Description

Technical Field

[0001] The invention belongs to the technical field of housing processing equipment, and in particular relates to a stamping forming 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 a specific frequency point in the power line or frequencies other than the frequency point to obtain a power signal with a specific frequency, or eliminate a power signal with a specific frequency.

[0003] During the processing of the filter housing, stamping is usually performed. In the prior art, there are also many types of stamping equipment, such as a stamping device for processing a 5G base station filter housing that is convenient for material transfer, with application number: CN202022296358.7. The ejector plate is pressed into the inside of the limit groove, and an elastic force is applied to the limit plate by a spring. 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, so that the filter housing can be automatically ejected, thereby improving the working efficiency of the filter housing stamping device; Another example is a shell stamping device for filter cavity production with application number: CN202122038208.0. The upper plate ring is pushed downward by the elasticity of the upper buffer spring, and the upper plate ring pushes the formed product downward, thereby separating the finished product from the upper stamping plate. The lower buffer spring pushes the top of the finished product out of the stamping groove through the lower plate ring, making it convenient for users to take it. This solves the problem that the existing stamping device cannot automatically demold, making it inconvenient for users to take out the completed workpiece, affecting the user's work efficiency.

[0004] However, in actual application, the above equipment still has some shortcomings: First, although the equipment is designed with the function of ejecting the formed workpiece for easy unloading, the formed workpiece sometimes adheres to the punch head, which requires the operator to manually remove the workpiece from the punch head. This operation process is not only time-consuming and labor-intensive, but also the staff operates directly on the stamping component, which is also highly dangerous; secondly, in production practice, in order to facilitate subsequent assembly, the filter housing needs to be opened with the help of other stamping equipment after the stamping is completed, which makes the production process of the filter housing complicated and cannot realize the integrated molding processing of the housing, thereby significantly reducing production efficiency; in addition, the equipment cannot realize continuous processing of the workpiece, and the picking and placing and stamping processes cannot be carried out simultaneously, resulting in a lot of time waste. Summary of the invention

[0005] 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.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Please refer to the attached Figure 1-Figure 16 As shown, this embodiment provides a stamping forming device, including a device body 1, and a mounting chamber 3 is opened on the device body 1; 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; A turntable 4 is rotatably mounted in the mounting chamber 3; and an auxiliary mechanism 5, the auxiliary mechanism 5 being arranged on the turntable 4; 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 .

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Next, please refer to Figure 11-Figure 15 The stamping part 21 includes a hydraulic electric push rod 211, which is fixedly installed on the upper end of the equipment body 1. A lifting seat 212 is installed at the telescopic end of the hydraulic electric push rod 211. 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 of the stamping top seat 215. A pressure block 217 is connected to the side of the lifting seat 212.

[0029] In this embodiment, the staff first places the workpiece to be stamped on the stamping base 51 located in the left front. Then, the servo motor starts to work and drives the turntable 4 to rotate, and the rotation angle is one hundred and twenty degrees. When the workpiece rotates to the position directly below the stamping mechanism 2, the hydraulic electric push rod 211 is controlled to start to extend. The extension of the hydraulic electric push rod 211 drives the lifting seat 212 to move downward, and the descent of the lifting seat 212 will drive the telescopic rod 213, the stamping top seat 215 and the pressure 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 fully 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 begins to contract and squeezes the strong spring 214. At the same time, the lifting seat 212 continues to drive the pressing block 217 and the abutment portion 23 to move downward to ensure the smooth progress of the stamping process.

[0030] It should be noted that the servo motor is installed at the bottom 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 each rotation angle is 120 degrees. The specific position and structure of the servo motor are not shown in the figure.

[0031] Next, please refer to Fig.16 The resistance part 23 includes a hollow cylinder 231, which is fixedly connected to the lifting seat 212, and a push rod 232 is inserted at the lower end of the hollow cylinder 231, and a first compression spring 233 is connected to the upper end of the push rod 232, and the upper end of the first compression spring 233 is fixedly connected to the inner wall of the hollow cylinder 231.

[0032] Please refer again Figure 6 and Figure 7 The punching portion 52 includes a slide seat 521, which is fixedly connected to the turntable 4. A movable seat 522 is slidably connected to the slide seat 521. A punching head 523 is fixedly installed on the side of the movable seat 522, and the punching head 523 passes through the stamping base 51. A slide groove 524 is provided on the slide seat 521. A connecting rod 525 is slidably inserted in the slide groove 524, and one end of the connecting rod 525 is fixedly connected to the movable seat 522. A second compression spring 526 is fixedly connected between the connecting rod 525 and the slide groove 524. A rotating roller 527 is rotatably arranged on the movable seat 522.

[0033] In this embodiment, as the pressing block 217 gradually moves downward, a certain resistance force is applied to the rotating roller 527. This resistance force will cause the two corresponding moving seats 522 to slide in opposite directions along the sliding seat 521. When the moving seat 522 starts to move, it will drive the connecting rod 525 to shrink into the slide groove 524, and squeeze the second compression spring 526 in the process. As the moving seat 522 moves, the punching head 523 will also penetrate into the stamping base 51 to perform a punching operation on the workpiece. After the punching operation is completed, the waste generated will remain in the through hole 216 on the stamping top seat 215, thereby completing the entire stamping process.

[0034] Please refer again Figure 8-Figure 10 The blocking portion 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 at one end of the first cylinder 531, a baffle 533 is fixedly connected at one end of the second piston rod 532, a second piston plate 539 is fixedly connected at 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 also fixedly connected to the top surface of the turntable 4, and the air storage shell 535 is connected to the first cylinder 531 by an air supply pipe, a third piston rod 536 is inserted at 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, and a third piston plate 538 is fixedly connected to the other end of the third piston rod 536, wherein the elasticity of the first compression spring 233 is greater than the elasticity of the fourth compression spring 537.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In this embodiment, after the stamping process is completed, the servo motor is started to drive the turntable 4 to rotate again, so that it rotates one hundred and twenty degrees. As the turntable 4 rotates, the positions of the three stamping bases 51 are adjusted. When the force block 543 at the lower end of the stamping base 51 moves to the position of the boss 545, the force block 543 will gradually move upward under the action of the boss 545. The upward movement of the force block 543 will drive the movable rod 542 and the top plate 541 to move upward together, thereby squeezing the fifth compression spring 544. By utilizing the upward movement of the top plate 541, the stamped workpiece can be lifted from the stamping base 51, thereby facilitating the unloading 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.

[0039] Secondly, please also refer to Figure 13-Figure 15 The slag discharge part 22 includes a hollow shell 221, which is fixedly connected to the equipment body 1. A first piston plate 222 is arranged in the hollow shell 221. A first piston rod 223 is fixedly connected to the bottom surface of the first piston plate 222, 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 pressure 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.

[0040] In this embodiment, 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 together. This action causes the air in 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, thereby realizing the function of automatic slag discharge.

[0041] A forming process for processing a filter housing, applied to the above-mentioned stamping forming device, comprises the following steps: Step 1: The staff places the workpiece on the stamping base 51, and the servo motor drives the turntable 4 to rotate 120 degrees to move the workpiece under the stamping mechanism 2; Step 2: The hydraulic electric push rod 211 drives the punching seat 215 to descend, punches the workpiece through the punching seat 215, and drives the punching part 52 to punch the workpiece at the same time, and the punching waste falls into the through hole 216; 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, the compressed air blows out the waste in the through hole 216 through the exhaust pipe 224; Step 4: After the stamping is completed, the servo motor drives the turntable 4 to rotate 120 degrees again, and the top plate 541 lifts the stamped workpiece for unloading, thereby realizing synchronous stamping, loading and unloading.

[0042] The working principle of the present invention is: When the workpiece moves to the bottom of the stamping mechanism 2, the hydraulic electric push rod 211 is controlled 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 pressure 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 fully inserted into the stamping base 51 and the stamping is completed, the hydraulic electric push rod 211 continues to extend. At this time, the stamping top seat 215 cannot be further lowered, and the telescopic rod 213 begins to contract, squeezing the strong spring 214. The lifting seat 212 continues to drive the pressure block 217 and the resistance part 23 to move downward; as the pressure block 217 descends, pressure is applied to the rotating roller 527, so that the corresponding two moving seats 522 slide in opposite directions along the slide seat 521. The movement of the movable seat 522 drives the connecting rod 525 to shrink into the slide groove 524 and compress the second compression spring 526 . The movement of the movable seat 522 also drives the punching head 523 to penetrate into the punching base 51 to punch the workpiece.

[0043] When the abutment portion 23 drops to a specific position, it will press down the horizontal 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 the third compression spring 534. The compressed air then enters the first cylinder 531 along the air delivery pipe, pushing the second piston plate 539 to move, and the second piston plate 539 simultaneously drives the second piston rod 532 and the baffle plate 533 to move until the baffle plate 533 is in close contact with the side wall of the stamping top seat 215. After the baffle plate 533 is in close contact with the side wall of the stamping top seat 215, as the lifting seat 212 continues to drop, the third piston rod 536 will not be able to drop further, and the top rod 232 is forced to shrink into the hollow cylinder 231 and squeeze the first compression spring 233. After the 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 the elasticity of the fourth compression spring 537, the first compression spring 233 will be reset first, pushing the push rod 232 to extend from the hollow cylinder 231. At this time, the second piston plate 539 will not be reset, and the baffle 533 is still close 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 stamping top seat 215. As the lifting seat 212 continues to rise, when the push 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 to move upward. At this time, the second piston plate 539 also gradually loses pressure, and the reset force generated by the third compression spring 534 drives the second piston rod 532 and the baffle 533 to reset.

[0044] After the stamping is completed, the servo motor is started to drive the turntable 4 to rotate 120 degrees, and the positions of the three stamping bases 51 are adjusted as the turntable 4 rotates. When the force block 543 at the lower end of the stamping base 51 moves to the boss 545, it gradually moves upward due to the resistance of the boss 545. The force block 543 moves upward to drive the movable rod 542 and the top plate 541 to move upward, and squeeze the fifth compression spring 544. The top plate 541 is used to lift the stamped workpiece from the stamping base 51 for easy unloading. This structural design allows stamping, loading and unloading to be performed simultaneously, saving time, and there is no need to place the workpiece under the stamping mechanism 2, which is safer and more reliable.

[0045] When the lifting seat 212 drives the pressure block 217 to move upward, the pressure block 217 drives the first piston rod 223 and the first piston plate 222 to move upward and compress the air in the hollow shell 221. The compressed air then enters the through hole 216 along the exhaust pipe 224, blows out the punching waste remaining in the through hole 216, and completes automatic slag discharge.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
