Description
Technical Field
[0001] This invention relates to the field of valve processing equipment technology, specifically to an auxiliary processing device for forging valve blanks and its usage method. Background Technology
[0002] Valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. In the production and manufacturing process of valves, raw materials are generally processed into blanks through a series of processes such as cutting, calcining, and forging. The blanks are then subjected to roughing and finishing processes to obtain reliable valve components. During the forging process of valve blanks, a variety of auxiliary processing devices are usually used to ensure the quality and precision of the forging.
[0003] In the process of forging valve blanks, in order to ensure the quality of the blanks, it is usually necessary to frequently rotate the position of the blanks and clamp and fix them. However, when the blanks are forged, the outer diameter of the blanks usually increases. After the blanks are fixed, the plastic flow of the metal may be restricted, making it difficult for the metal to be evenly distributed, thus affecting the forming quality of the blanks. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides an auxiliary processing device for forging valve blanks, including a forging table, a motor fixedly connected to the side wall of the forging table, a swing rod rotatably connected to the inner wall of the forging table, a forging block slidably connected to the inner wall of the forging table, and a rocker arm rotatably connected to the outer wall of the swing rod.
[0005] The adjustment mechanism includes a blank, a gear ring for adjusting the position of the blank, a servo motor, a gear rod, and a limiting component for limiting the clamping of the blank;
[0006] The blank is placed on top of the forging table. A gear ring is rotatably connected to the outer wall of the forging table, and a servo motor is fixedly connected to the side wall of the forging table. A gear rod is fixedly connected to the top output end of the servo motor, and the outer wall of the gear rod meshes with the outer wall of the gear ring. The output end of the motor is fixedly connected to the side wall of the swing rod, and the inner wall of the swing rod is rotatably connected to the top of the forging block. The operator places the heated blank on top of the forging table, then starts the servo motor to drive the gear rod to rotate, which in turn drives the gear ring to rotate. The fixed frame is rotated, causing the ball bearings at the top of the spring pressure plate to contact the inclined surface of the inclined ring. This compresses the spring pressure plate, allowing it to accumulate rebound force. The spring pressure plate then descends, compressing the gas inside the fixed frame. The compressed gas increases in pressure until it can push the piston rod, causing the spring clamping blocks to move and contact the workpiece. This pushes the workpiece forward, and through the coordinated movement of the three spring clamping blocks, the workpiece is positioned at the center of the forging table. The ball bearings continue moving until they reach the bottom of the inclined ring. At this point, the spring pressure plate contacts the piston rod, causing it to descend. The piston rod compresses the hydraulic oil in the oil supply pipe, which in turn pushes the piston rod to move. The piston rod then pushes the spring clamping block to move again, accumulating rebound force and applying greater clamping force to the workpiece. At this point, the gear ring rotates, and through the fixed frame and spring clamping block, it drives the workpiece to rotate, thereby adjusting the forging position of the workpiece until the ball bearings rotate to the position of the arc-shaped groove. At this point, the rebound force of the spring pressure plate is released, causing the spring pressure plate to rise and separate from the piston rod, simultaneously reducing the pressure on the gas. The rebound force of the spring clamping block is also released. Pushing the piston rod back to its original position reduces the pressure on the blank. Then, the motor can be started to rotate, driving the swing rod to rotate. This causes the swing rod to push the forging block down, forging the blank. The gear ring continues to rotate, moving the fixed frame and allowing the ball bearings to move back to the bottom of the inclined ring, thus rotating the blank until the ball bearings move back to the position of the arc groove. This process is repeated to smoothly rotate the blank. It also reduces the clamping force on the blank during forging, effectively preventing excessive clamping force from affecting the blank's dimensions.
[0007] Preferably, the limiting component includes three fixed frames fixedly connected to the top of the gear ring, spring pressure plates slidably connected to the inner walls of the three fixed frames, ball bearings rotatably connected to the top of the three spring pressure plates, and a beveled ring fixedly connected to the outer wall of the forging table, with twelve arc-shaped grooves at the bottom of the beveled ring.
[0008] Each of the three fixed frames has an air collection cylinder fixedly connected to its inner wall.
[0009] Preferably, the limiting assembly also includes three spring clamping blocks disposed on the top of the forging table, piston push rods are slidably connected to the inner walls of the three gas collecting cylinders, the outer walls of the three spring clamping blocks are slidably connected to the inner walls of the three piston push rods, oil supply pipes are fixedly connected to the inner walls of the three piston push rods, and hydraulic oil is disposed on the inner walls of the three oil supply pipes.
[0010] Preferably, the limiting assembly further includes a piston rod 1 slidably connected to the inner wall of the oil pipe, a piston rod 2 slidably connected to the inner wall of each of the three oil pipes, a side wall of each of the three piston rods 2 being fixedly connected to the side wall of each of the three spring clamping blocks, and a separation assembly provided at the bottom of the inclined ring.
[0011] Preferably, the separation component includes an air collection frame fixedly connected to the side wall of the fixed frame, a spring pressing plate slidably connected to the inner wall of each of the three air collection frames, two jet pipes slidably connected to the inner wall of each of the three air collection frames, and five air holes opened on the inner wall of each of the three air collection frames.
[0012] Preferably, the separation assembly further includes two blocking rods fixedly connected to the inner wall of the gas collecting frame, the outer walls of the six blocking rods are slidably connected to the inner walls of the six jet pipes, and four fixing blocks are fixedly connected to the outer walls of the three piston push rods. A pushing assembly is provided on the top of the forging table. When the spring pressure plate moves from the arc-shaped groove to the bottom of the inclined ring, the spring pressure plate descends and pushes the spring pressing plate down. When the spring pressing plate moves to cover the air hole, the spring pressing plate will squeeze the gas in the gas collecting frame. At this time, the squeezed gas will be blocked by the blocking rods, so the gas pressure will increase. At the same time, when the piston push rod moves, it will drive the fixing block to move, and the fixing block will drive the jet pipe to move, so that the jet pipe is close to the blank.
[0013] Preferably, the pushing assembly includes six spring rotating blocks disposed on the top of the forging table, two sliding blocks are slidably connected to the side walls of the three fixed frames, the outer walls of the six spring rotating blocks are rotatably connected to the inner walls of the six sliding blocks, and the side walls of the six spring rotating blocks are fixedly connected to the side walls of the six sliding blocks by arc springs.
[0014] Each of the three fixed frames has two fixed brackets fixedly connected to its side wall, and each of the six fixed brackets has a push rod slidably connected to its inner wall.
[0015] Preferably, the pushing assembly further includes two spring return rods fixedly connected to the side wall of the fixed frame, and connecting rods are rotatably connected to the side walls of the six pushing rods. The six connecting rods are in pairs, and the bottom of the three spring pressing plates are rotatably connected to the inner walls of the three sets of connecting rods.
[0016] The outer walls of the six spring return rods are slidably connected to the inner walls of the six sliding blocks. The bottom of each of the six spring rotating blocks is fixedly connected to a cleaning steel brush. The top of the spring rotating block is equipped with an air jet assembly. When the spring pressing plate descends, it pushes the connecting rod to rotate, causing the connecting rod to push the push rod towards the spring rotating block. At the same time, the spring pressing plate pushes the spring rotating block to descend, causing the sliding block to descend as well. This causes the spring return rod to be compressed and accumulate rebound force until the cleaning steel brush at the bottom of the spring rotating block contacts the top of the forging table. At this point, the push rod will contact the spring rotating block, thereby pushing the spring rotating block to rotate. This causes the spring rotating block and the cleaning steel brush to move away from the spring clamping block, thus moving the oxide around the spring clamping block.
[0017] Preferably, the jet assembly includes a connecting frame fixedly connected to the top of the spring rotating block, a spring reset plate slidably connected to the inner wall of each of the six connecting frames, a fixing plate fixedly connected to the side wall of each of the six sliding blocks, and an arc-shaped guide plate fixedly connected to the side wall of each of the six connecting frames.
[0018] Each of the six spring reset plates has a Z-shaped plate fixedly connected to its side wall. The side walls of the six Z-shaped plates are slidably connected to the inner walls of the six arc-shaped guide plates. When the spring rotating block rotates, it will drive the connecting frame to move. As the connecting frame continues to move, the spring reset plate will come into contact with the fixed plate, causing the spring reset plate to be squeezed. The spring reset plate will then move towards the arc-shaped guide plate, squeezing the gas in the connecting frame. When the spring reset plate drives the Z-shaped plate into the arc-shaped guide plate, the squeezed gas will be blocked by the Z-shaped plate.
[0019] A method for using an auxiliary machining device for forging valve blanks includes the following steps:
[0020] S1: Workpiece placement: Place the heated blank on top of the forging table;
[0021] S2: Position Adjustment: Start the servo motor to drive the gear rod to rotate. The gear rod will drive the gear ring to rotate, causing the fixed frame to rotate. This will cause the ball bearings on the top of the spring pressure plate to contact the inclined surface of the inclined ring, causing the spring pressure plate to be compressed and accumulate rebound force. The spring pressure plate will then descend to compress the gas in the fixed frame. The gas pressure will increase due to compression until the high-pressure gas can push the piston rod to move.
[0022] The present invention has the following beneficial effects:
[0023] (1) When using this invention, the operator places the heated blank on the top of the forging table, then starts the servo motor to drive the gear rod to rotate. The gear rod will drive the gear ring to rotate, causing the fixed frame to rotate. This allows the ball bearings on the top of the spring pressure plate to contact the inclined surface of the inclined ring, causing the spring pressure plate to be compressed and accumulate rebound force. The spring pressure plate will then descend and compress the gas in the fixed frame. The gas pressure will increase due to compression until the high-pressure gas can push the piston rod to move, causing the spring clamping block to move and contact the blank, pushing the blank to move. Through the coordinated push of the three spring clamping blocks, the blank is placed at the center of the forging table until the ball bearings move to the bottom of the inclined ring. At this time, the spring pressure plate will contact the first piston rod, compressing the first piston rod to descend. The first piston rod will compress the hydraulic oil in the oil pipe, and the hydraulic oil will push the second piston rod to move. The second piston rod will push the spring clamping block to move again, accumulating rebound force and applying pressure to the blank. With greater clamping force, the gear ring rotates, and through the fixed frame and spring clamping block, it can drive the blank to rotate, thereby adjusting the forging position of the blank until the ball rotates to the position of the arc groove. At this time, the spring pressure plate will release its rebound force, causing the spring pressure plate to rise and separate from the piston rod, while reducing the pressure on the gas. The spring clamping block will release its rebound force, pushing the piston rod back to its original position, thereby reducing the pressure on the blank. Then, the motor can be started to rotate, driving the swing rod to rotate, causing the swing rod to push the forging block down to forge the blank. The gear ring continues to rotate, causing the fixed frame to move, allowing the ball to move back to the bottom of the inclined ring, thereby driving the blank to rotate until the ball moves back to the position of the arc groove. This process repeats, which can smoothly drive the blank to rotate. It can also reduce the clamping force on the blank when it is being forged, effectively preventing the clamping force on the blank from being too large and affecting the size of the blank.
[0024] (2) When the spring pressure plate moves from the arc-shaped groove to the bottom of the inclined ring, the spring pressure plate descends and pushes the spring pressing plate down. When the spring pressing plate moves and covers the air hole, the spring pressing plate will squeeze the gas in the gas collection frame. At this time, the squeezed gas will be blocked by the blocking rod, so the gas pressure will increase. At the same time, when the piston push rod moves, it will drive the fixed block to move. The fixed block will drive the jet pipe to move, so that the jet pipe is close to the blank until the jet pipe separates from the blocking rod. The gas will enter the jet pipe, and the high-pressure gas will be sprayed out through the jet pipe to the area around the spring clamping block to clean the oxide around the spring clamping block. This effectively prevents the oxide that falls off the blank during forging from accumulating around the blank. When the spring clamping block moves, it may push the oxide to adhere to the surface of the blank, affecting the forging quality.
[0025] (3) When the spring pressing plate descends, the present invention will push the connecting rod to rotate, so that the connecting rod pushes the push rod to move towards the spring rotating block. At the same time, the spring pressing plate will push the spring rotating block to descend, causing the sliding block to descend, so that the spring reset rod is squeezed and accumulates rebound force until the cleaning steel brush at the bottom of the spring rotating block contacts the top of the forging table. At this time, the push rod will contact the spring rotating block, thereby pushing the spring rotating block to rotate, so that the spring rotating block and the cleaning steel brush are away from the spring clamping block, and pushing the oxide around the spring clamping block to move. This effectively prevents the oxide around the spring clamping block from being too much, and the high-pressure gas makes it difficult to push the oxide to move a greater distance, affecting the separation of the oxide from the spring clamping block.
[0026] (4) When the spring rotating block rotates, it will drive the connecting frame to move. As the connecting frame continues to move, the spring reset plate will come into contact with the fixed plate, causing the spring reset plate to be squeezed. The spring reset plate will then move towards the arc-shaped guide plate, squeezing the gas in the connecting frame. When the spring reset plate drives the Z-shaped plate into the arc-shaped guide plate, the squeezed gas will be blocked by the Z-shaped plate, so the gas pressure will increase until the bottom of the Z-shaped plate moves to the arc surface inside the arc-shaped guide plate. At this time, a gap will be leaked between the arc-shaped guide plate and the Z-shaped plate, and the high-pressure gas will spray out from the arc-shaped guide plate through the gap onto the cleaning steel brush, cleaning the oxides attached to the cleaning steel brush. This effectively prevents the cleaning steel brush from accumulating too much oxide, which may fall onto the top of the forging table during reuse, causing secondary pollution.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Example 1, please refer to Figure 1 - Figure 6The present invention is an auxiliary processing device for forging valve blanks, including a forging table 1, a motor 11 fixedly connected to the side wall of the forging table 1, a swing rod 12 rotatably connected to the inner wall of the forging table 1, a forging block 13 slidably connected to the inner wall of the forging table 1, and a rocker arm 14 rotatably connected to the outer wall of the swing rod 12.
[0043] Adjustment mechanism 2 includes blank 24, gear ring 21 for adjusting the position of blank 24, servo motor 22, gear rod 23, and limiting component 3 for limiting the clamping of blank 24;
[0044] The bottom of the blank 24 is placed on top of the forging table 1. A gear ring 21 is rotatably connected to the outer wall of the forging table 1. A servo motor 22 is fixedly connected to the side wall of the forging table 1. A gear rod 23 is fixedly connected to the top output end of the servo motor 22. The outer wall of the gear rod 23 meshes with the outer wall of the gear ring 21. The output end of the motor 11 is fixedly connected to the side wall of the swing rod 12. The inner wall of the swing rod 14 is rotatably connected to the top of the forging block 13. The operator places the heated blank 24 on top of the forging table 1, and then starts the servo motor 22 to drive the gear rod 23 to rotate. The gear rod 23 will drive the gear ring 21 to rotate, causing the fixed frame to rotate. Rotating the spring plate 31 causes the ball bearing 321 at the top of the spring plate 32 to contact the inclined surface of the inclined ring 33, compressing the spring plate 32 and accumulating rebound force. The spring plate 32 then descends, compressing the gas inside the fixed frame 31. The compressed gas increases in pressure until it can push the piston rod 341, causing the spring clamping block 35 to move and contact the blank 24, pushing the blank 24 to move. Through the coordinated pushing of the three spring clamping blocks 35, the blank 24 is positioned at the center of the forging table 1 until the ball bearing 321 moves to the bottom of the inclined ring 33. At this point, the spring plate 32 contacts the piston rod 361, compressing it to descend. The piston rod 361 compresses the hydraulic oil in the oil pipe 36, which in turn pushes the piston rod 362 to move. The piston rod 362 then pushes the spring clamping block 35 to move again, accumulating rebound force and applying a greater clamping force to the blank 24. At this time, the gear ring 21 rotates, and through the fixed frame 31 and the spring clamping block 35, it can drive the blank 24 to rotate, thereby adjusting the forging position of the blank 24 until the ball bearing 321 rotates to the position of the arc-shaped groove 331. At this time, the rebound force of the spring pressure plate 32 is released, causing the spring pressure plate 32 to rise and separate from the piston rod 361, while reducing the pressure on the gas. The rebound force of the spring clamping block 35 is also released, pushing... Piston rod 262 returns to its original position, thereby reducing the squeezing pressure on blank 24. Then, motor 11 can be started to rotate, driving swing rod 12 to rotate, causing swing rod 14 to push forging block 13 down to forge blank 24. Gear ring 21 continues to rotate, causing fixed frame 31 to move, allowing ball 321 to move back to the bottom of inclined ring 33, thereby driving blank 24 to rotate until ball 321 moves back to the position of arc groove 331. This process is repeated, which can smoothly drive blank 24 to rotate. It can also reduce the clamping force on blank 24 when blank 24 is being forged, effectively preventing excessive clamping force on blank 24 and affecting the size of blank 24.
[0045] Example 2, please refer to Figure 6 - Figure 11The present invention is an auxiliary processing device for forging valve blanks. Based on the first embodiment, the limiting component 3 includes three fixed frames 31 fixedly connected to the top of the gear ring 21. Spring pressure plates 32 are slidably connected to the inner walls of the three fixed frames 31. Ball bearings 321 are rotatably connected to the top of the three spring pressure plates 32. An inclined ring 33 is fixedly connected to the outer wall of the forging table 1. Twelve arc-shaped grooves 331 are opened at the bottom of the inclined ring 33.
[0046] Among them, air collecting cylinders 34 are fixedly connected to the inner walls of the three fixed frames 31.
[0047] The limiting assembly 3 also includes three spring clamping blocks 35 set on the top of the forging table 1. Piston push rods 341 are slidably connected to the inner walls of the three gas collecting cylinders 34. The outer walls of the three spring clamping blocks 35 are slidably connected to the inner walls of the three piston push rods 341. Oil supply pipes 36 are fixedly connected to the inner walls of the three piston push rods 341. Hydraulic oil is provided on the inner walls of the three oil supply pipes 36.
[0048] The limiting component 3 also includes a piston rod 361 that is slidably connected to the inner wall of the oil pipe 36, a piston rod 362 that is slidably connected to the inner wall of each of the three oil pipes 36, and the side walls of the three piston rods 362 that are fixedly connected to the side walls of the three spring clamping blocks 35. A separation component 4 is provided at the bottom of the inclined ring 33.
[0049] The separation component 4 includes an air collection frame 41 fixedly connected to the side wall of the fixed frame 31. Spring pressing plates 42 are slidably connected to the inner walls of the three air collection frames 41. Two jet pipes 43 are slidably connected to the inner walls of the three air collection frames 41. Five air holes 411 are opened on the inner walls of the three air collection frames 41.
[0050] The separation assembly 4 also includes two blocking rods 45 fixedly connected to the inner wall of the gas collection frame 41. The outer walls of the six blocking rods 45 are slidably connected to the inner walls of the six jet pipes 43. The outer walls of the three piston push rods 341 are fixedly connected to four fixing blocks 44. The top of the forging table 1 is provided with a pushing assembly 5. When the spring pressure plate 32 moves again from the arc groove 331 to the bottom of the inclined ring 33, the spring pressure plate 32 descends and pushes the spring pressing plate 42 down. When the spring pressing plate 42 moves to cover the air hole 411, the spring pressing plate 42 will squeeze the gas in the gas collection frame 41. At this time, the squeezed gas will be blocked by the blocking rods 45, so the gas pressure will increase. At the same time, when the piston push rod 341 moves, it will drive the fixing block 44 to move. The fixing block 44 will drive the jet pipe 43 to move, so that the jet pipe 43 is close to the blank 24.
[0051] The pushing component 5 includes six spring rotating blocks 51 set on the top of the forging table 1. Two sliding blocks 52 are slidably connected to the side walls of the three fixed frames 31. The outer walls of the six spring rotating blocks 51 are rotatably connected to the inner walls of the six sliding blocks 52. The side walls of the six spring rotating blocks 51 are fixedly connected to the side walls of the six sliding blocks 52 by arc springs.
[0052] Each of the three fixed frames 31 has two fixed brackets 53 fixedly connected to its side wall, and each of the six fixed brackets 53 has a push rod 531 slidably connected to its inner wall.
[0053] The pushing assembly 5 also includes two spring return rods 54 fixedly connected to the side wall of the fixed frame 31. The side walls of the six pushing rods 531 are rotatably connected to connecting rods 532. The six connecting rods 532 are in pairs. The bottom of the three spring pressing plates 42 are rotatably connected to the inner walls of the three sets of connecting rods 532.
[0054] The outer walls of the six spring reset rods 54 are slidably connected to the inner walls of the six sliding blocks 52. The bottoms of the six spring rotating blocks 51 are fixedly connected to cleaning steel brushes 55. The top of the spring rotating blocks 51 is equipped with an air jet assembly 6. When the spring pressing plate 42 descends, it pushes the connecting rod 532 to rotate, causing the connecting rod 532 to push the push rod 531 to move towards the spring rotating block 51. At the same time, the spring pressing plate 42 pushes the spring rotating block 51 to descend, causing the sliding block 52 to descend, so that the spring reset rods 54 are squeezed and accumulate rebound force until the cleaning steel brushes 55 at the bottom of the spring rotating block 51 contact the top of the forging table 1. At this time, the push rod 531 will contact the spring rotating block 51, thereby pushing the spring rotating block 51 to rotate, so that the spring rotating block 51 and the cleaning steel brushes 55 move away from the spring clamping block 35, and push the oxide around the spring clamping block 35 to move.
[0055] The jet assembly 6 includes a connecting frame 61 fixedly connected to the top of the spring rotating block 51, a spring reset plate 62 slidably connected to the inner wall of each of the six connecting frames 61, a fixing plate 63 fixedly connected to the side wall of each of the six sliding blocks 52, and an arc-shaped guide plate 64 fixedly connected to the side wall of each of the six connecting frames 61.
[0056] Each of the six spring reset plates 62 has a Z-shaped plate 65 fixedly connected to its side wall. The side walls of the six Z-shaped plates 65 are slidably connected to the inner walls of the six arc-shaped guide plates 64. When the spring rotating block 51 rotates, it will drive the connecting frame 61 to move. As the connecting frame 61 continues to move, the spring reset plate 62 will come into contact with the fixed plate 63, causing the spring reset plate 62 to be squeezed. The spring reset plate 62 will then move towards the arc-shaped guide plate 64, squeezing the gas in the connecting frame 61. When the spring reset plate 62 drives the Z-shaped plate 65 into the arc-shaped guide plate 64, the squeezed gas will be blocked by the Z-shaped plate 65.
[0057] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.
[0058] The method of using this auxiliary processing device includes the following steps:
[0059] S1: Workpiece placement: Place the heated blank 24 on top of the forging table 1;
[0060] S2: Position Adjustment: Start the servo motor 22 to drive the gear rod 23 to rotate. The gear rod 23 will drive the gear ring 21 to rotate, causing the fixed frame 31 to rotate. This will cause the ball 321 on the top of the spring pressure plate 32 to contact the inclined surface of the inclined ring 33, so that the spring pressure plate 32 is compressed and accumulates rebound force. The spring pressure plate 32 will then descend and compress the gas in the fixed frame 31. The gas pressure will increase due to compression until the high-pressure gas can push the piston rod 341 to move.
[0061] A specific application of this embodiment is as follows: When using this invention, the operator places the heated blank 24 on the top of the forging table 1, and then starts the servo motor 22 to drive the gear rod 23 to rotate. The gear rod 23 will drive the gear ring 21 to rotate, causing the fixed frame 31 to rotate. This allows the ball bearing 321 on the top of the spring pressure plate 32 to contact the inclined surface of the inclined ring 33, causing the spring pressure plate 32 to be compressed and accumulate rebound force. The spring pressure plate 32 will then descend and compress the gas inside the fixed frame 31. The gas pressure will increase due to compression until the high-pressure gas can push the piston rod. 341 moves, causing the spring clamping block 35 to move and contact the blank 24, pushing the blank 24 to move. Through the coordinated pushing of the three spring clamping blocks 35, the blank 24 is positioned at the center of the forging table 1 until the ball bearing 321 moves to the bottom of the inclined ring 33. At this time, the spring pressure plate 32 will contact the piston rod 361, squeezing the piston rod 361 to descend. The piston rod 361 will squeeze the hydraulic oil in the oil pipe 36, and the hydraulic oil will push the piston rod 362 to move. The piston rod 362 will push the spring clamping block 35 to move again, allowing it to accumulate rebound force. When a greater clamping force is applied to the blank 24, the gear ring 21 rotates. Through the fixed frame 31 and the spring clamping block 35, the blank 24 can be rotated, thereby adjusting its forging position until the ball 321 rotates to the position of the arc-shaped groove 331. At this time, the spring force of the spring pressure plate 32 is released, causing the spring pressure plate 32 to rise and separate from the piston rod 361, thus reducing the pressure on the gas. The spring force of the spring clamping block 35 is also released, pushing the piston rod 362 back to its original position, thereby reducing the pressure on the blank 24. Then, the electric motor can be started. The machine 11 rotates, causing the swing rod 12 to rotate, which in turn causes the swing rod 14 to push the forging block 13 down to forge the blank 24. The gear ring 21 continues to rotate, causing the fixed frame 31 to move, and the ball 321 to move back to the bottom of the inclined ring 33, thereby driving the blank 24 to rotate until the ball 321 moves back to the position of the arc groove 331. This process is repeated, which can smoothly drive the blank 24 to rotate. It can also reduce the clamping force on the blank 24 when it is being forged, effectively preventing the clamping force on the blank 24 from being too large and affecting the size of the blank 24.
[0062] When the forging block 13 forges the blank 24 each time, the ball 321 will be located in the arc-shaped groove 331. When the forging block 13 separates from the blank 24, the gear ring 21 will drive the blank 24 to rotate through the spring clamping block 35.
[0063] Secondly, when the spring pressure plate 32 moves from the arc-shaped groove 331 to the bottom of the inclined ring 33, the descent of the spring pressure plate 32 will push the spring pressing plate 42 to descend. When the spring pressing plate 42 moves to cover the air hole 411, the spring pressing plate 42 will squeeze the gas in the gas collecting frame 41. At this time, the squeezed gas will be blocked by the blocking rod 45, so the gas pressure will increase. At the same time, when the piston push rod 341 moves, it will drive the fixed block 44 to move. The fixed block 44 will drive the jet pipe 43 to move, so that the jet pipe 43 is close to the blank 24 until the jet pipe 43 separates from the blocking rod 45. The gas will enter the jet pipe 43, and the high-pressure gas will be sprayed out through the jet pipe 43 to the area around the spring clamping block 35 to clean the oxide around the spring clamping block 35. This effectively prevents the oxide that falls off the blank 24 during forging from accumulating around the blank 24. When the spring clamping block 35 moves, it may push the oxide to adhere to the surface of the blank 24, affecting the forging quality.
[0064] When the ball bearing 321 moves to the position of the arc-shaped groove 331 again, the spring pressure plate 32 will rise, the spring pressure plate 42 will release its rebound force, and the spring pressure plate 42 will return to its original position, so that the air hole 411 can communicate with the inside of the air collection frame 41 again to replenish the gas.
[0065] Secondly, when the spring pressing plate 42 descends, it will push the connecting rod 532 to rotate, causing the connecting rod 532 to push the push rod 531 to move towards the spring rotating block 51. At the same time, the spring pressing plate 42 will push the spring rotating block 51 to descend, causing the sliding block 52 to descend, so that the spring return rod 54 is squeezed and accumulates rebound force until the cleaning steel brush 55 at the bottom of the spring rotating block 51 contacts the top of the forging table 1. At this time, the push rod 531 will contact the spring rotating block 51, thereby pushing the spring rotating block 51 to rotate, so that the spring rotating block 51 and the cleaning steel brush 55 are away from the spring clamping block 35, pushing the oxide around the spring clamping block 35 to move, effectively preventing excessive oxide around the spring clamping block 35 and high-pressure gas, which makes it difficult to push the oxide to move a greater distance, affecting the separation of the oxide from the spring clamping block 35;
[0066] Secondly, when the spring rotating block 51 rotates, it will drive the connecting frame 61 to move. As the connecting frame 61 continues to move, the spring reset plate 62 will come into contact with the fixed plate 63, causing the spring reset plate 62 to be squeezed. The spring reset plate 62 will then move towards the arc-shaped guide plate 64, squeezing the gas inside the connecting frame 61. When the spring reset plate 62 drives the Z-shaped plate 65 into the arc-shaped guide plate 64, the squeezed gas will be blocked by the Z-shaped plate 65, so the gas pressure will increase until the bottom of the Z-shaped plate 65 moves to the arc surface inside the arc-shaped guide plate 64. At this time, a gap will appear between the arc-shaped guide plate 64 and the Z-shaped plate 65, and the high-pressure gas will spray out from the arc-shaped guide plate 64 through the gap onto the cleaning steel brush 55, cleaning the oxides attached to the cleaning steel brush 55. This effectively prevents the cleaning steel brush 55 from accumulating too much oxide, which may fall onto the top of the forging table 1 during reuse, causing secondary pollution.
