Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a flange stamping device for automobile mufflers. Background Technology

[0002] The connecting flange for automotive mufflers is one of the key components of the automotive muffler system. It is used to connect the tail end of the exhaust pipe to the muffler to reduce the noise generated when the car exhaust is emitted. During the processing of automotive muffler connecting flanges, the blank needs to be punched and perforated to form holes on the flange so that the flange can be connected later.

[0003] However, existing automotive muffler flange stamping devices have limitations when punching individual blanks after stamping. Due to the small size of the blanks, operators need to use clamps to pick up and place them on the stamping platform. Furthermore, the clamps are limited in length, requiring operators to be close to the stamping structure, making the process inconvenient and unsafe. Additionally, after stamping, waste material from the central holes tends to accumulate in the waste chamber at the bottom of the punched holes. If not promptly removed, this can clog the holes and negatively impact subsequent flange stamping. Utility Model Content

[0004] The purpose of this utility model is to provide a flange stamping device for automobile mufflers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange stamping device for an automotive muffler, comprising a chassis, a connecting horizontal plate fixedly connected to the top of the chassis, a stamping mechanism provided in the middle of the connecting horizontal plate, a feeding belt installed at one end of the connecting horizontal plate, a first side block provided on one side of the feeding belt, a first push block provided in the middle of the first side block, a discharge belt installed at the other end of the connecting horizontal plate, a second side block provided on one side of the discharge belt, a second push block provided in the middle of the second side block, a stamping die hole opened in the middle of the top of the connecting horizontal plate, a flange placed at the top of the stamping die hole, a waste chamber opened inside the chassis, actuating discs provided on both inner walls of the waste chamber, a rotating rod passing through the middle of the actuating disc, and a waste belt installed at the bottom of the waste chamber.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, the flange stamping device for automotive mufflers in this embodiment includes a chassis 8. A connecting horizontal plate 3 is fixedly connected to the top of the chassis 8. A stamping mechanism 1 is provided in the middle of the connecting horizontal plate 3. A feeding belt 5 is installed at one end of the connecting horizontal plate 3. A first side block 6 is provided on one side of the feeding belt 5. A first push block 17 is provided in the middle of the first side block 6. A discharge belt 9 is installed at the other end of the connecting horizontal plate 3. A second side block 10 is provided on one side of the discharge belt 9. A second push block 11 is provided in the middle of the second side block 10. A stamping die hole 2 is opened in the middle of the top of the connecting horizontal plate 3. A flange 14 is placed on the top of the stamping die hole 2. A waste chamber 16 is opened inside the chassis 8. A toggle plate 15 is provided on both sides of the inner wall of the waste chamber 16. A rotating rod 18 passes through the middle of the toggle plate 15. A waste belt 4 is installed at the bottom of the waste chamber 16.

[0024] Specifically, the connecting plate 3 allows the flange 14 blank on the feeding belt 5 to be pushed along a defined path onto the stamping die hole 2 of the stamping mechanism 1, enabling the feeding belt 5 and the discharge belt 9 to connect. The feeding belt 5, discharge belt 9, and scrap belt 4 are all conveyor belts, each driven by an independent drive mechanism. The conveying direction of the feeding belt 5 is the same as that of the scrap belt 4, while the conveying direction of the discharge belt 9 is opposite to that of the feeding belt 5. This ensures that the flange 14 blank can be smoothly placed onto and removed from the stamping mechanism 1. The flange 14 is removed from the mechanism 1, making it easier for the operator to operate and allowing the operator to move away from the stamping mechanism 1, thus making the loading and unloading of the flange 14 safer. The first side block 6 and the second side block 10 are symmetrically arranged on both sides of the stamping mechanism 1, allowing the flange 14 blank to slide smoothly along the straight line of the connecting horizontal plate 3. The surface of the actuating plate 15 is rough, which allows it to quickly push the stamping waste down through friction after it comes into contact with the stamping waste, so that it falls onto the waste belt 4 and is discharged out of the device with the waste belt 4, thereby accelerating the speed at which the waste is discharged from the device.

[0025] Furthermore, a first electric cylinder 7 is fixedly installed on one side wall of the first side block 6. The output end of the first electric cylinder 7 is fixedly connected to the first push block 17. The first push block 17 is slidably connected to the connecting horizontal plate 3 through the first electric cylinder 7. The first push block 17 can be pushed by the first electric cylinder 7 to a position close to the discharge belt 9, which is conducive to the flange 14 after stamping sliding to the top of the discharge belt 9.

[0026] Furthermore, a second electric cylinder 12 is fixedly installed on one side wall of the second side block 10. The output end of the second electric cylinder 12 is fixedly connected to the second push block 11. The second push block 11 is slidably connected to the connecting horizontal plate 3 through the second electric cylinder 12. The function of the second push block 11 is to cooperate with the first push block 17 to clamp the flange 14 on the connecting horizontal plate 3 when the flange 14 is stamped, thereby improving the stability of the flange 14 blank during stamping.

[0027] Furthermore, a groove 13 is provided on one side wall of the first push block 17 and the second push block 11. The side wall of the flange 14 fits into the groove 13. The function of the groove 13 is to enable the first push block 17 and the second push block 11 to better clamp the flange 14 for stamping, thereby improving the stamping quality of the flange 14.

[0028] Furthermore, a transmission chain 19 is provided at one end of the rotating rod 18. The transmission chain 19 is connected to the output end of the drive motor on the waste belt 4 through a fixed sprocket. The transmission chain 19 consists of two sprockets and a chain. One sprocket is fixed at one end of the rotating rod 18, while the other sprocket is fixed at the output end of the drive mechanism of the waste belt 4, so that the rotating rod 18 can be driven to rotate, thereby facilitating the rotation of the rotating rod 18.

[0029] Furthermore, the rotating rod 18 is rotatably connected to the waste chamber 16, and the actuating disk 15 is rotatably connected to the waste chamber 16 through the rotating rod 18. The actuating disk 15 can be driven by the rotating rod 18 to rotate in the waste chamber 16, thereby enabling the actuating disk 15 to actuate the waste blocks falling in the waste chamber 16, which facilitates the stamping waste to slide quickly onto the waste belt 4.

[0030] Furthermore, the interior of the waste chamber 16 is connected to the interior of the stamping die hole 2, so that the stamping waste can be pushed into the waste chamber 16 by the stamping mechanism 1, and the stamping waste can fall smoothly onto the waste belt 4 and be discharged out of the device.

[0031] The method of use in this embodiment is as follows: When using this automotive muffler flange 14 stamping device, the device needs to be connected to an external power supply first. Then, the flange 14 blank to be stamped is placed at the inlet of the feeding belt 5. At this time, the flange 14 will be moved to one side of the first push block 17 under the transmission of the feeding belt 5. Then, the first electric cylinder 7 and the second electric cylinder 12 will be started simultaneously and push the first push block 17 to slide along the connecting horizontal plate 3. At this time, the first push block 17 will drive the flange 14 to slide towards the stamping die hole 2 on the connecting horizontal plate 3. At the same time, the second push block 11 will also be pushed to one side of the stamping die hole 2 by the second electric cylinder 12. When the two side walls of the flange 14 are respectively against the side walls of the first push block 17 and the second push block 11, When the groove 13 is fitted, the stamping mechanism 1 will start to stamp the flange 14. Then, the waste material formed after stamping will be pushed into the waste material cavity 16 at the bottom by the stamping mechanism 1. As the waste material belt 4 rotates, the rotating rod 18 will also rotate under the drive of the transmission chain 19, so that the agitator 15 will agitate the waste material pushed into the waste material cavity 16, so that the waste material will quickly slide down onto the waste material belt 4 at the bottom of the waste material cavity 16, and then be discharged out of the device with the waste material belt 4. At the same time, the flange 14 that has completed stamping will be clamped and moved onto the discharge belt 9 by the first push block 17 and the second push block 11. Finally, the first push block 17 and the second push block 11 will separate from the flange 14, so that the flange 14 that has completed stamping will slide out of the device with the discharge belt 9.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
