Description

Technical Field

[0001] The present invention belongs to the technical field of metal filter cartridge forming, and specifically relates to a forming device for a metal filter cartridge. Background Art

[0002] A metal filter cartridge is a porous filtering element made of metal materials, which is widely used in fields such as chemical industry, petroleum, food, pharmaceuticals, and environmental protection for solid-liquid / gas separation, dust collection, or filtration of high-temperature corrosive media. Its structural composition usually includes a cylinder body and a bottom cover. The cylinder body is formed by rolling and welding a metal strip with mesh holes, and the bottom cover is connected to the cylinder body through circumferential welding to seal one end to form a complete metal filter cartridge. For the forming of the metal filter cartridge, it is mainly divided into the rolling and welding forming of the filter cartridge cylinder body and the connection forming of the filter cartridge cylinder body and the bottom cover.

[0003] In the existing metal filter cartridge forming device, when forming and welding the filter cartridge cylinder body and the bottom cover, the filter cartridge cylinder body is usually sleeved on a suitable sleeve, and after being fixed, it is aligned and welded with the top cover. However, limited by the slight dimensional deviation of different individual filter cartridge cylinder bodies of the same model, when sleeved and fixed on the suitable sleeve and subsequent forming welding is completed, there are fixing problems caused by inappropriate filter cartridge cylinder body dimensions. When the filter cartridge cylinder body is smaller in size, it is difficult to insert it into the suitable sleeve, and it is difficult to separate after insertion. When the filter cartridge cylinder body is larger in size, the inserted filter cartridge cylinder body cannot maintain stability, and when additional clamping and supporting equipment is added, due to the certain elasticity of the filter cartridge cylinder body itself, it is easy to cause extrusion deformation of the filter cartridge cylinder body during support and clamping, and it is difficult to maintain a complete cylindrical shape, thereby affecting the quality of subsequent welding forming, and the comprehensive use effect is not good.

[0004] In addition, currently when welding the filter cartridge cylinder body and the bottom cover, the filter cartridge cylinder body and the bottom cover need to be operated separately. After the filter cartridge cylinder body is fixed and supported, it is also necessary to operate the bottom cover to align with the filter cartridge cylinder body, and it is necessary to make the filter cartridge cylinder body and the bottom cover rotate synchronously and cooperate with the outer forming welding end to complete welding forming. Currently, two solutions are adopted. One is to use two groups of rotating devices to respectively control the rotation of the filter cartridge cylinder body and the bottom cover, and maintain synchronous rotation under the condition that the filter cartridge cylinder body and the bottom cover are aligned and in contact, to complete circumferential welding between the filter cartridge cylinder body and the bottom cover under relative static conditions. The other is to press-clamp the bottom cover with the filter cartridge cylinder body, and use the static friction force under pressure to make the filter cartridge cylinder body and the bottom cover rotate synchronously and complete welding. However, the former has a large difficulty in adjusting the synchronization rate of the dual-power devices and there are synchronization deviations, and the latter is prone to deformation of the contact edges of the filter cartridge cylinder body and the bottom cover under extrusion, and neither can achieve fast and stable synchronous forming welding.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention utilizes a sleeve assembly, an elastic linkage assembly, a rotating conductive member, a distribution and connection assembly, a connection opening and closing loop, an energy storage and compression assembly, and an air supply assembly. When the filter cartridge body and the bottom cover are formed and welded, the filter cartridge body is sleeved on the outside of the sleeve assembly, and two-way conduction is achieved when the filter cartridge body is moved upward, so that the air supply assembly can introduce pressurized air into the sleeve assembly and the energy storage and compression assembly respectively. On the one hand, the pressurized air introduced into the sleeve assembly is used to realize a small amount of movement of the surrounding distributed tensioning assembly, and the filter cartridge body that is movably sleeved on the outside of the sleeve assembly is subjected to a small amount of tensioning to perform auxiliary support. The support can avoid the problem that the filter cartridge body is too large to be convenient for sleeve fixing, and the slight opening of the tensioning assembly reduces the tensioning deformation of the filter cartridge body, thereby achieving stable support and fixation before forming and welding. On the other hand, in conjunction with the energy storage effect in the energy storage compression assembly, after the forming and welding is completed, the energy storage compression assembly is released and opened, and the sleeved filter cartridge body is pushed downward by the energy storage compression assembly to complete the quick discharge under impact, avoiding the problem that the filter cartridge body is too large to be convenient for discharge after sleeve fixing, and coping with the assembly problems caused by slight differences in the size of the metal filter cartridge itself, and achieving adaptive assembly and fixation processing.

[0020] 2. The present invention uses the above-mentioned fixing treatment of the filter cartridge body, in conjunction with the electromagnet 1 at the bottom of the sleeve assembly, and in conjunction with the rotatable tray in the bottom support assembly, and the magnetic sheet in the top seat. When the filter cartridge body and the bottom cover of the metal filter cartridge are formed and welded, the bottom cover is supported from the bottom by the bottom support assembly and aligned with the bottom of the filter cartridge body above, and the electromagnet 1 is energized to magnetically attract the magnetic sheet downward, so that the tray is magnetically clamped to the bottom of the sleeve assembly, and the bottom cover and the filter cartridge body are magnetically clamped and fixed, and the filter cartridge body and the bottom cover can rotate with the sleeve assembly to complete the welding of the outer contact circumferential line during the rotation process, thereby overcoming the problem of inconvenient welding operation caused by the bottom cover and the bottom of the filter cartridge body. The magnetic attraction effect is used to enable the aligned and assembled metal filter cartridges to rotate stably and synchronously, completing the circumferential welding forming under stable synchronous rotation.

[0021] 3. The present invention reuses the base support assembly, sleeve assembly and tensioning assembly, and cooperates with the detection part that moves with the base support assembly. During the forming and welding process, the detection part is moved to the outside of the filter cartridge body. On the one hand, in cooperation with the tensioning pressure of the tensioning assembly, the defect detection is performed on the outside of the rotating filter cartridge body under the tensioning pressure, and the detection of the rolled weld of the filter cartridge body is completed. The forming process of the filter cartridge body that does not meet the quality standards is interrupted in time. On the other hand, while the sleeve assembly drives the welding of the filter cartridge body and the bottom cover, the newly welded welds at the circumference are synchronously inspected, thereby comprehensively improving the yield rate of the metal filter cartridge forming and greatly improving the quality inspection effect.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a forming device for a metal filter cartridge, including a base 1, a driving component 4, and a forming and welding end 6. Above the base 1, a bottom support component 3 is provided. Above the bottom support component 3, a sleeve component 7 is provided. A tensioning component 8 is distributed around the outside of the sleeve component 7. The output end of the driving component 4 is fixedly connected to a rotating conduction member 9. The bottom of the rotating conduction member 9 is fixedly connected to an elastic linkage component 10. An air supply component 12 and a distribution and connection component 13 are respectively sleeved on the outside of the rotating conduction member 9. The sleeve component 7 is sleeved on the outside of the elastic linkage component 10 and is elastically connected to the elastic linkage component 10. A energy storage and compression component 14 is fixedly provided on the outside of the distribution and connection component 13. The elastic linkage component 10 includes a fixed rod 101, a second spring 102, a side plate 103, a second side port 104, and a conduction cavity 105. One end of the second spring 102 is fixedly connected to the bottom of the fixed rod 101, and the other end of the second spring 102 is fixed inside the sleeve component 7. The side plate 103 is fixedly connected to the outside of the fixed rod 101 and is slidably sleeved in the sleeve component 7. The second side port 104 is opened on the side plate 103 and is communicated with the conduction cavity 105. The sleeve component 7 slides upward along the elastic linkage component 10 and is communicated with the rotating conduction member 9, so that the air supply component 12 controls the expansion of the tensioning component 8. The sleeve component 7 slides upward and simultaneously controls the conduction of the distribution and connection component 13 and the energy storage and compression component 14, so that the air supply component 12 controls the energy storage of the energy storage and compression component 14.

[0037] Embodiment 1: During use, take out the filter cartridge cylinder to be formed and welded, and sleeve it outside the sleeve assembly 7, so that the top of the filter cartridge cylinder abuts against the limit plate 73. Randomly push up the sleeved filter cartridge cylinder, and drive the sleeve assembly 7 to move up synchronously. While compressing the second spring 102, the cylinder body 71 moves upward along the outside of the fixed rod 101, and at the same time, push the push block 145 in the energy storage compression assembly 14, so that the push rod 143 in the energy storage compression assembly 14 moves upward and compresses the fourth spring 144 to complete the pre-stage energy storage compression. After the movement, the communication port 76 in the sleeve assembly 7 is aligned and communicated with the side port two 104. At the same time, as the cylinder body 71 moves upward, it also drives the top communication opening and closing ring 15 to move upward, so that the communication opening and closing ring 15 is sleeved into the second annular cavity 132 of the distribution and communication assembly 13, and pushes up the magnetic ring 134. While compressing the third spring 135, the middle hole 152 on the outside of the fixed ring 151 is communicated with the through hole 133. At this time, start the air supply assembly 12. The air pump 122 enters the communication sleeve 121 through the communication frame 123 and the communication pipe 124, and is input into the distribution cavity 93 through the first through hole 94. On the one hand, the pressurized air entering the distribution cavity 93 passes through the conduction cavity 105, the side port two 104, the communication port 76, and the annular cavity 75 and enters the side groove 74, pushing the tensioning assembly 8 to move, stretching the first spring 83 and fixing it tightly from the inside of the filter cartridge cylinder. On the other hand, a part of the pressurized air entering the distribution cavity 93 is input into the fixed pipe 141 along the second through hole 95, the through hole 133, the middle hole 152, and the side pipe 137. The pressurized air input into the fixed pipe 141 replaces the compression of the push block 145 by the filter cartridge cylinder, and uses the internal pressurized air to compress the fourth spring 144 to complete the pneumatic energy storage. Then, release the elastic reset of the second spring 102 in the upper elastic linkage assembly 10 of the sleeve assembly 7, and push the sleeve assembly 7 to move downward and reset. While sealing the communication port 76, the communication opening and closing ring 15 moves out of the distribution and communication assembly 13. As the magnetic ring 134 resets, the distribution and communication assembly 13 is resealed. The energy storage compression assembly 14 maintains the energy storage state. Place the bottom cover to be assembled and welded on the bottom support assembly 3, move the bottom support assembly 3 so that the bottom cover moves to the bottom of the sleeve assembly 7, and make the bottom cover align and contact with the bottom of the filter cartridge cylinder. Start the driving assembly 4 to drive the rotating conduction member 9 and the elastic linkage assembly 10 to rotate, and drive the sleeve assembly 7 to rotate. At the same time, start the first electromagnet 11. The first electromagnet 11 is energized to generate a magnetic attraction force and adsorb the upper end of the bottom support assembly 3 downward, so that the sleeve assembly 7 drives the outer filter cartridge cylinder and the bottom cover in alignment contact to rotate together. Start the forming and welding end 6 to weld at the contact circumference of the rotating filter cartridge cylinder and the bottom cover to complete the forming and welding. After the welding is completed, move the bottom support assembly 3 away. At the same time, start the second electromagnet 136 in the distribution and communication assembly 13, which is energized to generate a magnetic force and magnetize the magnetic ring 134 downward, so that the through hole 133 opens the bypass. The compressed air in the energy storage compression assembly 14 is automatically emptied, and the fourth spring 144 is elastically reset.The push rod 143 drives the push block 145 to quickly move downward and reset, and the formed filter cartridge sleeved on the outside of the sleeve assembly 7 is impacted and pushed out, completing the automatic discharge.

[0038] First, by using the sleeve assembly 7, the elastic linkage assembly 10, the rotating conductive member 9, the distribution and connection assembly 13, the connecting opening and closing loop 15, the energy storage compression assembly 14 and the air supply assembly 12, when the filter cartridge body and the bottom cover are formed and welded, the filter cartridge body is sleeved on the outside of the sleeve assembly 7, and two-way conduction is achieved when the upward push is made, so that the air supply assembly 12 can introduce pressurized air into the sleeve assembly 7 and the energy storage compression assembly 14 respectively. On the one hand, the pressurized air introduced into the sleeve assembly 7 is used to realize a small amount of movement of the surrounding tensioning assembly 8, so as to perform a small amount of tension on the filter cartridge body that is movably sleeved on the outside of the sleeve assembly 7. The auxiliary support under the tightness avoids the problem of the filter cartridge body being too large and inconvenient to be socketed and fixed, and the slight opening of the tensioning assembly 8 reduces the tensioning deformation of the filter cartridge body, thereby achieving stable support and fixation before forming and welding. On the other hand, in conjunction with the energy storage effect in the energy storage compression assembly 14, after the forming and welding is completed, the energy storage compression assembly 14 is released and opened, and the socketed filter cartridge body is pushed downward by the energy storage compression assembly 14 to complete the quick discharge under impact, avoiding the problem of the filter cartridge body being too large and inconvenient to discharge after socketing, and coping with the assembly problems caused by slight differences in the size of the metal filter cartridge itself, and achieving adaptive assembly and fixation processing.

[0039] In addition, through the above-mentioned fixing treatment of the filter cartridge body, in conjunction with the electromagnet 11 at the bottom of the sleeve assembly 7, and in conjunction with the rotatable tray 33 in the bottom support assembly 3, and the magnetic sheet 34 in the top seat 32, when the filter cartridge body and the bottom cover of the metal filter cartridge are formed and welded, the bottom cover is supported from the bottom by the bottom support assembly 3 and aligned with the bottom of the filter cartridge body above, and the electromagnet 11 is energized to magnetically attract the magnetic sheet 34 downward, so that the tray 33 is magnetically clamped at the bottom of the sleeve assembly 7, and the bottom cover and the filter cartridge body are magnetically clamped and fixed, and the filter cartridge body and the bottom cover can rotate with the sleeve assembly 7 to complete the welding of the outer contact circular circumference line during the rotation process, thereby overcoming the problem of inconvenient welding operation caused by the bottom cover and the bottom of the filter cartridge body, and utilizing the magnetic attraction effect to enable the aligned and assembled metal filter cartridges to stably rotate synchronously, completing the circumferential welding forming under stable synchronous rotation.

[0040] Embodiment 2: When the sleeving of the filter cartridge cylinder is completed and the tensioning auxiliary fixation of the tensioning assembly 8 is completed, multiple groups of circumferentially distributed tensioning assemblies 8 disperse the tensioning force inside the filter cartridge cylinder. When the movable bottom support assembly 3 is moved to align the bottom cover, the detection part 16 is synchronously driven to move and contact the filter cartridge cylinder outside the sleeve assembly 7. The driving assembly 4 is used to rotate the sleeve assembly 7, and drive the externally tensioned and sleeved filter cartridge cylinder to rotate. The defect detection mechanism in the detection part 16 is started to detect the defects on the outside of the fully tensioned filter cartridge cylinder, and identify whether there are defects such as cracks at the welded joints of the filter cartridge cylinder under the fully tensioned pressure. And after the circumferential welding of the filter cartridge cylinder and the bottom cover is completed during the rotation process, the detection of the newly welded weld seam is completed at the same time, and the synchronous quality inspection is completed.

[0041] First of all, by using the bottom support assembly 3, the sleeve assembly 7 and the tensioning assembly 8 again, and cooperating with the detection part 16 that moves with the bottom support assembly 3, during the forming and welding process, the detection part 16 is moved to the outside of the filter cartridge cylinder. On the one hand, in cooperation with the tensioning pressure of the tensioning assembly 8, the outside of the rotating filter cartridge cylinder under the tensioning pressure is detected for defects, and the detection of the rolled and welded part of the filter cartridge cylinder is completed. The forming process of the filter cartridge cylinder with unqualified quality is interrupted in time. On the other hand, while the sleeve assembly 7 drives the filter cartridge cylinder and the bottom cover to be welded, the synchronous quality inspection of the newly welded weld seam at the circumference is realized, comprehensively improving the yield rate of the metal filter cartridge forming and greatly improving the quality inspection effect.

[0042] Among them, an electromagnet 11 is fixedly nested at the bottom of the sleeve assembly 7. The bottom support assembly 3 includes an electric push rod 31, a top seat 32, a tray 33, a magnetic sheet 34 and a rotating rod 35. The rotating rod 35 is rotatably installed on the top of the top seat 32 through a bearing. The movable end of the electric push rod 31 is fixedly connected to the top seat 32. The tray 33 is fixedly connected to the top of the rotating rod 35. The magnetic sheet 34 is fixedly nested in the tray 33. The electromagnet 11 is energized to generate a magnetic force and magnetically adsorbs with the magnetic sheet 34. A moving assembly 2 is provided on the top of the base 1. The moving assembly 2 controls the lateral movement of the bottom support assembly 3. The moving assembly 2 includes an electric push rod 21 and a carrier plate 22. The electric push rod 21 is fixed to the base 1 through a connecting block. The carrier plate 22 is fixedly connected to the movable end of the electric push rod 21. The top of the carrier plate 22 is fixedly connected to the electric push rod 31.

[0043] By utilizing the magnetic attraction generated when the electromagnet 11 is energized and cooperating with the magnetic sheet 34 for magnetic attraction, the bottom cover placed above the magnetic sheet 34 is magnetically attracted and clamped at the bottom of the sleeve assembly 7. The bottom support assembly 3 cooperates with the electric push rod 31 and the moving assembly 2 to achieve left - right and up - down movement, realizing the movement control of the supported bottom cover. On the one hand, it ensures that the bottom cover is fully aligned and in contact with the bottom of the filter cartridge cylinder after movement. On the other hand, it moves away after forming and welding, reserving space for the metal filter cartridge to be pushed out by the energy - storage compression assembly 14 after welding. The tray 33 can freely rotate on the top of the top seat 32 through the rotating rod 35, facilitating the tray 33 after magnetic attraction to rotate synchronously with the sleeve assembly 7.

[0044] Among them, the sleeve assembly 7 includes a cylinder body 71, an internal cavity 72, a limiting plate 73, a side groove 74, an annular cavity 75, and a communication port 76. The side groove 74 is opened on the outer side of the cylinder body 71. The internal cavity 72 is opened at the top of the cylinder body 71 and extends into the interior of the cylinder body 71. The limiting plate 73 is fixedly arranged around the upper part of the outer surface of the cylinder body 71, and there are gaps between adjacent limiting plates 73. Both the annular cavity 75 and the communication port 76 are opened in the cylinder body 71. The two ends of the communication port 76 are respectively communicated with the internal cavity 72 and the annular cavity 75.

The push plate 81 is fixedly connected to the opening plate 82. Both the push plate 81 and the opening plate 82 are movably sleeved in the side groove 74.

The inner end of the second spring 102 is fixedly connected in the internal cavity 72.

[0045] The sleeve assembly 7 realizes the sleeving of the filter cartridge cylinder body, and the internal cavity 72, the side groove 74, the annular cavity 75, and the communication port 76 provide a ventilation channel, ensuring that the pressure air input inside can push the tensioning assembly 8 to move outward slightly, completing the circumferential tensioning at the inner wall of the filter cartridge cylinder body. And the slight movement adapts to the situation where the size of the filter cartridge cylinder body is slightly larger. At the same time, it reduces the deformation of the filter cartridge cylinder body when tensioning with a large displacement. The limiting plate 73 positions and sleeves the filter cartridge cylinder body to ensure the alignment of the bottom position of the filter cartridge cylinder body.

[0046] Among them, the rotating and conducting part 9 includes a connecting shaft 91, a communicating head 92, a distribution cavity 93, a first through - hole 94, and a second through - hole 95. The communicating head 92 is fixedly connected to the connecting shaft 91. The distribution cavity 93 is opened at the bottom of the communicating head 92. The bottom of the communicating head 92 is fixedly connected to the upper end of the fixed rod 101. The distribution cavity 93 is communicated with the conducting cavity 105. Both the first through - hole 94 and the second through - hole 95 are opened on the outer side surface of the communicating head 92 and are both communicated with the distribution cavity 93.

[0047] The rotating conducting part 9 realizes bidirectional conduction. By using the compressed air input by the air supply component 12 and in cooperation with the first through hole 94 and the second through hole 95, under the condition that the sleeve component 7, the energy storage compression component 14 and the rotating conducting part 9 are in conduction connection, bidirectional conduction is completed, and at the same time, the tension control of the tensioning component 8 and the energy storage control of the energy storage compression component 14 are completed.

[0048] Among them, the distribution and connection component 13 includes a distribution sleeve 131, a second annular cavity 132, a guide through hole 133, a magnetic ring 134, a third spring 135, a second electromagnet 136 and a side pipe 137. The distribution sleeve 131 is fixedly sleeved on the outer side of the connection head 92. The second annular cavity 132 is opened at the bottom of the distribution sleeve 131. The guide through hole 133 is opened on the inner wall of the distribution sleeve 131 and penetrates through the outer wall of the distribution sleeve 131. The magnetic ring 134 is movably sleeved in the second annular cavity 132. One end of the third spring 135 is fixed to the top of the magnetic ring 134 and the other end is fixedly connected in the second annular cavity 132. The second electromagnet 136 is fixedly nested on the top of the distribution sleeve 131 and generates magnetic force when energized and magnetically attracts the magnetic ring 134. A first side through hole is provided at the top of the distribution sleeve 131 and is communicated with the second annular cavity 132. The side pipe 137 is fixedly connected to the outer side surface of the distribution sleeve 131 and is communicated with the guide through hole 133. A connection opening and closing ring 15 is fixedly connected to the top of the sleeve component 7. The connection opening and closing ring 15 includes a fixed ring 151 and a middle hole 152. The fixed ring 151 is adapted to the second annular cavity 132. The middle hole 152 is opened on the outer side surface of the fixed ring 151. The guide through hole 133 is located on the moving path of the middle hole 152.

[0049] The distribution and connection component 13 is mainly used to control the conduction between the energy storage compression component 14 and the rotating conducting part 9, and to realize the pressure relief control of the energy storage compression component 14. In cooperation with the connection opening and closing ring 15, when the connection opening and closing ring 15 moves upward following the sleeve component 7, it is inserted into the distribution and connection component 13, so that the rotating conducting part 9 is communicated with the energy storage compression component 14 through the middle hole 152 of the connection opening and closing ring 15. And when the sleeve component 7 drives the connection opening and closing ring 15 to move out, the magnetic ring 134 elastically resets to seal the guide through hole 133 in the distribution and connection component 13, so that the compressed air inside the energy storage compression component 14 is maintained in a sealed state, and the fourth spring 144 is compressed to realize energy storage. The third spring 135 is used to elastically reset the magnetic ring 134. When the second electromagnet 136 magnetizes the magnetic ring 134, it actively opens the guide through hole 133 to release the compressed air in the energy storage compression component 14, cooperates with the fourth spring 144 to realize reset, and completes impact and material pushing. The first side through hole bypasses the upper space air of the second annular cavity 132 to ensure the pressure balance at the top of the magnetic ring 134 during the dynamic sealing sliding, and avoid the difficulty of movement caused by the airtightness of the air above the magnetic ring 134.

[0050] Among them, the energy storage compression assembly 14 includes a fixed pipe 141, a connecting ring frame 142, a push rod 143, a fourth spring 144 and a push block 145. The fixed pipe 141 is fixedly connected to and communicates with the side pipe 137. The connecting ring frame 142 is fixed on the end face of the fixed pipe 141. One end of the push rod 143 is movably sleeved in the fixed pipe 141, and the other end is fixedly connected to the push block 145. The inner end of the push rod 143 is the large end. An annular chamber is formed between the middle part of the push rod 143 and the fixed pipe 141, and this annular chamber communicates with the side pipe 137. There is a second bypass hole on the outer side of the connecting ring frame 142 and it communicates with the inside of the fixed pipe 141. The push block 145 corresponds to the notch in the sleeve assembly 7 one by one.

[0051] In the initial stage of the energy storage compression assembly 14, the filter cartridge cylinder on the sleeve assembly 7 actively pushes the push block 145 to complete preliminary energy storage, and maintains the compressed state after subsequent pressure air is injected. The second bypass hole ensures the stability of the air pressure above the large end of the push rod 143, avoids the sealing above the large end of the push rod 143 from restricting its own movement, and realizes top bypass pressure relief. The middle diameter of the push rod 143 is smaller than its large end diameter, and an annular chamber is formed inside the fixed pipe 141 in the middle section of the push rod 143. By introducing pressure air into this annular chamber, the pushing of the push rod 143 is realized.

[0052] Among them, the driving assembly 4 includes a power motor 41 and a bracket 42. There is a motor frame outside the power motor 41, and the power motor 41 is fixed in the motor frame. The bracket 42 is fixed at the bottom of the motor frame. One end of the rotating conduction part 9 is rotatably sleeved with the bracket. The top of the base 1 is fixedly connected with a support connecting rod 5, and the upper end of the support connecting rod 5 is fixedly connected with the motor frame. The forming welding end is fixed on the outside of the driving assembly 4 through a support plate. The welding end of the forming welding end is located at the bottom outside the sleeve assembly 7. The air supply assembly 12 includes a connecting sleeve 121, an air pump 122, a connecting frame 123 and a connecting pipe 124. The connecting sleeve 121 is sleeved outside the connecting head 92 and communicates with the first through hole 94. One end of the connecting pipe 124 is fixedly connected and communicated with the connecting sleeve 121, and the other end is fixedly connected and communicated with the connecting frame 123. The air outlet end of the air pump 122 is fixedly connected and communicated with the connecting frame 123. The air pump 122 inputs pressure air into the rotating conduction part 9.

[0053] The driving assembly 4 provides rotational force to maintain stable rotation and complete subsequent rotational welding and other operations. The air supply assembly 12 provides pressure air. There is a sealing ring (not shown in the figure) between the connecting sleeve 121 and the connecting head 92 to ensure that gas leakage is avoided when the connecting head 92 rotates in the connecting sleeve 121. The welding end part of the forming welding end 6 is telescopically adjustable to adapt to and approach the outside of the sleeve assembly 7 to complete the welding process.

[0054] Among them, a detection part 16 is fixedly connected to the outer side of the bottom support assembly 3. The detection part 16 includes a vertical plate and metal flaw detection structures arrayed and fixed on the vertical plate. The forming and welding end 6 and the detection part 16 are distributed on the left and right sides of the sleeve assembly 7.

[0055] The metal flaw detection structure is specifically a pulsed eddy current detector or an electromagnetic ultrasonic detector, both of which are existing components, and the models are Lyft PEC and EMAT-2000 respectively.

[0056] Working principle and usage process of the present invention: During use, take out the filter cartridge cylinder to be formed and welded, and sleeve it on the outside of the sleeve assembly 7, so that the top of the filter cartridge cylinder abuts against the limit plate 73. Then, randomly push up the sleeved filter cartridge cylinder, driving the sleeve assembly 7 to move upward synchronously. While compressing the second spring 102, the cylinder body 71 moves upward along the outside of the fixed rod 101, and simultaneously pushes the push block 145 in the energy storage compression assembly 14, causing the push rod 143 in the energy storage compression assembly 14 to move upward and compress the fourth spring 144, completing the pre-stage energy storage compression. After that, the communication port 76 in the sleeve assembly 7 aligns and communicates with the side port two 104 after moving. At the same time, as the cylinder body 71 moves upward, it also drives the top communication start and close loop 15 to move upward, so that the communication start and close loop 15 is sleeved into the second annular cavity 132 of the distribution and communication assembly 13, and pushes the magnetic ring 134 upward. While compressing the third spring 135, the middle hole 152 on the outside of the fixed ring 151 communicates with the guide through hole 133. At this time, start the air supply assembly 12. The air pump 122 enters the communication sleeve 121 through the communication frame 123 and the communication pipe 124, and is input into the distribution cavity 93 through the first through hole 94. On the one hand, the pressurized air entering the distribution cavity 93 passes through the conduction cavity 105, the side port two 104, the communication port 76, and the annular cavity 75 and enters the side groove 74, pushing the tensioning assembly 8 to move, stretching the first spring 83 while being tensioned and fixed from the inside of the filter cartridge cylinder. On the other hand, part of the pressurized air entering the distribution cavity 93 is input into the fixed pipe 141 through the second through hole 95, the guide through hole 133, the middle hole 152, and the side pipe 137. The pressurized air input into the fixed pipe 141 replaces the compression of the push block 145 by the filter cartridge cylinder, and uses the internal pressurized air to compress the fourth spring 144 to complete pneumatic energy storage. Subsequently, release the elastic reset of the second spring 102 in the upper elastic linkage assembly 10 of the sleeve assembly 7, and push the sleeve assembly 7 to move downward and reset. While sealing the communication port 76, the communication start and close loop 15 moves out of the distribution and communication assembly 13. As the magnetic ring 134 resets, the distribution and communication assembly 13 is resealed again. The energy storage compression assembly 14 maintains the energy storage state. Place the bottom cover to be assembled and welded on the bottom support assembly 3, move the bottom support assembly 3 so that the bottom cover moves to the bottom of the sleeve assembly 7, and make the bottom cover align and contact with the bottom of the filter cartridge cylinder. Start the drive assembly 4, drive the rotation and conduction member 9 and the elastic linkage assembly 10 to rotate, and drive the sleeve assembly 7 to rotate. At the same time, start the first electromagnet 11. The first electromagnet 11 is energized to generate magnetic attraction and adsorb the upper end of the bottom support assembly 3 downward, so that the sleeve assembly 7 drives the filter cartridge cylinder on the outside and the bottom cover in alignment and contact to rotate together. Start the forming and welding end 6, and weld at the contact circumference of the rotating filter cartridge cylinder and the bottom cover to complete the forming and welding. After the welding is completed, move the bottom support assembly 3 away. At the same time, start the second electromagnet 136 in the distribution and communication assembly 13. The second electromagnet 136 is energized to generate magnetic force and magnetize the magnetic ring 134 downward, so that the guide through hole 133 opens the bypass, and the compressed air in the energy storage compression assembly 14 is automatically emptied, and the fourth spring 144 is elastically reset.And the push rod 143 drives the push block 145 to quickly move down and reset, so as to impact and push out the formed filter cartridge sleeved outside the sleeve assembly 7, completing automatic discharging;

[0057] When the sleeving of the filter cartridge body is completed and the tensioning and auxiliary fixing of the tensioning assembly 8 are completed, multiple groups of circumferentially distributed tensioning assemblies 8 disperse the tensioning force inside the filter cartridge body. When the movable bottom support assembly 3 moves to align the bottom cover, it synchronously drives the detection part 16 to move and contact the filter cartridge body outside the sleeve assembly 7. The driving assembly 4 is used to rotate the sleeve assembly 7 and drive the filter cartridge body sleeved and tensioned outside to rotate. The defect detection mechanism in the detection part 16 is started to detect the defects on the outside of the fully tensioned filter cartridge body, and identify whether there are defects such as cracks at the welded joints of the filter cartridge body under the fully tensioned pressure. And after the circumferential welding of the filter cartridge body and the bottom cover is completed during the rotation process, the detection of the newly welded weld seam is completed at the same time, completing synchronous quality inspection.
