Description

Technical Field

[0001] This invention relates to the field of valve processing equipment technology, specifically to a thread-cutting device for fire extinguisher valve components and its usage method. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and overflow pressure relief. Fire extinguisher valves are a key component of fire extinguishers, mainly used to control the opening and closing of the fire extinguisher and the release of the extinguishing agent. Their functions include sealing, withstanding high pressure, and rapidly releasing the extinguishing agent during use. Fire extinguisher valves typically consist of multiple components, such as the valve body, valve core, valve cover, and pressure gauge interface. During the production of fire extinguisher valves, thread-machining equipment is often required to process the valve threads.

[0003] When threading fire extinguisher valves, thread rolling wheels are often used. During the process, the fire extinguisher valve also needs to rotate. However, the shape of the fire extinguisher valve is irregular, which can easily cause the valve's center of gravity to change. This may cause the valve to shake during rotation, affecting the stability of the process. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a threading device for fire extinguisher valve components, including a housing, a base fixedly connected to the inner wall of the housing, two sliding blocks slidably connected to the top of the base, two electric telescopic rods fixedly connected to the top of the base, and the output ends of the side walls of the two electric telescopic rods being fixedly connected to the side walls of the two sliding blocks.

[0005] The thread rolling mechanism includes a fire extinguisher valve, a thread rolling wheel for machining the threads of the fire extinguisher valve, a motor, a mounting bracket, and a limiting component for restricting and holding the fire extinguisher valve.

[0006] There are two thread rolling wheels and two motors. The outer walls of the two thread rolling wheels are rotatably connected to the inner walls of the two sliding blocks, and the side walls of the two sliding blocks are fixedly connected to the side walls of the two motors.

[0007] The output ends of both motors are fixedly connected to the side walls of two thread rolling wheels. The bottom of the placement rack is fixedly connected to the top of the outer casing. The outer wall of the fire extinguisher valve is placed on top of the placement rack. The operator opens the protective door on the outer casing, places the fire extinguisher valve to be processed on the placement rack, closes the protective door, starts the motor to drive the thread rolling wheels to rotate, and then starts the electric telescopic rod to push the sliding block towards the fire extinguisher valve, bringing the thread rolling wheels close to the fire extinguisher valve. As the sliding block in front continues to move, it will cause the inclined surface of the inclined block to contact the push frame, squeezing the push frame and moving it towards the placement rack, so that the push frame contacts the spring sliding frame, pushing the spring sliding frame to move and allowing the spring sliding frame to accumulate rebound force. When the spring sliding frame moves, it will push the connecting rod to rotate, causing the connecting rod to fold and push the arc-shaped block towards the inner wall of the fire extinguisher valve. The directional movement causes the arc-shaped expansion bladder to move. Simultaneously, as the spring sliding frame moves, it also moves the compression ring, compressing the gas inside the air cylinder. The compressed gas enters the arc-shaped expansion bladder through the telescopic tube, causing it to inflate initially until the inclined surface of the inclined block separates from the pushing frame. The arc-shaped expansion bladder then contacts the inner wall of the fire extinguisher valve, flexibly clamping it. The sliding block continues to move until the thread rolling wheel contacts the fire extinguisher valve, compressing it. The rotation of the thread rolling wheel causes the fire extinguisher valve to rotate, threading it. By flexibly clamping the fire extinguisher valve, a uniform supporting force is applied, reducing the impact of center of gravity shift during rotation and effectively preventing the irregular shape of the fire extinguisher valve from causing wobbling during rotation, thus ensuring the stability of its rotation process.

[0008] Preferably, the limiting component includes a fixed block fixedly connected to the top of the base, a rotating rod rotatably connected to the inner wall of the fixed block, an inclined block fixedly connected to the back of the sliding block located on the front, and a pusher slidably connected to the inner wall of the fixed block.

[0009] The rotating rod is slidably connected to a spring sliding frame on its outer wall, and a pneumatic cylinder is fixedly connected to its outer wall.

[0010] Preferably, the limiting component further includes three arc-shaped blocks disposed on the outer wall of the rotating rod. Two connecting rods are rotatably connected to the side of each of the three arc-shaped blocks near the outer wall of the rotating rod, and the inner walls of the three connecting rods on the left side are rotatably connected to the outer wall of the rotating rod.

[0011] Among them, the inner walls of the three connecting rods on the right side are slidably connected to the outer wall of the spring sliding frame, and the side wall of the fixed block is provided with an incremental component.

[0012] Preferably, the limiting component further includes a compression ring slidably connected to the inner wall of the air cylinder, the side wall of the compression ring being fixedly connected to the side wall of the spring sliding frame, three telescopic tubes being connected through the inner wall of the air cylinder, and arc-shaped expansion bladders being fixedly connected to the side of the three arc-shaped blocks away from the outer wall of the rotating rod, and the outer walls of the three telescopic tubes being connected through the inner walls of the three arc-shaped expansion bladders.

[0013] Preferably, the incremental component includes a pneumatic frame 1 fixedly connected to the side wall of the fixed block, a piston plate 1 slidably connected to the inner wall of the pneumatic frame 1, a connecting rod 2 rotatably connected to the bottom of the piston plate 1, and the side wall of the push frame rotatably connected to the inner wall of the connecting rod 2.

[0014] The top of the air pressure frame is connected to the gas supply pipe, and the bottom of the piston plate is fixedly connected to the connecting rod. When the push frame moves towards the fire extinguisher valve, it will also drive the connecting rod to move, causing the connecting rod to rotate, pushing the piston plate to rise and compressing the gas in the air pressure frame.

[0015] Preferably, the incremental component further includes a communicating groove formed on the inner wall of the rotating rod, a rotating ring rotatably connected to the outer wall of the rotating rod, the inner wall of the rotating ring being connected to the outer wall of the first gas supply pipe, two protrusions fixedly connected to the outer wall of the rotating rod, and a gas blocking pipe fixedly connected to the inner wall of the rotating ring.

[0016] The gas-blocking tube has a spring-loaded inclined ring slidably connected to its inner wall, and a blocking component is installed on the side wall of the fixed block. The compressed gas enters the rotating ring through the gas supply tube. At this time, the gas is blocked by the spring-loaded inclined ring, thus generating high pressure. When the fire extinguisher valve is turned, the supporting force of the arc-shaped expansion bladder on the fire extinguisher valve will drive the arc-shaped expansion bladder to rotate, thereby driving the rotating rod to rotate and causing the protrusion to rotate. When the protrusion rotates and contacts the spring-loaded inclined ring, it will squeeze the spring-loaded inclined ring to descend, causing the spring-loaded inclined ring to separate from the inclined surface in the gas-blocking tube, thus removing the obstruction to the gas. At this time, the high-pressure gas will enter the connecting groove through the gas-blocking tube, enter the air pressure cylinder through the connecting groove, and finally enter the arc-shaped expansion bladder, causing the arc-shaped expansion bladder to expand again.

[0017] Preferably, the blocking assembly includes a second pneumatic frame fixedly connected to the side wall of the fixed block, a second piston plate slidably connected to the inner wall of the second pneumatic frame, the bottom of the second piston plate being fixedly connected to the top of the connecting rod, three air holes being opened on the outer wall of the second pneumatic frame, and a second air supply pipe being connected through the top of the second pneumatic frame.

[0018] The inner wall of the second gas supply pipe is connected to an air inlet pipe, and the inner wall of the air inlet pipe is slidably connected to an air inlet one-way valve. The outer wall of the air inlet pipe is connected to the inner wall of the second pressure frame. When the first piston plate rises, it will drive the connecting rod to rise, and the connecting rod will drive the second piston plate to rise, so that the second piston plate will compress the gas in the second pressure frame. As the second piston plate continues to move, the gas pressure in the second pressure frame will increase.

[0019] Preferably, the blocking assembly further includes a spring push rod slidably connected to the inner wall of the second gas pipe, a Z-shaped blocking plate fixedly connected to the top of the spring push rod, the outer wall of the Z-shaped blocking plate slidably connected to the inner wall of the rotating ring, and a fixing frame fixedly connected to the top of the Z-shaped blocking plate.

[0020] The fixed frame has a spring inclined block slidably connected to its inner wall, and a spring snap rod slidably connected to its inner wall. The high-pressure gas will push the spring push rod to rise, which will drive the Z-shaped baffle plate to rise, so that the Z-shaped baffle plate is close to the gas blocking pipe and blocks the gas blocking pipe. When the spring inclined ring descends, the high-pressure gas in the gas delivery pipe can only enter the connecting groove through the groove on the Z-shaped baffle plate.

[0021] Preferably, the blocking assembly further includes an inclined plate fixedly connected to the top of the second gas pipe, an outlet pipe fixedly connected to the inner wall of the rotating ring, and a spring blocking rod slidably connected to the side wall of the rotating ring.

[0022] A fixed rod is fixedly connected to the side wall of the rotating ring. The outer wall of the spring blocking rod is slidably connected to the inner wall of the air outlet pipe. When the Z-shaped baffle plate rises, it will drive the fixed frame and the spring inclined block to rise, causing the inclined surface of the spring inclined block to squeeze the spring blocking rod to move, so that the spring blocking rod enters the air outlet pipe and blocks the air outlet pipe. As the spring inclined block continues to move, the spring inclined block will contact the fixed rod, blocking the spring inclined block and stopping its movement. The fixed frame continues to move and will squeeze the spring at the bottom of the spring inclined block, causing it to accumulate rebound force. During the continuous movement of the fixed frame, it will also drive the spring locking rod to rise.

[0023] A method for using a thread-machining device for fire extinguisher valve components includes the following steps:

[0024] S1: Workpiece Placement: The worker opens the protective door on the outer casing and then places the fire extinguisher valve to be processed on the placement rack;

[0025] S2: Start the equipment: Start the motor to drive the thread rolling wheel to rotate, then start the electric telescopic rod to push the sliding block towards the fire extinguisher valve, so that the thread rolling wheel is close to the fire extinguisher valve;

[0026] S3: Workpiece clamping: During the continuous movement of the sliding block located on the front, the inclined surface of the inclined block will come into contact with the push frame, squeezing the push frame and causing the push frame to move towards the placement frame, so that the push frame comes into contact with the spring sliding frame and pushes the spring sliding frame to move.

[0027] The present invention has the following beneficial effects:

[0028] (1) When using this invention, the operator opens the protective door on the outer shell, places the fire extinguisher valve to be processed on the placement rack, closes the protective door, starts the motor to drive the thread rolling wheel to rotate, and then starts the electric telescopic rod to push the sliding block towards the fire extinguisher valve, so that the thread rolling wheel is close to the fire extinguisher valve. During the continuous movement of the sliding block located on the front, it will drive the inclined surface of the inclined block to contact the push frame, squeeze the push frame, and move the push frame towards the placement rack, so that the push frame contacts the spring sliding frame, pushes the spring sliding frame to move, and allows the spring sliding frame to accumulate rebound force. When the spring sliding frame moves, it will push the connecting rod to rotate, causing the connecting rod to fold, pushing the arc-shaped block towards the inner wall of the fire extinguisher valve, driving the arc-shaped expansion bladder to move. At the same time, when the spring sliding frame moves, It also drives the compression ring to move, compressing the gas inside the air cylinder. The compressed gas enters the arc-shaped expansion bladder through the telescopic tube, causing the arc-shaped expansion bladder to inflate and expand initially until the inclined surface of the inclined block separates from the push frame. The arc-shaped expansion bladder then contacts the inner wall of the fire extinguisher valve, flexibly clamping the fire extinguisher valve. The sliding block continues to move until the thread rolling wheel contacts the fire extinguisher valve, compressing the fire extinguisher valve. The rotation of the thread rolling wheel drives the fire extinguisher valve to rotate, performing thread machining on the fire extinguisher valve. By flexibly clamping the fire extinguisher valve, a uniform supporting force is applied, reducing the impact of the center of gravity shift on the fire extinguisher valve during rotation. This effectively prevents the irregular shape of the fire extinguisher valve from causing shaking during rotation, ensuring the stability of its rotation process.

[0029] (2) When the pusher moves toward the fire extinguisher valve, it also moves the connecting rod 2, causing the connecting rod 2 to rotate and push the piston plate 1 to rise, compressing the gas in the gas pressure frame 1. The compressed gas enters the rotating ring through the gas supply pipe 1. At this time, the gas is blocked by the spring inclined ring, so the gas will generate high pressure. When the fire extinguisher valve rotates, the supporting force of the arc-shaped expansion bladder on the fire extinguisher valve will drive the arc-shaped expansion bladder to rotate, thereby driving the rotating rod to rotate, causing the protrusion to rotate. When the protrusion rotates and contacts the spring inclined ring, it will compress the spring inclined ring to descend, allowing the spring inclined ring to separate from the inclined surface in the gas blocking pipe, thus removing the obstruction of the gas. At this point, the high-pressure gas will enter the connecting groove through the gas-blocking pipe, then enter the air pressure cylinder through the connecting groove, and finally enter the arc-shaped expansion bladder, causing the arc-shaped expansion bladder to expand again. When the protrusion separates from the spring inclined ring, the rebound force of the spring inclined ring will be released, allowing the spring inclined ring to return to its original position and block the gas again. This process repeats, and as the thread rolling wheel gradually squeezes the fire extinguisher valve, the expansion amplitude of the arc-shaped expansion bladder gradually increases. This allows the supporting force of the arc-shaped expansion bladder to match the changing squeezing force of the thread rolling wheel, effectively balancing the squeezing force of the thread rolling wheel. This effectively prevents the squeezing force of the thread rolling wheel from gradually increasing, resulting in insufficient supporting force of the flexible clamp, which could easily lead to deformation of the fire extinguisher valve.

[0030] (3) When the piston plate 1 rises, it drives the connecting rod to rise, which in turn drives the piston plate 2 to rise, causing the piston plate 2 to compress the gas in the pressure frame 2. As the piston plate 2 continues to move, the gas pressure in the pressure frame 2 increases, and the high-pressure gas pushes the spring push rod to rise, causing the Z-shaped baffle plate to rise, bringing it closer to the gas blocking pipe and blocking it. When the spring inclined ring descends, the high-pressure gas in the gas delivery pipe 1 can only enter the connecting groove through the groove on the Z-shaped baffle plate. After some of the gas in the pressure frame 1 enters the connecting groove, the gas pressure in the pressure frame 1 will decrease, and the gas delivery pipe 2... The gas inside will enter the first pressure frame through the air inlet pipe and the one-way valve. At this time, the gas pressure in the second air inlet pipe will decrease, reducing the pushing force on the spring push rod. The spring push rod will then release its rebound force, causing it to drop and widen the gap between the Z-shaped baffle and the fixed frame, allowing more gas to flow in. This effectively prevents the high-pressure gas in the first pressure frame from quickly entering the arc-shaped expansion bladder when the pressure is too high, causing it to initially expand too much. As the gas pressure in the arc-shaped expansion bladder increases, the gas pressure in the first pressure frame will decrease, making it difficult for subsequent gas to re-enter the connecting groove. This affects the expansion range of the arc-shaped expansion bladder and its compatibility with the extrusion force of the thread rolling wheel.

[0031] (4) When the Z-shaped baffle plate rises, it will drive the fixed frame and the spring inclined block to rise, causing the inclined surface of the spring inclined block to squeeze the spring blocking rod to move, so that the spring blocking rod enters the air outlet pipe and blocks the air outlet pipe. As the spring inclined block continues to move, the spring inclined block will contact the fixed rod, blocking the spring inclined block and stopping its movement. The fixed frame continues to move and will squeeze the spring at the bottom of the spring inclined block, causing it to accumulate rebound force. During the continuous movement of the fixed frame, it will also drive the spring locking rod to rise. When the spring locking rod moves to the notch position of the spring inclined block, since the spring locking rod was previously in a stretched state, the rebound force of the spring locking rod will be released, causing the spring locking rod to insert into the spring inclined block and fix it. At this time, the Z-shaped baffle plate The gas-blocking tube will be blocked. After the threads on the fire extinguisher valve are machined, the electric telescopic rod will retract, separating the thread rolling wheel from the fire extinguisher valve. At this time, because the gas in the second gas pressure frame is injected into the first gas pressure frame, the gas pressure in the second gas pressure frame is low, and the pushing force on the spring push rod is low. Therefore, the Z-shaped blocking plate and the fixed frame will descend. Because the spring inclined block is stuck, the fixed frame descends, which will drive the spring inclined block to descend and separate from the spring blocking rod. The rebound force of the spring blocking rod will be released, causing the spring blocking rod to separate from the gas outlet pipe. At this time, the high-pressure gas in the connecting groove will be discharged through the gas outlet pipe, reducing the expansion amplitude of the arc-shaped expansion bladder and effectively preventing the thread rolling wheel from separating from the fire extinguisher valve. The arc-shaped expansion bladder continues to exert a large squeezing force on the fire extinguisher valve, which can easily lead to deformation of the fire extinguisher valve.

[0044] 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.

[0045] Example 1, please refer to Figure 1 - Figure 5 The present invention is a threading device for fire extinguisher valve components, including a housing 1, a base 11 fixedly connected to the inner wall of the housing 1, two sliding blocks 12 slidably connected to the top of the base 11, two electric telescopic rods 13 fixedly connected to the top of the base 11, and the output ends of the side walls of the two electric telescopic rods 13 are fixedly connected to the side walls of the two sliding blocks 12.

[0046] The thread rolling mechanism 2 includes a fire extinguisher valve 23, a thread rolling wheel 21 for machining the thread of the fire extinguisher valve 23, a motor 22, a placement frame 24, and a limiting component 3 for limiting the clamping of the fire extinguisher valve 23.

[0047] There are two thread rolling wheels 21 and two motors 22. The outer walls of the two thread rolling wheels 21 are rotatably connected to the inner walls of the two sliding blocks 12, and the side walls of the two sliding blocks 12 are fixedly connected to the side walls of the two motors 22.

[0048] In this arrangement, the output ends of the two motors 22 are fixedly connected to the side walls of the two thread rolling wheels 21. The bottom of the placement rack 24 is fixedly connected to the top of the outer casing 1. The outer wall of the fire extinguisher valve 23 is placed on top of the placement rack 24. The operator opens the protective door on the outer casing 1, places the fire extinguisher valve 23 to be processed on the placement rack 24, closes the protective door, starts the motor 22 to drive the thread rolling wheels 21 to rotate, and then starts the electric telescopic rod 13 to push the sliding block 12 towards the fire extinguisher valve 23, allowing... As the thread rolling wheel 21 approaches the fire extinguisher valve 23, the continuous movement of the sliding block 12 located on the front causes the inclined surface of the inclined block 33 to contact the push frame 34, squeezing the push frame 34 and causing it to move towards the placement frame 24. This brings the push frame 34 into contact with the spring sliding frame 35, pushing the spring sliding frame 35 to move and accumulate rebound force. When the spring sliding frame 35 moves, it pushes the connecting rod 361 to rotate, causing the connecting rod 361 to fold and push the arc-shaped block 36 towards the fire extinguisher. The inner wall of valve 23 moves, causing the arc-shaped expansion bladder 38 to move. Simultaneously, as the spring sliding frame 35 moves, it also moves the compression ring 371, compressing the gas inside the air cylinder 37. The compressed gas enters the arc-shaped expansion bladder 38 through the telescopic tube 372, causing the arc-shaped expansion bladder 38 to inflate and begin its initial expansion until the inclined surface of the inclined block 33 separates from the push frame 34. The arc-shaped expansion bladder 38 then contacts the inner wall of the fire extinguisher valve 23, flexibly clamping the fire extinguisher valve 23. The sliding block 12... Continue moving until the thread rolling wheel 21 contacts the fire extinguisher valve 23, squeezing the fire extinguisher valve 23. The rotation of the thread rolling wheel 21 drives the fire extinguisher valve 23 to rotate, thus machining the threads of the fire extinguisher valve 23. By flexibly clamping the fire extinguisher valve 23, a supporting force is applied evenly, reducing the impact of the center of gravity shift on the fire extinguisher valve 23 during rotation. This effectively prevents the irregular shape of the fire extinguisher valve 23 from causing shaking during rotation, ensuring the stability of its rotation process.

[0049] Example 2, please refer to Figure 6 - Figure 9The present invention is a threading device for fire extinguisher valve components. Based on the first embodiment, the limiting component 3 includes a fixing block 31 fixedly connected to the top of the base 11, a rotating rod 32 rotatably connected to the inner wall of the fixing block 31, an inclined block 33 fixedly connected to the back of the sliding block 12 located on the front, and a pushing frame 34 slidably connected to the inner wall of the fixing block 31.

[0050] Among them, a spring sliding frame 35 is slidably connected to the outer wall of the rotating rod 32, and a pneumatic cylinder 37 is fixedly connected to the outer wall of the rotating rod 32.

[0051] The limiting component 3 also includes three arc-shaped blocks 36 disposed on the outer wall of the rotating rod 32. Two connecting rods 361 are rotatably connected to the side of the three arc-shaped blocks 36 near the outer wall of the rotating rod 32. The inner walls of the three connecting rods 361 on the left side are rotatably connected to the outer wall of the rotating rod 32.

[0052] Among them, the inner wall of the three connecting rods 361 on the right side is slidably connected to the outer wall of the spring sliding frame 35, and the side wall of the fixed block 31 is provided with an incremental component 4.

[0053] The limiting component 3 also includes a compression ring 371 slidably connected to the inner wall of the air cylinder 37. The side wall of the compression ring 371 is fixedly connected to the side wall of the spring sliding frame 35. Three telescopic tubes 372 are connected through the inner wall of the air cylinder 37. Arc-shaped expansion bladders 38 are fixedly connected to the side of the three arc-shaped blocks 36 away from the outer wall of the rotating rod 32. The outer walls of the three telescopic tubes 372 are all connected through the inner walls of the three arc-shaped expansion bladders 38.

[0054] The incremental component 4 includes a pneumatic frame 41 fixedly connected to the side wall of the fixed block 31, a piston plate 42 slidably connected to the inner wall of the pneumatic frame 41, a connecting rod 421 rotatably connected to the bottom of the piston plate 42, and the side wall of the push frame 34 rotatably connected to the inner wall of the connecting rod 421.

[0055] The top of the air pressure frame 41 is connected to the gas supply pipe 44, and the bottom of the piston plate 42 is fixedly connected to the connecting rod 43. When the push frame 34 moves toward the fire extinguisher valve 23, it will also drive the connecting rod 421 to move, causing the connecting rod 421 to rotate, pushing the piston plate 42 to rise and compress the gas in the air pressure frame 41.

[0056] The incremental component 4 also includes a connecting groove 451 opened on the inner wall of the rotating rod 32, a rotating ring 45 rotatably connected to the outer wall of the rotating rod 32, the inner wall of the rotating ring 45 being connected to the outer wall of the gas supply pipe 44, two protrusions 46 being fixedly connected to the outer wall of the rotating rod 32, and a gas blocking pipe 47 being fixedly connected to the inner wall of the rotating ring 45.

[0057] A spring-loaded inclined ring 48 is slidably connected to the inner wall of the gas-blocking tube 47, and a blocking component 5 is provided on the side wall of the fixed block 31. The compressed gas will enter the rotating ring 45 through the gas supply tube 44. At this time, the gas will be blocked by the spring-loaded inclined ring 48, so the gas will generate high pressure. When the fire extinguisher valve 23 is rotated, the supporting force of the arc-shaped expansion bladder 38 on the fire extinguisher valve 23 will drive the arc-shaped expansion bladder 38 to rotate, thereby driving the rotating rod 32 to rotate, causing the protrusion 46 to rotate. When the protrusion 46 rotates and contacts the spring-loaded inclined ring 48, it will squeeze the spring-loaded inclined ring 48 to descend, allowing the spring-loaded inclined ring 48 to separate from the inclined surface in the gas-blocking tube 47, thus removing the obstruction to the gas. At this time, the high-pressure gas will enter the connecting groove 451 through the gas-blocking tube 47, enter the air pressure cylinder 37 through the connecting groove 451, and finally enter the arc-shaped expansion bladder 38, causing the arc-shaped expansion bladder 38 to expand again.

[0058] The blocking assembly 5 includes a second pneumatic frame 51 fixedly connected to the side wall of the fixed block 31, a second piston plate 52 slidably connected to the inner wall of the second pneumatic frame 51, the bottom of the second piston plate 52 being fixedly connected to the top of the connecting rod 43, three air holes 511 being opened on the outer wall of the second pneumatic frame 51, and a second air supply pipe 53 being connected through the top of the second pneumatic frame 51.

[0059] Among them, the inner wall of the second air supply pipe 53 is connected to the air inlet pipe 54, and the inner wall of the air inlet pipe 54 is slidably connected to the air inlet one-way valve 541. The outer wall of the air inlet pipe 54 is connected to the inner wall of the second air pressure frame 51. When the piston plate 42 rises, it will drive the connecting rod 43 to rise. The specific model of the air inlet one-way valve 541 is ZG3 / 8. The connecting rod 43 drives the piston plate 52 to rise, so that the piston plate 52 squeezes the gas in the second air pressure frame 51. As the piston plate 52 continues to move, the gas pressure in the second air pressure frame 51 will increase.

[0060] The blocking assembly 5 also includes a spring push rod 55 that is slidably connected to the inner wall of the gas pipe 2 53. A Z-shaped blocking plate 56 is fixedly connected to the top of the spring push rod 55. The outer wall of the Z-shaped blocking plate 56 is slidably connected to the inner wall of the rotating ring 45. A fixing frame 57 is fixedly connected to the top of the Z-shaped blocking plate 56.

[0061] A spring inclined block 571 is slidably connected to the inner wall of the fixed frame 57, and a spring snap rod 572 is slidably connected to the inner wall of the fixed frame 57. The high-pressure gas will push the spring push rod 55 to rise, which will drive the Z-shaped baffle plate 56 to rise, so that the Z-shaped baffle plate 56 is close to the gas blocking pipe 47, and the Z-shaped baffle plate 56 blocks the gas blocking pipe 47. When the spring inclined ring 48 descends, the high-pressure gas in the gas delivery pipe 44 can only enter the connecting groove 451 through the groove on the Z-shaped baffle plate 56.

[0062] The blocking assembly 5 also includes a sloping panel 573 fixedly connected to the top of the second gas pipe 53, an outlet pipe 58 fixedly connected to the inner wall of the rotating ring 45, and a spring blocking rod 581 slidably connected to the side wall of the rotating ring 45.

[0063] A fixed rod 582 is fixedly connected to the side wall of the rotating ring 45. The outer wall of the spring blocking rod 581 is slidably connected to the inner wall of the air outlet pipe 58. When the Z-shaped baffle plate 56 rises, it will drive the fixed frame 57 and the spring inclined block 571 to rise, so that the inclined surface of the spring inclined block 571 squeezes the spring blocking rod 581 to move, so that the spring blocking rod 581 enters the air outlet pipe 58, thereby blocking the air outlet pipe 58. As the spring inclined block 571 continues to move, the spring inclined block 571 will contact the fixed rod 582, blocking the spring inclined block 571 and stopping its movement. The fixed frame 57 continues to move and will squeeze the spring at the bottom of the spring inclined block 571, so that it accumulates rebound force. During the continuous movement of the fixed frame 57, it will also drive the spring locking rod 572 to rise.

[0064] 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.

[0065] The method for using the thread-machining equipment for the valve components of this fire extinguisher includes the following steps:

[0066] S1: Workpiece placement: The worker opens the protective door on the outer casing 1 and then places the fire extinguisher valve 23 to be processed on the placement rack 24;

[0067] S2: Start the equipment: Start the motor 22 to drive the thread rolling wheel 21 to rotate, and then start the electric telescopic rod 13 to push the sliding block 12 towards the fire extinguisher valve 23, so that the thread rolling wheel 21 is close to the fire extinguisher valve 23;

[0068] S3: Workpiece clamping: During the continuous movement of the sliding block 12 located on the front, the inclined surface of the inclined block 33 will be driven to contact the push frame 34, squeezing the push frame 34 and causing the push frame 34 to move towards the placement frame 24, so that the push frame 34 contacts the spring sliding frame 35 and pushes the spring sliding frame 35 to move.

[0069] A specific application of this embodiment is as follows: When using this invention, the operator opens the protective door on the outer casing 1, then places the fire extinguisher valve 23 to be processed on the placement rack 24, closes the protective door, starts the motor 22 to drive the thread rolling wheel 21 to rotate, and then starts the electric telescopic rod 13 to push the sliding block 12 towards the fire extinguisher valve 23, so that the thread rolling wheel 21 is close to the fire extinguisher valve 23. During the continuous movement of the sliding block 12 located on the front, it will drive the inclined surface of the inclined block 33 to contact the push frame 34, squeezing the push frame 34 and causing the push frame 34 to move towards the placement rack 24, so that the push frame 34 contacts the spring sliding frame 35, pushing the spring sliding frame 35 to move, allowing the spring sliding frame 35 to accumulate rebound force. When the spring sliding frame 35 moves, it will push the connecting rod 361 to rotate, causing the connecting rod 361 to fold, pushing the arc-shaped block 36 towards the inner wall of the fire extinguisher valve 23, driving the arc-shaped expansion bladder 38 to move. At the same time, When the spring sliding frame 35 moves, it also drives the compression ring 371 to move, compressing the gas in the air cylinder 37. The compressed gas enters the arc-shaped expansion bladder 38 through the telescopic tube 372, causing the arc-shaped expansion bladder 38 to inflate and expand initially until the inclined surface of the inclined block 33 separates from the push frame 34. The arc-shaped expansion bladder 38 then contacts the inner wall of the fire extinguisher valve 23, flexibly clamping the fire extinguisher valve 23. The sliding block 12 continues to move until the thread rolling wheel 21 contacts the fire extinguisher valve 23, compressing the fire extinguisher valve 23. Through the rotation of the thread rolling wheel 21, the fire extinguisher valve 23 is driven to rotate, performing thread processing on the fire extinguisher valve 23. By flexibly clamping the fire extinguisher valve 23, a supporting force is applied evenly, reducing the impact of the center of gravity shift on the fire extinguisher valve 23 during rotation. This effectively prevents the irregular shape of the fire extinguisher valve 23 from causing shaking during rotation, ensuring the stability of its rotation process.

[0070] Secondly, when the pusher 34 moves towards the fire extinguisher valve 23, it also moves the connecting rod 421, causing it to rotate and push the piston plate 42 to rise, compressing the gas in the gas pressure frame 41. The compressed gas enters the rotating ring 45 through the gas supply pipe 44. At this time, the gas is blocked by the spring inclined ring 48, thus generating high pressure. When the fire extinguisher valve 23 rotates, the supporting force of the arc-shaped expansion bladder 38 on the fire extinguisher valve 23 will drive the arc-shaped expansion bladder 38 to rotate, thereby driving the rotating rod 32 to rotate, causing the protrusion 46 to rotate. When the protrusion 46 rotates and contacts the spring inclined ring 48, it will compress the spring inclined ring 48 to descend, separating the spring inclined ring 48 from the inclined surface in the gas blocking pipe 47, thus removing the obstruction of the gas. At this time, the high-pressure gas will enter the connecting groove 451 through the gas blocking pipe 47, enter the air pressure cylinder 37 through the connecting groove 451, and finally enter the arc-shaped expansion bladder 38, causing the arc-shaped expansion bladder 38 to expand again. When the protrusion 46 separates from the spring inclined ring 48, the rebound force of the spring inclined ring 48 will be released, allowing the spring inclined ring 48 to return to its original position and block the gas again. This process repeats, and as the thread rolling wheel 21 gradually squeezes the fire extinguisher valve 23, the expansion amplitude of the arc-shaped expansion bladder 38 gradually increases, so that the supporting force of the arc-shaped expansion bladder 38 matches the changing squeezing force of the thread rolling wheel 21, effectively balancing the squeezing force of the thread rolling wheel 21, and effectively preventing the squeezing force of the thread rolling wheel 21 from gradually increasing, resulting in insufficient supporting force of the flexible clamp, which could easily lead to deformation of the fire extinguisher valve 23.

[0071] Secondly, when piston plate 42 rises, it drives connecting rod 43 to rise, which in turn drives piston plate 52 to rise. Piston plate 52 then compresses the gas inside pressure frame 51. As piston plate 52 continues to move, the gas pressure inside pressure frame 51 increases. This high-pressure gas then pushes spring push rod 55 upward, causing Z-shaped baffle plate 56 to rise and approach the gas-blocking pipe 47, thus blocking it. When spring inclined ring 48 descends, the high-pressure gas in gas pipe 44 can only enter the connecting groove 451 through the groove on Z-shaped baffle plate 56. After some gas in pressure frame 41 enters the connecting groove 451, the gas pressure inside pressure frame 41 decreases. The gas in the second gas supply pipe 53 will enter the first gas pressure frame 41 through the inlet pipe 54 and the inlet one-way valve 541. At this time, the gas pressure in the second gas supply pipe 53 will decrease, the pushing force on the spring push rod 55 will decrease, and the rebound force of the spring push rod 55 will be released, causing it to drop and increasing the gap between the Z-shaped baffle plate 56 and the fixed frame 57, allowing more gas to flow in. This effectively prevents the high-pressure gas in the first gas pressure frame 41 from quickly entering the arc-shaped expansion bladder 38 when the pressure is too high, causing it to expand too much initially. After the gas pressure in the arc-shaped expansion bladder 38 increases, the gas pressure in the first gas pressure frame 41 will decrease, making it difficult for subsequent gas to enter the connecting groove 451 again, affecting the expansion range of the arc-shaped expansion bladder 38 to match the extrusion force of the thread rolling wheel 21.

[0072] Secondly, when the Z-shaped baffle plate 56 rises, it will drive the fixed frame 57 and the spring inclined block 571 to rise, causing the inclined surface of the spring inclined block 571 to press against the spring blocking rod 581 and move it. This allows the spring blocking rod 581 to enter the vent pipe 58, thereby blocking the vent pipe 58. As the spring inclined block 571 continues to move, it will come into contact with the fixed rod 582, blocking the spring inclined block 571 and stopping its movement. The fixed frame 57 then... Continuing to move the frame will compress the spring at the bottom of the spring ramp block 571, causing it to accumulate rebound force. During the continuous movement of the fixed frame 57, it will also cause the spring latch rod 572 to rise. When the spring latch rod 572 moves to the notch position of the spring ramp block 571, since it was previously in a stretched state, its rebound force will be released, allowing it to insert into the spring ramp block 571 and fix it in place. At this time, the Z-shaped blocking plate... 56 will block the gas-blocking tube 47. After the thread machining on the fire extinguisher valve 23 is completed, the electric telescopic rod 13 will retract, causing the thread rolling wheel 21 to separate from the fire extinguisher valve 23. At this time, because the gas in the second gas pressure frame 51 is injected into the first gas pressure frame 41, the gas pressure in the second gas pressure frame 51 is low, and the pushing force on the spring push rod 55 is low. Therefore, the Z-shaped blocking plate 56 and the fixed frame 57 will descend. Because the spring inclined block 571 is stuck, the fixed frame 57 descends. The spring inclined block 571 descends and separates from the spring blocking rod 581. The rebound force of the spring blocking rod 581 is released, causing the spring blocking rod 581 to separate from the gas outlet pipe 58. At this time, the high-pressure gas in the connecting groove 451 will be discharged through the gas outlet pipe 58, reducing the expansion amplitude of the arc-shaped expansion bladder 38 and effectively preventing the thread rolling wheel 21 from separating from the fire extinguisher valve 23. The arc-shaped expansion bladder 38 continues to exert a large squeezing force on the fire extinguisher valve 23, which can easily lead to deformation of the fire extinguisher valve 23.

[0073] When the sliding block 12 causes the inclined block 33 to separate from the push frame 34, the rebound force of the spring sliding frame 35 is released, causing the push frame 34 to return to its original position. This causes the piston plate 42 and piston plate 52 to descend, allowing the air hole 511 of the pneumatic frame 51 to reconnect with the top of the piston plate 52, replenishing the gas inside the pneumatic frame 51. At the same time, as the piston plate 52 returns to its original position, the gas pushing force on the spring push rod 55 disappears, causing its rebound force to be released and return to its original position. This causes the Z-shaped blocking plate 56 and the fixed frame 57 to return to their original positions, allowing the spring locking rod 572 to contact the inclined surface of the inclined plate 573. The spring locking rod 572 is then compressed and placed in a stretched state, separating from the spring inclined block 571. The rebound force of the spring inclined block 571 is then released, causing it to return to its original position.
