Description

Technical Field

[0001] This utility model relates to the field of automotive muffler flange production technology, specifically to a feeding device for stamping automotive muffler flanges. Background Technology

[0002] Stamping of automotive muffler flanges is a manufacturing process that uses a press and precision molds to apply pressure to sheet metal, causing it to plastically deform or separate, thereby obtaining parts that meet design requirements. During production, the sheet metal is first cut to specifications and placed into a stamping die. The press applies strong pressure, reshaping the sheet metal within the die cavity, or separating it using cutting edges to form the desired contour, thus completing the initial forming of the flange. Stamped flanges have high dimensional accuracy and good surface quality, meeting the connection and sealing performance requirements of automotive mufflers. This process allows for mass production, offering high efficiency and low cost, making it an indispensable and crucial step in automotive parts manufacturing.

[0003] In the material feeding process for stamping automotive muffler flanges, traditional manual feeding has many drawbacks. Workers need to operate manually frequently, and long hours of repetitive work can easily lead to fatigue, resulting in sluggish movements and significantly reducing production efficiency. This makes it difficult to meet the needs of large-scale production. The high intensity of physical labor keeps workers under constant stress, which can easily cause physical injuries. Furthermore, the accuracy of plate positioning and placement during manual operation depends on personal experience. Even slight negligence can lead to stamping deviations, resulting in quality problems such as inconsistent product dimensions and surface defects. This not only increases the scrap rate but also delays production progress due to rework, seriously restricting the company's efficiency and development. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding device for stamping automotive muffler flanges, which has the advantages of automatic and precise feeding, and solves the problems of high intensity and product deviation during stamping caused by manual feeding as mentioned in the background technology.

[0005] To achieve the aforementioned goal of automatic and precise material feeding, this utility model provides the following technical solution: a material feeding device for stamping automotive muffler flanges, comprising a stamping table, with supporting sliding rods fixedly connected to both sides of the top of the stamping table, a stamping die slidably connected to the outer wall of the supporting sliding rods, a feeding plate fixedly connected to the top of the stamping table, a metal plate placed in the inner cavity of the feeding plate, a flange hole extending through one side of the metal plate, a connecting block fixedly connected to the outer wall of the stamping die away from the supporting sliding rods, and a connecting block fixedly connected to the top of the stamping table near the feeding plate. The mounting block has a screw fixedly connected to its bottom, which passes through the mounting block and slides through the stamping table. An L-shaped moving rod passes through and slides through the inner cavity of the mounting block. A rack passes through and is fixedly connected to one side of the L-shaped moving rod.

[0007] As a further embodiment of this utility model: a limiting groove is provided through the middle of one side of the feeding plate, and an extrusion plate is slidably connected to the inner cavity of the L-shaped moving rod, and the extrusion plate abuts against the feeding plate.

[0008] As a further improvement of this utility model: springs are fixedly connected to one side of the inner cavity of the limiting groove, and the side of the spring away from the limiting groove is fixedly connected to the extrusion plate.

[0009] As a further improvement of this utility model, a sliding groove is provided on the top of the stamping table near the mounting block.

[0010] As a further improvement of this utility model: the side of the L-shaped moving rod away from the contact block is fixedly connected to the second pressing plate, and the bottom of the second pressing plate slides in the groove.

[0011] As a further improvement of this utility model, the side of the second extrusion plate away from the L-shaped moving rod abuts against the side of the first extrusion plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, during the stamping operation, after the stamping die presses down on the metal sheet to complete the stamping, it resets, causing the connecting block and screw to rise. The screw and screw groove work together to drive the gear and rotating ring to rotate.

[0015] 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.

[0016] Please see Figures 1-7In this embodiment of the present invention, a feeding device for stamping an automotive muffler flange includes a stamping table 1. Supporting sliding rods 2 are fixedly connected to both 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. A feeding plate 4 is fixedly connected to the top of the stamping table 1. A metal plate 5 is placed in the inner cavity of the feeding plate 4. A flange hole 6 is opened through one side of the metal plate 5. A connecting block 7 is fixedly connected to the outer wall of the stamping die 3 away from the supporting sliding rods 2. An mounting block 9 is fixedly connected to the top of the stamping table 1 near the feeding plate 4. A screw 8 is fixedly connected to the bottom of the connecting block 7, and the screw 8 passes through the mounting block 9 and is slidably connected to the stamping table 1. An L-shaped moving rod 10 is slidably connected through the inner cavity of the mounting block 9. A rack 11 is fixedly connected through one side of the L-shaped moving rod 10. A gear 12 is provided in the inner cavity of the mounting block 9. Rotating rings 13 are fixedly connected to both the upper and lower sides of 2, and rotating rings 13 are rotatably connected to mounting blocks 9. Gear 12 has a threaded groove 14 through its middle, and screw 8 is threadedly connected to screw groove 14. One end of L-shaped moving rod 10 is fixedly provided with abutting block 15, and abutting block 15 abuts against each other in flange hole 6. During stamping operation, after stamping die 3 presses down on metal sheet 5 to complete stamping, it begins to reset, and at the same time drives connecting block 7 and screw 8 to rise together. During the reset process, screw 8 cooperates with screw groove 14 to drive gear 12 and rotating ring 13 to rotate. Gear 12 rotates and meshes with rack 11, so that L-shaped moving rod 10 slides down along limit rod 19. The sliding of L-shaped moving rod 10 drives abutting block 15 on one side to move and abut against one side of the inner cavity of flange hole 6, pushing metal sheet 5 to move and accurately transferring the unstamped part to below stamping die 3. A rotating rod 16 is rotatably connected to the side of the L-shaped moving rod 10 near the contact block 15, and the rotating rod 16 is fixedly connected to the contact block 15. An arc-shaped groove 17 is formed on the side of the L-shaped moving rod 10 near the rotating rod 16. An arc-shaped spring 18 is fixedly connected to one side of the inner cavity of the arc-shaped groove 17. A limit rod 19 is slidably connected to the side of the inner cavity of the arc-shaped groove 17 away from the arc-shaped spring 18, and the limit rod 19 is fixedly connected to the arc-shaped spring 18. The side of the limit rod 19 away from the arc-shaped groove 17 is fixedly connected to the contact block 15. The stamping die 3 moves down again to stamp the feeding plate 4. At the same time as the stamping die 3 moves down, it drives the connecting block 7 and the screw 8 to move down synchronously. The screw 8 drives the gear 12 and the rotating ring 13 to rotate in opposite directions through the screw groove 14. The wheel 12 rotates in the opposite direction, causing the L-shaped moving rod 10 and the contact block 15 to move in the opposite direction. When the contact block 15 contacts the flange hole 6, the contact block 15 rotates around the rotating rod 16, and at the same time, it causes the limiting rod 19 to rotate in the arc groove 17, compressing the arc spring 18, so that the contact block 15 disengages from the flange hole 6, and then moves to the next flange hole 6. With the help of the elastic force of the arc spring 18, the limiting rod 19 and the contact block 15 are reset and contact the flange hole 6, realizing the automatic forward movement of the feeding plate 4, ensuring that the unpressed area is accurately aligned with the stamping die 3. It should be noted that the bottom of the stamping die 3 integrates a dual-function module for punching and forming, and the top of the stamping die 3 is equipped with a hydraulic structure, which is existing technology. A limiting groove 20 is formed through the middle of one side of the feeding plate 4. An extrusion plate 21 is slidably connected to the inner cavity of the L-shaped moving rod 10, and the extrusion plate 21 abuts against the feeding plate 4. A spring 22 is fixedly connected to one side of the inner cavity of the limiting groove 20, and the side of the spring 22 away from the limiting groove 20 is fixedly connected to the extrusion plate 21. A sliding groove 24 is formed on the top of the stamping table 1 near the mounting block 9. An extrusion plate 23 is fixedly connected to the side of the L-shaped moving rod 10 away from the contact block 15, and the bottom of the extrusion plate 23 slides in the sliding groove 24. The extrusion plate 23 is away from the L-shaped moving rod. One side of 10 abuts against one side of extrusion plate 21. When the stamping die 3 is pressed down, the L-shaped moving rod 10 resets and moves, causing extrusion plate 23 to slide in the slide groove 24. Extrusion plate 23 abuts against extrusion plate 21 with an angle, causing extrusion plate 21 to slide into the limiting groove 20, thereby extruding the discharge plate 4 and preventing it from moving during stamping. When extrusion plate 23 separates from extrusion plate 21, extrusion plate 21 resets under the elastic force of spring 22, releasing the extrusion on discharge plate 4, so that the contact block 15 abuts against the flange hole 6 and drives discharge plate 4 to move.

[0017] The working principle of this utility model is as follows: During the stamping operation, after the stamping die 3 presses down on the metal sheet 5 to complete the stamping, it begins to reset. At the same time, it drives the connecting block 7 and the screw 8 to rise together. During the reset process, the screw 8 cooperates with the screw groove 14 to drive the gear 12 and the rotating ring 13 to rotate. The gear 12 rotates and meshes with the rack 11, so that the L-shaped moving rod 10 slides down along the limiting rod 19. The sliding of the L-shaped moving rod 10 drives the abutment block 15 on one side to move and abut against the inner cavity of the flange hole 6, pushing the metal sheet 5 to move and accurately transferring the unstamped part to the bottom of the stamping die 3. Subsequently, the stamping die 3 moves down again to stamp the feeding plate 4. As the stamping die 3 moves down, it drives the connecting block 7 and the screw 8 to move down synchronously. The screw 8 drives the gear 12 and the rotating ring 13 to rotate in opposite directions through the screw groove 14. The gear 12 rotates in opposite directions, driving the L-shaped moving rod 10 and the contact block 15 to move in opposite directions. When the contact block 15 contacts the flange hole 6, the contact block 15 rotates around the rotating rod 16, and at the same time drives the limiting rod 19 to rotate in the arc groove 17, compressing the arc spring 18, so that the contact block 15 is separated from the flange hole 6. Then it moves to the next flange hole 6. With the help of the elastic force of the arc spring 18, the limiting rod 19 and the contact block 15 are reset and contact the flange hole 6, realizing the automatic forward movement of the feeding plate 4, ensuring that the unstamped area is accurately aligned with the stamping die 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
