Description

Technical Field

[0001] This invention relates to the field of speaker grille processing technology, and in particular to a speaker grille forming equipment and forming method. Background Technology

[0002] In the process of manufacturing car audio speaker grilles, stainless steel is usually selected as the raw material. The mesh is processed on the stainless steel raw material by etching. Then, the etched raw material is stamped into shape using a stamping processing device. Traditional stamping devices can only stamp and process one type of speaker grille.

[0003] Prior art CN115846491B discloses a car audio speaker grille processing device, including a speaker grille processing table. A processing groove is formed on the upper part of the processing table, and three speaker grille stamping mechanisms are movably arranged in the processing groove. The stamping die seats on the three speaker grille stamping mechanisms are of different models. A pressure mechanism is also provided in the processing groove. The three speaker grille stamping mechanisms are arranged in a circular array around the pressure mechanism. A drive mechanism for driving the three speaker grille stamping mechanisms is also provided in the speaker grille processing table below the three speaker grille stamping mechanisms. This invention, by using three speaker grille stamping mechanisms on the speaker grille processing table, can stamp different models of car audio speaker grilles. The drive mechanism allows for rapid adjustment of the positions of the three speaker grille stamping mechanisms according to actual needs.

[0004] The above-mentioned device can stamp different models of mesh covers. However, after stamping a mesh cover, the machine must be stopped to remove the finished product and then a new raw material plate must be placed. During the whole process, the stamping mechanism is idle, which greatly reduces the effective working time of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a speaker grille forming equipment and forming method, which solves the problem that after the traditional processing equipment completes the stamping of a grille, it is necessary to stop the machine to remove the finished product and then place a new raw material plate. During the whole process, the stamping mechanism is idle, which reduces the processing efficiency.

[0006] To achieve the above objectives, the present invention provides a speaker grille forming device and forming method, including a worktable and a mounting frame, the mounting frame being fixedly installed on one side of the worktable, and further including a processing component; the processing component includes a rotating seat, a lower stamping die seat, an upper stamping die seat, a hydraulic cylinder, a storage cylinder, a feeding component, and a feeding component. The rotating seat is rotatably connected to the worktable and is disposed on the worktable. The lower stamping die seat is fixedly connected to the rotating seat and is disposed on the rotating seat. The hydraulic cylinder is connected to the mounting frame and is located on the side of the mounting frame near the rotating seat. The upper stamping die seat is disposed on the hydraulic cylinder and connected to the output end of the hydraulic cylinder. The storage cylinder is fixedly connected to the mounting frame. The feeding component is disposed on the storage cylinder. The feeding component is disposed on the worktable.

[0007] The feeding component includes a drive seat, a connecting rod, a limiting seat, and an elastic component. The drive seat is fixedly connected to the rotating seat and is located on one side of the rotating seat. The elastic component is slidably connected to the storage cylinder and is disposed on the storage cylinder. The limiting seat is slidably connected to the storage cylinder. The two ends of the connecting rod are rotatably connected to the elastic component and the limiting seat, respectively.

[0008] The elastic component includes a movable frame, a drive rod, and a return spring. The movable frame is slidably connected to the storage cylinder and is disposed on the storage cylinder. The drive rod is fixedly connected to the movable frame and is located on one side of the movable frame. The two ends of the return spring are respectively connected to the storage cylinder and the movable frame, and the return spring is located inside the storage cylinder.

[0009] The movable frame further includes a first ball bearing, which is rotatably connected to the drive rod and located at one end of the drive rod.

[0010] The storage cylinder has an observation groove, which is disposed on the storage cylinder and extends through the storage cylinder.

[0011] The ejector component includes an ejector rod, a compression spring, and an abutment seat. The ejector rod is slidably connected to the lower stamping die base and is disposed on the lower stamping die base. The two ends of the compression spring are respectively connected to the ejector rod and the lower stamping die base. The abutment seat is fixedly connected to the worktable and is located on the side of the worktable near the rotating seat.

[0012] The ejector rod includes a base, a rod, a lifting plate, and a second ball bearing. The rod is slidably connected to the lower punch die base. The base is fixedly connected to the rod and located at one end of the rod. The lifting plate is fixedly connected to the rod and connected to the compression spring, and is sleeved on the compression spring. The second ball bearing is rotatably connected to the rod and located on the side of the rod away from the base.

[0013] The lower stamping die base has a receiving groove, which cooperates with the base body.

[0014] The processing assembly further includes a positioning component, which includes a cylinder and a positioning seat. The cylinder is connected to the worktable and located inside the worktable. The positioning seat is disposed on the cylinder and connected to the output end of the cylinder. The rotating seat has a positioning groove, which is disposed on the side of the rotating seat near the positioning seat and cooperates with the positioning seat.

[0015] On the other hand, the present invention also includes a method for forming a speaker grille, using the aforementioned speaker grille forming equipment, comprising the following steps:

[0016] The etched stainless steel raw material plates are stacked in the storage cylinder, and the two limit seats of the feeding component are brought close to each other to limit the raw material plates and prevent them from falling.

[0017] The servo motor drives the rotating seat to rotate, which in turn drives the three lower stamping die seats to rotate synchronously. When one of the lower stamping die seats reaches the loading position directly below the storage cylinder, the corresponding drive seat is controlled to push the elastic component to move, so that the connecting rod drives the two limit seats to move away from each other, thereby releasing the limit on the raw material plate and allowing the bottom raw material plate to fall into the lower stamping die seat, thus completing the loading.

[0018] After the material is loaded, the lower stamping die holder carrying the raw material plate is controlled to rotate to the stamping position, and another empty lower stamping die holder is controlled to move to the loading position. The cylinder of the driving positioning component drives the positioning seat to extend and engage with the positioning groove of the rotating seat to achieve positioning.

[0019] After positioning is completed, the hydraulic cylinder is controlled to drive the upper stamping die to move downward, cooperate with the lower stamping die to stamp the raw material plate, forming the initial shape of the speaker grille. Then the hydraulic cylinder is driven to reset the upper stamping die.

[0020] The servo motor drives the rotating seat to rotate 120 degrees, and the forming mesh cover moves to the unloading position with the lower punching die. The ejector rod contacts the abutment seat and is pushed upward to slide. The compression spring compresses the rod, and the rod lifts the mesh cover to obtain the finished product.

[0021] After the finished product is removed, the drive rotating seat continues to rotate, causing the ejector rod to disengage from the abutment seat. The compression spring drives the ejector rod to reset, the seat body is retracted into the receiving groove, and the drive rotating seat continues to rotate. The three lower stamping die seats cycle through the workstations, repeating the above steps to achieve continuous production.

[0022] This invention discloses a speaker grille forming device and method. In use, etched stainless steel raw material plates are first stacked inside a storage cylinder. At this time, a feeding component confines the raw material plates inside the storage cylinder. Then, a servo motor drives the rotating seat to rotate. When one of the lower stamping die holders rotates to directly below the storage cylinder, the feeding component releases the confinement of the raw material plates, and the bottommost raw material plate of the storage cylinder falls into the lower stamping die holder under gravity, completing the loading. After loading is completed, the servo motor continues to drive the rotating seat to rotate, causing the lower stamping die holder loaded with the raw material plate to rotate to the stamping position. Simultaneously, the other empty lower stamping die holder rotates to the loading position, preparing for the next loading. When the raw material plate reaches the stamping position, a hydraulic cylinder drives the upper stamping die holder to move downwards, closely engaging with the lower stamping die holder to stamp the raw material plate. The process involves pressing to form the initial shape of the speaker grille. After pressing, the hydraulic cylinder drives the upper stamping die to reset, and the servo motor drives the rotating seat to rotate 120 degrees again, moving the formed grille along with the lower stamping die to the unloading position. Meanwhile, the lower stamping die, which was previously loaded at the loading position, simultaneously enters the stamping position, awaiting the next stamping operation. When the lower stamping die reaches the unloading position, the ejector component lifts the formed speaker grille from the lower stamping die, separating it from the lower stamping die for easy removal by the operator. Finally, the servo motor drives the rotating seat and the lower stamping die to rotate again, starting a new cycle of loading, stamping, and unloading. Throughout the process, the three lower stamping dies simultaneously perform different processes at three different positions, with seamless connection between loading, stamping, and unloading, eliminating the need for machine downtime and significantly improving the forming efficiency of the speaker grille.

Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0033] First embodiment:

[0034] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the speaker grille forming equipment. Figure 2 This is a schematic diagram of the installation structure of the storage cylinder. Figure 3 This is a structural diagram of the material cutting component. Figure 4 This is a schematic diagram of the mounting structure of a servo motor.

[0035] This invention provides a speaker grille forming device and forming method, including a worktable 101, a mounting frame 102, and a processing component 103. The processing component 103 includes a rotating seat 104, a lower stamping die seat 105, an upper stamping die seat 106, a hydraulic cylinder 107, a storage cylinder 108, a feeding component 109, and a ejector component 110. The feeding component 109 includes a drive seat 111, a connecting rod 112, a limiting seat 113, and an elastic component 114. The elastic component 114 includes a moving frame 115, a drive rod 116, and a reset component. The spring 117, the movable frame 115 also includes a first ball bearing 118, the storage cylinder 108 has an observation groove 119, the rotating seat 104 drives the three lower stamping die seats 105 to move, so that the lower stamping die seats 105 can move to the loading position, the stamping position and the unloading position. The lower stamping die seats 105 in the three positions perform loading, stamping and unloading operations simultaneously. It can be understood that the above solution can be used to improve the processing efficiency of the speaker grille, and can also be used to position the rotating seat 104.

[0036] In this specific embodiment, the rotating seat 104 is rotatably connected to the worktable 101 and is disposed on the worktable 101. The lower stamping die holder 105 is fixedly connected to the rotating seat 104 and is disposed on the rotating seat 104. The hydraulic cylinder 107 is connected to the mounting bracket 102 and is located on the side of the mounting bracket 102 near the rotating seat 104. The upper stamping die holder 106 is disposed on the hydraulic cylinder 107 and connected to the output end of the hydraulic cylinder 107. The storage cylinder 108 is fixedly connected to the mounting bracket 102. The unloading component 109 is disposed on the storage cylinder 108. The top material component 110 is disposed on the worktable 101; three lower stamping die holders 105 are disposed evenly on the rotating seat 104; a servo motor 120 is installed in the worktable 101, and the output end of the servo motor 120 is connected to the rotating seat 104; the storage cylinder 108 is located at the loading position; the hydraulic cylinder 107 and the upper stamping die holder 106 are located at the stamping position; and the top material component 110 is located at the unloading position. The rotating seat 104 is driven to rotate by the servo motor 120, thereby realizing the cyclic switching of the three lower stamping die holders 105 between the three positions.

[0037] In use, etched stainless steel raw material plates are first stacked inside the storage cylinder 108. At this time, the unloading component 109 restricts the raw material plates inside the storage cylinder 108. Then, the servo motor 120 drives the rotating seat 104 to rotate. When one of the lower stamping die seats 105 rotates to be directly below the storage cylinder 108, the unloading component 109 releases the restriction on the raw material plates, and the bottommost raw material plate of the storage cylinder 108 falls into the lower stamping die seat under the action of gravity. Within 105, the loading is completed; after loading is completed, the servo motor 120 continues to drive the rotating seat 104 to rotate, causing the lower stamping die 105 loaded with the raw material plate to rotate to the stamping position. At the same time, another empty lower stamping die 105 rotates to the loading position, preparing for the next loading; when the raw material plate reaches the stamping position, the hydraulic cylinder 107 drives the upper stamping die 106 to move downward, closely cooperating with the lower stamping die 105 to stamp and form the raw material plate. The initial shape of the speaker grille; after stamping, the hydraulic cylinder 107 drives the upper stamping die 106 to reset, and the servo motor 120 drives the rotating seat 104 to rotate 120 degrees again, moving the formed grille along with the lower stamping die 105 to the unloading position. Meanwhile, the lower stamping die 105, which was previously loaded at the loading position, simultaneously enters the stamping position, awaiting the next stamping operation. When the lower stamping die 105 reaches the unloading position, the ejector component 110 lifts the grille... The formed speaker grille on the lower stamping die 105 is lifted up, separating it from the lower stamping die 105, making it easy for the operator to remove the finished product. Finally, the servo motor 120 drives the rotating seat 104 and the lower stamping die 105 to rotate again, starting a new cycle of loading, stamping, and unloading. Throughout the process, the three lower stamping dies 105 simultaneously perform different processes in three positions, with seamless connection between loading, stamping, and unloading, eliminating the need for machine downtime and significantly improving the forming efficiency of the speaker grille.

[0038] The drive seat 111 is fixedly connected to the rotating seat 104 and located on one side of the rotating seat 104; the elastic member 114 is slidably connected to the storage cylinder 108 and is disposed on the storage cylinder 108; the limiting seat 113 is slidably connected to the storage cylinder 108; the two ends of the connecting rod 112 are respectively rotatably connected to the elastic member 114 and the limiting seat 113; two limiting seats 113 and two connecting rods 112 are provided, and the limiting seats 113 limit the raw material plate inside the storage cylinder 108; the elastic member 114 is elastic; three drive seats 111 are provided and are respectively disposed at three lower stamping die seats 105; when the rotating seat 104 rotates, it synchronously drives the drive seat 111 to rotate; when one of the lower stamping die seats 105 rotates to the storage cylinder 108... After the material is moved below 08, the corresponding drive seat 111 rotates to the elastic member 114. At this time, the drive seat 111 drives the elastic member 114 to move, the elastic member 114 drives the connecting rod 112 to move, and the connecting rod 112 drives the limiting seat 113 to move, thereby causing the two limiting seats 113 to move away from each other. At this time, the raw material plate inside the storage cylinder 108 loses the limitation of the limiting seat 113, thereby allowing the bottom raw material plate to fall into the lower stamping die seat 105. When the lower stamping die seat 105 moves away from the bottom of the storage cylinder 108, the corresponding drive seat 111 moves away from the elastic member 114. At this time, the elastic member 114 resets under the elastic action, thereby driving the connecting rod 112 and the limiting seat 113 to reset, thereby re-limiting the raw material plate inside the storage cylinder 108.

[0039] Secondly, the movable frame 115 is slidably connected to the storage cylinder 108 and is disposed on the storage cylinder 108; the drive rod 116 is fixedly connected to the movable frame 115 and is located on one side of the movable frame 115; the two ends of the return spring 117 are respectively connected to the storage cylinder 108 and the movable frame 115, and the return spring 117 is located inside the storage cylinder 108; the return spring 117 provides elasticity to the movable frame 115, and when the drive seat 111 rotates to contact the drive rod 116 and pushes the drive rod 115... When the lever 116 is moved, the moving frame 115 moves synchronously. The sliding of the moving frame 115 is transmitted to the limiting seat 113 through the connecting rod 112, causing the two limiting seats 113 to move away from each other and release the limiting of the raw material plate. When the drive seat 111 disengages from the drive lever 116, the return spring 117 releases the accumulated elastic potential energy, thereby resetting the moving frame 115, the connecting rod 112 and the limiting seat 113, and re-locking the raw material plate in the storage cylinder 108 to prevent it from falling during the non-feeding stage.

[0040] Meanwhile, the first ball bearing 118 is rotatably connected to the drive rod 116 and is located at one end of the drive rod 116; the ball bearing reduces the friction between the drive rod 116 and the drive seat 111.

[0041] In addition, the observation slot 119 is provided on the storage cylinder 108 and extends through the storage cylinder 108; the observation slot 119 allows operators to observe the remaining quantity of the internal raw material plate at any time, so as to replenish the raw material in a timely manner, avoid equipment shutdown due to insufficient raw material, and ensure the continuity of the processing process; the top of the storage cylinder 108 is open, and when replenishing raw material, the raw material is replenished from the top of the storage cylinder 108.

[0042] Second embodiment:

[0043] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 This is a structural schematic diagram of the positioning component in the second embodiment. Figure 6 This is a schematic diagram of the installation structure of the abutment seat in the second embodiment. The processing component 103 in this embodiment also includes a positioning component 209, which includes a cylinder 210 and a positioning seat 211. The ejector component 110 includes an ejector rod 201, a compression spring 202 and an abutment seat 203. The ejector rod 201 includes a seat body 204, a rod body 205, a lifting plate 206 and a second ball bearing 207.

[0044] In this specific embodiment, the ejector rod 201 is slidably connected to the lower stamping die base 105 and is disposed on the lower stamping die base 105; the two ends of the compression spring 202 are respectively connected to the ejector rod 201 and the lower stamping die base 105; the abutment seat 203 is fixedly connected to the worktable 101 and is located on the side of the worktable 101 near the rotating seat 104; three ejector rods 201 and three compression springs 202 are provided and are respectively disposed on three lower stamping die bases 105, and the abutment seat 203 is located in the unloading position. When the lower stamping die base 105 carrying the formed speaker grille moves with the rotating seat 104... When the ejector rod 201 moves to the unloading position, it will contact the abutment seat 203. As the rotating seat 104 continues to rotate, the lower stamping die seat 105 continues to move. At this time, the abutment seat 203 generates an upward pushing force on the ejector rod 201, causing the ejector rod 201 to slide upward along the lower stamping die seat 105, thereby ejecting the workpiece formed in the lower stamping die seat 105. When the rotating seat 104 rotates again, the abutment seat 203 separates from the ejector rod 201, and the ejector rod 201 resets under the elastic action of the compression spring 202, thereby preventing the ejector rod 201 from affecting subsequent loading and stamping operations.

[0045] The rod 205 is slidably connected to the lower stamping die seat 105; the seat 204 is fixedly connected to the rod 205 and located at one end of the rod 205; the lifting plate 206 is fixedly connected to the rod 205 and connected to the compression spring 202, and is sleeved on the compression spring 202; the second ball bearing 207 is rotatably connected to the rod 205 and located on the side of the rod 205 away from the seat 204; the elasticity of the compression spring 202 drives the lifting plate 206 to descend, thereby driving the rod 205 and the seat 204 to descend, thus achieving the purpose of resetting the top rod 201; at the same time, the second ball bearing 207 reduces the friction between the rod 205 and the abutment seat 203, avoiding component wear.

[0046] Secondly, the lower stamping die holder 105 has a receiving groove 208, which cooperates with the seat body 204. When the ejector rod 201 is reset under the action of the compression spring 202, the seat body 204 is retracted into the receiving groove 208. The receiving groove 208 accommodates the seat body 204, so that the top surface of the seat body 204 is flush with the upper surface of the lower stamping die holder 105, thus preventing the seat body 204 from protruding from the surface of the lower stamping die holder 105 and affecting subsequent stamping.

[0047] Meanwhile, the positioning component 209 includes a cylinder 210 and a positioning seat 211. The cylinder 210 is connected to the worktable 101 and located inside the worktable 101. The positioning seat 211 is disposed on the cylinder 210 and connected to the output end of the cylinder 210. The rotating seat 104 has a positioning groove 212, which is disposed on the side of the rotating seat 104 near the positioning seat 211, and the positioning groove 212 cooperates with the positioning seat 211. When the rotating seat 104 is in... Driven by the servo motor 120, the lower stamping die 105 rotates to the designated position. When the lower stamping die 105 precisely corresponds to the loading position, stamping position, or unloading position, the cylinder 210 drives the positioning seat 211 to extend upward, so that it engages with the positioning groove 212 on the rotating seat 104. This positions the rotating seat 104, effectively preventing it from shifting slightly due to external forces during subsequent loading, stamping, or unloading processes, and ensuring that each process can be performed in the accurate position.

[0048] When using the speaker grille forming equipment of the present invention, the operator stacks the etched stainless steel raw material plate into the storage cylinder 108 through the opening at the top of the storage cylinder 108. At this time, the two limiting seats 113 in the feeding component 109 are in a close proximity to each other, restricting the raw material plate inside the storage cylinder 108. After starting the equipment, the servo motor 120 drives the rotating seat 104 to start rotating, and the three lower stamping die seats 105 rotate synchronously with the rotating seat 104. When one of the lower stamping die seats 105 rotates to the feeding position directly below the storage cylinder 108, the corresponding drive seat 111 rotates to the drive rod 116 of the elastic component 114. The drive seat 111 pushes the drive rod 116, causing the moving frame 115 to slide. The sliding of the moving frame 115 is achieved through... The connecting rod 112 drives the two limiting seats 113 to move away from each other, releasing the restriction on the raw material plate. The bottom raw material plate of the storage cylinder 108 falls onto the lower stamping die base 105 under the action of gravity, completing the loading. After loading is completed, the servo motor 120 continues to drive the rotating seat 104 to rotate, the driving seat 111 disengages from the driving rod 116, the return spring 117 releases elastic potential energy, driving the moving frame 115, connecting rod 112 and limiting seat 113 to reset. The limiting seat 113 re-limits the remaining raw material plates. At the same time, the lower stamping die base 105 carrying the raw material plate rotates to the stamping position, and the other empty lower stamping die base 105 rotates to the loading position to prepare for the next loading. When the rotating seat 104 drives the lower stamping die base 105 to the stamping position, In the positioning component 209, the cylinder 210 drives the positioning seat 211 to extend upward and engage with the positioning groove 212 on the rotating seat 104, positioning the rotating seat 104. Then, the hydraulic cylinder 107 drives the upper stamping die 106 to move downward, tightly engaging with the lower stamping die 105 to stamp the raw material plate, forming the initial shape of the speaker grille. After stamping, the hydraulic cylinder 107 drives the upper stamping die 106 to reset, and the cylinder 210 drives the positioning seat 211 to retract, releasing the positioning of the rotating seat 104. The servo motor 120 drives the rotating seat 104 to rotate 120 degrees again. The formed grille is then moved to the unloading position by the lower stamping die 105. Simultaneously, the lower stamping die 105, which had completed loading in the previous process, enters the stamping position. 209 repositions the rotating seat 104, awaiting stamping; when the lower stamping die 105 reaches the unloading position, the ejector rod 201 contacts the abutment seat 203. As the rotating seat 104 continues to rotate, the abutment seat 203 pushes the ejector rod 201 upward, the compression spring 202 is compressed, and the rod 205 lifts the formed mesh cover, separating it from the lower stamping die 105. The operator can easily remove the finished product. After the finished product is removed, the rotating seat 104 continues to rotate, the ejector rod 201 disengages from the abutment seat 203, the compression spring 202 releases its elastic potential energy, driving the lifting plate 206, the rod 205 and the seat 204 to descend and reset. The seat 204 is stored in the receiving groove 208 of the lower stamping die 105, with its top surface flush with the upper surface of the lower stamping die 105.Subsequently, the rotating seat 104 continues to rotate, and the three lower stamping die seats 105, under the precise positioning of the positioning component 209, cyclically switch between the loading position, stamping position, and unloading position, simultaneously performing loading, stamping, and unloading operations. The entire process is seamlessly connected, significantly improving the forming efficiency of the speaker grille.

[0049] On the other hand, please see Figure 7 , Figure 7 This is a flowchart of the speaker grille forming method of the present invention.

[0050] This invention also includes a method for forming a speaker grille, using the aforementioned speaker grille forming equipment, comprising the following steps:

[0051] S1: Stack the etched stainless steel raw material plates in the storage cylinder, and control the two limit seats of the feeding component to move closer to each other to limit the raw material plates and prevent them from falling.

[0052] S2: Control the servo motor to drive the rotating seat to rotate, which drives the three lower stamping die seats to rotate synchronously. When one of the lower stamping die seats reaches the loading position directly below the storage cylinder, control the corresponding drive seat to push the elastic component to move, so that the connecting rod drives the two limit seats to move away from each other, thereby releasing the limit on the raw material plate, allowing the bottom raw material plate to fall into the lower stamping die seat, and completing the loading.

[0053] S3: After the material is loaded, control the lower stamping die holder carrying the raw material plate to rotate to the stamping position, and control another empty lower stamping die holder to move to the loading position. Drive the cylinder of the positioning component to drive the positioning seat to extend and engage with the positioning groove of the rotating seat to achieve positioning.

[0054] S4: After positioning is completed, the hydraulic cylinder is controlled to drive the upper stamping die to move downward, cooperate with the lower stamping die to stamp the raw material plate, forming the initial shape of the speaker grille. Then the hydraulic cylinder is driven to reset the upper stamping die.

[0055] S5: Control the servo motor to drive the rotating seat to rotate 120 degrees, control the forming mesh cover to move to the unloading position with the lower punching die, the ejector rod contacts the abutment seat and is pushed upward to slide, compressed by the compression spring, the rod lifts the mesh cover to obtain the finished product;

[0056] S6: After the finished product is removed, drive the rotating seat to continue rotating, causing the ejector rod to disengage from the abutment seat. The compression spring drives the ejector rod to reset, the seat body is put into the receiving groove, and the rotating seat continues to rotate. The three lower stamping die seats cycle through the workstations, repeating the above steps to achieve continuous production.

[0057] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
