Description

Technical Field

[0001] The invention relates to the technical field of forging equipment, and in particular to a high-diameter flange forging equipment and a forming method. Background Art

[0002] High-diameter flange refers to the flange with a higher neck height, which has improved rigidity and load-bearing capacity. Compared with butt-welded flanges, it has a large welding workload, high welding rod consumption, and cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations, but it is more convenient to install on site. High-diameter flanges are widely used in boiler pressure vessels, petroleum, chemical industry, shipbuilding, pharmaceuticals, metallurgy, machinery and stamping elbows.

[0003] In the prior art, when forging high-diameter flange forgings, they need to be pressed down and upset by forging equipment, and then the upset forgings are placed in a die for forging. Whether upsetting or die forging, workers need to use pliers or clamps to shake the forgings back and forth on the side so that the forgings are evenly stressed from all parts of the top to ensure the forging quality. However, the above method is not only cumbersome to operate, but also greatly increases the work intensity and workload of the workers.

[0019] The present invention also discloses a high-diameter flange forging method, which is performed by applying the high-diameter flange forging equipment, and comprises the following steps:

[0020] S1: When placing the forging body in the eccentric groove for forging or placing the forging body in the forging die and then placing it in the eccentric groove for forging, the staff first uses a forklift to place the forging body or the forging die in the eccentric groove. At this time, the press seat is not at the uppermost end of its moving stroke, and the force block does not abut against the press seat. When the forging body is lowered to the eccentric groove, the forging body applies downward pressure to the guide plate, and the guide plate drives the abutment plate to move, so that a placement area suitable for the forging body is formed between the multiple abutment plates;

[0021] As the forging body is lowered, the forging body presses down on the movable support platform, and the movable support platform transmits the force to the support rod, and the support rod contracts under the force until the movable support platform is placed horizontally. At this time, the forging body or the forging die is placed horizontally in the eccentric groove;

[0022] S2: Then the driving motor is controlled to operate, the driving motor drives the driving gear to rotate through the driving shaft, the driving gear meshes with the driven gear for transmission, the driven gear drives the processing seat to rotate through the collar, the processing seat drives the forging body placed thereon to rotate, so that the forging body rotates with the axis of the processing seat as the center of the circle, and when the forging body rotates, each position moves to the lower side of the pressing seat in turn;

[0023] S3: The hydraulic cylinder and the driving motor operate simultaneously, and the hydraulic cylinder drives the pressing seat to continuously reciprocate up and down through the piston rod. When the pressing seat moves down, the pressing seat presses down the forging body moved to the position directly below it for forging. During the forging of the forging body, since the pressing seat presses down on the forging body, there is friction between the forging body and the pressing seat, and the forging body is difficult to move. On the basis of the processing seat maintaining its rotating state without stopping the machine, the first sliding bar in the positioning part moves relative to the sleeve, so that the positioning part in the eccentric groove automatically adapts to the forging body and changes;

[0024] When the forging body is initially forged rather than die forged, the forging body is upset, the diameter of the forging body changes, and the thickened forging body applies thrust to the abutment plate, so that the abutment plate automatically moves and adapts to the forging body with changed diameter;

[0025] When the pressure seat moves upward, the pressure seat no longer presses down on the forging body, and the processing seat is no longer subjected to the downward pressure of the pressure seat. As the piston rod drives the pressure seat to continue to move upward, the hydraulic pipe drives the force block to approach the pressure seat, and the force block abuts against the pressure seat. The force block drives the second piston to slide in the hydraulic pipe, so that the hydraulic oil in the hydraulic pipe is introduced into the rodless cavity of the casing through the oil guide pipe, and then the first piston drives the first slide bar to move relative to the casing, so that the positioning plates at the ends of the multiple first slide bars are reset and moved, until each positioning plate abuts against the forging body whose diameter increases after upsetting, so that the forging body automatically adjusts its position so that it is always placed in the center of the eccentric groove. At this time, the total length of the casing and the first slide bar is shorter than the initial length, and the excess hydraulic oil discharged from the hydraulic pipe is introduced into the pressure relief pipe;

[0026] S4: Repeat S3 to complete the forging work on the forging body. After the forging of the forging body is completed, the staff uses the forklift clamp to take the forging body out of the eccentric groove. The top of the movable support table is no longer stressed. The elastic force of the support rod pushes the movable support table to rotate around the pin shaft connected to the chassis. The movable support table is tilted, and the oxidized waste generated during the forging process falls from the blanking chute along the movable support table.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The high-diameter flange forging equipment and forming method, by placing the forging body in the eccentric groove, makes the processing seat move to the lower side of the pressing seat in sequence during rotation, so as to facilitate uniform forging of various positions of the forging body, and does not require the staff to use pliers or clamps to shake the forging back and forth, thereby reducing the workload and work intensity of the staff, ensuring a safe working environment for forging, and improving the forging efficiency;

[0029] 2. The high-diameter flange forging and forming equipment and forming method provide a positioning part to limit and buffer the forging body during forging. During the forging of the forging body, due to the downward pressure of the pressure seat on the forging body, there is friction between the forging body and the pressure seat, and the forging body is difficult to move. On the basis of the processing seat maintaining its rotation state without stopping, the first slide bar in the positioning part moves relative to the sleeve, so that the positioning part in the eccentric groove automatically adapts to the forging body and changes, so that the driving component drives the forging body to move and the hydraulic cylinder drives the pressure seat to reciprocate up and down forging work at the same time, avoiding the need to stop the driving motor when the hydraulic cylinder presses down on the forging body, realizing the non-stop forging of the forging body, and ensuring the forging work efficiency;

[0030] 3. The high-diameter flange forging and forming equipment and forming method, by arranging a positioning part in the eccentric groove, the positioning part uses the positioning plate to continuously perform self-positioning work on the forging body during forging and forming. When the pressure seat does not press down the forging body for forging, the first slide bar and the sleeve are reset and moved under the action of hydraulic oil until multiple positioning plates are in contact with the forging body, so that the forging body is kept in the center position of the eccentric groove when the processing seat moves, avoiding the situation that when the pressure seat presses down on the forging body for forging, the forging body is not in the center position, and the distance between the first slide bar and the sleeve of a certain positioning part cannot be contracted and changed, which affects the upsetting effect of the forging body, and further affects the forging quality of the forging body;

[0031] 4. The high-diameter flange forging forming equipment and forming method, after the forging of the forging body is completed, the staff uses a forklift clamp to take the forging body out of the eccentric groove, the top of the movable support table is no longer stressed, the elastic force of the support rod pushes the movable support table to rotate around the pin shaft connected to the chassis, the movable support table is tilted, and the oxidized waste generated during the forging process falls from the blanking groove along the movable support table, avoiding the accumulation of oxidized waste in the eccentric groove, affecting the subsequent forging work of the forging body, and at the same time reducing the subsequent cleaning workload of the staff and alleviating the work intensity.

[0046] Example 1: Reference Figure 1 and Figure 3 , a high-diameter flange forging device, comprising a base 1, and also comprising:

[0047] A top seat 2, a fixing rod 101 is arranged between the top seat 2 and the base 1, a hydraulic cylinder 3 is fixedly arranged on the top seat 2, and a piston rod of the hydraulic cylinder 3 is connected to a pressure seat 301;

[0048] A processing seat 4 is rotatably disposed on the base 1. The base 1 is provided with a driving assembly for driving the processing seat 4 to rotate. An eccentric groove 6 for placing a forging body 5 is provided on the processing seat 4.

[0050] Among them, a support rod 8 for supporting the movable support platform 7 is arranged on the processing seat 4.

[0051] Specifically, when the forging body 5 is placed in the eccentric groove 6 for forging or the forging body 5 is placed in the forging die and then placed in the eccentric groove 6 for forging, the staff first uses a forklift to place the forging body 5 or the forging die in the eccentric groove 6, and the movable support platform 7 supports the lowered forging body 5 or the forging die. By placing the forging body 5 in the eccentric groove 6, the driving assembly enables the processing seat 4 to move to the lower side of the pressure seat 301 in turn during rotation, so as to facilitate uniform forging of various positions of the forging body 5. There is no need for the staff to use pliers or clamps to shake the forging back and forth on the side, which reduces the workload and work intensity of the staff, ensures a safe working environment for forging, and improves the forging efficiency of the forging.

[0053] Furthermore, an eccentric groove 6 is provided on the upper plate 404, and a plurality of positioning parts are arranged inside the upper plate 404 along the circumferential direction of the eccentric groove 6. The movable support platform 7 is rotatably connected to the chassis 403 through a pin shaft, and a blanking groove 4031 is provided on the chassis 403, which is coaxially arranged with the chassis 403 and has a diameter larger than that of the movable support platform 7.

[0054] Furthermore, the positioning portion includes a sleeve 9 fixed in the upper plate 404, a first piston 901 is slidably connected in the sleeve 9, a first slide bar 902 is fixed on the first piston 901, a first elastic element 903 (the first elastic element 903 is configured as a spring) is sleeved on the outer side of the first slide bar 902 with two ends respectively connected to the first piston 901 and the inner wall of the sleeve 9, and the end of the first slide bar 902 away from the first piston 901 is connected to a positioning plate 10 that is movably opposed to the forging body 5.

[0055] Furthermore, the positioning plate 10 includes a contact plate 1001 fixedly connected to the first sliding rod 902 and a guide plate 1002 obliquely disposed on the upper side of the contact plate 1001 .

[0056] Furthermore, the positioning portion also includes a support plate 11 fixedly mounted on the top seat 2, and a connecting block 111 is rotatably connected to the support plate 11 through a pin shaft, and elastic telescopic rods 112 are arranged at both ends of the connecting block 111, one of the elastic telescopic rods 112 is connected to the piston rod of the hydraulic cylinder 3, and the other elastic telescopic rod 112 is movably connected to a hydraulic pipe 12 sliding on the support plate 11, and a second piston 121 is slidably connected in the hydraulic pipe 12, and a second sliding rod 122 is fixedly mounted on the second piston 121, and a second elastic element 123 (the second elastic element 123 is set as a spring) is sleeved on the second sliding rod 122, whose two ends are respectively connected to the second piston 121 and the inner wall of the hydraulic pipe 12, and the end of the second sliding rod 122 away from the second piston 121 is connected to a force block 124 movably resisting the pressure seat 301.

[0057] Furthermore, an oil guide pipe 13 is connected between the rodless cavity of the hydraulic tube 12 and the rodless cavity of the sleeve 9. The rodless cavity of the hydraulic tube 12, the rodless cavity of the sleeve 9 and the oil guide pipe 13 are filled with hydraulic oil. A pressure relief pipe 15 is fixedly provided on the sleeve 9. A third piston 151 is slidably connected in the pressure relief pipe 15. A fourth elastic element 152 is arranged between the third piston 151 and the inner wall of the pressure relief pipe 15.

[0058] Specifically, when the forging body 5 is placed in the eccentric groove 6 for forging or the forging body 5 is placed in the forging die and then placed in the eccentric groove 6 for forging, the staff first uses a forklift to place the forging body 5 or the forging die in the eccentric groove 6. At this time, the pressure seat 301 is not at the uppermost end of its moving stroke, and the force block 124 is not in contact with the pressure seat 301. When the forging body 5 is lowered to the eccentric groove 6, the forging body 5 applies downward pressure to the guide plate 1002, and the guide plate 1002 drives the abutting plate 1001 to move, so that a placement area suitable for the forging body 5 is formed between the multiple abutting plates 1001, and the movable support platform 7 supports the forging body 5.

[0059] Then, the driving assembly is controlled to drive the processing seat 4 to rotate, and the processing seat 4 drives the forging body 5 placed thereon to rotate, so that the forging body 5 rotates with the axis of the processing seat 4 as the center of the circle, and when the forging body 5 rotates, each position moves to the lower side of the pressing seat 301 in sequence;

[0060] The hydraulic cylinder 3 and the driving motor 141 operate simultaneously. The hydraulic cylinder 3 drives the pressing seat 301 to continuously reciprocate up and down through the piston rod. When the pressing seat 301 moves down, the pressing seat 301 presses down the forging body 5 moved to the position directly below it for forging. During the forging of the forging body 5, due to the downward pressure of the pressing seat 301 on the forging body 5, there is friction between the forging body 5 and the pressing seat 301, and the forging body 5 is difficult to move. On the basis of the processing seat 4 maintaining its rotation state without stopping, the first slide bar 902 in the positioning part moves relative to the sleeve 9, so that the positioning part in the eccentric groove 6 automatically adapts to the forging body 5 and changes, so that the driving component drives the forging body 5 to move and the hydraulic cylinder 3 drives the pressing seat 301 to reciprocate up and down forging work at the same time, avoiding the need to stop the driving component when the hydraulic cylinder 3 presses down the forging body 5, realizing the non-stop forging of the forging body 5, and ensuring the forging efficiency;

[0061] When the forging body 5 is initially forged rather than die forged, the forging body 5 is upset, and the diameter of the forging body 5 changes. The thickened forging body 5 applies a thrust to the abutment plate 1001, so that the abutment plate 1001 automatically moves and adjusts to adapt to the forging body 5 with a changed diameter.

[0062] When the pressure seat 301 moves upward, the pressure seat 301 no longer presses down on the forging body 5, and the processing seat 4 is no longer subjected to the downward pressure of the pressure seat 301. As the piston rod drives the pressure seat 301 to continue to move upward, the hydraulic pipe 12 drives the force block 124 to approach the pressure seat 301, and the force block 124 abuts against the pressure seat 301. The force block 124 drives the second piston 121 to slide in the hydraulic pipe 12, so that the hydraulic oil in the hydraulic pipe 12 is introduced into the rodless cavity of the sleeve 9 through the oil guide pipe 13, and then the first piston 901 drives the first slide bar 902 to move relative to the sleeve 9, so that the positioning plates at the ends of the multiple first slide bars 902 are 10 are reset and moved until each positioning plate 10 abuts against the forging body 5 whose diameter becomes larger after upsetting, so that the forging body 5 automatically adjusts its position so that it is always placed in the center of the eccentric groove 6, to avoid the situation that when the pressure seat 301 presses down on the forging body 5 for forging, the forging body 5 is not in the center position, and the distance between the first slide bar 902 and the sleeve 9 of a certain positioning part cannot be contracted and changed during the upsetting forging, which affects the upsetting effect of the forging body 5. At this time, the total length of the sleeve 9 and the first slide bar 902 is shorter than the initial length, and the excess hydraulic oil discharged from the hydraulic pipe 12 is introduced into the pressure relief pipe 15.

[0063] Example 3: Reference Figure 1 , Figure 3 , Figure 4 and Figure 7, a high-diameter flange forging equipment, based on Example 2, further, the driving component includes a side plate 14 fixedly mounted on the base 1, a driving motor 141 is fixedly mounted on the side plate 14, the output shaft of the driving motor 141 passes through the side plate 14 and is connected to a driving gear 142, a driven gear 143 meshing with the driving gear 142 is rotatably connected in the base 1, and a ring 144 is fixedly mounted on the outer side of the rotating plate 401 on the driven gear 143.

[0064] Specifically, the driving motor 141 is controlled to operate, the driving motor 141 drives the driving gear 142 to rotate through the driving shaft, the driving gear 142 is meshed with the driven gear 143 for transmission, the driven gear 143 drives the processing seat 4 to rotate through the collar 144, the processing seat 4 drives the forging body 5 placed thereon to rotate, so that the forging body 5 rotates with the axis of the processing seat 4 as the center of the circle, and when the forging body 5 rotates, each position moves to the lower side of the pressing seat 301 in sequence.

[0065] Example 4: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.11 , a high-diameter flange forging equipment, based on Example 3, further, the support rod 8 includes a rod body 801 fixedly connected to the rotating plate 401, a push rod 802 is slidably connected inside the rod body 801, a third elastic element 803 is arranged between the rod body 801 and the push rod 802 (the third elastic element 803 is arranged as a spring), and a ball 804 is arranged at one end of the push rod 802 away from the third elastic element 803, which is movably opposed to the movable support platform 7.

[0066] Specifically, when the forging body 5 is lowered, the forging body 5 presses down on the movable support platform 7, and the movable support platform 7 transmits the force to the support rod 8. The support rod 8 is forced to shrink until the movable support platform 7 is placed horizontally. At this time, the forging body 5 or the forging die is placed horizontally in the eccentric groove 6. After the forging of the forging body 5 is completed, the staff uses a forklift clamp to take the forging body 5 out of the eccentric groove 6. The top of the movable support platform 7 is no longer subjected to force. The elastic force of the support rod 8 pushes the movable support platform 7 to rotate around the pin shaft connected to the chassis 403. The movable support platform 7 is tilted, and the oxidized waste generated during the forging process falls from the blanking groove 4031 along the movable support platform 7, avoiding the accumulation of oxidized waste in the eccentric groove 6, affecting the subsequent forging work of the forging body 5, and at the same time reducing the subsequent cleaning workload of the staff and alleviating the work intensity; it should be noted that a ball 804 is arranged at the end of the push rod 802 to contact with the movable support platform 7, which effectively avoids the wear caused by the sliding of the push rod 802 and the movable support platform 7, thereby ensuring the service life of the equipment.

[0067] The present invention also discloses a high-diameter flange forging method, which is performed by using a high-diameter flange forging device, and includes the following steps:

[0068] S1: When placing the forging body 5 in the eccentric groove 6 for forging or placing the forging body 5 in the forging die and then placing it in the eccentric groove 6 for forging, the staff first uses a forklift to place the forging body 5 or the forging die in the eccentric groove 6. At this time, the pressure seat 301 is not at the uppermost end of its moving stroke, and the force block 124 is not in contact with the pressure seat 301. When the forging body 5 is lowered to the eccentric groove 6, the forging body 5 applies downward pressure to the guide plate 1002, and the guide plate 1002 drives the abutting plate 1001 to move, so that a placement area suitable for the forging body 5 is formed between the multiple abutting plates 1001;

[0069] As the forging body 5 is lowered, the forging body 5 presses down the movable support platform 7, and the movable support platform 7 transmits the force to the support rod 8, and the support rod 8 is forced to shrink until the movable support platform 7 is placed horizontally. At this time, the forging body 5 or the forging die is placed horizontally in the eccentric groove 6;

[0070] S2: Then, the driving motor 141 is controlled to operate, and the driving motor 141 drives the driving gear 142 to rotate through the driving shaft, and the driving gear 142 is meshed with the driven gear 143 for transmission, and the driven gear 143 drives the processing seat 4 to rotate through the collar 144, and the processing seat 4 drives the forging body 5 placed thereon to rotate, so that the forging body 5 rotates with the axis of the processing seat 4 as the center of the circle, and when the forging body 5 rotates, each position moves to the lower side of the pressing seat 301 in sequence;

[0071] S3: The hydraulic cylinder 3 and the driving motor 141 operate simultaneously. The hydraulic cylinder 3 drives the pressing seat 301 to continuously reciprocate up and down through the piston rod. When the pressing seat 301 moves downward, the pressing seat 301 presses down the forging body 5 moved to the position directly below it for forging. During the forging of the forging body 5, since the pressing seat 301 presses down the forging body 5, there is friction between the forging body 5 and the pressing seat 301, and it is difficult for the forging body 5 to move. On the basis of the processing seat 4 maintaining its rotating state without stopping the machine, the first sliding bar 902 in the positioning part moves relative to the sleeve 9, so that the positioning part in the eccentric groove 6 automatically adapts to the forging body 5 and changes;

[0072] When the forging body 5 is initially forged instead of die forged, the forging body 5 is upset, and the diameter of the forging body 5 changes. The thickened forging body 5 applies a thrust to the abutment plate 1001, so that the abutment plate 1001 automatically moves and adapts to the forging body 5 with a changed diameter.

[0073] When the pressure seat 301 moves upward, the pressure seat 301 no longer presses down on the forging body 5, and the processing seat 4 is no longer subjected to the downward pressure of the pressure seat 301. As the piston rod drives the pressure seat 301 to continue to move upward, the hydraulic pipe 12 drives the force block 124 to approach the pressure seat 301, and the force block 124 abuts against the pressure seat 301. The force block 124 drives the second piston 121 to slide in the hydraulic pipe 12, so that the hydraulic oil in the hydraulic pipe 12 is introduced into the rodless cavity of the sleeve 9 through the oil guide pipe 13, and then the first piston 901 drives the first slide bar 902 to move relative to the sleeve 9, so that the positioning plates 10 at the ends of the multiple first slide bars 902 are reset and moved until each positioning plate 10 abuts against the forging body 5 whose diameter increases after upsetting, so that the forging body 5 automatically adjusts its position so that it is always placed in the center of the eccentric groove 6. At this time, the total length of the sleeve 9 and the first slide bar 902 is shorter than the initial length, and the excess hydraulic oil discharged from the hydraulic pipe 12 is introduced into the pressure relief pipe 15;

[0074] S4: Repeat S3 to complete the forging work on the forging body 5. After the forging of the forging body 5 is completed, the staff uses a forklift clamp to take the forging body 5 out of the eccentric groove 6. The top of the movable support platform 7 is no longer under force. The elastic force of the support rod 8 pushes the movable support platform 7 to rotate around the pin shaft connected to the chassis 403. The movable support platform 7 is placed at an angle, and the oxidized waste generated during the forging process falls from the blanking groove 4031 along the movable support platform 7.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

At this time, the pressure seat (301) is not at the uppermost end of its moving stroke, and the force block (124) is not in contact with the pressure seat (301). When the forging body (5) is lowered into the eccentric groove (6), the forging body (5) applies downward pressure to the guide plate (1002), and the guide plate (1002) drives the abutting plate (1001) to move, so that a placement area suitable for the forging body (5) is formed between the plurality of abutting plates (1001); As the forging body (5) is lowered, the forging body (5) presses down on the movable support platform (7), and the movable support platform (7) transmits the force to the support rod (8), and the support rod (8) contracts under the force until the movable support platform (7) is placed horizontally. At this time, the forging body (5) or the forging die is placed horizontally in the eccentric groove (6); S2: Then, the driving motor (141) is controlled to operate, and the driving motor (141) drives the driving gear (142) to rotate via the driving shaft, and the driving gear (142) is meshed with the driven gear (143) for transmission, and the driven gear (143) drives the processing seat (4) to rotate via the collar (144), and the processing seat (4) drives the forging body (5) placed thereon to rotate, so that the forging body (5) rotates with the axis of the processing seat (4) as the center of the circle, and when the forging body (5) rotates, each position moves to the lower side of the pressing seat (301) in sequence; S3: The hydraulic cylinder (3) and the driving motor (141) operate simultaneously, and the hydraulic cylinder (3) drives the pressure seat (301) to continuously reciprocate up and down through the piston rod. When the pressure seat (301) moves downward, the pressure seat (301) presses down the forging body (5) that has moved to the position directly below it for forging. During the forging of the forging body (5), due to the downward pressure of the pressure seat (301) on the forging body (5), there is friction between the forging body (5) and the pressure seat (301), and the forging body (5) is difficult to move. On the basis of the processing seat (4) maintaining its rotation state without stopping the machine, the first slide bar (902) in the positioning part moves relative to the sleeve (9), so that the positioning part in the eccentric groove (6) automatically adapts to the forging body (5) and changes; When the forging body (5) is initially forged rather than die forged, the forging body (5) is upset, the diameter of the forging body (5) changes, and the upset forging body (5) applies a thrust to the abutment plate (1001), so that the abutment plate (1001) automatically moves and adapts to the forging body (5) with a changed diameter; When the pressure seat (301) moves upward, the pressure seat (301) no longer presses down on the forging body (5), and the processing seat (4) is no longer subjected to the downward pressure of the pressure seat (301). As the piston rod drives the pressure seat (301) to continue to move upward, the hydraulic pipe (12) drives the force block (124) to approach the pressure seat (301), the force block (124) abuts against the pressure seat (301), and the force block (124) drives the second piston (121) to slide in the hydraulic pipe (12), so that the hydraulic oil in the hydraulic pipe (12) is introduced into the sleeve (9) through the oil guide pipe (13). The first piston (901) drives the first slide bar (902) to move relative to the sleeve (9), so that the positioning plates (10) at the ends of the plurality of first slide bars (902) are reset and moved until each positioning plate (10) abuts against the forging body (5) whose diameter increases after upsetting, so that the forging body (5) automatically adjusts its position so that it is always located at the center of the eccentric groove (6). At this time, the total length of the sleeve (9) and the first slide bar (902) is shorter than the initial length, and the excess hydraulic oil discharged from the hydraulic pipe (12) is introduced into the pressure relief pipe (15); S4: Repeat S3 to complete the forging of the forging body (5). After the forging of the forging body (5) is completed, the staff uses a forklift clamp to take the forging body (5) out of the eccentric groove (6).
