Description

Technical Field

[0001] The invention relates to the technical field of petroleum machinery forging, in particular to a forging device for petroleum machinery die forgings. Background Art

[0002] The valve body is the core component of the oil and gas fracturing plunger pump. Since the valve body is subjected to high-pressure alternating loads and high-speed fluid erosion for a long time, in order to improve the overall strength of the valve body, the valve body is usually processed by forging.

[0003] Patent No. CN115229101B discloses an integral forging process and equipment for a valve body of a fracturing pump, including a support column, a base and a hydraulic crane. The top of the support column is fixed with a hydraulic crane by bolts, and a die forging hammer is installed at one end of the hydraulic crane. The two sides of the die forging hammer are in contact with the inner walls of the two sides of the base, and the die forging hammer is slidably connected to the inner wall of the base. The invention drives the entire rotating rod to swing left and right in the groove by a second motor, so that the entire fixed block with a conveying mechanism can move the high-temperature column block to the entire first placement column. At the same time, the entire column block is transformed into a valve body through extrusion and shaping by the upper mold shell on the die forging hammer and the lower mold shell on the first lower fixed plate. The transportation and movement of the entire high-temperature column block between the bases is completed by the arc shell on the sliding rod. Compared with manual clamping and movement of the high-temperature column block, it has a high speed and is relatively safe.

[0004] The above-mentioned device uses a folding rod to clamp the valve body and drive it to move. However, after forging is completed, the forging will remain in the lower mold shell. At this time, the forging has not been completely separated from the lower mold shell. There is a large friction between the forging and the lower mold shell, which affects the clamping efficiency. In addition, some debris will remain in the lower mold shell during the forging process. The above-mentioned device does not clean up the debris after forging, which affects the subsequent forging effect. Summary of the invention

[0018] 4. After the excess material on the outside of the forging is cut off, the moving rod and the moving rack will drive the transmission gear to rotate during the process of the upper pressure plate rising and resetting. The transmission gear will drive the rotating lever to rotate and push out the waste material remaining on the top of the cut die.

[0019] 5. After each forging, when the exhaust pipe passes through the forming die, the inflation pipe discharges the gas from the exhaust pipe to the outside. At this time, the debris remaining in the forming die will be flushed out by the airflow, and the fast-flowing airflow in this process can quickly take away the heat in the forming die, playing a role in cooling down while cleaning the debris.

[0035] During forging, the raw material that has been sintered at a certain temperature for a certain time is placed in the first lower die 106. At this time, the power cylinder 104 drives the upper platen 105 to slide downward along the support guide frame 103, and the first upper die 1051 at the bottom of the upper platen 105 cooperates with the first lower die 106 to perform preliminary forging on the raw material. Then the power cylinder 104 drives the upper platen 105 to rise and reset. In this process, the ejector mechanism lifts the forging that has undergone preliminary forging in the first lower die 106, and then the clamping mechanism clamps the forging that has undergone preliminary forging and drives it to rotate counterclockwise to the second lower die 107.

The forging falls down from the cutting lower die 109 and undergoes subsequent processing. Then the workers take out the cut scraps from the cutting lower die 109 for recycling.

[0036] Embodiment 2: Based on embodiment 1, Figure 3-Figure 7 As shown, the clamping mechanism includes an inclined slide groove 1021, a rotating ring 2, a buffer spring 2001, a one-way bearing 201, a fixed guide frame 202, a moving component and a clamping component. The guide shaft 102 is provided with an inclined slide groove 1021, and the bottom of the inclined slide groove 1021 is a vertical guide groove. The guide shaft 102 is slidably connected with a one-way bearing 201, and a sliding block matching the inclined slide groove 1021 is provided in the one-way bearing 201. During the process of the one-way bearing 201 moving up and down along the guide shaft 102, it will rotate under the action of the inclined slide groove 1021. The guide shaft 102 is slidably connected with a rotating ring 2 outside, and the rotating ring 2 is rotatably connected to the one-way bearing 201. During the rising process of the one-way bearing 201, the rotating ring 2 will be driven to rotate. The fixed guide frame 202 is fixedly connected to the outside of the rotating ring 2, and four fixed guide frames 202 are provided. The moving component is installed in the fixed guide frame 202, and the clamping component is installed in the moving component. The clamping component is used to clamp the forging.

[0037] like Figure 5-Figure 7 As shown, the moving assembly includes a connecting swivel 1055, a sliding frame 203, a clamping spring 2031, a return spring 204, a moving frame 205 and a rotating connecting rod 206. The upper pressing plate 105 is rotatably connected with the connecting swivel 1055, the sliding frame 203 is slidably connected in the fixed guide frame 202, and a return spring 204 is arranged between the sliding frame 203 and the fixed guide frame 202. One end of the return spring 204 is fixed to the fixed guide frame 202, and the other end is fixed to the sliding frame 20 3, a moving frame 205 is slidably connected inside the sliding frame 203, a clamping spring 2031 is provided between the moving frame 205 and the sliding frame 203, the clamping spring 2031 is used to push the moving frame 205 to slide along the sliding frame 203, one end of the clamping spring 2031 is fixed to the moving frame 205, and the other end is fixed to the sliding frame 203, the moving frame 205 is rotatably connected with a rotating link 206, and the other end of the rotating link 206 is rotatably connected to the connecting swivel 1055.

[0038] like Figure 7 As shown, the clamping assembly includes a rotating clamp rod 207 and a swinging link 208. The swinging link 208 is rotatably connected to the movable frame 205, and the sliding frame 203 is rotatably connected to the rotating clamp rod 207. The other end of the swinging link 208 is rotatably connected to the rotating clamp rod 207. When the movable frame 205 slides along the sliding frame 203, the rotating clamp rod 207 is driven to rotate through the swinging link 208, so that the two rotating clamp rods 207 swing outward to open or swing inward to get closer.

[0039] When the upper pressure plate 105 descends, the buffer spring 2001 is in a compressed state. The buffer spring 2001 returns to its original state first, and the other parts of the clamping mechanism descend as a whole with the upper pressure plate 105. The one-way bearing 201 rotates clockwise under the action of the inclined slide groove 1021 first. At this time, the rotating ring 2 will not rotate with the one-way bearing 201. When the buffer spring 2001 returns to its original state, if there are forgings clamped in the two rotating clamping rods 207, the forgings will be placed in the corresponding lower mold. The upper pressure plate 105 continues to descend and will push the moving frame 205 to slide along the sliding frame 203 toward the rotating ring 2 through the rotating connecting rod 206 and compress the clamping spring 2031. In this process, the moving frame 205 will pull the two rotating clamping rods 207 apart through the swing connecting rod 208. The forging between the rotating clamp rod 207 will be loosened, and the moving frame 205 will contact the side of the sliding frame 203 inside the sliding frame 203 close to the rotating ring 2. As the upper pressure plate 105 continues to descend, the upper pressure plate 105 pushes the moving frame 205 and the sliding frame 203 to slide along the fixed guide frame 202 through the rotating connecting rod 206 and compresses the reset spring 204. The rotating clamp rod 207 and the swing connecting rod 208 are moved away from the corresponding forming molds. After the forging is completed, the upper pressure plate 105 rises and resets first. During the rising and resetting process of the upper pressure plate 105, due to the large elastic force of the reset spring 204, the reset spring 204 first recovers and pushes the sliding frame 203 and the moving frame 205 to move along the fixed guide frame 202 in the direction away from the rotating ring 2. When the reset spring 204 recovers, the sliding frame 203 and the moving frame 205 are The two rotating clamping rods 207 on the movable frame 203 move to the two sides of the forging in the corresponding forming mold, and the upper pressure plate 105 continues to rise. The clamping spring 2031 will push the movable frame 205 to slide along the sliding frame 203 in the direction away from the rotating ring 2. At this time, the movable frame 205 will push the two rotating clamping rods 207 to move closer to each other through the swing connecting rod 208 and clamp the forging in the corresponding forming mold. At this time, the clamping spring 2031 returns to its original state. At this time, the upper pressure plate 105 pulls the movable frame 205 up through the rotating connecting rod 206, and the sliding frame 203, the fixed guide frame 202, the rotating ring 2, the one-way bearing 201 and other components rise accordingly. The buffer spring 2001 is compressed, and because the bottom end of the inclined slide groove 1021 is a vertical guide groove, the one-way bearing 2 01 will not be driven to rotate by the inclined slide groove 1021. When the forging in the forming die is taken out, the one-way bearing 201 just slides out of the vertical guide groove at the bottom of the inclined slide groove 1021. As the upper pressure plate 105 continues to rise, the one-way bearing 201 will rotate counterclockwise under the action of the inclined slide groove 1021, and at the same time drive the fixed guide frame 202, the sliding frame 203 and the mobile frame 205 to rotate counterclockwise through the rotating ring 2. The two rotating clamping rods 207 clamp the forging and rotate counterclockwise. When the upper pressure plate 105 rises and resets, the one-way bearing 201 just drives the fixed guide frame 202, the sliding frame 203 and the mobile frame 205 to rotate 90 degrees through the rotating ring 2. The rotating clamping rod 207 also drives the forging to rotate 90 degrees and sends the forging to the next forming die.To automatically transfer forgings and perform continuous forging.

[0040] like Figure 7 , Fig.10 and Fig.11 As shown, the ejection mechanism includes a moving pressure block 2051, a fixed box 4, a guide rod 401, a return spring 402, a wedge block 403, a sliding pressure rod 404, a sliding ejection rod 405 and an ejection spring 406. The moving frame 205 is fixedly connected with the moving pressure block 2051, the processing table 1 is fixedly connected with the fixed box 4, the fixed box 4 is fixedly connected with the guide rod 401, the guide rod 401 is slidably connected with the sliding pressure rod 404, the sliding pressure rod 404 is fixedly connected with the wedge block 403, the moving pressure block 2051 cooperates with the wedge block 403, and the sliding pressure rod 404 is fixedly connected with the sliding pressure rod 404. A return spring 402 is provided between the rod 404 and the fixed box 4, and the return spring 402 is sleeved on the guide rod 401. One end of the return spring 402 is fixed to the fixed box 4, and the other end is fixed to the sliding pressure rod 404. A sliding ejector rod 405 is slidably connected to the processing table 1. One end of the sliding pressure rod 404 close to the sliding ejector rod 405 is tilted downward. An ejector spring 406 is provided between the sliding ejector rod 405 and the processing table 1. One end of the ejector spring 406 is fixed to the sliding ejector rod 405, and the other end is fixed to the processing table 1.

[0041] After the moving frame 205 is lowered to the lowest point, the moving pressing block 2051 will contact the wedge block 403. As the moving frame 205 slides toward the rotating ring 2, the moving pressing block 2051 pushes the sliding pressing rod 404 to slide along the guide rod 401 toward the fixed box 4 through the wedge block 403. The corresponding return spring 402 is compressed. During the movement of the sliding pressing rod 404, the sliding ejector rod 405 is pushed to slide downward along the processing table 1 and compress the ejector spring 406. During the process of forging the forging piece by the forming die, The top of the sliding ejector rod 405 forms a complete surface with the bottom surface of the corresponding forming mold. When the forging is completed, the movable frame 205 moves away from the rotating ring 2. At this time, the return spring 402 pushes the sliding pressure rod 404 to slide and reset along the guide rod 401. Under the push of the ejection spring 406, the sliding ejector rod 405 slides upward along the processing table 1 and resets. During the rising process of the sliding ejector rod 405, the forging in the corresponding forming mold will be lifted up to facilitate the rotating clamping rod 207 to clamp the forging.

Under the action of the clamping spring 210, multiple sliding clamping rods 209 can be dispersed and wrapped outside the forging to clamp forgings of different shapes.

[0043] When the rotating clamp rod 207 moves toward the forging, the sliding clamp rod 209 will first contact the forging, and as the rotating clamp rod 207 continues to rotate, more sliding clamp rods 209 will contact the forging, and multiple sliding clamp rods 209 can slide along the rotating clamp rod 207 according to the shape of the forging and compress the corresponding clamping spring 210, so that the sliding clamp rod 209 in the rotating clamp rod 207 can be arranged according to the shape of the forging to clamp forgings of different shapes.

[0044] like Fig.12 As shown, it also includes a dispensing mechanism for automatically pushing out the cut waste, the dispensing mechanism includes a moving rod 5, a connecting spring 501, a moving rack 502, a transmission gear 503 and a rotating lever 504, the moving rod 5 is slidably connected to the guide rod 401 close to the lower cutting mold 109, a connecting spring 501 is provided between the moving rod 5 and the fixed box 4 body, the connecting spring 501 is sleeved on the moving rod 5, one end of the connecting spring 501 is fixed to the fixed box 4 body, and the other end is fixed to the moving rod 5, the moving rack 502 is fixed to the moving rod 5, the lower cutting mold 109 is rotatably connected to the transmission gear 503, the transmission gear 503 is meshed with the moving rack 502, the transmission gear 503 is coaxially fixed with the rotating lever 504, and the rotating lever 504 slides along the top surface of the lower cutting mold 109.

[0045] When the forging is sent to the cutting lower die 109 in the forming die, the upper pressing plate 105 descends and cuts off the excess material around the forging through the cutting upper die 1054. During the descending process of the upper pressing plate 105, the moving pressing block 2051 on the moving frame 205 drives the moving rod 5 to slide along the guide rod 401 through the wedge block 403, and the connecting spring 501 is also compressed. During the movement of the moving rod 5, the transmission gear 503 is driven to rotate through the moving rack 502, and the rotation of the transmission gear 503 drives the rotating dial The rod 504 swings toward the direction approaching the fixed box 4. When the excess material around the forging is cut off, the forging will fall downward from the cutting die 109, and the excess material will remain on the cutting die 109. At this time, the upper pressure plate 105 rises and resets, and the connecting spring 501 pushes the moving rod 5 and the moving rack 502 to move and reset. The moving rack 502 drives the rotating lever 504 to swing away from the fixed box 4 through the transmission gear 503 to push out the remaining material on the cutting die 109.

[0046] like Figure 8 and Fig. 9 As shown, it also includes a flushing mechanism for cleaning the forming mold and pushing out the waste chips inside it. The flushing mechanism includes a fixed rod 3, an exhaust pipe 301, an inflation pipe 302, a sliding piston 303, an inflation spring 304 and a locking assembly. The fixed rod 3 is fixedly connected to the outside of the rotating ring 2, and the inflation pipe 302 is fixedly connected to the fixed rod 3. The bottom of the inflation pipe 302 is fixedly connected to the exhaust pipe 301, and the inflation pipe 302 is communicated with the exhaust pipe 301. The sliding piston 303 is slidably connected in the inflation pipe 302, and an inflation spring 304 is provided between the sliding piston 303 and the inflation pipe 302. One end of the inflation spring 304 is fixed to the inflation pipe 302, and the other end is fixed to the sliding piston 303. The locking assembly is installed in the connecting swivel 1055, and the locking assembly is used to limit the sliding piston 303.

[0047] like Figure 8 and Fig. 9 As shown, the locking assembly includes a swinging locking rod 305 and a torsion spring 306. The swinging locking rod 305 is rotatably connected inside the connecting ring 1055. The swinging locking rod 305 and the connecting ring 1055 are connected through the torsion spring 306. A locking groove is opened on the sliding piston 303, and the swinging locking rod 305 can be locked in the locking groove on the sliding piston 303.

[0048] When the upper pressure plate 105 is lowered, the connecting ring 1055 is lowered accordingly, and the positions of the inflation tube 302 and the exhaust tube 301 remain unchanged. When the swinging card rod 305 is lowered, it contacts the sliding piston 303. Since the bottom of the swinging card rod 305 is inclined toward the side of the sliding piston 303, the swinging card rod 305 is pushed by the sliding piston 303 and rotates a certain angle, and the torsion spring 306 is deformed by the force. When the upper pressure plate 105 drops to the lowest point, the swinging card rod 305 just drops to the slot on the sliding piston 303. At this time, under the action of the torsion spring 306, the swinging card rod 305 will rotate around the connecting ring 1055 and get stuck in the slot on the sliding piston 303. When the upper pressure plate 105 rises and resets, the swinging card rod 305 will pull the sliding piston 303 to rise upward along the inflation tube 302, so that the inflation tube 302 is filled with air. When the swinging clamping rod 305 is out of contact with the upper pressure plate 105, under the action of the torsion spring 306, the swinging clamping rod 305 rotates around the connecting swivel 1055 to reset.
