Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive longitudinal beam reinforcement plate production technology, specifically to a stamping die for automotive longitudinal beam reinforcement plates. Background Technology
[0002] The longitudinal beam reinforcement plate is an important component of the vehicle body structure, typically used to enhance the rigidity and strength of the vehicle body. Especially in the event of a collision, it can effectively protect the safety of the occupants. The longitudinal beam reinforcement plate is usually a metal plate with a certain strength and rigidity, installed on the front and rear longitudinal beams of the vehicle. In short, the longitudinal beam reinforcement plate is an important part of the vehicle's passive safety system. By improving the rigidity and strength of the vehicle body, it provides additional protection for the occupants in the event of an accident.
[0003] A search revealed a utility model patent with publication number CN221336175U, which discloses a stamping die for a reinforcing component of an automotive longitudinal beam outer panel. The die includes a punch and a die, and further includes a base box slidably connected to the die. The base box has a groove in which several support mechanisms are slidably connected for elastic support of the die. The punch is connected to a fixing component, which connects and fixes the punch to the stamping mechanism. The base box is connected to a buffer component, which reduces the instantaneous acceleration of the punch when it falls, provided the fixing component causes the punch to drop. This utility model provides a stamping die for a reinforcing component of an automotive longitudinal beam outer panel. The fixing component connects and fixes the punch to the stamping mechanism, and the buffer component reduces the instantaneous acceleration of the punch when it falls, preventing excessive impact force between the punch and die and thus avoiding deformation of the reinforcing component.
[0004] However, the above design still has shortcomings. In the above design, when the punch falls, the buffer component can reduce the instantaneous acceleration of the punch when it falls, and avoid excessive impact force between the punch and the die. However, once the die is manufactured, its shape and size are fixed. If the product design needs to be changed, it is usually necessary to redesign and manufacture a new die. When punching with dies of different sizes, it is necessary to change the die, causing work to stop. To this end, we propose a stamping die for automotive longitudinal beam reinforcing plates to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die for automotive longitudinal beam reinforcement plates to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for an automotive longitudinal beam reinforcing plate, comprising a support box and a worktable, characterized in that: a rotating rod is slidably connected to the inner wall of the support box; a rotating valve is connected to the front side of the rotating rod; a support column is sleeved on the outer surface of the rotating rod; multiple stamping blocks are connected to the outer surface of the support column; a gear block is sleeved on the outer surface of the rotating rod; a gear set is connected to the inner wall of the support box; a limit post is connected to the outer surface of the rotating rod; and a limit plate is connected to the back side of the rotating rod.
[0007] The workbench has a control panel connected to its front side and a set of support legs installed on its bottom surface.
[0008] The upper surface of the support box is connected to multiple damping rods, and a return spring is sleeved on the outer surface of each damping rod.
[0009] The outer surfaces of the multiple damping rods are slidably connected to a connecting plate, and the bottom surface of the connecting plate is connected to the bottom surface of the return spring.
[0010] The upper surface of the workbench is connected to two cylinders, and each cylinder has a buffer spring fitted at its output end. The output ends of the two cylinders are connected to a support plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention ensures that the flat rotating rod can rotate by setting a pull-rotating valve 5, thereby ensuring that multiple molds can be replaced and adapting to the needs of products of different sizes or shapes to a certain extent, without the need to completely redesign and manufacture new molds. This avoids the need to change molds when punching with molds of different sizes, which would cause work stoppage. Pushing the rotating valve causes its gear block to mesh and fix with the gear set to prevent displacement. This design increases the adaptability of the mold, allowing the same set of molds to be used under different production needs. Attached Figure Description

[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a stamping die for a longitudinal beam reinforcing plate of an automobile, including a support box 1 and a worktable 4, characterized in that: a rotating rod 12 is slidably connected to the inner wall of the support box 1, a rotating valve 5 is connected to the front of the rotating rod 12, a support column 13 is sleeved on the outer surface of the rotating rod 12, a plurality of stamping blocks 11 are connected to the outer surface of the support column 13, a gear block 14 is sleeved on the outer surface of the rotating rod 12, a gear set 16 is connected to the inner wall of the support box 1, a limit post 17 is connected to the outer surface of the rotating rod 12, and a limit plate 15 is connected to the back of the rotating rod 12.
[0020] The front of the workbench 4 is connected to a control board 3. The control board 3 is usually used to install control components such as operation buttons, switches, and displays. This allows operators to control and monitor the mold in real time during the stamping process, improving the convenience and safety of operation. A set of support legs is installed on the bottom of the workbench 4.
[0021] The upper surface of the support box 1 is connected to multiple damping rods 6, and a return spring 10 is sleeved on the outer surface of each damping rod 6. The combination of damping rods 6 and return springs 10 can effectively absorb and reduce the impact and vibration generated during the stamping process, protect the mold and equipment, and extend their service life.
[0022] Among them, the outer surfaces of multiple damping rods 6 are slidably connected to a connecting plate 9. The bottom surface of the connecting plate 9 is connected to the bottom surface of the return spring 10. The connecting plate 9 can ensure that the pressure on the multiple damping rods 6 is evenly distributed during the stamping process, which can avoid mold damage or stamping quality degradation due to uneven pressure.
[0023] The upper surface of the workbench 4 is connected to two cylinders 2. The two cylinders 2 can work simultaneously and provide uniform pushing force through the support plate 7 to ensure the stability and consistency of the stamping process. Each cylinder 2 has a buffer spring 8 sleeved on its output end, and the output ends of the two cylinders 2 are connected to the support plate 7.
[0024] Working principle: During use, when the stamping process begins, the operator inputs a command on the control panel 3. The output end of cylinder 2 is fitted with a buffer spring 8 to reduce impact and vibration. At the same time, the output ends of the two cylinders 2 are connected to the support plate 7 to ensure uniform distribution of stamping force. As the cylinder 2 is pushed, multiple damping rods 6 on the support box 1 slide under the action of the return spring 10. The outer surfaces of the damping rods 6 are slidably connected to the connecting plate 9. The bottom surface of the connecting plate 9 is connected to the bottom surface of the return spring 10. This design ensures that the mold can be accurately reset at the end of the stamping cycle. By pulling the rotary valve 5 to disengage the gear block 14 from the gear set 16, the rotating rod 12 can be stably rotated, thereby ensuring the adjustment of the support column 13 and multiple stamping blocks 11. Once the mold is manufactured, its shape and size are fixed. If the product design needs to be changed, a new mold usually needs to be redesigned and manufactured. When punching holes with molds of different sizes, the mold needs to be changed, causing work to stop.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
