[0002] Motor vehicles, especially automobiles, have become an important means of transportation in modern life. The stability of vehicle handling and driving is an important indicator of vehicle performance, and the damping performance of the shock absorption system between the vehicle body and axles directly affects the vehicle's stability. As an important component of the vehicle's shock absorption system, the leaf spring usually has multiple center holes to facilitate connection with the vehicle body. Due to the high hardness of the leaf spring material, specialized punching equipment is required.

[0003] In the production of leaf springs, punching holes on the side ends of the leaf springs is a common processing step. The traditional unloading method at the rear end of the punching die requires manual unloading, which results in a large workload and requires operators to spend a lot of time and energy on unloading. This often leads to problems such as low unloading efficiency and complicated operation, making it difficult to improve production efficiency.

[0023] 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.

[0024] like Figures 1 to 5 As shown, this utility model provides a quick pressing and unloading device for the rear end of the punching die for the side end hole of a leaf spring, including a punching table 1, a punching mechanism 12 mounted on the surface of the punching table 1, a mold mechanism 13 mounted on the surface of the punching table 1, and an unloading component 2 mounted on the surface of the punching table 1.

[0025] The unloading assembly 2 includes an unloading plate 21. The unloading plate 21 is slidably connected in a through groove on the surface of the mold mechanism 13. The surface of the stamping table 1 is provided with an unloading port that is compatible with the mold mechanism 13. Inclined blocks 22 are symmetrically installed on the surface of the unloading plate 21. A support frame 23 is installed on the surface of the stamping table 1. Hydraulic rods 24 are symmetrically installed on the surface of the support frame 23. The telescopic end of the hydraulic rod 24 passes through the support frame 23 and extends to the bottom of the support frame 23, and is connected to the pressing rod 25 located at the bottom of the support frame 23. A roller 26 is rotatably connected in a groove on the surface of the pressing rod 25. The roller 26 rolls on the surface of the inclined block 22. A receiving assembly 3 is installed at the unloading port on the surface of the stamping table 1, which facilitates the unloading of the leaf spring after punching, enabling uninterrupted unloading and avoiding manual unloading.

[0026] Specifically, a guide rod 27 is slidably connected in the through hole opened on the surface of the support frame 23. One end of the guide rod 27 passes through the support frame 23 and is connected to the unloading plate 21. The guide rod 27 can guide the movement of the unloading plate 21 and prevent the unloading plate 21 from shifting position during movement.

[0027] like Figures 1 to 5As shown, a reset spring 28 is sleeved on the surface of the guide rod 27. One end of the reset spring 28 is connected to the unloading plate 21, and the other end of the reset spring 28 is connected to the support frame 23. The reset spring 28 can drive the unloading plate 21 to reset, thus facilitating operation by the operator.

[0028] Furthermore, the unloading plate 21 is located on the unloading port opened on the surface of the stamping table 1, which facilitates the sealing and opening of the unloading port.

[0029] It is worth noting that after the two unloading plates 21 overlap, they are matched with the unloading port opened on the surface of the stamping table 1, thereby preventing the leaf spring from falling off from the unloading port.

[0030] like Figures 1 to 5 As shown, the receiving assembly 3 includes a receiving cylinder 31. The unloading port on the surface of the stamping table 1 is connected to the receiving cylinder 31. A connecting plate 32 is symmetrically installed on the surface of the receiving cylinder 31. A bolt 33 is threaded into a threaded hole on the surface of the connecting plate 32. One end of the bolt 33 passes through the connecting plate 32 and is threaded into the threaded hole on the surface of the stamping table 1. This allows for the collection and processing of the stamped leaf springs and scrap, and facilitates subsequent processing of the stamped leaf springs and scrap, greatly improving the efficiency of unloading and collecting the stamped leaf springs.

[0031] It is worth emphasizing that the two connecting plates 32 are distributed on both sides of the receiving cylinder 31 and are used to stabilize and fix the receiving cylinder 31.

[0032] Working principle and process: When punching a leaf spring, the leaf spring is first placed on the mold mechanism 13, and then the stamping mechanism 12 is started, which punches the leaf spring.

[0033] After the leaf spring is punched, the operator starts the hydraulic rod 24. The telescopic end of the hydraulic rod 24 drives the lower pressure rod 25 to rise. The lower pressure rod 25 moves upward continuously. When the unloading plate 21 blocks the unloading port on the surface of the stamping table 1, the guide rod 27 drives the return spring 28 to deform. As the lower pressure rod 25 moves upward, the unloading plate 21 is reset by the return spring 28. The unloading plate 21 drives the guide rod 27 to slide inside the support frame 23. The guide rod 27 can guide the movement of the unloading plate 21 to avoid positional deviation during movement. During the reset process, the unloading plate 21 drives the inclined block 22 to move. The unloading plate 21 then opens the unloading port on the surface of the stamping table 1, thereby unloading the stamped leaf spring. This facilitates the unloading of the punched leaf spring and allows for uninterrupted unloading, avoiding manual unloading.

[0034] When the unloading port on the surface of the stamping table 1 is blocked, the telescopic end of the hydraulic rod 24 drives the lower pressure rod 25 to press down. At this time, the roller 26 on the lower pressure rod 25 rolls on the surface of the inclined block 22. Due to the special shape of the inclined block 22 and the downward pressure of the lower pressure rod 25, the inclined block 22 drives the unloading plate 21 to move into the mold mechanism 13. When the unloading plate 21 moves, it drives the guide rod 27 to slide inside the support frame 23, which in turn drives the return spring 28 to deform. The return spring 28 can drive the unloading plate 21 to perform the reset process, which makes it convenient for the operator to use. When the unloading plate 21 blocks the unloading port on the surface of the stamping table 1, the leaf spring can be placed for stamping.

[0035] After stamping, the leaf springs and scrap fall into the receiving cylinder 31 through the unloading port on the surface of the stamping table 1. When the receiving cylinder 31 is full, the operator rotates the bolt 33 in the connecting plate 32, so that the bolt 33 is disengaged from the threaded hole on the surface of the stamping table 1, thereby disassembling the receiving cylinder 31. This facilitates the subsequent processing of the stamped leaf springs and scrap, and greatly improves the efficiency of unloading and collecting the stamped leaf springs.
