The thickness of the slide plate 31 is greater than that of the positioning protrusion 37, and the bottom of the positioning protrusion 37 abuts against the punching table 2.

[0038] In a specific embodiment of the present invention, the punching limit assembly 4 includes a support frame 41, a drive cylinder 42, a punching frame 43, and a top column 44. The support frame 41 is fixed to the top surface of the base 1. The drive cylinder 42 is fixed to the top center of the support frame 41 and passes through the support frame 41 and the punching frame 43 to fix and drive the punching frame 43 to move up and down. The drive cylinder 42 can be an electric hydraulic cylinder. The mounting position is provided at the bottom of the punching frame 43. The mounting position is detachably connected to the mounting baffle 45 by bolts. The mounting baffle 45 abuts against the punching die 5 and fixes the punching die 5. The bottom of the punching frame 43 is also provided with a punching slide 431 that is slidably connected to the top column 44. The punching slide 431 contains a punching spring 46 that is connected to both the top column 44 and the punching frame 43.

[0039] In this embodiment, both sides of the punching frame 43 are slidably connected to punching guide posts 47 fixed to the punching table 2. The movement limit assembly 3 is disposed between the two punching guide posts 47. A top post 44 is provided on both sides of the punching die 5, and the punching chute 431 corresponds to each top post 44.

[0040] In this embodiment, a mounting block 51 is fixedly connected to the top of the punching die 5 and adapted to the mounting position. The mounting block 51 has a rectangular cross-section. Any device that can achieve the aforementioned performance and functions of the punching die 5 and the punching frame 43 is within the scope of protection of this application.

[0041] Compared with the prior art, this type of punching equipment for automobile decorative panels can adjust the position of the punching hole 311 relative to the punching die 5 through the slidable movable limit assembly 3. By selecting the punching die 5 of the corresponding shape, different shapes of punching holes can be obtained, which has a wider range of applications. The setting of the limit plate 33 can further achieve the positioning of the two sides of the decorative panel 6. By coordinating the structures such as the slide plate 31 and the pressure plate 32 in the movable limit assembly 3, the decorative panel 6 can be extruded and limited in the same shape as the punching hole above and below, ensuring the support effect of the punching edge position, avoiding deformation or damage of the decorative panel 6 caused by the punching pressure, and ensuring the punching effect. By coordinating the top column 44 and the pressure plate 32 in the punching limit assembly 4, the drive cylinder 42 can be used to simultaneously achieve downward pressure limiting and punching. At the same time, during the downward pressure process, the top column 44 first contacts the pressure plate 32 and presses the pressure plate 32 downward to achieve the limit fixation of the decorative panel 6 before punching, which improves the limit fixation effect.

[0042] The operating process of the punching equipment for automotive decorative panels of the present invention is as follows: Taking a flat decorative panel as an example, select a corresponding punching die 5 according to the required punching shape, place it in the installation position, place the mounting baffle 45 against the punching die 5, and secure it to the punching frame 43 with bolts. Pull all the positioning posts 38 upward and rotate them until the handle rests on the slide 31. Push the slide 31, adjust the position of the movable limit assembly 3 so that the punching hole 311 of the corresponding shape is aligned with the punching die 5, rotate the positioning posts 38, and let them fall freely to engage with the positioning holes 22, thus securing the slide 31. Place the decorative panel 6 on top of the slide 31, and adjust the position of the two limit plates 33 according to the size of the decorative panel 6. The adjusted limit plates 33 are secured with fasteners 332. At this point, the decorative panel 6 is located between the two limit plates 33. The drive cylinder 42 is activated, driving the punching frame 43 downward. The top post 44 first contacts the pressure plate 32 and presses it downward until it contacts the decorative panel 6. At this point, the limit spring 36 is compressed, and the decorative panel 6 is fixed between the slide 31 and the pressure plate 32. The punching frame 43 continues to move downward, driving the punching die 5 downward to punch the decorative panel 6. The punching spring 46 is now compressed, and the punched waste enters the waste hole 23 and slides along the guide hole 24 into the waste box 7. After punching is completed, the drive cylinder 42 drives the punching frame 43 upward. The punching die 5 first rises and separates from the decorative panel 6. At this point, the pressure plate 32 and the top post 44 are still in contact, limiting the position of the decorative panel 6. The driving cylinder 42 continues to rise until the punching spring 46 is fully released, and the top column 44 rises together with the punching frame 43. The pressing plate 32 moves upward and separates from the decorative panel 6 under the action of the limit spring 36, and the punched decorative panel 6 is obtained. The punched flat decorative panel is then thermoformed to obtain the desired special-shaped decorative panel.

[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0044] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
