Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and processing, specifically a riveting device for automotive parts manufacturing. Background Technology

[0002] With the rapid development of the automotive industry, the types and structures of automotive parts are becoming increasingly complex, placing higher demands on the connection processes of these parts. Currently, the main connection methods for automotive parts include welding, riveting, and bolting. Among these, riveting, as an efficient, energy-saving, and environmentally friendly connection method, is widely used in automotive parts production due to its characteristics of not requiring high temperatures or welding wires.

[0003] However, existing riveting technologies, especially punch riveting, still have many shortcomings. First, insufficient riveting strength is a common problem. Traditional punch riveting methods often result in uneven rivet deformation due to imprecise pressure and speed control, thus affecting the strength of the connection point. Second, unstable processes are also a major drawback of existing riveting technologies. During production, various factors, such as material differences and equipment precision, make it difficult to effectively control riveting quality, thereby affecting the safety and reliability of the entire vehicle.

[0004] Furthermore, the increasing trend towards lightweight vehicles places higher demands on riveting technology. Lightweight materials, such as aluminum alloys and high-strength steel, are being used more and more widely in automotive parts. However, the physical properties of these materials differ significantly from those of traditional materials, making it difficult for conventional riveting techniques to meet their connection requirements. Therefore, developing an efficient and stable riveting method that can adapt to new materials and processes is of great significance for improving the quality of automobile manufacturing.

[0005] In summary, existing riveting technologies are insufficient in terms of riveting strength, process stability, and adaptability, making it difficult to meet the high requirements of the automotive industry for component connection processes. Utility Model Content

[0006] The present invention aims to overcome the defects of the prior art and provide a riveting device for the production of automotive parts, thereby solving the problems of unstable riveting quality, insufficient strength, and low production efficiency in the existing riveting technology.

[0007] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0008] A riveting device for manufacturing automotive parts is characterized in that it comprises an upper die, a rivet, an upper plate, a lower plate, and a lower die arranged sequentially from top to bottom; under the action of the upper die, the rivet enters the upper plate and the lower plate; after riveting is completed, the bottom of the rivet penetrates the upper plate and remains in the lower plate, and the bottom of the rivet spreads out, thereby forming a stable connection structure.

[0009] The riveting device for automotive parts production is characterized in that: the bottom of the rivet is serrated, which enhances the connection strength between the rivet and the lower plate during the riveting process.

[0010] The riveting device for automotive parts production is characterized in that: a groove is provided on the top of the lower die, the groove matching the bottom shape of the rivet, which can guide the lower part of the rivet to disperse after the riveting process is completed.

[0011] The riveting device for manufacturing automotive parts is characterized in that: the inner wall of the rivet is provided with a riveting line.

[0012] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a riveting device for the production of automotive parts, which is simple to operate, more stable than the traditional rivet structure, and has the advantages of high automation, precise positioning, more stable structure and strong safety in the entire riveting process.

[0013] This application uses rivets to connect the upper and lower plates together, forming a robust connection structure. This connection method has high strength and can meet the connection strength requirements of automotive parts.

[0014] The lower half of the rivet is serrated. By precisely controlling the pressure and speed during the riveting process, uniform rivet deformation is ensured. The serrations in the lower half of the rivet improve the strength of the connection point, solving the problem of insufficient riveting strength in traditional riveting methods. This design enhances the connection strength between the rivet and the lower plate, preventing the connection structure from loosening or falling off under stress, thereby improving the stability of the connection.

[0015] The top of the lower die is designed with a groove that matches the shape of the rivet, guiding the lower part of the rivet to disperse during the riveting process. This design further optimizes the connection structure, making the connection point stronger and more stable.

[0016] The rivet has a riveting groove on its inner wall. This design reduces material waste, improves riveting efficiency, and decreases the number of defective products. For the large-scale production of automotive parts, this can significantly reduce production costs and increase production efficiency. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figure 1 , 2 As shown: A riveting device for the production of automotive parts includes an upper die 1, a rivet 2, an upper plate 3, a lower plate 4, and a lower die 5 arranged sequentially from top to bottom; under the action of the upper die, the rivet enters the upper plate and the lower plate; after the riveting is completed, the bottom of the rivet penetrates the upper plate and remains in the lower plate, and the bottom of the rivet spreads out, thereby forming a stable connection structure.

[0022] The bottom of the rivet is serrated to enhance the connection strength between the rivet and the lower plate during the riveting process.

[0023] The lower die has a groove at the top, which matches the shape of the bottom of the rivet. This groove can guide the lower part of the rivet to disperse after the riveting process is completed, thereby further improving the stability of the connection structure.

[0024] The inner wall of the rivet is provided with a riveting line to reduce material waste and improve riveting efficiency, while reducing the number of defective products, thereby achieving cost savings in the production process.

[0025] Working principle:

[0026] First, the rivets are fixed in place by a precision positioning device to prevent misalignment. The lower die is located below the lower plate, and the rivets are located above the upper plate. Under the action of the upper die, the rivets enter both the upper and lower plates. The lower half of the rivet is serrated. After riveting, the bottom of the rivet penetrates the upper plate and remains in the lower plate. The bottom of the rivet spreads out, thus forming a stable connection structure.

[0027] In summary, the beneficial effects of the above claims are mainly reflected in improved connection strength, enhanced connection stability, optimized connection structure, reduced costs and increased efficiency, and improved riveting accuracy.
