[0002] Stamping dies for automotive parts processing are essential industrial tools used to form sheet metal into the desired part shape during the cold stamping process. Common stamping dies include blanking dies, bending dies, drawing dies, and forming dies. During the stamping process, the sheet metal is placed within the die cavity, and the punch contacts and applies pressure to the die cavity under the action of the press.

[0003] The guide structure is a critical component of the stamping die, ensuring stable operation and accurate positioning during high-speed, high-precision stamping. However, the guide structure wears out due to contact and friction during frequent stamping, affecting precision and stability, and even causing mechanical failure. As wear increases, the gap between the guide structure and the die body increases, causing wobble during the stamping process, affecting the dimensional accuracy and surface quality of the stamped part, while also accelerating wear on other parts of the die.

[0004] Looseness and shaking of the guide structure can directly affect the overall stability of the mold, causing deformation, cracking, or even scrapping of the mold, seriously affecting production efficiency and product quality. Therefore, regular maintenance and inspection of the guide structure to ensure its good condition is crucial to ensuring the normal operation of the stamping mold and product quality.

[0026] The following is a clear and complete description of the technical solution of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example

[0027] See also Figure 1 - Figure 4 The figure shows a stamping die used for automotive parts processing. The die consists of two core components: a lower die 1 and an upper die 2. These two components precisely coordinate to complete the stamping and forming of automotive parts. The upper die 2 sits firmly above the lower die 1, and the two work closely together to create an efficient and precise stamping platform.

[0028] To ensure the mold maintains extremely high guiding accuracy during high-speed stamping, the design team cleverly incorporated a robust guide device 3 at the mold's corners. This device consists of a guide base tube 31 and a guide post 33, fixed to the upper corner of the lower mold 1 and the lower corner of the upper mold 2, respectively. The guide post 33 precisely inserts into the guide base tube 31, forming a stable guide connection that effectively prevents the mold from shifting and shaking during the stamping process.

[0029] In order to further enhance the stability of the guide device, the design team installed a first blocking ring 32 on the guide base tube 31, and a second blocking ring 34 on the guide column 33. These two blocking rings not only play a limiting role, but also achieve a tight connection with the mold body through the connecting screw ring 35. A number of "L"-shaped tightening blocks 36 are cleverly distributed on the side wall of the connecting screw ring 35. These tightening blocks 36 are connected to the fastening bolts 38 through waist holes 37, ensuring a firm fixation between the screw ring and the mold. It is worth noting that an anti-slip gasket is also provided on the fastening bolt 38. This thoughtful design effectively prevents the bolt from loosening during long-term use.

[0030] It's worth noting that the first blocking ring 32 and guide base tube 31, as well as the second blocking ring 34 and guide post 33, all utilize an integrated design. This not only simplifies the manufacturing process but also significantly enhances the mold's overall strength and durability. Furthermore, the blocking rings on both the guide base tube 31 and guide post 33 are threaded, allowing the connecting screw ring 35 to be easily connected via threads. This facilitates installation and removal while ensuring a reliable and stable connection.

[0031] Multiple abutment blocks 36 are distributed in a circular pattern around the connecting screw ring 35. This layout not only ensures more uniform force distribution but also enhances the overall rigidity of the mold. A notch is provided at the inner end of the abutment block 36, cleverly aligning with the connecting screw ring 35. Through welding, a seamless connection is achieved between the screw ring and the abutment block 36. This connection is not only secure and reliable, but also absorbs impact forces during the stamping process to a certain extent, protecting the mold from damage.

[0032] In practical applications, this stamping die, with its superior guiding precision and stability, has significantly improved the processing quality and production efficiency of automotive parts. Furthermore, its simple structural design and convenient maintenance have won the favor of numerous manufacturers. In the future, as the automotive manufacturing industry continues to develop and upgrade, this stamping die is expected to be more widely used and promoted.

[0033] The installation process is as follows: make sure that the lower mold 1 and the upper mold 2 are in the appropriate position, and clean all parts of the guide device, including the guide base tube 31, the guide column 33, the first blocking ring 32, the second blocking ring 34, the connecting screw ring 35, the tightening block 36, the fastening bolts 38 and the anti-slip gasket.

[0034] The guide base tube 31 is fixed to the upper corner of the lower mold 1, ensuring accurate and stable installation. The first blocking ring 32 is integrally mounted on the guide base tube 31. The guide post 33 is precisely inserted into the lower corner of the upper mold 2, ensuring smooth docking with the guide base tube 31. The guide post 33 and second blocking ring 34 are integrated into one design.

[0035] Thread the connecting screw ring 35 into the guide tube 31 and guide post 33 through their threads, connecting them. At this point, align the multiple L-shaped retaining blocks 36 on the sidewalls of the screw ring. Insert the fastening bolts 38 through the waist holes 37 and connect them to the retaining blocks 36. Use non-slip washers to prevent the bolts from loosening. Tighten the bolts one by one to ensure a secure connection between the connecting screw ring 35 and the mold body.

[0036] After installation, check that all guide components are in place and free of looseness or deviation. Adjustments are made as necessary to ensure guide accuracy and stability. A die press test is performed to verify the guide's performance during high-speed stamping, ensuring no deviation or wobble occurs. The guide structure in the stamping die is now installed and ready for full production use.
