[0013] The present invention also discloses a production process of a large-scale die forging special die forging, which is produced by using a forging device for a large-scale die forging special die forging, and includes the following steps: S1: When forging, the forging is placed on a placement table, and the placement table is forced to rotate downward around the first pin shaft, and the stopper can limit the forging sliding down along the inclined placement table; S2: When the placement table rotates downward, it drives the arc-shaped rack to mesh with the driven gear for transmission, the driven gear drives the rotating rod to rotate, the rotating rod drives the reel to wind up the first pull rope, when the first pull rope is wound up, it applies force to pull the scraper away from the plate body of the slider, the plate bodies contract with each other, so that the length of the scraper is reduced, after the scraper is reduced to the shortest, the first pull rope applies tension to the slider through the scraper, the slider slides in the frame, the first elastic element is stretched, when the scraper moves from the left side of the placement table to the right side, the scraper contacts the block and the forging, the scraper is automatically flipped relative to the slider under force, and the shortened scraper can quickly pass over the forging to reach the other side of the placement table; S3: When the placement table is forced to rotate downward, the first elastic telescopic rod contracts and applies tension to the second pull rope, so that the stopper contracts into the placement table; S4: As the placement table and the frame are flipped, the frame is plugged into the arc-shaped limit plate through the concave hole until the placement table abuts against the top planes of the first support and the second support, and the placement table is in a horizontal state. At this time, the arc-shaped rack is no longer meshed with the driven gear, and the rotating rod drives the reel to reset and rotate under the action of the torsion spring. The reel releases the first pull rope, the scraper length is restored, and the slider moves back under the pull of the first elastic element until the slider abuts against the arc-shaped limit plate, limiting the slider from moving back to the upper side of the placement table, and at this time the top of the block is in the same plane as the top surface of the placement table, and the first pneumatic telescopic rod is plugged into the block to limit the position; S5: Control the hydraulic equipment to drive the press seat to forge the forging on the forging table; S6: After the forging is forged, the forging is removed from the forging table by a forklift using a clamp.

When the placement table drives the frame to rotate upward, the frame moves away from the arc-shaped limit plate. The slider is no longer subjected to force and is reset and moved back under the pull of the first elastic element, so that the slider drives the scraper to scrape the oxidized debris remaining on the forging until the scraper moves from the right end of the placement table to the left end. The scraper abuts against the movable rod of the second pneumatic telescopic rod, and the second pneumatic telescopic rod contracts and introduces the air inside it into the air cavity of the first pneumatic telescopic rod through the air guide tube, so that the first pneumatic telescopic rod contracts and releases the limit of the first pneumatic telescopic rod on the block. The block is reset to prepare for the limit when other forgings are subsequently lowered; S7: Repeat S1-S6 to achieve continuous forging of other subsequent forgings by the forging equipment.

[0014] Compared with the prior art, the present invention provides a production process for large die forging special die forgings and a forging equipment thereof, which has the following beneficial effects: 1.

The production process of large die forging special die forgings and the forging equipment thereof can prevent the forgings from sliding down and falling on the inclined placement table when the forgings are placed on the placement table by setting a stopper on the placement table, and after the placement table is placed horizontally under the pressure of the forgings, the first pneumatic telescopic rod limits the stopper to prevent the stopper protruding from the placement table from affecting the movement of the forgings on the placement table during forging and the removal effect of the oxidized debris on the placement table when the scraper is reset and moved back; 3. The production process of large-scale die forging special die forgings and its forging equipment, by rotating the placement table downward to make the scraper move from one end of the placement table to the other end, the scraper automatically shrinks in length, so that the shortened scraper can quickly pass over the forging to reach the other side of the placement table, avoiding the scraper being too long, resulting in a long time for the scraper to pass over the forging on the placement table and an overly long frame design, effectively reducing the size of the forging equipment and improving the forging efficiency.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a forging device for large die forging special die forgings, including a frame 1, and also including: The forging part includes a hydraulic device 2 fixed on the top of the frame 1 and a pressing seat 201 arranged at the output end of the hydraulic device 2; The forging table 3 includes a placing table 301 placed at the lower side of the pressing seat 201, a first support 302 fixed to the lower part of the frame 1 and rotatably connected to the placing table 301 through a first pin 3021, and a push assembly arranged between the bottom of the placing table 301 and the frame 1. The frame 1 is provided with a plurality of second supports 303 for supporting the placing table 301; A scraping mechanism, which is disposed on the placement table 301 and is used to clean the oxidized debris on the placement table 301; The frame 1 is also provided with a driving component for driving the scraping mechanism.

[0020] Furthermore, the push assembly includes a first elastic telescopic rod 4 fixed to the lower side of the frame 1 and a slide 401 rotatably connected to the top of the first elastic telescopic rod 4 through a pin shaft, and a slide groove 3011 for sliding the slide 401 is provided at the bottom of the placement table 301.

[0021] Specifically, at the beginning, the first elastic telescopic rod 4 pushes the placement table 301 to be lifted up, so that the placement table 301 is tilted relative to the first support 302, so that when the subsequent forging is completed and removed, the oxidized debris automatically falls from the tilted placement table 301. When the forging is forged, the forging is placed on the placement table 301, and the placement table 301 is forced to rotate downward with the first pin shaft 3021 as the center. The first elastic telescopic rod 4 contracts to buffer the lowering force of the forging to avoid excessive impact on the placement table 301 when the forging is lowered, resulting in a reduction in the service life of the placement table 301 and the frame 1. When the placement table 301 flips and moves downward, the driving component automatically works and drives the scraping mechanism to move from one end of the placement table 301 to the other end. After being placed horizontally, the first support 302 and the second support 303 support the bottom of the placement table 301, and then the hydraulic equipment 2 drives the press seat 201 to complete the forging of the forging. When the forging is removed from the placement table 301, the scraping mechanism can automatically remove the oxidized debris generated by forging on the forging table 3, without the need for manual cleaning by the staff, thus shortening the waiting time between the forging of two forgings and improving the overall forging efficiency of multiple forgings. It should be noted that the inclined setting of the placement table 301 allows most of the oxidized debris on the placement table 301 to fall off automatically. Otherwise, when a large amount of oxidized debris is pushed away by the scraping mechanism alone, a part of the oxidized debris will accumulate due to scraping and then pass over the scraping mechanism and fall on the other side of the scraping mechanism, resulting in residual oxidized debris on the placement table 301.

[0022] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 and Fig.10, a forging equipment for large-scale die forging special die forgings, based on Example 1, further, the driving component includes an ear plate 5 fixedly mounted on the frame 1, a rotating rod 501 rotatably connected to the ear plate 5, a driven gear 502 and a reel 503 arranged on the rotating rod 501, and a first pull rope 504 wound around the reel 503, an arc-shaped rack 6 meshing with the driven gear 502 is fixedly arranged at the bottom of the placement table 301, the driven gear 502 is arranged as a one-way gear, the arc-shaped rack 6 and the central axis of the first pin shaft 3021 are in the same straight line, and a torsion spring is arranged between the rotating rod 501 and the ear plate 5.

[0023] Furthermore, the scraping mechanism includes a frame 7 fixed on the side of the placement table 301, a slider 701 slidably connected in the frame 7 and connected to the first pull rope 504, a first elastic element 702 arranged between the inner wall of the frame 7 and the slider 701, and a scraper 704 connected to the slider 701 by unidirectional rotation through a second pin shaft 703.

[0024] Furthermore, an arc-shaped limiting plate 8 that movably contacts the slider 701 is fixedly disposed on the frame 1 , and a concave hole 801 for the movement of the arc-shaped limiting plate 8 is formed at the bottom of the frame body 7 .

[0025] Specifically, the forging is placed on the placement table 301, and the placement table 301 is subjected to force and rotates downward with the first pin shaft 3021 as the center. When the placement table 301 rotates downward, it drives the arc rack 6 to mesh with the driven gear 502 for transmission, and the driven gear 502 drives the rotating rod 501 to rotate, and the rotating rod 501 drives the reel 503 to reel the first pull rope 504. When the first pull rope 504 is reeled, a pulling force is applied to the slider 701, and the slider 701 slides in the frame 7, and the first elastic element 702 is When the scraper 704 moves from the left side to the right side of the placement table 301, the scraper 704 contacts the stopper 901 and the forging, and the scraper 704 automatically flips relative to the slider 701 under force. As the slider 701 continues to move, the slider 701 drives the scraper 704 to pass over the forging and move to the other end of the placement table 301. As the placement table 301 and the frame 7 flip, the frame 7 is plugged into the arc-shaped limit plate 8 through the concave hole 801 until the placement table 301 is aligned with the first support 302 and the second support The top plane of the seat 303 is abutted, and the placement table 301 is in a horizontal state. At this time, the arc-shaped rack 6 is no longer meshed with the driven gear 502. The rotating rod 501 drives the reel 503 to rotate back under the action of the torsion spring. The reel 503 releases the first pull rope 504, the length of the scraper 704 is restored, and the slider 701 moves back under the pull of the first elastic element 702 until the slider 701 abuts against the arc-shaped limit plate 8, limiting the slider 701 from moving back to the upper side of the placement table 301. After completion, the forging is removed from the placing table 301, and the placing table 301 moves upward under the elastic force of the first elastic telescopic rod 4. The inclined placing table 301 is convenient for the oxidized debris to fall off quickly, and the slider 701 drives the scraper 704 to move back under the pull of the first elastic element 702. The scraper 704 further cleans the oxidized debris on the placing table 301, and there is no need for manual cleaning by the staff, which shortens the waiting time between the forging of two forgings and improves the overall forging efficiency of multiple forgings.

[0026] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 , a forging equipment for large-scale die forging special die forgings, based on Example 2, further, the scraper 704 includes a plurality of slidingly connected plate bodies 7041, a second elastic telescopic rod 7042 is arranged between two adjacent plate bodies 7041, the plate body 7041 of the scraper 704 farthest from the slider 701 is fixedly connected to the first pull rope 504, and the first pull rope 504 is slidingly connected to the slider 701.

[0027] Specifically, when the placement table 301 rotates downward, it drives the arc-shaped rack 6 to mesh with the driven gear 502 for transmission, and the driven gear 502 drives the rotating rod 501 to rotate, and the rotating rod 501 drives the reel 503 to reel in the first pull rope 504. When the first pull rope 504 is reeled in, it applies force to the plate 7041 of the scraper 704 away from the slider 701, and the plates 7041 contract with each other to reduce the length of the scraper 704. After the scraper 704 is reduced to the shortest, the first pull rope 504 applies tension to the slider 701 through the scraper 704, and the slider 701 slides in the frame. 7, the first elastic element 702 is stretched, and the first elastic element 702 is set as a spring. When the scraper 704 moves from the left side of the placement table 301 to the right side, the scraper 704 abuts against the block 901 and the forging, and the scraper 704 is automatically flipped relative to the slider 701 under force. The shortened scraper 704 can quickly pass over the forging and reach the other side of the placement table 301, avoiding the scraper 704 being too long, resulting in the scraper 704 passing over the forging on the placement table 301 for a long time and the frame 7 being designed too long, effectively reducing the size of the forging equipment and improving the forging efficiency.

[0028] Example 4: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig.10 and Fig.11 , a forging equipment for large-scale die forging special die forgings, based on Example 3, further, a movable groove 9 is opened on the placement table 301, a stopper 901 is slidably connected in the movable groove 9, a third elastic telescopic rod 902 is arranged between the inner wall of the movable groove 9 and the stopper 901, and a second pull rope 10 connected to the movable end of the first elastic telescopic rod 4 is arranged at the bottom of the stopper 901.

[0029] Furthermore, a first groove is provided on the inner wall of the movable groove 9, in which a first pneumatic telescopic rod 11 is fixedly installed, a slot 9011 for plugging with the first pneumatic telescopic rod 11 is provided on the block 901, and a second groove is provided on the placement table 301, in which a second pneumatic telescopic rod 12 for movably abutting against the scraper 704 is fixedly installed, and an air guide tube 121 is connected between the second pneumatic telescopic rod 12 and the first pneumatic telescopic rod 11.

[0030] Furthermore, the first pneumatic telescopic rod 11 and the second pneumatic telescopic rod 12 have the same structure, both including a sleeve 111, a piston 112 slidably connected in the sleeve 111, a second elastic element 113 arranged between the piston 112 and the inner wall of the sleeve 111, and a movable rod 114 fixed on the piston 112 and slidably connected to the sleeve 111, the movable rod 114 is provided with an extrusion slope, the movable rod 114 of the first pneumatic telescopic rod 11 is movably plugged into the slot 9011, the movable rod 114 of the second pneumatic telescopic rod 12 is movably abutted against the scraper 704, one end of the air guide tube 121 is connected to the rod-free cavity of the sleeve 111 of the second pneumatic telescopic rod 12, and the other end of the air guide tube 121 is connected to the rod-containing cavity of the sleeve 111 of the first pneumatic telescopic rod 11.

[0031] Specifically, the forging is placed on the placement platform 301, and the placement platform 301 is forced to rotate downward with the first pin shaft 3021 as the center. The stopper 901 can limit the forging sliding down along the inclined placement platform 301 to prevent the forging from sliding up and down and falling on the inclined placement platform 301. When the placement platform 301 is forced to rotate downward, the first elastic telescopic rod 4 contracts and applies tension to the second pull rope 10, so that the stopper 901 contracts into the placement platform 301, and the placement platform 301 is placed horizontally. After that, the top of the stopper 901 and the top surface of the placement table 301 are in the same plane, and the first pneumatic telescopic rod 11 is inserted and limited to the stopper 901. After the forging is forged, the forging is removed from the forging table 3 by a forklift using a clamp. The placement table 301 is no longer subjected to force and resets and moves upward under the elastic force of the first elastic telescopic rod 4. The placement table 301 is tilted again. When the placement table 301 drives the frame 7 to rotate upward, the frame 7 is away from the arc-shaped limit plate 8, and the slider 701 The first elastic element 113 is used as a spring; the second elastic element 113 is used as a spring; the second elastic element 114 ...4 is used as a spring; the second elastic element 114 is used as a spring; the second elastic element 114 is used as a spring; the second elastic element 113 is used as a spring; the second elastic element 114 is used as a spring; the second elastic element 114 is used as a spring; the second elastic element 11

When the first pull rope 504 is reeled in, it applies force to the plate body 7041 of the scraper 704 away from the slider 701, and the plate bodies 7041 contract with each other to reduce the length of the scraper 704. After the scraper 704 is reduced to the shortest, the first pull rope 504 applies tension to the slider 701 through the scraper 704, and the slider 701 slides in the frame 7, and the first elastic element 702 is stretched. When the scraper 704 moves from the left side of the placement table 301 to the right side, the scraper 704 abuts against the block 901 and the forging, and the scraper 704 is automatically flipped relative to the slider 701 under force, and the shortened scraper 704 can quickly pass over the forging and arrive at the other side of the placement table 301.

At this time, the arc-shaped rack 6 is no longer meshed with the driven gear 502, and the rotating rod 501 drives the reel 503 to reset and rotate under the action of the torsion spring, and the reel 503 releases the first pull rope 504, the length of the scraper 704 is restored, and the slider 701 moves back under the pull of the first elastic element 702, until the slider 701 abuts against the arc-shaped limit plate 8, limiting the slider 701 from moving back to the upper side of the placement table 301, and at this time, the top of the stopper 901 is in the same plane as the top surface of the placement table 301, and the first pneumatic telescopic rod 11 is plugged and limited to the stopper 901; S5: Control the hydraulic device 2 to drive the press seat 201 to forge the forging on the forging table 3; S6: After the forging is formed, the forging is removed from the forging table 3 by a forklift using a clamp, the placement table 301 is no longer subjected to force and is reset and moved upward under the elastic force of the first elastic telescopic rod 4, the placement table 301 is tilted again, and when the placement table 301 drives the frame 7 to rotate upward, the frame 7 is away from the arc-shaped limit plate 8, the slider 701 is no longer subjected to force and is reset and moved back under the pull of the first elastic element 702, so that the slider 701 drives the scraper 704 to scrape the oxidized debris remaining on the forging until the scraper 704 moves from the right end of the placement table 301 to the left end, the scraper 704 abuts against the movable rod 114 of the second pneumatic telescopic rod 12, the second pneumatic telescopic rod 12 contracts and introduces the internal air of the second pneumatic telescopic rod 12 into the air cavity of the first pneumatic telescopic rod 11 through the air guide 121, so that the first pneumatic telescopic rod 11 contracts, and the first pneumatic telescopic rod 11 releases the limit of the block 901, and the block 901 is reset to prepare for the limit when other forgings are lowered later; S7: Repeat S1-S6 to achieve continuous forging of other subsequent forgings by the forging equipment.
