[0021] 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.

[0022] Please see Figure 1-4 A punching device for automotive panel films includes a support base 1 and a lower mold 11. A rotating disk 2 is arranged above the support base 1. The rotating disk 2 has several rectangular clearance holes 21. A rectangular ring 3 is slidably connected to the inner wall of each of the rectangular clearance holes 21. A horizontal plate 31 is installed on both sides of the rectangular ring 3. A guide rod 32 is installed at one end of the horizontal plate 31. The guide rod 32 passes through the top of the rotating disk 2. An end plate 321 is installed at the top of the guide rod 32. A return spring 33 is installed at the bottom of the end plate 321. The return spring 33 contacts the top of the rotating disk 2 and is sleeved on the outside of the guide rod 32.

[0023] It should be noted that, in this embodiment, the upper die descends and presses the rectangular ring 3 during punching, and the rectangular ring 3 descends together, so that the car panel can be fitted and contacted with the lower die 11. After punching, the return spring 33 pushes the end plate 321, and the rectangular ring 3 rises together, so that the car panel and the remaining material can be lifted together. As the rotary disk 2 rotates, the new panel can be rotated between the two dies. The punched panel is rotated to a region away from the punching area for replacement, which is safer.

[0024] Specifically, during operation, the car panel with the protective film applied is first placed on the rectangular ring 3 on the rotating disk 2 to ensure accurate positioning. As the rotating disk 2 rotates, it switches to the position above the lower die 11. During punching, the upper die moves downward, and the rectangular ring 3, under the force of the punching, moves the horizontal plate 31 and guide rod 32 downward. The return spring 33 is compressed, and the car panel moves downward with the rectangular ring 3 to contact the lower die 11. The upper die continues to press down to complete the punching. After the punching is completed, the upper die resets, and the return spring 33 elastically recovers, pushing the end plate 321 and guide rod 32 upward, which in turn drives the horizontal plate 31 and rectangular ring 3 to rise, placing the car panel and remaining material... The material is lifted and separated from the lower mold 11. Then the rotary table 2 rotates, moving the new panel to be processed to the stamping station. At the same time, the panel after punching is moved to an area away from the stamping station. In this area, the operator can easily remove the car panel. The remaining material is pushed up by the rectangular ring 3 and will not be trapped outside the lower mold 11. In this way, the rotation of the rotary table 2 enables a quick switch between the panel to be processed and the already processed panel, eliminating the time-consuming processes of panel positioning calibration and mold adaptation adjustment during traditional replacement. This greatly shortens the downtime of the equipment and improves production efficiency. On the other hand, the remaining material after punching is lifted and transferred with the car panel by the rectangular ring 3, making it convenient to remove the remaining material.

[0025] In one embodiment of this utility model, such as Figures 1-4 As shown, the rotating disk 2 has several through holes 22 and several lower notches 23. The horizontal plate 31 is engaged with the inner wall of the corresponding lower notch 23, and the guide rod 32 is slidably connected to the inner wall of the corresponding through hole 22.

[0026] Specifically, the perforation 22 on the rotating disk 2 provides a sliding channel for the guide rod 32, ensuring that the guide rod 32 will not deviate during its up-and-down movement, making the movement of the guide rod 32 more stable and precise. The lower notch 23 acts as a locking and limiting mechanism for the horizontal plate 31, allowing the horizontal plate 31 to be stably connected to the rectangular ring 3. When the rectangular ring 3 moves up and down, the horizontal plate 31 can slide smoothly along the inner wall of the lower notch 23, thereby ensuring the stability of the overall structure and the accuracy of movement when the rectangular ring 3 drives the car panel to perform punching and lifting actions. This further ensures the precision of the punching process and the smoothness of subsequent transfer and removal of the car panel and scrap materials.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, four shielding wedges 34 are installed on the top edge of the rectangular ring 3 to shield and position the car panel.

[0028] Specifically, the four shielding wedges 34 installed on the top edge of the rectangular ring 3 can shield and limit the movement of the car panel from all sides. When the car panel with the protective film attached is placed inside the rectangular ring 3, the four shielding wedges 34 can restrict the horizontal movement of the car panel, ensuring that the car panel is accurately positioned within the rectangular ring 3. This prevents the punching accuracy from being affected by positional deviations before punching, thus ensuring that the car panel produced by subsequent punching meets the design dimensions and assembly requirements, and improving the accuracy and reliability of punching.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, four movable wedges 35 are slidably connected to the inner side of the bottom of the rectangular ring 3. A spring is installed between the movable wedges 35 and the rectangular ring 3. When the movable wedges 35 come into contact with the edge of the lower mold 11, they retract into the interior of the rectangular ring 3.

[0030] Specifically, after the punching process starts, the rectangular ring 3 moves downward with the upper die pressing down. The movable wedge 35 first contacts the edge of the lower die 11. The squeezing force generated by the lower die 11 overcomes the spring force, causing the movable wedge 35 to retract into the rectangular ring 3. This avoids hindering the precise fit between the rectangular ring 3 and the lower die 11, and also leaves space for the car panel to fully contact the lower die 11, ensuring smooth punching. After punching, the rectangular ring 3 is lifted upward under the action of the return spring 33. The movable wedge 35 disengages from the lower die 11 with the rectangular ring 3. The squeezing force disappears, and the spring returns to its elastic deformation, pushing the movable wedge 35 to extend outward again. At this time, the extended movable wedge 35 can block and limit the bottom of the finished car panel inside the rectangular ring 3, effectively preventing the panel from falling during the lifting of the rectangular ring 3 and the rotation of the rotating disk 2, ensuring the stability of the finished product transfer. When picking up the part away from the punching area, it is only necessary to slightly lift the panel upward to overcome the limitation of the movable wedge 35, without affecting the part picking operation.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, a drive unit 4 is installed at the top of the rotating disk 2, and the output end of the drive unit 4 is installed at the center of the bottom end of the rotating disk 2. The rotating disk 2 is higher than the lower mold 11.

[0032] Specifically, the drive unit 4 is a motor. The drive unit 4, installed at the top of the rotary disk 2, provides the power source for the rotation of the rotary disk 2. Its output end is connected to the center of the bottom end of the rotary disk 2, which can precisely drive the rotary disk 2 to rotate stably around the central axis, realizing the switching control of different rectangular ring 3 stations on the rotary disk 2. That is, it can accurately rotate the rectangular ring 3 with the new car panel to be processed to the stamping station between the upper and lower dies, and at the same time rotate the rectangular ring 3 containing the stamped panel and the scrap material to the area away from the stamping, ensuring the efficiency and accuracy of station switching. The design of the rotary disk 2 being higher than the lower die 11 provides sufficient space for the rectangular ring 3 to rotate with the rotary disk 2, avoiding collision and interference between the rotary disk 2 and the lower die 11 when rotating. On the other hand, it also reserves stroke for the downward movement of the rectangular ring 3 during stamping, ensuring that the rectangular ring 3 can smoothly drive the car panel to fit and contact the lower die 11 during the stamping process, ensuring the normal operation of the stamping process, and further improving the stability and smoothness of the entire stamping device.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, a transparent shielding plate 5 is installed at the top of the support base 1, and the bottom side of the transparent shielding plate 5 is higher than the top of the guide rod 32.

[0034] Specifically, the transparent baffle 5 provides physical protection for the core moving parts of the punching device, such as the rotary disk 2, rectangular ring 3, and guide rod 32, preventing external debris from falling into the device and affecting the mechanical operation accuracy. It also prevents the splashing of diaphragm residue generated during the punching process and the safety risks caused by operators accidentally touching moving parts. On the other hand, the transparent material design ensures that operators can clearly observe the punching progress, panel positioning status, and finished product transfer inside the device. The processing process can be monitored in real time without removing the baffle, making it easy to detect and handle abnormal problems in a timely manner. Furthermore, the design of the bottom side of the transparent baffle 5 being higher than the top of the guide rod 32 provides sufficient space for the guide rod 32 to move up and down with the rectangular ring 3, preventing collisions and interference between the baffle 5 and the guide rod 32. This ensures the realization of the protective function without affecting the normal movement of the core components of the device, further improving the safety and monitorability of the punching device operation.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working Principle: When this automotive panel film punching device is in operation, the automotive panel with protective film attached is first placed into the rectangular ring 3 of the rotating disk 2. Four blocking wedges 34 at the top of the rectangular ring 3 limit the panel's position from all sides, while the movable wedge 35 at the bottom extends under spring action for auxiliary positioning, ensuring accurate panel positioning. The drive unit 4 drives the rotating disk 2 to rotate, moving the panel to be processed above the lower mold 11. The upper mold presses down on the rectangular ring 3, causing the rectangular ring 3 to move the horizontal plate 31 and guide rod 32 downwards. The horizontal plate 31 slides along the lower notch 23, and the guide rod 32 moves smoothly along the through hole 22. The return spring 33 is compressed, and simultaneously, the movable wedge 35 retracts after contacting the lower mold 11, causing the panel to adhere to the lower mold 11 and completing the punching. After punching, the upper mold resets, and the return spring 33 pushes the guide rod 32 and rectangular ring 3 upwards. The movable wedge 35 extends to block the panel from falling. The rotating disk 2 rotates the finished product away from the punching area, allowing the operator to remove the panel. Excess material is transferred with the panel and not placed on the lower mold 11. The transparent shield 5 on the support base 1 is a protective component that is easy to observe and does not interfere with the movement of the guide rod 32, thus achieving efficient punching and safe operation.
