Description

Technical Field

[0001] The present application relates to the technical field of filter processing equipment, and in particular to a punching device and a processing method for filter processing. Background Art

[0002] The filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency point of a specific frequency in the power line or the frequency outside the frequency point, and obtain a power signal of a specific frequency, or eliminate the power signal after a specific frequency. The filter includes a shell and several components inside the shell. In the actual production process, several panels of the shell need to be punched separately before assembly.

[0003] In the related art, the punching device for the panel of the filter housing usually includes a processing platform and a punching mechanism above the processing platform. The surface of the processing platform is provided with punching holes. When in use, the panel is placed on the processing platform, and then the punching mechanism is used to punch the panel. The waste after punching falls from the punching holes to achieve separation.

[0004] The above-mentioned related technologies have the following defects: when the panel is thin, the panel is easily deformed during the punching process, affecting the surface quality. This not only reduces the consistency and reliability of the product, but also increases the cost and time of subsequent processing. Therefore, there is an urgent need for a punching device and technical solution that can effectively solve the problem of panel deformation. Summary of the invention

[0005] In order to improve the apparent quality stability during panel processing, the present application provides a punching device and processing method for filter processing.

[0006] In the first aspect, the present application provides a punching device for filter processing, which adopts the following technical solution: A punching device for filter processing includes a processing platform and a punching mechanism above the processing platform, wherein the processing platform surface is provided with punching holes, and a flattening mechanism is also provided above the processing platform, wherein the flattening mechanism includes a flattening bar and a flattening drive assembly, wherein the flattening drive assembly is connected between the processing platform and the flattening bar and is used to press the flattening bar above a panel to be punched.

[0007] By adopting the above technical solution, the panel is pressed by the flattening strip, so that the state of the panel during the punching process is more stable, the deformation problem caused by the thin thickness is reduced, and the apparent quality stability of the panel during the processing is significantly improved.

[0008] Preferably, the leveling drive assembly includes a pull rope, the leveling strip is provided with a force application hole, and the pull rope passes through the force application hole.

[0009] By adopting the above technical solution, the flattening strip is pressed down by passing the pull rope through the force-applying hole on the flattening strip, making the operation easier and safer, and avoiding the potential safety hazards caused by manually reaching into the stamping area. At the same time, this method can ensure that the flattening strip applies pressure evenly, reduce the problem of panel deformation caused by excessive local pressure, and improve the apparent quality stability during the panel processing process.

[0010] Preferably, the flattening strips are arranged in a pair, and the processing platform is provided with positioning rings on both sides of each flattening strip, the two pairs of positioning rings are respectively located on both sides of the punching hole, and the pull rope passes through the flattening strips and the positioning rings to realize the series connection of the two flattening strips.

[0011] By adopting the above technical solution, the design of a pair of leveling strips with positioning rings and pull ropes can ensure that the two leveling strips apply pressure to the panel more evenly, avoiding the problem of panel deformation caused by excessive pressure at a certain point. In addition, the series design of the pull rope makes the operation easier. Only one pull rope needs to be pulled to achieve the simultaneous pressing of the two leveling strips, which improves work efficiency.

[0012] Preferably, the processing platform is provided with positioning piles, and both ends of the pull rope are wound around the outer side walls of the positioning piles.

[0013] By adopting the above technical solution, this method can not only ensure that the pull rope will not slip during the tensioning process, thereby improving the safety and reliability of the operation, but also make the pull rope more firmly fixed on the positioning pile, thereby ensuring that the pressure of the flattening strip on the panel is evenly distributed, preventing panel deformation caused by excessive local pressure, and improving the apparent quality stability after punching.

[0014] Preferably, the flattening strips are arranged as a pair, and both flattening strips are provided with a cross bar and an insertion hole, the cross bar is inserted into the insertion hole of the other flattening strip, and the bottom wall of the cross bar and the bottom wall of the flattening strip are located in the same plane.

[0015] By adopting the above technical solution, the design of a pair of flattening strips and their crossbars can more comprehensively press the periphery of the punching position of the panel, ensuring that the surface quality around the punching position is more stable. Specifically: The frame structure formed by the combination of the crossbars and the leveling strips can fully exert pressure on the surrounding area during the punching operation to prevent deformation of the panel due to local uneven force.

[0016] The flush design of the flat strip and the bottom surface of the crossbar makes the entire contact area larger and the pressure distribution more even, reducing the indentation problem caused by excessive local pressure and further improving the overall surface quality and stability of the panel.

[0017] Preferably, the two flattening strips and the cross bar form a flattening frame, a dustproof sleeve is arranged above the flattening frame, a clearance hole is arranged on the top of the dustproof sleeve, the clearance hole is coaxial with the punching hole and the diameter of the clearance hole is larger than the diameter of the punching hole.

[0018] By adopting the above technical solution, the flat frame formed by the two flat strips and the crossbar can more comprehensively compress the circumference of the punching position of the panel, thereby making the apparent quality stability of the circumferential position of the punching position higher. The design of the dust sleeve not only prevents the debris generated during the punching process from flying around, but also produces an air pressure gain effect when the punching head enters, further increasing the pressure range on the panel, ensuring that the panel is more evenly stressed during the punching process, reducing the risk of deformation, and improving the apparent quality.

[0019] Preferably, flexible dustproof scales are circumferentially arranged inside the clearance hole, and the inner edges of a plurality of the dustproof scales form a dustproof hole, and the diameter of the dustproof hole is smaller than the diameter of the punching head of the punching mechanism.

[0020] By adopting the above technical solution, the design of the dustproof scales makes it possible for several dustproof scales to be pressed down and bent when the punch head enters the dustproof sleeve, but still maintain a certain sealing effect. This not only reduces the problem of debris flying around during the punching process, but also further increases the air pressure inside the dustproof sleeve, enhances the pressure effect of the air pressure on the panel, and improves the stability of the panel during the punching process, thereby ensuring higher surface quality.

[0021] Preferably, adjacent dustproof scales are at least partially overlapped.

[0022] By adopting the above technical solution, adjacent dustproof scales are at least partially overlapped, which can further improve the sealing effect at the give way hole, so that the air pressure inside the dustproof sleeve can be better maintained during the stamping process, the pressure effect of the air pressure on the panel can be improved, and debris can be prevented from splashing during the stamping process, ensuring that the surface quality of the punching part of the panel is more stable.

[0023] Preferably, the dustproof sleeve comprises a pair of dustproof half-cylinders, the two dustproof half-cylinders are respectively connected to two flat strips, and a sealing strip is arranged between the two dustproof half-cylinders.

[0024] By adopting the above technical solution, the dustproof sleeve includes a pair of dustproof half-cylinders, the two dustproof half-cylinders are respectively connected to two flat strips, and a sealing strip is arranged between the two dustproof half-cylinders. This design can achieve the docking and installation of the two dustproof half-cylinders during the placement of the two flat strips, and during the stretching and tightening process, on the one hand, the flat strips can be forced downward, and on the other hand, the two flat strips can be brought closer to each other, so that the two dustproof half-cylinders can be tightly attached during the tightening process, thereby improving the sealing effect of the dustproof sleeve. This not only helps prevent the debris generated during the stamping process from flying around, but also further enhances the pressure effect of the air pressure on the panel, ensures the stability of the panel during the punching process, and reduces deformation and surface quality problems.

[0025] In a second aspect, the present application provides a filter processing method based on a punching device, which adopts the following technical solution: A filter processing method based on a punching device, in which a pull rope is in a relaxed state in an initial state. When a panel to be punched is placed at a processing position, two flat strips are placed above the panel. After the pull rope is tightened, the pull rope is wound around the outside of a positioning pile, and then a punching mechanism is started to punch the panel.

[0026] By adopting the above technical solution, it can ensure that the panel is firmly fixed on the processing platform by the flat strip before punching, avoiding the deformation problem caused by the thin thickness of the panel. Specifically: In the initial state, the drawstring is in a loose state, which makes it easier for the operator to place the panel to be punched in the correct position; Place two flat strips on top of the panel and press them onto the panel by tightening the drawstrings, so that both sides of the panel are subjected to uniform pressure, which improves the stability of the panel and reduces the possibility of deformation; The design of winding the pull rope around the outside of the positioning pile is not only convenient for operation, but also ensures that the tension of the pull rope is more balanced, further improving the compression effect on the panel; Finally, the punching mechanism is started to perform the punching operation. During the entire process, the panel is always in a stable pressure state, thus ensuring the consistency and reliability of the punching quality and surface quality.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use the leveling strips and leveling drive components in the leveling mechanism to apply pressure to the panel, making it more stable during the punching process, reducing deformation and improving the stability of the surface quality; 2. The flattening strip is pressed down by a pull rope, which is safer than manual operation and avoids the risk of direct contact with the stamping area; 3. The pull rope passes through the positioning ring to connect the two leveling strips in series, ensuring that the pressure of the two leveling strips is evenly distributed, avoiding the indentation problem caused by uneven pressure of a single leveling strip.

[0030] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0031] The inventor of the present application found that the panel of the filter housing is easily deformed during the punching process, which affects the surface quality. Therefore, the present application mainly adopts the following technical solutions: Example Reference Figure 1 and Figure 2In order to improve the apparent quality stability of the panel during the punching process, the embodiment of the present application provides a punching device for filter processing, including a square processing platform 1, and a punching mechanism 11 is installed above the processing platform 1 through a bracket. A flattening mechanism 2 is also provided on the surface of the processing platform 1, and the flattening mechanism 2 includes a pair of flattening bars 21, a pair of cross bars 22 and a flattening drive assembly 23. The flattening drive assembly 23 is connected between the processing platform 1 and the flattening bar 21 to press the flattening bar 21 above the panel to be punched. The flattening bar 21 and the cross bar 22 can be made of metal materials, such as stainless steel or aluminum alloy, to ensure sufficient strength and durability.

[0032] Reference Figure 3 , the surface of the processing platform 1 is provided with a punching hole 10, and the panel is placed above the punching hole 10, so that the punching mechanism 11 can punch the panel, and the waste after punching falls from the punching hole 10 to achieve separation. Each leveling bar 21 is provided with a force hole 210, and the number and position of the force holes 210 can be set according to actual conditions to ensure uniform force. The processing platform 1 is provided with positioning rings 231 on both sides of each leveling bar 21, and two pairs of positioning rings 231 are respectively located on both sides of the punching hole 10. The leveling drive assembly 23 includes a pull rope 232, and the pull rope 232 can be made of high-strength nylon rope or other materials with sufficient strength and durability. In this embodiment, a pull rope 232 is selected to pass through the force holes 210 on the two leveling bars 21 and the positioning ring 231 on the processing platform 1 in a U shape. The two ends of the pull rope 232 are finally merged and tightened, so that the leveling bar 21 can press down on the panel. The pull rope 232 passes through the leveling strip 21 and the positioning ring 231 to realize the series connection of the two leveling strips 21. In this way, it can be ensured that the two leveling strips 21 remain parallel during the pressing process, avoiding uneven pressure distribution caused by uneven force on one side.

[0033] The surface of the processing platform 1 is also fixed with positioning piles 233. After the pull rope 232 is tightened, the two ends are merged and wrapped around the positioning piles 233. The actual number of winding circles is selected as needed to achieve the tension of the pull rope 232, so as to achieve stable pressing on the panel during the subsequent punching process.

[0034] Reference Figure 3 The two flat strips 21 and the two cross bars 22 form a square flat frame. To further improve the safety and environmental protection during the punching process, a dust sleeve 3 is arranged above the flat frame. A clearance hole 30 is arranged on the top of the dust sleeve 3. The clearance hole 30 is coaxial with the punching hole 10 and the diameter of the clearance hole 30 is larger than the diameter of the punching hole 10. One of the functions of the dust sleeve 3 is to capture the debris generated during the punching process to prevent it from splashing around and polluting the environment.

[0035] In addition, refer to Figure 4, flexible dustproof scales 31 are circumferentially arranged inside the clearance hole 30, and the inner edges of several dustproof scales 31 form a dustproof hole 32, and the diameter of the dustproof hole 32 is smaller than the diameter of the punch head 111 of the punching mechanism 11. In the process of the punch head 111 entering the dustproof sleeve 3, several dustproof scales 31 are pressed down and bent, but can still be sealed to a certain extent, thereby further improving the air pressure increase after the punch head 111 enters the dustproof sleeve 3, and increasing the pressure effect of the air pressure on the panel. There is at least a partial overlap between adjacent dustproof scales 31 to further improve the sealing effect at the clearance hole 30. This design not only improves the sealing performance of the dustproof sleeve 3, but also effectively prevents small debris from leaking out of the gap.

[0036] Reference Figure 5 The flattening strips 21 correspond to the crossbars 22 one by one, and each flattening strip 21 is provided with an insertion hole 240. The end of the crossbar 22 away from the flattening strip 21 extends to form an insertion block 24 to be inserted into the insertion hole 240 of another flattening strip 21, so that when both flattening strips 21 are pressed down, the crossbar 22 can further drive the interaction between the two flattening strips 21 to maintain the overall force balance. The design of the crossbar 22 and the insertion hole 240 can not only enhance the rigidity of the flattening strip 21, but also more comprehensively compress the circumference of the punching position of the panel, further improving the apparent quality stability of the punching position.

[0037] Therefore, the dustproof sleeve 3 in this embodiment includes a pair of dustproof half-cylinders 33, the two dustproof half-cylinders 33 are respectively connected to the two flat strips 21, and a sealing strip 34 is provided between the two dustproof half-cylinders 33 to further improve the sealing performance of the dustproof sleeve 3. The advantage of such a design is that the two dustproof half-cylinders 33 can be docked and installed during the placement of the two flat strips 21, and during the stretching and tightening process, on the one hand, the flat strips 21 can be forced downward, and on the other hand, the two flat strips 21 can be brought closer to each other, so that the two dustproof half-cylinders 33 can be closely fitted during the tightening process, thereby improving the overall sealing effect of the dustproof sleeve 3.

[0038] In other embodiments, the processing platform 1 may be provided with multiple groups of positioning rings 231, each group of positioning rings 231 having different positions. For example, the positioning ring 231 may be provided between the two flat strips 21, so that the two flat strips 21 can be more closely attached to each other during the tightening of the pull rope 232, thereby further improving the sealing performance of the two combined dustproof half-tubes 33. The positioning ring 231 may be made of metal or plastic, and the specific selection is based on the convenience and economy of actual operation.

[0039] In other embodiments, in order to improve work efficiency and automation, the leveling drive assembly 23 may also use an electric push rod as a power source. One end of the electric push rod is fixed under the processing platform 1, and the other end is connected to the leveling bar 21 through a connecting rod. The electric push rod can be selected in various forms such as hydraulic cylinders, pneumatic cylinders or electric cylinders, and the specific selection depends on the actual application scenario and budget. For example, for a large production line, a high-power electric cylinder can be selected to ensure sufficient driving force; for a small laboratory, a lightweight pneumatic cylinder can be selected to save space and cost.

[0040] The implementation principle of this embodiment is: by setting the flattening mechanism 2 and pre-pressing the panel with the flattening strip 21, the risk of panel deformation during the punching process can be significantly reduced. Especially when processing thinner panels, the flattening strip 21 has a more obvious effect and can effectively improve the apparent quality and consistency of the product. Compared with the traditional punching method, this embodiment can greatly improve product quality without affecting production efficiency, and reduce the time and cost of subsequent processing.

[0041] In addition, by adding the dust sleeve 3, not only can the debris generated during the punching process be effectively collected to prevent environmental pollution, but the safety of the punching process can also be further improved. At the same time, the air pressure gain mechanism in the dust sleeve 3 helps to further improve the stability of the panel during the punching process, and uses air pressure to apply pressure to the panel during the punching process to supplement the position that cannot be affected by the mechanical pressure range, thereby further reducing the risk of deformation.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
