Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die for processing electric vehicle shells. Background Technology

[0002] In the manufacturing system of electric vehicles, the processing of the vehicle shell is a crucial link. The electric vehicle shell not only needs to have an aesthetically pleasing design, but also needs to meet various functional requirements, such as installing electrical components and providing protection. Punching is one of the key processes to achieve these functions, as it can create various mounting holes, ventilation holes, and heat dissipation holes in the electric vehicle shell.

[0003] Traditional electric vehicle shell punching dies have a very simple structure, typically consisting of a fixed lower die and a manually operated upper die. The operator must manually place the shell onto the lower die and then manually apply pressure to lower the upper die to complete the punching.

[0004] Regarding the aforementioned technologies, it was found that the force and precision of manually operating the punching molds for electric vehicle shells are difficult to control, resulting in significant deviations in the size and position of the punching holes, inconsistent product quality, and a high scrap rate. Furthermore, manual operation is extremely inefficient and labor-intensive, failing to meet the demands of large-scale production.

[0005] Furthermore, existing electric vehicle shell punching dies typically generate a large amount of waste material that accumulates directly around the die during the punching process. This not only affects the cleanliness of the processing environment but also makes it easy for waste material to enter the moving parts of the die, causing wear or even damage and shortening its service life. Although some dies are equipped with simple waste collection troughs, cleaning the waste requires manual removal from the trough, which is cumbersome and incomplete. Residual waste material will affect the quality of subsequent punching. Utility Model Content

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, a punching die for processing electric vehicle shells includes a processing die base 1. A lower punching die 2 is fixedly mounted on the upper surface of the processing die base 1. A top plate 3 is positioned directly above the lower punching die 2. A rotating shaft seat 4, connected to the processing die base 1, is mounted on the lower surface of the top plate 3. The lower end of the rotating shaft seat 4 is fixedly connected to the processing die base 1, and the rotating shaft seat 4 is rotatably connected to the top plate 3. An upper punching die 5, which cooperates with the lower punching die 2, is slidably mounted on the lower surface of the top plate 3. A hydraulic cylinder 30, which drives the upper punching die 5 to rise and fall, is also fixedly mounted on the upper surface of the top plate 3. A retractable collection box 6 is provided in the middle of the lower punching die 2, and an auxiliary scraper 7 is slidably mounted in the collection box 6. The top plate 3 is rotatably connected to the processing die base 1 via the rotating shaft seat 4.

A hydraulic cylinder 30 is installed on the top base 3 of the equipment to drive the upper punching die 5 to rise and fall, enabling the upper punching die 5 to cooperate with the lower punching die 2 to complete the punching operation on the electric vehicle shell. This achieves a high degree of automation and improves processing efficiency. A pull-out collection box 6 is installed in the middle of the lower punching die 2 to facilitate the collection of waste generated during the punching process, maintaining a clean processing environment and facilitating waste cleaning and disposal. An auxiliary scraper 7 is slidably installed in the collection box 6 to assist in cleaning the waste inside, ensuring more thorough waste removal. The processing mold base 1 includes a base plate 11 and a fixed base 12. The fixed base 12 is installed on the upper surface of the base plate 11 and is fixedly connected to the base plate 11. Designing the processing mold base 1 with a structure where the base plate 11 and the fixed base 12 cooperate, the base plate 11 provides a stable support foundation during use, while the fixed base 12 is used to install components such as the lower punching die 2. This structural design makes the structure of the processing mold base 1 clearer and facilitates manufacturing, installation, and maintenance.

[0029] Reference Figure 2 As shown, the lower punching die 2 has several auxiliary punching holes 21. The upper punching die 5 includes a die block 51 and punching cutters 52 corresponding to the auxiliary punching holes 21. The punching cutters 52 are installed on the lower end face of the die block 51, and the die block 51 and the punching cutters 52 are fixedly connected. The lower punching die 2 has several auxiliary punching holes 21, and the punching cutters 52 of the upper punching die 5 correspond to these auxiliary punching holes 21. During the punching process, the punching cutters 52 can accurately pass through the auxiliary punching holes 21, ensuring the accuracy and quality of the punching and avoiding punching deviations. The fixed connection between the die block 51 and the punching cutters 52 ensures the stability of the punching cutters 52 during operation, preventing the cutters from loosening or shifting, and further improving the accuracy and reliability of the punching process.

[0030] Reference Figure 2 As shown, the top seat 3 of the equipment includes a main board seat 31 and a bushing 32 that rotatably engages with the rotating shaft seat 4. The bushing 32 is installed on the lower end face of the main board seat 31 and is fixedly connected to the main board seat 31. The top seat 3 of the equipment is divided into the main board seat 31 and the bushing 32. The bushing 32 rotatably engages with the rotating shaft seat 4, making the rotation of the top seat 3 of the equipment smoother. In addition, the equipment also needs to be equipped with a corresponding limit bracket during use to ensure that the lower punching die 2 and the upper punching die 5 can be stably aligned with each other when the top seat 3 of the equipment is flipped back.

[0031] Reference Figure 4 As shown, the collection box 6 includes a main body 61 and a lid 62. The lid 62 is installed on one side of the main body 61 and is fixedly connected to the main body 61.

The lid 62 can seal the main body 61 to prevent waste from overflowing during the collection process, and it also facilitates opening the lid 62 for waste disposal.

[0032] Reference Figure 5 As shown, the auxiliary scraper 7 includes a slide plate 71, a horizontal scraper seat 72, and a scraper 73. The horizontal scraper seat 72 is fixedly installed on the upper surface of the slide plate 71, and the scraper 73 is installed on the head of the horizontal scraper seat 72. Several locking bolts for locking the scraper 73 are installed on the horizontal scraper seat 72. The scraper 73 of the auxiliary scraper 7 is installed on the horizontal scraper seat 72 by locking bolts. This design allows the scraper 73 to be adjusted and replaced according to actual needs. The horizontal scraper seat 72 is fixedly installed on the slide plate 71, ensuring the stability of the scraper 73 during the cleaning process and effectively scraping away waste material below the auxiliary punch 21. Two sets of slide plates 71 are symmetrically installed in the main housing 61, allowing the slide plates 71 to slide on the guide shell 611. A support spring 711 is also fixedly installed on the lower surface of the slide plate 71. Two sets of guide shells 611 are symmetrically installed in the main box 61 for sliding installation of the slide plate 71. The guide shells 611 provide guidance for the sliding of the slide plate 71, ensuring smooth sliding of the auxiliary scraper 7 within the collection box 6. A support spring 711 is fixedly installed on the lower end face of the slide plate 71. The support spring 711 can play a role in buffering and supporting, ensuring that the scraper 73 on the auxiliary scraper 7 can stably fit against the lower die 2 of the auxiliary punch 21 to stably scrape the lower die 2 of the punch.

[0033] In this embodiment, during actual processing, the electric vehicle shell to be processed is placed on the lower punching die 2, and the hydraulic cylinder 30 on the top seat 3 of the equipment is activated. The hydraulic cylinder 30 drives the upper punching die 5 to slide downward. The die block 51 of the upper punching die 5 drives the punching cutter 52 to descend. Since the punching cutter 52 corresponds to the auxiliary punching hole 21 in the lower punching die 2, during the descent, the punching cutter 52 accurately passes through the auxiliary punching hole 21 to punch the electric vehicle shell. The waste generated during the punching process falls into the collection box 6 in the middle of the lower punching die 2 through the auxiliary punching hole 21.

[0034] When the waste material in the collection box 6 accumulates to a certain level, the collection box 6 can be pulled out from the punching die 2. During the pulling process, the scraper 73 on the auxiliary scraper 7 is stably attached to the bottom of the auxiliary punch 21. As the slide plate 71 slides, the scraper 73 effectively scrapes away the waste material remaining under the auxiliary punch 21, causing the waste material to fall into the collection box 6, making the waste material cleaning more thorough.

[0035] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
