[0002] The main purpose of closing the mouth of a steel cylinder is to process the open end of the steel cylinder to form a specific shape and size to meet the requirements of the subsequent installation of valves, seals and other components. The closed mouth of the steel cylinder is more regular and firm, which can ensure a tight and reliable connection with other components and ensure the safety of the steel cylinder during use. During processing, the steel cylinder port is stamped using a stamping die, and the strong pressure gradually deforms the steel cylinder port to form the required closing shape. This method has high production efficiency and the closing size accuracy is easier to control.

[0003] According to a steel cylinder head forming device with Chinese patent number CN 209830059 U, it includes a roller mechanism for driving the steel cylinder to rotate, and a spinning mechanism and a wheel pressing mechanism for forming the steel cylinder head arranged on both sides of the roller mechanism, wherein the roller mechanism includes a main shaft, a main motor for driving the main shaft to rotate, and a push rod and a chuck located inside the main shaft, the spinning mechanism includes a rotating shaft, a closing die connected to the rotating shaft, and a first power element for driving the rotating shaft to rotate, the wheel pressing mechanism includes a wheel frame, a pressing wheel and a top core connected to the wheel frame, a second power element for driving the wheel frame to move horizontally, and a third power element for driving the wheel frame to move longitudinally; the steel cylinder head forming device can perform one-time forming processing on the bottle head of the steel cylinder, greatly improves the forming efficiency and forming quality of the steel cylinder bottle head, and effectively prevents the mold loss and material loss that may occur in the steel cylinder bottle head forming process.

[0004] The existing technology has the following problems in actual use:

[0005] 1. The existing sealing machines are optimized for cylinders of specific specifications. When cylinders of different diameters need to be produced, it is difficult to adjust them, and even large-scale equipment modification is required;

[0024] 1.

[0042] 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. Specific embodiment one:

[0044] like Figure 1-14 As shown, a multi-station steel cylinder rotary closing machine includes a workbench 1 and a conveyor 2. The conveyor 2 is installed in the middle of the top of the workbench 1. The top rectangular array of the conveyor 2 has a socket 4. The top of the conveyor 2 is plugged with a feeder 6. The bottom of the feeder 6 is provided with a plug post 16. The plug post 16 and the socket 4 are adapted to each other. A proximity sensor 15 is embedded in the middle of the front of the feeder 6. Openings 17 are provided on both sides of the front of the feeder 6 and on the top and bottom. The shape of the opening 17 is an inverted convex shape. The middle of the opening 17 passes through the bottle body 5. The bottom of the opening 17 is provided with a slide rail 20. One side of the top of the opening 17 is provided with a clamping control The end of the clamping controller 19 is electrically connected to a driving motor 23, and the end of the driving motor 23 is transmission-connected to a driving shaft 21. Both sides of the outside of the driving shaft 21 are threadedly connected with moving blocks 25. The top of the moving block 25 is slidably connected to the top of the opening 17. The bottom end of the moving block 25 is threadedly connected to a joint 24. The bottom end of the joint 24 is threadedly connected to a clip 18. An anti-sliding block 22 is provided on the inner side of the clip 18. A pressure sensor is implanted inside the clip 18. The bottom of the clip 18 is slidably connected to a slide rail 20. The clips 18 on both sides clamp the bottle body 5. A total of four groups of openings 17 are opened on the front of the loading piece 6.

[0045] The bottom slide rail 20 of the opening 17 provides guidance for the movement of the clip 18. The top of the moving block 25 is slidably connected to the top of the opening 17 to ensure that the moving block 25 can move smoothly horizontally when the driving shaft 21 rotates. The bottom end of the moving block 25 is threadedly connected to a joint 24, and the bottom end of the joint 24 is threadedly connected to a clip 18. An anti-sliding block 22 is provided on the inner side of the clip 18 to increase the friction between the bottle body 5 and the clamping stability. A pressure sensor is implanted inside the clip 18 to monitor the clamping force in real time to prevent the clamping from being too loose or too tight. The bottom of the clip 18 is slidably connected to the slide rail 20, and the clips 18 on both sides clamp the bottle body 5. A total of four groups of openings 17 are provided on the front of the loading piece 6, which can process multiple bottle bodies 5 at the same time to improve production efficiency.

[0046] In the process of clamping the bottle body 5, the clamping distance of the clamping pieces 18 on both sides is adjusted by the clamping distance adjustment structure composed of the clamping controller 19, the driving motor 23, the driving shaft 21 and the moving block 25. After clamping the bottle body 5, its pressure will be detected in real time. When the pressure exceeds the threshold, the clamping controller 19 will transmit a stop signal, and then the clamping controller 19 will control the driving motor 23 to stop driving. When adjusting the distance, when the driving motor 23 drives the driving shaft 21 to rotate clockwise, the moving blocks 25 on both sides of the outside move inward. When the driving shaft 21 rotates counterclockwise, the moving blocks 25 on both sides of the outside move outward. When the moving block 25 moves, it will drive the clamping piece 18 at the bottom to move. It should be noted that the threads on both sides of the outside of the driving shaft 21 adopt a symmetrical bidirectional thread design, one side is a right-handed thread, and the other side is a left-handed thread.

[0047] In this equipment, after the bottle body 5 to be processed is placed in the loading piece 6 and placed on the conveyor 2, the bottle body 5 can be subjected to flame heating, electromagnetic heating, extrusion molding and cooling treatment in sequence during the forward process. The plug post 16 and the socket 4 are adapted to each other to ensure the stable installation and accurate transmission of the loading piece 6 on the conveyor 2, and the loading piece 6 is not easy to loosen when being conveyed forward. Specific embodiment 2:

[0049] like Figure 1-14 As shown, according to the contents of the specific embodiment one, the following contents are further disclosed: flame heaters 9 are placed on both sides of the front end of the workbench 1, a storage tank 8 is installed inside the flame heater 9, a nozzle 7 is connected to the top of the side of the flame heater 9, and first position sensors 10 are installed on both sides of the top of the workbench 1, and the positions of the first position sensor 10 and the flame heater 9 are aligned.

[0050] In this device, the nozzle 7 at the end of the flame heater 9 is equipped with an automatic spray gun, and the flame is sprayed from top to bottom. The proximity sensor 15 on the front of the loading piece 6 is adapted to the first position sensor 10 and the second position sensor 32. When the conveyor 2 drives the loading piece 6 to move, as the loading piece 6 continues to move forward, the proximity sensor 15 in the middle of the front of the loading piece 6 gradually approaches the first position sensor 10. Once the proximity sensor 15 comes to a position aligned with the front of the first position sensor 10, the first position sensor 10 will quickly sense the presence of the proximity sensor 15. At the same time, the loading piece 6 will also be aligned with the flame heating device. At this time, the high-precision sensing element inside the first position sensor 10 will quickly capture the specific signal emitted by the proximity sensor 15, and transmit the signal to the automatic spray gun of the nozzle 7 at the end of the flame heating wire 9 through the built-in signal transmission chip. After receiving the signal, the automatic spray gun immediately starts the ignition device. The ignition device adopts the existing advanced electronic ignition technology, which can generate high-energy electric sparks in an instant to ignite the combustible gas ejected from the nozzle 7. As the flame ignites, a strong heat flow quickly acts on the bottle body 5 on the feeding piece 6. In this device, the end of the bottle body 5 is heated from top to bottom, that is, the position where the mouth needs to be closed. The size and temperature of the flame can be adjusted according to actual needs.

[0051] It should be noted that the principle of the first position sensor 10 sensing the proximity sensor 15 adopts electromagnetic induction. An electromagnetic induction sensor is implanted in the first position sensor 10, and a coil is provided inside it. When the proximity sensor 15 is close to the position sensor, the coil in the position sensor will sense the change in the magnetic field generated by the proximity sensor 15. This change in the magnetic field will generate an induced current or an induced electromotive force in the coil of the position sensor. The position sensor determines the position of the proximity sensor by detecting the strength and change of this induced signal. For example, when an alternating current of a certain frequency is passed through the coil in the proximity sensor 15, an alternating magnetic field will be generated. This alternating magnetic field will cause electromagnetic induction in the coil of the position sensor, thereby generating a corresponding induced current. The position sensor determines the distance and position of the proximity sensor 15 by analyzing information such as the magnitude and phase of the induced current.

[0052] The principle of sensing the proximity sensor 15 of all position sensors in this device is the same. Specific embodiment three:

[0054] like Figure 1-14 As shown, according to the contents of the specific embodiment 1, the following contents are further disclosed: a first frame plate 11 is welded on both sides of the middle of the top of the workbench 1, and a slide groove 12 is opened on both sides of the top of the workbench 1 near the middle of the conveyor 2, and a heating base 28 is slidably connected in the slide groove 12.

[0055] A first cylinder controller 26 is installed at the bottom of the back side of the first frame plate 11, and the end of the first cylinder controller 26 is electrically connected to the first cylinder assembly 29. The end of the first cylinder assembly 29 is clamped with a heating base 28, and the top of the heating base 28 is clamped with a heating device 27. The components in the heating device 27 are mainly used for electromagnetic heating of the end of the bottle body 5.

[0056] A second position sensor 32 is embedded in the middle of the front of the heating device 27 , and ring openings 33 are formed on both sides, the top and the bottom of the front of the heating device 27 . There are four groups of ring openings 33 .

[0057] The top and bottom of the ring 33 are both threadedly connected with the telescopic column 30, and the end of the telescopic column 30 is threadedly connected with the arc piece 31. An inner groove 34 is opened inside the front of the arc piece 31, and a heating wire is laid in the inner groove 34. The front end of the arc piece 31 is semi-conical and the rear end is semi-cylindrical.

[0058] When the second position sensor 32 in the middle of the front of the heating device 27 senses that the proximity sensor 15 has reached the alignment position, it means that the position of the loading piece 6 is just aligned with the heating device 27. After sensing, the second position sensor 32 in the heating device 27 will transmit a start signal to the first cylinder controller 26 on the back, and then the first cylinder controller 26 will control the first cylinder assembly 29 at the front to extend forward. The extension of the first cylinder assembly 29 will drive the heating base 28 at the front and the heating device 27 at the top to move inward. When the heating device 27 moves forward, the end of the bottle body 5 that is restricted will be inserted between the arc pieces 31 in the circle 33. The upper and lower layers of the arc pieces 31 are initially fitted, which is in line with the heating of the smallest size of the bottle body 5. The entire arc piece 31 structure is retractable through the telescopic column 30 connected at the end. The end of the bottle body 5 with a larger size passes through the arc piece 31 to stretch the upper and lower layers of the arc piece 31.

[0059] During the application process, the first frame plate 11 is welded on both sides of the middle of the top of the workbench 1, providing a stable support structure for the entire heating device. The first frame plate 11 not only physically carries the first cylinder controller 26 and the first cylinder assembly 29, but also ensures the stability and reliability of the heating device during operation. The top of the workbench 1 is provided with a slide groove 12 on both sides near the middle of the conveyor 2, and the design of the slide groove 12 is very exquisite. It provides a precise track for the movement of the heating base 28, so that the heating base 28 can slide smoothly along a predetermined direction under the push of the first cylinder assembly 29. This design ensures the accuracy of the heating device 27 when aligning with the bottle body 5 and performing the heating operation. The heating base 28 is a key component connecting the first cylinder assembly 29 and the heating device 27, and its structural strength and stability are crucial. The clamping method of the heating base 28 and the first cylinder assembly 29 ensures a firm connection between the two, and can withstand the reaction force generated by the heating device 27 during operation. At the same time, the snap-on design of the heating base 28 and the heating device 27 also facilitates quick disassembly and installation when the heating device 27 needs to be maintained or replaced. In the heating device 27, the components used for electromagnetic heating of the end of the bottle body 5 play a core role. These components have been carefully designed and debugged to generate an electromagnetic field of a specific frequency and intensity, so that the end of the bottle body 5 can be quickly heated in a short time to reach the temperature required for the closing process. A second position sensor 32 is embedded in the middle of the front of the heating device 27. The accuracy and response speed of this position sensor are crucial to the entire heating process. It can accurately detect the receiving sensor 15 on the feeding part 6, thereby timely starting the movement and heating operation of the heating device 27. In order to ensure the accuracy of the sensing, the second position sensor 32 usually adopts advanced sensor technology and can work stably in a complex working environment. The two sides of the front side of the heating device 27 and the top and bottom are provided with rings 33. The number and layout of the rings 33 are carefully designed to adapt to bottles 5 of different specifications. The top and bottom of each ring 33 are threadedly connected with a telescopic column 30. This connection method is not only firm and reliable, but also convenient for quick operation when the position and spacing of the arc piece 31 need to be adjusted. The design of the telescopic column 30 enables the arc piece 31 to be adaptively adjusted according to the specifications of the bottle body 5, which improves the versatility and adaptability of the heating device 27.

[0060] The front of the arc piece 31 is provided with an inner groove 34, and the heating wires laid in the inner groove 34 are the key components for realizing electromagnetic heating. These heating wires are specially treated to generate high heat in a short time and have good heat resistance and stability. The front end of the arc piece 31 is semi-conical and the rear end is semi-cylindrical, which can ensure that the end of the bottle body 5 can be smoothly inserted between the arc pieces 31. Specific embodiment four:

[0062] like Figure 1-14 As shown, according to the contents of the specific embodiment one, the following contents are further disclosed: a second frame plate 13 is welded on both sides of the top of the workbench 1, a second cylinder controller 35 is installed on the back of the second frame plate 13, the end of the second cylinder controller 35 is electrically connected to the second cylinder assembly 36, the end of the second cylinder assembly 36 is clamped with a mounting plate 37, the front of the mounting plate 37 is clamped with a rotating unit 38, the front of the rotating unit 38 is transmission-connected to the extrusion end 39, and it should be noted that a position sensor is also installed in the middle of the front of the extrusion end 39.

[0063] Extrusion ports 40 are provided on both sides of the front side of the extrusion end 39 as well as on the top and the bottom. A clamp group 41 is provided inside the extrusion port 40. The shape of the clamp group 41 is snowflake-shaped. A mold 42 is clamped in the middle of the clamp group 41. The snowflake-shaped clamp group 41 here is composed of five groups of clips. An inner mold 43 is provided on the front side of the mold 42. Processing ends 44 are provided at both ends of the bottle body 5. The mold 42 is clamped and restricted.

[0064] The second frame plate 13 provides a solid support structure for subsequent extrusion and rotation operations. They not only bear the weight from the second cylinder assembly 36 and the rotating unit 38, but also remain stable throughout the operation to ensure the accuracy of extrusion and rotation.

[0065] The second cylinder controller 35 is installed on the back of the second frame 13. This controller plays a key role. It can accurately control the action of the second cylinder assembly 36, and determine the extension length and speed of the second cylinder assembly 36 according to the preset program and the information fed back by the position sensor. The end of the second cylinder assembly 36 is clamped with a mounting plate 37. This clamping method is convenient for installation and disassembly, and can ensure the firmness of the connection. The mounting plate 37, as an intermediate component connecting the second cylinder assembly 36 and the rotating unit 38, needs to have sufficient strength and rigidity to withstand various forces generated during the extrusion and rotation process.

[0066] The front of the mounting plate 37 is connected with a rotating unit 38, which is the core component for polishing the bottle end. It consists of a motor, a reducer and a transmission mechanism, and can provide sufficient torque and speed to drive the extrusion end 39 and the mold 42 to rotate. The motor of the rotating unit 38 adopts a high-performance AC motor or DC motor, and the reducer can select different reduction ratios as needed to meet different speed and torque requirements. The transmission mechanism can use gear transmission, belt transmission or chain transmission to transmit the power of the motor to the extrusion end 39. The front of the rotating unit 38 is connected to the extrusion end 39.

[0067] Extrusion ports 40 are provided on both sides of the front side of the extrusion end 39 and on the top and bottom. The positions and sizes of these extrusion ports 40 are carefully designed to adapt to bottles 5 and molds 42 of different specifications. A clamp group 41 is provided inside the extrusion port 40. The shape of the clamp group 41 is snowflake-shaped. This design is not only beautiful but also has good clamping force and stability. The clamp group 41 is composed of five groups of clips. Each group of clips can independently adjust the position and angle to adapt to molds 42 of different shapes and sizes. The clips of the clamp group 41 are made of high-strength steel or alloy materials. After precision machining and heat treatment, they have good wear resistance and corrosion resistance. A small hydraulic cylinder is installed on the top bucket of each group of clips. By controlling the pressure and flow of the hydraulic system, the piston of the hydraulic cylinder can push the clip to move to adjust the clamping distance. This adjustment can be controlled manually, so the specific structure and method will not be described in detail.

[0068] The middle part of the clamp group 41 holds a mold 42, which is a key component for achieving extrusion and grinding of the bottle end. The inner front of the mold 42 is provided with an inner mold 43, and the shape and size of the inner mold 43 match the processing requirements of the bottle end. The mold 42 is made of high-strength alloy steel or cemented carbide material, and has good hardness, wear resistance and corrosion resistance after precision processing and heat treatment. At the same time, the mold 42 is very convenient to replace, and the processed end of the bottle 5 is the same as the processed end 44.

[0069] When the extrusion and grinding are completed, the second cylinder controller 35 controls the second cylinder assembly 36 to retract, and moves the extrusion end 39 away from the end of the bottle body.
