Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing equipment technology, and in particular to a stamping device for the co-line production of side panels of models with different roof heights. Background Technology

[0002] In the automotive manufacturing industry, the production of vehicle side panels mostly relies on stamping equipment. For stamping equipment that produces side panels of different roof heights on the same production line, its core function is to realize the stamping processing of the outer panels of side panels of different roof heights in order to meet the needs of the automotive production line for the production of different vehicle parts. As a commonly used commercial and passenger vehicle, light passenger vehicles need to be designed to fully consider the usage needs of different customers. This often leads to different roof heights being designed for light passenger vehicles. Taking a certain light passenger vehicle as an example, it is designed with both low-roof and medium-roof models. However, under current production conditions, due to the differences in the shape and size of the side panels of the different roof height models, it is necessary to set up specific molds for the low-roof and medium-roof models, which increases costs and presents limitations. The reason for this problem is that most existing stamping dies are specialized dies with fixed parameters such as the shape and position of the stamping head. They can only be adapted to the stamping requirements of the side panels of a single type of high-roof vehicle and cannot be flexibly adjusted to adapt to the production of different high-roof models. Designing and manufacturing a new die requires multiple stages, including preliminary design and development, material procurement, processing and manufacturing, and debugging and testing. The investment in these stages significantly increases the cost of die development and presents limitations. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] This utility model provides, for example Figures 1 to 2 The stamping device shown is used for the co-line production of side panels of different roof height models. It includes a stamping die body 1, which is composed of a die base 11 and an upper die 12. The interior of the stamping die body 1 includes an adjustment unit 2, which includes a middle roof side panel stamping head 21, a low roof side panel stamping head 22 and a push-pull cylinder 23. The middle top side panel stamping head 21 is located on one side inside the upper mold 12, and the low top side panel stamping head 22 is located on one side of the middle top side panel stamping head 21. Multiple sets of push-pull cylinders 23 are fixedly assembled inside the upper mold 12. The output shafts of the push-pull cylinders 23 are fixedly assembled with the middle top side panel stamping head 21 and the low top side panel stamping head 22, respectively.

[0017] Example 1: In this embodiment, the metal sheet to be processed is placed flat in the guide groove 25, and the edge of the sheet must be aligned with the side wall of the guide groove 25 to ensure accurate subsequent stamping position. The servo cylinder 27 is started, and the output shaft of the servo cylinder 27 pushes the baffle 26 upward until the baffle 26 is tightly attached to the lower surface of the sheet. At this time, the drawing head 24 moves downward with the upper die 12 and cooperates with the baffle 26 to perform drawing processing on the sheet to meet the specific shape requirements of the side panel. Subsequently, the side panel is pushed to one side by the subsequent sheet. Then, the main switch of the equipment is started, and the upper die 12 begins to move downward under the drive of the hydraulic press. At this time, the guide head 14 slides synchronously along the guide column 15 to provide precise guidance for the movement of the upper die 12 and prevent the upper die 12 from deviating. At the same time, the support plate 13 is movably connected to the upper die 12 through the connecting rod and moves downward with the upper die 12, always providing stable support for the upper die 12. When the stamping head contacts the surface of the sheet metal, it begins to stamp and shape the sheet. During the stamping process, scrap material generated falls into the corresponding scrap hole 28 under the stamping pressure and is discharged through the scrap hole 28 to the scrap collection device below the mold base 11. After the stamping and drawing operations are completed, the device is reset, and the operator removes the finished side panel from the guide groove 25, thus ending the entire stamping process.

[0018] Figure 1 , Figure 3 , Figure 4 and Figure 5 The stamping device shown is used for the co-line production of side panels of different roof height models. It includes a stamping die body 1, which is composed of a die base 11 and an upper die 12. The interior of the stamping die body 1 includes an adjustment unit 2, which includes a middle roof side panel stamping head 21, a low roof side panel stamping head 22 and a push-pull cylinder 23. The middle top side panel stamping head 21 is located on one side inside the upper mold 12, and the low top side panel stamping head 22 is located on one side of the middle top side panel stamping head 21. Multiple sets of push-pull cylinders 23 are fixedly assembled inside the upper mold 12. The output shafts of the push-pull cylinders 23 are fixedly assembled with the middle top side panel stamping head 21 and the low top side panel stamping head 22, respectively.

[0019] A support plate 13 is provided between the mold base 11 and the upper mold 12. A connecting rod is fixedly mounted on the support plate 13 and is movably engaged inside the upper mold 12. A guide head 14 is fixedly mounted at the bottom of the upper mold 12, and a guide post 15 is fixedly mounted at the top of the mold base 11. The guide post 15 is slidably connected inside the guide head 14. A spring 16 is wound around the outer surface of the guide post 15, and the end of the spring 16 abuts against the guide head 14. A drawing head 24 is fixedly mounted on one side of the upper mold 12 and passes through the support plate 13. A guide groove 25 is provided inside the mold base 11, and a baffle 26 is vertically slidably connected inside the guide groove 25. A servo cylinder 27 is fixedly mounted at the bottom of the mold base 11, and the output shaft of the servo cylinder 27 is fixedly mounted to the baffle 26. The baffle 26 and the drawing head 24 are used together to enable the drawing operation of the sheet metal. The inside of the guide trough 25 has multiple sets of waste holes 28, which correspond from right to left to the stamping head 21 of the middle top side panel and the stamping head 22 of the low top side panel.

[0020] Example 2: In this embodiment, when it is necessary to produce the outer side panel of the middle-roof model, the operator sends a middle-roof stamping command through the PLC control cabinet of the device. After receiving the command, the control system sends a retraction signal to the push-pull cylinder 23 connected to the low-roof outer side panel stamping head 22. The output shaft of the push-pull cylinder 23 retracts, driving the low-roof outer side panel stamping head 22 to move into the non-working area inside the upper mold 12 until it is completely out of the stamping operation range. At the same time, the control system sends an extension signal to the push-pull cylinder 23 connected to the middle-roof outer side panel stamping head 21. The output shaft of the push-pull cylinder 23 extends, pushing the middle-roof outer side panel stamping head 21 to move downward until the bottom of the middle-roof outer side panel stamping head 21 reaches the preset stamping working height. At this time, the control system feeds back the adjustment completion signal, and the device can start the stamping operation of the middle-roof outer side panel. When switching to produce side panels for low-roof models, the operation process is reversed. The control system first retracts the push-pull cylinder 23 connected to the stamping head 21 of the middle-roof side panel, moving the stamping head 21 back to the non-working area. Then, it extends the push-pull cylinder 23 connected to the stamping head 22 of the low-roof side panel, pushing the stamping head 22 to the working position. Once the position is confirmed to be correct, stamping production of the low-roof side panel can begin. The entire adjustment process requires no manual disassembly or mold replacement. The automated control of the push-pull cylinder 23 enables rapid switching, resulting in short adjustment time and high positioning accuracy, effectively ensuring consistent production quality of side panels for models with different roof heights.

[0021] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
