Description

Technical Field

[0001] This application relates to the field of spinning forming technology, and in particular to an integrated spinning forming equipment and forming process for an air storage cylinder. Background Technology

[0002] As a key component of automotive braking systems, air reservoirs are mainly used in the air circuit systems of commercial vehicles such as trucks and buses. Their core function is to store compressed gas generated by the air compressor, providing a stable air source for subsystems such as braking and horn, and playing an important role in automotive braking systems.

[0003] Currently, gas storage cylinders are mainly processed using two methods: cap welding and spinning. The cap welding process involves extruding a metal tube to form a pipe body, and then welding end caps to both ends of the pipe body to form a gas storage cylinder. The spinning process involves clamping a metal tube blank in a spinning machine and rotating the metal tube. The metal tube blank is heated, and pressure is applied to the rotating metal tube by a spinning wheel. The spinning wheel is fed axially and causes local plastic deformation of the metal tube, thereby forming a gas storage cylinder.

[0004] In existing spinning forming technology, during the gradual shrinkage process of spinning, the spinning wheel applies pressure to the outside of the metal tube, and the material undergoes plastic deformation in both the radial and axial directions. However, the lack of effective internal support causes stepped wrinkles to form on the inner wall of the metal tube. The wrinkles on the outer wall of the metal tube can be smoothed by replacing spinning wheels of different specifications or by reducing the moving speed of the spinning wheels. However, the lack of effective internal support makes it difficult to eliminate the wrinkles on the inner wall of the metal tube. After spinning forming, the metal tube is prone to stress concentration on its inner wall and cracks, affecting the product's safety performance and service life. Summary of the Invention

[0005] In order to improve the problem that the lack of internal support during the spinning process of the gas storage cylinder in the prior art leads to stress concentration and cracking on the inner wall of the gas storage cylinder, this application provides an integrated spinning forming equipment and forming process for the gas storage cylinder.

[0006] The technical solution provided in this application for an integrated spinning forming equipment and forming process for a gas storage cylinder is as follows: An integrated spinning forming equipment and forming process for an air storage cylinder includes a machine body, on which spinning wheels are symmetrically and slidably arranged, and a controller is provided on the machine body. The machine body is characterized by: a clamping disc rotatably arranged on the machine body, a metal tube disposed on the clamping disc, a drive plate disposed on the machine body, the drive plate passing through the clamping disc, a support component for supporting the interior of the metal tube disposed on the drive plate, and a detection component for detecting wrinkles inside the metal tube disposed on the drive plate. The support assembly includes support spheres symmetrically arranged on both sides of the drive plate. The support spheres are movably fitted against the inner wall of the metal tube. The machine body is provided with a drive component for driving the support spheres to move. The detection assembly includes a detection probe elastically disposed on the drive plate, the detection probe being movably attached to the inner wall of the metal tube, and a moving part for driving the detection probe to move on the body. The detection assembly also includes smoothing parts disposed on both sides of the drive plate.

[0007] By adopting the above technical solution, when spinning the metal tube, the clamping plate clamps and fixes the metal tube, the clamping plate rotates and drives the metal tube to rotate, the spinning wheels located on both sides of the outer wall of the metal tube move and abut against the outer wall of the metal tube, the spinning wheels apply spinning force to the metal tube, so that the metal tube gradually narrows and forms a bowl-shaped bottle bottom or bottle top.

[0008] While the spinning rollers apply spinning pressure to the outer wall of the metal tube, the driving component drives the driving plate to move, thereby moving the support ball and changing the angle of the support ball. This ensures that the support ball aligns with the spinning rollers on the outside of the metal tube, allowing the support ball on the driving plate to fit against the inner wall of the metal tube, providing support and effectively reducing the step-like wrinkles that form inside the metal tube during the spinning process.

[0009] Since both the spinning wheel and the support ball exert spinning pressure on the wall of the metal tube, the walls of the metal tube located on both sides of the support ball are easily squeezed and form protrusions during the spinning process. The moving part drives the detection probe to fit against the inner wall of the metal tube, identify the protrusions on the metal tube wall after the support ball has spun, and make the smoothing ball smooth the protrusions on the inner wall of the metal tube. This reduces the formation of wrinkles and protrusions on the inner wall of the metal tube during the spinning process, reduces stress concentration inside the metal tube, and effectively improves the safety performance and service life of the product.

[0010] Optionally, the driving component includes a first support rod, a first adjusting rod, a sliding plate, a first cylinder, and a second cylinder. One end of the first support rod is rotatably mounted on the driving plate, and the supporting ball is rotatably mounted on the other end of the first support rod. One end of the first adjusting rod is slidably mounted on the driving plate, and the other end of the first adjusting rod is rotatably mounted on the first support rod. One end of the sliding plate is mounted on the first adjusting rod. The telescopic end of the first cylinder is mounted on the end of the driving plate, and the telescopic end of the second cylinder is mounted on the end of the sliding plate.

[0011] By adopting the above technical solution, since the bottom and top openings of the gas storage cylinder are both elliptical bowl-shaped structures, activating the first cylinder moves the drive plate along the length of the machine body and moves the first support rod, causing a change in the position of the first support rod on the drive plate. Activating the second cylinder moves the sliding plate along the length of the machine body and moves the first adjusting plate on the drive plate. The movement of the first adjusting plate causes the first support rod to rotate at a certain angle, thus bringing the support ball into contact with the inner wall of the metal tube. A stable triangular structure is formed between the first support rod, the first adjusting rod, and the drive plate, providing stable spinning force to the inner wall of the metal tube during the spinning process. Compared to fixing the internal support mold on the clamping plate, the ability of the first support rod and the second adjusting rod to move on the drive plate facilitates spinning of metal tubes of different diameters and improves spinning efficiency.

[0012] Optionally, the moving component includes a second support rod, a second adjusting rod, a moving plate, a receiving plate, a third cylinder, and a fourth cylinder. One end of the second support rod is rotatably mounted on the moving plate, and the detection probe is mounted on the other end of the second support rod. One end of the second adjusting rod is slidably mounted on the moving plate, and the other end of the second adjusting rod is rotatably mounted on the second support rod. One end of the receiving plate is mounted on the second adjusting rod. The telescopic end of the third cylinder is mounted on the end of the moving plate, and the telescopic end of the fourth cylinder is mounted on the end of the receiving plate.

[0013] By adopting the above technical solution, during the spinning process of the metal tube, the spinning force needs to be applied back and forth to the metal tube, causing the end of the metal tube to gradually narrow into an elliptical bowl-shaped structure. When the spinning wheel moves towards the rotation axis of the clamping plate, the third cylinder is activated. The third cylinder extends and drives the moving plate to move. The moving plate drives the second support rod to move. The fourth cylinder is activated. The fourth cylinder moves and drives the receiving plate to move. The receiving plate drives the second adjusting plate to move on the moving plate. The second adjusting rod moves and rotates the first support rod by a certain angle, so that the detection probe abuts against the inner wall of the metal tube. At this time, the first support rod deflects by a certain angle, and the detection probe is positioned above the support ball. When the spinning wheel moves away from the rotation axis of the clamping plate, the detection probe is positioned below the support ball, so that the detection probe can detect the metal tube wall after spinning by the spinning wheel and the support ball.

[0014] When the detection probe detects a protrusion on the metal pipe wall after the spinning wheel and support ball have spun, the adjusting component moves the smoothing ball on the second support rod and abuts against the protrusion on the metal pipe wall, thereby smoothing the protrusion and reducing wrinkles on the inner wall of the metal pipe during the spinning process. This effectively improves the safety performance and service life of the gas storage cylinder.

[0015] Optionally, the smoothing component includes a smoothing ball rotatably mounted on the second support rod, a connecting rod slidably mounted on the second support rod, the smoothing ball rotatably mounted at the end of the connecting rod, and an adjusting component for moving the smoothing ball on the second support rod.

[0016] By adopting the above technical solution, when the detection probe detects a protrusion on the inner wall of the metal tube, the adjusting component drives the connecting rod to move and makes the smoothing ball abut against the inner wall of the metal tube, so as to spin and smooth the protrusion on the inner wall of the metal tube, further improving the flatness of the inner wall of the metal tube, reducing the occurrence of cracks in the gas storage cylinder during use, and improving the safety performance and service life of the gas storage cylinder.

[0017] Optionally, the adjusting component includes an electric push rod mounted on the second support rod, the telescopic end of the electric push rod being mounted on the connecting plate, a pressure sensor being mounted on the second support rod, the pressure sensor being movably fitted with the detection probe, and the pressure sensor being electrically connected to the controller.

[0018] By adopting the above technical solution, when the detection probe detects a protrusion on the inner wall of the metal tube, the detection probe is compressed, and the pressure sensor is pressed. The pressure sensor transmits a signal to the controller, which controls the electric push rod to start. The electric push rod connecting rod moves a certain distance and makes the smoothing ball fit against the inner wall of the metal tube, thereby smoothing the protruding part of the inner wall of the metal tube. This further reduces the flatness inside the metal tube, reduces the stress concentration in the gas storage cylinder after spinning, and improves the safety performance and service life of the gas storage cylinder.

[0019] Optionally, both the movable plate and the drive plate are slidably provided with sliders, and the first adjusting rod and the second adjusting rod are rotatably mounted on the sliders. The sliders are provided with fixing grooves, and the sliders are slidably and elastically provided with locking pins. The ends of the sliding plate and the receiving plate are provided with fixing rods, and the fixing rods are provided with locking grooves. The locking pins are inserted into and adapted to the locking grooves, and the fixing rods are inserted into and adapted to the fixing grooves. Both the drive plate and the movable plate are provided with unlocking magnetic blocks.

[0020] By adopting the above technical solution, before spinning the metal tube, the metal tube is fixed on the clamping plate. The second and fourth cylinders are activated, causing the fixing rods on the sliding plate and receiving plate to extend into the fixing grooves. Simultaneously, the unlocking magnet is energized, generating a magnetic force on the locking pin, causing it to move away from the fixing pin. The fixing pin then inserts into the fixing groove. The unlocking magnet is de-energized, and the locking pin inserts into the locking groove, thus fixing the sliding plate and fixing plate to the two sliders respectively. Because an opening is provided at the top of the air tank, the fixing pin can remain fixed to the sliders during the spinning process at the top of the air tank. After the spinning is completed, the second and fourth cylinders drive the slider to move to the position of the unlocking magnetic block and unlock the fixed column. Then, the sliding plate and the receiving plate are moved to the outside of the metal tube. The sliding plate and the receiving plate support the opening of the metal tube and improve the flatness of the bend of the opening of the metal tube. During the spinning process of the bottom of the air storage cylinder, after the metal tube is spun and closed to a certain extent, the second and fourth cylinders first push the slider to move to the unlocking magnetic block to unlock it, then move the sliding plate and the receiving plate to the outside of the metal tube, and finally the spinning wheel seals the metal tube.

[0021] Optionally, a paint tank is provided on the second support rod, and an electric spray head is provided on the paint tank. The electric spray head is electrically connected to the pressure sensor.

[0022] By adopting the above technical solution, when the detection probe detects a protrusion inside the metal tube, the pressure sensor transmits a signal to the controller. The controller then controls the electric nozzle to open and sprays the paint from the paint tank onto the protruding part inside the metal tube to complete the marking. After the marking is completed, technicians can focus on checking the marking position, which facilitates subsequent technicians to further check the flatness of the inner wall of the gas storage tank.

[0023] Optionally, a gantry frame is slidably mounted on the machine body, and the sliding plate and the receiving plate are slidably mounted on the gantry frame.

[0024] By adopting the above technical solution, when spinning metal tubes of different lengths, the position of the gantry on the machine body is adjusted so that the receiving plate and the sliding plate are located inside the metal tube, which facilitates the spinning process of metal tubes of different lengths and improves the practicality of the device.

[0025] Optionally, the machine body is provided with a drive motor, the clamping plate is fixedly connected with a gear ring, the output end of the drive motor is provided with a gear that meshes with the gear ring, the machine body is provided with a guide rail, a spinning plate is slidably arranged on the guide rail, and the spinning wheels are symmetrically and slidably arranged on the spinning plate.

[0026] By adopting the above technical solution, the drive motor drives the gear to rotate, the gear meshes with the gear ring, and drives the clamping plate to rotate, thereby driving the metal tube to rotate; the spinning plate slides along the guide rail and drives the spinning wheel to move along the length of the machine body, and the spinning wheel moves on the spinning plate along the width of the machine body, thereby causing the spinning wheel to spin the outer wall of the metal tube.

[0027] A spinning process for an integrated gas storage cylinder includes the following steps: S1: Fix the metal tube on the clamping plate, drive the motor to rotate the clamping plate, and apply spinning force to the metal tube with the spinning wheel to gradually close the end of the metal tube. S2: The driving component drives the support ball to support the inside of the metal tube. The support ball corresponds to the external spinning wheel, reducing wrinkles on the inner wall of the metal tube. S3: The moving part drives the detection probe to detect the wrinkles inside the metal tube. If the detection probe detects wrinkles inside the metal tube, the adjusting part drives the smoothing ball to move and abut against the inner wall of the metal tube. The smoothing ball smooths the wrinkles on the inner wall of the metal tube. If the detection probe does not detect wrinkles inside the metal tube, the smoothing ball and the second support rod remain stationary and the smoothing ball separates from the inner wall of the metal tube. S4: S1, S2, and S3 are performed simultaneously. The supporting ball and the spinning wheel correspond to each other to reduce wrinkles on the inner wall of the metal tube. The detection probe detects the part after the supporting ball has been spun, and at the same time, the smoothing ball is activated to smooth the wrinkled parts.

[0028] S5: If an opening is required in the metal tube, the sliding plate and the receiving plate can be placed inside the metal tube. If no opening is required in the metal tube, the second and fourth cylinders push the sliding plate and the receiving plate, and move the slider to the unlocking magnetic block, so that the fixing rod is separated from the slider, and the sliding plate and the receiving plate are moved to the outside of the metal tube. The external spinning roller closes the metal tube.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. When spinning the metal tube, the first and second cylinders are activated, which drive the first support rod and the first adjusting rod to move, so that the support ball on the first support rod abuts against the inner wall of the metal tube and the support ball corresponds to the spinning wheel outside the metal tube. The support ball and the spinning wheel abut against the inner and outer walls of the metal tube respectively, which reduces the wrinkles on the inner wall of the metal tube during the spinning process and reduces the stress concentration on the inner wall of the metal tube after spinning, thus improving the safety performance and service life of the gas storage cylinder. 2. When spinning the metal tube, the third and fourth cylinders are activated, driving the second support rod and the second adjusting rod to move. This causes the detection probe on the second support rod to abut against the inner wall of the metal tube, detecting any protrusions on the inner wall of the metal tube after spinning by the support ball and the spinning wheel. If protrusions are present, the electric push rod is activated, causing the smoothing ball on the connecting rod to abut against the metal tube. Under the combined action of the spinning wheel, the support ball, and the smoothing ball, the flatness of the inner wall of the metal tube can be ensured, further improving the safety performance and service life of the gas storage cylinder. 3. By adjusting the positions of the first support rod, the first adjusting rod, the second support rod, and the second adjusting rod, metal tubes of different diameters can be spun. By unlocking the sliding rod and the receiving rod, the same equipment can both seal the metal tube to form the bottom of the tube and leave an opening in the metal tube to form the top of the tube, thus meeting different processing requirements for metal tubes and improving the practicality of the device.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses an integrated spinning forming apparatus for a gas storage cylinder. (Refer to...) Figure 1-4 The integrated spinning forming equipment for gas storage cylinders includes a machine body 1, on which a controller and display screen are installed. The controller is a microcontroller, a programmable logic controller, and an intelligent pressure sensor 442, etc. A clamping plate 12 is rotatably mounted on the machine body 1, and clamping claws are rotatably mounted on the clamping plate 12. A drive motor 13 is fixedly connected inside the machine body 1, and a gear 14 is coaxially fixedly connected to the output end of the drive motor 13. A gear ring 15 that meshes with the gear 14 is integrally formed on the clamping plate 12. The clamping plate 12 is a hollow circular disc. The machine body 1 has a metal tube and a clamping disc 12 with its rotation axis parallel to the length of the machine body 1. The machine body 1 is equipped with a guide rail 16 and a spinning plate 17 is slidably mounted on the guide rail 16. The machine body 1 is equipped with a drag chain connected to the spinning plate 17. The machine body 1 is equipped with a linear motor. The spinning plate 17 is symmetrically and slidably mounted with mounting plates. The moving direction of the mounting plates is parallel to the width of the machine body 1. The spinning wheel 11 is rotatably mounted on the mounting plate. The mounting plate is equipped with a heating tube for heating the metal tube. A double-headed cylinder can be installed between the two mounting plates for driving.

[0035] A drive plate 2 is slidably mounted on the machine body 1. The drive plate 2 is located on the side of the clamping plate 12 away from the spinning plate 17. The drive plate 2 passes through the clamping plate 12. A support assembly for supporting the inner wall of the metal tube is provided on the drive plate 2. The support assembly includes support balls 31 symmetrically arranged on the drive plate 2. Each support ball 31 corresponds to a spinning wheel 11. A drive component for driving the support balls 31 to move is provided on the machine body 1.

[0036] The body 1 is equipped with a detection component for detecting protrusions inside the metal tube. The detection component includes a detection probe 41 mounted on the drive plate 2. The body 1 is equipped with a moving part for driving the detection probe 41 to move. The detection component also includes a smoothing part 43 for smoothing out the protrusions inside the metal tube.

[0037] When spinning the metal tube, the drive plate 2 located inside the metal tube and the corresponding connecting cable can pass through the middle of the annular clamping plate 12, and the corresponding signal or cable can also be transmitted through the clamping plate 12. The metal tube is clamped and fixed on the clamping plate 12. The drive motor 13 drives the gear 14 to rotate. The gear 14 meshes with the gear ring 15 and drives the clamping plate 12 to rotate. The heating tube sprays high-temperature flames to heat the metal tube. At the same time, the linear motor drives the drag chain to move and moves the spinning plate 17 along the length of the machine body 1. The double-headed cylinder drives the mounting plate to move towards each other along the width of the machine body 1, so that the two spinning wheels 11 abut against the two sides of the metal tube. The rotating metal tube drives the spinning wheels 11 to rotate, so that the two spinning wheels 11 spin the two sides of the metal tube.

[0038] Simultaneously, the driving component drives the driving plate 2 to move, causing the support ball 31 located inside the metal tube to move, and making the movement trajectory of the support ball 31 correspond to the movement trajectory of the spinning wheel 11. The support ball 31 provides support force to the inner wall of the metal tube. The spinning wheel 11 and the support ball 31 spin the outer wall and inner wall of the metal tube respectively. Compared with the prior art, which only spins the outer wall of the metal tube, the support ball 31 inside the metal tube effectively improves the flatness of the inner wall of the metal tube, reduces the cracks generated during the use of the gas storage cylinder, and effectively improves the safety performance and service life of the gas storage cylinder.

[0039] During the spinning process of the supported ball 31 and the spinning wheel 11 on the heated metal tube, the inner and outer walls of the metal tube are prone to forming raised indentations and burrs under the pressure of the supported ball 31 and the spinning wheel 11. In the prior art, the problems of stepped wrinkles and burrs on the outer wall of the metal tube can be eliminated by replacing the spinning wheel 11 with a different specification, or by using a lathe tool to machine-pin the wrinkles on the outer wall of the metal tube while spinning the metal tube to close the end. During the spinning process, the moving part simultaneously drives the detection probe 41 to abut against the inner wall of the metal tube. The detection probe 41 identifies the protrusions on the inner wall of the metal tube and smooths the protrusions on the inner wall of the metal tube by the smoothing part 43, which further improves the flatness of the inside of the metal tube and improves the safety performance and service life of the gas storage cylinder.

[0040] Reference Figure 1 , Figure 2 and Figure 4The driving component includes a first support rod 321 rotatably mounted on the drive plate 2, a support ball 31 rotatably mounted at the end of the first support rod 321 away from the drive plate 2, a first adjusting rod 322 slidably mounted on the drive plate 2, the end of the first adjusting rod 322 away from the drive plate 2 rotatably mounted on the first support rod 321, a first cylinder 323 mounted on the body 1, the telescopic end of the first cylinder 323 fixedly connected to the end of the drive plate 2, a sliding plate 325 slidably mounted on the body 1, the end of the sliding plate 325 being located at the end of the first adjusting rod 322 near the drive plate 2, and a second cylinder 324 mounted on the body 1, the telescopic end of the second cylinder 324 fixedly connected to the end of the sliding plate 325 away from the metal tube.

[0042] Reference Figure 4 and Figure 6The smoothing component 43 includes a connecting plate slidably mounted on the second support rod 423. The second support rod has a connecting groove, and the connecting plate is slidably mounted in the connecting groove. The smoothing ball 431 is rotatably mounted at the end of the connecting plate away from the second support rod 423. An adjusting component for adjusting the movement of the smoothing ball 431 is provided on the second support rod 423. The adjusting component includes an electric push rod 441 disposed in the connecting groove. A pressure sensor 442 is disposed between the detection cylinder and the spring. The pressure sensor 442 is electrically connected to the controller. The pressure sensor 442 can be a MEMS high-temperature pressure sensor 442, a ceramic pressure sensor 442, etc. The pressure sensor 442 is located in the connecting groove and the detection cylinder. All parts are equipped with heat insulation coatings or filled with heat insulation boards such as polyurethane boards, extruded polystyrene boards, and rock wool boards. Since the indentation protrusion formed by the support wheel and the spinning wheel 11 during the spinning process of the heated metal tube is relatively small, the power provided by the electric push rod 441 is sufficient to provide the corresponding support force. The electric push rod 441 can also be replaced by other cylinders, oil cylinders, etc. A paint tank 61 is fixedly attached to the side of the second support rod 423 away from the detection probe. The paint tank 61 is filled with organosilicon high-temperature resistant paint, inorganic silicate paint, inorganic high-temperature grade paint, etc. An electric nozzle 62 is fixedly attached to the paint tank 61, and the electric nozzle 62 is electrically connected to the controller.

[0043] Reference Figure 4 and Figure 5 Both the drive plate 2 and the moving plate 421 have sliding grooves, and sliders 5 are slidably arranged in the sliding grooves. The first adjusting rod 322 and the second adjusting rod 424 are respectively rotatably arranged on the two sliders 5. The sliders 5 have fixing grooves 51.

The receiving plate 422 is provided with a sliding groove. The sliding plate 325 is integrally formed with a sliding rail, which is slidably adapted to the sliding groove.

[0044] When the metal tube is spun, before the metal tube is fixed on the clamping plate 12, the fixing rod 53 on the sliding plate 325 and the receiving plate 422 is separated from the slider 5. The unlocking magnet 55 attracts the slider 5 and causes the locking pin 54 to retract into the locking groove 52. When the metal tube is fixed on the clamping plate 12, the second cylinder 324 and the fourth cylinder 426 are started and drive the sliding plate 325 and the receiving plate 422 to move, so that the fixing rod 53 is inserted into the fixing groove 51 of the slider 5. The ends of the sliding plate 325 and the receiving plate 422 abut against the slider 5. The unlocking magnet 55 is de-energized, and the locking pin 54 is inserted into the locking groove 52 on the fixing rod 53. The fixing rod 53 is fixed to the slider 5.

[0045] The clamping plate 12 drives the metal tube to rotate, the first cylinder 323 and the second cylinder 324 are activated. The first cylinder 323 drives the drive plate 2 to move along the length of the machine body 1 and drives the first adjusting rod 322 to move. The second cylinder 324 is activated and drives the slider 5 to move. The slider 5 drives the first adjusting rod 322 to move on the drive plate 2, so that the support ball 31 located on the first support rod 321 corresponds to the movement trajectory of the spinning wheel 11. The spinning wheel 11 and the support ball 31 spin the outer wall and the inner wall of the metal tube respectively. A triangular stable structure is formed between the first support rod 321, the first adjusting rod 322 and the drive plate 2, so that the support ball 31 provides stable support force to the inner wall of the metal tube during the spinning process. Compared with the prior art, only the spinning wheel 11 spins the outer wall of the metal tube, and the support ball 31 provides support force to the inner wall of the metal tube, which reduces the formation of stepped wrinkles on the inner wall of the metal tube and reduces the formation of cracks on the inner wall of the air storage cylinder after spinning, thus improving the safety performance and service life of the air storage cylinder.

[0046] During the spinning process of the metal tube, the third cylinder 425 and the fourth cylinder 426 are activated simultaneously. The third cylinder 425 drives the moving plate 421 to move along the length of the machine body 1, adjusting the position of the second support rod 423 on the moving plate 421. The fourth cylinder 426 drives the receiving plate 422 to move along the length of the machine body 1 and pushes the slider 5 on the moving plate 421 to move, adjusting the position of the second adjusting rod 424 on the moving plate 421 and changing the angle between the second support rod 423 and the moving plate 421, so that the detection probe 41 is in contact with the inner wall of the metal tube during the spinning process. The second support rod 423, the second adjusting rod 424 and the moving plate 421 form a triangular stable structure, so that the detection probe 41 remains stable when detecting the inner wall of the metal tube.

[0047] During the spinning process of the metal tube, the spinning wheel 11 and the support ball 31 spin back and forth on the metal tube wall, causing the metal tube to gradually narrow to an elliptical bowl shape. Therefore, the first support rod 321 and the second support rod 423 maintain a certain angle during the spinning process, so that the detection probe 41 is located after the spinning trajectory of the support ball 31.

[0048] During the spinning process of the support ball 31 and the spinning wheel 11 on the inner and outer walls of the metal tube, respectively, raised indentations are easily formed on both sides of the support ball 31 on the inner wall of the metal tube. When the detection probe 41 detects a protrusion on the inner wall of the metal tube after spinning by the support ball 31, the detection probe 41 slides along the inner wall of the detection cylinder and generates pressure on the pressure sensor 442 inside the detection cylinder. The pressure sensor 442 transmits a signal to the controller, which controls the electric push rod 441 to start. The electric push rod 441 pushes the connecting rod 432 to move in the connecting groove, so that the smoothing ball 431 on the connecting rod 432 abuts against the protrusion on the inner wall of the metal tube. The smoothing sphere 431 smooths the protrusions on the inner wall of the supporting sphere 31, further improving the flatness of the inner wall of the metal tube, reducing the risk of stress concentration at the end of the gas storage cylinder after molding, and improving the safety performance and service life of the gas storage cylinder; if the detection probe 41 does not detect any protrusions on the inner wall of the metal tube, the smoothing sphere 431 will separate from the inner wall of the metal tube.

[0049] At the same time, the pressure sensor 442 transmits the signal to the controller, which controls the electric nozzle 62 to open, so that the paint in the paint tube is sprayed onto the protruding part of the inner wall of the metal tube, which facilitates the subsequent inspection of the inner wall of the air storage tank by technicians.

[0050] Since the gas storage cylinder is divided into top and bottom parts, the top part of the metal tube is formed by spinning, leaving an opening, and the bottom part is sealed. The top and bottom parts are then welded together to form a complete gas storage cylinder. When an opening is required, the fixed column and slider 5 remain fixed. After the cliff is formed, the sliding plate 325 and the receiving plate 422 are pushed to unlock the fixed column. The sliding plate 325 and the receiving plate 422 provide support for the opening, effectively improving the flatness of the opening. After spinning, the sliding plate 325 and the receiving plate 422 are then... The receiving plate 422 moves to the outside of the metal pipe, and a circular sleeve can be fitted onto the sliding plate 325 on the receiving plate 422. The circular sleeve can be fixedly mounted on the gantry 7. Before spinning the metal pipe, a release agent such as boron nitride release agent can be sprayed onto the metal sleeve. When the metal pipe needs to be sealed, the receiving plate 422 and the sliding plate 325 are moved to the outside of the metal pipe, and the external spinning roller 11 spins the outer wall of the metal pipe, while the internal support ball 31 separates from the metal pipe. This device can spin metal pipes in different situations, increasing the practicality of the device.

[0051] The implementation principle of the integrated spinning forming equipment and forming process for the gas storage cylinder in this application embodiment is as follows: during the spinning process of the metal tube, the drive motor 13 drives the clamping plate 12 to rotate, the clamping plate 12 drives the metal tube to rotate, the heating pipe located outside the metal tube heats the metal tube, and the spinning wheel 11 spins the outer wall of the metal tube.

[0052] The first cylinder 323 and the second cylinder 324 are activated. The first cylinder 323 drives the drive plate 2 to move along the length of the machine body 1. The drive plate 2 drives the first support rod 321 to move. The second cylinder 324 drives the sliding plate 325 to move along the length of the machine body 1 and drives the slider 5 on the drive plate 2 to move, so that the first adjusting rod 322 moves on the drive plate 2, thereby adjusting the position and angle of the first support rod 321. This makes the movement trajectory of the support ball 31 on the first support rod 321 correspond to the spinning wheel 11. The spinning wheel 11 and the support ball 31 simultaneously spin the inner and outer walls of the metal tube, reducing the occurrence of stepped wrinkles on the inner wall of the metal tube and reducing the occurrence of cracks during the subsequent use of the gas storage cylinder, thus improving the safety performance and service life of the gas storage cylinder.

[0053] The detection probe 41 on the second support rod 423 detects the inner wall of the metal tube after the support ball 31 has been spun. If there is a protrusion on the inner wall of the metal tube, the detection probe 41 is compressed, which puts pressure on the pressure sensor 442 inside the detection cylinder and causes the electric push rod 441 inside the connecting groove to extend. This causes the connecting rod 432 to push the smoothing ball 431 to move, so that the smoothing ball 431 abuts against the protrusion on the inner wall of the metal tube. The smoothing ball 431 further improves the flatness of the inner wall of the metal tube, effectively improving the safety performance and service life of the gas storage cylinder. At the same time, the controller starts the electric spray head 62, so that the paint inside the paint tank 61 is sprayed onto the inner wall of the metal tube with the protrusion, which facilitates the subsequent inspection of the flatness of the inner wall of the metal tube by technicians. By adjusting the positions of the first support rod 321, the second support rod 423, the first adjusting rod 322 and the second adjusting rod 424, metal tubes of different sizes can be spun, which effectively improves the practicality of the device.

[0054] This embodiment also discloses an integrated spinning forming process for a gas storage cylinder, based on an integrated spinning forming device for a gas storage cylinder, including the following steps: S1: Fix the metal tube on the clamping plate 12, drive the motor 13 to drive the clamping plate 12 to rotate, and the spinning wheel 11 applies spinning force to the metal tube, so that the metal tube gradually closes. S2: The driving component drives the support ball 31 to support the inside of the metal tube. The support ball 31 corresponds to the external spinning wheel 11, reducing the wrinkles on the inner wall of the metal tube. S3: The moving part drives the detection probe 41 to detect the wrinkles inside the metal tube. If the detection probe 41 detects wrinkles inside the metal tube, the adjusting part drives the smoothing ball 431 to move and abut against the inner wall of the metal tube. The smoothing ball 431 smooths the wrinkles on the inner wall of the metal tube. If the detection probe 41 does not detect wrinkles inside the metal tube, the smoothing ball 431 and the second support rod 423 remain stationary, and the smoothing ball 431 separates from the inner wall of the metal tube. S4: S1, S2, and S3 are performed simultaneously. The supporting ball 31 and the spinning wheel 11 correspond to each other to reduce wrinkles on the inner wall of the metal tube. The detection probe 41 detects the part after the supporting ball 31 has been spun, and at the same time, the smoothing ball 431 is activated to smooth the wrinkled parts.

[0055] S5: If an opening is required in the metal tube, the sliding plate 325 and the receiving plate 422 can be placed inside the metal tube. If no opening is required in the metal tube, the second cylinder 324 and the fourth cylinder 426 push the sliding plate 325 and the receiving plate 422, and move the slider 5 to the unlocking magnet 55, so that the fixing rod 53 is separated from the slider 5, and the sliding plate 325 and the receiving plate 422 are moved outside the metal tube. The external spinning roller 11 closes the metal tube.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
