Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping forming device for automotive seals. Background Technology

[0002] Automotive seals are key components in automobiles used to prevent leakage of liquids, gases, or dust. Their core function is to achieve a sealing effect through an elastic structure. The main types of automotive seals include rubber seals, plastic seals, metal seals, and composite seals. To improve the wear resistance of seals, composite seals with metal skeletons are generally used. In the processing and manufacturing of composite seals with metal skeletons, a stamping forming device is required to stamp and form the metal skeleton to facilitate subsequent processing of the metal skeleton.

[0003] A patent entitled "A Shell Stamping Device" (patent application number: 202320128829.4) discloses a shell stamping device, relating to the field of stamping technology. The device includes a base plate, a top plate above the base plate, a lifting plate between the top and bottom plates, a mold groove on the top of the base plate, a U-shaped limiting plate fixed to the top of the base plate, clamping plates fixed to the bottom and near both sides of the lifting plate, the clamping plates located inside the U-shaped limiting plates, a cylinder fixed to the top of the lifting plate, the output end of the cylinder penetrating the lifting plate and fixed to a stamping head; a lifting assembly fixedly installed between the base plate and the top plate; and a part-retrieving assembly fixedly installed at the bottom of the base plate. A drive motor rotates a screw, which lowers the lifting plate, causing the clamping plates to press against a metal frame, thus fixing the metal frame and preventing it from shifting during the stamping process.

[0004] In the aforementioned cases, it is difficult to buffer the impact force generated during stamping, and the material is prone to deformation due to excessive impact force. This reduces the stamping effect of the stamping device and causes wear between the dies, thus reducing the protection of the dies. Therefore, it is necessary to propose a stamping forming device for automotive seals to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping and forming device for automotive seals, so as to solve the problems mentioned in the background art, such as the difficulty in buffering the impact force generated by stamping, the easy deformation of materials due to excessive impact force, the reduction of the stamping effect of the stamping device on the material, and the wear between the molds due to excessive impact force, thereby reducing the protection of the mold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping and forming device for automotive seals, comprising a base, a support rod fixedly connected to the top of the base, and a lower mold fixedly connected to the top of the base, a fixed plate fixedly connected to the top of the support rod, a hydraulic cylinder fixedly connected inside the fixed plate, a movable plate fixedly connected to the telescopic end of the hydraulic cylinder, and an upper mold fixedly connected to the bottom of the movable plate.

[0007] The top of the movable plate is provided with a limit buffer assembly, which includes a connecting plate, a movable spring and a limit block. The bottom of the connecting plate is fixedly connected to the top of the movable plate, and the outside of the connecting plate is fixedly connected to the top of the movable spring. The bottom of the movable spring is fixedly connected to the top of the limit block.

[0008] The lower mold is equipped with a material-receiving buffer assembly, which includes a buffer spring, a buffer plate, and a rubber buffer block. The bottom end of the buffer spring is fixedly connected to the bottom of the inner cavity of the lower mold, and the top end of the buffer spring is fixedly connected to the bottom of the buffer plate. The bottom of the buffer plate is fixedly connected to the top of the rubber buffer block.

[0009] Preferably, the outer side of the limiting block is slidably connected to the inner side of the moving plate, and the height of the limiting block is greater than the height of the upper mold.

[0010] Preferably, the number of the limiting buffer components is two sets, and the two sets of limiting buffer components are located on one side and the other side of the upper mold, respectively.

[0011] Preferably, the outer side of the buffer plate is slidably connected to the inner side of the lower mold, and the bottom of the rubber buffer block is fixedly connected to the bottom of the inner cavity of the lower mold.

[0012] Preferably, the interior of the movable plate is slidably connected to the exterior of the support rod, and the hydraulic cylinder is located at the center of the top of the movable plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By combining the limiting buffer assembly and the material handling buffer assembly, the metal skeleton can be placed on top of the lower die during stamping. Since the height of the limiting block is greater than that of the upper die, the limiting block will contact the metal skeleton first, limiting its movement and preventing it from shifting during stamping. This improves the stamping effect. Simultaneously, the movable spring can buffer the stamping force, reducing wear between the upper and lower dies and enhancing die protection. Furthermore, the combination of the buffer spring and the rubber buffer block further buffers the stamping force, preventing deformation of the metal skeleton due to excessive pressure. The reaction force of the buffer spring also facilitates the handling of the stamped metal skeleton, making the device more convenient and practical. Attached Figure Description

[0020] 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.

[0021] This utility model provides, for example Figure 1 - Figure 4The illustrated automotive seal stamping forming device includes a base 1, a support rod 2 fixedly connected to the top of the base 1, and a lower mold 7 fixedly connected to the top of the base 1. A fixed plate 3 is fixedly connected to the top of the support rod 2, and a hydraulic cylinder 4 is fixedly connected inside the fixed plate 3. A movable plate 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4, and an upper mold 6 is fixedly connected to the bottom of the movable plate 5. The interior of the movable plate 5 is slidably connected to the exterior of the support rod 2, and the hydraulic cylinder 4 is located at the middle of the top of the movable plate 5. When stamping a metal frame, the metal frame can be placed on top of the lower mold 7. When the hydraulic cylinder 4 is opened, the hydraulic cylinder 4 will drive the upper mold 6 downward through the movable plate 5, causing the upper mold 6 to enter the interior of the lower mold 7 to stamp the metal frame.

[0022] In addition, a limiting buffer assembly is provided on the top of the movable plate 5. The limiting buffer assembly includes a connecting plate 8, a movable spring 9, and a limiting block 10. The bottom of the connecting plate 8 is fixedly connected to the top of the movable plate 5, and the outside of the connecting plate 8 is fixedly connected to the top of the movable spring 9. The bottom of the movable spring 9 is fixedly connected to the top of the limiting block 10, and the outside of the limiting block 10 is slidably connected to the inside of the movable plate 5. The height of the limiting block 10 is greater than the height of the upper mold 6. There are two sets of limiting buffer assemblies, located on one side and the other side of the upper mold 6, respectively. Because the height of the limiting block 10 is greater than the height of the upper mold 6, the limiting block 10 will contact the metal frame first, limiting the metal frame and preventing it from shifting during stamping. This improves the stamping effect on the metal frame. At the same time, the movable spring 9 can be used to buffer the stamping pressure, reducing wear between the upper mold 6 and the lower mold 7 and improving the protection of the mold.

[0023] Finally, the lower mold 7 is equipped with a material-retrieving buffer assembly, which includes a buffer spring 11, a buffer plate 12, and a rubber buffer block 13. The bottom end of the buffer spring 11 is fixedly connected to the bottom of the inner cavity of the lower mold 7, and the top end of the buffer spring 11 is fixedly connected to the bottom of the buffer plate 12. The bottom end of the buffer plate 12 is fixedly connected to the top of the rubber buffer block 13. The outside of the buffer plate 12 is slidably connected to the inside of the lower mold 7, and the bottom of the rubber buffer block 13 is fixedly connected to the bottom of the inner cavity of the lower mold 7. The cooperation of the buffer spring 11 and the rubber buffer block 13 can further buffer the stamping pressure, avoiding the problem of deformation of the metal frame due to excessive stamping pressure. At the same time, after the stamping is completed, the buffer spring 11 will restore its elasticity, thereby driving the buffer plate 12 to move upward. The buffer plate 12 will move the stamped metal frame upward, facilitating the material retrieval of the metal frame, which brings convenience to the use of the device and improves its practicality.

[0024] Working principle: When stamping a metal frame, the metal frame can be placed on top of the lower mold 7. The hydraulic cylinder 4 is opened, and it moves the upper mold 6 downwards via the moving plate 5. Since the height of the limiting block 10 is greater than that of the upper mold 6, the limiting block 10 will contact the metal frame first, limiting its movement and preventing it from shifting during stamping. This improves the stamping effect. Simultaneously, the movable spring 9 buffers the stamping pressure, reducing wear between the upper mold 6 and the lower mold 7 and improving mold protection. The buffer spring 11 and rubber buffer block 13 further buffer the stamping pressure, preventing excessive pressure from deforming the metal frame. After stamping, the buffer spring 11 returns to its elasticity, causing the buffer plate 12 to move upwards. The buffer plate 12 then moves the stamped metal frame upwards, facilitating material removal and improving the device's usability.
