Description

Technical Field

[0001] The invention belongs to the technical field of metal filter cartridge molding, and in particular relates to a metal filter cartridge molding device. Background Art

[0002] A metal filter cartridge is a porous filter element made of metal material. It is widely used in chemical, petroleum, food, pharmaceutical and environmental protection fields for solid-liquid / gas separation, dust capture or high-temperature corrosive medium filtration. Its structure usually consists of a cylinder body and a bottom cover. The cylinder body is formed by rolling a metal strip with a mesh and then welding it. The bottom cover is connected to the cylinder body by annular seam welding and one end is closed to form a complete metal filter cartridge. The molding of the metal filter cartridge is mainly divided into the rolling welding molding of the filter cartridge cylinder body and the connection molding of the filter cartridge cylinder body and the bottom cover.

[0003] The metal filter cartridge forming device in the prior art usually uses the method of sleeve-mounting the filter cartridge body on the adapter sleeve when performing the forming welding between the filter cartridge body and the bottom cover, and aligning and welding the filter cartridge body with the top cover after fixing. However, due to the slight size deviation of individual filter cartridge bodies of the same model but different filter cartridge bodies, there is a fixing problem caused by the inappropriate size of the filter cartridge body when the filter cartridge body is sleeved and fixed with the adapter sleeve and the subsequent forming welding is completed. When the filter cartridge body is small in size, it is difficult to insert it into the adapter sleeve and it is difficult to separate it after inserting it. When the filter cartridge body is large in size, the filter cartridge body cannot maintain stability after inserting it. When adding a clamping support device, since the filter cartridge body itself has a certain elasticity, it is easy to cause the filter cartridge body to be squeezed and deformed during support and clamping, and it is difficult to maintain a complete columnar shape, which in turn affects the subsequent welding forming quality, and the overall use effect is not good.

[0004] In addition, at present, when welding the filter cartridge body and the bottom cover, it is necessary to operate the filter cartridge body and the bottom cover separately. After completing the fixed support of the filter cartridge body, it is also necessary to operate the bottom cover to align with the filter cartridge body, and it is necessary to make the filter cartridge body and the bottom cover rotate synchronously and cooperate with the outer forming welding end to complete the welding forming. Currently, two schemes are adopted to achieve this. One is to use two sets of rotating equipment to control the rotation of the filter cartridge body and the bottom cover respectively, and maintain the synchronous rotation of the filter cartridge body and the bottom cover under aligned contact, so as to complete the circumferential welding between the filter cartridge body and the bottom cover under relative static state. The other is to clamp the bottom cover by pressure for the filter cartridge body, and use the static friction force under the action of pressure to make the filter cartridge body and the bottom cover rotate synchronously, and complete the welding. However, the synchronization rate of the former dual power equipment is difficult to adjust, and there is a synchronization deviation. The latter is easy to cause deformation of the contact edge of the filter cartridge body and the bottom cover under extrusion. Both cannot achieve fast and stable synchronous forming welding.

[0015] The beneficial effects of the present invention are as follows: 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.

[0016] 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.

[0017] 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.

[0022] Embodiment 1: During use, the filter cartridge body to be formed and welded is taken out, and sleeved on the outer side of the sleeve assembly 7, so that the top of the filter cartridge body contacts the limit plate 73, and the sleeved filter cartridge body is randomly pushed upward, and the sleeve assembly 7 is driven to move upward synchronously. While compressing the spring 2 102, the cylinder 71 moves along the outer side of the fixing rod 101, and simultaneously pushes 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 spring 4 144, completing the front-stage energy storage compression, and the connecting port 76 in the sleeve assembly 7 is aligned and connected with the side port 2 104 after movement, and at the same time, as the cylinder 71 moves upward, it also drives the top connecting opening and closing ring 15 to move upward, so that the connecting opening and closing ring 15 is sleeved to the distribution connecting group The magnetic ring 134 is pushed upwards into the annular cavity 132 of the component 13, and the middle hole 152 on the outside of the fixing ring 151 is connected with the conducting hole 133 while the spring 135 is compressed. At this time, the air supply component 12 is started, and the air pump 122 enters the connecting sleeve 121 through the connecting frame 123 and the connecting pipe 124, and is input into the distribution cavity 93 through the through hole 1 94. The pressurized air entering the distribution cavity 93 is passed into the side groove 74 along the conducting cavity 105, the side opening 104, the connecting opening 76, and the annular cavity 75, pushing the tensioning component 8 to move, stretching the spring 1 83 while tightening and fixing it from the inside of the filter cartridge body. On the other hand, part of the pressurized air passed into the distribution cavity 93 is passed along the through hole 2 95, the conducting hole 133, the middle hole 152 and the side pipe 137 are input into the fixed pipe 141, and the pressurized air input into the fixed pipe 141 replaces the compression of the filter cartridge body on the push block 145, and the internal pressure air is used to compress the spring four 144 to complete the pneumatic energy storage, and then the spring two 102 in the upper elastic linkage assembly 10 of the sleeve assembly 7 is released to elastically reset, and the sleeve assembly 7 is pushed to move down and reset, and the connecting port 76 is sealed. At the same time, the connecting opening and closing ring 15 is removed from the distribution connecting assembly 13, and as the magnetic ring 134 is reset, the distribution connecting assembly 13 is resealed, and the energy storage compression assembly 14 maintains the energy storage state, and the bottom cover to be assembled and welded is placed on the bottom support assembly 3, and the bottom support assembly 3 is moved so that the bottom cover moves to the bottom of the sleeve assembly 7, and the bottom cover is aligned with the bottom of the filter cartridge body. The contact is started, and the driving component 4 is started, which drives the rotating conductive member 9 and the elastic linkage component 10 to rotate, and drives the sleeve component 7 to rotate. At the same time, the electromagnet 11 is started, and the electromagnet 11 is energized to generate magnetic attraction and adsorb the upper end of the bottom support component 3 downward, so that the sleeve component 7 drives the outer filter cartridge body and the bottom cover that are aligned and in contact with the bottom to rotate together, and the forming welding end 6 is started to weld toward the contact circumference of the rotating filter cartridge body and the bottom cover to complete the forming welding. After the welding is completed, the bottom support component 3 is removed, and the electromagnet 2 136 in the distribution and connection component 13 is started at the same time, and the electromagnet 136 is energized to generate magnetic force and magnetically attract the magnetic ring 134 downward, so that the conduction hole 133 is opened to bypass, and the compressed air in the energy storage compression component 14 is automatically emptied, and the spring 4 144 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.

[0023] 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.

[0024] 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.

[0025] Embodiment 2: When the sleeve connection of the filter cartridge body and the tensioning auxiliary fixation 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 base support assembly 3 is moved to align the bottom cover, the detection part 16 is synchronously driven to move and contact the filter cartridge body outside the sleeve assembly 7, and the driving assembly 4 is used to realize the rotation of the sleeve assembly 7, and drive the external tensioned sleeved filter cartridge body to rotate, and start the defect detection mechanism in the detection part 16 to perform defect detection on the outside of the fully tensioned filter cartridge body, and identify whether there are defects such as cracks at the welding part of the filter cartridge body under sufficient tensioning pressure, and after completing the circumferential welding of the filter cartridge body and the bottom cover during the rotation process, the newly welded weld detection is completed at the same time to complete the synchronous quality inspection.

[0026] First, by reusing the base support assembly 3, the sleeve assembly 7 and the tensioning assembly 8, and cooperating with the detection part 16 that moves with the base support assembly 3, during the forming and welding process, the detection part 16 is moved to the outside of the filter cartridge body. On the one hand, in cooperation with the tensioning pressure of the tensioning assembly 8, 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 promptly interrupted. On the other hand, while the sleeve assembly 7 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.

[0028] By energizing the electromagnet 11 to generate magnetic attraction, and cooperating with the magnetic sheet 34 for magnetic attraction, the bottom cover placed above the magnetic sheet 34 is magnetically clamped to the bottom of the sleeve assembly 7, and the bottom support assembly 3 cooperates with the electric push rod 2 31 and the moving assembly 2 to achieve left and right and up and down movement, so as to realize 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 body after movement, and on the other hand, it is moved away after forming and welding, leaving space for the metal filter cartridge to be collided and pushed out by the energy storage compression assembly 14 after welding and forming. The tray 33 can rotate freely on the top of the top seat 32 through the rotating rod 35, so that the tray 33 after magnetic attraction can rotate synchronously with the sleeve assembly 7.

The welding end of the formed welding end 6 is telescopic and adjustable to adapt to and approach the outer side of the sleeve assembly 7 to complete the welding process.

[0039] The outer side of the bottom support assembly 3 is fixedly connected with a detection unit 16 , which includes a vertical plate and a metal flaw detection structure arrayed and fixed on the vertical plate. The formed welding end 6 and the detection unit 16 are distributed on the left and right sides of the sleeve assembly 7 .

[0041] The working principle and use process of the present invention are as follows: when in use, the filter cartridge body to be formed and welded is taken out, and is sleeved on the outer side of the sleeve assembly 7, so that the top of the filter cartridge body contacts the limit plate 73, and the sleeved filter cartridge body is randomly pushed upward, and the sleeve assembly 7 is driven to move upward synchronously. While compressing the spring 102, the cylinder 71 moves upward along the outer side of the fixing rod 101, and simultaneously pushes 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 spring 144, completing the front-stage energy storage compression, and the connecting port 76 in the sleeve assembly 7 is aligned and connected with the side port 104 after movement, and at the same time, as the cylinder 71 moves upward, it also drives the top connecting opening and closing ring 15 to move upward, so that the connecting opening and closing ring 15 is sleeved onto The air supply assembly 12 is started at this time, and the air pump 122 enters the connecting sleeve 121 through the connecting frame 123 and the connecting pipe 124, and is input into the distribution chamber 93 through the through hole 1 94. The pressurized air entering the distribution chamber 93, on the one hand, passes through the through cavity 105, the side opening 104, the connecting opening 76, and the annular cavity 75 into the side groove 74, pushing the tensioning assembly 8 to move, stretching the spring 1 83 and tightening and fixing it from the inside of the filter cartridge body. On the other hand, part of the pressurized air entering the distribution chamber 93 passes through the through hole 2 95, the conducting hole 133, the middle hole 134, and the through hole 135. 152 and the side pipe 137 are input into the fixed pipe 141, and the pressurized air input into the fixed pipe 141 replaces the compression of the filter cartridge body on the push block 145, and the internal pressure air is used to compress the spring four 144 to complete the pneumatic energy storage, and then the spring two 102 in the upper elastic linkage assembly 10 of the sleeve assembly 7 is released to elastically reset, and the sleeve assembly 7 is pushed to move down and reset, and the connecting port 76 is sealed. At the same time, the connecting opening and closing ring 15 is removed from the distribution connecting assembly 13, and as the magnetic ring 134 is reset, the distribution connecting assembly 13 is resealed, and the energy storage compression assembly 14 maintains the energy storage state, and the bottom cover to be assembled and welded is placed on the bottom support assembly 3, and the bottom support assembly 3 is moved so that the bottom cover moves to the bottom of the sleeve assembly 7, and the bottom cover is aligned with the bottom of the filter cartridge body. The drive assembly 4 is started to drive the rotating conductive member 9 and the elastic linkage assembly 10 to rotate, and the sleeve assembly 7 is driven to rotate. At the same time, the electromagnet 11 is started. The 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 outer filter cartridge body and the bottom cover that are aligned and in contact with the bottom to rotate together. The forming welding end 6 is started to weld toward the contact circumference of the rotating filter cartridge body and the bottom cover to complete the forming welding. After the welding is completed, the bottom support assembly 3 is removed, and the electromagnet 2 136 in the distribution and connection assembly 13 is started at the same time. The electromagnet 136 is energized to generate magnetic force and magnetically attract the magnetic ring 134 downward, so that the conduction hole 133 is opened to bypass, and the compressed air in the energy storage compression assembly 14 is automatically emptied, and the spring 4 144 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 outer side of the sleeve assembly 7 is impacted and pushed out, thereby completing the automatic discharging; When the sleeve connection of the filter cartridge body and the tensioning and auxiliary fixation 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 base support assembly 3 is moved to align the bottom cover, the detection part 16 is synchronously driven to move and contact the filter cartridge body outside the sleeve assembly 7, and the driving assembly 4 is used to realize the rotation of the sleeve assembly 7, and drive the external tensioned sleeved filter cartridge body to rotate, and start the defect detection mechanism in the detection part 16 to perform defect detection on the outside of the fully tensioned filter cartridge body, and identify whether there are defects such as cracks at the welding part of the filter cartridge body under sufficient tensioning pressure, and after completing the circumferential welding of the filter cartridge body and the bottom cover during the rotation process, the newly welded weld detection is completed at the same time to complete the synchronous quality inspection.
