Description

Technical Field

[0001] The present invention relates to the technical field of valve processing equipment, and in particular to an auxiliary processing device for forging a valve blank and a use method thereof. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. In the production and preparation of valves, the raw materials are generally processed into blanks through a series of processes such as cutting, calcining, and forging. The blanks are then subjected to rough processing and fine processing in turn to produce valve components with reliable quality. During the forging process of valve blanks, a variety of auxiliary processing devices are usually used to ensure the quality and accuracy of forging.

[0003] Among them, when forging the valve blank, in order to ensure the quality of the blank, it is usually necessary to frequently rotate the position of the blank, and the blank usually needs to be clamped and fixed. However, when the blank is forged, the outer diameter of the blank will usually increase. After the blank is fixed, the plastic flow of the metal may be restricted, resulting in difficulty in evenly distributing the metal, thereby affecting the forming quality of the blank. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an auxiliary processing device for forging a valve blank, comprising a forging table, a motor is fixedly connected to the side wall of the forging table, a swinging rod is rotatably connected to the inner wall of the forging table, a forging block is slidably connected to the inner wall of the forging table, and a rocking rod is rotatably connected to the outer wall of the swinging rod;

[0005] The adjusting mechanism includes a blank, a gear ring for adjusting the position of the blank, a servo motor, a gear rod, and a limit assembly for limiting the clamping of the blank;

[0006] The bottom of the blank is placed on the top of the forging table, and a gear ring is rotatably connected to the outer wall of the forging table. 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. The outer wall of the gear rod is meshed with the outer wall of the gear ring, and the output end of the motor at the side wall is fixedly connected to the side wall of the swing rod. The inner wall of the swing rod is rotatably connected to the top of the forging block. The staff places the heated blank on the top of the forging table, and then starts the servo motor to drive the gear rod to rotate, and the gear rod drives the gear ring to rotate. The fixed frame is rotated to allow the ball on the top of the spring pressure plate to contact the inclined surface of the bevel ring, so that the spring pressure plate is squeezed to accumulate rebound force, and the spring pressure plate will drop to squeeze the gas in the fixed frame. The gas pressure will increase when it is squeezed until the high-pressure gas can push the piston push rod to move, drive the spring clamping block to move and contact the blank, push the blank to move, and push the blank in the center of the forging table through the coordinated push of the three spring clamping blocks until the ball moves to the bottom of the bevel ring. At this time, the spring pressure plate will contact the piston rod and squeeze the piston rod to drop. , the piston rod 1 will squeeze the hydraulic oil in the oil pipe, the hydraulic oil will push the piston rod 2 to move, the piston rod 2 will push the spring clamping block to move again, so that it can accumulate rebound force and apply greater clamping force to the blank. At this time, the gear ring rotates, and the blank can be driven to rotate through the fixed frame and the spring clamping block, thereby adjusting the forging position of the blank until the ball rotates to the position of the arc groove. At this time, the rebound force of the spring pressure plate will be released, allowing the spring pressure plate to rise and separate from the piston rod 1, while reducing the squeezing force on the gas, and the rebound force of the spring clamping block will be released. Push the piston rod back to its second position to reduce the extrusion pressure on the blank, then start the motor to rotate, drive the swing rod to rotate, let the rocking rod push the forging block down, forge the blank, and the gear ring continues to rotate to move the fixed frame, so that the ball moves to the bottom of the bevel ring again, thereby driving the blank to rotate until the ball moves to the position of the arc groove again. This reciprocating process can smoothly drive the blank to rotate, and can also reduce the clamping force on the blank when the blank is forged, effectively preventing the clamping force on the blank from being too large and affecting the size of the blank.

[0007] Preferably, the limit assembly includes three fixed frames fixedly connected to the top of the gear ring, the inner walls of the three fixed frames are slidably connected with spring pressure plates, the tops of the three spring pressure plates are rotatably connected with balls, the outer wall of the forging table is fixedly connected with a bevel ring, and the bottom of the bevel ring is provided with twelve arc grooves;

When the spring pressure plate moves from the arc groove to the bottom of the bevel ring again, the spring pressure plate descends and pushes the spring pressing plate to descend. 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 fixed block to move, and the injection pipe will be driven to move through the fixed block, so that the injection pipe is close to the blank.

[0013] Preferably, the pushing assembly includes six spring rotating blocks arranged 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 through arc springs;

[0014] Among them, two fixing frames are fixedly connected to the side walls of the three fixing frames, and pushing rods are slidably connected to the inner walls of the six fixing frames.

[0016] Among them, the outer walls of the six spring return rods are slidably connected to the inner walls of the six sliding blocks, the bottoms of the six spring rotating blocks are fixedly connected with cleaning steel brushes, and the top of the spring rotating block is provided with an injection assembly. When the spring pressing plate descends, it will push the connecting rod to rotate, so that the connecting rod pushes the pushing rod to move toward the spring rotating block. At the same time, the spring pressing plate will push the spring rotating block to descend, drive the sliding block to descend, and let the spring return rod be squeezed to accumulate rebound force until the cleaning steel brush at the bottom of the spring rotating block contacts with the top of the forging table. At this time, the pushing rod will contact with 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 push the oxide around the spring clamping block to move.

[0017] Preferably, the jet assembly comprises a connection frame fixedly connected to the top of the spring rotating block, the inner walls of the six connection frames are all slidably connected with spring reset plates, the side walls of the six sliding blocks are all fixedly connected with fixed plates, and the side walls of the six connection frames are all fixedly connected with arc guide plates;

[0018] Among them, the side walls of the six spring reset plates are fixedly connected with Z-shaped plates, and 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 contact the fixed plate, so that the spring reset plate is squeezed, and the spring reset plate will move toward the arc-shaped guide plate to squeeze 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 processing device for forging a valve blank comprises the following steps:

[0020] S1: Workpiece placement: Place the heated blank on the top of the forging table;

[0021] S2: Position adjustment: Start the servo motor to drive the gear rod to rotate, and the gear rod will drive the gear ring to rotate, so that the fixed frame rotates, and the ball on the top of the spring pressure plate contacts the inclined surface of the bevel ring, so that the spring pressure plate is squeezed and accumulates rebound force. The spring pressure plate will then drop to squeeze the gas in the fixed frame, and the pressure of the gas will increase when it is squeezed until the high-pressure gas can push the piston push rod to move.

[0022] The present invention has the following beneficial effects:

[0023] (1) When the present invention is used, the staff places the heated blank on the top of the forging table, and 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, allowing the ball on the top of the spring pressure plate to contact the inclined surface of the bevel ring, so that the spring pressure plate is squeezed and accumulates rebound force. The spring pressure plate will then drop to squeeze the gas in the fixed frame. The gas pressure will increase when it is squeezed until the high-pressure gas can push the piston push rod to move, driving the spring clamping block to move and contact the blank, pushing the blank to move, and through the coordinated push of the three spring clamping blocks, the blank is placed at the center of the forging table until the ball moves to the bottom of the bevel ring. At this time, the spring pressure plate will contact piston rod one, squeezing piston rod one down, piston rod one will squeeze the hydraulic oil in the oil pipe, and the hydraulic oil will push piston rod two to move. Piston rod two will push the spring clamping block to move again, so that it accumulates rebound force, exerting force on the blank. The spring clamping block is released to push the piston rod back to its original position, thereby reducing the extrusion pressure on the blank. Then the motor can be started to rotate, driving the swinging rod to rotate, allowing the swinging rod to push the forging block down to forge the blank. The gear ring continues to rotate to move the fixed frame, allowing the ball to move to the bottom of the bevel ring again, thereby driving the blank to rotate until the ball moves to the position of the arc groove again. This reciprocating process can smoothly drive the blank to rotate, and can also reduce the clamping force on the blank when the blank is forged, effectively preventing the clamping force on the blank from being too large and affecting the size of the blank.

[0024] (2) In the present invention, when the spring pressure plate moves from the arc groove to the bottom of the bevel ring again, the spring pressure plate descends and pushes the spring pressing plate to descend. 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 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, and the fixed block will drive the jet pipe to move, so that the jet pipe is close to the blank until the jet pipe is separated from the blocking rod. The gas will enter the jet pipe, and the high-pressure gas will be sprayed around the spring clamping block through the jet pipe to clean the oxide around the spring clamping block, effectively preventing the oxide from falling when the blank is forged and 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 of the present invention descends, it will push the connecting rod to rotate, so that the connecting rod pushes the pushing rod to move toward the spring rotating block. At the same time, the spring pressing plate will push the spring rotating block to descend, driving the sliding block to descend, so that the spring return 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 pushing rod will contact the spring rotating block, thereby pushing the spring rotating block to rotate, allowing the spring rotating block and the cleaning steel brush to move away from the spring clamping block, pushing the oxide around the spring clamping block to move, effectively preventing excessive oxide around the spring clamping block. The high-pressure gas makes it difficult to push the oxide to move a longer distance, affecting the separation of the oxide from the spring clamping block.

[0026] (4) When the spring rotating block of the present invention rotates, it will drive the connecting frame to move. As the connecting frame continues to move, the spring reset plate will contact the fixed plate, causing the spring reset plate to be squeezed. The spring reset plate will then move toward the arc-shaped guide plate to squeeze the gas in the connecting frame. When the spring reset plate drives the Z-shaped plate to enter 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-shaped surface in the arc-shaped guide plate. At this time, a gap will leak out between the arc-shaped guide plate and the Z-shaped plate, and high-pressure gas will pass through the gap and spray out from the arc-shaped guide plate toward the cleaning steel brush, thereby cleaning the oxides attached to the cleaning steel brush, effectively preventing excessive accumulation of oxides on the cleaning steel brush. When the cleaning steel brush is used again, these oxides may fall on the top of the forging table, causing secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] For example, see Figure 1 - Figure 6The present invention is an auxiliary processing device for forging a valve blank, comprising a forging table 1, a motor 11 is fixedly connected to the side wall of the forging table 1, a swinging rod 12 is rotatably connected to the inner wall of the forging table 1, a forging block 13 is slidably connected to the inner wall of the forging table 1, and a rocking rod 14 is rotatably connected to the outer wall of the swinging rod 12;

[0043] The adjusting mechanism 2 includes a blank 24, a gear ring 21 for adjusting the position of the blank 24, a servo motor 22, a gear rod 23, and a limit assembly 3 for limiting and clamping the blank 24;

[0044] The bottom of the blank 24 is placed on the top of the forging table 1, and the gear ring 21 is rotatably connected to the outer wall of the forging table 1. The servo motor 22 is fixedly connected to the side wall of the forging table 1. The top output end of the servo motor 22 is fixedly connected to the gear rod 23. The outer wall of the gear rod 23 is meshed with the outer wall of the gear ring 21. The output end of the side wall 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 staff 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, so that the fixed frame 31 rotates, so that the ball 321 on the top of the spring pressure plate 32 contacts the inclined surface of the bevel ring 33, so that the spring pressure plate 32 is squeezed, so that it accumulates resilience, and the spring pressure plate 32 will go down to squeeze the gas in the fixed frame 31, and the gas pressure will increase when it is squeezed, until the high-pressure gas can push the piston push rod 341 to move, drive the spring clamping block 35 to move and contact the blank 24, push the blank 24 to move, and through the coordinated push of the three spring clamping blocks 35, the blank 24 is at the center of the forging table 1, until the ball 321 moves to the bottom of the bevel ring 33, at this time, the spring pressure plate 32 will contact the piston rod 361, squeeze the piston rod 361 down, and the activity The plug rod 1 361 will squeeze the hydraulic oil in the oil pipe 36, and the hydraulic oil will push the piston rod 2 362 to move. The piston rod 2 362 will push the spring clamping block 35 to move again, so that it accumulates rebound force and applies a greater clamping force to the blank 24. At this time, the gear ring 21 rotates, and the blank 24 can be driven to rotate through the fixed frame 31 and the spring clamping block 35, thereby adjusting the forging position of the blank 24 until the ball 321 rotates to the position of the arc groove 331. At this time, the rebound force of the spring pressure plate 32 will be released, allowing the spring pressure plate 32 to rise and separate from the piston rod 1 361, while reducing the squeezing force on the gas. The rebound force of the spring clamping block 35 will be released, pushing The piston rod 362 returns to its original position, thereby reducing the squeezing pressure on the blank 24.

The gear ring 21 continues to rotate, causing the fixed frame 31 to move, allowing the ball 321 to move to the bottom of the bevel ring 33 again, thereby driving the blank 24 to rotate until the ball 321 moves to the position of the arc groove 331 again. This reciprocating process can smoothly drive the blank 24 to rotate, and can also reduce the clamping force on the blank 24 when the blank 24 is forged, effectively preventing the clamping force on the blank 24 from being too large and affecting the size of the blank 24.

[0060] S2: Position adjustment: Start the servo motor 22 to drive the gear rod 23 to rotate, and the gear rod 23 will drive the gear ring 21 to rotate, so that the fixed frame 31 rotates, and the ball 321 on the top of the spring pressure plate 32 contacts the inclined surface of the bevel ring 33, so that the spring pressure plate 32 is squeezed and accumulates resilience. The spring pressure plate 32 will then drop to squeeze the gas in the fixed frame 31, and the pressure of the gas will increase until the high-pressure gas can push the piston push rod 341 to move.

[0061] A specific application of this embodiment is: when the present invention is used, the staff 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, and the gear rod 23 will drive the gear ring 21 to rotate, so that the fixed frame 31 rotates, so that the ball 321 on the top of the spring pressure plate 32 contacts the inclined surface of the bevel ring 33, so that the spring pressure plate 32 is squeezed and accumulates resilience, and the spring pressure plate 32 will drop to squeeze the gas in the fixed frame 31, and the pressure of the gas will increase when it is squeezed until the high-pressure gas can push the piston push rod 341 moves, driving the spring clamping block 35 to move and contact the blank 24, pushing the blank 24 to move, and the three spring clamping blocks 35 work together to push the blank 24 to the center of the forging table 1 until the ball 321 moves to the bottom of the bevel ring 33. At this time, the spring pressure plate 32 will contact the piston rod 1 361, squeezing the piston rod 1 361 to descend, and the piston rod 1 361 will squeeze the hydraulic oil in the oil pipe 36, and the hydraulic oil will push the piston rod 2 362 to move, and the piston rod 2 362 will push the spring clamping block 35 to move again, so that it accumulates resilience, The blank 24 applies a greater clamping force. At this time, the gear ring 21 rotates, and the blank 24 can be driven to rotate through the fixed frame 31 and the spring clamping block 35, thereby adjusting the forging position of the blank 24 until the ball 321 rotates to the position of the arc groove 331. At this time, the rebound force of the spring pressure plate 32 will be released, allowing the spring pressure plate 32 to rise and separate from the piston rod 1 361, while reducing the squeezing force on the gas. The rebound force of the spring clamping block 35 will be released, pushing the piston rod 2 362 back to its original position, thereby reducing the squeezing pressure on the blank 24, and then the electric The machine 11 rotates, driving the swinging rod 12 to rotate, allowing the rocking rod 14 to push the forging block 13 down, and forging the blank 24. The gear ring 21 continues to rotate, so that the fixed frame 31 moves, allowing the ball 321 to move to the bottom of the bevel ring 33 again, thereby driving the blank 24 to rotate until the ball 321 moves to the position of the arc groove 331 again. In this way, the blank 24 can be smoothly driven to rotate, and the clamping force on the blank 24 can be reduced when the blank 24 is forged, effectively preventing the clamping force on the blank 24 from being too large, thereby affecting the size of the blank 24.

[0062] Each time the forging block 13 forges the blank 24, the ball 321 will be located in the arc-shaped groove 331. When the forging block 13 is separated 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 groove 331 to the bottom of the bevel ring 33 again, the spring pressure plate 32 descends and pushes 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 squeezes 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, and the fixed block 44 will drive the injection pipe 43 to move, so that the injection pipe 43 is close to the blank 24 until the injection pipe 43 is separated from the blocking rod 45, and the gas will enter the injection pipe 43. The high-pressure gas will be ejected around the spring clamping block 35 through the injection pipe 43 to clean the oxide around the spring clamping block 35, effectively preventing the oxide from falling when the blank 24 is forged and 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 quality of forging.

[0064] When the ball 321 moves to the position of the arc groove 331 again, the spring pressure plate 32 will rise, the resilience of the spring pressing plate 42 will be released, and the spring pressing plate 42 will return to its original position, so that the air hole 411 is connected to the inside of the gas collecting 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, so that the connecting rod 532 pushes the pushing rod 531 to move toward the spring rotating block 51. At the same time, the spring pressing plate 42 will push the spring rotating block 51 to descend, driving the sliding block 52 to descend, so that the spring return rod 54 is squeezed and accumulates resilience 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 pushing 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 too much oxide around the spring clamping block 35, and high-pressure gas, It is difficult to push the oxide to move a longer distance, affecting the separation of the oxide and 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 contact the fixed plate 63, so that the spring reset plate 62 will be squeezed, and the spring reset plate 62 will move toward the arc guide plate 64 to squeeze the gas in the connecting frame 61. When the spring reset plate 62 drives the Z-shaped plate 65 to enter the arc 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 in the arc guide plate 64. At this time, a gap will leak out between the arc guide plate 64 and the Z-shaped plate 65, and the high-pressure gas will pass through the gap and spray out from the arc guide plate 64 toward the cleaning steel brush 55 to clean the oxide attached to the cleaning steel brush 55, effectively preventing excessive accumulation of oxides on the cleaning steel brush 55. When used again, these oxides may fall on the top of the forging table 1, causing secondary pollution.
