Description

Technical Field

[0001] The utility model relates to the technical field of automobile fender punching, in particular to a punching device for automobile fender processing. Background Art

[0002] Automobile fender punching equipment, as a professional mechanical equipment, plays a vital role in automobile manufacturing, not only significantly improving production efficiency, but also ensuring that the punching quality meets the standards. However, in practical applications, this type of equipment faces some challenges.

[0003] First of all, the working principle of the punching equipment relies on a fixed punching upper die and its connected hydraulic cylinder to perform the punching operation. However, the design characteristics of automobile fenders determine that their edges are often irregular. When these fenders with irregular edges are placed on the die, the edge shape of each fender may be slightly different, which leads to deviations in the punching position.

[0004] This deviation in punching position has a significant impact on the manufacturing process of the vehicle. It may cause the fender to be mismatched with other body parts when assembled, thus affecting the assembly accuracy and appearance quality of the vehicle. To solve this problem, manufacturers may need to repeatedly adjust the position of the fender on the mold, which undoubtedly increases production time and reduces production efficiency.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 - Figure 4 As shown, a punching device for automobile fender processing mainly includes a support frame 1, a workbench 2, a top frame 3, a hydraulic cylinder 6, a punching upper die 7, a punching rod 8, a punching lower die 9 and a fine-tuning seat 5. These components each play a unique role and together constitute an efficient and precise punching system.

[0027] The support frame 1 is the main structure of the whole equipment, which stably supports other parts. The workbench 2 and the top frame 3 are respectively installed in the middle and top of the support frame 1, and the relative position relationship between them ensures the stability and accuracy of the punching operation.

[0028] On the workbench 2, the punching lower die 9 is accurately installed. The punching lower die 9 is a component used to position and fix the automobile fender to be punched, ensuring the accuracy of the punching position. At the same time, a slide bar 10 is also provided at the upper end of the workbench 2, which provides a sliding track for the punching upper die 7, so that the punching upper die 7 can move smoothly along the slide bar 10.

[0029] The punching upper die 7 is mounted on the slide bar 10 and is adapted to the punching lower die 9. The punching upper die 7 is provided with a punching rod 8, which is a key component for performing the punching operation. The position and accuracy of the punching rod 8 directly affect the quality and effect of the punching. In order to ensure the precise position of the punching rod 8, the upper end of the punching upper die 7 is connected to a hydraulic cylinder 6 and is connected to a fine-tuning seat 5. The hydraulic cylinder 6 provides power for the punching operation, and the fine-tuning seat 5 is used to fine-tune the position of the punching rod 8 to meet different punching requirements.

[0030] Two top seats 4 with protrusions 16 are installed on the side wall of the top frame 3. These top seats 4 are firmly fixed on the top frame 3 through the protrusions 16, providing stable support for the entire punching system. A plurality of waist holes 13 are opened on the upper end of the top seat 4, and these waist holes 13 are used to install and fix the limiting rod 11. The limiting rod 11 is connected to the fine-tuning seat 5, which plays a role in limiting and stabilizing the fine-tuning seat 5.

[0031] In addition, in order to facilitate fine adjustment of the position of the punching rod 8, a fastening rod 12 and a lateral limiting rod 14 are also used. The fastening rod 12 is inserted into the waist holes 13 on the top seat 4 and the fine adjustment seat 5 to fix them together. The lateral limiting rod 14 passes through the opening of the fastening rod 12 and is fixed to the top seat 4 by a fastening nut 15. In this way, by adjusting the positions of the fastening rod 12 and the lateral limiting rod 14, fine adjustment of the punching rod 8 can be achieved.

[0032] The punching device has a reasonable structural design, and the connections between the various components are tight and stable. The protrusion 16 is designed as an integral part of the top seat 4, which increases the overall stability. The sliding rod 10 and the limiting rod 11 have the same diameter, making the entire structure more coordinated. At the same time, an anti-slip gasket is provided at the connection between the fastening rod 12 and the top seat 4, which increases the reliability of the connection. The two ends of the lateral limit rod 14 are designed with threads, which are convenient for connection and fixation with the fastening nut 15.

[0033] In actual operation, the hydraulic cylinder 6 provides power to the punching rod 8, so that it can penetrate the automobile fender for punching operation. Through the fine-tuning function of the fine-tuning seat 5, the position of the punching rod 8 can be accurately adjusted to meet the punching requirements of different positions. The entire punching process is stable and efficient, which greatly improves the quality and efficiency of automobile fender processing.

[0034] Punching process: accurately place the automobile fender to be punched on the punching lower die 9, and use the punching lower die 9 to position and fix it to ensure the accuracy of the punching position; check the working conditions of components such as the hydraulic cylinder 6, the punching upper die 7, the punching rod 8 and the fine-tuning seat 5 to ensure that they are in good condition and can work normally.

[0035] Through the preliminary action of the hydraulic cylinder 6, the punching upper die 7 drives the punching rod 8 to move to a position roughly corresponding to the punching lower die 9. At this stage, the punching rod 8 has not yet contacted the automobile fender, and mainly performs rough alignment.

[0036] The position of the punching rod 8 is finely adjusted using the fine adjustment seat 5. The design of the fine adjustment seat 5 allows the horizontal and vertical positions of the punching rod 8 to be adjusted within a small range, ensuring the accuracy of the punching position.

[0037] By adjusting the position of the fastening rod 12 in the waist hole 13 of the top seat 4, the horizontal fine adjustment of the fine adjustment seat 5 can be achieved. At the same time, the combination of the lateral limit rod 14 and the fastening nut 15 is used for vertical fine adjustment.

[0038] During the fine-tuning process, close attention should be paid to the alignment of the punching rod 8 and the punching lower die 9 to ensure that the two are fully matched.

[0039] After the position of the punching rod 8 is finely adjusted, the hydraulic cylinder 6 is started to perform the punching operation. The hydraulic cylinder 6 provides a strong power to make the punching rod 8 penetrate the automobile fender to complete the punching.

[0040] During the punching process, it should be ensured that the punching rod 8 penetrates the fender stably and quickly to avoid deviation or damage.

[0041] After punching is completed, check the punching quality to ensure that the hole position is accurate and the hole edge is smooth and free of burrs.

[0042] If necessary, perform the same punching operation on the next car fender until all fenders are punched.

[0043] Tidy up the work area and clean up the waste and debris generated by punching to prepare for the next operation.

[0044] During the whole punching process, the precise adjustment of the fine-tuning seat 5 and its related parts is the key, which ensures the accuracy of the punching position and the stability of the punching quality. At the same time, the stability of the hydraulic cylinder 6 and the durability of the punching upper die 7 and the punching rod 8 are also important factors to ensure the smooth progress of the punching process.
