Riveting Process Solutions for Aluminum Alloy Bodies of Rail Vehicles

With the acceleration of global urbanization, the subway, an essential part of urban public transportation, plays a vital role in connecting all city corners. The manufacture and maintenance of subway vehicles are also important. One critical part of the manufacture of subway vehicles is the riveting process of aluminum alloy bodies.

Characteristics of Aluminum Alloy Body:Aluminum alloy bodies have become one of the preferred materials for manufacturing subway vehicles due to their advantages of lightweightness, high corrosion resistance, and convenient surface treatment. It can not only effectively improve the vehicle's loading capacity but also reduce the overall weight of the vehicle. Aluminum alloy material also has good plasticity, which makes it easy to manufacture various vehicle body shapes. However, the aluminum alloy body requires many riveting processes in the manufacturing and assembly process to ensure the overall stability and safety of the body.

Anti-corrosion treatment: The aluminum alloy body is very susceptible to oxidation and corrosion in the use process, so it is necessary to conduct anti-corrosion treatment on the aluminum alloy material before riveting. Generally, the aluminum alloy surface is cleaned, repainted, chemically oxidized, and sprayed with paint. This can effectively improve the corrosion resistance of aluminum alloy materials and extend their service life.

Riveting Process Solutions:Riveting is a joining in which nailed rivets or sets of rivets are used to join two or more metal components. The riveting process is an integral part of manufacturing aluminum alloy car bodies. When performing the riveting process, the following points need to be noted:

1. Sheet metal preparation: before riveting, the sheet metal parts of the car body need to be prepared. This includes cleaning, grinding, and adjusting the shape and size of the sheet metal parts to ensure their flatness and dimensional accuracy.

2. Riveting tool selection: You must choose the appropriate tool in the riveting process. Riveling tools usually used include pneumatic riveting guns, hydraulic riveting guns, and manual riveting guns. According to the specific riveting requirements and the shape of the workpiece, select the appropriate riveting tool for riveting.

3. Riveting technology requirements: The riveting process requires mastery of specific riveting technology, including the selection of riveting points, riveting process control, and riveting quality inspection. The technical requirements of riveting must be paid particular attention when riveting the corners and curved structures of the car body.

4. Quality control: The riveting quality needs to be strictly controlled in the riveting process, including the flatness of the riveted joint, riveting strength and sealing, and other aspects of testing and control to ensure that it meets the requirements.

5. Remedial measures: in the riveting process, sometimes there are some problems, such as loosening at the riveting point, exhaust, and leakage. At this time, it is necessary to take appropriate remedial measures. For example, the loose riveting point for re-riveting, exhaust, and leakage of the place for sealing treatment, etc., to ensure the quality of riveted joints.

Application of riveting process of aluminum alloy car body:The riveting process of aluminum alloy bodies is used to manufacture subway vehicles and is widely used in other engineering fields. For example, it is required in aerospace, automobile manufacturing, and construction engineering. Mastering the riveting process of aluminum alloy car bodies is crucial for improving related industries' productivity and product quality.

 With the continuous progress of science and technology, the riveting process of aluminum alloy car bodies is also developing. In the future, the riveting process of aluminum alloy bodies will pay more attention to process efficiency and product quality. For example, the use of robot automation riveting process, advanced riveting tools and equipment, and the development of more environmentally friendly and energy-saving riveting processes. This will help improve the manufacturing efficiency and product quality of the aluminum alloy body and promote the riveting process of the aluminum alloy body to a higher level of development.

  The riveting process of aluminum alloy car bodies is an essential link in the manufacturing of subway vehicles, which is of great significance in ensuring the safety and reliability of subway vehicles. In future development, the riveting process of aluminum alloy car bodies will pay more attention to technological innovation and process improvement to meet the growing market demand.

Aluminum Low-Profile Rivet Nuts: These low-profile rivet nuts are one-third the weight of steel rivet nuts. They have a low profile for light-duty fastening in low-clearance applications. A cadmium or tin-zinc plating provides corrosion resistance and adds lubricity so they collapse smoothly. When installed, the threaded portion is drawn into the sleeve, creating pressure against the hole to secure the nut. The drill bit size in the table is for material with a 0.030"-0.090" thickness. These rivet nuts may be installed in thicker material but require larger holes. Install them using a hand- or power-driven rivet nut tool. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
