Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A stamping die for an automotive longitudinal beam includes a stamping mechanism 1, which comprises an upper die 14 and a lower die 15. Two limiting posts 16 are fixedly installed on the top of the upper die 14. A support mechanism 2 is provided above the stamping mechanism 1 to support the upper die 14. The support mechanism 2 includes: The pressure unit 21 is disposed above the upper mold 14 and includes a connecting sleeve 212 and a connecting seat 217. The connecting seat 217 is fixedly installed above the upper mold 14, and the connecting sleeve 212 is fixedly installed on the surface of the limiting post 16. A second support rod 216 is rotatably installed inside the connecting sleeve 212, and a first support rod 213 is rotatably installed on both sides of the connecting sleeve 212. The first support rod 213 and the second support rod 216 are slidably connected, and the upper mold 14 is supported by the second support rod 216 and the first support rod 213. The adjustment unit 22 is located on the outside of the second support rod 216 and the first support rod 213, and is used to adjust the distance between the second support rod 216 and the first support rod 213.

[0018] In this embodiment, a cross groove 214 is provided inside the first support rod 213, and a cross rod 215 is fixedly installed at one end of the second support rod 216. The cross rod 215 is slidably inserted into the cross groove 214. The second support rod 216 is limited to move by sliding the cross rod 215 inside the cross groove 214.

[0019] By sliding the cross rod 215 within the cross groove 214, the second support rod 216 is precisely positioned and moved, preventing it from deflecting or coming off during operation. This enhances the stability and reliability of the support structure and the transmission of force, thereby ensuring the centering and balance of the upper die 14 during the stamping process.

[0020] In this embodiment, the adjustment unit 22 includes an external threaded sleeve 221 fixedly installed on the surface of the first support rod 213, and an internal threaded rotating sleeve 222 rotatably installed on the surface of the second support rod 216. The internal threaded rotating sleeve 222 is threadedly rotatably installed on the surface of the external threaded sleeve 221.

[0021] By rotating the internal threaded swivel 222, the distance between it and the first support rod 213 can be finely adjusted, thereby flexibly adjusting the support preload of the upper die 14 to adapt to different stamping load requirements, improving the applicability and operational flexibility of the die.

[0022] In this embodiment, a knob 223 is fixedly mounted on the surface of the internal threaded sleeve 222 to provide a force point for the knob 223.

[0023] The knob 223 significantly improves the ease of operation of the adjustment unit 22, providing operators with a clear position for applying force, making the thread adjustment process more labor-saving and precise, avoiding slippage or inconvenience that may occur when directly rotating the internal threaded sleeve 222, and improving the efficiency of mold debugging and maintenance.

[0024] In this embodiment, a set of horizontal support rods 211 are fixedly installed above the upper mold 14 to improve the overall stress of the upper mold 14.

[0025] The addition of the cross brace 211 effectively enhances the structural rigidity and bending strength of the upper die 14, disperses the huge stress generated during the stamping process, and prevents the upper die 14 from elastic deformation or fatigue damage due to concentrated force in the middle, thereby extending the overall service life of the die and ensuring the forming quality of the stamped parts.

[0026] In this embodiment, the stamping mechanism 1 also includes a base frame 11. A fixed frame 12 is fixedly installed on the front side of the upright plate of the base frame 11, and a cylinder 13 is fixedly installed above the fixed frame 12. The output end of the cylinder 13 passes through the fixed frame 12 and is fixedly connected to the upper mold 14. The limiting post 16 slides inside the fixed frame 12, and the lower mold 15 is fixedly installed above the bottom plate of the base frame 11.

[0027] The base frame 11 and the fixed frame 12 provide robust support for the cylinder 13 and the mold. The cylinder 13 serves as a power source to drive the upper mold 14 to move up and down precisely. The limiting post 16 slides within the fixed frame 12 to ensure the guiding accuracy and repeatability of the stamping process, thereby ensuring the stability and efficiency of the automotive longitudinal beam stamping.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, firstly, rotate knob 223. Knob 223 drives the internal threaded sleeve 222 to rotate. The internal threaded sleeve 222 rotates on the surface of the external threaded sleeve 221. The internal threaded sleeve 222 pushes the second support rod 216. The second support rod 216 pushes the upper mold 14, thereby strengthening the support stress on the upper mold 14. Then, the material is placed inside the lower mold 15, and the cylinder 13 moves to drive the upper mold 14 to move down, and the upper mold 14 and the lower mold 15 are used for stamping and forming.
