Description

Technical Field

[0001] The present invention belongs to the technical field of shell processing equipment, and particularly relates to a stamping device and a forming process for processing a filter housing. Background Art

[0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out specific frequency points in the power line or frequencies outside that frequency point, obtain a power signal with a specific frequency, or eliminate the power signal after a specific frequency.

[0003] During the processing of the filter housing, it is usually formed by stamping. In the prior art, there are also many types of stamping equipment. For example, a stamping device for processing a 5G base station filter housing that is convenient for material transfer with the application number: CN202022296358.7. By pressing the ejector plate into the limit groove, a spring applies an elastic force to the limit plate, the limit plate drives the ejector rod to move upward, and the ejector rod drives the ejector plate to eject the filter housing inside the stamping groove, realizing the automatic ejection of the filter housing, and improving the working efficiency of the filter housing stamping device;

[0004] Another example is a stamping device for a filter cavity housing production with the application number: CN202122038208.0. The elastic force of the upper buffer spring pushes the upper plate ring downward, and the upper plate ring pushes the formed product downward, so that the finished product is separated from the upper stamping disc. The lower buffer spring pushes the top of the finished product out of the stamping groove through the lower plate ring, which is convenient for the user to take. This solves the problem that the existing stamping device cannot be automatically demolded, is inconvenient for the user to take out the processed workpiece, and affects the working efficiency of the user.

[0005] However, in practical applications, the above devices still have some deficiencies: First, although the device is designed with the function of ejecting the formed workpiece for easy blanking, the formed workpiece sometimes adheres to the stamping head, which requires the operator to manually remove the workpiece from the stamping head. This operation process is not only time-consuming and laborious, but also the staff operates directly on the stamping component, and the risk is relatively high; Second, in production practice, in order to facilitate subsequent assembly, the filter housing needs to be processed by other stamping equipment for punching after stamping, which makes the production process of the filter housing complicated, unable to realize the integrated forming processing of the housing, thus significantly reducing the production efficiency; In addition, the device cannot realize continuous processing of workpieces, and the processes of taking and placing and stamping cannot be synchronized, resulting in a waste of a lot of time. Summary of the Invention

[0006] The purpose of the present invention is to provide a stamping forming device and a forming process for filter housing processing, which can complete the main forming steps in a single processing process without the need for additional hole opening processing with the help of other equipment, and also enable the three processes of loading, stamping and unloading to be carried out simultaneously, greatly reducing waiting time and improving work efficiency.

[0049] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0050] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0051] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in a preferred implementation manner" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0052] Furthermore, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0053] Please refer to the attached Figures 1 - 16 As shown, this embodiment provides a stamping and forming device, including an equipment main body 1, and an installation chamber 3 is provided on the equipment main body 1;

[0054] A stamping mechanism 2, which is disposed at the upper end of the equipment body 1, and includes a stamping portion 21, which is mounted on the equipment body 1, and is provided with a slag discharge portion 22 and a resistance portion 23;

[0055] A turntable 4 is rotatably mounted in the mounting chamber 3;

[0056] and an auxiliary mechanism 5, the auxiliary mechanism 5 being arranged on the turntable 4;

[0057] The auxiliary mechanism 5 includes a stamping base 51 , which is arranged on the turntable 4 in a ring-shaped distribution. Each stamping base 51 is provided with a punching portion 52 , a blocking portion 53 and a material-lifting portion 54 .

[0058] In this embodiment, the device body 1 is the basic structure of the entire device, and all other components are installed on this body. The installation chamber 3 is located at the upper end of the device body 1 for installing other components. The stamping mechanism 2 is a main working component located at the upper end of the device body 1 and is responsible for the actual stamping action.

[0059] The punching mechanism 2 includes the following parts: a punching part 21, a slag removal part 22 and a resistance part 23. The punching part 21 is the core part of the punching mechanism 2, and is used to directly apply pressure to the workpiece to form a desired shape. The slag removal part 22 is used to remove waste or excess material during the punching process. The resistance part 23 is a part that squeezes other components and is used to assist processing.

[0060] The turntable 4 is a rotatable disc-shaped structure installed in the installation chamber 3 of the equipment body 1, and is used to carry other components and move them to different positions. The auxiliary mechanism 5 is arranged on the turntable 4 to assist other actions in the stamping process. The stamping base 51 is distributed in a ring shape on the turntable 4. The punching part 52 is used to punch holes in the workpiece. The blocking part 53 is used to prevent the workpiece from being incorrectly moved or positioned during the stamping process. The ejector part 54 is used to push the workpiece out to facilitate unloading.

[0061] In summary, the device can continuously perform stamping and forming on the workpiece through the rotation of the turntable 4 and the action of the stamping mechanism 2. The auxiliary mechanism 5 on the turntable 4 can help complete auxiliary actions such as punching, blocking and ejecting to improve the forming efficiency and accuracy.

[0062] Next, please refer to Figures 11 - 15, the stamping section 21 includes a hydraulic electric push rod 211. The hydraulic electric push rod 211 is fixedly installed at the upper end of the equipment main body 1. The telescopic end of the hydraulic electric push rod 211 is equipped with a lifting seat 212. The bottom surface of the lifting seat 212 is connected with a telescopic rod 213. A strong spring 214 is arranged in the telescopic cavity of the telescopic rod 213. The lower end of the telescopic rod 213 is fixedly connected with a stamping top seat 215. A through hole 216 is opened on the side surface of the stamping top seat 215. A pressing block 217 is connected to the side surface of the lifting seat 212.

[0063] In this embodiment, the staff first places the workpiece to be stamped on the stamping base 51 located in the front left. Then, the servo motor starts to work and drives the turntable 4 to rotate. The rotation angle is 120 degrees. When the workpiece rotates to the position directly below the stamping mechanism 2, the hydraulic electric push rod 211 is controlled to start extending. The extension of the hydraulic electric push rod 211 drives the lifting seat 212 to move downward. The downward movement of the lifting seat 212 will drive the telescopic rod 213, the stamping top seat 215 and the pressing block 217 to move downward synchronously. Through the close cooperation between the stamping top seat 215 and the stamping base 51, the workpiece is stamped. After the stamping top seat 215 is completely inserted into the stamping base 51 and the stamping task is completed, the hydraulic electric push rod 211 continues to extend. At this time, the stamping top seat 215 can no longer move downward, and the telescopic rod 213 starts to contract and will squeeze the strong spring 214. At the same time, the lifting seat 212 continues to drive the pressing block 217 and the abutting part 23 to move downward to ensure the smooth progress of the stamping process.

[0064] It should be specifically supplemented and explained that the servo motor is installed at the bottom surface position of the installation chamber 3, and its output end is connected to the turntable 4. The working mode of the servo motor is intermittent rotation, and the rotation angle each time is 120 degrees. The specific position and structure of the servo motor are not shown in the figure.

[0065] Secondly, please refer to again Figure 16 , the abutting part 23 includes a hollow cylinder 231. The hollow cylinder 231 is fixedly connected to the lifting seat 212. A top rod 232 is inserted into the lower end of the hollow cylinder 231. The upper end of the top rod 232 is connected with a first compression spring 233, and the upper end of the first compression spring 233 is fixedly connected to the inner wall of the hollow cylinder 231.

[0066] Please refer to again Figure 6 And Figure 7, the punching part 52 includes a sliding seat 521 which is fixedly connected to the turntable 4. A moving seat 522 is slidably connected to the sliding seat 521. A punching head 523 is fixedly installed on the side of the moving seat 522, and the punching head 523 penetrates through the punching base 51. A chute 524 is formed on the sliding seat 521, and a connecting rod 525 is slidably inserted into the chute 524. One end of the connecting rod 525 is fixedly connected to the moving seat 522. A second compression spring 526 is fixedly connected between the connecting rod 525 and the chute 524. A rotating roller 527 is rotatably arranged on the moving seat 522.

[0067] In this embodiment, as the pressing block 217 gradually moves downward, a certain resistance force will be exerted on the rotating roller 527. This resistance force will cause the two corresponding moving seats 522 to slide along the sliding seat 521 in opposite directions. When the moving seat 522 starts to move, it will drive the connecting rod 525 to contract into the chute 524, and the second compression spring 526 will be compressed during this process. As the moving seat 522 moves, the punching head 523 will also penetrate into the punching base 51 to punch the workpiece. After the punching operation is completed, the generated waste will remain in the through hole 216 on the punching top seat 215, thus completing the entire punching process.

[0068] Please refer to again Figures 8 - 10 , the blocking part 53 includes a first cylinder 531 which is fixedly connected to the turntable 4 by a support rod. A second piston rod 532 is slidably inserted into one end of the first cylinder 531. A baffle 533 is fixedly connected to one end of the second piston rod 532. A second piston plate 539 is fixedly connected to the other end of the second piston rod 532. A third compression spring 534 is also sleeved on the outer wall of one end of the second piston rod 532. An air storage shell 535 is fixedly connected to the top surface of the turntable 4, and the air storage shell 535 is communicated with the first cylinder 531 by an air pipe. A third piston rod 536 is inserted into the upper end of the air storage shell 535, and a cross plate is connected to the upper end of the third piston rod 536. A fourth compression spring 537 is sleeved on the upper end of the third piston rod 536. A third piston plate 538 is fixedly connected to the other end of the third piston rod 536. Among them, the elasticity of the first compression spring 233 is greater than that of the fourth compression spring 537.

[0069] In this embodiment, when the abutment portion 23 drops to a certain position, it will exert downward pressure on the horizontal plate, causing the third piston rod 536 and the third piston plate 538 to move downward, thereby compressing the air in the air storage shell 535. This compression process will also compress the fourth compression spring 537. The compressed air will then enter the first cylinder 531 along the air pipe. After entering, the air will push the second piston plate 539 to move, and the second piston plate 539 will synchronously drive the second piston rod 532 and the baffle plate 533 to move together until the baffle plate 533 is completely attached to the side wall of the stamping top seat 215. After the baffle plate 533 is completely attached to the side wall of the stamping top seat 215, as the lifting seat 212 continues to move downward, the third piston rod 536 will no longer be able to move downward, and the top rod 232 will be subject to the force and shrink into the hollow cylinder 231, and squeeze the first compression spring 233.

[0070] After the stamping process is completed, the hydraulic electric push rod 211 drives the lifting seat 212 to move upward. Since the elasticity of the first compression spring 233 is greater than the elasticity of the fourth compression spring 537, the first compression spring 233 will be reset first, pushing the push rod 232 out of the hollow cylinder 231. At this time, the second piston plate 539 will not be reset, and the baffle 533 is still attached to the side of the stamping top seat 215. The baffle 533 is used to scrape the workpiece from the stamping top seat 215 to prevent the workpiece from rising with the rise of the stamping top seat 215. As the lifting seat 212 continues to move upward, when the push rod 232 no longer resists the cross plate, the fourth compression spring 537 gradually resets, pushing the third piston rod 536 and the third piston plate 538 to move upward. At this time, the second piston plate 539 also gradually loses pressure, and then the reset force generated by the third compression spring 534 drives the second piston rod 532 and the baffle 533 to reset together.

[0071] Please refer again Figure 2 and Figure 5 The top material part 54 includes a top plate 541, which is arranged at the bottom of the inner cavity of the stamping base 51. A movable rod 542 is fixedly connected to the bottom surface of the top plate 541, and the movable rod 542 passes through the bottom surface of the turntable 4. The lower end of the movable rod 542 is fixedly connected to a force block 543. The outer wall of one end of the movable rod 542 is sleeved with a fifth compression spring 544. A boss 545 is also arranged on the bottom surface of the inner cavity of the installation chamber 3, wherein a ball is arranged at the lower end of the force block 543.

[0072] In this embodiment, after the stamping process is completed, the servo motor is started to drive the turntable 4 to rotate again, causing it to rotate by one hundred and twenty degrees. As the turntable 4 rotates, the positions of the three stamping bases 51 are adjusted. When the force-receiving block 543 at the lower end of the stamping base 51 moves to the position of the boss 545, under the action of the boss 545, the force-receiving block 543 gradually moves upward. The upward movement of the force-receiving block 543 drives the movable rod 542 and the top plate 541 to move upward together, thereby squeezing the fifth compression spring 544. By using the upward movement of the top plate 541, the stamped workpiece can be pushed out of the stamping base 51, facilitating the blanking operation. This design not only improves production efficiency but also ensures the smooth removal of the workpiece, making the entire stamping process smoother and more efficient.

[0073] Next, please also refer to Figures 13 - 15 , the slag discharging part 22 includes a hollow shell 221 which is fixedly connected to the equipment main body 1. A first piston plate 222 is arranged inside the hollow shell 221. The bottom surface of the first piston plate 222 is fixedly connected to a first piston rod 223, and the lower end of the first piston rod 223 extends to the outside of the hollow shell 221 and is fixedly connected to the pressing block 217. An exhaust pipe 224 is connected to the hollow shell 221, and the other end of the exhaust pipe 224 is connected to the through hole 216.

[0074] In this embodiment, during the process of the lifting seat 212 driving the pressing block 217 to move upward, the pressing block 217 drives the first piston rod 223 and the first piston plate 222 to move upward together. This action causes the air inside the hollow shell 221 to be compressed. Subsequently, the compressed air enters the through hole 216 along the exhaust pipe 224. In this way, the punching waste remaining in the through hole 216 can be effectively blown out, realizing the function of automatic slag discharging.

[0075] A forming process for processing a filter housing, which is applied to the above-mentioned stamping forming device, includes the following steps:

[0076] Step 1: The worker places the workpiece on the stamping base 51, and the servo motor drives the turntable 4 to rotate by 120 degrees to move the workpiece under the stamping mechanism 2;

[0077] Step 2: The hydraulic electric push rod 211 drives the stamping top seat 215 to descend, stamps the workpiece through the stamping top seat 215, and at the same time drives the punching part 52 to punch the workpiece, and the punching waste falls into the through hole 216;

[0078] Step 3: When the stamping mechanism 2 returns, the baffle 533 scrapes the stamped workpiece off the stamping top seat 215 to prevent the workpiece from rising with the stamping top seat 215. At the same time, compressed air blows the waste in the through hole 216 out through the exhaust pipe 224;

[0079] Step 4: After stamping is completed, the servo motor drives the turntable 4 to rotate 120 degrees again, and the top plate 541 jacks up the workpiece that has completed stamping for blanking, realizing synchronous stamping, loading, and blanking.

[0080] The working principle of the present invention is as follows:

[0081] When the workpiece moves below the stamping mechanism 2, control the hydraulic electric push rod 211 to extend, driving the lifting seat 212 to descend. When the lifting seat 212 descends, the telescopic rod 213, the stamping top seat 215, and the pressing block 217 move downward synchronously, and the workpiece is stamped through the stamping top seat 215 and the stamping base 51. After the stamping top seat 215 is completely inserted into the stamping base 51 and stamping is completed, the hydraulic electric push rod 211 continues to extend. At this time, the stamping top seat 215 cannot descend further, and the telescopic rod 213 begins to contract, squeezing the strong spring 214. The lifting seat 212 continues to drive the pressing block 217 and the abutting portion 23 downward; as the pressing block 217 descends, pressure is applied to the rotating roller 527, causing the two corresponding moving seats 522 to slide along the sliding seat 521 in opposite directions. The movement of the moving seat 522 drives the connecting rod 525 to contract into the chute 524 and squeeze the second compression spring 526. The movement of the moving seat 522 also drives the punching head 523 to penetrate into the stamping base 51 to punch the workpiece.

[0082] When the abutting portion 23 descends to a specific position, it will press down the cross plate, causing the third piston rod 536 and the third piston plate 538 to move downward, compressing the air in the air storage shell 535 and compressing the third compression spring 534. The compressed air then enters the first cylinder 531 along the air pipe, pushing the second piston plate 539 to move. The second piston plate 539 synchronously drives the second piston rod 532 and the baffle 533 to move until the baffle 533 abuts against the side wall of the stamping top seat 215. After the baffle 533 abuts against the side wall of the stamping top seat 215, as the lifting seat 212 continues to descend, the third piston rod 536 cannot descend further, and the ejector rod 232 is forced to contract into the hollow cylinder 231 and squeeze the first compression spring 233. After stamping is completed, the hydraulic electric push rod 211 drives the lifting seat 212 to rise. Since the elasticity of the first compression spring 233 is greater than that of the fourth compression spring 537, the first compression spring 233 will reset first, pushing the ejector rod 232 to extend from the hollow cylinder 231. At this time, the second piston plate 539 will not reset, and the baffle 533 still abuts against the side of the stamping top seat 215, using the baffle 533 to scrape the workpiece off the stamping top seat 215 to prevent the workpiece from rising with the stamping top seat 215. As the lifting seat 212 continues to rise, when the ejector rod 232 no longer exerts pressure on the cross plate, the fourth compression spring 537 gradually resets, pushing the third piston rod 536 and the third piston plate 538 upward. At this time, the second piston plate 539 also gradually loses pressure, and the restoring force generated by the third compression spring 534 drives the second piston rod 532 and the baffle 533 to reset.

[0083] After stamping is completed, start the servo motor to drive the turntable 4 to rotate 120 degrees. As the turntable 4 rotates, the positions of the three stamping bases 51 are adjusted. When the force-receiving block 543 at the lower end of the stamping base 51 moves to the boss 545, it gradually moves upward under the resistance of the boss 545. The upward movement of the force-receiving block 543 drives the movable rod 542 and the top plate 541 to move upward, and compresses the fifth compression spring 544. The workpiece after stamping is ejected from the stamping base 51 by using the top plate 541, facilitating blanking. The design of this structure enables stamping, loading, and blanking to be carried out synchronously, saving time, and there is no need to place workpieces under the stamping mechanism 2, which is safer and more reliable.

[0084] When the lifting seat 212 drives the pressing block 217 to move upward, the pressing block 217 drives the first piston rod 223 and the first piston plate 222 to move upward, and compresses the air in the hollow shell 221. The compressed air then enters the through hole 216 along the exhaust pipe 224, blowing out the residual punching waste in the through hole 216 to complete automatic slag discharge.

[0085] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special description and limitation.
