[0017] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a connection structure of a barrel body air supply device includes a conical top 1 and a fixed flange 2. The fixed flange 2 is located at the lower end of the conical top 1. An air supply hole 4 is provided at the top end of the conical top 1, and an air supply flanging socket 5 is provided at the upper end position of the air supply hole 4. The air supply hole 4 is formed by hydraulic stretching. Position the prepared metal sheet on the workbench of the hydraulic stretching machine and fix it through the clamping device to ensure that the material does not move during the forming process. Start the hydraulic stretching equipment, and by controlling the hydraulic pressure and speed, stretch the metal sheet into the air supply hole with a conical top structure at the specified position. According to the steel plate thickness and forming requirements, set the initial stretching pressure and speed. The pressure is generally in the range of 50 to 200 MPa, and the stretching speed is controlled within 0.1 to 10 mm / s. During the stretching process, monitor the pressure, speed, and deformation amount in real time to ensure that the hole diameter is uniform, the shape is regular, and avoid cracking or deformation caused by excessive stretching of the material. An air supply flanging socket 5 is provided at the upper end position of the air supply hole 4, a positioning member 6 is provided at the inner lower end position of the conical top 1, and a sealing ring 7 is provided at the outer lower end position of the fixed flange 2. The lower end of the air supply flanging socket 5 communicates with the conical top 1. First, carry the connection structure of the barrel body air supply device to the use position, place the connection structure of the barrel body air supply device into the barrel body, the fixed flange 2 is clamped to the inner side of the barrel body, and the positioning member 6 pushes the pressing plate 11 into the barrel body to complete the positioning. Weld the connection between the fixed flange 2 and the barrel body. Then, insert the air supply pipe into the air supply hole 4 and turn it to be fixed inside the air supply flanging socket 5. Finally, start using, and supply air through the air supply flanging socket 5 to the air supply pipe for the air supply operation. The air supply flanging socket 5 is processed by punching and flanging. Use a specially designed punching die to determine the punching diameter according to the specifications of the air supply valve. The punching die needs to have high precision and wear resistance to ensure the punching quality. Perform the punching operation at the center position of the air supply hole in the conical top. During the punching process, maintain the centering between the die and the material to ensure that the hole diameter is accurate and the hole wall is smooth without burrs. The punching diameter should be accurately calculated and controlled according to the installation requirements of the air supply valve. The design of the flanging die needs to consider the height and angle of the flanging to ensure that the formed socket structure after flanging can closely cooperate with the air supply valve. The material of the flanging die needs to have high strength and wear resistance. Place the punched metal sheet into the flanging die, and turn the metal around the hole outward by hydraulic or mechanical pressure to form a socket structure. The flanging height and angle are precisely controlled by the die to ensure the strength and sealing performance of the socket. The flanging height is generally between 5 and 10 mm, and the flanging angle is between 30 and 45 degrees.
[0018] In Figure 2 , 3In the middle: The positioning member 6 includes a support plate 8. At the upper end position on the outer side of the support plate 8, a fixing plate 9 is provided. At both ends of the support plate 8, sliding rods 10 are provided. On the outer side of the sliding rods 10, pressing plates 11 are provided. On the outer side of the sliding rods 10, springs 12 are provided. The outer end of the fixing plate 9 is fixed at the inner side position of the conical top 1. The support plate 8 is fixed at the inner side position of the conical top 1 through the fixing plate 9. The inner ends of the sliding rods 10 slide inside the support plate 8. The pressing plates 11 slide on the outer side of the support plate 8 through the sliding rods 10. The springs 12 are located at the corresponding side positions of the support plate 8 and the pressing plates 11. Place the connection structure of the barrel body air supply device into the barrel body. The fixed flange 2 is stuck inside the barrel body. The spring 12 rebounds and the sliding rods 10 slide inside the support plate 8, pushing the pressing plates 11 into the barrel body to complete the positioning.
[0019] The air supply flanging socket 5 adopts the punching and flanging socket process and uses high-strength metal materials (such as stainless steel or aluminum alloy) to ensure that the materials have good ductility, corrosion resistance and strength to meet the requirements of forming and use. Clean the surface of the metal materials to remove oil stains, oxides and other impurities to ensure that the surface is smooth and defect-free, which is beneficial to the subsequent forming process. Position the pretreated metal sheet on the workbench of the hydraulic stretching machine and fix it through the clamping device to ensure that the material will not move during the forming process. Start the hydraulic stretching equipment and stretch the metal sheet into an air supply hole with a conical top structure at the specified position by controlling the hydraulic pressure and speed. Monitor the pressure and deformation in real time during the stretching process to ensure the forming quality and consistency. Use a specially designed punching die to determine the punching diameter according to the specifications of the air supply valve. The punching die needs to have high precision and wear resistance to ensure the punching quality. Perform the punching operation at the center position of the conical top air supply hole. Keep the alignment between the die and the material during the punching process to ensure that the hole diameter is accurate and the hole wall is smooth without burrs. The design of the flanging die needs to consider the height and angle of the flanging to ensure that the socket structure formed after flanging can closely cooperate with the air supply valve. The die material needs to have high strength and wear resistance. Place the punched metal sheet into the flanging die and turn the metal around the hole outwards through hydraulic or mechanical pressure to form a socket structure. Control the flanging height and angle according to the design requirements to ensure the strength and sealing performance of the socket. The air supply valve is installed through the socket structure. During the installation process, the connecting part of the air supply valve is inserted into the flanging hole and is closely combined with the flanging structure by rotating or pressing. The air supply valve and the flanging socket can be fixed by snap, thread or pressing to ensure firm connection and avoid loosening and leakage. Visually inspect the appearance of the connection between the flanging socket and the air supply valve to ensure that there are no obvious deformations, cracks or other defects. Conduct a sealing inspection on the installed air supply device through an airtightness test equipment. Pressurize the test gas to the design pressure and detect whether there is gas leakage at the connection. Record the pressure, time and leakage volume during the test process to ensure that the sealing performance meets the design requirements. According to the test results, adjust and optimize the flanging socket structure to ensure consistent high quality and high sealing performance in mass production.
