the scraping assembly is located on the inner side of the L-shaped seat 12, and the scraping assembly includes a sliding seat 15 slidably connected to the inner side of the L-shaped seat 12, one end of the sliding seat 15 is slidably connected to the connecting rod 18, and the front end of the connecting rod 18 is provided with an arched scraper 32. A second hydraulic cylinder 14 is installed on one side of the L-shaped seat 12, and the output end of the second hydraulic cylinder 14 passes through the inner side of the L-shaped seat 12 and is fixedly connected to the sliding seat 15. An adaptive swing unit is provided between the arched scraper 32 and the connecting rod 18. The scraping assembly also includes a link 18 and a link 18. The first power spring 35 between the sliding seats 15, the bottom of the connecting rod 18 is fixedly connected to a spherical rod 36, and one end of the spherical rod 36 extends to the outside of the sliding seat 15, the inner side of the L-shaped seat 12 is fixedly connected to the trapezoidal block 16, and the spherical rod 36 abuts against the top of the trapezoidal block 16, the adaptive swing unit includes a rotating shaft 33 fixedly connected to the top of the arched scraper 32, and one end of the rotating shaft 33 extends to the top of the connecting rod 18 and is rotatably connected to the connecting rod 18, and a torsion spring 34 is installed between the rotating shaft 33 and the connecting rod 18;

[0038] When the arc pressure plate 5 moves, the second hydraulic cylinder 14 is started first, and the output end of the second hydraulic cylinder 14 drives the connecting rod 18 to drive the arched scraper 32 to move in the direction of the circular workpiece 3. When the front end of the arched scraper 32 moves to above the circular workpiece 3, the spherical rod 36 moves to the highest point of the inclined surface of the front end of the trapezoidal block 16, so that when the arched scraper 32 continues to move, the first power spring 35 is no longer subjected to the lifting force, so that the arched scraper 32 is pressed against the top of the circular workpiece 3 under the action of the first power spring 35, so that the arc pressure plate 5 drives the arched scraper 32 to actively scrape the top edge of the circular workpiece 3 during the circumferential rotation. The curved surface of the arched scraper 32 fits tightly with the edge of the workpiece, and can continuously scrape off raised burrs and burrs along the circumferential direction, thereby improving the cleaning effect of the circular workpiece 3.

[0039] When the arched scraper 32 encounters a large obstacle during circumferential rotation, the torsion spring 34 can be driven by the rotating shaft 33 to twist, so as to realize the avoidance of the arched scraper 32, thus avoiding hard contact of the arched scraper 32 and causing fracture, thereby improving the overall practicability of the device;

[0040] When the arched scraper 32 is pressed against the top of the circular workpiece 3 under the action of the first power spring 35, since the L-shaped seat 12 moves up and down reciprocally, when the L-shaped seat 12 moves upward, under the action of the first power spring 35, the arched scraper 32 is always pressed against the top edge of the circular workpiece 3;

[0041] During the implementation of the above solution, structures such as the sliding seat 15, the second hydraulic cylinder 14, and the trapezoidal block 16 can also be directly fixed to the top of the support plate 10 through a frame similar to the L-shaped seat 12; ]>

[0042] Please refer to Figures 7 to 9 , the locking assembly includes a limit pin 28 slidably connected inside the fixed sleeve 17. One end of the limit pin 28 penetrates to the outside of the fixed sleeve 17 and is fixedly connected with a cylinder 27. An auxiliary spring 29 is installed between the cylinder 27 and the fixed sleeve 17. A plurality of inwardly recessed jacks 31 are formed on one side of the sliding rod 6. A second power spring 37 is installed between the sliding rod 6 and the fixed sleeve 17. The plurality of jacks 31 are equidistantly distributed on one side of the sliding rod 6, and the diameters of the plurality of jacks 31 are larger than the diameter of the limit pin 28. The locking assembly further includes a power rod 25 fixedly connected to one side of the sliding seat 15. A plurality of rollers 26 are rotatably connected to the inside of the power rod 25. An inclined groove 30 is formed inside the cylinder 27;

[0043] When the sliding seat 15 moves towards the circular workpiece 3, it drives the power rod 25 to move synchronously. When the roller 26 contacts the inner inclined surface of the inclined groove 30, it pushes the cylinder 27 to drive the limit pin 28 out of the inside of the jack 31, so that the sliding rod 6 is no longer fixed to the fixed sleeve 17. Since the diameter of the circular workpiece 3 expands during hammering, when the sliding rod 6 drives the arc-shaped pressing plate 5 to rotate circumferentially, it can be adaptively adjusted through the second power spring 37, so that the device can scrape the outer wall and the top edge of the circular workpiece 3 after hammering at different stages, thereby improving the overall applicability of the device;

[0044] And when the circular workpiece 3 needs to be forged, the second hydraulic cylinder 14 is reset, so that the limit pin 28 is inserted into the jack 31 to play a limiting function;

[0045] Moreover, since the diameter of the jack 31 is larger than that of the limit pin 28, when the diameter of the circular workpiece 3 increases during hammering, the arc-shaped pressing plate 5 can contract adaptively, and the circular workpiece 3 will not generate excessive extrusion force on the arc-shaped pressing plate 5, thus playing a protective role for the device.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
