Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive muffler flange processing technology, specifically to a high-continuity automotive muffler flange stamping device. Background Technology
[0002] The automotive muffler flange stamping device is a specialized piece of equipment used to process automotive muffler flanges. It uses a press or other stamping equipment and a die to apply pressure to a metal sheet, causing plastic deformation or separation, thereby forming a flange part with a specific shape and size. This device generally includes a die system (upper and lower dies), a positioning mechanism, and a pressure transmission structure, ensuring accurate positioning and uniform stress on the sheet metal during stamping, thus improving the processing accuracy and production efficiency of the flanges. In actual production, to further improve efficiency and reduce costs, this stamping device can be extended to continuous stamping processes. Continuous stamping refers to the continuous stamping of sheet metal on the same stamping equipment using multi-station dies, allowing the sheet metal to gradually complete multiple processes such as punching, blanking, and forming during feeding. Compared to single-process stamping, it has advantages such as high production efficiency, good product consistency, and low labor costs, and is particularly suitable for processing high-volume parts such as automotive muffler flanges.
[0003] In the manufacturing process of automotive mufflers, the flange, as a crucial connecting component, has a significant impact on the efficiency and quality of its stamping process. Currently, while existing automotive muffler flange stamping equipment possesses a certain degree of continuous stamping capability, there are obvious defects in the unloading process after stamping. Most existing equipment adopts a uniform unloading method, where the stamped flange and the generated waste material fall together without effective differentiation and separation. This unloading method makes the subsequent manual or mechanical separation of the flange and waste material extremely cumbersome, not only consuming a large amount of manpower and time costs, but also making it difficult to achieve fast and accurate unloading of the flange due to the mixing of waste material and flange material. This severely restricts the unloading speed of the flange, thereby reducing the continuity and efficiency of the entire production process and failing to meet the ever-increasing demand for high-efficiency production in the automotive manufacturing industry. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a continuous automotive muffler flange stamping device with the advantages of automatic separation of waste material from flanges and rapid material unloading. This solves the problems of the prior art, which involves mixing and unloading waste material with flanges after stamping, resulting in cumbersome separation operations, low material unloading efficiency, and poor production continuity.
[0005] To achieve the aforementioned goals of automatic separation of waste materials and flanges, and rapid material unloading, this utility model provides the following technical solution: A continuous automotive muffler flange stamping device, comprising a stamping table, with supporting sliding rods fixedly connected to the left and right sides of the top side of the stamping table, and a stamping die slidably connected to the outer wall of the supporting sliding rods. A stamping groove is formed on one side of the top center of the stamping table, and a feeding groove is formed through the lower part of the stamping table at the stamping groove. A feeding box is fixedly connected to the bottom of the stamping table at the through position of the feeding groove, and the feeding box cooperates with the feeding groove. A second stamping groove is formed on the top side of the stamping table away from the stamping groove. A second feeding groove is formed through the lower part of the stamping table at the stamping groove. A second feeding box is fixedly connected to the bottom of the stamping table at the through position of the feeding groove, and the feeding box cooperates with the feeding groove. A screening plate is provided in the inner cavity of the feeding box.
[0006] As a further embodiment of this utility model: sliding grooves are provided on both sides of the inner cavity of the second feeding box, and evenly distributed sliding rods are fixedly connected to the inner cavities of the two sliding grooves. Slide plates are slidably connected to the middle of the inner cavities of the two sliding grooves, and the slide plates slide through the sliding rods. Springs are sleeved on the outer walls of the multiple sliding rods, and one end of the spring is fixedly connected to the inner cavity of the sliding groove. The ends of the springs away from the sliding grooves are fixedly connected to the slide plates. A screening plate is fixedly connected between the two slide plates.
[0007] As a further embodiment of this utility model: a connecting rod is fixedly connected to one side of the stamping die, and the side of the connecting rod away from the stamping die passes through the stamping table and the unloading box and is slidably connected.
[0008] As a further improvement of this utility model: the connecting rod passes through the side of the feeding box two away from the supporting sliding rod and is rotatably connected to a swing rod.
[0009] As a further improvement of this utility model: an abutment block is fixedly connected to the side of the swing rod away from the connecting rod, and the abutment block abuts against the sieve plate.
[0010] As a further improvement of this utility model: the middle part of the swing rod is rotatably connected to a rotating rod, and the two sides of the rotating rod are fixedly connected to the inner cavity of the feeding box 2.
[0011] As a further improvement of this utility model: a U-shaped feeding plate is fixedly connected to the top of the stamping table, and grooves corresponding to the feeding groove one and the stamping groove two are opened on both sides of the top of the U-shaped feeding plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, during equipment operation, the operator places the sheet material to be processed into the U-shaped feeding plate and starts the downward operation of the stamping die. The punching and forming dual-function module integrated at the bottom works in tandem. During the first stamping, the sheet material completes the opening process through the punching die. The waste material falls vertically through the gap between the U-shaped feeding plate and the second stamping groove, and is conveyed to the screening plate through the second feeding groove to achieve the initial separation of waste material. After the punching is completed, the sheet material is pushed to the forming station, and the stamping die presses down again to complete the plastic processing. The formed flange quickly falls into the first feeding box through the first stamping groove and the first feeding groove for centralized collection. The silencer flange after stamping can be quickly removed. The entire process does not require manual intervention to separate waste material from finished product, significantly improving feeding efficiency and ensuring production continuity.
[0014] 2. In this utility model, the downward pressing action of the stamping die drives the swinging rod to swing around the rotating rod as the fulcrum, striking the screening plate. Because the size of the punched waste is different, the striking force of the swinging rod drives the screening plate to slide back and forth in the guide structure composed of the sliding plate and the sliding groove, compressing the spring to store energy. When the stamping die moves upward to reset, the connecting rod drives the swinging rod to release the resistance to the screening plate, and the spring releases its elastic potential energy, causing the screening plate to vibrate at high frequency, realizing the fine screening of waste. Smaller waste falls through the two screen holes of the stamping groove, and larger waste slides down the inclined surface of the screening plate, completing the rapid screening of waste.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 In this embodiment of the present invention, a continuous automotive muffler flange stamping device includes a stamping table 1. Supporting sliding rods 2 are fixedly connected to the left and right sides of the top of the stamping table 1. A stamping die 3 is slidably connected to the outer wall of the supporting sliding rods 2. It should be noted that a stamping mold is provided below the stamping die 3. The bottom of the stamping die 3 integrates a dual-function module for punching and forming. A hydraulic structure is provided on the top of the stamping die 3, which is prior art. A stamping groove 4 is opened on one side of the top center of the stamping table 1. A feeding groove 5 is opened through the lower part of the stamping groove 4 on the stamping table 1. A feeding box 6 is fixedly connected to the bottom of the stamping table 1 at the through position of the feeding groove 5, and the feeding box 6 cooperates with the feeding groove 5. A second stamping groove 8 is opened on the top side of the stamping table 1 away from the stamping groove 4. The lower part of the stamping table 1 is provided with a feeding groove 2 9. The bottom of the stamping table 1 is fixedly connected to the feeding box 2 7 at the through position of the feeding groove 2 9. The feeding box 2 7 cooperates with the feeding groove 2 9. The inner cavity of the feeding box 2 7 is provided with a screening plate 18. The stamping die 3 is started to move downward. The bottom of the die integrates a punching and forming dual-function module. During the first stamping, the sheet metal completes the punching process through the punching die. The waste material generated falls vertically through the gap between the U-shaped feeding plate 19 and the stamping groove 2 8. It is then transported to the screening plate 18 through the feeding groove 2 9 for initial separation. After the punching process is completed, the operator pushes the sheet metal forward to the forming station. The stamping die 3 presses down again and uses the forming die to plastically process the sheet metal. The formed flange falls into the feeding box 6 through the channel between the stamping groove 1 4 and the feeding groove 1 5 for centralized collection, realizing the separation of materials after stamping.
[0023] The inner cavity of the feeding box 7 has sliding grooves 14 on both sides. Evenly distributed sliding rods 15 are fixedly connected to the inner cavities of the two sliding grooves 14. Slide plates 16 are slidably connected to the middle of the inner cavities of the two sliding grooves 14, and the slide plates 16 slide through the sliding rods 15. Springs 17 are sleeved on the outer walls of the multiple sliding rods 15, with one end of the spring 17 fixedly connected to the inner cavity of the sliding groove 14. The ends of the springs 17 away from the sliding grooves 14 are fixedly connected to the slide plates 16. A screening plate 18 is fixedly connected between the two slide plates 16. The stamping die 3... A connecting rod 10 is fixedly connected to one side of the stamping die 3. The side of the connecting rod 10 away from the stamping die 3 passes through the stamping table 1 and is slidably connected to the unloading box 7. A swing rod 11 is rotatably connected to the side of the connecting rod 10 that is away from the supporting sliding rod 2. A contact block 13 is fixedly connected to the side of the swing rod 11 that is away from the connecting rod 10, and the contact block 13 abuts against the sieve plate 18. A rotating rod 12 is rotatably connected to the middle of the swing rod 11, and both sides of the rotating rod 12 are fixedly connected to the inner cavity of the unloading box 7. The stamping die 3 The downward pressing action drives the swing rod 11 via the connecting rod 10 to swing around the rotating rod 12 as the fulcrum, periodically striking the screening plate 18. Because the waste produced by punching varies in size, the striking force of the swing rod 11 drives the screening plate 18 to slide back and forth within the guide structure formed by the sliding plate 16 and the sliding groove 14, compressing the spring 17 to store energy. When the stamping die 3 moves upward to reset, the connecting rod 10 drives the swing rod 11 to release its resistance to the screening plate 18, and the spring 17 releases its elastic potential energy, causing the screening plate 18 to vibrate at high frequency, thus realizing the waste... In the material screening process, smaller waste materials fall through the screen holes of the second stamping groove 8, while larger waste materials slide down the inclined surface of the screening plate 18. A U-shaped feeding plate 19 is fixedly connected to the top of the stamping table 1, and slots corresponding to the first feeding groove 5 and the second stamping groove 8 are opened on both sides of the top of the U-shaped feeding plate 19. The U-shaped feeding plate 19 is fixed to the top of the stamping table 1, and the slots on both sides are aligned with the first feeding groove 5 and the second stamping groove 8, respectively, for waste material discharge and passage of stamping dies to achieve continuous stamping operation. The second feeding box 7 and the screening plate 18 are inclined and guide the flow, forming a smooth and efficient waste material discharge channel to ensure smooth and unobstructed material discharge.
[0024] The working principle of this utility model is as follows: When the equipment is running, the operator places the sheet material to be processed in the U-shaped feeding plate 19 and starts the stamping die 3 to move downward. The bottom of the die integrates a dual-function module for punching and forming. During the first stamping, the sheet material completes the opening process through the punching die. The waste material generated falls vertically through the gap between the U-shaped feeding plate 19 and the second stamping groove 8, and is transported to the screening plate 18 for initial separation through the second feeding groove 9. After the punching process is completed, the operator pushes the sheet material forward to the forming station. The stamping die 3 presses down again and uses the forming die to plastically process the sheet material. The formed flange falls into the feeding box 6 for centralized collection through the channel between the first stamping groove 4 and the first feeding groove 5, realizing the separation of materials after stamping. During the stamping process of the forming die, the punching die starts synchronously to achieve continuous and uninterrupted stamping.
[0025] Meanwhile, the downward pressing action of the stamping die 3 will drive the swing rod 11 to swing around the rotating rod 12 as the fulcrum via the connecting rod 10, and periodically strike the screening plate 18. Since the waste generated by punching is of different sizes, the striking force of the swing rod 11 drives the screening plate 18 to slide back and forth in the guide structure composed of the sliding plate 16 and the sliding groove 14. The compressed spring 17 stores energy. When the stamping die 3 moves upward to reset, the connecting rod 10 drives the swing rod 11 to release the resistance to the screening plate 18. The spring 17 releases elastic potential energy, causing the screening plate 18 to vibrate at high frequency, thereby realizing the screening of waste. Smaller waste falls through the screen holes of the stamping groove 2 8, while larger waste slides down the inclined surface of the screening plate 18. With the inclined guide design of the feeding box 2 7 and the screening plate 18, a smooth and efficient waste discharge channel is formed, ensuring that the feeding process is smooth and unobstructed.
