[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to the following: Figures 1 to 7 To achieve the above objectives, this utility model provides the following technical solution:

[0024] A continuous stamping device for aluminum gaskets used in automotive parts includes a base 1, which has a "U"-shaped structure; a double-row belt conveyor 2 is provided on one side of the base 1, wherein the feed end of the double-row belt conveyor 2 extends to the bottom of the base 1; a lower pad 3 is provided at the upper end of the base 1, wherein a stamping table 4 is provided at the upper end of the lower pad 3, and the stamping table 4 is fixedly connected to the lower pad 3; an upper pad 5 is provided above the lower pad 3, wherein the upper pad 5 is movably connected to the lower pad 3; an inner ring forming hole 6 and a blanking hole 7 are provided at the upper end of the stamping table 4, wherein the inner ring forming hole 6 and the blanking hole 7 are arranged side by side; the inner ring forming hole 6 and the blanking hole 7 are arranged side by side; the inner ring forming hole 6 and the blanking hole 7 are arranged side by side; the inner ring forming hole 6 and the blanking hole 7 are arranged side by side; the upper end of the stamping table 4 has an inner ring forming hole 6 and a blanking hole 7, wherein ... The forming hole 6 and the blanking hole 7 are both trumpet-shaped structures that are narrow at the top and wide at the bottom. The base 1 has a discharge hole (not shown in the figure) corresponding to the lower end of the inner ring forming hole 6 and the blanking hole 7. The two long sides of the upper end of the stamping table 4 are symmetrically provided with guide strips 8, and a pressure plate 9 is provided above the guide strips 8. The pressure plate 9 and the stamping table 4 form a material guiding channel 10, and the pressure plate 9 has a through hole 11 corresponding to the inner ring forming hole 6 and the blanking hole 7. The upper pad 5 is provided with a small punch 12 and a large punch 13, respectively. The small punch 12 is adapted to the inner ring forming hole 6, and the large punch 13 is adapted to the blanking hole 7.

[0025] The raw material is placed in the guide channel 10, which consists of a stamping table 4 and a pressure plate 9. The design of the pressure plate 9 ensures that the raw material can be accurately aligned with the inner ring forming hole 6 and the blanking hole 7 on the stamping table 4. The guide strip 8 further guides the placement of the raw material, ensuring the accuracy of the stamping. The upper pad 5 begins to move downward under the action of the drive mechanism, driving the small punch 12 and the large punch 13 into the inner ring forming hole 6 and the blanking hole 7, respectively. The small punch 12 performs preliminary stamping on the aluminum pad in the inner ring forming hole 6 to form the required inner ring shape. The circular scrap generated by stamping falls into the first conveyor through the discharge hole on the base 1. The material is conveyed to the waste recycling box 14 via conveyor belt 202. Then, the material is pushed forward, causing the large punch 13 to fully press the aluminum pad within the discharge hole 7, forming the final aluminum pad product. This finished product then falls directly onto the second conveyor belt 203 through the discharge hole on the base 1 corresponding to the discharge hole 7, and is conveyed to the finished product storage box 15. The flared inner ring forming hole 6 and discharge hole 7 design help guide the movement of the punch while reducing material waste and resistance during the stamping process. The synchronous operation of the double-row belt conveyor line 2 ensures immediate and automatic separation of waste and finished products, improving production efficiency.

[0026] Please refer to the following: Figure 1 , Figure 6 As an embodiment of the present utility model, the double-row belt conveyor line 2 includes a support base 201, wherein a first conveyor belt 202 and a second conveyor belt 203 are respectively provided on both sides of the support base 201; the feeding end of the first conveyor belt 202 is located below the inner ring forming hole 6, wherein a waste recycling box 14 is provided below the discharge end of the first conveyor belt 202; the feeding end of the second conveyor belt 203 is located below the discharge hole 7, wherein a finished product storage box 15 is provided below the discharge end of the second conveyor belt 203.

[0027] In the above-described scheme, after the stamping device is ready, the raw material is gradually brought close to the stamping table 4 and inserted into the guide channel 10; the upper pad 5 begins to move downward under the action of the drive mechanism, driving the small punch 12 and the large punch 13 into the inner ring forming hole 6 and the blanking hole 7 respectively; the small punch 12 performs preliminary stamping on the aluminum pad in the inner ring forming hole 6 to form the required inner ring shape, wherein the circular waste generated by stamping falls into the first conveyor belt 202 through the discharge hole on the base 1, the first conveyor belt 202 continues to run, transporting the waste from the stamping area to its discharge end, below the discharge end, there is a waste recycling box 14, the waste falls from the first conveyor belt 202 and is collected in the waste recycling box 14 for subsequent processing; pushing the raw material Moving forward, the large punch 13 completely punches the aluminum gasket within the blanking hole 7, forming the final finished aluminum gasket. This finished product then falls directly onto the second conveyor belt 203 through the discharge hole on the base 1, corresponding to the blanking hole 7. As the second conveyor belt 203 runs, the finished gasket is transported to its discharge end. Below the discharge end, a finished product storage box 15 is provided. The finished gaskets falling from the second conveyor belt 203 are neatly collected in the finished product storage box 15, awaiting subsequent inspection, packaging, or further processing. The double-row belt conveyor line 2, through precise design and synchronized operation, realizes the input of aluminum gasket raw materials, the output of waste materials, and the collection of finished products, providing efficient and stable material flow support for the entire stamping process. This design not only improves production efficiency but also ensures the continuity and automation of the production process.

[0028] Please refer to the following: Figure 6 , Figure 7 In one embodiment of this utility model, a first drive wheel 204 is provided on the side of the support base 201 near the first conveyor belt 202, and a second drive wheel 205 is provided on the side of the support base 201 near the second conveyor belt 203, and the first drive wheel 204 and the second drive wheel 205 are coaxially arranged; a drive motor 206 is provided on one side of the support base 201, wherein the drive motor 206 is fixedly connected to the side wall of the support base 201 through a motor fixing seat 207; a rotating shaft is fixedly connected to the output end of the drive motor 206, wherein the rotating shaft is connected to the first drive wheel 204 and the second drive wheel 205 respectively.

[0029] In the above-described scheme, the motor is securely mounted on one side of the support base 201 via the motor mounting bracket 207, ensuring stability during operation. The output end of the drive motor 206 is connected to a rotating shaft, a key component of the drive system. When the motor starts, it generates rotational power, which is transmitted to other components via the shaft. On the support base 201, a first drive wheel 204 is located near the first conveyor belt 202, while a second drive wheel 205 is located near the second conveyor belt 203. The first drive wheel 204 and the second drive wheel 205 are coaxial, meaning they share the same axis, thus ensuring synchronous rotation. The rotating shaft passes through the support base 201 and connects to both the first drive wheel 204 and the second drive wheel 205. This connection method ensures that when the motor drives the rotating shaft to rotate... During operation, the first drive wheel 204 and the second drive wheel 205 can rotate simultaneously and synchronously. The surfaces of the first drive wheel 204 and the second drive wheel 205 are designed with transmission surfaces for contacting the conveyor belt. Since the first drive wheel 204 and the second drive wheel 205 are coaxially arranged and driven by the same shaft, they can ensure that the first conveyor belt 202 and the second conveyor belt 203 operate synchronously. This synchronicity is crucial for maintaining the continuity and stability of the stamping process. After stamping, the waste and finished products are transported to the corresponding collection positions via the first conveyor belt 202 and the second conveyor belt 203, respectively. The waste is transported to the waste recycling box 14, while the finished products are transported to the finished product storage box 15. This design not only ensures the continuity and stability of the stamping process but also improves production efficiency and quality.

[0030] Please refer to the following: Figure 6 , Figure 7 As one embodiment of the present invention, a first tensioning wheel 16 is provided on both sides above the first drive wheel 204, wherein the first drive wheel 204 is connected to the inner side of the first conveyor belt 202, and the first tensioning wheel 16 abuts against the outer side of the first conveyor belt 202 respectively; a second tensioning wheel 17 is provided on both sides above the second drive wheel 205, wherein the second drive wheel 205 is connected to the inner side of the second conveyor belt 203, and the second tensioning wheel 17 abuts against the outer side of the second conveyor belt 203 respectively.

[0031] In the above-described scheme, the first tensioner 16 and the second tensioner 17 are mainly used to adjust and maintain the tension of the first conveyor belt 202 and the second conveyor belt 203, ensuring that the first conveyor belt 202 and the second conveyor belt 203 can closely adhere to the first drive wheel 204 and the second drive wheel 205 during transmission, reducing slippage and wear of the first conveyor belt 202 and the second conveyor belt 203, and improving transmission efficiency. The first tensioner 16 and the second tensioner are usually equipped with adjustment mechanisms, allowing the operator to make fine adjustments according to the wear condition and tension requirements of the first conveyor belt 202 and the second conveyor belt 203. By adjusting the position or pressure of the first tensioner 16 and the second tensioner, the tension of the first conveyor belt 202 can be ensured. The belt 202 and the second conveyor belt 203 maintain a stable tension during long-term operation. The first tensioning pulley 16 abuts against the outer edge of the first conveyor belt 202. This contact method ensures that the first tensioning pulley 16 can effectively apply inward pressure to the first conveyor belt 202, thereby maintaining the tension of the first conveyor belt 202. Similarly, the second tensioning pulley 17 also abuts against the outer edge of the second conveyor belt 203. This contact method ensures that the second tensioning pulley 17 can effectively apply inward pressure to the second conveyor belt 203, thereby maintaining the tension of the second conveyor belt 203. This greatly improves transmission efficiency. This design not only improves production efficiency and quality but also extends the service life of the conveyor line.

[0032] Please refer to the following: Figures 1 to 3 As one embodiment of this utility model, guide rods 18 are symmetrically arranged on both sides of the stamping table 4, wherein the lower end of the guide rod 18 is fixedly connected to the lower pad 3; guide sleeves 19 adapted to the guide rods 18 are respectively provided on both sides of the lower end of the upper pad 5, wherein the upper end of the guide sleeve 19 is fixedly connected to the upper pad 5 through the connecting plate 20, and the lower end of the guide sleeve 19 is fixedly connected to the buffer sleeve 21; an avoidance hole 22 is opened at one end of the upper pad 5 near the guide sleeve 19, wherein the guide rod 18 passes through the guide sleeve 19 and extends into the avoidance hole 22.

[0033] In the above-described scheme, the guide rod 18 is symmetrically installed on both sides of the stamping table 4, and its lower end is firmly fixed to the lower pad 3 by welding, bolts or other means. The lower pad 3 provides a stable support base for the guide rod 18. The lower ends of the upper pad 5 are respectively provided with guide sleeves 19 that are adapted to the guide rod 18. The guide sleeves 19 are fixedly connected to the upper pad 5 through the connecting plate 20 to ensure that the guide sleeves 19 can maintain stability and linear movement when moving up and down. The lower end of the guide sleeve 19 is fixedly connected to a buffer sleeve 21, which is usually made of elastic material, such as rubber or spring. 23 steel, etc., is used to absorb and disperse impact force during the stamping process, protecting the guide rod 18 and guide sleeve 19 from damage; the upper pad 5 has a relief hole 22 at one end near the guide sleeve 19, and the guide rod 18 can pass through the guide sleeve 19 and extend into the relief hole 22. This design allows the guide rod 18 to slide freely in the guide sleeve 19, while maintaining the relative position stability between the upper pad 5 and the lower pad 3; the fit between the guide rod 18 and the guide sleeve 19 is usually a sliding fit, that is, the guide rod 18 can slide smoothly in the guide sleeve 19, while maintaining a certain gap to prevent excessive friction from causing wear.

[0034] During the stamping process, when the punch presses against the aluminum pad, a huge impact force is generated. The buffer sleeve 21 can absorb part of the impact force and distribute it to the guide rod 18 and guide sleeve 19, thereby reducing the impact and vibration on the stamping table 4. The elastic material of the buffer sleeve 21 can deform, absorb and store energy, and slowly release the energy after the impact, allowing the stamping table 4 to return to its original position. This shock absorption effect helps protect the stamping table 4 and the mold from damage, while improving stamping accuracy and product quality.

[0035] Please refer to the following: Figure 4 , Figure 5 As an embodiment of the present utility model, the stamping table 4 is provided with a mounting hole at one end near the blanking hole 7, wherein a spring 23 is provided in the mounting hole; a movable pin 24 is provided at the upper end of the spring 23, wherein the top end of the movable pin 24 extends upward out of the mounting hole; an inclined surface is provided at the top end of the movable pin 24, wherein the lowest point of the inclined surface is close to the blanking hole 7 and is flush with the upper surface of the stamping table 4.

[0036] In the above-described scheme, a spring 23 is installed inside the mounting hole. The lower end of the spring 23 is fixed to the bottom of the mounting hole, and the upper end is connected to the movable pin 24. The function of the spring 23 is to provide elastic force, allowing the movable pin 24 to move up and down within a certain range. The movable pin 24 at the upper end of the spring 23 is a key component, which can move up and down under the action of the spring 23. The top end of the movable pin 24 extends upward out of the mounting hole to contact the material during the stamping process. An inclined surface is provided at the top end of the movable pin 24. The design of this inclined surface is very ingenious. The lower point is close to the side of the material drop hole 7 and is flush with the upper surface of the stamping table 4. This means that when the material slides over the stamping table 4, the strip-shaped scrap generated by the stamping will first contact the lower part of the inclined surface, thereby receiving an upward guiding force, which separates the scrap from the guide channel 10 and prevents the scrap from getting stuck in the guide channel 10 and affecting subsequent stamping operations. When the movable pin 24 is subjected to excessive impact force, the elastic force of the spring 23 can also play a buffering role, protecting the movable pin 24 and the stamping table 4 from damage. This design improves the durability and stability of the entire stamping device.
