Description

Technical Field

[0001] This application relates to the field of automotive cover punching technology, and more particularly to a punching device. Background Technology

[0002] In the automotive manufacturing industry, airbag covers are a crucial component, serving not only to protect the airbags but also to house the car emblem. As the automotive industry continues to evolve, car exterior designs are becoming increasingly diverse, and car emblem designs are becoming more complex. As a vital identifier of a car brand, the installation method and effect of the emblem significantly impact the overall aesthetics of the vehicle and the brand image. The design and manufacturing technologies for airbag covers are also constantly improving to meet the automotive industry's dual requirements for safety and aesthetics.

[0003] Traditionally, when installing car emblems on car airbag covers, holes are typically punched into the cover. For emblems with relatively regular shapes, a single stamping process can achieve complete punching. This method is relatively simple to operate and has low equipment costs, making it widely used in the automotive manufacturing industry. However, with the diversification of car designs, some emblem shapes have become increasingly complex. Traditional stamping methods may result in inaccurate punching dimensions and uneven edges, thus affecting the installation effect and overall aesthetics of the emblem. Utility Model Content

[0004] To improve the accuracy of punching and ensure the aesthetic appearance of the car logo installation, this application provides a punching device.

[0005] The punching device provided in this application adopts the following technical solution: A punching device includes a frame, a positioning frame, a punching assembly, and a perforating assembly; the positioning frame is slidably connected to the frame and is used for product installation; the punching assembly is used to pre-drill holes in the product, and the perforating assembly is used to punch holes at the pre-drilled locations on the product.

[0006] By adopting the above technical solution, the product is first installed on the positioning frame. The first driving component then moves the positioning frame below the punching assembly for pre-punching. After pre-punching, the first driving component again moves the positioning frame below the punching assembly for punching. This step-by-step processing method effectively solves the problem of inaccurate punching dimensions for complex-shaped car logos, improving the installation effect and overall aesthetics of the logo. Compared with the traditional single-stamping method, this represents a significant improvement, while also avoiding excessive processing costs and time, thus increasing production efficiency.

[0007] Optionally, the frame is provided with a first driving member, which is used to drive the positioning frame to move relative to the frame.

[0008] By adopting the above technical solution, the positioning frame can be moved relative to the frame by the first driving component, and the product installed on the positioning frame can be smoothly switched between the punching component and the perforation component. This realizes the processing flow of pre-punching the product before punching it, which is convenient for completing the punching operation of complex-shaped car logos on the car airbag cover.

[0009] Optionally, the first driving component is a rodless cylinder.

[0012] By adopting the above technical solution, the positioning frame and the machine frame can be detachably connected, which facilitates the replacement, maintenance and cleaning of the positioning frame. It also allows the punching equipment as a whole to flexibly adjust the positioning frame according to different product requirements, thereby improving the equipment's versatility and practicality. The method of pre-drilling holes before punching holes can ensure that the punching size of complex-shaped car logos meets the standard.

The second drive unit is mounted on the frame, and the cutter is connected to the mounting bracket. The cutter is used to cut and punch holes in the product.

[0014] By adopting the above technical solution, the product is pre-drilled using the cutter of the punching component. Combined with the punching component, the punching is performed at the pre-drilled position, which can meet the dimensional standard requirements for punching complex-shaped car logos. Connecting the mounting bracket to the output end of the second drive component, with the second drive component mounted on the frame and the cutter connected to the mounting bracket, enables the punching component to work stably.

[0015] Optionally, the mounting bracket is detachably connected to the frame.

[0016] By adopting the above technical solution, the positioning frame and the machine frame can be detachably connected, making it convenient to replace the positioning frame to adapt to different products; the drilling assembly includes a mounting frame, a second drive component and a cutter, which can complete the pre-drilling operation; the mounting frame and the machine frame can be detachably connected, which facilitates the maintenance, replacement and other operations of the drilling assembly.

[0017] Optionally, the frame is provided with an annular pulley, and multiple positioning frames are provided, with the multiple positioning frames arranged at intervals along the length direction of the pulley.

[0018] By adopting the above technical solution, a ring pulley is set on the frame and multiple positioning frames are arranged at intervals along the length of the pulley, which can realize the continuous installation and processing of multiple products, improve the processing efficiency of the punching equipment, and the cooperation of the frame, positioning frames, punching components and punching components can pre-drill the product and then punch the hole at the pre-drilled position, which is suitable for punching processing of complex-shaped car logos and other products.

[0019] Optionally, the pulley is inclined, and the height of the pulley gradually decreases along the direction from the punching assembly to the perforation assembly.

[0020] By adopting the above technical solution, the frame is equipped with an annular pulley, and multiple positioning frames are arranged at intervals along the length of the pulley. The pulley is inclined and its height gradually decreases from the punching component to the perforation component. This allows the product to move naturally to the perforation component for perforation after pre-punching, which facilitates the flow of the product within the equipment and improves processing efficiency.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a punching device.

[0028] Example 1 Reference Figure 1 and Figure 2 A punching device includes a frame 1, a positioning frame 2, a punching assembly 3, and a punching assembly 4. The positioning frame 2 is slidably connected to the frame 1 and is used for product mounting. The punching assembly 3 is used for pre-punching holes in the product, and the punching assembly 4 is used for punching holes at the pre-punched locations on the product. Pre-punching provides a foundation for subsequent punching, resulting in more accurate final punching dimensions. Furthermore, the movable positioning frame 2 facilitates product transfer between different processes.

[0029] Specifically, the positioning frame 2 includes a positioning block 21 and a connecting block 22. The positioning block 21 is used for product clamping. The frame 1 is fixed with a slide rail 11 by bolts. The slide rail 11 is equipped with a slider 12, and the connecting block 22 is used to connect with the slider 12. In this embodiment, the connecting block 22 and the slider 12 are detachably connected, so that the positioning frame 2 can be detachably connected to the frame 1, so as to replace the positioning frame 2 with the corresponding model and size according to different products. The detachable connection between the positioning frame 2 and the frame 1 can be by bolt connection or clamping.

[0030] Furthermore, the frame 1 is provided with a first driving member 13, which drives the slider 12 to slide relative to the slide rail 11, thereby moving the product relative to the frame 1 to bring the product from the position of the punching assembly 3 to the position of the punching assembly 4. In this embodiment, the first driving member 13 is a rodless cylinder to ensure the compactness between the components.

[0031] The punching assembly 3 includes a mounting bracket 31, a second drive component 32, and a cutter 33. The mounting bracket 31 is bolted to the frame 1. The second drive component 32 is bolted to the mounting bracket 31. The cutter 33 is mounted on the output end of the second drive component 32. The second drive component 32 drives the cutter 33 to move up and down, facilitating pre-punching of the product using the cutter 33. In this embodiment, the second drive component 32 is a hydraulic cylinder or an electric switch. The shape of the cutter 33 is designed according to the required punching shape, and the material can be high-speed steel, which has high hardness and wear resistance. It can be understood that multiple cutters 33 are provided, the number of cutters 33 is determined by the number of holes required for punching the product, and the shape of the cutters 33 is determined by the required punching shape for the product.

[0032] The specific structure of the punching assembly 4 is consistent with that of existing punching equipment, and will not be described in detail here.

[0033] The implementation principle of Example 1 is as follows: First, the product is installed on the positioning frame 2. The first driving component 13 drives the positioning frame 2 to move below the punching assembly 3, and the second driving component 32 drives the cutter 33 to pre-punch the product. After pre-punching, the first driving component 13 drives the positioning frame 2 to move below the punching assembly 4 for punching. This step-by-step processing method can effectively solve the problem of inaccurate punching dimensions for complex-shaped car logos, improve the installation effect and overall aesthetics of the car logo, and is a significant improvement compared to the traditional single-stamping method. It also avoids excessive processing costs and time, and improves production efficiency.

[0034] Example 2 Referring to the figure, the difference between this embodiment and embodiment 1 is that the frame 1 is provided with an annular pulley 5, and multiple positioning frames 2 are provided, which are spaced apart along the length of the pulley 5. The first driving member 13 is used to drive the pulley 5 to rotate, thereby driving the positioning frames 2 to move along the length of the pulley 5. In this embodiment, the first driving member 13 is a servo motor, which has precise speed control capability. Thus, the multiple positioning frames 2 are fixed to the pulley 5 by connecting members. As the pulley 5 rotates, the positioning frames 2 pass through the punching assembly 3 and the perforation assembly 4 in sequence, realizing continuous processing.

[0035] Furthermore, the pulley 5 is inclined, and its height gradually decreases along the direction from the punching assembly 3 to the perforation assembly 4. This inclined arrangement allows the product to move more smoothly under the influence of gravity during the transition from the punching to the perforation process, reducing the resistance when the positioning frame 2 moves. Simultaneously, the inclined pulley 5 also makes it easier for debris generated during processing to fall off, keeping the equipment clean.

[0036] The implementation principle of Example 2 is as follows: the arrangement of the annular pulley 5 and multiple positioning frames 2 enables continuous processing of the equipment, improving production efficiency. Multiple positioning frames 2 can simultaneously mount different products, and under the drive of the pulley 5, pre-drilling and punching processes are performed sequentially, greatly shortening the product processing cycle and resulting in a significant performance improvement compared to equipment with a single positioning frame 2.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
